Description
COMBINATIONS OF AKT INHIBITOR COMPOUNDS AND CHEMOTHERAPEUTIC
AGENTS, AND METHODS OF USE
PRIORITY OF INVENTION
This application claims priority to United States Provisional Application Number
61/470,803 that was filed on April 1, 2011, and to United States Provisional Application
Number ,624 that was filed on April 1, 2011. The entire content of these provisional
ations are hereby incorporated herein by reference.
FIELD OF THE ION
The invention relates generally to pharmaceutical combinations of compounds with
activity against hyperproliferative disorders such as cancer and which include compounds
that inhibit AKT kinase activity. Also described are methods of using the combinations for in
vitro , in situ, and in vivo diagnosis or treatment of mammalian cells, or associated
pathological conditions.
OUND OF THE INVENTION
Protein kinases (PK) are enzymes that catalyze the phosphorylation of hydroxy
groups on tyrosine, serine and threonine es of proteins by transfer of the terminal
) ate from ATP. Through signal transduction pathways, these enzymes
modulate cell growth, differentiation and proliferation, i.e., virtually all aspects of cell life in one
way or r depend on PK activity (Hardie, G. and Hanks, S. (1995) The Protein Kinase
Facts Book. I and II, Academic Press, San Diego, CA). Furthermore, abnormal PK activity
has been related to a host of disorders, ranging from vely non-life threatening diseases such
as psoriasis to extremely virulent diseases such as astoma (brain cancer). Protein kinases
are an important target class for therapeutic modulation (Cohen, P. (2002) Nature Rev. Drug
Discovery 1:309).

purposes of this invention, beneficial or desired clinical results include, but are not limited to,
alleviation of symptoms, diminishment of extent of disease, stabilized (i.e., not ing)
state of disease, delay or g of disease progression, amelioration or palliation of the
disease state, and ion (whether partial or total), whether detectable or ctable.
"Treatment" can also mean prolonging survival as compared to expected survival if not
ing treatment. Those in need of ent include those already with the condition or
disorder as well as those prone to have the condition or disorder or those in which the
condition or disorder is to be prevented.
The phrase "therapeutically effective amount" means an amount of a compound useful
in the present invention that (i) treats the particular disease, condition, or disorder, (ii)
attenuates, ameliorates, or ates one or more symptoms of the particular disease,
condition, or disorder, or (iii) prevents or delays the onset of one or more symptoms of the
particular disease, condition, or disorder described herein. In the case of cancer, the
therapeutically ive amount of the drug may reduce the number of cancer cells; reduce
the tumor size; t (i.e., slow to some extent and preferably stop) cancer cell infiltration
into peripheral organs; inhibit (i.e., slow to some extent and preferably stop) tumor
metastasis; inhibit, to some extent, tumor growth; and/or relieve to some extent one or more
of the symptoms associated with the cancer. To the extent the drug may prevent growth
and/or kill existing cancer cells, it may be cytostatic and/or cytotoxic. For cancer therapy,
efficacy can be measured, for example, by assessing the time to disease progression (TTP)
and/or determining the response rate (RR).
The terms r" and rous" refer to or describe the physiological condition in
s that is typically characterized by unregulated cell growth. A "tumor" comprises
one or more cancerous cells. es of cancer include, but are not limited to, carcinoma,

acceptable salt may involve the inclusion of another molecule such as an acetate ion, a
succinate ion or other counter ion. The counter ion may be any organic or inorganic moiety
that stabilizes the charge on the parent compound. Furthermore, a pharmaceutically
acceptable salt may have more than one charged atom in its structure. Instances where
multiple charged atoms are part of the pharmaceutically able salt can have multiple
counter ions. Hence, a pharmaceutically acceptable salt can have one or more charged atoms
and/or one or more counter ion.
If the compound is a base, the desired pharmaceutically acceptable salt may be
prepared by any suitable method available in the art, for e, treatment of the free base
with an inorganic acid, such as hydrochloric acid, hydrobromic acid, ic acid, nitric acid,
methanesulfonic acid, oric acid and the like, or with an organic acid, such as acetic
acid, maleic acid, succinic acid, mandelic acid, fumaric acid, malonic acid, pyruvic acid,
oxalic acid, glycolic acid, salicylic acid, a sidyl acid, such as glucuronic acid or
galacturonic acid, an alpha hydroxy acid, such as citric acid or tartaric acid, an amino acid,
such as ic acid or glutamic acid, an aromatic acid, such as benzoic acid or cinnamic
acid, a sulfonic acid, such as p-toluenesulfonic acid or ethanesulfonic acid, or the like. Acids
which are generally considered suitable for the formation of pharmaceutically useful or
acceptable salts from basic pharmaceutical compounds are sed, for e, by P.
Stahl et al, Camille G. (eds.) Handbook of Pharmaceutical Salts. Properties, Selection and
Use. (2002) Zurich: Wiley-VCH; S. Berge et al, l of ceutical Sciences (1977)
66(1) 1 19; P. Gould, ational J. of Pharmaceutics (1986) 33 201 217; Anderson et al,
The Practice of Medicinal Chemistry (1996), Academic Press, New York; Remington’s
Pharmaceutical Sciences, 18th ed., (1995) Mack hing Co., Easton PA; and in The
Orange Book (Food & Drug Administration, Washington, D.C. on their website). These
disclosures are incorporated herein by reference thereto.
If the compound is an acid, the desired pharmaceutically acceptable salt may be
prepared by any suitable method, for example, treatment of the free acid with an inorganic or
organic base, such as an amine (primary, secondary or tertiary), an alkali metal hydroxide or
alkaline earth metal hydroxide, or the like. Illustrative es of suitable salts include, but
are not limited to, organic salts derived from amino acids, such as glycine and arginine,
ammonia, y, secondary, and tertiary amines, and cyclic amines, such as dine,
morpholine and piperazine, and inorganic salts derived from sodium, calcium, potassium,
magnesium, manganese, iron, copper, zinc, aluminum and lithium.
The phrase "pharmaceutically able" indicates that the substance or composition
must be compatible chemically and/or toxicologically, with the other ingredients comprising
a formulation, and/or the mammal being treated therewith.
A "solvate" refers to a physical association or complex of one or more solvent
molecules and a compound useful in the invention. The compounds may exist in unsolvated
as well as solvated forms. Examples of solvents that form es include, but are not
limited to, water, panol, ethanol, methanol, DMSO, ethyl acetate, acetic acid, and
ethanolamine. The term "hydrate" refers to the complex where the solvent molecule is water.
This physical association involves varying degrees of ionic and covalent bonding, including
hydrogen bonding. In certain instances the solvate will be capable of isolation, for example
when one or more solvent molecules are incorporated in the crystal lattice of the lline
solid. Preparation of solvates is generally known, for example, M. Caira et al, J.
Pharmaceutical Sci., 93(3), 601 611 (2004). Similar preparations of solvates, hemisolvate,
hydrates and the like are described by E. C. van Tonder et al, AAPS PharmSciTech., 5(1),
article 12 (2004); and A. L. Bingham et al, Chem. Commun., 603 604 (2001). A typical, nonlimiting
, process es ving the inventive compound in desired amounts of the
desired solvent (organic or water or es f) at a higher than ambient temperature,
and cooling the solution at a rate sufficient to form crystals which are then ed by
standard methods. Analytical techniques such as, for example I.R. spectroscopy, show the
presence of the solvent (or water) in the crystals as a solvate (or hydrate).
The term "synergistic" as used herein refers to a therapeutic combination which is
more ive than the additive effects of the two or more single agents. A determination of
a synergistic interaction between a compound of formula I or a pharmaceutically able
salt thereof and one or more chemotherapeutic agent may be based on the results obtained
from the assays described herein. The results of these assays can be analyzed using the Chou
and Talalay combination method and Dose-Effect Analysis with CalcuSyn software in order
to obtain a Combination Index (Chou and Talalay, 1984, Adv. Enzyme Regul. 55).
The combinations provided by this invention have been evaluated in several assay systems,
and the data can be analyzed ing a standard program for quantifying synergism,
additivism, and antagonism among anticancer agents. The program utilized, for example in
Figure 12, is that described by Chou and Talalay, in "New Avenues in Developmental Cancer
Chemotherapy," Academic Press, 1987, Chapter 2. Combination Index values less than 0.8
indicates synergy, values greater than 1.2 te nism and values between 0.8 to 1.2
indicate additive effects. The combination therapy may provide "synergy" and prove
"synergistic", i.e., the effect ed when the active ingredients used together is greater
than the sum of the effects that s from using the compounds separately. A synergistic
effect may be attained when the active ingredients are: (1) co-formulated and administered or
delivered simultaneously in a combined, unit dosage formulation; (2) delivered by alternation
or in parallel as separate formulations; or (3) by some other regimen. When delivered in
alternation therapy, a synergistic effect may be attained when the compounds are
administered or delivered sequentially, e.g., by different ions in separate es. In
general, during alternation therapy, an effective dosage of each active ingredient is
administered sequentially, i.e., serially, whereas in combination y, effective dosages of
two or more active ingredients are administered together. In some examples, Combination
effects were evaluated using both the BLISS ndence model and the t single
agent (HSA) model (Lehár et al. 2007, Molecular Systems Biology 3:80). BLISS scores
quantify degree of potentiation from single agents and a BLISS score > 0 suggests greater
than simple vity. An HSA score > 0 suggests a combination effect greater than the
maximum of the single agent responses at corresponding concentrations.

Scheme 1
Scheme 1 shows a method of preparing compound 10 of Formula I wherein R1 is H,
R2 is H and R5 is H. Formation of pyrimidine 2 can be accomplished by the reaction of the
keto ester 1 with thiourea in the presence of a base such as KOH in an appropriate solvent,
such as ethanol. After reduction of the mercapto group of compound 2 under standard
reducing conditions (e.g., Raney Ni and NH4OH) to provide compound 3, the
hydroxypyrimidine 3 can be chlorinated under standard conditions (e.g., POCl3 in
DIEA/DCE) to provide compound 4. Compound 4 is then oxidized under standard
conditions (e.g., MCPBA in an appropriate solvent such as CHCl3) to give the pyrimidineoxide
. Treatment of the pyrimidine-oxide with acetic anhydride gives the rearrangement
product 6. nd 7 is obtained by reacting compound 6 with an appropriately
substituted piperidine under rd SNAr reaction conditions to provide compound 7.
Compound 7 is hydrolyzed to e compound 8, which is then deprotected to yield the
intermediate 9. Acylation of the piperazinyl cyclopenta[d]pyrimidine 9 with an appropriated
amino acid in the presence of a coupling reagent such as HBTU, followed by deprotection if
necessary, gives nd 10 of Formula I.

