BACKGROUND

(0002) Endometrial cancer (EC) and breast cancer affect thousands of patients in the United States and internationally every year. Endometrial cancer is currently the most common gynecologic malignancy in the United Sta es and the fourth most common cancer among women. The American Cancer Society estimates that there will he 42,160 new cases of uterine cancer in 2009 and 7,7-80 related deaths. Ninety percent of cases occur in women older than 50 years, and the median age at diagnosis is 62 years. Endometrial cancer is more common among white- ^' women than black women, yet mortality rates are higher in the latter. The overall annual- ^' mortality rate in the United States has increased more than 100 percent during the past two decades and is currently four deaths per 100,000 women per year.

(American Cancer Society 2008).

(0003| EC is a heterogeneous disease that has been classified into two subtype based on distinct elmscopathologtcai and molecular characteristics. Type f is estrogen dependent and represents approximately 80% of sporadic cases. This subtype is well differentiated (Grade 1 or 2 endometrioid histology) and has a favorable prognosis. Phosphatase and fensiu homolog ^• on chromosome 10 (PTEN) loss (32-83%) an RAS mutations (10-30%) have been predominantl identified in Type I EC (CMa et at 2005; Doll et al, 2008: Gadducci et al, 2008), Type ϊ I is poorly differentiated (Grade 3 endometrioid, clear cell, and papillary serous ^• carcinoma) and not associated with increased circulating estrogens. This subtype has an aggressive clinical course and poor prognosis, p33 i frequently mutated in Type- II EC (Doll et al, 2008). There is evidence that the P1K.3CA pathway may be activated in both type I and type II EC and by differing mechanisms (Salvesen 2009).

|Oi)04j Standard therapy for newly diagnosed patients includes surgery, radiation, hormone therapy, and chemotherapy. There has not been any treatment approved in the

United States or in Europe .for adjuvant treatment of advanced or recurrent EC. Cispiatin,

I earboplatin, paclitaxel, and doxorubicin have been investigated -as single agents- or in combination for the treatment of primary advanced and recurrent disease. Overall response rates were higher in combination studies than with single agent studies, Paelitasel in combination with carbopktm is increasingly being used as the. referred regimen in advanced and refractory EC based on a favorable toxicity profile and on relative treatment convenience (Akrara ei al. 2005; Scudder et al. 2005). However, toxicity associated with chemotherapy remains problematic and challenging in the therapeutic- field of EC,

{0005} Clinical studies have suggested that response to chemotherapy in EC varies from 17 to 78% in recurrent and advanced disease and is not associated with histologic subtypes. In general, higher response rates to chemotherapy did not correlate with improved survival benefit in EC. However, a randomized controlled trial, comparing the addition of paclitaxel to doxorubicin and cisplatm with doxonibicin and cisplatin has demonstrated an improved survival benefit (median survival of .15.3 versus 12,3 months) associated with an improved response rate (57% versus 34%). Data on progression-free: survival (PFS) and overall survival have been reported in multiple clinical studies comparing chemotherap regimens in advanced or recurrent EG. The median overall survival varied from 7 to 15 months, and the median PFS varied from 2.5 to S months (Carey et al 2006; Humber et a!. 2007; McMeekin et al. 2007),

{00 6} Approximately two-thirds of breast cancers exhibit hprraone-dependeiH growth, primarily involving estrogen, and inhibition of estrogen activity is an important treatment strategy for patients with estrogen, receptor -positive (ER+) breast cancer (demons et al. 2001). Adjuvant .therapy for S years with tamoxifen, which blocks ER activation, has been standard therapy after primary' treatment Aromatase inhibitors prevent estrogen-mediated breast cancer stimulation through suppression of estrogen biosynthesis rather titan b blocking activation of the ER and effectively reduce total estrogen synthesis after menopause (Geisler etal, 2002). Two highl selective nonsteroidal aromatase inhibitors anastrozole (Arimidex$) and ietrpzole (Fe ara®) and the steroidal aromatase inhibitor exetnestan (Aromasia#) are approved for use in both early- and advanced-stage breast ^' cancers in postmenopausal women.

10007} Letrosioie .specifically blocks production of estrogens by competitive, reversible binding to the heme of the cytochrome P450 subtmit of the- enzyme aromatase. Letrozoie has been s n to be more effective in die treatment of metastatic breast cancer and in neoadjuvant and adjuvant ^' settings than tamoxifen (Ellis et al. 200.1; Mouridsen et al.. 2003; The Breast International Group [BIG] Collaborative Group 2005). ^' Leirozole is indicated for the adjuvant treatment of postmenopausal women with .hormone receptor-positive (HR+) early breast cancer, for the extended adjuvant treatment of earl breast, cancer in

postmenopausal omen who have received 5 years of adjuvant ^■■ tamoxifen therapy, for first- line treatment of postmenopausal women with hormone receptor-positive or hormone receptor-unknown locally advanced or metastatic breast cancer, and for the treatment: of advanced breast cancer in postmenopausal women with disease progression following anti-estrogen therapy. Aromatase inhibitors .such as letrozole are effective in treatment of hormone receptor-positive breas cancer; however, many tumors become resistant t aromatase inhibitors. As a result,, a need remains for new therapeutic options for the treatment of breast cancer, particularly hormone receptor-positi ve (ER+ and/or progesterone receptor positive (PGR*)) or HERl-negative (HER2-) breast cancer which is refractory to a nonsteroidal aromatase inhibitor.

