Section 5.1.1 LY3023414 or Placebo
Patients should take the morning and evening doses of LY3023414 approximately 12 hours apart 
(preferably within a 10- to 14-hour range).  Patients should not consume food for approximately 
1 hour before taking the dose of LY3023414 or matching placebo and should remain in a fasting 
state for 1 hour post-dose.  LY3023414 or matching placebo should be taken with a glass of 
water at approximately the same time each day.  LY3023414 or matching placebo can be taken 
with or without food.  Patients should swallow the capsules as a whole and should not chew or 
crush them.  
Section 5.1.2 Enzalutamide
Enzalutamide will be self-administered by the patient.  Enzalutamide will be taken together with 
one of the two daily doses of LY3023414 or matching placebo.  Therefore, patients should not 
consume food for approximately 1 hour before taking the dose of enzalutamide and should 
remain in a fasting state for 1 hour post-dose. Enzalutamide can be taken with or without food  
Enzalutamide capsules should be swallowed whole.  Patients should not chew, dissolve, or crush 
them.  
Section 5.7 Pharmacogenetic (PGx) Assessment
The PGx sample is part of the biomarker sample.  Therefore, there is no separate kit for PGx 
samples.  Samples will only be used for investigations related to disease and drug or class of 
drugs under study in the context of this clinical program.
Section 10.2 Sample Size Consideration and Synopsis
PASS14 PASS13 Version (copyright 2015 2014) was used to calculate sample size.
Two interim analyses were planned at approximately 39% information rate and 82% 
information rate.  Approximately 0% of total type I error and 20% of total type II error were 
spent at the first interim.  The first interim analysis is planned to be conducted when a total of 
36 PFS events are observed.  Approximately 20% of total type I error and 0% of total type II 
error were spent at the second interim.  The second interim analysis is planned to be 
conducted when a total of 75 PFS events are observed.
The interim analysis is planned at approximately 75% information rate, with approximately 40% 
of total type I error and 0% of total type II error spent at the interim.  The interim analysis will be 
conducted when a total of 70 PFS events are observed.
Section 10.6.1 Final Analysis
The final analysis of the study will be triggered when 92 96 patients have had an event (disease 
progression or all cause death).

Section 10.6.2 Planned Interim Analysis
The first interim analysis will be conducted when a total of 36 PFS events are observed for 
futility assessment. The one sided p-value of 0.774 will be used as the boundary to assess the 
efficacy of enzalutamide plus LY3023414 versus enzalutamide plus placebo for the first 
interim analysis. If the P-value is more than 0.774, the study will be terminated for futility. 
The second interim analysis will be conducted when a total of 75 PFS events are observed. 
One-sided p-value of 0.042 will be used as the boundary to assess the efficacy of enzalutamide 
plus LY3023414 versus enzalutamide plus placebo for the second interim analysis. 
One-sided p-value of 0.2 will be used as the boundary to assess the efficacy of enzalutamide 
plus LY3023414 versus enzalutamide plus placebo in the final analysis.
Interim analysis will be conducted when a total of 70 PFS events are observed.  One-sided p-
value of 0.077 will be used as the boundary to access the efficacy of enzalutamide plus 
LY3023414 versus enzalutamide plus placebo during the interim analysis.  One-sided p-value of 
0.195 will be used as the boundary to access the efficacy of enzalutamide plus LY3023414 
versus enzalutamide plus placebo in the final analysis.
Schedule of Assessments
Footnote f - PT/INR will only need to be repeated if abnormal at baseline or if clinically 
indicated.  Patients requiring the initiation of an anti-coagulation therapy during study treatment 
should have their coagulation test performed on a weekly basis.
Footnote s - The PGx sample should be collected C1D1. If the sample is not able to be collected 
C1D1, it can be collected anytime during C1 or C2. The PGx sample is part of the biomarker 
sample and does not require a separate kit.

Objectives:
Exploratory Objective
The exploratory objective of this study is:

To collect blood and archival tissue for exploratory studies to identify potential 
biomarkers predictive of clinical efficacy of study treatment and disease 
progression in this patient population.
Study Design:
This is a double-blinded, placebo-controlled, randomized Phase II study of the combination 
of enzalutamide plus LY3023414 versus enzalutamide plus placebo in medically or 
surgically castrated men with mCRPC who have shown disease progression on abiraterone.  
Cycles will be 28 days in length.  Patients will be treated until disease progression 
(radiographic or PCWG2 symptomatic progression), or until they develop an unacceptable 
adverse event (AE) requiring discontinuation of the drug, or patient/physician choice.  
Patients with PSA progression are allowed and encouraged to continue treatment until 
clinical (symptomatic or radiographic) progression.
Lead-In (Part A)
A lead-in (Part A) of approximately 6-12 patients will be conducted prior to the randomized 
Phase II portion of the study to assess safety, tolerability, and available PK data for potential 
PK interaction.  Prior to starting this combination therapy on Cycle 1 Day 1, patients in Part 
A will be given single agent LY3023414 200 mg every 12 hours (BID) during the initial 
week (called Week -1) to assess LY3023414 PKs at a steady state (Section 5.6) on Day -1 
(last day of that Week -1).
Double-blinded, Placebo-Controlled Randomized Study (Part B)
After dose is established in Part A, a total of 132 patients will be randomized in a 1:1 ratio to 
enzalutamide 160 mg orally QD in combination with LY3023414 200 mg or matching 
placebo orally BID (Part B).  Randomization will be stratified based on two factors: 1) the 
presence or absence of visceral disease (i.e. non-lymph node soft tissue disease), and 2) if 
patients previously received chemotherapy in the hormone-sensitive setting when 
commencing androgen deprivation therapy (ADT).  
Study Drugs, 
Doses, and Modes 
of Administration:
Enzalutamide 160 mg will be administered orally QD.
LY3023414 200 mg or matching placebo will be administered orally BID.
Inclusion Criteria:
1.
Histologically or cytologically confirmed adenocarcinoma of the prostate.
2.
Metastatic disease documented by positive bone scan or metastatic lesions on CT, MRI.  
If lymph node metastasis is the only evidence of metastasis, it must be ≥ 2 cm in 
diameter.
3.
Prostate cancer progression documented by PSA and/or radiographic progression 
according to PCWG2 (Appendix F).  PSA levels must have a starting value of at least 
2.0 ng/mL that have increased on 3 occasions obtained a minimum of 1 week apart.
4.
Prior abiraterone treatment completed at least 2 weeks prior to Cycle 1 Day 1.  Patient 
must have failed prior abiraterone treatment to be eligible.
5.
If patient has previously been treated with RA-223 dichloride, treatment must be 
completed at least 4 weeks prior to Cycle 1 Day 1 (minimum 4 week wash out period).

GU 115/I6A-MC-CBBD PROTOCOL SYNOPSIS
Correlative 
Testing:
Blood and archival tumor samples will be collected to evaluate biomarker including but not 
limited to PI3K pathway components.  Tumor and blood samples may be analyzed to 
explore potential biomarkers (e.g. gene signature[s]) predictive for response to study 
treatment. Mutational status, copy number variations, and/or protein products of cancer-
related genes (including, but not limited to, PIK3CA, PTEN, or RAS and AR-V7) may be 
analyzed at a laboratory designated by the sponsor.
Statistical 
Methodology:
Determination of sample size:
Sample size considerations for the randomized portion of the study (Part B) are based on the 
primary endpoint of PFS and one interim analysis of efficacy.  The median PFS in the 
control arm of enzalutamide is estimated to be 4 months (Schrader et al. 2014) and a 
clinically meaningful hazard ratio (HR) is taken to be 0.7, equating to a median PFS in the 
enzalutamide plus LY3023414 arm of 5.7 months.  Based on a 16-month accrual period (3 
months ramp up plus 13 months full recruitment), a minimum of 9 months follow-up after 
the last patient has been randomized, and a lost to follow-up/non-compliance rate of no more 
than 10%, a total of 132 patients will be randomized in a 1:1 ratio between the two treatment 
arms. With a total of 92 events, the study will have at least 80% power to test the primary 
hypothesis using a one-sided, log rank test at the 0.20 significance level.
Two interim analyses were planned at approximately 39% information rate and 82% 
information rate. Approximately 0% of total type I error and 20% of total type II error were 
spent at the first interim.  The first interim analysis is planned to be conducted when a total 
of 36 PFS events are observed.  Approximately 20% of total type I error and 0% of total type 
II error were spent at the second interim. The second interim analysis is planned to be 
conducted when a total of 75 PFS events are observed.

