The Association Between HSD3B1 Genotype and Steroid 
Metabolism in Normal and Prostate Cancer Tissue of Men with 
Intermediate and High-risk Prostate Cancer Undergoing Radical 
Prostatectomy after a short-term treatment with Apalutamide 
and leuprolide acetate. 
Study Phase 
Phase II Study 
Brief Background/Rationale 
 
 
 
As homozygosity for HSD3B1(1245C) SNP can impact response 
and mediate resistance to androgen deprivation therapy (ADT), 
evaluating the effect of such genotype variation on the level of 
steroid metabolites and the intratumoral DHT concentration in 
benign and tumor tissue of men receiving a short course of 
Apalutamide and leuprolide acetate prior to undergo RP is of 
significant interest. We hypothesize that patients with 
homozygous HSD3B1 (1245C) inheritance that leads to a gain of 
function in 3βHSD1, will have a sustained androgen synthesis 
from extragonadal precursor steroids and higher concentrations 
of DHT compared to patients with wild-type HSD3B1 (1245A) 
inheritance in the context of testosterone suppression. In 
addition, it is expected that heterozygous HSD3B1 (1245C) 
patients will have intermediate levels of DHT. We also 
hypothesize that treatment with Apalutamide will reverse the 
effects of elevated DHT on AR signaling in benign and malignant 
prostate tissue.  For example, although DHT concentrations will 
be higher in the HSD3B1 (1245C) groups, PSA expression will 
likely be similar among all groups.  We anticipate that these 
studies will serve as the first step in identifying patients with 
localized and locally advanced prostate cancer who will benefit 
from upfront treatment with Apalutamide in addition to medical 
castration prior to undergo local definitive therapy with surgery.

Sample Size 
Based on the known frequency of the genotypes in question, 
approximately 120 male patients will be genotyped prior to 
enrollment on study. The sample size required to carry-out the 
objectives of the study will be 57 male patients. Due to logistical 
restrictions, an accrual goal of 80 male patients may be needed 
in order to capture all objectives to support this sample size. 
There won’t be any ethnic restrictions for study entry including 
during the initial genotype identification state.

Introduction   
1.1 Prostate Adenocarcinoma  
Prostate cancer represents 14.0% of all new cancer cases in the U.S. It is the second most common 
cause of cancer death in American males and the leading cause of cancer death in males over 85. In 
2015, it is estimated that there will be 220,800 new cases of prostate cancer and an estimated 27,540 
people will die of this disease.1 Androgen deprivation therapy (ADT), with either medical or surgical 
castration, is a critical and the most effective component of therapy for patients with metastatic or high-
risk localized prostate cancer. Normally, serum testosterone (T) is irreversibly converted to DHT in the 
prostate by steroid 5α-reductase (SRD5A). Dihydrotestosterone (DHT) is the chief endogenous agonist 
for the androgen receptor (AR) and binds and activates AR with 10-fold higher potency than T. ADT 
lowers serum T concentrations to less than 1.7 nmol/l and generates an initial tumor response in about 
90% of the patients. However, nearly all patients will eventually progress to a “castration-resistant” 
state.   
Castration-resistant prostate cancer (CRPC) is often manifested by rising levels of prostate-specific 
antigen (PSA), progressive disease on imaging studies, worsening of symptoms and ultimately death.2,3 It 
is well known that the AR continues to play a major role in disease progression in a large majority of 
cases, as demonstrated by the level of AR overexpression in castration-resistant tumor tissue and the 
level of expression of the AR regulated gene, PSA.4 In vitro growth of a metastatic prostate cancer cell 
line, LNCaP cells, maintained physiologic levels of intracellular DHT (10 nM) and proliferated despite 
castrate levels of testosterone in the media.5 Moreover, clinical studies have clearly demonstrated 
significantly higher levels of intra-tumoral androgens in CRPC from anorchid men compared with 
primary prostate tumors from untreated eugonadal men.6 As clinically demonstrated, adding a 
secondary hormonal therapy to further reduce androgen synthesis or directly inhibit AR can lead to 
declines in PSA level and disease control in CRPC. This points to the importance of intratumoral 
androgens in driving tumor progression in CRPC.7–9 Emerging evidence also demonstrates that AR can be 
activated in a ligand-independent fashion by growth factors or cytokines working independently or in 
combination.4,10 Changes in the level of ligand(s) in tumor tissue, increased levels of the protein due to 
gene amplification, activating mutations in the receptor, and changes in co-regulatory molecules are 
some of the proposed mechanisms behind the development of castration-resistant disease that are just 
beginning to unfold.11–14   
1.2 Apalutamide 
Apalutamide is an orally available, non-steroidal selective antagonist of the androgen receptor (AR). 
Apalutamide was recently FDA approved for the treatment of metastatic castration sensitive prostate 
cancer and non-metastatic castration-resistant prostate cancer, however, Apalutamide is still considered 
investigational because of its use prior to surgery. Apalutamide directly antagonizes the binding of 
androgen to the ligand-binding domain of the AR, impairing nuclear translocation and DNA binding. 
Apalutamide binds the AR with 5-fold greater affinity than the first-generation anti-androgen 
bicalutamide. Apalutamide is currently being developed for the treatment of both hormone-sensitive 
and castration-resistant prostate cancer (CRPC).

