Introduction 
1.1 
Background 
The mechanisms underlying cancer are marked by complex aberrations that 
activate critical cellular signaling pathways in tumorigenesis.  Identifying 
actionable molecular aberrations has been critical to several major therapeutic 
advances in cancer medicine. Examples include BCR-ABL fusion in chronic 
myeloid leukemia (CML), epidermal growth factor (EGFR) mutations and EML4-
ALK fusion in non-small cell lung cancer, and BRAF mutations in melanoma.1-4  
The phosphatidylinositol 3-kinase/protein kinase-B/mammalian target of 
rapamycin (PI3K/AKT/mTOR) signaling cascade is one of the most important 
intracellular pathways, which is frequently activated in diverse cancers (Figure 
1).5,6 PI3K/AKT/mTOR signaling regulates cell proliferation, differentiation, 
cellular metabolism, and cytoskeletal reorganization leading to apoptosis and 
cancer cell survival. Activation of the PI3K/AKT/mTOR signaling pathway 
mediated through molecular aberrations such as loss of PTEN function is 
instrumental in promoting tumor development as well as resistance to anticancer 
therapies.7,8 Preclinical models and early clinical data in several tumor types 
suggested that loss of PTEN function can result in increased sensitivity to 
therapies targeting the PI3K/AKT/mTOR signaling pathway.5,9,10 It is conceivable 
that loss of PTEN function, which is a major negative regulator of the pathway, 
can be predictive, whereas simultaneous mutations in the mitogen-activated 
protein kinase (MAPK) and PI3K pathways may lead to therapeutic 
resistance.5,8,11-13, 27-29. 
 
The tumor suppressor gene PTEN (also known as MMAC, mutated in multiple 
advanced cancers) was initially observed independently by two groups in 1997 
on the 10q23 chromosomal region of PTEN, which was known to be deleted in 
many advanced cancers.14,15 PTEN is a lipid phosphatase that catalyzes the 
conversion of the second messenger PIP3 to PIP2 and thus reverses PI3K 
functionality in signal propagation (Figure 1).16 Moreover, it is now well 
established that PTEN has serine, threonine, and tyrosine phosphatase activity 

ECOG-ACRIN 
EAY131-N

for several protein substrates, resulting in its complex functions in cellular 
signaling.17 PTEN protein consists of 403 amino acids divided into functional 
domains, the N-terminal PIP2-binding domain (PBD), phosphatase domain, C2 
domain and C-terminal tail with two PEST (proline, glutamic acid, serine, 
threonine) domains, and a sequence governing protein-protein interactions 
(PDZ).18 These different PTEN domains are relevant to its tumor suppressor 
function due to the large diversity of tumor-associated mutations observed across 
all of its domains.19 The loss of PTEN function can be caused by various 
mechanisms including mutations, deletions, transcriptional silencing and 
epigenetic changes.20 Transcriptional repression and epigenetic silencing of 
PTEN typically occurs via gene promoter hypermethylation.21,22  
Mutations as well as loss of PTEN are found in various tumor types. The TCGA 
studies identified PTEN mutations in 63% of endometrial cancers, 30% of 
glioblastomas, 8% of cervical cancers, 7% of skin cancers as well as in other 
tumor types (cBioPortal for Cancer Genomics). The COSMIC database identified 
PTEN mutations in 39% of endometrial cancers, 14% of central nervous system 
tumors, 12% of skin cancers, 11% of colorectal cancers, 10% of prostate 
cancers, 5% of cervical cancers as well as in other tumor types (Figure 2) 
(COSMIC [Catalogue of Somatic Mutations in Cancer]). The complete loss of 
PTEN was also observed in a high number of cases of uterine (33%), renal 
(27%), salivary gland (20%), colorectal (18%), breast (13%), pancreatobiliary 
(13%) and prostate cancers (11%).23 Because of the numerous mechanisms 
underlying PTEN inactivation on genetic and epigenetic levels, accurate 
assessment of PTEN status in individual tumor samples remains challenging. 
 