INTRODUCTION
1.1
Background
Prostate cancer is the most commonly diagnosed cancer in men with an estimated 233,000 new 
cases in the United States in 2014 and is the second-leading cause of cancer death in men with an 
estimated 29,480 deaths in 2014 (American Cancer Society 2014).  The majority of patients are 
diagnosed with and treated for localized disease.  However, a percentage of patients do present 
with metastatic disease at diagnosis, and others develop metastatic disease after completing 
definitive treatment.  Androgen deprivation therapy (ADT) is the cornerstone of treatment for 
metastatic prostate cancer; the goal of this line of therapy is primarily palliative and for 
prolongation of survival, but not as a cure.  Initial androgen deprivation is typically achieved 
with bilateral orchiectomy (surgical castration) or luteinizing hormone-releasing hormone 
(LHRH) therapy.  
In 2014, it was shown that use of docetaxel at the time of ADT for metastatic hormone-sensitive 
prostate cancer prolonged overall survival (OS) by 13 months (Sweeney et al. 2014).  Patients 
treated with androgen deprivation (medical or surgical castration) who develop disease 
progression in the presence of adequately depressed serum testosterone are considered to have 
castration-resistant prostate cancer (CRPC).  Approved therapeutic options for the management 
of patients with CRPC include cytotoxic therapies (mitoxantrone, docetaxel and cabazitaxel), 
immunotherapy (sipuleucel T), an alpha particle emitting radioactive therapeutic agent (radium 
RA 223 dichloride), and second generation hormonal therapies (abiraterone and enzalutamide).  
The goal of treatment with these agents is to prolong survival, improve quality of life, and/or 
slow progression of the disease (Bennett et al. 2014).
1.2
Treatment for Prostate Cancer
Enzalutamide (Xtandi®, Astellas Pharma US, Inc.) is a second-generation androgen antagonist 
that targets multiple steps in the androgen signaling pathway with no reported agonistic effects 
(Sementas et al. 2013, El-Amm et al. 2013).  The drug was originally approved by the Food and 
Drug Administration (FDA) in August 2012 for the treatment of patients with mCRPC who have 
previously received docetaxel (Ning et al. 2013).  This approval was based on the results of a 
double-blind, placebo-controlled, randomized phase III trial that compared enzalutamide 160 mg 
orally daily with placebo (Scher et al. 2012).  The study was stopped prematurely at the time of 
an interim analysis based on the significant improvement in OS that was observed with 
enzalutamide compared to placebo (18.4 vs. 13.6 months; hazard ratio (HR) 0.63; p <0.001).  
The secondary endpoints of prostate-specific antigen (PSA) response rate (RR) (54% vs. 2%) 
and soft-tissue RR (29% vs. 4%) also favored the enzalutamide arm.  
In September 2014, the FDA subsequently approved enzalutamide for patients with mCRPC 
regardless of prior docetaxel exposure based on data from the PREVAIL trial.  These data 
demonstrated the efficacy of enzalutamide in prolonging OS in men with chemotherapy-naïve 
mCRPC who have failed to respond following ADT and have few or no symptoms (Beer et al. 
2014). Men receiving enzalutamide experienced a statistically significant OS benefit compared 
to those receiving placebo (HR 0.71; 95% confidence interval (CI): 0.60-0.84, p<0. 001).

Radiographic progression-free survival (PFS) was also prolonged and there was a 17 month 
delay in the time to initiation of chemotherapy in men receiving enzalutamide.  The RR in men 
with soft tissue metastatic disease was 59% in men receiving enzalutamide compared to 5% of 
patients receiving placebo; the median time to PSA progression was prolonged from 2.8 to 11.2 
months with treatment.  In addition, the percentage of men with PSA decline from baseline of 
>90% was 47% in the abiraterone-naïve population.  Data has shown that a larger decline in PSA 
is associated with improvements in survival (Kelley et al. 1993).
There have not been large randomized trials to evaluate the efficacy of newer generation 
androgen antagonists after previous exposure to another newer generation androgen antagonist.  
Multiple smaller trials have evaluated the activity of enzalutamide in patients that have 
previously received abiraterone and vice versa.  These data suggest the response rates and time to 
progression are vastly diminished when receiving enzalutamide after abiraterone exposure 
(Noonan et al. 2013, Loriot et al. 2013, Smith et al. 2014, Schrader et al. 2014, Badrising et al. 
2014, Cheng et al. 2014).  This is not surprising seeing as both agents target the androgen 
receptor.  Specifically, Schrader, et al, studied enzalutamide in 35 patients with castrate-resistant 
prostate cancer previously treated with docetaxel and abiraterone and found a median time to 
progression on enzalutamide of 4.0 months which will serve as the benchmark for this trial 
(Schrader et al. 2014).
1.3
LY3023414
The phosphatidylinositol-3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of 
rapamycin (mTOR) pathway is one of the most frequently dysregulated pathways in cancer, and 
loss of phosphatase and tensin homolog (gene) (PTEN) leading to constitutive activation of the 
PI3K pathway, is common in advanced prostate cancer (Tang et al. 2014, Edlind et al. 2014, 
Hong et al. 2014, Bitting et al. 2013).  Furthermore, preclinical studies demonstrate an 
association between the PI3K-AKT-mTOR and androgen receptor signaling axes that is 
potentiated as prostate cancer cells develop resistance to ADT and vice versa (Bitting et al. 2013, 
Carver et al. 2011).  Similar crosstalk has been demonstrated between the estrogen receptor 
signaling pathway and the PI3K/AKT/mTOR pathway in breast cancer.  Everolimus, an oral 
mTOR inhibitor, was recently approved in combination with exemestane for the treatment of 
women with advanced hormone receptor-positive, human epidermal growth factor receptor 2 
(HER2)-negative breast cancer after failure of treatment with letrozole or anastozole after 
demonstrating prolonged PFS in this setting (Baselga J. et al. 2012).
LY3023414 is an orally available, small molecule dual kinase inhibitor of class I PI3K isoforms 
and mTOR with good solubility across a wide pH range. In vitro kinase studies have shown that 
LY3023414 binds to the adenosine triphosphate (ATP) active site of PI3K to competitively 
inhibit phosphorylation of phosphatidylinositol-4, 5-bisphosphate (PIP2) at low nanomolar 
concentrations. In nonclinical studies, LY3023414 has demonstrated potent in vivo target 
inhibition that was linked to potent antitumor efficacy.  The nonclinical toxicology profile of 
LY3023414 has enabled a safe clinical starting dose, and a benefit-risk profile acceptable for 
cancer treatment with the toxicities observed in animal species that are manageable, monitorable, 
and likely reversible.  Clinical experience with LY3023414 is discussed in Section 1.3.3.

Nonclinical Toxicology
LY3023414 was evaluated in nonclinical toxicology studies up to 1 month in duration using 
daily oral dosing in rats and dogs to characterize the toxicity.  Based on results from nonclinical 
studies in the rat and the dog, toxicities patients may experience include (but are not limited to) 
gastrointestinal toxicity, bone marrow and lymphoid organ toxicity (decreases in lymphocytes), 
and sores/scabbing of the skin.  Pharmacologic effects of PI3K/mTOR inhibition related to 
glucose metabolism have also been observed, including hyperinsulinemia, hyperglycemia, and 
QT interval prolongation in nonclinical studies.  In a rat embryo -fetal developmental pilot study 
of LY3023414, embryo-fetal lethality was seen along with an increase in fetal and litter 
incidence of external, visceral, and skeletal malformations.
For additional details on nonclinical toxicology data, see Section 5.2.1 of the Investigator’s 
Brochure (IB).
1.3.1.2
Nonclinical Efficacy Pharmacology Summary
LY3023414 is a potent selective inhibitor of the class I PI3K isoforms mTOR and DNA-PK, 
with selectivity in kinase enzyme assays as an ATP competitive inhibitor of PI3K (inhibition 
binding constant [Ki] of 8.5nM). LY3023414 demonstrated inhibitory activity against 
PI3K/mTOR pathway targets in vitro and in vivo as measured by phosphoprotein levels from 
cultured cells and tumor xenografts. LY3023414 showed antiproliferative and cell-cycle 
arresting effects in cultured cancer cells, and anti-angiogenesis activity via inhibition of in vitro 
vascular cord formation.  LY3023414 has excellent solubility and oral bioavailability across a 
wide pH range, allowing for simple suspension formulations to be used for or al administration in 
nude mice.  In xenograft tumor models, LY3023414 demonstrated dose-and time-dependent 
target inhibition, as well as antitumor efficacy in a wide range of tumor models (including renal 
cancer and non-small cell lung carcinoma [NSCLC]). The mouse pharmacokinetic 
(PK)/pharmacodynamics (PDx) model indicates a direct inhibition of downstream target 
phosphoproteins (such as, phospho Akt [pAkt], phospho 70S6K [p70S6K]). LY3023414 has 
potential for combination with standard of care agents to produce synergistic effects in cell 
culture and in vivo xenograft models.
Nonclinical Pharmacokinetics/Pharmacodynamics
1.3.2
Bioavailability of LY3023414 was 66% in dogs, and the clearance was less than hepatic blood 
flow.  No accumulation of LY3023414 was noted following repeated dosing to rats and dogs.  
Also, no consistent gender differences in toxicokinetic parameters were observed in rats or dogs 
throughout the 1-month study.  In vivo metabolism data showed that LY3023414 is metabolized 
predominantly via oxidation in rats and via oxidation and glucuronidation in dogs.  In both 
species, LY3023414 was the largest circulating entity in plasma.  Overall, clearance of 
LY3023414 in rats was primarily via metabolism while clearance in dogs involved metabolism 
as well as elimination via feces and urine.  Fecal excretion was the major route of elimination for 
LY3023414-related radioactivity in both species.