|OO08J As -a result, despite the generally favorable prognosis of early stage EC, there remain unmet medical needs for less toxic and- more effective therapies in patients with advanced or recurrent disease, A need also remains for new therapeutic options for the treatment of breast cancer, particularly hormone receptor-positive (ER- and/or progesterone receptor positive (PGR- )} or RER2-negative (HER2-) breast cancer which is refectory to a nonsteroidal aromatase inhibitor.

1 032 The symbol ^■ means it single bond, means a double bond, ^{> ν} means a triple bond, means a single or double bond. The symbol ^B «Aiw" refers to a group on a double-bond as occupying either position on. the terminus of a double bond to which the symbol is attached: that. the geometry, E- or Z- of the double bond is ambiguous, When a group is depicted removed from its parent formula, the " * - " or I ^s mb l will be used at the end of the bond which was theoretically cleaved in order to separate the group from its parent structural formula.

[0033) When chemical structures are depicted or described, unless explicitly stated otherwise, all carbons are assumed to have hydrogen substitution to conform, to a valence of tour. For exampie, in the structure on the left-hand side of the Schematic below (here are nine hydrogens implied. The nine hydrogens are depicted in the right-hand structure. Sometimes a particular atom in a structure is described in te tual formula as having _, a hydrogen or hydrogens as substitution (expressly defined hydrogen), for example, -C¾C1¾-. It is understood by one of ordinary skill in the art thai the aforementioned descriptive techniques are common in the chemical art to provide brevity and simplicity to description of otherwise complex .structures.

Gelatin Capsule Composition of Compound B

G ener a! Ad ministration

[002291 In one aspect, the invention provides pharmaceutical compositions comprising an inhibitor of the FBK.S of Formula I or II and a pharmaceutically acceptable carrier, exeipient or diluent. In certain other specific embodiments, administration is by the oral route.

Administration of the compounds ^' of Formula 1 or la. or their phannaceUiicaliy acceptable salts _* in pure farm or in an appropriate pharmaceutical composition, can be earned out via any of the accepte modes of adnrinisirasio or agents for serving similar utilities. Thus, the Compound of Formula I or II ean be. administered m " die same or separate vehicles.

Administration cm be, for example, orally, .nasally, parenteral ly (intravenous, ratramuseular, or subcutaneous), topically, tratisderoaliy, intravagimd y, infmvesicali , iniracistemaliy, or rectally, in the form of solid, semi-solid, lyophilized powder, or liquid dosage forms, such as for example, tablets^ -suppositories, .pills, soft elastic and hard gelatin capsules, powders, solutions, suspensions, or aerosols, or the like, specifically in unit dosage forms suitable for simple administration of precise dosages.

[00230} The compositions will include a conventional phannaeeutseai carrier or exeipieut and a Compound of Formula I or II as the/an. ac tive agent.

[00231 j Adjuvant include preserving, wetting, suspending, sweetening, flavoring, perftJtning, emulsifying, and. dispensing agents. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, ehlarobmanoi, phenol, sorbie acid, and the like. It may also be desirable to include isotonic agents, tor example sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form ean be brought about by the use of agents delaying absorption, for exampl ,, aluminum monostearate and gelatin.

100232] If desired, a pharmaceutical composition of the invention may also contain minor amounts of auxiliary subs tances such as wetting or emulsifying agents, pH buffering agents, antioxidants^ and die like, such as, for example, citric acid, sorts-tan nlcnioUnnaie, triethanolamine oleate, butylated hydroxytoluene, etc.

j 00233 j The choice of formulation depends on various factors such as the mode of dru administration (e.g., ibr oral administration, formulations in the ibrm of tablets, pills or capsules) and the bioavailability of the drug substance. Recently, pharmaceutical formulations have been developed especially for -drugs that show poor bioavailability based upon the principle that bioavailabilit can ^' be increased by increasing the surface area i.e., decreasing particle size. For example, U.S. Pat, No. 4, 107,288 deseribes a . harmaceutical formulation having particles in the size range from 10 to 1 ,000 ^' ran in which the active material is supported on a cross inked matrix of macromoleeules. li.S. Pat, No, 5, 145,684 describes the production of a pharmaceutical formulation in which the drug substance is pulverized to nanoparticles (average particle size of 400 nra) in the presence of a surface modifier and then dispersed in a liquid medium; to give pharmaceutical formulation that exhibits remarkably high bioavailability. [00234] Compositions- suitable for parenteral injection may comprise physiologically acceptable sterile aqueous. r nonaqueous: solutions, dispersions, suspensions or emulsions, and sterile powders for ^constitution, into sterile injectable solutions or dispersions.

Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol,. polyols (propylenegiyeol, polyethyie.neglyeoL glycerol, and the like), suitable mixtures thereof, vegetable oils (such s olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the ease of di spersions and by the use of surfactants,

{00235] One speci fic route of administration is oral using a convenient daily dosage regimen that can be adjusted according to the degree of severit of the disease-state to be treated.

[002361 Solid dosage forms for oral administration include capsules, tablets, pill ^' s,, powders, and granules. In such solid .dosage forms, the active compound is admixed with at least one inert customary exciplent (or carrier) such as sodium, citrate or dicaicium phosphate or (a) .fillers or extenders, as tor example, starches, lactose, sucrose, glucose, marmiioi, and silicic acid, (b) binders, as for example, cellulose derivatives, starch, alignates, gelatin, polyvinylpyrrolidones. Sucrose, and gum acacia, (c) hismectants, a for example, glycerol, (d) ^' disintegrating agents, as for example, agar-agar,, calcium carbonate, potato or tapioca tarch, alginie acid, croscarme ^' Hose sodium, complex silicates, and sodium carbonate, (e) solution retarders, as for example paraffin, (f) absorption accelerators, as for example, quaternary ammonium compounds, (g) wetting agents, as fo example, cetyl alcohol, and glycerol monastearate, magnesium stearate and the like (h) adsorbents, as for example, kaolin and bentoniJe, and (i) lubricants, as for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also comprise buttering agents.

[00237} Solid dosage forms as described above can be prepared with coatings and shells, such as enteric coatings and others ^' well known in the art They may contain pacifying agents, nd can. als be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedded compositions thai can be used are polymeric substances and waxes. The active compounds can also be in microencapsulated- form, i appropriate, with, one or more of the above-mentioned exeipients,

[00238] l iquid dosage forms for oral administration include phannaceuticaliy acceptable emulsions, solutions, suspensions, syrups, and elixirs. Such dosage forms are prepared, for example, by dissol ving, dispersing, etc., a eompoisrld(s) of the invention, or a

pharmaceutically acceptable, salt thereof,. and optional, pharmaceutical adjuvants in a carrier, such as, for example, water, .saline, -aqueous dextrose, glycerol, ethanol and the like;

stabilizin agents and ettiulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethyl carbo ate, ethyl acetate, benfc l alcohol, -.benzyl benxoate, propyienegiyeo!,

1 ,3-butyieneglycol, dime thylfomiantide; .oils, in particular, cottonseed oil, groundnut oil, com germ oil, olive oil, castor oil and sesame oil, glycerol, tetrahydfofutfury! alcohol,

p lvethyieneglycols and fatty acid esters of sprbitan; or mixtures ^' of these substances, and the like, to thereby form a solution, or suspension.

(002391 Suspensions, in addition to the active co.iripo.unds, may cont in suspending agents, as for exaoipie, ethoxyiated isostea ^' ryl alcohol s¾ pojyoxyethyiene sorbitol and .sorbiian esters, rokroctystalline cellulose, aluramum roetahydroxkle, bentonite, agar-agar and tragaca th, -or mixtures of these substances, and the like.

f0fl24O] Compositions for rectal administrations are, for example, suppositories that can be prepared by- mixing the compounds of the present invention with for example suitable non- irritating exeip ents or carders such as cocoa butter, poiyethylenegtycoi or a suppository wax, which are solid at ordinary temperatures but liquid at. body .temperature and therefore, melt while in a suitable bod cavity and release the active component therein.

((10241} Dosage- forms for topical administration Of a compound of this invention include ointments, powders, sprays, and inhalants. The active component is admixed under ^" sterile conditions with a physiologically acceptable carrier and any preservatives, buffers, or propellaiits as may be required. Ophthalmic formulations, eye ointments, powders, and solutions are also contemplated as being .within the -scope of this invention.

(00242] Compressed ^' gases may be used t disperse a compound of this invention in aerosol form. Inert gases suitable fo this purpose are nitrogen, carbon, dioxide, etc.

(002431 Generally,, depending oft the intended mode of .administration, the

pharmaceutically acceptable compositions will contain about 1 % to about 99% b weight of a eoinpound(s) of the invention, or a pharmaceutically acceptable salt thereo f, and 99% to .1% by weight of a suitable pharmaceutical exeipient. In one example, the composition will be between about 5% an about 75% by weight of a conipound(s) of the invention, or a pharmaceutically acceptable salt thereof, with the rest being suitable pharmaceutical exeipients.