Clinical Studies with Apalutamide 
Study ARN-509-001 is an ongoing Phase 1/2 study in subjects with progressive CRPC. In the Phase 1 
component of the study, 30 subjects with metastatic CRPC (mCRPC) received at least 1 dose of 
Apalutamide at escalating dose levels ranging from 30 to 480 mg/day. All subjects received Apalutamide 
orally once daily, except those in the 300-, 390-, and 480-mg cohorts who received a twice-daily dosing 
regimen. There was 1 dose-limiting toxicity (DLT) observed at the 300-mg dose level (Grade 3 treatment-
related abdominal pain).26 The event lasted 6 days and resolved with dose interruption and subsequent 
dose reduction to 240 mg (120 mg twice daily). Three additional subjects were treated at the 300-mg 
dose level with no reported DLTs. No seizures were reported at any dose level. The maximum tolerated 
dose (MTD) was not determined. The pharmacokinetics (PK) profile was determined to be linear and 
dose-proportional15. The dose of 240 mg was chosen as the dose for subsequent phase III studies. 
 
Ninety-seven subjects are being evaluated in the Phase 2 portion (Cohort 1: non-metastatic [NM]-CRPC 
n=51; Cohort 2: mCRPC without previous ketoconazole, abiraterone acetate/prednisone, enzalutamide 
or chemotherapy [for mCRPC] n=25; and Cohort 3: mCRPC post abiraterone acetate/prednisone and no 
previous chemotherapy [for mCRPC] n=21). Treatment-related adverse events (AEs) in the Phase 2 
portion that have been reported to date in >10% of the subjects across the 3 cohorts included fatigue, 
diarrhea, nausea, abdominal pain, hot flush, hypothyroidism, decreased blood thyroid stimulating 
hormone, dysgeusia, decreased appetite (including weight loss), and skin rashes. In the Phase 2 portion, 
no serious adverse events (SAEs) were assessed as treatment-related. The safety profile of Apalutamide 
is consistent with the preclinical pharmacology and toxicology, and is as expected for an AR antagonist. 
 
Apalutamide demonstrated prostate-specific antigen (PSA) reductions of ≥50% at 12 weeks of 89% for 
Cohort 1, 88% for Cohort 2, and 22% for Cohort 3. Similar data were observed after 24 weeks for 
Cohorts 1 and 2. The time to PSA progression was 24 months (95% confidence interval [CI]: 16.3, NE [not 
estimable] for Cohort 1), 18 months (95% CI: 8.3, NE) for Cohort 2, and 3.7 months (95% CI: 2.8, 5.6) for 
Cohort 3. These data indicate that Apalutamide demonstrates efficacy and an acceptable safety profile 
in both NM-CRPC and mCRPC patients. 
 
Study Apalutamide-003 was a Phase 3 study of Apalutamide compared with placebo for the treatment 
of subjects with high-risk (defined as a PSA doubling time ≤10 months) NM-CRPC. Among men with 
nonmetastatic castration-resistant prostate cancer, metastasis-free survival and time to symptomatic 
progression were significantly longer with apalutamide than with placebo.  Study 56021927PCR3001 
was a Phase 3 study of Apalutamide plus abiraterone acetate and prednisone compared with 
abiraterone acetate and prednisone for the treatment of subjects with chemotherapy-naïve mCRPC.  No 
clinical results are available for this study.

1.3 
Leuprolide Acetate 
Leuprolide is an agonist of gonadotropin releasing hormone (GnRH). Acting as a potent inhibitor of 
gonadotropin secretion; continuous administration results in suppression of ovarian and testicular 
steroidogenesis due to decreased levels of LH and FSH with subsequent decrease in testosterone (male) 
and estrogen (female) levels. In males, testosterone levels are reduced to below castrate levels. 
Leuprolide may also have a direct inhibitory effect on the testes, and act by a different mechanism not 
directly related to reduction in serum testosterone.  
 