there will be a lead-in (Part A) of approximately 6-12 patients to assess safety, tolerability, and 
potential PK interaction.  Prior to starting this combination therapy on Cycle 1 Day 1, patients in 
Part A will be given single agent LY3023414 every 12 hours (BID) during the initial week 
(called Week -1) to assess LY3023414 PKs at a steady state (Section 5.6) on Day -1 (last day of 
that Week -1).  Once Part A is completed and the combination regimen is shown to be tolerated, 
all subsequent patients will be randomized to receive enzalutamide in combination with 
LY3023414 or in combination with a matching placebo (Part B).  
In numerous clinical trials evaluating AR antagonists, some patients never have a PSA decline 
on abiraterone (after enzalutamide) or enzalutamide (after abiraterone), suggesting primary 
resistance to AR-targeted agents (Noonan et al. 2013, Loriot et al. 2013, Smith et al. 2014, 
Schrader et al. 2014, Badrising et al. 2014, Cheng et al. 2014).  The mechanisms of resistance are 
multifactorial and a better understanding is needed.  A recent report of constitutive AR splice 
variants (AR-Vs) may represent a potential resistance mechanism and AR-V7 may be the most 
important one.  Recently, a prospective biomarker study showed that presence of AR-V7 in 
circulating tumor cells (CTC) of CRPC men on abiraterone or enzalutamide resulted in 
decreased progression-free survival (PSA, clinical, and radiographic) as compared to men whose 
CTCs were AR-V7 negative.  Furthermore, some AR-V7 negative patients became positive 
during treatment, suggesting acquired resistance (Antonarakis et al. 2014).  To explore potential 
mechanism of resistance to AR therapy, this study may evaluate the impact of variants of the 
androgen receptor and other biomarkers (including, but not limited to, PIK3CA, PTEN, RAS, or
AR-V7) in blood and tissue.

patients’ medical records and as a comment on the CRF.
4.
STUDY REGISTRATION
The patient must willingly consent after being informed of the procedures to be followed, the 
experimental nature of the treatment, potential benefits, alternatives, side-effects, risks, and 
discomforts.  Institutional Review Board (IRB) approval of this protocol and consent form is 
required.  Eligible patients who wish to participate in the study will be enrolled into the study.
Registration must occur prior to the initiation of protocol therapy.  Patient registration will be 
performed by Sarah Cannon Development Innovations and will be outlined in the Study 
Reference Manual.  
In Part B, patients who agree to participate in the study and meet eligibility criteria will be 
randomly assigned treatment (1:1) to LY3023414 plus enzalutamide or placebo plus 
enzalutamide stratified by visceral disease status (present or absent) and prior chemotherapy in 
the hormone-sensitive setting when commencing ADT (yes or no).  Randomization will be 
performed using an IWRS (see Study Manual).
5.
STUDY DESIGN
This is a double-blinded, placebo-controlled, randomized Phase II study of the combination of 
enzalutamide plus LY3023414 versus enzalutamide plus placebo in patients with mCRPC who 
have shown disease progression on abiraterone.  
Lead-In (Part A)
Since a formal Phase Ib study has not been conducted with the combination regimen of 
LY3023414 and enzalutamide, there will be a lead-in (Part A) of approximately 6-12 patients to 
assess safety, tolerability, and available PK data for potential PK interaction.
Prior to starting this combination therapy on Cycle 1 Day 1, patients in Part A will be given 
single agent LY3023414 every 12 hours (BID) during the initial week (called Week -1) to assess 
LY3023414 PKs at a steady state (Section 5.6) on Day -1 (last day of that Week -1).  Thereafter, 
patients will receive 200 mg of LY3023414 BID in combination with 160 mg of enzalutamide 
QD beginning Cycle 1 Day 1.  A treatment cycle will be defined as 28 days.  LY3023414 PK

will be again evaluated during the combination therapy dosing (in Cycle 1) to explore any 
potential intra-patient PK interactions with enzalutamide.  If no safety signals are reported and 
the PK profile is acceptable then this combination regimen (LY3023414 200 mg BID + 
enzalutamide 160 mg QD) will be the regimen to be studied in the randomized part of the study 
(Part B) which will commence without the single agent dosing Week -1.
After at least 6 patients have been treated for a full cycle in Part A, a Safety Internal Monitoring 
Committee (SIMC) will conduct a review of the safety and available PK data prior to the 
initiation of the randomized part (Part B) of the study.  If 2 (or more) of 3 or 2 (or more) of 6 
patients in Part A experience DLTs as defined in Section 5, 3 to 6 additional patients will be 
treated at the next lower dose of LY3203414 defined in Table 3 (150 mg PO BID) and assessed 
for DLTs prior to initiation of the randomized Part B portion of the study.  If there is a PK 
interaction deemed to be clinically significant by the SIMC, the SIMC may recommend 
enrollment of approximately 6 additional patients to further evaluate the safety of the 
combination, or explore other doses of LY3023414 in combination with enzalutamide.  In the 
case of unacceptable and/or unmanageable toxicity of the combination the SIMC may decide to 
discontinue the study upon completion of Part A or proceed with a lower LY3023414 dose level 
tolerated in combination with enzalutamide.  All outcomes from these safety reviews will be 
communicated in a timely manner to the participating investigators so that they may notify their 
IRBs.  No amendment will be needed to proceed with an adjusted dose level of LY3023414.
The SIMC will, at a minimum, be composed of a Sponsor-Assigned Clinical Research Physician, 
Study Chair, Medical Monitor, Safety Scientist, and Biostatistician.

A toxicity will be considered dose-limiting if it occurs within the first cycle of treatment (28 
days) to Part A patients and is deemed at least possibly related to study drug.  Dose-limiting 
toxicities will be defined as any one of the following AEs:

Grade 4 thrombocytopenia; Grade 4 neutropenia ≥7 days; Grade ≥3 febrile neutropenia; 
and Grade ≥3 thrombocytopenia with Grade ≥2 hemorrhage;

Grade ≥ 3 non-hematologic toxicity despite maximal medical management with the 
exception of:  

Diarrhea, nausea, or vomiting that resolves to ≤ Grade 2 within 48 hours  

ALT/AST elevation that resolves to ≤ Grade 2 within 7 days 

Grade 3 mucositis that resolves to ≤ Grade 2 within 7 days.  Grade 4 
mucositis of any duration will be considered a DLT.

Grade 3 fasting hyperglycemia that resolves to ≤ Grade 2 within 7 days.  
Grade 4 hyperglycemia of any duration that results in intensive care unit
admission will be considered a DLT.

Grade 3 fatigue that resolves to ≤ Grade 2 within 5 days. 

Grade 3 hypertension controlled with medical therapy.  

Any lab abnormalities that are not clinically significant and resolve in 72 
hours.


Treatment delay of ≥14 days due to unresolved AE

Any other study drug related AE that is clinically significant, does not respond to 
supportive care, or is judged to be an unacceptable and/or unmanageable study drug 
related AE by the investigator in collaboration with the Medical Monitor.
Determination of Dose-Limiting Toxicities
The patient population used for determination of DLTs will consist of patients who have met the 
minimum safety evaluation requirements of the study, and/or who have experienced a DLT.  
Minimum safety requirements will be met if, during Cycle 1 of treatment, the patient receives at 
least 75% of study drug regimen (LY3023414 and enzalutamide) and is observed for at least 28 
days following the first dose of study drugs.
Double-blinded, Placebo-Controlled Randomized Study (Part B)
Once Part A has been evaluated by the SIMC and the dose and schedule of LY3023414 in 
combination with enzalutamide is selected to move forward, the double-blinded, placebo-
controlled randomized portion (Part B) will be initiated.  
Approximately 132 patients will be enrolled in Part B and they will be randomized (1:1) to one 
of two treatment groups:

5.1
Treatment Plan
Patients will self-administer LY3023414 or matching placebo and enzalutamide daily by oral 
administration.  The order in which these drugs and/or placebo are taken is not relevant to this 
study.
On the PK days (see Section 5.6), patients will be asked hold study drugs administration until the 
pre-dose PK sample at the investigating site has been collected.
LY3023414 or Placebo
5.1.1
LY3023414 or matching placebo will be self-administered by the patient BID on continuous 
daily dosing.
Patients should take the morning and evening doses of LY3023414 approximately 12 hours apart 
(preferably within a 10- to 14-hour range).  LY3023414 or matching placebo should be taken 
with a glass of water at approximately the same time each day.  LY3023414 or matching placebo 
can be taken with or without food.  Patients should swallow the capsules as a whole and should 
not chew or crush them.  
If the patient misses a dose of LY3023414 or matching placebo, the patient should take the dose 
as soon as possible, but not less than 6 hours before the next dose is due for twice daily dosing.  
If the next dose is due in less than 6 hours, the patient should skip the missed dose and take the 
next dose as scheduled.
If vomiting occurs after taking LY3023414 or matching placebo, the patient should be instructed 
not to retake the dose.  Patients should take the next scheduled dose of LY3023414 or matching 
placebo.  If vomiting persists the patient should contact the investigator.
LY3023414 or matching placebo compliance will be assessed by pill counts on Day 1 of each 
cycle.  The research staff will count and document the amount of LY3023414 or matching 
placebo taken and returned by the patient.
Enzalutamide
5.1.2
All patients will receive a standard regimen of enzalutamide 160 mg (four 40 mg capsules) QD 
for continuous daily dosing.
Enzalutamide will be self-administered by the patient.  Enzalutamide will be taken together with 
one of the two daily doses of LY3023414 or matching placebo.  Enzalutamide can be taken with 
or without food.  Enzalutamide capsules should be swallowed whole.  Patients should not chew, 
dissolve, or crush them.  
If a dose of enzalutamide is missed, the patient should take it as soon as they remember.  If the 
patient forgets to take his dose before 6:00 pm, then the dose should be withheld that day and the 
enzalutamide should be restarted the following day.  However, patients that expe rience fatigue 
while taking enzalutamide may take it at night after Cycle 1 of treatment.  The Medical Monitor 
should be consulted for PK logistics post Cycle 1 for patients who require dosing at night .  
Enzalutamide achieves steady state by day 28 of treatment.  
At each new cycle, patients will be prescribed sufficient supplies until the next visit.