(00244] Actual methods of preparing such dosage forms are known, or will be apparent, to those ski lied in this art; for example, see Remington ^' s Pharmaceutical Sciences, 18th Ed,, (Mack Publishing Company, Easton, Pa., 1990). The composition to be administered will, m any event, contain an effective amount of a compound of the invention, or a pharmaceutically acceptable .salt thereof, for treatment of a disease-stii e in aceordaB.ee with the teachings of this invention.

{00245] In the pharmaceutical compositions disclosed herein, the compounds of Formula I or la, or their -pharmaceutically acceptable salts or solvates, are administered in art .effective amount which will vary depending upon a variety of .factors including the activit of the specific compound employed, the metabolic stability and length of action of the. compound, the age, body weight, genera! health, sex, diet, mode and time of administration . rate of excretion, drug combination., the severity of the particular disease-states, and the host undergoing therapy. The compounds of Formula I or 0 can be administered to a patient at dosage levels in the range of about 0, 1 to about 1 ,000 mg per day, or in the range. f 100 mg to 800 mg per day, orin the range of 200 to 700 ing per day, or hi the range of 300 t 600 mg per day,

(00246 j For a normal human adult having a body weight of about 70 kilograms, a dosage in the range of about 0.01 to about 100 mg per .kilogram of body weight per day is an example. The specific dosage used, however, can vary. For example, the dosage can- depend on a number of factors including the requirements of the patient, the severity of the condition being treated, and the pharmacological activity of the compound being used. The determination of optimum dosages for a ^' particular "patient is well known to one of ordinary skill in the art. I f formulated as a fixed dose, such combination products employ the compounds of this invention within the dosage range described above and the Other pharmaceutically active agent(s) within approved dosage ranges. Compounds of Formula 1 or 1.1 may alternatively be -used sequentially with known phannaceutically acceptable ageni(s) when a combination formulation is inappropriate.

{00253} The compounds of the invention, or their pharmaceutically acceptable salts, may have asymmetric carbon atoms or quatemized nitrogen atoms in their structure- Compounds ^• of Formula I that may be prepared through the syntheses described herei may exist as single stereoisomers, rscemates, and -as mixtures of enantiomers and diastereoroers. The compounds may also exist as geometric isomers. Ail such single stereoisomers, raeemates and mixtures thereof, and geometric isomers are intended to be within, the scope of this invention,

(00254 | Some of the compounds of the.- invention may exist as tautomers. For example, where a ketone or aldehyde is present, the molecule may exist in th euol f rm;- where an amide is present, the molecule may exist as theimidic acid; and where an enamine is present, the molecule ma exist a a inline. All such tautomers are within the -scope of the invention, and to the extent that one structure is used to depict a compound, it includes ail such

tautomeric forms..

100253] Thus, compounds of Formula 1

can exist as. tautomers. in particular,. ring-B in (he Coinptamd of Formula 1 or B can be 2- hydroxy-pyndmyl, also described as its structure:

Compounds of Formula I themselves, can be recovered ess uncharged or zwttteriome molecules, or catioriic salts such a sodium or potassium, depending on the substitutions on the B ring and on reaction conditions. All such zwitierkmic forms are within the scope of the invention, and to the extent that one structure i used to depict a zwittersooie compound, it includes all such xwiiteriomc forms.

and the associated terms "Compound A" and ^< -(3- {[(3- ([2-cHoro-5- {methaxy)pheny.]am _: m^

encompass all possible tautomeric and x htcric c forms of the compound.

(00- 6 ) The present invention also includes -oxide derivatives and protected derivatives of compounds of forrruda f. For example, -when compounds of Formula i contain an oxk&ahie nitrogen atom, the nitrogen atom can be converted to an N-oxide by methods well known in the art. When compounds of Formula I contain groups such as hydroxy, earboxy, thiol, or any group containing a - nitrogen aiomfs), these groups can be protected with a suitable "protecting group" or "protective group " A comprehensive list of suitable protective groups can he found in T.W, Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, Inc. 1991 , the disclosure of which is incorporated herein by reference in its entirety. The protec ted derivatives of compounds of Formula I can be prepared by methods well known in the ait.

|08267 j Methods for the preparation and/or separation and isolation of, single

stereoisomers .from racemic mixtures or son-raeenue mixtures of stereoisomers are well known in the art. For example, optically active ( )- and (S)- isomers may be prepared using chirai sytuhoits or chirai reagents, or resolved using conventional techniques. Enaniiomers (R~ and S-tsosncrs} may be resolved by methods known, to. one of ordinary skill in. the art. for example by; .formation of diastereoisomerie salts or complexes which may be separated, for example, by crystallization; via formation of diastereoisomeric derivatives which may be separated; for example, by crystallization, selective reaction of one enantiomer with an enaiitionier- spec ific reagent, for example enzymatic oxidation or reduction, followed by separation of the modified and unmodified esiamiomers; or gas-liquid or liquid

chromatography in a chirai environment, for example on a chirai support, such as silica with a bound chirai Hgand or i the presence of a chirai solvent, it will be appreciated that where a desired enantiomef.is converted into another chemical entity by one of the separation procedures described above, .a- further step may be required to: liberate the desired

enantiomeric form. Alternatively, speci ic enantiomer may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents or by converting on enantiomer to the other by asymmetric trans formation. For a mixture of enantipmers, enriched in a particular enantiomer, the major component enantiomer may be ^' further enriched (with concomitant loss in yield.). by ree ystailization.