Scheme 2
Scheme 2 shows a method of preparing compounds 22, 25 and 27 of Formula I
wherein R1, R2 and R5 are methyl. According to Scheme 2, bromination of (+)-pulegone 11
with bromine gives the dibromide 12. The treatment of the dibromide 12 with a base such as
sodium ethoxide provides the pulegenate 13. Ozonolysis of the pulegenate 13 gives the
ketoester 14. Treatment of the keto ester 14 with ea in the presence of a base such as
KOH in ethanol, followed by reduction of the mercapto group under standard conditions
(e.g., Raney Ni catalyst in ammonia) affords the hydroxypyrimidine 16. nation of the
hydroxypyrimidine 16 under standard conditions (e.g., POCl3) provides the 4-
chloropyrimidine 17. The oxidation of the 4-chloropyrimidine 17 with an oxidizing agent
such as MCPBA or hydrogen peroxide provides the N-oxide 18. Rearrangement of the N-
oxide 18 with acetic anhydride yields the intermediate 19. Compound 19 is reacted with the
desired zine according to the procedure described in Scheme 1 to e nd 20
where R5 is H and 23 where R5 is Me. Compounds 20 and 23 are ted to chiral
separation using HPLC with chiral stationary and then hydrolyzed upon treatment with a base
such as lithium hydroxide to provide compounds 21 and 24, respectively. After deprotection,
compounds 21 and 24 are then reacted with the appropriate amino acid to provide compounds
22 and 25, respectively.
Alternatively, the 7-hydroxy group of compound 24 may be alkylated with an
alkylation reagent such as an alkyl halide in the presence of a base such as NaH or KOH to
provide compound 26 where R2 is Me. After deprotection, nd 26 is then reacted with
the appropriate amino acid to provide compound 27.

Scheme 3
Scheme 3 shows an ative method of preparing compounds 73 and 74.
According to Scheme 3, ion of 14 using an ammonia synthon gives 63. Pyrimidine
ion using, for example, ammonium formate in the presence of formamide at 50°C-
250°C and/or at high pressure gives the bicyclic unit 64. Activation of 64 using, for example,
POCl3 or SOCl2 gives the activated pyrimidine 65. Displacement of this g group, using
a suitable protected/substituted piperazine at 0°C to 150°C gives the piperazine 66.
Oxidation, using, for example, m-chloroperoxybenzoic acid (“MCPBA” or “m-CPBA”) or
Oxone® at -20°C to 50°C gives the N-oxide 67. Treatment with an acylating agent (e.g.,
acetic anhydride) followed by heating (40°C to 200°C) causes rearrangement to give 68.
Hydrolysis, using, for example LiOH or NaOH at 0°C to 50°C gives the alcohol 69.
Oxidation, using for example, Swern conditions, MnO4 or pyridine-SO3 complex at
appropriate temperatures gives the ketone 70. Asymmetric reduction using, for e, a
catalytic chiral catalyst in the presence of hydrogen, the CBS catalyst or a borohydride
reducing agent in the presence of a chiral ligand gives rise to either the (R) or the (S)
stereochemistry at the alcohol 71 or 72. atively, a non-chiral reducing agent could be
used (e.g., H2, Pd/C), allowing the methyl group on the cyclopentane unit to provide facial
ivity and ultimately diastereoselectivity. If the reduction gives a lower
diastereoselctivity, the diastereomers could be separated by (for example) chromatography,
llization or derivitization. Finally deprotection of the Boc-group, using, for example,
acid at 0°C to 50°C, acylation using an appropriately functionalized amino acid and final
functionalization of the amine of this amino acid (e.g., removal of any protecting group,
alkylation, reductive amination or acylation to introduce new substituents) gives rise to the
final compounds 73 and 74.

Scheme 4
Introduction of a chiral auxiliary (e.g., Evans oxazolidinone, etc.) to nd 1 may
be accomplished by standard acylation procedures to give the ate 2. For example,
treatment of the acid with an activating agent (e.g., COCl2) or mixed anhydride ion
(e.g., 2,2-dimethylpropanoyl chloride) in the presence of an amine base at -20°C to 100°C
followed by treatment with the appropriate chiral auxiliary (X)δ gives nd 2. The
stereochemistry and choice of the chiral auxiliary may determine the stereochemistry of the
newly created chiral center and the reoselectivity. Treatment of compound 2 with a
Lewis acid (e.g., TiCl4) at low temperature (e.g., -20°C to -100°C) and an amine base (e.g.,
Hunig’s base) followed by the use of an appropriately substituted imminium ion sor 3
at low temperature then gives rise to compound 4. The temperature, Lewis acid and chiral
ary may all be expected to influence the diastereoselectivity of the addition adduct.
Finally, saponification under mild conditions (e.g., LiOH/H2O at -10°C to 30°C) gives rise to
the desired acid 5.

Scheme A
Scheme A illustrates a method of preparing optionally substituted β-phenylglycine
amino acids 25 and 26 of the Formula 1A wherein R8 is H, and R6, and R9 and are as defined
herein, t is 0 to 4, and R7 is H or an amine ting group. ing to Scheme A, the
acid 20 is converted to an ester 21 wherein R' is alkyl using standard conditions such as
treatment with an appropriate alcohol (e.g., MeOH) in the presence of a catalytic amount of
an acid such as concentrated H2SO4 or a coupling agent such as DCC/DMAP; or alternatively
by treatment with an appropriate electrophile (e.g., MeI, EtBr, BnBr) in the presence of a
base such as NEt3/DMAP at an appropriate temperature (e.g., -20°C to 100°C). The
appropriate choice of ester is determined by the conditions required to reform the acid at the
end of the sis, with many appropriate examples and ions being listed in
‘Protective Groups in Organic sis’ by Greene and Wuts, Wiley-Interscience, third
n, Chapter 5. Introduction of the hydroxymethyl group to provide compound 22 may be
performed by treatment with an appropriate aldehyde (e.g., formaldehyde) in the presence of
base such as NaOEt at an appropriate temperature (e.g., -20°C to room temperature).
Activation of the alcohol group of compound 22 to form a leaving group (e.g., a mesylate,
tosylate, halide) may be accomplished by treatment with, for example, methanesulphonyl
chloride in the presence of excess base such as NEt3, DIPEA, or DBU at an appropriate
temperature (e.g., -20°C to room temperature). In many cases the olefin 24 can be isolated
directly from this ure, in other cases warming (30°C to 100°C) or additional base (e.g.,
DBU in the case of halide) may be required to complete the elimination to provide compound
24. The activated olefin 24 may be d with the desired primary amine (e.g., ethylamine)
in a suitable solvent, such as THF, at an appropriate temperature (e.g., -20°C to reflux) to
generate the amino ester intermediate. In the case wherein compound 24 has an electron rich
aromatic ring or on poor/bulky primary amine, g (e.g., 30-240°C in a sealed tube)
or microwave chemistry may be required. Protection of the amine group (for e as
Boc-group) may be accomplished using Boc2O under standard conditions to provide
compound 23 wherein Pg is a protecting group. ative protecting groups may be used,
and many appropriate examples are listed in ‘Protective Groups in Organic Synthesis’ by
Greene and Wuts, Wiley-Interscience, third edition, Chapter 7. Saponification of the ester 23
to form the protected amino acid 25 may be accomplished using ions appropriate for
the ester (e.g., aqueous LiOH for methyl , hydrogenation for benzyl esters, acid for t-
butyl esters).
Alternatively, the activated olefin 24 may be treated with a secondary amine (e.g.,
diethylamine) in a suitable solvent such as THF at an appropriate temperature (e.g., -20°C to
reflux) to generate the aminoester intermediate (not shown). In the case wherein compound
24 has an electron rich ic ring or electron poor/bulky ary amine, heating (e.g.,
30-240°C in a sealed tube) or microwave chemistry may be required. Saponification of the
ester to form the amino acid 26 may be accomplished using conditions appropriate for the
ester (e.g., aqueous LiOH for methyl esters, hydrogenation for benzyl esters, acid for t-butyl
esters, etc.).

acids 30 and 31 of Formula 1A wherein R8 is OH, and R6, and R9 are as d herein, t is 0
to 4, and R7 is as defined herein or an amine protecting group. Oxidation of the unsaturated
ester 24 (prepared according to Scheme A), n t is 0-4 and R' is alkyl, using a rd
oxidizing agent such as MCPBA at an appropriate temperature (room temperature to reflux)
provides the epoxide intermediate 28. Intermediate 28 may be treated with an appropriate
amine, typically at high temperature (e.g., 50-300°C) and high pressure (e.g., in a sealed tube
or a bomb) to give the amino alcohol 29 or 30. If a secondary amine is used (such as in the
preparation of compound 30), then deprotection of the ester using conditions listed in
ctive Groups in Organic Synthesis’ by Greene and Wuts, Wiley-Interscience, third
edition, Chapter 5 may be used (e.g., LiOH for a methyl ester, hydrogenation for a benzyl
ester, etc). When a primary amine is used (such as in the preparation of compound 29),
protection of the amine (e.g., as a oup using Boc anhydride) followed by deprotection
of the ester (using the above conditions) provide the ylated amino acid 31.

Scheme C shows a method of preparing optionally substituted β-phenylglycine amino
acids 36 of the a 1A wherein R8 is methyl, R6 is H, R7 is an amine protecting group t
is 0 to 4, and R9 is as defined herein. The ester 32, wherein R''' is alkyl, can be d with a
base (e.g., NaOtBu) at an appropriate temperature (e.g., 0°C to reflux) to form the anion,
followed by addition of an electrophile (e.g., utyl 2-bromoacetate) at an appropriate
temperature (e.g., -78°C to room temperature) to give the homologated ester 33. Removal of
the t-butyl ester of compound 33 using an appropriate acid such as TFA or HCl at an
appropriate temperature (e.g, 0°C to reflux) es compound 34. A Curtius rearrangement
of compound 34 using, for example, DPPA in the presence of mild base such as NEt3 at an
appropriate temperature (e.g., 0°C to ), followed by treatment of the ve
intermediate with an alcohol (e.g., t-BuOH), optionally in the presence of a Lewis acid (e.g.,
SnCl2) at higher temperature (e.g., 40-200°C) provides compound 35 wherein Pg is an amine
protecting group. The choice of alcohol used to prepare compound 35 determines the amine
protecting group (e.g., t-BuOH es the Boc-amine). Deprotection of the ester group of
compound 35 using standard conditions (e.g., with LiOH when the protecting group is a
methyl ester, hydrogenation for a benzyl ester, etc.) gives the acid compound 36.
In one alternative of Scheme C, R8 may be methyl, H or F.
In another alternative of Scheme C, Pg may be substituted with R7 in compounds 35
and 36.