Enzalutamide drug compliance will be assessed at the beginning of a new cycle.  
5.2
Treatment Duration
The end of the study is defined as the last visit of the last patient on the study.
Patients will be evaluated for toxicity and symptomatic progression at the start of each cycle.  
PSA will be measured at the beginning of each 28 day cycle.  Prior to Cycle 3 and after every 2 
cycles, restaging will occur with imaging and PSA as defined in Appendix D (Schedule of 
Assessments).  
Patients will be allowed to continue on therapy as long as they do not meet the discontinuation 
criteria listed in Section 3.3, and are considered, by the investigator, to still be receiving clinical 
benefit (patients may continue on therapy after progression criteria have been met only if they 
are considered to be receiving clinical benefit after consulting with the study Medical Monitor
and depending upon availability of study drug).
5.3
Treatment Assignment Unblinding Procedures
It is very important for all study personnel to respect the blinded nature of the study; there is no 
intention to routinely unblind individual patients at any time prior to the conclusion of the study.  
In the event of an emergency unblinding thought to be related to LY3023414 (or matching 
placebo) or a medication error, a request for urgent safety unblinding should be made to the 
Medical Monitor.  Emergency unblinding will be allowed only when approved by the Medical 
Monitor.  The investigator may hold administration of LY3023414 or matching placebo while 
waiting for a decision on unblinding to be made.  All unblinding must be documented by the site.
Examples of emergencies requiring unblinding include: 

A life-threatening, unexpected AE that is thought to be related to LY3023414 and for 
which unblinding would change or influence treatment decisions.

Medication error, such as an accidental overdose, that would warrant unblinding in order 
to more effectively manage toxicity.
For additional information regarding unblinding procedures please refer to the Study Reference 
Manual.
5.4
Concomitant Medications
Patients will be instructed not to take any additional medications except those listed in 
Section 5.4.1 below during the course of the study without prior approval of the investigator and 
Sponsor.  At each visit, the patient will be asked about any new medications he is taking or has 
taken after the start of the study drug.
Permitted Concomitant Medications
5.4.1
Premedication with anti-emetics is allowed according to standard practice guidelines.
Medications may be administered for maintenance of existing conditions prior to study 
enrollment or for a new condition that develops while on study, including but not limited to the 
following:


Bisphosphonate use, as recommended according to practice guidelines

Receptor activator of nuclear factor kappa-B ligand (RANKL) inhibitor use, as 
recommended according to practice guidelines

Anticoagulation with coumadin -derivatives will not be permitted.  However, a maximum 
daily dose of 1 mg will be permitted for port line patency.  Should a thrombotic event 
occur while the patient is receiving treatment the patient may continue, but low molecular 
weight heparin (LMWH) will be the preferred treatment.

Patients who develop hyperglycemia during the study should be treated according to the 
American Diabetes Association guidelines.  It is recommended to start treatment wit h 
metformin.
Other medications considered necessary for the patient’s safety and well-being may be given at 
the discretion of the investigator with the exception of those listed in Section 5.4.2.
Prohibited Concomitant Medications
5.4.2
The following treatments are prohibited while in this study:

No other investigational therapy should be given to patients.  No anticancer agents other 
than the study medications should be given to patients.  If such agents are required for a 
patient, then the patient must first be withdrawn from the study.
Concomitant Medications to be avoided
5.4.3
The following treatments should be avoided while in this study:
Enzalutamide is a strong CYP3A4 inducer and a moderate CYP2C9 and CYP2C19 inducer (see 
Appendix I).  
o
Avoid strong of CYP2C8 inhibitors, as they can increase the plasma exposure to 
enzalutamide (Appendix I). If co-administration is necessary, consider reducing 
the dose of enzalutamide.
o
Avoid strong or moderate CYP3A4 or CYP2C8 inducers as they can alter the 
plasma exposure of enzalutamide (Appendix I).
o
Avoid CYP3A4, CYP2C9 and CYP2C19 substrates with a narrow therapeutic 
index, as enzalutamide may decrease the plasma exposures of these drugs. If 
enzalutamide is co-administered with warfarin (CYP2C9 substrate), conduct 
additional INR monitoring.
LY3023414 is a weak inhibitor of CYP3A4 and from in vitro data the major cytochrome P450 
involved in the clearance of LY3023414 was identified as CYP3A (~80%):
o
Avoid strong inhibitors of CYP3A4 and strong and moderate inducers of 
CYP3A4 (other than enzalutamide)
o
Drugs causing QTc interval prolongations should be avoided (Appendix H)
Approximately 20% of LY3023414 is metabolized by CYP1A2.  Therefore,

o
Particular attention should be paid in recording CYP1A2 inducers/inhibitor in the 
concomitant medication (Appendix I).
o
Smoking should be avoided and for all patients smoking habit should be recorded.
Patients receiving these agents should be treated with other equivalent medications if possible:
o
Patients should avoid grapefruit, Seville oranges, or Star fruit.
o
Herbal preparations/medications should be avoided throughout the study.  These 
herbal medications include, but are not limited to: St. John’s wort, kava, ephedra 
(ma huang), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw 
palmetto, and ginseng.  Patients should stop using these herbal medications 7 days 
prior to first dose of study drug.
5.5
Correlative Studies
Biological samples (i.e., blood and fresh or archival tissue samples, primary or metastatic 
lesions) will be requested and may be analyzed to identify potential biomarkers predictive of 
clinical efficacy of the study drugs and disease progression in this patient population.  The time 
points for the collection of samples for correlative testing are specified in Appendix D.
Tumor biopsy specimens from the primary site or from metastatic lesions from all patients with 
available archived tissue will be collected.  Tumor and blood specimens may be tested for 
biomarkers including, but not limited to, mutation and expression of PIK3CA, PTEN, or RAS and 
others.  Samples may be assessed by targeted exome sequencing or other techniques as 
scientifically appropriate.  The status of these biomarkers will be analyzed in an attempt to 
correlate to the clinical patient outcome (e.g. RR and PFS).  Blood samples drawn from the 
patients at baseline, Day 1 of Cycle 1, and every 2 cycles thereafter, and at end of treatment visit
may be assessed to explore potential gene signature(s) for clinical benefit to study treatment, 
such as PIK3CA, PTEN, or RAS and AR-V7.
Information regarding shipment, handling, and length of retention time, etc. of tissue and blood 
will be provided in the Laboratory Manual.
Samples for Pharmacogenetics and/or Tailoring Biomarkers
5.5.1
Collection of samples for biomarker research is also part of this study.  Blood and Tissue 
samples will be collected.
Samples for biomarker research to be collected from all patients in this study are the follow ing:
•
blood
•
tumor tissue (if available; archival or fresh, primary or metastatic lesions)
Samples may be tested to identify biomarkers predictive of clinical efficacy and disease 
progression in this patient population.
Samples will be stored and analysis may be performed on biomarker variants thought to play a 
role in PI3K pathways, including, but not limited to, PIK3CA, PTEN, or RAS and AR-V7, to 
evaluate their association with observed clinical outcomes to study treatment.

AMENDMENT 3: 25 January 2017
v 4.0
Page 43 of 95
Based on the limited intra-patient variability in LY3023414 exposure (~25%) in study CBBA, 
the sample size of 6 to 12 patients is adequate to investigate the impact of enzalutamide on 
LY3023414 exposure.  Enzalutamide is anticipated to decrease LY3023414 exposure.  A 
decrease of 30 % of LY3023414 exposure in the presence of enzalutamide should be detected 
with a sample of 6 to 12 patients.  The 90% confidence interval around a mean value of 1.5 for 
the ratio LY3023414 AUC alone: LY3023414 AUC in the presence of enzalutamide should be 
1.2 to 1.8 for a sample size of 10 patients.
Furthermore, the plan includes investigation of enzalutamide PK to determine enzalutamide 
AUC at steady state (on day 15) when administered in combination with LY3023414 in all Part 
A patients (i.e. in at least 6 and up to 12 patients). Enzalutamide exposure will be compared to 
historical data following enzalutamide single agent therapy.  Additionally, the PK parameters of 
the active N-desmethyl enzalutamide metabolite may be determined. 
LY3023414 concentration will be characterized in whole blood (per the schedule presented in
Table 1). Venous blood will be drawn at each time point using a micro sampling technique 
(dried blood spot [DBS] sampling) for quantifying LY3023414 concentration. A hematocrit 
value (which can be obtained from a complete blood count [CBC]) is required within +/- 2 days 
of sampling for PK.  In Part A, classical plasma samples will also be drawn to compare
LY3023414 concentrations.  Detailed instructions and supplies for the collection, handling, and
shipping of blood and plasma samples will be provided by either the sponsor or Sarah Cannon 
Development Innovations.  LY3023414 will be assayed using a validated DBS or plasma liquid 
chromatography (LC)-mass spectrometry (MS)/MS method.
Pharmacokinetic studies will be done during Part A to determine plasma levels of enzalutamide 
following concurrent administration of enzalutamide with LY3023414.  Additionally, 
concentrations of the active N-desmethyl enzalutamide metabolite may be quantified.  The 
schedule for collection of whole blood specimens is presented in Table 1.  Detailed instructions 
and supplies for the collection, handling, and shipping of plasma samples will be provided by 
either the Sponsor or Sarah Cannon Development Innovations.  Enzalutamide will be assayed 
using a validated LC-MS/MS method.