[00268] In addition, the compounds of the present invention can exist in unsolvated as well as soivated forms with pharmaceutically acceptable solvents such as water, ethanoS, and the like, in general, the soivated forms are considered equivalent to the unsolvated forms, .for the purposes of the present invention.

[00269] In the examples thai follow, unless otherwise speci fied, the final, form -of the compound was assumed ^' to be the uncharged molecule in the absence of analytical techniques mat would _, have determ ined otherwise. Compounds of Formula 1 can be prepared using methods known to on of ordinary ski ll in the art: or starting from the Compound of formula 1 as depicted in ^' Scheme 1 below. Compounds of formula l ean be prepared starting from compound 1 by fusion -of appropriate reagents at 180 "C in the presence of a base such as KJCOJ and metallic copper Is known to provide intermediates of formula 1 (see S. H.

Dandegaonker and C, K, esta, , Med. Cfwm. 1965, 8, 884),

[00270} Referring again to Scheme t , an intermediate of formula- 3 can be prepared by ^' briefly !ieating an appropriateiy substituted quinoxalmc (for example _^ commercially available 2,3-dichioroq:uino aliiie) and an appropriately substituted sulfonamide of formula 2

in the art), a base sueh s R.5CO3, in a solvent, such as DMF or DM SO. Upon completion (about 2 hour ^' s), the reaction mixture is then poure into water and followed by 2 N HCI. The product is then- extracted into a solvent such as ethyl acetate -and washed with water and brine. The organic layers are combined and dried over a drying agent such as sodium, sulfate, filtered, and concentrated under -vacuum to provide a compound of formula 3.

{00271 j The intermediate of formula 3 is then treated with an intermediate of formula 4 in a solvent such, as DMF or p-xylene at reflux temperature. Upon completion of the reaction (about 16 hours Or less), die reaction is allowed to cool, extracted into DCM, washed with 2 N HCI and brine, dried over a drying agent soehas sodium sulfate or magnesium sulfate, filtered, and concentrated to give a compound of Formula I

[0629-9! The compounds of the invention, or thei pharmaceutically acceptable salts, may have asymmetric carbon atoms or quaternized nitrogen atoms in their structure. Compounds of formula ί that may be prepared, through the syntheses described herein may exist as single stereoisomers, raeemates, and as mixtures of enantiomers and dsastereotuers. The compounds: may also exist as geometric isomers. Ail such single stereoisomers, mcemaies and. mixtures thereof, and geometric isomers are intended to be within the scope of this invention. Some of the compounds of the invention ma exist as lautome ^' rs. For example, where a ketone or aldehyde is present, the molecule may exist in the enol form; where an amide is present, the molecule may exist as the iraidic acid; and where an enamine is present, the molecule may exist as an iraine. All such tautoraers are within the scope of the invention, in particular, hnidazoI-3-yl and pyrazol-S-yi each can also exist in their respective tautomeric forms t .i a;ioi-4-yl and pyrazol-3-yL Regardless of which structure or which terminology is used, each automer is included within the scope of the invention,

{60300( The present invention also includes -oxide derivatives and protected derivatives of compounds of formula 11, For example, when compounds of formula 1 contain an oxidtzable nitrogen atom, the nitrogen atom can be converted to an N-oxide by methods well known in the ar When compounds of formula I contain groups such as hydroxy, earhoxy, thiol or any group containing _. a nitrogen atom(s), these groups can be protected with a suitable "protecting group" or "protective group". A comprehensive list of suitable protective groups can be found in TvW. Greene, Protective Groups in Organic Synth ix,.