R7 is an amine ting group such as Boc. The starting unsaturated ester 24, prepared
according to Scheme A, can be treated with a substituted nitromethane tive (e.g.,
nitroethane) in the presence of a base such as DBU at an appropriate temperature (e.g., 0°C to
room ature) to give the homologated adduct 37. The nitro group of compound 37 can
be reduced using standard conditions (e.g., hydrogenation, Zn/acid, etc.) at an appropriate
temperature (e.g., room temperature to reflux), and the resulting intermediate can be cyclized
to give the lactam intermediate 38. Protection of the amine, for example with a Boc-group to
provide compound 39, may be accomplished using Boc2O under standard conditions.
Alternative ting groups may be used, and many appropriate examples are listed in
‘Protective Groups in c sis’ by Greene and Wuts, Wiley-Interscience, third
edition, Chapter 7. Treatment of compound 39 with an s base such as LiOH or KOH
at an appropriate temperature (e.g., 0 to 100°C) effects ring opening of the lactam to give the
appropriately substituted protected amino acid compound 40.
In one alternative of Scheme D, Boc may be replaced with R7 in compounds 39 and

Scheme D1 shows representative methods of forming the single enantionmers of the
gamma amino acids 40d and 40e, wherein Rc, Rd, and R9 are as defined herein, t is 0 to 4, R6
is H, and R7 is an amine protecting group such as Boc. In one possible method, the racemic
amino acid is subject to chiral chromatographic separation using a chiral stationary phase.
Alternatively, a diastereomeric mixture may be prepared which could be separated by
conventional chromatographic techniques. For example, activation of compound 40 (e.g.,
COCl2, base) and introduction of a chiral ary (e.g., an Evans’ idinone) in the
presence of a basic amine (e.g., Hunig’s base) at -20°C to 50°C gives the diastereomeric
mixture of compounds 40b and 40c. This mixture may be separated using standard
conditions (e.g., column chromatography, HPLC, SFC, etc.) to give the individual
diastereomers. These may be converted to the desired acids by cleavage of the chiral
auxiliary (in the case of an Evans’ auxiliary, by using (for example) OOH at -15°C to
room temperature) to give the compounds 40d and 40e. The temperature may need to be kept
low so as to t racemisation of the newly separated chiral center.

to form the anion, followed by addition of an acrylate unit (e.g., t-butylacrylate) at a
temperature g from -78°C to room temperature to give the homologated ester 41.
Saponification of the t-butyl ester of compound 41 by treatment with a suitable acid such as
TFA or HCl at an appropriate temperature (e.g, 0°C to reflux) provides compound 42. A
Curtius rearrangement of compound 42 using, for example, DPPA in the presence of mild
base such as NEt3 at an appropriate temperature (e.g., 0°C to reflux), followed by treatment
of the reactive intermediate with an appropriate alcohol (e.g., tBuOH), optionally in the
presence of a Lewis acid (e.g., SnCl2) at elevated temperatures (e.g., 40-200°C) provides
compound 43. The choice of alcohol determines the amine protecting group of compound 43
(e.g., tBuOH provides the Boc-amine). ection of the ester of compound 43 under
standard conditions (e.g., LiOH for a methyl ester, hydrogenation for a benzyl ester, etc.)

ature (e.g., room temperature to reflux) to give the unsaturated ester 46. Reduction of
the olefin and the nitrile groups of compound 46 to provide compound 47 may be
accomplished in a number of ways. For example, the olefin may be reduced with any agent
known to effect ductions, such as NaBH4. The nitrile may be reduced using agents
such as LiAlH4 or NaBH4 in the presence of a Lewis acid such as BF3.OEt2 or TFA. A

acid 57 is converted to an ester 58 using standard conditions such as ent with an
appropriate alcohol (e.g., MeOH) in the ce of either catalytic acid (e.g., concentrated
H2SO4 or TMSCl) or a coupling agent (e.g., DCC/DMAP); or alternatively by treatment with
an appropriate electrophile (e.g., MeI, EtBr, BnBr) in the presence of a suitable base such as
NEt3/DMAP at appropriate temperatures (e.g., -20°C to 100°C). The appropriate choice of
ester is determined by the conditions required to reform the acid at the end of the synthesis,
such as described in ‘Protective Groups in Organic Synthesis’ by Greene and Wuts, Wiley-
Interscience, third edition, Chapter 5. Cyclization of compound 58 to provide compound 59
may be achieved using, for example, N-(methoxymethyl)(phenyl)-N-

generates the benzylamine, which can be cleaved to provide compound 60 under standard

Scheme J
Either enantiomer of the b-amino acids may be prepared using a procedure such as
that shown in Scheme J. A ylacetate d with an appropriate chiral auxillary (R*)
(for example, an Evans’ auxiliary or a Sultam) with the riate stereochemistry to
te the d chemistry at the b-position of the amino acid may be treated with an
imine or iminium ion synthon (e.g., prepared in situ by the presence of a Lewis acid (e.g.,
TiCl4) and an appropriately substituted alkoxymethanamine or N-
(alkoxymethyl)amide/carbamate at -100°C to 50°C). The asymmetric addition may require
the presence of Lewis acids (e.g., TiCl4), amine bases (e.g., Hunig’s base) and lower
temperatures (e.g., -100°C to 0°C) to generate the best levels of stereochemical induction. If
the de is lower than required, the separate diastereomers may be separated at this stage by
(for example) chromatography or llization. Cleavage of the chiral auxillary, using
methods known to cleave the chosen auxillary (e.g., LiOH/H2O2 at -50°C to 50°C for the
Evans auxillary) then leads to the desired N-protected b-amino acid with the d
stereochemistry at the b-position. Additionally, if R6 is also a protecting group (e.g., 2,4-
dimethoxybenzyl), it may be removed in the presence of the Boc-group (e.g., hydrogenation
or DDQ, etc.) to give the Boc-amino acid, which upon removal of the Boc-group would
provide the primary amine, which may be further functionalized by alkylation, acylation or
reductive amination (either prior to or after coupling with the pyrimidine-piperazine unit).
In preparing compounds of Formula I, protection of remote functionalities (e.g.,
y or secondary amines, etc.) of intermediates may be necessary. The need for such
protection will vary depending on the nature of the remote functionality and the conditions of
the ation methods. le amino-protecting groups (NH-Pg) include acetyl,
trifluoroacetyl, t-butoxycarbonyl (BOC), oxycarbonyl (CBz) and 9-
fluorenylmethyleneoxycarbonyl (Fmoc). The need for such protection is readily determined
by one skilled in the art. For a general description of protecting groups and their use, see T.
W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, New York, 1991.
S OF SEPARATION
In any of the synthetic methods for preparing compounds of a I, it may be
advantageous to te reaction products from one another and/or from starting materials.
The d products of each step or series of steps is separated and/or purified to the desired
degree of homogeneity by the techniques common in the art. Typically such separations
involve multiphase extraction, crystallization from a solvent or solvent mixture, distillation,
sublimation, or chromatography. Chromatography can involve any number of methods
including, for example: reverse-phase and normal phase; size exclusion; ion exchange; high,
medium and low re liquid chromatography s and apparatus; small scale
analytical; simulated moving bed (SMB) and preparative thin or thick layer chromatography,
as well as techniques of small scale thin layer and flash chromatography.
Another class of separation s involves treatment of a reaction mixture with a
reagent selected to bind to or render otherwise separable a desired product, unreacted starting
material, reaction by product, or the like. Such reagents include adsorbents or absorbents
such as activated carbon, molecular sieves, ion exchange media, or the like. Alternatively,
the reagents can be acids in the case of a basic material, bases in the case of an acidic
material, g reagents such as antibodies, binding proteins, selective chelators such as
crown ethers, liquid/liquid ion extraction ts (LIX), or the like.
Selection of appropriate methods of separation depends on the nature of the materials
involved. For example, boiling point and molecular weight in distillation and sublimation,
presence or e of polar functional groups in chromatography, stability of materials in
acidic and basic media in multiphase extraction, and the like. One skilled in the art will apply
ques most likely to achieve the desired separation.
Diastereomeric mixtures can be ted into their individual diastereomers on the
basis of their physical chemical differences by methods well known to those skilled in the art,
such as by chromatography and/or fractional crystallization. Enantiomers can be separated
by converting the enantiomeric mixture into a diastereomeric mixture by on with an
appropriate lly active compound (e.g., chiral auxiliary such as a chiral alcohol or
Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the
individual diastereoisomers to the corresponding pure enantiomers. Also, some of the
compounds useful in the present invention may be somers (e.g., substituted biaryls) and
are considered as useful in this invention. Enantiomers can also be separated by use of a
chiral HPLC column.
A single stereoisomer, e.g., an enantiomer, substantially free of its stereoisomer may
be ed by resolution of the c mixture using a method such as formation of
diastereomers using lly active resolving agents (Eliel, E. and Wilen, S.
"Stereochemistry of Organic Compounds," John Wiley & Sons, Inc., New York, 1994;
Lochmuller, C. H., J. Chromatogr., (1975) 113 (3):283-302). Racemic mixtures of chiral
nds useful in the invention can be separated and isolated by any suitable method,
including: (1) ion of ionic, diastereomeric salts with chiral compounds and separation
by fractional crystallization or other methods, (2) formation of diastereomeric nds
with chiral derivatizing reagents, separation of the diastereomers, and conversion to the pure
stereoisomers, and (3) separation of the ntially pure or enriched stereoisomers directly
under chiral ions. See: "Drug Stereochemistry, ical Methods and
Pharmacology," Irving W. Wainer, Ed., Marcel Dekker, Inc., New York (1993).
Under method (1), diastereomeric salts can be formed by reaction of enantiomerically
pure chiral bases such as brucine, quinine, ephedrine, strychnine, α-methyl-βphenylethylamine
(amphetamine), and the like with asymmetric compounds bearing acidic
functionality, such as carboxylic acid and sulfonic acid. The diastereomeric salts may be
induced to separate by onal crystallization or ionic chromatography. For separation of
the optical isomers of amino compounds, addition of chiral carboxylic or sulfonic acids, such
as camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid can result in formation of
the diastereomeric salts.
Alternatively, by method (2), the substrate to be resolved is reacted with one
enantiomer of a chiral compound to form a diastereomeric pair (E. and Wilen, S.
"Stereochemistry of Organic Compounds", John Wiley & Sons, Inc., 1994, p. 322).
Diastereomeric nds can be formed by ng asymmetric compounds with
enantiomerically pure chiral derivatizing reagents, such as menthyl derivatives, followed by
separation of the diastereomers and hydrolysis to yield the pure or enriched enantiomer. A
method of determining optical purity involves making chiral esters, such as a menthyl ester,
e.g., (-)menthyl chloroformate in the presence of base, or Mosher ester, α-methoxy-α-
(trifluoromethyl)phenyl acetate (Jacob III. J. Org. Chem., (1982) 47 :4165), of the racemic
mixture, and analyzing the 1H NMR spectrum for the presence of the two atropisomeric
enantiomers or diastereomers. Stable diastereomers of atropisomeric nds can be
separated and ed by normal- and reverse-phase chromatography ing methods for
tion of atropisomeric naphthyl-isoquinolines (WO 96/15111). By method (3), a
racemic mixture of two enantiomers can be separated by chromatography using a chiral
nary phase ("Chiral Liquid Chromatography" (1989) W. J. Lough, Ed., Chapman and
Hall, New York; Okamoto, J. of Chromatogr., (1990) 513 :375-378). Enriched or purified
enantiomers can be distinguished by methods used to distinguish other chiral molecules with
asymmetric carbon atoms, such as optical rotation and circular dichroism.