retained for a maximum of 1 year following last patient visit for the study.
5.7
Pharmacogenomic (PGx) Assessement
There is growing evidence that genetic variation may impact a patient’s response to therapy. 
Variable response to therapy may be due to genetic determinants that impact drug absorption, 
distribution, metabolism, and excretion, the mechanism of action of the drug, the disease 
etiology, and/or the molecular subtype of the disease being treated.
In the event of an unexpected AE, the samples may be genotyped and analysis may be performed 
to evaluate a genetic association with response to LY3023414. These investigations may be 
limited to targeted exome sequencing approach of known targets involved in drug metabolism or, 
if appropriate, genome-wide association studies may be performed to identify regions of the 
genome associated with the variability observed in drug response.
The PGx sample is part of the biomarker sample.  Therefore, there is no separate kit for PGx 
samples.  Samples will only be used for investigations related to disease and drug or class of 
drugs under study in the context of this clinical program. They will not be used for broad

exploratory unspecified disease or population genetic analysis. Samples will be identified by the 
patient number (coded) and stored for up to 15 years after the last patient visit for the study at a 
facility selected by the sponsor. The sample and any data generated from it can only be linked 
back to the patient by investigator site personnel.
6.
DOSE MODIFICATIONS
If an AE occurs, the AE will be graded utilizing the NCI CTCAE v 4.03 
(http://evs.nci.nih.gov/ftp1/CTCAE/CTCAE_4.03_2010-06-14_QuickReference_8.5x11.pdf), 
and appropriate supportive care treatment will be administered as needed to decrease the signs 
and symptoms thereof.  Dose adjustments will be based on the organ system exhibiting the 
greatest degree of toxicity.
Doses of LY3023414 will be modified based on hematologic and non-hematologic toxicity.  If 
dose reductions are necessary, they will be permanent for the remainder of the treatment.  No
dose reductions due to study drug related toxicities of LY3023414 or enzalutamide are permitted 
in Part A during Cycle 1.  
During Part B and after Cycle 1 in Part A, dose reductions for enzalutamide and LY3023414 
may be adjusted according to Table 3.  If the responsible study drug can be identified, it may be 
adjusted according to the dose modification table and the patient may continue with the other 
study drug, as appropriate.  If the patient is receiving the lowest allowable dose and experiences 
an AE requiring a dose reduction, the offending study drug should be discontinued.  If the 
offending study drug is discontinued, the patient may continue single-agent treatment.  
If any AE occurs, it should resolve to a level that, in the opinion of the investigator, is reasonable 
to allow for continuation of treatment taking into consideration the recommendations below.
If a patient experiences a Grade 3 drug-related AE or an intolerable Grade 2 AE: 
•
LY3023414 dosing should be withheld until symptoms improve to ≤ Grade 1 or baseline 
then may be resumed at a reduced dose according to Table 3.  In part B only, re-
escalation of LY3023414 may be considered if clinically warranted, following discussion 
and approval by the medical monitor.  
•
Enzalutamide dosing must be withheld for one week or until symptoms improve to 
< Grade 2 then may be resumed per the package insert at the same or reduced dose 
according to Table 3.  
Permanently discontinue study drugs for Grade 4 adverse events.  Re-challenge of patients with 
dose-reduced study drug(s) following recovery from Grade 4 AEs may be considered on a case-
by-case basis in consultation with the medical monitor.  
Grade 3 or 4 laboratory changes that are not clinically significant and which can be corrected 
within 48 hours may not require dose modification.
If the AE is clearly attributable to one drug, then dose reduction of only that drug is necessary.
For toxicities possibly caused by both drugs, the dose levels of both should be reduced.

Any patient requiring an AE-related dose delay of more than 21 days from the intended day of 
the next scheduled dose due to a study drug related AE must be discontinued from the study, 
unless discussed with the Medical Monitor.
Dose delays within a cycle do not alter the start of the next scheduled cycle.  Assessments for 
any missed visit will be done when the patient returns to the clinic.  These would need to be 
entered into the EDC as unscheduled.
A maximum of two dose reductions per drug are allowed in this study.  If more than two dose 
reductions of study drug(s) are necessary for a patient, the responsible agent will be 
discontinued.

Analysis Population
The following analysis populations will be used:

All patients who have signed the informed consent form (i.e. screening failures plus 
patients enrolled) will comprise the All Patients Set ( APS).  The All Patients Set will be 
used to describe the patient disposition.

All enrolled patients randomized to treatment arms will comprise the Full Analysis Set 
(FAS).  Information using this population will be tabulated by treatment arm, as 
randomized (Intent to Treat) according to the IWRS, unless otherwise indicated. This 
population will be used for the primary analyses of the efficacy endpoints.

All randomized patients having no major protocol deviations will comprise the Per 
Protocol Analysis Set (PPAS).  Those protocol deviations that are deemed to have an 
important impact on the analysis of study endpoints and leading to the exclusion of a 
patient will be listed in the Statistical Analysis Plan (SAP) prior to database lock.  This 
analysis set will be used for sensitivity analyses of efficacy endpoints.

All patients who have received at least one dose of study treatment will comprise the 
Safety Analysis Set (SAF).  Patients will be allocated as treated. 
10.4
Data Analysis
Descriptive statistics, including mean, median, standard deviations, minimum and maximum for 
all continuous measures will be tabulated and reported.  Percentages and frequencies for all 
categorical measures will also be presented.  A SAP outlining methods for analysis and data 
display will be developed and approved prior to unblinding.  Any deviation(s) from the approved 
plan or ad-hoc evaluations or analyses will be properly documented in the clinical study report.
Demographics and Baseline Characteristics
10.4.1
Demographic and baseline disease characteristics will be summarized by treatment group.  Data 
to be tabulated will include demographic features such as age, sex and race, as well as 
stratification factors and disease-specific characteristics.
The number and percentages of patients screened, randomized, treated, completed the 
treatment/study and withdrawn from treatment/study for any reasons will be presented overall 
and also by treatment group.
Efficacy Analysis
10.4.2
All efficacy analyses will be performed using the FAS.  Sensitivity analyses may be performed 
using the PPAS.
Measurement of PSA levels, bone scans and CT scans will be performed for all patients at 
screening, after every 2 cycles (PSA will be measured monthly), and at follow-up visits before a 
subsequent anti-cancer therapy or death.  
Tumor reassessment will be done by the same method used to establish baseline tumor 
measurements for each patient.  For a response of stable disease (SD), measurements must meet 
the SD criteria at least 6 weeks after study entry.

10.4.2.1
Primary Endpoint
Progression–free survival (PFS)
PFS will be the primary endpoint for this study.  PFS is defined as the time from randomization 
until the date of disease progression per PCWG2 or death by any cause regardless of whether the 
patient withdraws from study drug or receives a subsequent anti-cancer therapy (as determined 
by the investigator).  Patients who have not progressed or died at the time of assessment will be 
censored at the time of the last date of assessment (tumor evaluation or PSA level).  Patients who 
are randomized but do not receive treatment and patients who have no evaluable visits will be 
censored on day 0 unless they die within two visits of baseline.  In the event patients demonstrate 
progression based on RECIST v 1.1, PSA levels, and/or bone scans at differing points, the 
earliest date of documented progression will be used to calculate PFS.
PFS will be derived based on relevant scan or lab dates, and not associated visit dates.  In the 
event that RECIST v 1.1 assessments are conducted across multiple days, the date of progression 
will be based on the earliest of the dates of the component that triggered the progression.  When 
censoring, the patient will be censored at the latest of the dates contributing to the particular visit 
assessment.
Treatment group differences will be tested using an unstratified log rank test. The stratified 
analysis using the stratification factors defined as part of the randomization process will be 
performed as sensitivity analysis.
The Kaplan-Meier (Kaplan E and Meier P 1958) product limit method will be used to estimate 
the median PFS and the associated 95% CI for the two treatment arms. Progression-free survival 
will additionally be analyzed using a Cox Proportional Hazards Model, and will be used to 
estimate the HR of PFS in the enzalutamide plus LY3023414 arm relative to the enzalutamide 
plus placebo arm and the associated 95% CI.
10.4.2.2
Secondary Endpoints
Overall Response Rate (ORR)
The ORR based on each patient’s best objective response will be determined for all patients 
evaluable via the RECIST v 1.1 criteria.  The ORR (%) will be calculated as the number of 
patients with best objective response of CR or PR divided by the number of patients with 
measurable disease at baseline.  The best objective response for a given patient will be based on 
objective responses determined from data obtained up to: progression, the last evaluable 
assessment in the absence of progression, or initiation of subsequent anticancer therapy.  Patients 
for whom an objective response cannot be determined or for who the best objective response is 
‘not evaluable’ (NE) will be considered non-responders.  The ORR will be summarized along 
with the 95% Clopper Pearson CI for each treatment arm. 
Treatment group comparisons in ORR will be evaluated using Chi-square test and Cochran-
Mantel Haenszel test adjusted by stratification factors.
Percent change from baseline in PSA levels
The percent change from baseline in PSA levels after 12 weeks on study and the maximum 
percent change from baseline will be summarized using box-whisker plots for each treatment