Preclinical models demonstrated that PTEN function is an important regulator of 
G protein-coupled receptor signaling transmitted through PIK3CB. PTEN-
deficient tumors are critically dependent on PIK3CB activity and tumors with 
PIK3CB activation are sensitive to PIK3CB inhibitors.10,24 Notably, breast cancer 
cell lines with PTEN loss compared to those with PIK3CA mutations 
demonstrated resistance to treatment with mTOR complex 1 (mTORC1) targeted 
therapy.9 A complete loss of PTEN expression was found in 10% of heavily 
pretreated patients with diverse advanced solid tumors, and 23% of them

experienced a partial response or stable disease greater than or equal to 6 
months when treated with a PI3K/AKT/mTOR axis inhibitors.23 These findings 
suggest that matching patients with inhibitors based on PTEN aberrations merits 
further exploration.5 
GSK2636771 is a potent and selective inhibitor of phosphoinositide 3-kinase 
(PI3K) beta, which demonstrated activity in preclinical models with a loss of 
PTEN function.25 In addition, the first-in-human dose escalation study has been 
completed.25 Because PTEN function could be lost in various ways as noted 
above, MATCH will examine patients with complete PTEN loss of expression (by 
IHC) as well as those who retain PTEN expression by IHC but have a PTEN 
mutation or deletion by NGS. In the context of the NCI MATCH protocol, this is a 
phase II open label study for patients with PTEN deficient tumor as defined by 
PTEN mutations or deletion, but with retained PTEN staining on IHC. A separate 
MATCH subprotocol (EAY131-P) will investigate complete loss of PTEN 
expression by IHC in patients with or without mutations or deletions of PTEN by 
NGS. 
1.2 
GSK2636771 
1.2.1 
Non-clinical and clinical data 
GSK2636771 has been assessed in primary and secondary 
pharmacodynamic studies, as well as safety, pharmacology and 
toxicology studies. A summary of the available relevant non-clinical 
data is provided below. Study details and additional information can 
be found in the Investigator Brochure. 
1.2.2 
Non-clinical pharmacology 
GSK2636771 is a potent and selective inhibitor of phosphoinositide 3-
kinase (PI3K) beta with an apparent Ki (Kiapp) value of 0.89 nM with 
selectivity > 900-fold over PI3K alpha and gamma with Kiapp values 
of 819 and > 5000 nM, respectively, and 10-fold over PI3K delta 
(Kiapp of 8.6 nM). Among the other members of the PI3K superfamily 
tested, GSK2636771 was not inhibitory at concentrations > 10uM and 
demonstrated less than 30% inhibition against 294 additional kinases. 
GSK2636771 is an ATP competitive inhibitor of PI3K beta that is 
rapidly reversible and not time dependent and has a similar potency 
(within 2-fold) against three PI3K beta orthologs; mouse, rat and dog 
as compared to human PI3K beta.  
In phosphatase and tensin homolog (PTEN) mutant cell lines, but not 
wild-type PTEN lines, GSK2636771 inhibited cellular AKT 
phosphorylation in a concentration dependent manner. In the cell lines 
evaluated, the inhibition of AKT phosphorylation resulted in the 
inhibition of downstream PI3K/AKT signalling molecules in PTEN 
deficient, but not PTEN wild-type cell lines. GSK2636771 inhibited the 
anchorage independent cell growth of 87% of PTEN null tumor cell 
lines (13 out of 15 cell lines) but only 14% of PTEN wild-type (1 out of 
7).  
In mice bearing PC3 prostate carcinoma xenografts, single oral daily 
doses of GSK2636771 at 10, 30 and 100 mg/kg for 21 days resulted 
in stable disease with minimal tumor growth delay at 1 and 3 mg/kg. 