Trastuzumab PTIN, huMAb4D5-8, rhuMAb HER2, Genentech) is a
recombinant DNA-derived humanized, IgG1 kappa, monoclonal antibody n of the
murine HER2 antibody which selectively binds with high affinity in a cell-based assay (Kd =
nM) to the extracellular domain of the human mal growth factor receptor2 protein,
HER2 ) (US 5821337; US 6054297; US 6407213; US 6639055; Coussens L, et al
(1985) Science 230:1132-9; Slamon DJ, et al (1989) Science 244:707-12). Trastuzumab
contains human framework regions with the complementarity-determining regions of a
murine antibody (4D5) that binds to HER2. Trastuzumab binds to the HER2 antigen and thus
inhibits the growth of cancerous cells. Trastuzumab has been shown, in both in vitro assays
and in animals, to inhibit the proliferation of human tumor cells that overexpress HER2
(Hudziak RM, et al (1989) Mol Cell Biol 9:1165-72; Lewis GD, et al (1993) Cancer Immunol
ther; 37:255-63; Baselga J, et al (1998) Cancer Res. 58:2825-2831). Trastuzumab is
a mediator of antibody-dependent cellular cytotoxicity, ADCC ing TE, et al (1996)

Oncology 26(4), Suppl 12:60-70; Yarden Y. and Sliwkowski, M. (2001) Nature Reviews:
Molecular Cell Biology, Macmillan Magazines, Ltd., Vol. 2:127-137). HERCEPTIN was
approved in 1998 for the treatment of patients with ErbB2-overexpressing metastatic breast
cancers (Baselga et al, (1996) J. Clin. Oncol. 14:737-744). The FDA approved
HERCEPTIN in 2006 as part of a treatment regimen containing doxorubicin,
cyclophosphamide and paclitaxel for the adjuvant treatment of patients with HER2-positive,
node-positive breast cancer. There is a significant clinical need for developing further HER2-
directed cancer therapies for those patients with verexpressing tumors or other
diseases associated with HER2 expression that do not respond, or respond poorly, to
TIN treatment.
Pertuzumab ARG™, rhuMab 2C4, Genentech) is a al stage, humanized
antibody and the first in a new class of agents known as HER dimerization inhibitors (HDIs)
which block the ability of the HER2 receptor to orate with other HER receptor family
members, i.e. HER1/EGFR, HER3, and HER4 (US 6949245; Agus et al (2002) Cancer Cell
2:127–37; Jackson et al (2004) Cancer Res 1–9; Takai et al (2005) Cancer 104:2701–
8). In cancer cells, interfering with HER2's ability to collaborate with other HER family
ors blocks cell signaling and may ultimately lead to cancer cell growth inhibition and
death of the cancer cell. HDIs, because of their unique mode of action, have the potential to
work in a wide variety of tumors, including those that do not press HER2 (Mullen et al
(2007) Molecular Cancer eutics 00).