arm.  For patients who discontinue on or before the 12 week assessment or for whom the 12 
week assessment is missing, the last observation prior to the week12 assessment will be utilized.  
Patients with no post-baseline PSA data will be excluded from the summaries.
Time to Disease Progression (TTP)
TTP will be calculated as the time from randomization to objective disease progression.  The 
date of progression will be determined as described above for PFS.  Patients who die for any 
reason prior to disease progression will be censored at the time of death.  Treatment group 
differences will be tested using a stratified log rank test as for PFS.  
TTP will be analyzed in the same manner as those in PFS.
Study Drug Interactions
As specified in Sections 5.6 and 10.4.4, collection of PK samples is planned to be able to 
compare, within patient, the steady state LY3023414 AUC, Cmax, and Ctrough (Cmin) following 
LY3023414 administration as a single agent and in combination with enzalutamide.  These data 
will enable to determine whether enzalutamide impacts LY3023414 exposure.
As specified in Sections 5.6 and 10.4.4, collection of PK samples is planned to determine in a 
limited number of patients (Part A, Lead-In), the steady state exposure of enzalutamide.  These 
results will be compared to historical enzalutamide data.  This population to population 
comparison of enzalutamide exposure is believed to be adequate given that it is not anticipate 
that LY3023414 would impact enzalutamide clearance.
10.4.2.3
Exploratory Endpoints
The number and proportion of patients having an alteration in pre-specified markers at baseline, 
including but not limited to PIK3CA, PTEN, RAS, and AR-V7, may be presented if deemed 
relevant.  The relationship between clinical outcomes and the presence of alterations in each 
marker may also be summarized using methods appropriate for each specific clinical outcome as 
specified in the SAP.
10.4.2.4
Subgroup Analyses
For exploratory purposes, efficacy sub-group analyses may also be performed if applicable, 
using the FAS/PPAS.  The details of these analyses and selection of the prognostic factors and/or 
baseline characteristics will be specified in the SAP.
Safety Analysis
10.4.3
The NCI CTCAE v 4.03 will be used to grade all AEs (severity grade).  A copy of the CTCAE 
scoring system may be downloaded from: 
http://evs.nci.nih.gov/ftp1/CTCAE/CTCAE_4.03_2010-06-14_QuickReference_8.5x11.pdf.
Duration and treatment of toxicities will be recorded.  The safety measures will be assessed on 
an ongoing basis.  The safety variables will be assessed by body system.  Any AEs that are 
considered probably or possibly study drug-related will be monitored until resolution or 
stabilization.
Toxicity profile data will include AEs and laboratory parameters.  Safety data will be tabulated 
for all patients who receive any amount of study medication , overall and by part and treatment

group.  Adverse terms recorded on the eCRFs will be standardized using the Medical Dictionary 
for Regulatory Activities (MedDRA).  Treatment -emergent AEs (TEAEs), defined as events that 
start or worsen after the first dose of study treatment, will be summarized and t abulated in 
accordance with system organ class (SOC) and preferred term by overall incidence, severity, and 
relationship to study treatment.  The tabulation of laboratory parameters will indicate the normal 
range of each parameter.  Each value will be classified according to CTCAE v 4.03 where 
applicable.
Other safety endpoints, including laboratory results, vital signs and ECG findings, will be 
summarized for all patients in the Safety Analysis Set, overall and by part and treatment group. 
Concomitant medications will be coded using the World Health Organization-Drug Dictionary 
and they will be listed and summarized by treatment group.
Pharmacokinetics/Pharmacodynamics
10.4.4
Pharmacokinetic analyses will be conducted on patients who have received at least 1 dose of the 
study drug and have had sufficient post-dose samples collected to allow estimation of PK 
parameters.  Blood and plasma (Part A only) concentrations of LY3023414 and plasma 
concentration for enzalutamide will be used to calculate LY3023414 and enzalutamide PK 
parameters, respectively.  The PK parameters will be calculated by standard noncompartmental 
methods.
The primary parameters for analysis will be maximum concentration (Cmax) and area under the 
concentration-time curve (AUC) of LY3023414 and Enzalutamide following multiple doses.  
Other noncompartmental parameters, such as t1/2, CLss/F, and Vss/F may be reported.  These 
parameters will be listed by individual patient and summarized by descriptive statistics (means, 
medians, ranges, standard deviations and coefficient of variation and, as appropriate.
For Part A the ratio of LY3023414 AUCs when administered concomitantly with enzalutamide 
over single agent will be computed to quantify the possible impact of enzalutamide on 
LY3023414 exposure (LY3023414 AUC ratio = AUC,ss, alone : AUC, ss, presENZ ; with 
the dosing interval for LY3023414 that is 12 h, ss meaning that the PK assessment is done at 
steady state ; alone and presENZ meaning that LY3023414 was administered either alone or with 
enzalutamide).  The result will be summarized by descriptive statistics (mean, median, range, 
standard deviations and coefficient of variation) and the 90% confidence interval for this ratio 
will be computed.
Additional exploratory analyses will be performed if warranted by data and other validated PK 
software programs may be used if appropriate and approved by Global Pharmacokinetic 
management.  It is planned that LY3023414 PK data will be analyzed using the nonlinear mixed 
effect modeling (NLME) techniques.  The version of any software used for the analysis will be 
documented and the program will meet the Lilly requirements of software validation. 
Further details on the PK/PD analysis will be documented in a separate PK/PD analysis plan.
10.5
Handling of Missing Data
Except where noted above, missing data will not be estimated or imputed.

AMENDMENT 3: 25 January 2017
v 4.0
Page 60 of 95
The criteria for assessing safety in these patients are found in Section 5.
Unblinding Patients
10.6.4
There is no intention to routinely unblind individual patients at any time.  Individual requests for 
urgent safety unblinding require the approval of the Medical Monitor.  
There also may be instances where unblinding of a patient(s) may be required for a safety review 
at the request of the Sarah Cannon Development Innovations Medical Monitor or SIMC or for 
Regulatory Authority reporting requirements.
After all patients have completed protocol treatment and the database has been locked, the trial 
will be unblinded for analysis of the safety and efficacy outcomes.
11.
SAFETY REPORTING AND ANALYSES 
Investigators are responsible for monitoring the safety of patients who have entered into this 
study and for alerting Lilly or its designee to any event that seems unusual, even if this event 
may be considered an unanticipated benefit to the patient.  The investigator is responsible for the 
appropriate medical care of the patient during the study.
The investigator remains responsible for following, through an appropriate health care option, all 
AEs that are serious or that caused the patient to discontinue before completing the study.  The 
patient should be followed until the event is resolved, the event is no longer considered to be 
drug-related, the event becomes stable or returns to baseline, a new treatment is initiated for the 
patient, or the patient dies or is lost to follow -up.  Frequency of AE and SAE follow-up 
evaluation is left to the discretion of the investigator.
Investigators or their designees must document their review of each laboratory report.
11.1
Adverse Events
Lilly has standards for reporting AEs that are to be followed regardless of applicable regulatory 
requirements that may be less stringent.  A clinical study AE is any untoward medical occurrence 
in a patient or clinical investigation patient administered a pharmaceutical product and which 
does not necessarily have a causal relationship with this treatment.  An AE can therefore be any 
unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or 
disease temporally associated with the use of medicinal (investigational) product, whether or not 
related to the medicinal (investigational) product.  Any clinically significant findings from labs, 
ECGs, vital sign measurements, and so on, that occur should also be reported to Lilly or its 
designee as an AE using the same guidelines and schedules as those for AEs.  Lack of drug 
effect is not an AE in clinical studies because the purpose of the clinical study is to establish drug 
effect.
The investigator, monitor, and sponsor will review the collected data regularly for evidence of 
AEs.  All patients will be assessed routinely for AEs as outlined in the study schedule.  All AEs 
observed will be graded using CTCAE Version 4.03.