1.3.1 Clinical Use of Leuprolide in Prostate Cancer 
The objective of ADT (with any of the available GnRH  agonists- in this case Leuprolide) is to lower the 
serum testosterone level at least to the same extent as that achieved with surgical orchiectomy. 
Historically, this has correlated with a level of 1.7 nmol/L (<50 ng/dL), although contemporary laboratory 
testing indicates that testosterone levels decline to 0.7 nmol/L (<20 ng/dL) after orchiectomy. The 
potential relationship between suppression of the serum testosterone and clinical outcome is illustrated 
by a secondary analysis of the JPR.7 trial in which 626 evaluable men were treated with continuous ADT 
for a rising PSA and followed for a median of eight years [Crook J, et al. NEJM 2012; 367(10):895, Klotz L, 
et al. JCO 2015; 33(10):1151] The risk of dying was lowest in those with the greatest suppression of 
serum testosterone in the first year. Compared with a first year minimum testosterone nadir <0.7 
nmol/L, those with a nadir testosterone of 0.7 to 1.7 nmol/L had an increased risk of dying (hazard ratio 
[HR] 2.08, 95% CI 1.28-3.38), as did those a nadir >1.7 nmol/L (HR 2.93, 95% CI 0.77-4.70). Although 
timing to initiation of therapy remains controversial, ADT is the standard of care for men with advanced 
disease. ADT in combination with radiation therapy is commonly utilized in men undergoing RT as local 
definitive treatment for high-risk PCa. Similarly, ADT immediately after RP in men with positive lymph 
node disease is considered standard practice for most centers in the U.S.  
1.4 
Androgen Metabolism 
The major sites of chemical modification on the steroid backbone for DHT synthesis are carbons 3, 5 and 
17, which are modified in 3 enzymatic steps for the conversion of DHEA to DHT (Figure 1). DHEA is a 3β-
hydroxy, Δ5 steroid (double bond between carbons 5 and 6) and is enzymatically converted in CRPC 
tissues to Δ4-androstenedione (AD) by 3βHSD. 3βHSD1 and 3βHSD2 are the two human isoenzymes that 
possess this enzymatic activity.16,17 3βHSD1 is thought to be the peripherally expressed isoenzyme and 
3βHSD2 the isoenzyme in steroidogenic organs.17 However, both are detected in CRPC.6,18 We have 
previously shown that 3βHSD enzymatic activity is absolutely required for the synthesis of T and/or DHT, 
downstream AR nuclear translocation, expression of AR-responsive genes and CRPC growth.19 It was 
generally thought that AD undergoes conversion to T, which is then converted to DHT by SRD5A.20,21 
However, we have recently shown that an alternative pathway is dominant, not only in cell line models 
but also in freshly collected tumors from patients with CRPC. In this pathway, SRD5A converts AD to 5α-
androstanedione (5α-dione), which is then converted to DHT.22 Furthermore, we have shown that only 
one of two SRD5A isoenzymes, SRD5A1, is specifically required in this pathway. We have also 
demonstrated that a pitfall of pharmacologically blocking SRD5A with dutasteride is that AD is instead

diverted to increased synthesis of T, compensating in part for depletion of the more potent DHT22, 
resulting in modest clinical activity of SRD5A inhibition against CRPC23. 
Figure 1. Synthesis of DHEA from cholesterol in the adrenal and metabolism of DHEA to intratumoral 
androgens in CRPC. Formation of testosterone and/or dihydrotestosterone from adrenal DHEA requires 
enzymatic modification of the 3-, 5-, and 17-postions of the steroid backbone by 3βHSD, SRD5A and 17βHSD 
isoenzymes. The dominant route of dihydrotestosterone synthesis is independent of testosterone (wide green 
arrows). Dihydrotestosterone is converted to the inactive metabolites androstanediol and androsterone by 
3αHSD. De novo steroidogenesis through the “backdoor” pathway still requires 3β-hydroxyl-oxidation and Δ5-
isomerization of the cholesterol backbone by 3βHSD.

1.5 Preclinical Data  
Recently, a gain of function single-nucleotide polymorphism (SNP) in HSD3B1(1245C; N367T) was 
identified that can also occur as a somatic mutation in CRPC tumors.24 Germline SNP variant of 
HSD3B1(1245C, rs1047303) occurs with a reported allele frequency of 22% in general population, but 
appears to vary widely by ethnicity.25 In a group of 118 prostate cancer patients at Cleveland Clinic, the 
frequency of the variant HSD3B1(1245C) allele is 36%.26 3β-hydroxysteroid dehydrogenase isoenzyme-1 
(3βHSD1), encoded by HSD3B1, is one of the three enzymes involved in converting DHEA from the 
adrenal gland to DHT in prostate cancer tissue.22 3βHSD oxidizes 3β-hydroxyl to 3-keto and isomerizes Δ5 
to Δ4 in the process of converting DHEA to AD. These reactions together make this step practically 
irreversible by an enzyme that is required for all possible pathways that lead to the synthesis of DHT. 
Chang et al have shown that CRPC sometimes expresses the 367T form of the HSD3B1, which increases 
metabolic flux from DHEA via the 5α-dione pathway to DHT by protein resistance to ubiquitination and 
degradation rather than increased catalytic activity. This mutation increases protein half-life from 2.1 to 
27 hours which leads to a profound accumulation of 3βHSD1 with subsequent increased flux to DHT and 
ultimately increased AR activation and prostate cancer progression.24 In addition, to study the possibility 
of HSD3B1 (1245C) selection in human tumors, we sequenced matching germline and tumor DNA from 
40 men with CRPC. Among these patients, the germline of 25, 11, and 4 individuals was homozygous 
wild type HSD3B1 (1245A), heterozygous, and homozygous variant HSD3B1 (1245C), respectively. Three 
of 25 (12%) CRPC tumors with homozygous HSD3B1 (1245A) inheritance have acquired the HSD3B1 
(1245C) allele. Also, three of 11 (27%) CRPC tumors with heterozygous inheritance, have loss of 
heterozygosity (LOH) of the HSD3B1 (1245A) allele, resulting in the HSD3B1 (1245C) allele being 
predominantly detectable. In contrast, none of the 11 cases with heterozygous inheritance exhibited 
LOH of the HSD3B1(1245C) allele.24 These data support the role of the HSD3B1 (1245C) allele in the 
development of CRPC. Moreover, our review of the clinical outcomes in 118 men with prostate cancer 
who were treated with ADT for biochemical failure after prostatectomy shows that inheritance of 
HSD3B1(1245C) allele that enhances the DHT synthesis may predict resistance to ADT in prostate 
cancer.26 In this group of patients allelic frequency of HSD3B1 (1245C) was 36% with homozygous wild-
type, heterozygous, and homozygous variant detected in 37%, 53%, and 10% of the patients. We 
demonstrated that median progression free survival (PFS), distant metastasis-free survival (DMFS), and 
overall survival (OS) diminished as a function of the number of variant alleles inherited, showing a gene-
dosage effect and stepwise decrements with 0 vs. 1 vs. 2 variant alleles in all three endpoints.26   
 