PHARMACEUTICAL COMPOSITIONS
Pharmaceutical compositions or formulations described include combinations of
Formula I compounds, a chemotherapeutic agent, and one or more pharmaceutically
acceptable carrier, glidant, diluent, or excipient.
One example includes a first formulation for oral ry of a nd of formula
I, or a salt thereof, and one or more pharmaceutically acceptable carrier, glidant, diluent, or
excipient, and a second formulation for oral delivery of vemerafenib, or a salt thereof, and
one or more pharmaceutically acceptable carrier, glidant, diluent, or excipient. In one
example, the first formulation comprises 68 or a salt thereof.
The Formula I compounds, and chemotherapeutic agents useful in the present
invention may exist in unsolvated as well as solvated forms with ceutically acceptable
solvents such as water, ethanol, and the like, and it is intended that the invention e the
use of both solvated and unsolvated forms.
The Formula I compounds, and chemotherapeutic agents useful in the present
invention may also exist in different tautomeric forms, and all such forms are embraced for
use within the scope of the invention. The term "tautomer" or "tautomeric form" refers to
structural isomers of different energies which are interconvertible via a low energy barrier.
For example, proton tautomers (also known as prototropic tautomers) include
interconversions via migration of a proton, such as keto-enol and enamine
isomerizations. Valence tautomers e interconversions by reorganization of some of the
bonding electrons.
Pharmaceutical compositions encompass both the bulk ition and individual
dosage units comprised of more than one (e.g., two) pharmaceutically active agents including
a a I compound and a chemotherapeutic agent selected from the lists of the additional
agents described , along with any pharmaceutically inactive excipients, diluents,
carriers, or glidants. The bulk composition and each dual dosage unit can contain fixed
amounts of the aid pharmaceutically active agents. The bulk composition is material
that has not yet been formed into dual dosage units. An illustrative dosage unit is an
oral dosage unit such as s, pills, capsules, and the like. Similarly, the herein-described
method of ng a patient by administering a pharmaceutical composition described herein
is also intended to encompass the administration of the bulk composition and individual
dosage units.
ceutical compositions also embrace isotopically-labeled compounds useful in
the present invention which are identical to those recited herein, but for the fact that one or
more atoms are replaced by an atom having an atomic mass or mass number different from
the atomic mass or mass number usually found in nature. All isotopes of any particular atom
or element as specified are contemplated within the scope of the compounds useful in the
invention, and their uses. Exemplary isotopes that can be incorporated into nds
include isotopes of hydrogen, carbon, nitrogen, , orus, sulfur, fluorine, chlorine
and iodine, such as 2H, 3H, 11 C, 13 C, 14 C, 13 N, 15 N, 15 O, 17 O, 18 O, 32 P, 33 P, 35 S, 18 F, 36 Cl, 123 I
and 125 I. Certain isotopically-labeled compounds useful in the present invention (e.g., those
labeled with 3H and 14 C) are useful in compound and/or substrate tissue distribution assays.
Tritiated (3H) and carbon-14 (14 C) isotopes are useful for their ease of preparation and
detectability. Further, substitution with heavier isotopes such as ium (2H) may afford
certain therapeutic advantages resulting from greater metabolic ity (e.g., increased in
vivo half-life or reduced dosage requirements) and hence may be preferred in some
circumstances. Positron emitting isotopes such as 15 O, 13 N, 11 C and 18 F are useful for
positron emission tomography (PET) studies to examine substrate receptor occupancy.
Isotopically labeled compounds useful in the present invention can generally be prepared by
following procedures analogous to those disclosed in the Schemes and/or in the Examples
herein below, by substituting an isotopically labeled reagent for a non-isotopically labeled
reagent.
Formula I nds and herapeutic agents are formulated in accordance with
standard pharmaceutical practice for use in a therapeutic combination for therapeutic
treatment (including prophylactic ent) of hyperproliferative disorders in s
including humans. bed is a pharmaceutical composition comprising a Formula I
compound in association with one or more pharmaceutically acceptable carrier, glidant,
diluent, or excipient.
Suitable carriers, diluents and excipients are well known to those skilled in the art and
include materials such as carbohydrates, waxes, water soluble and/or ble rs,
hydrophilic or hydrophobic materials, gelatin, oils, solvents, water and the like. The
particular carrier, diluent or ent used will depend upon the means and purpose for
which the compound useful in the present invention is being applied. Solvents are generally
selected based on solvents recognized by persons skilled in the art as safe (GRAS) to be
administered to a mammal. In general, safe solvents are non-toxic aqueous solvents such as
water and other non-toxic solvents that are soluble or miscible in water. le s
solvents include water, ethanol, propylene glycol, polyethylene glycols (e.g., PEG 400, PEG
300), etc. and es thereof. The formulations may also include one or more buffers,
stabilizing agents, surfactants, wetting agents, lubricating agents, emulsifiers, suspending
agents, preservatives, antioxidants, opaquing agents, glidants, processing aids, colorants,
sweeteners, perfuming agents, flavoring agents and other known additives to provide an
elegant presentation of the drug (i.e., a compound useful in the t invention or
pharmaceutical composition thereof) or aid in the manufacturing of the pharmaceutical
product (i.e., medicament).
The formulations may be prepared using conventional dissolution and mixing
procedures. For example, the bulk drug substance (i.e., compound useful in the present
invention or stabilized form of the compound (e.g., complex with a extrin tive or
other known complexation agent) is dissolved in a suitable solvent in the presence of one or
more of the excipients described above. The nd useful in the present invention is
typically formulated into pharmaceutical dosage forms to provide an easily controllable
dosage of the drug and to enable patient compliance with the prescribed regimen.
The pharmaceutical ition (or formulation) for application may be packaged in
a variety of ways depending upon the method used for administering the drug. Generally, an
article for distribution includes a container having deposited n the pharmaceutical
formulation in an appropriate form. Suitable ners are well known to those skilled in the
art and include materials such as bottles (plastic and glass), sachets, ampoules, plastic bags,
metal cylinders, and the like. The container may also include a tamper-proof assemblage to
prevent indiscreet access to the contents of the package. In addition, the container has
ted thereon a label that describes the contents of the container. The label may also
include appropriate warnings.
Pharmaceutical formulations of the compounds useful in the t ion may be
prepared for various routes and types of administration. For example, a a I compound
having the desired degree of purity may optionally be mixed with pharmaceutically
able diluents, carriers, excipients or izers gton's ceutical Sciences
(1995) 18th edition, Mack Publ. Co., , PA), in the form of a lyophilized formulation,
milled powder, or an aqueous solution. Formulation may be conducted by mixing at ambient
temperature at the appropriate pH, and at the desired degree of purity, with physiologically
acceptable carriers, i.e., carriers that are non-toxic to recipients at the dosages and
concentrations employed. The pH of the formulation depends mainly on the particular use
and the concentration of compound, but may range from about 3 to about 8.
The pharmaceutical formulation is preferably sterile. In particular, formulations to be
used for in vivo administration must be sterile. Such sterilization is readily accomplished by
filtration through sterile filtration membranes.
The pharmaceutical formulation rily can be stored as a solid composition, a
lized formulation or as an aqueous solution.
The pharmaceutical formulations will be dosed and administered in a fashion, i.e.,
amounts, concentrations, schedules, course, vehicles and route of administration, consistent
with good medical practice. Factors for consideration in this context include the particular
disorder being treated, the particular mammal being treated, the clinical condition of the
individual patient, the cause of the disorder, the site of delivery of the agent, the method of
administration, the scheduling of administration, and other factors known to l
practitioners. The "therapeutically effective amount" of the compound to be administered
will be governed by such considerations, and is the minimum amount necessary to prevent,
ameliorate, or treat the ation factor mediated disorder. Such amount is preferably
below the amount that is toxic to the host or renders the host significantly more susceptible to
bleeding.
As a general proposition, the initial pharmaceutically effective amount of the Formula
I compound administered orally or parenterally per dose will be in the range of about 0.01-
1000 mg/kg, namely about 0.1 to 20 mg/kg of patient body weight per day, with the typical
initial range of nd used being 0.3 to 15 mg/kg/day. The dose of the Formula I
compound and the dose of the chemotherapeutic agent to be administered may range for each
from about 1 mg to about 1000 mg per unit dosage form, or from about 10 mg to about 100
mg per unit dosage form. The doses of Formula I compound and the chemotherapeutic agent
may administered in a ratio of about 1:50 to about 50:1 by , or in a ratio of about 1:10
to about 10:1 by weight.
Acceptable diluents, carriers, excipients and stabilizers are nontoxic to recipients at
the dosages and concentrations employed, and include buffers such as ate, citrate and
other organic acids; antioxidants including ascorbic acid and methionine; preservatives (such
as octadecyldimethylbenzyl ammonium de; thonium chloride; benzalkonium
chloride, benzethonium chloride; , butyl or benzyl alcohol; alkyl parabens such as
methyl or propyl paraben; ol; resorcinol; cyclohexanol; 3-pentanol; and m-cresol); low
molecular weight (less than about 10 residues) polypeptides; proteins, such as serum albumin,
gelatin, or immunoglobulins; hydrophilic polymers such as polyvinylpyrrolidone; amino
acids such as glycine, glutamine, asparagine, histidine, arginine, or lysine; monosaccharides,
disaccharides and other carbohydrates ing glucose, mannose, or dextrins; chelating
agents such as EDTA; sugars such as sucrose, mannitol, trehalose or sorbitol; salt-forming
counter-ions such as sodium; metal complexes (e.g., Zn-protein complexes); and/or non-ionic
tants such as TWEEN, PLURONICS or hylene glycol (PEG). The active
pharmaceutical ingredients may also be entrapped in microcapsules prepared, for example, by
coacervation techniques or by acial polymerization, for example,
hydroxymethylcellulose or gelatin-microcapsules and poly-(methylmethacylate)
microcapsules, respectively, in colloidal drug delivery s (for example, liposomes,
albumin microspheres, microemulsions, nano-particles and psules) or in
macroemulsions. Such techniques are disclosed in Remington's Pharmaceutical Sciences
18th edition, (1995) Mack Publ. Co., Easton, PA.
Sustained-release preparations of Formula I compounds may be prepared. Suitable
examples of sustained-release preparations include semipermeable matrices of solid
hydrophobic polymers containing a nd of Formula I, which matrices are in the form
of shaped articles, e.g., films, or microcapsules. Examples of sustained-release es
include polyesters, hydrogels (for example, poly(2-hydroxyethyl-methacrylate), or poly(vinyl
alcohol)), polylactides (US 3773919), copolymers of L-glutamic acid and gamma-ethyl-L-
glutamate, non-degradable ethylene-vinyl acetate, able lactic acid-glycolic acid
copolymers such as the LUPRON DEPOT (injectable microspheres composed of lactic
acid-glycolic acid copolymer and lide acetate) and poly-D (-) oxybutyric acid.
The pharmaceutical formulations e those suitable for the administration routes
detailed herein. The formulations may conveniently be presented in unit dosage form and
may be prepared by any of the methods well known in the art of pharmacy. Techniques and
formulations lly are found in Remington's Pharmaceutical Sciences 18th Ed. (1995)
Mack Publishing Co., Easton, PA. Such methods include the step of bringing into association
the active ingredient with the carrier which constitutes one or more accessory ingredients. In
l the formulations are prepared by uniformly and intimately bringing into association
the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if
necessary, shaping the product.
Formulations of a compound of Formula I and/or chemotherapeutic agent suitable for
oral administration may be prepared as discrete units such as pills, hard or soft e.g., gelatin
capsules, cachets, troches, lozenges, aqueous or oil suspensions, dispersible powders or
granules, emulsions, syrups or elixirs each containing a predetermined amount of a
compound of Formula I and/or a chemotherapeutic agent. The amount of compound of
Formula I and the amount of herapeutic agent may be formulated in a pill, capsule,
solution or suspension as a combined formulation. Alternatively, the a I compound
and the chemotherapeutic agent may be formulated separately in a pill, e, solution or
suspension for administration by alternation.
Formulations may be prepared according to any method known to the art for the
manufacture of pharmaceutical compositions and such compositions may contain one or
more agents including sweetening agents, flavoring agents, coloring agents and preserving
agents, in order to provide a palatable preparation. Compressed tablets may be prepared by
compressing in a suitable machine the active ingredient in a lowing form such as a
powder or granules, optionally mixed with a binder, lubricant, inert diluent, preservative,
e active or dispersing agent. Molded tablets may be made by molding in a le
machine a e of the powdered active ingredient moistened with an inert liquid diluent.
The tablets may optionally be coated or scored and ally are formulated so as to provide
slow or controlled release of the active ient therefrom.
Tablet excipients of a pharmaceutical formulation may include: Filler (or diluent) to
increase the bulk volume of the powdered drug making up the tablet; Disintegrants to
age the tablet to break down into small fragments, ideally individual drug particles,
when it is ingested and promote the rapid dissolution and absorption of drug; Binder to
ensure that granules and tablets can be formed with the required mechanical strength and hold
a tablet together after it has been compressed, preventing it from breaking down into its
ent powders during packaging, shipping and routine handling; Glidant to improve the
ility of the powder making up the tablet during tion; Lubricant to ensure that the
ing powder does not adhere to the equipment used to press the tablet during
manufacture. They improve the flow of the powder mixes through the presses and minimize
friction and breakage as the finished tablets are d from the ent; Antiadherent
with function similar to that of the glidant, reducing adhesion between the powder making up
the tablet and the machine that is used to punch out the shape of the tablet during
manufacture; Flavor incorporated into tablets to give them a more pleasant taste or to mask
an unpleasant one, and Colorant to aid identification and patient ance.
Tablets containing the active ingredient in admixture with non-toxic pharmaceutically
acceptable excipient which are suitable for cture of tablets are acceptable. These
excipients may be, for example, inert diluents, such as calcium or sodium carbonate, lactose,
calcium or sodium phosphate; granulating and disintegrating agents, such as maize starch, or
alginic acid; binding agents, such as starch, gelatin or acacia; and lubricating agents, such as
magnesium stearate, stearic acid or talc. Tablets may be uncoated or may be coated by
known techniques including microencapsulation to delay disintegration and tion in the
gastrointestinal tract and thereby provide a sustained action over a longer . For
example, a time delay material such as glyceryl monostearate or glyceryl distearate alone or
with a wax may be employed.
For treatment of the eye or other external tissues, e.g., mouth and skin, the
ations are preferably applied as a topical nt or cream ning the active
ingredient(s) in an amount of, for example, 0.075 to 20% w/w. When formulated in an
nt, the active ingredients may be employed with either a paraffinic or a water-miscible