1003011 Methods for the preparation and/or separation and isolation of single

stereoisomers from racemic mi xtures or non-racemie mixtures of stereoisomers are well known, in the art. For example, optically active (!¾■)- and (Sj- isomers raay be prepared using ehiral synthons or ehiral reagents, or resolved using conventional techniques. Enantioniers (R- and. ^-isomers) may be resolved by methods known to one of ordinary skill in the art, for example by: formation of d iastereo isomeric salts or complexes which raay be separated, for example, by crystallization; via formation of diastereoisomerie derivatives which may be separated, for example, by crystallization, selective reaction of one enantiomer with an enantlomer-specific reagent, for example enzymatic oxidation or reduction, followed by separation of the modified and unmodified enantioniers; or gas-liquid or liquid

chromatography in a ehiral environment, lor example on a ehiral support, such as silica with a bound ehiral ligand or in the presence of a ehiral solvent, it will be appreciated that where a desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step may be required to liberate the desired

enantiomeric form, Alternatively, specific enantiomer may be synthesized by asymmetric Synthesis ^' using ^' optically active reagents, substrates, catalysts, or solvents, or by con verting one enantiomer to the other by asymmetric transformation. For a mixture of ertatitiomers, enriched in a particular enantiomer, the major component enantiomer may be further enriched (with concomitant loss in yield} by reerystaUization.

Stage I enrolled 3? evaluable subjects. If at least four subjects had achieved an objective response (a confirmed PH. or a confirmed CR) or at least seven subjects were alive and progression free for at least 6 months,, then the study would have continued to Stage 2 until 71 evaluable subjects (including both stages) ^" have been enrolled.

J00321] As of amendment 3 (Part 2), ^' approximately 45 additional patients will be enrolled to obtain a total of approximately 75 per protocol evaluable patients (including those enrolled in Part 1 }. The primary interest of Part 2 is the estimation of ORR and PFS6 for all patients meeting the Amendment.3 inclusion/exclusion criteria.

[003221 During the course of the study, subjects' tumor samples (archival and/or from new biopsies) will be analyzed for biornarkers thai ma predict increased frequency of response or longer disease stabilization. If molecular profiling data obtained during the course of the stud -suggests a predictive .markers] for response or disease stabilization, up to 15 additional subjects; with this tunior-j ioraarker'"sigtta$ui¾" will be enrolled.

[003.38] Detailed instructions for pharmacodynamic sample preparation and shipping will be provided, to the study sites in a separate Pharmacodynamic Laboratory Manual.

(0033*)} Pharmacodynamic studies may include investigation of the impact of target mutations (PI3K catalytic -and/or regulator;-' subunits) pre-existing in the subject's tumor on response, fluctuation of plasma levels of pathway-relevant proteins (e¾g., vascular, endothelial growth .factor Λ fVEGF-A], glucose, and insulin), drag-induced changes in phosphorylation of signal transduction proteins and lipids (e.g., pEGFR, pAKT. pERK, pGS . and PIP3), as well as assess ment of the contribution Of complementin genet ic changes in targe t modulators (e.g., PTE , RAS, e- ET, HER2, and L B- ^' l) on efficacy

Statistical Methods

f 00340] The co-primary efficacy .endpoints are: 1) ORR, defined as the proportion of subjects for whom the best response is a confirmed CR or confirmed PR, and 2) PESO, defined as- the proportion of subjects who survive and are progression free at least 183 days after the date of the first dose of study ding, Deienmfmtion of response and progression will b based on -evaluation per RECiST Version L I ,

ftH)341J Prior to amendment 3 (Part 1), the- study was designed to test the- following hypotheses:

ORR is≤ 5% and proportion with PFS6 is < 15%

H.v ORR is > 20¾ or proportion with PFS6 is > 3.0%

{00342[ Tlie sample size estimate of 71 subjects eva!uable per protocol is based on a single-arm, two-stage design by Sill and Yothers (2008) with a nominal -alpha of 0.07 and power of 90%,

1003431 Based on the stopping rule defined in the original protocol (2-stage design), the study met the futility criteria for tlie overall study population. As of amendment 3 (Part 2), the primary analysis population is changed to the subset of patients with only I prior line of treatmen for advancedtecurt ^' eHt endometrial cancer, and BGOG of 0 to 1 and the primary analysis of interest will be the estimate of co-primary endpotnts (G ^' RR and PFS6) with corresponding 90% confidence intervals.

[00344) if molecular profiling data obtained among the above subjects suggest a predictive mas-kerfs) for objective response or stable disease, n additional 15 subjects whose tumors express this bioraarker signature may be enrolled. A sample size of 15 ensures that if the true response rate is 20% or more then the probability of observing no response is less than 4 percent.

{00345} Secondary efficacy endpotnts of duration of response and median FFS will be estimated. Time -to-e vest analyses inc udin landmark es timates such as PFS6) will use Kaplan-Meier methods. Confidence intervals for proportions -will e - constructed using exaet methods.

Study Design

i 0.0352) This is a ffiuitieenter _* Phase i/:2, open-label, study of Compound A in combination with Ietrozoie (Ami I) . and Compound B in combination with Ietrozoie (Arm 2), in subjects with hormone receptor-positive (Eft-f and/or PGR*'}, HER2-negattve (HER2-) breast cancer whose disease i refractory So a nonsteroidal aromatase inhibitor. Subjects who had disease progression while receiving a nonsteroidal aromatase inhibitor for locally advanced or metastatic breast cancer or disease .recurrence; while receiving adjuvant treatment with a nonsteroidal ammatase inhibitor will be treated with either Compound A or Compound B in combination with letrozole as follows.