1.6 Review of Relevant Prior Clinical Trials 
Based on their mechanism of action and potential utility in early stages of PCa, the use of newer agents 
like abiraterone acetate (AA) and enzalutamide in the pre-operative phase has become an attractive 
therapeutic strategy. Therefore, these agents are used in multiple studies in combination with multiple 
other agents in the neoadjuvant setting to evaluate their potential role in this setting. The clinical 
activity and safety of AA/P in the neoadjuvant setting in men undergoing RP was evaluated in two 
separate phase II studies.  The first study, a randomized phase II trial evaluated the impact of 12 weeks 
of AA/P + LHRH vs. LHRH alone in 50 high risk PCa patients (≥T1c GS ≥8, or ≥cT2b, GS≥ 7 and PSA > 

CASE 5815

Version date: July 30, 2019 
10ng/ml).27 The second trial evaluated 24 weeks of AA given in combination with LHRh in a similar group 
of patients (n=58).28 Pathologic “tumor down-staging” and treatment effect on intra-prostatic levels of 
T, DHT and other markers of androgen biosynthesis were the main objectives of the studies. This clinical 
experience suggests that neo-adjuvant therapy with AA and LHRH is well tolerated and can lead to 
significant reduction of intra-tumoral androgen production that possibly results in tumor down-staging. 
The significance of this pathologic change remains unknown. Also, an ongoing multi-center randomized 
phase II trial is evaluating the neoadjuvant use of enzalutamide alone versus enzalutamide in 
combination with dutasteride and leuprolide in men with localized high-risk prostate cancer.29      
 
1.7 Study Rationale  
As homozygosity for HSD3B1(1245C) SNP can impact response and mediate resistance to ADT, 
evaluating the effect of such genotype variation on the level of steroid metabolites and the intratumoral 
DHT concentration in benign and tumor tissue of men receiving a short course of Apalutamide and 
leuprolide prior to undergo RP is of interest. We hypothesize that patients with homozygous HSD3B1 
(1245C) inheritance that leads to a gain of function in 3βHSD1, will have a sustained androgen synthesis 
from extragonadal precursor steroids and higher concentrations of DHT compared to wild-type HSD3B1 
(1245A) inheritance in the context of castration. Also, we expect intermediate levels of DHT in the 
heterozygous HSD3B1 (1245C) group. We also hypothesize that Apalutamide will reverse the effects of 
elevated DHT on AR signaling in prostate tissue.  For example, although DHT concentrations will be 
higher in the HSD3B1 (1245C) groups, PSA expression will be equivalent among all groups.  We 
anticipate that these studies will serve as the first step in identifying patients with prostate cancer who 
will benefit from upfront treatment with Apalutamide in addition to medical castration.

Study design  
3.1 
Summary 
The primary goal of the study is to evaluate the differential effect of neo-adjuvant Apalutamide and 
leuprolide on dihydrotestosterone (DHT) concentration in benign prostate tissue based on HSD3B1 
genotype. Newly diagnosed, biopsy-proven, intermediate or high-risk prostate cancer patients (G 4+3 or 
higher, ≥T2b, PSA ≥ 10), who are candidates for radical prostatectomy (RP) are eligible to participate in 
this study. In order to have enough tumor tissue to perform all of the tests, a minimum tissue 
requirement of ≥1 positive core biopsy. All participating patients will receive a single dose of leuprolide 
7.5 mg IM in addition to Apalutamide 240 mg orally daily for four weeks prior to RP. Treatment will be 
started on day (-28) ± 3 from the scheduled RP date to minimize the variability of treatment duration. 
Apalutamide will be continued up to and including the day before radical prostatectomy. Although pre-
treatment MRIs of the prostate will be ideal, this protocol does not mandate these imaging studies for 
study enrollment. Of note, the vast majority of patients undergoing RP at our institutions undergo MRI 
of prostate for further staging purposes. Thus, the vast majority of our patients will have this completed.  
Blood will be drawn at baseline and on the day of surgery to evaluate serum PSA and androgen 
metabolite levels. After RP, fresh tissue from the surgical specimen will be sampled by the GU 
pathologist (multiple punch biopsies to increase the chance of capturing benign and tumor tissue) with 
the same methodology that we have previously described.31 All steroids will be extracted from prostate 
tissue (20 mg), derivatized by the Girard-T oxime methodology to increase sensitivity, and quantitated 
by mass spectrometry, as previously described.32  Expression of PSA transcript and protein will be 
assessed as we have performed routinely and described previously.22,24 Levels of DHT, T, DHEA, 
androstenediol, 5α-dione, AD, androsterone, and 5α-androstanediol will be measured in all specimens. 
The underlying hypothesis is that under a recessive model, homozygous HSD3B1 (1245C) is stabilizing 
and leads to a gain of function in 3βHSD1 that ultimately results in sustained androgen synthesis 
compared to wild-type HSD3B1 (1245A), after treatment with leuprolide. We expect to have 
intermediate levels of these metabolites in the heterozygous HSD3B1 (1245C) group.