ointment base. atively, the active ingredients may be formulated in a cream with an
oil-in-water cream base.
If desired, the aqueous phase of the cream base may include a polyhydric alcohol, i.e.,
an alcohol having two or more hydroxyl groups such as propylene glycol, butane ol,
mannitol, sorbitol, glycerol and polyethylene glycol (including PEG 400) and mixtures
thereof. The topical formulations may desirably include a compound which enhances
absorption or penetration of the active ingredient through the skin or other affected areas.
Examples of such dermal penetration enhancers include dimethyl sulfoxide and related
analogs.
The oily phase of the emulsions useful in this invention may be constituted from
known ingredients in a known manner, including a mixture of at least one fier with a
fat or an oil, or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included
together with a lipophilic emulsifier which acts as a stabilizer. Together, the emulsifier(s)
with or without stabilizer(s) make up an emulsifying wax, and the wax together with the oil
and fat comprise an emulsifying ointment base which forms the oily sed phase of cream
formulations. Emulsifiers and emulsion stabilizers suitable for use in the formulation e
Tween® 60, Span® 80, cetostearyl alcohol, benzyl alcohol, myristyl alcohol, glyceryl monostearate
and sodium lauryl sulfate.
Aqueous suspensions of the pharmaceutical formulations contain the active materials
in admixture with excipients suitable for the cture of aqueous suspensions. Such
excipients include a suspending agent, such as sodium carboxymethylcellulose,
croscarmellose, povidone, cellulose, hydroxypropyl methylcellulose, sodium alginate,
polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such
as a naturally occurring phosphatide (e.g., lecithin), a condensation product of an alkylene
oxide with a fatty acid (e.g., yethylene stearate), a condensation product of ethylene
oxide with a long chain aliphatic alcohol (e.g., heptadecaethyleneoxycetanol), a sation
product of ethylene oxide with a l ester derived from a fatty acid and a hexitol
anhydride (e.g., polyoxyethylene sorbitan monooleate). The aqueous suspension may also
contain one or more preservatives such as ethyl or n-propyl p-hydroxybenzoate, one or more
ng agents, one or more flavoring agents and one or more sweetening agents, such as
sucrose or saccharin.
Pharmaceutical compositions may be in the form of a e injectable ation,
such as a sterile injectable aqueous or oleaginous suspension. This suspension may be
formulated according to the known art using those suitable dispersing or wetting agents and
suspending agents which have been mentioned above. The sterile injectable preparation may
be a solution or a suspension in a non-toxic parenterally acceptable diluent or solvent, such as
a solution in 1,3-butanediol or prepared from a lyophilized powder. Among the acceptable
vehicles and solvents that may be employed are water, Ringer's on and isotonic sodium
de solution. In addition, sterile fixed oils may conventionally be employed as a t
or suspending medium. For this purpose any bland fixed oil may be employed including
synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid may likewise be
used in the preparation of injectables.
The amount of active ingredient that may be ed with the carrier material to
produce a single dosage form will vary depending upon the host treated and the particular
mode of administration. For example, a time-release ation intended for oral
administration to humans may contain approximately 1 to 1000 mg of active material
compounded with an appropriate and convenient amount of carrier material which may vary
from about 5 to about 95% of the total compositions (weight:weight). The pharmaceutical
composition can be prepared to provide easily measurable amounts for administration. For
example, an s on intended for intravenous infusion may contain from about 3 to
500 µg of the active ingredient per milliliter of solution in order that infusion of a suitable
volume at a rate of about 30 mL/hr can occur.
Formulations suitable for parenteral administration include aqueous and non-aqueous
e ion solutions which may contain anti-oxidants, buffers, bacteriostats and solutes
which render the formulation isotonic with the blood of the intended recipient; and aqueous
and non-aqueous sterile suspensions which may include suspending agents and thickening
agents.
Formulations suitable for topical administration to the eye also include eye drops
wherein the active ient is dissolved or suspended in a suitable carrier, especially an
aqueous t for the active ingredient. The active ingredient is preferably present in such
formulations in a concentration of about 0.5 to 20% w/w, for example about 0.5 to 10% w/w,
for example about 1.5% w/w.
Formulations suitable for topical administration in the mouth include lozenges
comprising the active ingredient in a flavored basis, usually sucrose and acacia or tragacanth;
pastilles comprising the active ingredient in an inert basis such as gelatin and in, or
sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid
Formulations for rectal administration may be presented as a suppository with a
suitable base comprising for example cocoa butter or a salicylate.
Formulations suitable for intrapulmonary or nasal administration have a particle size
for example in the range of 0.1 to 500 microns (including particle sizes in a range n
0.1 and 500 microns in increments s such as 0.5, 1, 30 microns, 35 microns, etc.),
which is administered by rapid tion through the nasal passage or by inhalation through
the mouth so as to reach the alveolar sacs. Suitable formulations e aqueous or oily
solutions of the active ingredient. Formulations suitable for aerosol or dry powder
stration may be prepared according to conventional methods and may be delivered
with other therapeutic agents such as compounds heretofore used in the treatment or
laxis disorders as described below.
Formulations suitable for l administration may be presented as pessaries,
tampons, creams, gels, pastes, foams or spray formulations containing in addition to the
active ingredient such rs as are known in the art to be appropriate.
The formulations may be ed in ose or multi-dose containers, for example
sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition
requiring only the addition of the e liquid carrier, for example water, for injection
immediately prior to use. Extemporaneous injection solutions and suspensions are ed
from sterile powders, granules and tablets of the kind previously bed. Preferred unit
dosage formulations are those containing a daily dose or unit daily sub-dose, as herein above
recited, or an appropriate fraction thereof, of the active ingredient.
Further bed are veterinary itions comprising at least one active
ingredient as above defined together with a veterinary carrier therefore. nary carriers
are materials useful for the purpose of stering the composition and may be solid, liquid
or gaseous als which are otherwise inert or acceptable in the veterinary art and are
compatible with the active ingredient. These veterinary compositions may be administered
erally, orally or by any other desired route.
COMBINATION Y
The compound of formula I or a pharmaceutically acceptable salt thereof may be
employed in combination with other chemotherapeutic agents or a pharmaceutically
acceptable salt thereof for the treatment of a hyperproliferative disease or disorder, including
, cancers, and neoplastic tissue, along with pre-malignant and non-neoplastic or nonmalignant
hyperproliferative disorders. In certain embodiments, a compound of Formula I or
a pharmaceutically acceptable salt thereof is combined in a dosing regimen as combination
therapy, with a second compound or a pharmaceutically acceptable salt thereof that has anti-
hyperproliferative properties or that is useful for treating the hyperproliferative disorder. The
second compound of the dosing regimen preferably has complementary activities to the
compound of formula I or a pharmaceutically acceptable salt thereof, and such that they do
not adversely affect each other. Such compounds may be administered in amounts that are
effective for the purpose intended. In one embodiment, the therapeutic combination is
administered by a dosing regimen wherein the therapeutically effective amount of a
compound of formula I, or a pharmaceutically acceptable salt thereof is administered in a
range from twice daily to once every three weeks (q3wk), and the therapeutically effective
amount of the chemotherapeutic agent is administered in a range from twice daily to once
every three weeks.
In one example, in response to the stration of herapeutic agents, for
example docetaxel, cancer cells upregulate pathways, for e the PI3K/AKT y, in
an attempt to circumvent the chemotherapy and become resistant to the chemotherapy. In
another example, certain cancers are associated with mutations in PTEN , PI3K or AKT
that render the cancers inherently resistant to chemotherapy treatments. By dosing
compounds of formual I in combination with the chemotherapeutic agents, compounds of
formula I inhibit the pathways that are upregulated in response to the chemotherapeutic
agents, or have mutations in the PTEN status, PI3K or AKT pathways. In one embodiment,
the combinations herein prevent cancer cells from becoming ant to certain
chemotherapeutic therapies. In r embodiment, the combinations herein treat patients
that have received chemotherapeutic agents but have become resistant to the treatment or
have failed the treatment.
In another example, in response to treatment with Folfox (or one or more of 5-FU,
latin or tin, and folinic acid), certain cancers, for example gastric and colon
cancers, induce an increase in pAKT, which can act as a mechanism of resistance for the
colon cancer in response to the treatment. In another example, certain cancers, for example
gastric and colon cancers, are associated with PTEN, PI3K or AKT ons, which can act
as a mechanism of resistance for the cancer in response to the treatment.
In one embodiment, GDC-0068 or a salt thereof is administered in ations with
Folfox (or one or more of 5-FU, oxaliplatin or cisplatin, and folinic acid) to prevent cancer
cells from becoming resistant to the treatment. In another embodiment, GDC-0068 or a salt
thereof is administered in combinations with Folfox (or one or more of 5-FU, oxaliplatin or
cisplatin, and folinic acid) to treat ts with cancer that have received one or more of the
chemotherapeutic agents but have become resistant to the treatment or have failed the
treatment. In one specific example, the cancer is gastric cancer. In another example, the
cancer is colon cancer.
In another example, certain cancers, for example breast, lung (e.g., non-small lung),
prostate (e.g., CRCP), gastric and head/neck cancer are associated with mutations in PTEN
status, PI3K or AKT, which can act as a mechanism of resistance for the cancer in se
to treatment with taxanes, such as docetaxel or paclitaxel. In one embodiment, GDC-0068 or
a salt thereof is administered in combinations with a taxane (e.g., docetaxel) to prevent cancer
cells from ng resistant to taxane treatment. In another embodiment, GDC-0068 or a
salt thereof is administered in ations with a taxane (e.g., docetaxel) to treat patients
with cancer that have received the taxane but have become resistant to the treatment or have
failed the ent, in one e due to a PTEN status, PI3K or AKT mutation. In one
specific example, the cancer is prostate cancer or hormone refractive prostate cancer. In
another example, the cancer is tion resistant prostate cancer and the combination further
ses hormone y, for example prednisone. In another example, the combination is
ive at does of the taxane that are low enough to prevent harmful side effects from
occurring, such as toxicity, neutropenia, hypersensitivity reactions and fluid retention,
where such doses of the taxane alone would not be effective.
In another example, in response to treatment with taxanes, for example docetaxel or
paclitaxel, certain s, for example prostate cancer (e.g., CRCP), induce an increase in
pAKT, which can act as a mechanism of resistance for the prostate cancer in response to the
treatment. In one embodiment, GDC-0068 or a salt thereof is administered in combinations
with a taxane (e.g., docetaxel) to prevent cancer cells from becoming resistant to taxane
treatment. In another embodiment, GDC-0068 or a salt thereof is administered in
combinations with a taxane (e.g., docetaxel) to treat patients with cancer that have received
the taxane but have become ant to the treatment or have failed the treatment. In one
specific example, the cancer is prostate . In r example, the cancer is castration
resistant prostate cancer and the combination further comprises hormone therapy, for
example prednisone.
The combination therapy may be administered as a simultaneous or sequential
regimen. When administered sequentially, the combination may be administered in two or
more administrations. The combined administration includes coadministration, using
separate ation, and consecutive administration in either order, wherein preferably there
is a time period while both (or all) active agents simultaneously exert their biological
ties.
The compound of formula I or the pharmaceutically acceptable salt thereof can be
administered for a time period of about 1 to about 10 days after administration of the one or
more agents begins. Also described is, the compound of formula I or the pharmaceutically
acceptable salt thereof being administered for a time period of about 1 to 10 days before
administration of the combination begins. Also described is, stration of the compound
of formula I or the pharmaceutically acceptable salt thereof and administration of the
chemotherapeutic agent beginning on the same day.
Suitable dosages for any of the above coadministered agents are those presently used
and may be lowered due to the combined action (synergy) of the newly identified agent and
other chemotherapeutic agents or treatments, such as to increase the therapeutic index or
mitigate ty or other side-effects or consequences.
In a particular embodiment of anti-cancer therapy, a compound of formula I, or
ceutically acceptable salt thereof, may be combined with a chemotherapeutic agent, as
well as ed with surgical therapy and radiotherapy. The amounts of the compound of
formula I or a pharmaceutically acceptable salt thereof and the other ceutically active
chemotherapeutic agent(s) and the relative timings of administration will be selected in order
to achieve the desired combined therapeutic effect.
ADMINISTRATION OF PHARMACEUTICAL COMPOSITIONS
The compounds may be administered by any route appropriate to the condition to be
treated. Suitable routes include oral, parenteral (including subcutaneous, intramuscular,
intravenous, intraarterial, tion, intradermal, intrathecal, epidural, and infusion
ques), transdermal, rectal, nasal, l (including buccal and sublingual), vaginal,
intraperitoneal, intrapulmonary and intranasal. Topical administration can also involve the
use of transdermal administration such as transdermal patches or iontophoresis devices.
Formulation of drugs is discussed in Remington's ceutical Sciences, 18th Ed.,
(1995) Mack Publishing Co., , PA. Other examples of drug formulations can be found
in Liberman, H. A. and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel ,
Vol 3, 2nd Ed., New York, NY. For local immunosuppressive treatment, the compounds may
be administered by intralesional administration, including perfusing or otherwise ting
the graft with the inhibitor before transplantation. It will be appreciated that the preferred
route may vary with for e the condition of the recipient. Where the compound is
stered orally, it may be formulated as a pill, capsule, tablet, etc. with a
pharmaceutically acceptable carrier, glidant, or excipient. Where the compound is
administered parenterally, it may be formulated with a pharmaceutically acceptable
parenteral vehicle or diluent, and in a unit dosage injectable form, as detailed below.
A dose to treat human patients may range from about 20 mg to about 1600 mg per day
of the compound of formula I or a pharmaceutically acceptable salt thereof. A typical dose
may be about 50 mg to about 800 mg of the compound. A dose may be administered once a
day (QD), twice per day (BID), or more frequently, depending on the pharmacokinetic (PK)
and codynamic (PD) properties, including tion, distribution, metabolism, and
excretion of the particular compound. In on, toxicity factors may influence the dosage
and administration dosing regimen. When administered orally, the pill, capsule, or tablet
may be ingested twice daily, daily or less frequently such as weekly or once every two or
three weeks for a specified period of time. The regimen may be repeated for a number of
cycles of therapy.