ECOG-ACRIN 
EAY131-N 
Cancer Research Group 
Version Date: February 6, 2017

In mice bearing PC3 prostate carcinoma or HCC70 breast carcinoma 
xenografts, oral doses of 3 or 10 mg/kg (PC-3) or 10 or 30 mg/kg 
(HCC70) GSK2636771 inhibited AKT phosphorylation in both tumor 
types (by up to 80%), in a dose-dependent manner. Inhibition of AKT 
phosphorylation was rapid and lasted for several hours after a single 
oral administration. In naïve mice, single oral daily doses of 100 
mg/kg GSK2636771 for four consecutive days did not affect fasting 
blood glucose and insulin levels. GSK2636771 showed significant 
anti-tumor activities in a PDX model of gastric cancer when 
administered alone or in combination with trametinib (GSK1120212, a 
potent and selective MEK inhibitor). In a combined cardiovascular, 
respiratory and neurobehavioral study in dogs, a single oral dose of 
300 mg/kg produced a reversible increase in mean arterial pressure 
(up to 11 mm Hg; up to 10%) from 2 to 8 hours post dose with a 
compensatory decrease in heart rate (up to 11 bpm; up to 12%) and 
decrease in cardiac contractility (up to 4.1% increase QA interval) 
during the same time period. The decrease in heart rate appears to be 
a baroreceptor-mediated reflex response to the increased arterial 
blood pressure, while the decrease in the measure of contractility may 
be attributed to the decrease in heart rate and a baroreceptor-
mediated change in autonomic nervous input into the heart. Doses of 
5 or 100 mg/kg did not produce any effect on arterial pressures or 
heart rate, and repeat doses up to 1000 mg/kg/day for 1 month did not 
produce any adverse effects on electrocardiogram (ECG) 
measurements. GSK2636771 did not produce acute neurobehavioral 
or respiratory effects in dogs following single doses up to 300 mg/kg. 
GSK2636771 minimally inhibited hERG tail current at the limit of 
solubility (20% inhibition at 70 ug/mL; 161 uM). In a rabbit left 
ventricular wedge assay, GSK2636771 exerted no torsadogenic 
potential up to the maximum concentration tested (13 ug/mL; 30 uM). 
Based on the weak hERG inhibition, absence of in vitro and in vivo 
effects on QTc and the high plasma protein binding in humans (99%), 
risk for QTc prolongation in humans is predicted to be low. 
1.2.3 
Non-clinical pharmacokinetics 
The pharmacokinetics and metabolism of GSK2636771 have been 
evaluated both in vitro and in vivo in several preclinical species. 
GSK2636771 exhibited moderate blood clearance in the mouse and 
rat (32 and 47% liver blood flow, respectively), but low in the dog and 
monkey (9 and 2% liver blood flow, respectively). The steady state 
volume of distribution (Vdss) was approximately three to four times 
larger than total body water in rats and mice, suggesting the potential 
for tissue distribution. However, in dogs and monkeys, the Vdss was 
equivalent to, or less than total body water. The half-life (t1/2) ranged 
from 1.37 to 5.88 hours. The oral bioavailability of GSK2636771 was 
high (≥ 94%). Protein binding was species dependent with the highest 
free fraction in mouse (35%) and the lowest free fraction in human 
(1.3%). GSK2636771 has high passive membrane permeability and 
was not a substrate for P-glycoprotein (Pgp). GSK2636771 appeared 
to minimally distribute to the brain in the rat (brain concentration was 
7% of blood concentration following a 1 hour intravenous infusion of 2 
mg/kg). 

ECOG-ACRIN 
EAY131-N 
Cancer Research Group 
Version Date: February 6, 2017 
9 
GSK2363771 had low intrinsic clearance in hepatic microsomes and 
hepatocytes of all species evaluated (i.e. rat, dog and human). In vitro 
and in vivo (rat), acyl glucuronidation was the major metabolic route 
for GSK2636771. However, GSK2636771 was the only detected 
component in rat blood. The major route of elimination in the rat was 
via the feces. The absorbed dose was eliminated primarily in the bile 
(the acyl glucuronide metabolite was the major component). 
GSK2636771 did not inhibit the major drug metabolizing cytochrome 
P450 (CYP450) enzymes including CYP3A4, and was not a time or 
metabolism dependent inhibitor of CYP3A4. GSK2636771 did not 
inhibit the drug transporters Pgp, breast cancer resistance protein 
(BCRP), organic anion transport polypeptide (OATP) 1B1 or 
OATP1B3. Therefore, the risk of GSK2636771 functioning as a 
perpetrator of drug interactions appears low. 
1.2.4 
Non-clinical toxicology and safety pharmacology 
The systemic toxicity of GSK2636771 has been evaluated in rats and 
dogs. Genotoxicity studies have also been conducted. The principal 
dose-limiting toxicities seen in animal toxicology studies conducted 
with GSK2636771 were kidney and gastrointestinal effects. There was 
a dose dependent increase in kidney tubular basophilia at ≥ 100 
mg/kg/day in rats with single cell and/or tubular necrosis in rats at 
1000 mg/kg/day and tubular degeneration/regeneration in dogs at 
1000 mg/kg/day. In rats, these findings correlated with increased 
mean kidney weights, decreased serum potassium, and increased 
mean serum urea. Urinary markers of kidney injury increased in rats 
and included KM1C, lipocalin-2, clusterin, RPAC at ≥ 100 mg/kg/day 
and urinary albumin, total protein, NAG, osteopontin, and alpha GST 
at 1000 mg/kg/day. Decreased body weight gain and food 
consumption and focal erosion and ulceration occurred in rat 
stomachs at 1000 mg/kg/day. The increased WBC counts in female 
rats at 1000 mg/kg/day is likely related to inflammation due to the 
kidney and gastrointestinal lesions. Increased heart weight and 
intramural coronary artery hypertrophy without ECG effects were 
observed in 1 male dog given 1000 mg/kg/day. A single dose of 300 
mg/kg produced a reversible increase in mean arterial pressure, 
decreased heart rate and decreased cardiac contractility. Additional 
adverse findings in animals given 1000 mg/kg/day were present in 
liver, stomach, hematopoietic and reproductive systems. In dogs, 
there was minimal to mild single cell hepatocellular necrosis with 
increased serum ALT, GLDH and AST. Lymphoid necrosis occurred 
in spleen, lymph nodes, and GALT of dogs, and rats had decreased 
thymus weights. Spermatocyte depletion was observed in rats (also at 
100 mg/kg/day) and dogs. In general, these findings were consistent 
with the expression and function of PI3 kinase. Based on the weak 
hERG inhibition, absence of in vitro and in vivo effects on QTc and the 
high plasma protein binding in humans (99%), the risk for QTc 
prolongation in humans is predicted to be low. In addition, 
GSK2636771 has a low genotoxic risk to humans. The kidney, 
gastrointestinal and liver effects are clinically monitorable and 
manageable, and generally recovered within 2 weeks off-treatment. In 
the 4 week rat study, the no observed adverse effect level (NOAEL) 