6.1 Packaging, Storage, and Labeling 
 
Apalutamide will be supplied as 60mg tablets packaged in 30-ct, 120 cc HDPE bottles with child-
resistant closures and tamper proof heat induction seals. At the clinical and at the patient’s home, 
the study drug should be stored at room temperature and protected from head; do not freeze. 
Each bottle of study drug will be labeled with the required regulatory agency warning statement, 
the protocol number, and directions for patient use and storage. The Investigator will ensure that 
the study drug is stored in appropriate conditions in a secure location with controlled access. 
6.2 Dosage and Administration 
6.2.1 Description of Study agents and Administration 
Study agents include Apalutamide and leuprolide. Apalutamide will be provided by the study. Subjects 
are to receive the following:  
 
Leuprolide 7.5 mg IM x 1 dose on day (-28) ± 3 days 
 
Apalutamide 240 mg (4 x 60 mg tablets) by mouth [PO] on a continuous once-daily dosing 
regimen.  
Sufficient study medication for an entire treatment course till the day of surgery will be distributed on 
the first day of treatment. Apalutamide will be self-administered on an outpatient basis during the 
study, once daily, with or without food. Treatment will start on Day (-28) ± 3 days from the scheduled 
date for radical prostatectomy. Subjects may take Apalutamide up to and including the day before 
radical prostatectomy, at which time the medication will be discontinued.  
It is anticipated that individual patients may occasionally forget to take a dose. In those cases, missed 
doses should only be replaced if the patient remembers within a 12-hour window. After that, patients 
should just take the next dose the following day, without compensating for the missed dose.

6.3 General Concomitant Medication and Supportive Guidelines 
6.3.1 Pre-study therapy 
To be eligible for this study, subjects must have a new diagnosis of prostate cancer with no history of 
previous treatments for prostate cancer. 
6.3.2 Concomitant therapy 
All patients should be maintained on the same medications throughout the entire study period, as 
medically feasible, with minimum introduction of new chronic therapies. Standard medical treatment as 
applicable is allowed except for treatments noted in the exclusion criteria and/or listed in the prohibited 
medications section below. 
6.3.2.1 Prohibited medications and treatments 
As a class effect, androgen receptor antagonists have been associated with seizures due to an off-
target mechanism of action (GABAA inhibition).33,34    
To date, no patients receiving Apalutamide have experienced seizures, however, in preclinical 
experiments, at very high doses, dogs treated with Apalutamide had tremors and generalized 
seizures. Patients will be closely monitored for seizures, but as a precautionary measure, drugs 
known to decrease the seizure threshold and/or cause seizure will be prohibited while on study. A 
list of the medications which are PROHIBITED while on study: 
 
Aminophylline/theophylline 
 
Atypical antipsychotics (e.g., clozapine, olanzapine, risperidone, ziprasidone) 
 
Bupropion  
 
Lithium  
 
Meperidine and pethidine  
 
Phenothiazine antipsychotics (e.g., chlorpromazine, mesoridazine, thioridazine)  
 
Tricyclic and tetracyclic antidepressants (e.g., amitriptyline, desipramine, doxepin, 
imipramine, maprotiline, mirtazapine)  
 
Herbal products that may have hormonal anti-prostate cancer activity and/or are known 
to decrease PSA levels (e.g. saw palmetto). All herbal supplements must be discussed 
with the study provider and discontinued at the provider’s discretion.   
 Current systemic steroid or corticosteroid therapy (inhaled or topical steroids are 
also not allowed), unless waived at the provider’s discretion. 
 
[Please see the appendix IV for a more comprehensive list (with brand names)]   
6.3.2.2 Restricted Concomitant Medications  
 
Apalutamide is metabolized primarily by human CYP3A4, thus co-administration with strong 
inhibitors or inducers of CYP3A4 should be avoided as much as possible. Apalutamide may also 
induce CYP3A4; therefore, caution should be taken when administered in conjunction with 
CYP3A4 substrates that have a narrow therapeutic index. Examples of the strong CYP3A4 
inhibitors and inducers include the following: 

CASE 5815 
 
 
 
Page 27  
 
Version date: July 30, 2019 
o Strong CYP3A4 inhibitors: itraconazole, clarithromycin, erythromycin, diltiazem, 
verapamil, delavirdine, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, 
telithromycin, voriconazole, grapefruit juice (or grapefruits); co-administration with any of 
these agents may increase Apalutamide plasma concentrations 
o  Strong CYP inducers: phenytoin, carbamazepine, rifampin, rifabutin, rifapentin, 
phenobarbital, efavirenz, tipranivir, St. John's wort; co-administration with any of these 
agents may decrease Apalutamide plasma concentrations 
 
Apalutamide may also induce CYP3A4; therefore, caution should be taken when administered 
in conjunction with CYP3A4 substrates that have a narrow therapeutic index 
 
The potential for drug-drug interaction between Apalutamide and warfarin (e.g., Coumadin) is 
unknown at present. If a patient is taking Coumadin, re-assess PT/INR as clinically indicated and 
adjust the dose of Coumadin accordingly. 
 