N 2HCl
HO
Preparation of (S)amino(4-chlorophenyl)(4-((5R,7R)hydroxymethyl-6,7-
dihydro-5H-cyclopenta[d]pyrimidinyl)piperazinyl)propanone dihydrochloride
Step 1: To a 1 L round-bottom flask were added (R)-(+)-Pulegone (76.12 g, 0.5
mmol), anhydrous NaHCO3 (12.5 g) and anhydrous ether (500 mL). The reaction mixture
was cooled with ice-bath under nitrogen. The bromine (25.62 mL, 0.5 mmol) was added
dropwise over 30 minutes. The mixture was filtered and carefully added to NaOEt (21%, 412
mL, 1.11 mmol) in an ice-cooled bath. The mixture was stirred at room temperature
overnight and then 1 L of 5% HCl and 300 mL of ether were added. The aqueous phase was
extracted with ether (2 x 300 mL). The combined organic phase was washed with water,
dried and concentrated. The residue was added to a warmed solution of semicarbazide
hydrochloride (37.5 g) and NaOAc (37.5 g) in water (300 mL), and then g ethanol (300
mL) was added to give a clear solution. The mixture was refluxed for 2.5 hours and then
stirred at room temperature overnight. The mixture was treated with 1 L of water and 300 mL
of ether. The aqueous phase was extracted with ether (2 x 300 mL). The combined organic
phase was washed with water, dried and concentrated. The e was purified by vacuum
distillation (73-76°C at 0.8 mm Hg) to give (2R)-ethyl 2-methyl(propan
ylidene)cyclopentanecarboxylate (63 g, 64%). 1H NMR (CDCl 3, 400 MHz) δ 4.13 (m, 2H),