AMENDMENT 3: 25 January 2017
v 4.0
Page 61 of 95
The CTCAE Version 4.03 will serve as the reference document for choosing appropriate 
terminology for, and grading the severity of, all AEs and other symptoms.  For AEs without 
matching terminology within the CTCAE Version 4.03 criteria, the investigator will be 
responsible for selecting the appropriate SOC and assessing severity grade based on the intensity 
of the event.  Note that both CTCAE term (actual or coded) and severity grade must be selected 
by study site personnel and collected on the CRF.  This collection is in addition to verbatim text 
used to describe the AE.  
Minor updates to the CTCAE Version 4.03 from the National Cancer Institute (NCI) will not 
necessitate a protocol amendment and the use of updated CTCAE Version 4.0 will not be 
considered a protocol violation.  
In addition to collecting the AE verbatim, the CTCAE term, and the CTCAE severity grade, AE 
verbatim text will also be mapped by the sponsor or designee to corresponding terminology 
within MedDRA.
Cases of pregnancy that occur during paternal exposures to study drug should be reported.  Data 
on fetal outcome and breastfeeding should be collected, if feasible, for regulatory reporting and 
drug safety evaluation.  
For all enrolled patients, study site personnel will record the occurrence and nature of each 
patient’s preexisting conditions, including clinically significant signs and symptoms of the 
disease under treatment in the study.  While the patient is on study, site personnel will record any 
change in these preexisting condition(s) and the occurrence and nature of any AEs.  All AEs 
related to protocol procedures are reported to Lilly or designee.
If a patient's dosage is reduced or treatment is discontinued as a result of an AE, study site 
personnel must clearly report to Lilly or its designee the circumstances and data leading to any 
such dosage reduction or discontinuation of treatment.  This information must also be 
documented in the eCRF.
The investigator decides whether he or she interprets the observed safety signals as either related 
to disease, to the study medication, study procedure, or other concomitant treatment or 
pathologies.  
To assess the relationship of the AE to the study drug, the following terminologies are defined:

Probably related:  a direct cause and effect relationship between the study treatment and 
the AE is likely.

Possibly related:  a cause and effect relationship between the study treatment and the AE 
has not been demonstrated at this time and is not probable, but is also not impossible.

Does not know:  the investigator cannot determine.

Not related:  without question, the AE is definitely not associated with the study 
treatment.
As per Lilly’s standard operating procedures, all “probably related,” “possibly related,” or “does 
not know” AEs and SAEs will be defined as related to study drug.

11.2
Serious Adverse Events
Previously planned (that is, prior to signing the informed consent form [ICF]) surgeries should 
not be reported as SAEs unless the underlying medical condition has worsened during the course 
of the study.
Preplanned hospitalizations or procedures for preexisting conditions that are already recorded in 
the patient’s medical history at the time of study enrollment should not be considered SAEs.  
Hospitalization or prolongation of hospitalization without a precipitating clinical AE (for 
example, for the administration of study therapy or other protocol-required procedure) should not 
be considered SAEs.
An SAE is any AE during this study that results in 1 of the following outcomes:

death

initial or prolonged inpatient hospitalization (except for study drug administration)

a life-threatening experience (that is, immediate risk of dying)

persistent or significant disability/incapacity

congenital anomaly/birth defect

considered significant by the investigator for any other reason.
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered SAEs when, based on appropriate medical judgment, they 
may jeopardize the patient and may require medical or surgical intervention to prevent 1 of the 
outcomes listed in this definition.  
Serious AEs due to disease progression, including death, should not be reported unless the 
investigator deems them to be possibly related to the study drug.
Study site personnel must alert Lilly or its designee of any SAE within 24 hours of investigator 
awareness of the event via a sponsor-approved method.  Alerts issued via telephone are to be 
immediately followed with official notification on study-specific SAE forms.  This 24-hour 
notification requirement refers to the initial SAE information and all follow-up SAE information.
If an investigator becomes aware of SAEs occurring after the patient’s participation in the study 
has ended, and the investigator believes that the SAE is related to a protocol procedure or study 
drug, the investigator should report the SAEs to the sponsor, and the SAEs will be entered in the 
Lilly Safety System.
Information on SAEs expected in the study population independent of drug exposure and that 
will be assessed by the sponsor in aggregate periodically during the course of the study may be 
found in the IB.

Adverse Event and Serious Adverse Event Reporting
11.2.1
Prior to Administration of Study Drug(s)
During screening, all AEs and SAEs (regardless of relatedness to protocol procedures) are 
collected after the patient has signed the informed consent document.  For patients who do not 
enroll in the study (that is, receive at least 1 dose of study drug), only AEs and SAEs related to 
protocol procedures are required to be collected.
On Study
All AEs and SAEs, regardless of relatedness to study drug, or protocol procedures, occurring 
while the patient is receiving study drug(s) must be reported to Lilly or its designee.  A patient is 
considered to be receiving study drug from the time he/she receives the first dose of study 
drug(s) to when he/she receives the last dose of study drug(s).
Follow-Up Visit
All AEs and SAEs, regardless of relatedness to study drug, or protocol procedures, occurring 
during the Follow-Up Visit must be reported to Lilly or its designee.  The Follow-Up Visit starts 
the day after the last dose of study drug.  At the end of the Follow -Up Visit, the patient will be 
required to have specific safety assessments according to the Study Schedule (Appendix D).  The 
timing of these safety assessments is 30 days ± 3 days after the last dose of study drug.
Following the safety assessments, which mark the end of the Follow -Up Visit, the patient will be 
discontinued from the study, unless there is an ongoing AE or SAE that is possibly related t o 
study drug.  In this instance, the patient should be seen for subsequent follow-up visits until the 
event is resolved, the event is no longer considered to be drug-related, the event becomes stable 
or returns to baseline, a new treatment is initiated for the patient, or the patient dies or is lost to 
follow-up.  
After the Follow-Up Visit, only new AEs or SAEs that are considered possibly related to study 
drug or protocol procedures should be reported to Lilly or their designee.
To report an SAE, the Lilly SAE Report Form should be completed with the necessary 
information.
The SAE report should be sent to Lilly via fax using the following contact information (during 
both business and non-business hours):
Lilly Safety Department
Safety Dept. Fax #:      1- 866-644-1697
Transmission of the SAE report should be confirmed by the site personnel submitting the report.
Follow-up information for SAEs and information on non -serious AEs that become serious should 
also be reported to Lilly as soon as it is available; these reports should be submitted using the 
Lilly SAE Report Form.  The detailed SAE reporting process will be provided to the sites in the 
SAE reporting guidelines contained in the Study Reference Manual.
Investigators must report SAEs and follow-up information to their responsible IRB according to 
the policies of the responsible IRB.

13.1
Institutional Review Board Approval
The clinical study protocol, ICF, IB, available safety information, patient documents (e.g., study 
diary), patient recruitment procedures (e.g., advertisements), information about payments (i.e., 
Principal Investigator payments) and compensation available to the patients and documentation 
evidencing the Principal Investigator’s qualifications should be submitted to the IRB for ethical 
review and approval if required by local regulations, prior to the study start.
The Principal Investigator/Sponsor and/or designee will follow all necessary regulations to 
ensure appropriate, initial, and on-going, IRB study review.  The Principal Investigator/Sponsor 
(as appropriate) must submit and, where necessary, obtain approval from the IRB for all 
subsequent protocol amendments and changes to the informed consent document.  Investigators 
will be advised by the Sponsor or designee whether an amendment is considered substantial or 
non-substantial and whether it requires submission for approval or notification only to an IRB.
Safety updates for LY3023414, will be prepared by the Sponsor or its representative as required, 
for distribution to the investigator(s) and submission to the relevant IRB.
13.2
Regulatory Approval
As required by local regulations, the Sponsor will ensure all legal aspects are covered, and 
approval of the appropriate regulatory bodies obtained, prior to study initiation.  If required, the 
Sponsor will also ensure that the implementation of substantial amendments to the protocol and 
other relevant study documents happen only after approval by the relevant regulatory authorities.
13.3
Informed Consent
Informed consent is a process by which a patient voluntarily confirms his or her willingness to 
participate in a particular study after having been informed of all aspects of the study that are 
relevant to the patient's decision to participate.  Informed consent is documented by means of a 
written, signed, and dated informed consent form.
The informed consent form will be submitted for approval to the IRB that is responsible for 
review and approval of the study.  Each consent form must include all of the relevant elements 
currently required by the relevant regulatory authorities, as well as local county authority or state 
regulations and national requirements.
Before recruitment and enrollment into the study, each prospective candidate will be given a full 
explanation of the research study.  Once the essential information has been provided to the 
prospective candidate, and the investigator is sure that the individual candidate understands the 
implications of participating in this research study, the candidate will be asked to give consent to 
participate in the study by signing an informed consent form.  A notation that written informed 
consent has been obtained will be made in the patient’s medical record.  A copy of the informed 
consent form, to include the patient’s signature, will be provided by the investigator to the 
patient.
If an amendment to the protocol substantially alters the study design or the potential risks to the 
patients, the patient’s consent to continue participation in the study should be obtained.