Corticosteroids: due to possible resistance mechanisms which may be contributed by 
glucocorticoid receptor signaling, concurrent use of corticosteroids during the study is not 
recommended.  
 
Avoid grapefruit and pomegranate juice and/or fruits  
6.3.3 Life style guidelines 
Patients of childbearing potential must agree to practice some form of effective contraception, such as 
vasectomy, double barrier contraception, or sexual abstinence prior to entering into the study and for 6 
months following the last dose of study drug. 
There are no dietary restrictions with the exception of grapefruit and pomegranate fruits and/or juice 
while the patient is on study. Study treatment can be taken with or without food. 
6.4 Duration of Therapy 
All patients will be treated with one dose of leuprolide given IM on day (-28) ± 3 days followed by 
Apalutamide starting on day (-28) ± 3 days from the date of RP. The treatment will start on Day (-28) ± 3 
days which is set based on the scheduled date of RP and will be continued till the day of surgery.  
 
6.5 Measures of Treatment Compliance  
All patients will complete a daily diary documenting the intake of Apalutamide 
At post-op follow up visit, patients will be asked to return any remaining study drug as well as all used 
and unused study drug containers.  
Treatment compliance will be defined as the number of tablets taken divided by the expected number 
of tablets and reported as percentage. In case of dose reductions, the expected number of tablets 
should reflect the new dose level.  
Tablets that are not returned will be considered to have been taken, unless otherwise specified in the 
case report form (CRF).

6.6 
Duration of Follow up 
All patients will be evaluated within 4-8 weeks after RP to rule out any potential AEs after 
discontinuation of the treatment. Any clinically significant abnormalities persisting at the end of the 
study will be followed by the investigator until resolution or until a clinically stable endpoint is reached. 
If patient has no AEs with regards to study agents this will be the last study related follow up.

Safety Monitoring 
Thyroid stimulating hormone (TSH) should be evaluated throughout the study (with T3 and T4 done only 
if TSH is abnormal) as follows: 
• 
Cycle 1, Day (-28) or within 28 days before treatment initiation   
• 
Pre-Op Evaluation 
• 
Follow Up Visit 
 
7.2 
Apalutamide Dose Modifications in the Event of Toxicity 
 
Dose interruptions and/or reductions for each patient will be permitted provided that study 
discontinuation criteria have not been met (please see Section 9.16 End of Treatment). 
 
Patients experiencing Grade 3 treatment-related adverse events will have study drug held 
until the severity of the toxicity decreases to Grade 1 or returns to baseline. If improvement 
occurs within 7 days, dosing may be restarted at the next level dose reduction.  Exception to 
hold includes clinically insignificant lab abnormalities and hypertension, as deemed by the 
treating physician.  Events that can be mitigated with optimal treatment within 2 days of the 
occurrence do not require a dose reduction; dose may resume at previous level.  
 
Any patient experiencing a drug related Grade 4 toxicity of any duration will be permanently 
discontinued.  
 
Patients experiencing treatment-related seizure of any grade or grade (G) 4 neurotoxicity 
will have study drug permanently discontinued. 
 
At any given dose level, if patients experience gastrointestinal (GI) discomfort due to the 
number of tablets, they will be allowed to switch to a BID regimen as needed. 
 
A maximum of one dose level reduction will be allowed.  
Any patient requiring Apalutamide treatment interruption longer than 7 days during the 
treatment period will meet the criteria for end of study treatment and study 
discontinuation.

ͺǤʹ Leuprolide 
Leuprolide acetate is a synthetic nonapeptide analog of naturally occurring gonadotropin releasing 
hormone (GnRH or LH-RH). The analog possesses greater potency than the natural hormone. The 
chemical name is 5-oxo-L-prolyl-L-histidyl-L-tryptophyl-L-seryl-L-tyrosyl-D-leucyl-L-leucyl-L-arginyl-
N-ethyl-L-prolinamide acetate (salt) with the following structural formula 
 
 
Leuprolide acts as an agonist at pituitary GnRH receptors. By interrupting the normal pulsatile 
stimulation of, and thus desensitizing, the GnRH receptors, it indirectly downregulates the 
secretion of gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH), 
leading to hypogonadism and thus a dramatic reduction in estradiol and testosterone levels in both 
sexes. 
 
LUPRON INJECTION is a sterile, aqueous solution intended for subcutaneous injection. It is available 
in a 2.8 mL multiple-dose vial containing leuprolide acetate (5 mg/mL), sodium chloride, USP (6.3 
mg/mL) for tonicity adjustment, benzyl alcohol, NF as a preservative (9 mg/mL), and water for 
injection, USP. The pH may have been adjusted with sodium hydroxide, NF and/or acetic acid, NF. 
 
As Lupron is a standard treatment for the management of prostate cancer. All patients will receive 
this agent according to institutional guidelines. 
 