ECOG-ACRIN 
EAY131-N 
Cancer Research Group 
Version Date: February 6, 2017 
10 
was 10 mg/kg/day [gender averaged AUC0-t 7.08 ug.h/mL, Cmax 
1.83 ug/mL, Day 28 values]. The NOAEL in the 4 week dog study was 
100 mg/kg/day [gender averaged AUC0-t 225 ug.h/mL, Cmax 38.8 
ug/mL, Day 28 values]. 
1.3 
Supporting Preliminary Data  
1.3.1 
Clinical Data 
To date, the administration of GSK2636771 has been limited to 53 
subjects with PTEN deficient tumors as determined by 
immunohistochemistry (IHC) analysis who were enrolled in the FIM 
study P3B115717.25 The dose escalation part of the study has 
completed, and is now in an expansion phase enrolling patients with 
several tumor types with PTEN deficiency. Doses of GSK2636771 
evaluated have ranged from 25 mg to 500 mg once daily. The 
maximum tolerated dose (MTD) has been defined as 400 mg orally 
once daily.  
1.3.2 
Safety 
Dose limiting toxicities (DLTs) observed were hypophosphatemia and 
hypocalcemia. Dose-limiting toxicity (DLT) of hypophosphatemia was 
identified at 500 mg daily dose level, occurring in 3 of 4 subjects, and 
resulting in dose reductions and or discontinuations. 
Hypophosphatemia improved upon discontinuation of GSK2636771. 
The mechanism(s) of hypophosphatemia is under investigation. The 
most frequent adverse events (AEs) with GSK2636771 were Grade 1 
or Grade 2 gastrointestinal (GI) toxicities, with the most frequently 
reported AEs being diarrhea (43%), nausea (43%), fatigue (28%), 
vomiting (34%), abdominal pain (26%), decreased appetite (23%), 
anemia (23%), constipation (19%), headache (17%), hypokalemia 
(15%), Rash (15%), cough (13%), dyspnea (11%), edema peripheral 
(13%), hypocalcemia (13%), hypophosphatemia (11%), and urinary 
tract infection (13%). 
1.3.3 
Pharmacokinetics 
Preliminary pharmacokinetics (PK) results from study P3B115717 
indicate that GSK2636771 is absorbed orally with a median time to 
achieve the peak blood concentration (tmax) of 4 to 5 hrs after single 
doses of 25 to 500 mg. The median half-life of GSK2636771 ranged 
from 17.1 to 38.6 hrs across the dose range of 25 mg to 500 mg once 
daily. Mean maximum observed concentration (Cmax) and area under 
the concentration-time curve from zero (pre-dose) to 24 hrs (AUC(0-
24)) values on Day 22 were greater than the mean values observed 
after a single dose, demonstrating that GSK2636771 accumulated in 
plasma after repeated doses.

There are limited data available to assess the clinical activity of 
GSK2636771. In the FTIH study P3B115717 in patients with PTEN 
deficiency as determined by IHC, one subject with mCRPC who 
received 200 mg GSK2636771 once daily had a partial response (PR) 
per RECIST. There were 16 subjects (with various solid tumors) with 
stable disease and 8 subjects (with various solid tumors) who 
continued treatment for at least 6 months.

Selection of Patients 
Each of the criteria in the checklist that follows must be met, along with the eligibility in 
the MATCH Master Protocol, in order for a patient to be considered eligible for this 
study. Use the checklist to confirm a patient’s eligibility. For each patient, this checklist 
must be photocopied, completed and maintained in the patient’s chart.  
In calculating days of tests and measurements, the day a test or measurement is 
done is considered Day 0. Therefore, if a test is done on a Monday, the Monday 
four weeks later would be considered Day 28.