Example 14 In Vitro Cell proliferation Assays
The in vitro potency of the ations of the compound of Example 2 with certain
specific chemotherapeutic agents was measured using the CellTiter-Glo® Luminescent Cell
Viability Assay, cially available from Promega Corp., n, WI. This
homogeneous assay method is based on the recombinant expression of tera luciferase
(US 5583024; US 5674713; US 5700670) and determines the number of viable cells in
culture based on quantitation of the ATP present, an indicator of metabolically active cells
(Crouch et al (1993) J. Immunol. Meth. 160:81-88; US 6602677). The CellTiter-Glo® Assay
was conducted in 96 or 384 well , making it amenable to automated high-throughput
screening (HTS) (Cree et al (1995) AntiCancer Drugs 6:398-404). The homogeneous assay
procedure involves adding the single reagent (CellTiter-Glo® Reagent) directly to cells
cultured in serum-supplemented . Cell washing, removal of medium and multiple
pipetting steps are not required. The system detects as few as 15 cells/well in a ll
format in 10 minutes after adding reagent and mixing.
The homogeneous "add-mix-measure" format results in cell lysis and generation of a
luminescent signal proportional to the amount of ATP present. The amount of ATP is directly
proportional to the number of cells present in culture. The CellTiter-Glo® Assay generates a
"glow-type" luminescent signal, produced by the luciferase reaction, which has a half-life
generally greater than five hours, depending on cell type and medium used. Viable cells are
reflected in ve luminescence units (RLU). The substrate, Beetle Luciferin, is
oxidatively decarboxylated by recombinant firefly luciferase with itant conversion of
ATP to AMP and generation of photons. The extended ife eliminates the need to use
reagent ors and provides flexibility for uous or batch mode processing of multiple
plates. This cell proliferation assay can be used with various multiwell formats, e.g., 96 or
384 well . Data can be recorded by luminometer or CCD camera imaging device. The
luminescence output is presented as ve light units (RLU), measured over time.
The anti-proliferative effects of combinations of the compound of Example 2 and
certain chemotherapeutic agents were measured using the CellTiter-Glo® Assay. EC50 values
were established for the tested compounds and combinations. The range of in vitro cell
potency activities was about 100 nM to about 10 µM. The data in Figure 12 demonstrates
that representative ations provide additive or synergistic ty against a number of
cancer types.
e 15 In Vivo Tumor Xenograft Efficacy
The cy of representative combinations (including those of the ion) may be
measured in vivo by implanting allografts or xenografts of cancer cells in rodents and treating
the tumor-bearing animals with the combinations. Variable results are to be expected
depending on the cell line, the presence or absence of certain mutations in the tumor cells, the
sequence of administration the compound of Example 2 and chemotherapeutic agent, dosing
regimen, and other factors. Subject mice were treated with drug(s) or control (Vehicle) and
monitored over l weeks or more to measure the time to tumor doubling, log cell kill,
and tumor inhibition.
Results for representative combinations (including those of the invention) that were
tested in this model are presented in the Figures.
The data in s demonstrates that representative combinations provide improved
results compared to the administration of the respective agents individually. For example, in
the LuCap35V primary human prostate tumor model the ation of Example 2 and
docetaxel resulted in tumor regressions while the single agent of either compound only
resulted in tumor stasis (Figure 1). Additionally, the ation of e 2 and cisplatin
resulted in greater tumor growth inhibition than either single agent alone in the SKOV3
ovarian human tumor model (Figure 8).
It has been determined that certain combinations ding those of the invention)
provide improved effects against certain cancer ypes. For example, certain
combinations (including those of the invention) provide improved effects against cancers
associated with PTEN mutation, AKT mutation (e.g., overexpression or amplification), PI3K
mutation, or Her2/ErbB2 amplification or mutation. Accordingly, certain combinations
described herein may be particularly useful against these types of cancers. For example, in
gastric cancer, PTEN-loss ts better efficacy with certain combinations ding those
of the invention) (e.g., a compound of formula I with 5-FU/cisplatin), and in prostate cancer a
stronger effect was seen for a combination of a compound of formula I and docetaxel in
PTEN-null lines.
PTEN status may be measured by any suitable means as is known in the art. In one
example, IHC is used. atively, Western blot analysis can be used. Antibodies to PTEN
are commercially available (Cell Signaling Technology, Beverly, MA, Cascade Biosciences,
Winchester, MA). Example procedures for IHC and Western blot analysis for PTEN status
are described in Neshat, M. S. et al. Enhanced sensitivity of PTEN-deficient tumors to
inhibition of FRAP/mTOR, Proc. Natl Acad. Sci. USA 98, 10314–10319 (2001) and ,
A., et. al. Immunohistochemical Evidence of Loss of PTEN Expression in Primary Ductal
Adenocarcinomas of the Breast, American l of ogy, Vol. 155, No. 4, October
1999. Additionally, cancers associated with AKT mutation, PI3K mutation, and with
Her2/ErbB2 amplification or mutation can be identified using techniques that are known in
the art. In one example, PTEN status of a patient or tissue sample is determined using IHC,
and a histo score or HScore is assigned to the sample or patient. An e way of
calculating HScore uses the formula: HScore = lls x 1)+(%2+cells x 2)+(%3+cells x
3) (See Shoman, N, et. al, Mod Path (2005) 18, 250-259). A mean PTEN HScore of noncancerous
tissue from the same patient or a collection of patients can be used to determine
whether patient or sample HScores are low or null. In one example, HScores of less than
about 200 are considered low and pond to PTEN low, and HScores of about 0 are
considered null.
One embodiment described is a method of tumor growth inhibition (TGI) in a patient
suffering from a cancer comprising a PTEN mutation, AKT mutation (e.g., overexpression or
amplification), PI3K mutation, or Her2/ErbB2 amplification or mutation, sing
administering GDC-0068 or a pharmaceutically acceptable salt thereof and one of Folfox, a
platinum agent, irinotecan, docetaxel, bicin, gemcitabine, SN-38, capecitabine,
lomide, paclitaxel, bevacizumab, pertuzumab, tamoxifen, rapamycin and lapatinib or
a pharmaceutically acceptable salt thereof to the patient. In n embodiments, the
ation is synergistic. In certain embodiments, the TGI of the combination is greater
than the TGI of either GDC-0068 or the chemotherapeutic agent alone. In certain
ments, the TGI of the combination is about 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60,
65, 70 or 75 percent greater than the TGI of either GDC-0068 or chemotherapeutic agent
alone.
Methods of measuring TGI are known in the art. In one example method, average
tumor volumes are determined and compared from the patient before and after treatment.
Tumor volumes can be measured in two dimensions (length and width) using any method in
the art, for example UltraCal IV calipers (Fred V. Fowler Company) or by PET (positron
emission tomography), or by some other method. The formula tumor volume (mm3) = h
x width2) x 0.5 can be used. Measuring tumor volumes over multiple time periods can be
done using a mixed-modeling Linear Mixed Effects (LME) approach (Pinheiro et al. 2009).
This ch can address both repeated measurements (and multiple patients). Cubic
regression splines can be used to fit a non-linear e to the time courses of tumor volume
at each dose level. These non-linear profiles can then be related to dose within the mixed
model. Tumor growth tion as a percent of vehicle can be calculated as a percent area
under the fitted curve (AUC) per day in relation to the vehicle, using the following formula:
Using this formula, a TGI value of 100% indicates tumor stasis, r than about 1% but
less than about 100% indicates tumor growth tion, and greater than about 100%
indicates tumor regression.
In certain embodiments, the cancer comprises one or more of AKT, PI3k, PTEN and
HER2 mutations or AKT, PI3k, PTEN or HER2 abberant signaling. In one example, the
cancer is gastric cancer comprising high pAKT activity and PTEN low or null status.
Described is a method for treating a patient having a cancer that is associated with
PTEN on or loss of expression, AKT on or amplification, PI3K mutation or
amplification, or rbB2 amplification sing administering a combination of the
invention to the patient. Also described is a method for identifying a patient having a cancer
that that can be treated with a combination described comprising ining if the patient’s
cancer is associated with PTEN mutation or loss of sion, AKT mutation or
amplification, PI3K mutation or amplification, or Her2/ErbB2 amplification, wherein
association of the patient’s cancer with PTEN mutation or loss of expression, AKT mutation
or amplification, PI3K mutation or amplification, or Her2/ErbB2 ication is indicative
of a cancer that can be treated with a combination (including those of the invention). Also
described is a method further comprising treating the patient so identified with a combination
described.
In another example, the cancer to be treated is associated with PTEN positive, low or
null status in combination with HER2 positive or negative status. Examples include gastric
cancer that is either (i) PTEN negative (HScore less than about 10, or 0) and Her2 negative,
(ii) PTEN low (HScore less than about 200) and Her2 negative, (iii) PTEN negative and Her2
positive, or (iv) PTEN positive and Her2 ve. In this example, the cancer can be treated
with a combination of a formula I compound, e.g., GDC-0068 or a salt thereor, and FOLFOX.
Example 16 Human dosing of GDC-0068
Patients with advanced or metastatic solid tumors were administered a hydrochloride
salt of GDC-0068 orally and the safety, tolerability and response were assessed using, for
e, PET scans and the incidence and nature of dose limiting toxicities (DLTs). Patients
ed doses of 25 (n=3), 50 (n=3), 100 (n=3), 200 (n=3), 400 (n=3), 600 (n=8) and 800
(n=7) mg 68. No DLTs were observed at the 25, 50, 100, 200, 400 or 600 mg doses.
Grade 3 fatigue was observed at the 800 mg dose in one patient. All 3 patients at the 400 mg
dose had greater than about 60% inhibition in the PRAS40 levels (downstream readout of
AKT ing) as measured by IHC or RPPA assay.
Patients suffering from either tion resistant prostate cancer (n=10) or
diagnostically positive metastatic breast cancer (having one or more of PTEN low or null
status, PI3k mutation or AKT mutation or increased expression or ty, n=10) were
administered GDC-0068 orally, once daily for first seven days of a 21 day cycle at doses of
600mg. Figure 21 shows the PET scan responses for the breast cancer patients. Figure 22
shows PET and tumor marker response in Patient 1 of Figure 21, who suffered from HER2-,
PI3K mutant (H1047R) breast cancer. Patient 6 of Figure 24, who suffered from AKT mutant
E17K (PI3K wild type and HScore of 240) breast cancer, had a complete response after cycle
#1 on the PET scan, with all target and non-target lesions PET-negative, and no new lesions
were seen. These responses trate that compounds of formula I, e.g., GDC-0068, treat
patient’s roliferative diseases.
Surrogate PD ker assays
o-GSK-3b in Platelet rich plasma (PRP) was used as a surrogate PD biomarker
to measure Akt pathway inhibition in patients after treatment with GDC-0068 at different
time points. Peripheral blood was collected in Vacutainer ning .38% of citrate as anti-
ant. Blood was spun at 200 g for 15 min at room temperature. The PRP layer was
carefully taken from the tube and then lysed in a buffer containing detergents, protease and
phosphatase inhibitors. Phosphorylated and total GSK-3β levels in PRP lysates were
measured using a phospho-GSK3 β /total-GSK3β multiplexed MSD assay. pGSk-3β levels
were normalized to total GSk-3β levels and post-dose inhibition of pGSk-3β was expressed
as a ratio of the pre-dose levels for each t. A dose- and time-dependent pharmacologic
response was demonstrated, with a decrease in pGSK3β level of ≥ 75% at doses ≥ 200 mg.
Reverse Phase Protein Arrays (RPPA assay)
Core-needle tumor biopsies from patients treated with GDCC0068 were fresh-frozen
in OCT and sectioned into 8 um slices. Tissue was lysed in RPPA lysis buffer containing
TPER, 300 mM NaCl and phosphatase inhibitors. oprotein signatures of the lysates
were analysed using Reverse-Phase protein arrays: s were printed on nitrocellulose
slides and stained with Sypro to determine total protein concentrations. Each slide was
d with a different antibody at 4oC overnight. The data was then normalized to total
n levels and spatial effects were removed using Quadrant median normalization.
Decreases of 60%–70% in pPRAS40 and ~50% decrease in Cyclin D1 (compared with
baseline) ed in all 3 patients treated at 400 mg daily. For methods and overview of
RPPA see: Reverse phase protein microarrays advance to use in al trials, Molecular
gy. 2010 Dec;4(6):461-81, Mueller C et al.
Example 17 Human dosing of 68 in combination with Docetaxel
A 21-day treatment period was run over multiple cycles. Patients with advanced or
metastatic solid tumors were administered a hydrochloride salt of GDC-0068 orally, once
daily, on Days 2 through 15 of all cycles, and docetaxel, 75 mg/m2 IV infusion through a vein
was given over 1 hr on Day 1. Patients were separated into cohorts. Cohort 1 received 100
mg dose of GDC-0068. Cohort 2 received 200 mg, Cohort 3 received 400 mg and Cohort 4
received 600 mg of GDC-0068, respectively. Disease status was ed using Response
Evaluation ia in Solid Tumors, Version 1.1 (RECIST v1.1). The safety and tolerability
were assessed using the incidence and nature of dose limiting toxicities (DLTs) and the
incidence, nature, and severity of adverse events and laboratory abnormalities (graded per
NCI CTCAE v4.03). No DLTs were observed in Cohorts 1, 2 or 3.
Figure 23 shows results of one patient with l response in Akt1 E17K mutation
breast cancer patient. The patient received three courses of prior chemotherapy but failed on
all three. The t was given GDC-0068 on day 2 of the first cycle for about 15 days, once
daily orally, after a treatment of docetaxel on day 1. No therapy was given for the next 28
days. Prior to the combination treatment (at screening), the patient’s tumor was 30.2 by 17.9
mm, and after the first cycle of the combination treatment, the patient’s tumor shrunk to 18.2
by 16.0 mm (a 39% decrease or PR). These responses demonstrate that compounds of
formula I, e.g., 68, in combination with chemotherapeutic agents, e.g., docetaxel,
treat patient’s hyperproliferative diseases, and can treat the diseases after prior treatments fail.
Example 18 Human dosing of GDC-0068 in combination with 5-FU, orin and
oxaliplatin (FOLFOX)
A 14-day treatment period was run over multiple cycles. Patients with advanced or
metastatic solid tumors were administered escalating doses of a hydrochloride salt of GDC-
0068 orally, once daily, on Days 1 through 7 of all cycles, and mFOLFOX6 (Oxaliplatin 85
mg/m 2, orin 400 mg/m2 IV over 2 hr, and 5-fluorouracil 400 mg/m2 IV injection
al bolus) and 5-fluorouracil 2400 mg/m2 IV over 46 hr) were administered as IV
infusions through a vein on Day 1 of each 14-day cycle. Cohort 1 received 100 mg dose of
GDC-0068. Cohort 2 received 200 mg and Cohort 3 received 400 mg of GDC-0068,
respectively. Disease status will be assessed using Response Evaluation Criteria in Solid
Tumors, Version 1.1 (RECIST v1.1). The safety and bility were assessed using the
incidence and nature of dose limiting toxicities (DLTs) and the incidence, nature, and
severity of adverse events and tory abnormalities (graded per NCI CTCAE v4.03). No
DLTs were observed in Cohorts 1 or 2.
Figure 24 shows results of one patient with l response in PIK3CA mutant
squamous carcinoma of . The patient received the above combination therapy. Prior to
the combination treatment (at screening), the patient’s tumor was 22 mm, and after week 8 of
the above ation treatment, the patient’s tumor shrunk to 13.1 mm (a 40% decrease or
PR).
Figure 25 shows results of a treatment of GDC-0068 in ation with FOLFOX
with partial response where patient suffered from oss (Hscore 40), KRAS-Wild-Type
Colorectal Cancer, after failing prior treatments.
These responses demonstrate that compounds of formula I, e.g., GDC-0068, in
combination with chemotherapeutic agents, e.g., docetaxel, treat patient’s hyperproliferative
diseases, and can treat the diseases after prior treatments fail.