Pharmacodynamics and Pharmacokinetics 
Onset of action: Following transient increase, testosterone suppression occurs in ~2-4 weeks of 
continued therapy. 
Distribution: Males: Vd: 27 L  
Protein binding: 43% to 49%  
Metabolism: Major metabolite, pentapeptide (M-1)  
Bioavailability: SubQ: 94%  
Excretion: Urine (<5% as parent and major metabolite)

Adverse Events and Potential Risks  
9.1 
Management of Safety Data 
This Study has been designated as an interventional study.  As such, all adverse events regardless of 
causality and special situations excluding those from subjects not exposed to a Janssen Medicinal 
Product and product quality complaints with or without an adverse event as described in this Exhibit will 
be reported from the time a subject has signed and dated an Informed Consent Form (ICF) until 
completion of the subject’s last study-related procedure (which may include contact for follow-up 
safety).  Serious adverse events will be reported for 30 days after the last dose of study drug. 
For the purposes of this study, the Janssen medicinal product is Apalutamide.  
9.2 
Definitions  
9.2.1 
Adverse Event (AE) 
An adverse event is any untoward medical occurrence in a clinical study subject administered a 
medicinal (investigational or non-investigational) product. An adverse event does not necessarily 
have a causal relationship with the treatment. An adverse event can therefore be any unfavorable 
and unintended sign (including an abnormal finding), symptom, or disease temporally associated 
with the use of a medicinal (investigational or non- investigational) product, whether or not related 
to that medicinal (investigational or non-investigational) product. (Definition per International 
Conference on Harmonisation [ICH]) 
This includes any occurrence that is new in onset or aggravated in severity or frequency from the 
baseline condition, or abnormal results of diagnostic procedures, including laboratory test 
abnormalities. 
 
Surgical AEs such as urinary incontinence, erectile dysfunction and wound complications will be 
assessed per institutional guidelines. These will not be captured as part of treatment related AEs. 
 
9.2.2 
Adverse Events of Special Interest 
Adverse events of special interest are events that the COMPANY is actively monitoring as a result 
of a previously identified signal (even if non-serious). 
 
There are no adverse events of special interest identified for apalutamide. 
 
 
 
 
 
 

CASE 5815 
 
 
 
Page 33  
 
Version date: July 30, 2019 
9.2.3 
 Identified Individual Case Safety Report (ICSR) 
A valid ICSR must contain the four minimum criteria required to meet regulatory reporting 
requirements. 
• An identifiable subject (but not disclosing personal information such as the subject’s name, 
initials or address) 
• An identifiable reporter (investigational site) 
• A Janssen medicinal product 
• An adverse event, outcome, or certain special situations 
 
The minimum information required is: 
• Suspected Janssen medicinal product (doses, indication) 
• Date of therapy (start and end date, if available) 
• Batch or lot number, if available 
• Subject details (subject ID and country) 
• Gender 
• Age at AE onset 
• Reporter ID 
• Adverse event detail (AE verbatim in English), onset date, relatedness, causality, action taken, 
outcome, (if available) 
• Janssen protocol ID 
 
9.2.4 
Product Quality Complaint (PQC) 
A product quality compliant is defined as any suspicion of a product defect related to a potential 
quality issue during manufacturing, packaging, release testing, stability monitoring, dose 
preparation, storage or distribution of the product, or delivery system.  Not all PQCs involve a 
subject.  Lot and batch numbers are of high significance and need to be collected whenever 
available. 
 
Examples of PQC include but not limited to: 
• Functional Problem: e.g., altered delivery rate in a controlled release product 
• Physical Defect:  e.g. abnormal odor, broken or crushed tablets/tablets 
• Suspected Contamination 
• Suspected Counterfeit 
 
9.2.5 
Serious Adverse Event (SAE) 
A serious adverse event based on ICH and EU Guidelines on Pharmacovigilance for Medicinal 
Products for Human Use is any untoward medical occurrence that at any dose: 
 
 Results in death.  
 Is a life-threatening adverse experience.  The term life-threatening in the definition of serious 
refers to an adverse event in which the subject was at risk of death at the time of the event.  It 

CASE 5815 
 
 
 
Page 34  
 
Version date: July 30, 2019 
does not refer to an adverse event which hypothetically might have caused death if it were 
more severe.  
 Requires inpatient hospitalization or prolongation of existing hospitalization for AEs related 
to study drug and not for the scheduled radical prostatectomy.  Any adverse event leading to 
hospitalization or prolongation of hospitalization will be considered as Serious, UNLESS at 
least one of the following expectations is met: 
o The admission results in a hospital stay of less than 24 hours OR 
o The admission is pre-planned (e.g., elective or scheduled surgery arranged prior 
to the start of the study) OR 
o The admission is not associated with an adverse event (e.g., social 
hospitalization for purposes of respite care. 
o However it should be noted that invasive treatment during any hospitalization 
may fulfill the criteria of “medically important” and as such may be reportable 
as a serious adverse event dependent on clinical judgment.  In addition where 
local regulatory authorities specifically require a more stringent definition, the 
local regulation takes precedent.  
 Results in persistent or significant disability/incapacity.  The definition of disability is a 
substantial disruption of a person’s ability to conduct normal life’s functions. 
 Is a congenital anomaly/birth defect.  
 Is a suspected transmission of any infectious agent via a medicinal product. 
 Is an important medical event.  Important medical events that may not result death, be life-
threatening, or require hospitalization may be considered a serious adverse experience when, 
based upon appropriate medical judgment, they may jeopardize the subject and may require 
medical or surgical intervention to prevent one of the outcomes listed in this definition.  
Examples of such medical events include allergic bronchospasm requiring intensive treatment 
in an emergency room or at home, blood disease or disorders, or convulsions that do not 
result in inpatient hospitalization, or the development of drug dependency or drug abuse. The 
development of a new cancer is always considered an important medical event. 
 