Each cycle of therapy will be 28 days and there will not be any breaks between 
dosing cycles. Patients must meet the following criteria in order to proceed with 
the next cycle of treatment: 
• 
ANC ≥ 1,000/μL 
• 
Platelets ≥ 75,000/μL 
• 
Hemoglobin ≥ 9 g/dL 
• 
Phosphorous, magnesium, potassium, and calcium (corrected for albumin) 
must either be within normal range for labs or no worse than grade 2. 
Supplementations may be used to keep within these ranges.  
• 
Serum creatinine must be ≤ 1.5 x ULN or 24-hour creatinine clearance of  
≥ 50 mL/min.  
Please refer to Section 3.4 for dose modifications. Within cycle toxicity that meets 
grade 3 or 4 criteria, will necessitate holding of the drug until the toxicity are 
improved to grade 1 or baseline, unless otherwise specified in the protocol. 
Repeat cycles until progression.

Dose Modifications 
All toxicity grades below are described using the NCI Common Terminology 
Criteria for Adverse Events (CTCAE) version 4.0. 
All appropriate treatment areas should have access to a copy of the CTCAE 
version 4.0. A copy of the CTCAE version 4.0 can be downloaded from the 
CTEP website (http://ctep.cancer.gov). 
GSK2636771 will be administered on an oral, daily, continuous administration 
schedule. The starting dose of the drug will be 400mg (four 100 mg capsules), 
once daily which was deemed the maximum tolerated phase II dose from the 
company sponsored phase I study. 
Each cycle of therapy will be 28 days and there will not be any scheduled breaks 
between dosing cycles. Patients must meet the following criteria in order to 
proceed with the next cycle of treatment: 
• 
ANC ≥ 1,000/μL 
• 
Platelets ≥ 75,000/μL 
• 
Hemoglobin ≥ 9 g/dL 
• 
Phosphorous, magnesium, potassium, and calcium (corrected for albumin) 
must either be within normal range for labs or no worse than grade 2. 
Supplementations may be used to keep within these ranges.  
• 
Serum creatinine must be ≤ 1.5 x ULN or 24-hour creatinine clearance of  
≥ 50 mL/min.  
At the beginning of a cycle, patients experiencing any toxicity that meets 
definition of grade 3 or 4 toxicity will have the study drug held until resolution of 
symptoms to grade 1 or baseline, unless otherwise specified in the protocol. 
Within cycle toxicity that meets grade 3 or 4 criteria, will necessitate holding of 
the drug until the toxicity are improved to grade 1 or baseline, unless otherwise 
specified in the protocol. In general, except as directed for specific examples in 
the following tables, if there is need to interrupt dosing for grade 3/4 toxicity, then 
there will be a dose reduction as per the table below, once toxicity improved to 
grade 1 or baseline. Dose may be suspended for up to 2 weeks due to toxicity. If 
treatment held for laboratory abnormality; recheck labs in one week. 
GSK2636771 will not be re-escalated once dose reduced. 
For diarrhea, nausea and vomiting, optimal supportive care should be initiated 
prior to dose reduction. If symptoms persist despite maximal supportive care, or 
at investigator discretion, doses may be reduced per criteria below. Suspend 
GSK2636771 for grade 3 or 4 symptoms and hold until resolved to grade 1 or 
baseline, unless otherwise specified in the protocol.

All supportive measures consistent with optimal patient care will be given 
throughout the study. 
Diarrhea, nausea and vomiting have all been reported with GSK2636771. 
Supportive measures with anti-diarrheals and anti-emetics are recommended per 
investigator discretion or local institutional guidelines for emergence of treatment 
related symptoms.  
GSK2636771 may enhance anti-platelet activity of agents that are irreversible or 
that act through platelet purinergic receptors. Any need for starting anti-platelet 
therapy in a patient enrolled to this arm will have to be evaluated by the 
subprotocol chair. Although aspirin does not act at the purinergic receptor, 
caution is recommended when GSK2636771 and aspirin are used concomitantly.