(00353) Treatment Arm 1 subjects will receive:

» Compound A (ablets, orally administered once daily (qd) and

« Letrozo!e tablets, orally administered qd, 30 minutes after Compound A.

{00354{ Treatment Arm 2 subjects will receive:

• Compound B capsules, orall administered twice daily (bid), with the first dose

administered in the morning and lite second dose 10-12 hours after the first (morning) dose.

♦ Letrozole tablets, orally administered qd, 30 minutes after the first (morning) dose of Compound B.

Phase 1

003551 Subjects will be alternately assigned to Arm I and Arm.2. A ^* 3*3 ^* dose-escalation ^' design w ill be employed to determine, the MTD of the Compound A tablet formulation in combination with letrozole and of the Com ^' pouftd B capsule formulation i combination with ietfoi'.ole. Subjects will receive the standard dose of 2.5 mg letrozole qd (i.e.,. there will be no. dose escalation of letrozole). Cohorts of subjects will be accrued in each arm to increasing doses of Compound A in combination with l.etrozole (Arm 1) or of Compound B in combination with letrozole (Arm 2) until more than 1 of 3 subjects or > 33% of 3 to 6 (or more) subjects at a . dose level experience, a. delimi ing toxicity (DLT) in the first 28 days of study treatment. Dose escalation in Ann 2 will not proceed beyond an Compound B dose of 50 mg bid (the MTD from single-agent Phase I Stud Compound B-OOl ), The _. single-agent MTD for the Compound A tablet formulation has not been determined.

[00356J If more than 1 of .3 subjects or > 33% of 3 to 6 (or more) subjects at a dose level, experience a DLT in the first 28 days of study treatment, this dose will be considered the maximum administered dose (MAD) for the treatment combination where the DLT occurs. Dose levels below the MAD will then be explored for safety and ioiembillly. The MTD in each arm will be defined based on six subjects. The decision to dose escalate w hki each treatment ami will be made by the Study Committee when ail .subjects in the current cohort have had the opportunity to complete, at least 28 days of study treatment. All available safety and PK data will be considered in the decision to dose escalate, de-escalate, or expand the current cohort, Phase 2

(00357} Once the MTD is determined in. Phase L subsequent subjects will be enrolled in Phase 2, As of Amendment 3, the doses for Phase 2 are 400 mg qd of Compound A (Arm 1) .and 50 mg bid . ^' of Compound B, both in conibii stioo with letrozole 2.5 rag qd.

(00358} li Ann 1, initial dose of Compound A was 200 mg in combination with leir zo!e 2.5 mg, 6 subjects were treated with no DLTs reported. The dose was escalated to Compound A 400 mg qd in combination with ietro¾oie :,5 mg, four patients were treated and no DLTs were reported in at least 66.6% of subjects treated at this dose level; dosing data will be ^' completed b August 201 Ϊ . Preliminary PK data has not shown any interactions between Compound A and letrozole, MTD will be determined as Compound A 400 mg in

combination with letroz le 2.5 mg. Phase 2 pari of Ann .1 will open once safety data of the 6 treated subjects in this dose level is complete,

[0O359| In Arrn 2, initial dose of Compound B was 30 rag bid in ^" combination with letroxole 2,5 mg. 3 subjects were treated with no DLTs reported. The dose was escalated to 50 mg bid. One of si subjects at this dose level (k combination with letrezole 2.5mg) experienced a DLT (grade 3 skin rash). I eiiminary PK data has not shown- any interactions between Compound B and Sctrozo!e. MTD s' determined as 50 nig bid of Compound. B in combination with letrozoie 2,5 mg. Phase 2 part of Ann 2 of die study is open for enrollment.

(00360} For each arm of Phase 2, a two-stage design will be used to evaluate the co- primary endpoints of ORR and PFS6. in each ami, approximate ty 50 subjects will be enrolled to obtain 48 evaiuahie subjects per protocol. Stage 1 will enroll 24 evaiuahie subjects in each, arm. If at least two subjects achieve an objective response (a confirmed PR or a confirmed €11} or at least four subjects are alive and progression free for at least ij months, then that ami will continue to Stage 2 until 48 evaiuahie subjects (including both stages ^' ) have been enrolled.

(00361} .Each- arm will be evaluated independently; no formal comparisons between arms are planned,.

|tl0362| hi each a m, tip to 10 subjects AVfaose tumors have a documented PI K3CA imitati n or molecular signature may be accrued to estimate th -ORR in subjects whose tumors have this molecular alteration.