Confidentiality
13.3.1
13.3.1.1
Patient Confidentiality
Confidentiality of patient’s personal data will be protected in accordance with the Health 
Insurance Portability and Accountability Act of 1996 (HIPAA).  HIPAA regulations require that, 
in order to participate in the study, a patient must sign an authorization form for the study that he 
or she has been informed of following:

What protected health information (PHI) will be collected from patients in this study

Who will have access to that information and why

Who will use or disclose that information

That health information may be further disclosed by the recipients of the information, and 
that if the information is disclosed the information may no longer be protected by federal 
or state privacy laws

The information collected about the research study will be kept separate from the 
patient’s medical records, but the patient will be able to obtain the research records after 
the conclusion of the study

Whether the authorization contains an expiration date

The rights of a research patient to revoke his or her authorization
In the event that a patient revokes authorization to collect or use his or her PHI, the investigator, 
by regulation, retains the ability to use all information collected prior to the revocation of patient 
authorization.  For patients that have revoked authorization to collect or use PHI, attempts should 
be made to obtain permission to collect at least vital status (i.e., that the patient is alive) at the 
end of their scheduled study period.
In compliance with ICH GCP guidelines and applicable parts of 21 CFR it is a requirement that 
the investigator and institution permit authorized representatives of Sponsor, the regulatory 
authorities and the IRB direct access to review the patient’s original medical records at the site 
for verification of study-related procedures and data. 
Measures to protect confidentiality include: only a unique study number and initials will identify 
patients in the eCRF or other documents submitted to the Sponsor.  This information, together

AMENDMENT 3: 25 January 2017
v 4.0
Page 69 of 95
The Principal Investigator and each study staff member is responsible for maintaining a 
comprehensive and centralized filing system (e.g., regulatory binder or investigator study file 
[ISF]) of all study-related (essential) documentation, suitable for inspection at any time by 
representatives from the Sponsor and/or applicable regulatory authorities.  The ISF must consist 
of those documents that individually or collectively permit evaluation of the conduct of the study 
and the quality of the data produced.  The ISF should contain as a minimum all relevant 
documents and correspondence as outlined in ICH GCP Section 8 and 21 CFR Part 312.57, 
including key documents such as the IB and any amendments, protocol and any amendments, 
signed ICFs, copies of completed CRFs, IRB approval documents, Financial Disclosure forms, 
patient identification lists, enrollment logs, delegation of authority log, staff qualification 
documents, laboratory normal ranges, records relating to the study drug including accountability 
records.  Drug accountability records should, at a minimum, contain information regarding 
receipt, shipment, and disposition.  Each form of drug accountability record, at a minimum, 
should contain Principal Investigator name, date drug shipped/received, date, quantity and 
batch/code, or lot number for identity of each shipment.  In addition, all original source 
documents supporting entries in the CRF must be maintained and be readily available.
The Sponsor shall maintain adequate investigational product records and financial interest 
records as per 21CFR Part 54.6 and Part 312.57 for no less than 2 years after the last marketing 
application has been approved by FDA; or, in the event that the marketing application has not 
been approved by FDA, for no less than 2 years after the last shipment / delivery of the drug for 
investigational use is discontinued and FDA has been notified of the discontinuation.
The IRB shall maintain adequate documentation / records of IRB activities as per 21CFR Part 
56.115 for at least 3 years after completion of the research.
The Investigator shall maintain adequate records of drug disposition, case histories, and any 
other study-related records as per 21 CFR Part 312.62 for no less than 2 years after the last 
marketing application has been approved by FDA; or, in the event that the marketing application 
has not been approved by FDA, for no less than 2 years after the last shipment / delivery of the 
drug for investigational use is discontinued and FDA has been notified that the investigation has 
been discontinued.
To enable evaluations and/or audits from regulatory authorities or from the Sponsor or its 
representative, the investigator additionally agrees to keep records, including the identity of all 
participating patients (sufficient information to link records e.g., eCRFs and medical records), all 
original, signed informed consent forms, and copies of all eCRFs, records, SAE Reporting forms, 
source documents, detailed records of treatment disposition, and related essential regulatory 
documents.  The documents listed above must be retained by the investigator for as long as 
needed to comply with national and international regulations (generally 2 years after 
discontinuing clinical development or after the last marketing approval).  Sponsor or its 
representatives will notify the investigator(s)/institutions(s) when the study-related records are no 
longer required.
If the investigator relocates, retires, or for any reason withdraws from the study, both the Sponsor 
and its representative should be prospectively notified.  The study records must be transferred to 
an acceptable designee, such as another investigator, another institution, or to the Sponsor.  The 
investigator must obtain the Sponsor’s written permission before disposing of any records, even

if retention requirements have been met.  All study files will be maintained by the Sponsor or its 
representative throughout the study.  If study files are maintained by a representative of the 
Sponsor, the study files will be transferred to the Sponsor at the conclusion of the study.
14.4
Data Collection
The study CRF is the primary data collection instrument for the study.  Case report forms will be 
completed using the English language and should be kept current to enable the Sponsor to review 
the patients’ status throughout the course of the study.
In order to maintain confidentiality, only study number, patient number, initials and date of birth 
will identify the patient in the eCRF.  If the patient’s name appears on any other document (e.g., 
laboratory report), it must be obliterated on the copy of the document to be supplied to Sarah 
Cannon Development Innovations and replaced instead with the patient number and patient’s 
initials.  The investigator will maintain a personal patient identification list (patient numbers with 
corresponding patient identifiers) to enable records to be identified and verified as authentic.  
Patient data/information will be kept confidential, and will be managed according to applicable 
local, state, and federal regulations.
All data requested by the eCRF must be supported by and be consistent with the patient’s source 
documentation.  All missing data must be explained.  When a required laboratory test, 
assessment, or evaluation has not been done or an “Unknown” box is not an option on the eCRF, 
a note should be created verifying that the field was “Not Done” or “Unknown.”  For any entry 
errors made, the error(s) must be corrected, and a note explaining the reason for change should 
be provided.
The investigator will electronically sign and date the patient CRF casebook indicating that the 
data in the CRF has been assessed.  Each completed CRF will be signed and dated by the 
Principal Investigator, once all data for that patient is final.
14.5
Disclosure and Publication Policy
All information provided regarding the study, as well as all information collected/documented 
during the course of the study, will be regarded as confidential.  The Sponsor reserves the right 
to release literature publications based on the results of the study.  Results from the study may be 
published and/or presented as per the Sponsor’s disclosure process.
Inclusion of the investigator in the authorship of any multi-center publication will be based upon 
substantial contribution to the design, analysis, int erpretation of data, drafting and/or critically 
revising any manuscript(s) derived from the study.  The investigator acknowledges that the study 
is part of a multi-center study and agrees that any publication by the investigator of the results of 
the study conducted at research site shall not be made before the first multi-center publication.  
In the event there is no multi-center publication within fifteen (15) months after the study has 
been completed or terminated at all study sites, and all data has been received, the investigator 
shall have the right to publish its results from the study, subject to the notice requirements 
described herein and subject to acknowledgement of the Sponsor as appropriate.  Investigator 
shall provide the Sponsor thirty (30) days to review a manuscript or any poster presentation, 
abstract or other written or oral material which describes the results of the study for the purpose 
only of determining if any confidential or patentable information is disclosed thereby.  If the

PK blood samples will have a window of ± 15 minutes.  PK blood samples for patients who are participating in Part A will be Day -1, pre-dose, 1.5, 3, and 6 hours post 
LY3023414 dose; Cycle 1 Day 1 pre-dose of LY3023414 and enzalutamide; Cycle 1 Day X - any day between Day 15 and Day 28, pre-dose of LY3023414 and 
enzalutamide, 1.5, 3, and 6 hours post LY3023414 dose; and Cycle 1 Day X + 1- between Day 16 and Day 29, pre-dose of LY3023414 and enzalutamide (see Table 1).  
PK blood samples for all patients will be taken pre-dose of LY3023414/placebo and enzalutamide and 1.5 hours post LY3023414/placebo dose on Cycle 2 Day 1 and 
Cycle 3 Day 1 (see Table 2).  A hematocrit value (which can be obtained from a CBC) is required within +/- 2 days of collection of sampling for PK  
j
On PK days, pre-dose measurements and dose administration will be done in a fasted state.  Patients should remain fasted for 1 hour post- dose.
k
Patients will be restaged prior to Cycle 3 and after every 2 cycles of treatment thereafter (every 8 weeks).  Patients with progressive disease or unacceptable toxicity 
should be discontinued from treatment; patients with stable disease or response to therapy will continue treatment.
l
PSA blood samples will be taken ≤4 weeks prior to initiation of treatment, on Week -1 Day -7 for Part A patients, Cycle 1 Day 1 (unless collected within the previous 72 
hours) Day 1 of every cycle, and at the End of Study visit if not taken in the previous 4 weeks.  Patients with PSA progression are allowed and encouraged to continue 
treatment until symptomatic or radiographic progression.
m
Bone scans- technetium only - ≤4 weeks prior to initiation of treatment, prior to Cycle 3 and after every 2 cycle s of treatment thereafter, and at the End of Study visit if 
scans were not taken in the previous 8 weeks.  Bone lesions should be evaluated using PCWG2 criteria and not RECIST v 1.1. 
n
CT scans of the chest, abdomen and pelvis ≤4 weeks prior to initiation of treatment.  CT scan of the chest should be repeated only if abnormal at baseline. CT scans of 
the abdomen and pelvis should be taken prior to Cycle 3 and after every 2 cycles of treatment thereafter, and at the End of Study visit (if scans were not taken in the 
previous 8 weeks).  Lymph nodes should be evaluated using PCWG2 criteria and not RECIST v 1.1.
o
Part A patients do not receive a placebo.
p
Only Part A patients come in on Cycle 1 Day 15.
q
After patients complete therapy or are discontinued from treatment they will visit the study center 30 days (+3) after finishing treatment for end of treatment assessments.  
Patients must be followed for AEs for 30 calendar days after the last dose of study drug.
r
Patients who discontinue study treatment prior to the occurrence of disease progression will be followed every 2 months (±2 weeks) from the date of last dose of study 
drug until disease progression or for up to 3 years whichever comes first.  
s
The PGx sample should be collected C1D1. If the sample is not able to be collected C1D1, it can be collected anytime during C1 or C2.  The PGx sample is part of the 
Biomarker sample and does not require a separate kit.