B. Albumin, alkaline phosphatase, total bilirubin, bicarbonate, BUN, calcium, creatinine, glucose, phosphorus, potassium, SGOT[AST], SGPT[ALT], 
sodium, magnesium and serum tumor markers (including LDH, PSA if appropriate).  For eligibility purposes, participants with creatinine levels 
above institutional normal, Cockcroft-Gault will be used to calculate creatinine clearance. CBC w/diff, platelets and serum chemistries should be 
performed on cycle 1, day 1 (or up to 7 days prior), and at the start of each subsequent cycle (up to 3 days before start of new cycle). CBC with 
differential will be performed more frequently in patients with grade 4 neutropenia or thrombocytopenia until resolution to ≤ grade 3. CBC and 
serum chemistries are only required in follow-up until values return to pre-treatment levels or until progressive disease. 
C. Blood pregnancy test (women of childbearing potential) required prior to beginning treatment. 
D. Disease measurements are repeated every 2 cycles for years the first 26 cycles, and every 3 cycles thereafter until PD or start of another MATCH 
treatment step. The baseline evaluation should be performed as closely as possible to the beginning of treatment and never more than 6 weeks 
before registration to treatment step. For multiple myeloma patients, please refer to Section 6.4 of the MATCH Master Protocol for additional

information on myeloma response criteria and the required disease assessments. Documentation (radiologic) must be provided for patients 
removed from study for progressive disease. 
E. Additional blood specimens and/or biopsies are to be submitted from consenting patients per the MATCH Master Protocol. Submit at the 
following time points, as applicable: 
• 
Blood specimens are to be submitted at the end of Cycle 2 (prior to start of Cycle 3 treatment). If patient progresses or treatment is 
discontinued prior to Cycle 3, collect the blood at that time instead.  See Section 9.3.2.3 of MATCH Master Protocol. On-treatment kits for 
blood sample collections will be automatically shipped to sites upon registration to the treatment step. 
• 
Screening biopsies for additional aMOI assessments after registration to appropriate screening step, if applicable (Step 2 or Step 4). 
• 
At end of all MATCH study treatments, blood specimens and/or research biopsy after consent and registration to Step 8 
Please refer to Section 4 of the MATCH Master Protocol to determine whether the patient proceeds to the next screening step or to 
follow-up (with a potential end of treatment biopsy for research purposes on Step 8). Samples are to be submitted as outlined in 
Section 9 of the MATCH Master Protocol. To order Step 2/4 Screening or Step 8 kits, complete the EAY131 Collection and Shipping Kit 
Order Form (See Appendix XII of the MATCH Master Protocol) and fax to 713-563-6506. 
F. Every 3 months if patient is < 2 years from study entry, and every 6 months for year 3. Toxicity assessments and radiologic evaluations are not 
required to be done during Follow Up if progression has been previously reported; however if an adverse event occurs post treatment that meets 
the SAE reporting requirements, it still must be reported via CTEP-AERS, even if progression has occurred. 
G. Site personnel should evaluate for toxicity and discuss treatment compliance with the patient in order to ensure the medication is taken correctly; 
this evaluation may be conducted by telephone or in person. The Toxicity Assessment is not required prior to Cycle 1, but is required every 
subsequent cycle. 
H. The pill calendar will be collected at the end of every cycle. The Pill Count/Diary is not required prior to Cycle 1, but is required every subsequent

Drug Formulation and Procurement 
This information has been prepared by the ECOG-ACRIN Pharmacy and Nursing 
Committees. 
Availability 
NO STARTER SUPPLIES MAY BE ORDERED. Subjects must be enrolled and assigned 
to the treatment subprotocol prior to submitting the clinical drug request to PMB. 
Drug Ordering: NCI supplied agents may be requested by the Principal Investigator (or 
their authorized designees) at each participating institution. Pharmaceutical 
Management Branch (PMB) policy requires that drug be shipped directly to the institution 
where the patient is to be treated. PMB does not permit the transfer of agents between 
institutions (unless prior approval from PMB is obtained – see general information) The 
CTEP-assigned protocol number must be used for ordering all CTEP-supplied 
investigational agents.  The responsible investigator at each participating institution must 
be registered with CTEP, DCTD through an annual submission of FDA Form 1572 
(Statement of Investigator), Curriculum Vitae, Supplemental Investigator Data Form 
(IDF), and Financial Disclosure Form (FDF).  If there are several participating 
investigators at one institution, CTEP-supplied investigational agents for the study 
should be ordered under the name of one lead investigator at that institution. 
Active CTEP-registered investigators and investigator-designated shipping designees 
and ordering designees can submit agent requests through the PMB Online Agent Order 
Processing (OAOP) application (https://eapps-ctep.nci.nih.gov/OAOP/pages/login.jspx).  
Access to OAOP requires the establishment of a CTEP Identity and Access 
Management (IAM) account (https://eapps-ctep.nci.nih.gov/iam/) and the maintenance of 
an “active” account status and a “current” password..  
NCI Supplied Agent(s) – General Information 
Questions about drug orders, transfers, returns, or accountability should be 
addressed to the PMB by calling 240-276-6575 Monday through Friday between 
8:30 AM and 4:30 PM Eastern Time or email PMBAfterHours@mail.nih.gov 
anytime. 
Drug Returns: All undispensed drug supplies should be returned to the PMB. When it is 
necessary to return study drug (e.g., sealed bottles remaining when PMB sends a stock 
recovery letter), investigators should return the study drug to the PMB using the NCI 
Return Agent Form available on the NCI home page (http://ctep.cancer.gov).  
Drug Accountability: The investigator, or a responsible party designated by the 
investigator, must maintain a careful record of the receipt, disposition, and return of 
agent received from the PMB using the NCI Investigational Agent Accountability Record 
Form for Oral Agents available on the NCI home page (http://ctep.cancer.gov).  Maintain 
separate NCI Investigational Agent Accountability Records for each agent, strength, 
formulation and ordering investigator. 
Investigator Brochure Availability: The current versions of the IBs for PMB-supplied 
agents will be accessible to site investigators and research staff through the PMB Online 
Agent Order Processing (OAOP) application.  Access to OAOP requires the 
establishment of a CTEP Identity and Access Management (IAM) account and the 
maintenance of an “active” account status and a “current” password.  Questions about IB 
access may be directed to the PMB IB coordinator at IBCoordinator@mail.nih.gov