[00363} Each subject ^' s course on study will consist of the following periods. Pre-Treatment Period

Safety

100373] Safety will be assessed by evaluation of adverse, events CAEs), vital signs, electrocardiogram (breast eaneerG), laboratory tests, and concomitant. medication. Adverse event seriousness, severity grade, and relationship to study treatment will be assessed by the investigator. Severity grade will be defined by the National Cancer Institute CTCAE v3.0.

Tumor Assessmea is

[00374] Tumor response will be assessed In Phase 1 a id Phase 2 asing Rbreast caneeriST Version 1 A (Eisenhauer et al. 2009): Subjects will be assessed using an Mill, or CT scan at screening, 8 weeks after the first dose of study treatment (Week 9 Day 1), and every 8 weeks thereafter until documented .radiographic progression, the initiation of other anticancer therapy, or death. Responses, will be confirmed by repeat assessments at least 4 weeks after the response criteria are met.

(0037S) Evaluation of tumor markers is not required in this study, if a subject has a tumor marker tha t is being followed and that has been shown to fee indicati ve of disease progression or response, it should: e documented at each, tumor assessment (at screening and during the study). However, changes of tumor markers will not be used for tumor response analysis.

Pharaiacokiiit ies

|0037<S| Blood samples for assessment of Compound A, Compound 8, aad !etrozole plasma concentrations, when given in combination, will be obtained at the time points during the study,

(00377] In addition, PK samples will be collected _* if possible, whenever a subject has a study treatment-related serious adverse event (SAE) and when, a increase in QTc intervals leads to changes in subject management.

FUarmacpdyuanics

{iji>378| Blood and tumor tissue samples (and -nontureor tissue · obtained at the same time as a prior tumor biopsy, if available) will be obtained from consented subjects for analysis of a variety of established and exploratory pharmacodynamic markers on a defined schedule throughout the study.

(00379 ^· ) Before Week 1 Day 1, a blood sample will be collected for hio arker analysis. On Week I Da I, before the first Compound A dose or the Convpoimd B morning dose, two blood samples will be collected: one ^' for plasma DNA genotyping and one for SNP analysis. In addition, blood samples for pharmacodynamic analysis will be collected at time points during the study.

(00380) Optional tumor- biopsies may be taken at time points during the study (total .sampling limit of up to three tumor biopsy time points). Procedures for tumor and nontumor tissue biopsies are readily available to the skilled practitioner.

Statistical Methods

fOOSSlJ Each arm will be ^■■ evaluated independently; no formal comparisons between anus are planned,

(00382) in Phase 1, no formal statistical tests are planned. Confidence intervals may be calculated tor selected safety -and exploratory variables.

)00383| For Phase 2, the co-primary efficacy endpomts for- each, arm are: 1) ORR, defined as the proportion of subjects for whom the best ^' response is a confirmed CR or confirmed PR, and 2} PFS6, defined as the proportion of subjects who. survi ve and are progression free at least 24 weeks after the date of the firs* dose of study drug. Determination of response and progression will be based on evaluation per libreasC caneerlST Version 1 ,1,

[00384} The study is designed to test the following hypotheses for each arm:

* HO: ORR is < 5% and proportion with PFS6 is < 1 ø%

* HA: ORR is > 20% or proportion with PFS6 is 30%

[00385.1 The sample size estimate of 48 subjects evaluable per protocol in. each arm s based on a two-stage design ^' by Sill and Yothers- (2008) with a nominal alpha of 0.07 and power of .90%.

[00386) For each, arm of 24 evaluable subjects in Stage 1. if at least two achieve an objective response or at least four are alive and progression .tree at 6 months (24 weeks) then the study will continue to Stage 2. Of the 48 total evaluable ^■ subjects, if at least six ^■" subjects achieve an objective response or at least nine subjects are alive and progression free at

6 raoaths, the null hypothesis will be rejected, and it will be inferred thai the true ORR is ^' > 5% or PFS6 is > 10%. Assuming that approximately 95% of enrolled subjects will be evaluable, approximately 50 subjects will be enrolled to ensure 4S evaluable subjects.

{003.871 Iff each arm. up. to 10 subjects ^' whose tumors have a documented PDGCA mutation or molecular signature may be accrued to estimate, the ORR in subjects whose tumors have this _, molecular alteration. A sample sixe of 10 assures that if the true response rate is 20% or snore, then the probability of observing no response is less than 12%.

[06388! Secondary efficacy endpoints of duration of response, median PFS, and CBR will be estimated.

[00389} Duration of response is defined as the time from first documented c onfirmed ■objective response to disease progression or death and will be analyzed using Kaplan-Meier methods for subjects with objective response. Median FFS {including landmark estimates such as PFS6) will use Kaplan-Meier methods. CBR is. defined as confirmed CR or confirmed PR at any time while the subject is on study treatment; or SI) for 24 weeks. CBR will be summarized ^' -using frequency counts and percentages. Two-sided exact (Case!la 1986) 90% confidence intervals may be computed for CBR.