5.1 
GSK2636771 (NSC 781258) 
5.1.1 
Other Names:  
GSK2636771B where B denotes the tris (hydroxymethyl) 
aminomethane salt 
5.1.2 
Classification: 
Phosphoinositide 3-kinase beta (PI3Kβ) inhibitor 
5.1.3 
Mode of Action: 
GSK2636771 is a potent, orally bioavailable, adenosine triphosphate 
(ATP) competitive, selective inhibitor of phosphoinositide 3-kinase 
beta (PI3Kβ) 
5.1.4 
Storage and Stability: 
Storage: Store at room temperature up to 30° C (86° F). 
Stability: Shelf life studies are ongoing. If needed, sites may 
repackage capsules in pharmacy bottles and assign a 30-day 
expiration date. 
If a storage temperature excursion is identified, promptly return 
GSK2636771 to room temperature and quarantine the supplies.  
Provide a detailed report of the excursion (including documentation of 
temperature monitoring and duration of the excursion) to 
PMBAfterHours@mail.nih.gov for determination of suitability. 
5.1.5 
Dose Specifics: 
GSK2636771 will be supplied in 100mg capsules. Starting dose will 
be 400 mg (4 x 100mg capsules) once daily for 28 days per cycle. 
Dose reductions will be to 300mg and 200mg. 
5.1.6 
Preparation: 
GlaxoSmithKline supplies and the PMB/CTEP/DCTD distributes 
GSK2636771 as size 0, opaque pink 100 mg capsules (free acid 
equivalent). Excipients include microcrystalline cellulose, 
croscarmellose sodium and sodium stearyl fumarate. The capsule 
shell contains gelatin, titanium dioxide (E171) and red iron oxide 
(E172)). 
Capsules are packaged in high density polyethylene bottles with 
induction seal liners and child-resistant caps. Each bottle contains 35 
capsules.  
5.1.7 
Route of Administration: 
Oral. Take at least 1 hour before or 2 hours after a meal with 200 mL 
water (about 7 ounces). 
5.1.8 
Incompatibilities: 
GSK2636711 is highly protein bound (99%) in humans. Use caution in 
patients who are receiving concomitant medications that are also 
highly protein-bound.

In vitro studies demonstrate that GSK2636711 is not a substrate for 
CYP450 enzymes or efflux transporter, P-glycoprotein (P-gp). It is 
primarily eliminated by acyl glucuronidation via unspecified UGT 
isozymes. Potent inhibitors and inducers of UGT may alter 
GSK2636711 exposure. 
Studies conducted in vitro show that GSK2636711 is not an inhibitor 
of CYP 450 enzymes or an inhibitor of transporters P-gp, breast 
cancer resistant protein (BCRP) and OATP1B1 and OATP1B3. 
GSK2636771 is a weak in vitro inhibitor of OAT1, OAT3 and OCT2; 
however, the interaction risk appears to be low at clinical 
concentrations. 
In vitro studies show that GSK2636711 does not activate the 
pregnane X receptor (PXR) and theoretically has a low potential to 
induce CYP450 isozymes. 
5.1.9 
Side Effects: 
See CAEPR in Section 3.3  
5.1.10 
Nursing/Patient Implications: 
GSK2636771 may enhance antiplatelet activity of agents that are 
irreversible (aspirin) or that act through platelet purinergic receptors 
(e.g. clopidogrel, ticlopidine, prasugrel). Avoid concomitant use of 
GSK2636771 in patients taking these anti-platelet agents or in 
patients who have a history of congenital platelet function defects.

Appendix III 
 
Patient Drug Information Handout and Wallet Card 
Information for Patients, Their Caregivers and Non-Study Healthcare Team on Possible 
Interactions with Other Drugs and Herbal Supplements 
The patient ____________________________ is enrolled on a clinical trial using the 
experimental study drug, GSK2636771.  This clinical trial is sponsored by the National Cancer 
Institute.  This form is addressed to the patient, but includes important information for others who 
care for this patient.  
These are the things that you as a healthcare provider need to know: 
GSK2636771 has the following qualities: 
• 
Is highly protein-bound and may prevent other drugs from binding to blood protein. Patients 
receiving other medications that are also highly protein bound may need to be monitored more 
frequently. 
• 
Is primarily broken down by UGT enzymes and may be affected by other drugs that strongly 
inhibit or induce these enzymes.   
• 
May enhance the antiplatelet activity of agents that are irreversible (aspirin) or that act through 
platelet purinergic receptors like clopidogrel, ticlopidine and prasugrel 
To the patient: Take this paper with you to your medical appointments and keep the 
attached information card in your wallet.   
GSK2636771 may interact with other drugs which can cause side effects. For this reason, it is 
very important to tell your study doctors of any medicines you are taking before you enroll onto 
this clinical trial.  It is also very important to tell your doctors if you stop taking any regular 
medicines, or if you start taking a new medicine while you take part in this study.  When you talk 
about your current medications with your doctors, include medicine you buy without a prescription 
(over-the-counter remedy), or any herbal supplements such as St. John’s Wort.  It is helpful to 
bring your medication bottles or an updated medication list with you. 
Many health care providers can write prescriptions.  You must tell all of your health care providers 
(doctors, physician assistants, nurse practitioners, pharmacists) you are taking part in a clinical 
trial.  
These are the things that you and they need to know:  
GSK2636771 must be used very carefully with other medicines that are highly protein-bound or 
avoided with other medicines that affect platelets to thin your blood, including aspirin. Before you 
enroll onto the clinical trial, your study doctor will work with your regular health care providers to 
review any medicines and herbal supplements that are considered highly protein-bound or affect 
platelet activity. 
• 
Please be very careful!  Over-the-counter drugs (including herbal supplements) may contain 
ingredients that could interact with your study drug.  Speak to your doctors or pharmacist to 
determine if there could be any side effects.  
• 
Patients receiving other medications that are also highly protein bound may need to be 
monitored more frequently. 
• 
Your regular health care provider should check a frequently updated medical reference or call

STUDY DRUG INFORMATION WALLET CARD 
You are enrolled on a clinical trial using the experimental 
study drug GSK2636771.  This clinical trial is sponsored 
by the NCI.  GSK2636771 may interact with drugs that are 
strong inhibitors or inducers of UGT, highly protein-bound 
or affect platelet activity, like aspirin.  Because of this, it is 
very important to: 
➢ Tell your doctors if you stop taking any medicines or if 
you start taking any new medicines. 
➢ Tell all of your health care providers (doctors, physician 
assistants, nurse practitioners, or pharmacists) that you 
are taking part in a clinical trial. 
➢ Check with your doctor or pharmacist whenever you 
need to use an over-the-counter medicine or herbal 
supplement. 
➢ GSK2636771 may interact with drugs that affect UGT 
liver enzymes, is highly-protein bound and may interact 
with other drugs that are bound to blood protein or 
drugs that affect platelets 
to thin blood. It must be used very carefully with 
other medicines that are also highly-protein bound 
or avoided with other medicines that affect platelet 
activity.  
➢ Before you enroll onto the clinical trial, your study 
doctor will work with your regular health care 
providers to review any medicines and herbal 
supplements that are considered strong inhibitors 
or inducers of UGT, highly protein-bound or affect 
platelet activity, like aspirin, clopidogrel, ticlopidine, 
and prasugrel. 
➢ Before prescribing new medicines, your regular 
health care providers should go to a frequently-
updated medical reference for a list of drugs to 
avoid, or contact your study doctor.   
➢ Your study doctor’s name is 
_____________________________ and can be 
contacted at