NOTE: DEATH FOR ANY REASON SHOULD BE REPORTED AS A SERIOUS ADVERSE EVENT WITHIN 
30-DAYS OF THE LAST DOSE OF APALUTAMIDE AS STATED IN SECTION 9.2.5.2. 
 
SAE reports and any other relevant safety information are to be emailed to Dr. Garcia at 
garciaj4@ccf.org and to the Cleveland Clinic SAE inbox at cancersaeinbox@ccf.org. 
 
SAE reports and any other relevant safety information are also to be sent to the COMPANY 
(Janssen Research & Development, LLC) within 24 hours via secure email at IIS-BIO-VIRO-
GCO@its.jnj.com as described in sections 9.7.1 and 9.9.  
 
 

CASE 5815

Version date: July 30, 2019 
9.2.5.1 Hospitalization 
For reports of hospitalization, it is the sign, symptom or diagnosis which led to the hospitalization 
that is the serious event for which details must be provided. 
 
Any event requiring hospitalization or prolongation of hospitalization that occurs during the study 
must be reported as a serious adverse event, except hospitalizations for the following: 
• Hospitalizations not intended to treat an acute illness or adverse event (e.g., social reasons such 
as pending placement in long-term care facility) 
• Surgery or procedure planned before entry into the study. [Note: Hospitalizations that were 
planned before the start of data collection and where the underlying condition for which the 
hospitalization was planned has not worsened will not be considered serious adverse events. Any 
adverse event that results in a prolongation of the originally planned hospitalization is to be 
reported as a new serious adverse event.] 
 
9.2.5.2 Life-Threatening Conditions 
The cause of death of a subject in a study within 30-days of the last dose of Apalutamide whether 
or not the event is expected or associated with the study drug, is considered a serious adverse 
event. 
 
Disease progression should not be recorded as an adverse event or serious adverse event term; 
instead, signs and symptoms of clinical sequelae resulting from disease progression/lack of efficacy 
will be reported if they fulfill the serious adverse event definition. 
 
9.3 
Unlisted (Unexpected) Adverse Event/Reference Safety Information 
An adverse event is considered unlisted if the nature or severity is not consistent with the applicable 
product reference safety information. For a medicinal product(s) with a marketing authorization, the 
expectedness of an adverse event will be determined by whether or not it is listed in the applicable 
product information.  
 
For Apalutamide, the expectedness of an adverse event will be determined by whether or not it is listed 
in the applicable product information.  
For Apalutamide, the link to the package insert is:

information/ERLEADA-pi.pdf 
   
 
9.4 
Special Reporting Situations  
Safety events of interest for a Janssen medicinal product that require expediting reporting and/or safety 
evaluation include, but are not limited to: 
• Drug exposure during pregnancy (maternal and paternal) 

CASE 5815 
 
 
 
Page 36  
 
Version date: July 30, 2019 
• Overdose of a Janssen medicinal product 
Exposure to a Janssen medicinal product from breastfeeding  
• Suspected abuse/misuse of a Janssen medicinal product 
• Inadvertent or accidental exposure to a Janssen medicinal product  
• Medication error involving a Janssen medicinal product (with or without patient exposure to the 
Janssen medicinal product, e.g., name confusion) 
• Suspected transmission of any infectious agent via administration of a medicinal product 
 
These safety events may not meet the definition of an adverse event; however, from Janssen 
Scientific Affairs perspective, they are treated in the same manner as adverse events. Special 
situations should be recorded on the Adverse Event page of the CRF. 
 
Any special situation that meets the criteria of a serious adverse event should be recorded on a 
Serious Adverse Event Report Form and be reported to Janssen Scientific Affairs within 24 hours of 
becoming aware of the event. 
 
9.5 
Pregnancy 
Because the Janssen medicinal product may have an effect on sperm, pregnancies in partners of male 
subjects exposed to a Janssen medicinal product will be reported by the PRINCIPAL INVESTIGATOR 
within 24 hours of their knowledge of the event using the Serious Adverse Event Form.  Depending on 
local legislation this may require prior consent of the partner. 
 
Follow-up information regarding the outcome of the pregnancy and any postnatal sequelae in the infant 
will be required. 
 
9.6 
Maintenance of Safety Information 
All safety data should be maintained in a clinical database in a retrievable format. The INSTITUTION and 
PRINCIPAL INVESTIGATOR shall provide all adverse events, both serious and non-serious, in report 
format. However, in certain circumstances more frequent provision of safety data may be necessary, 
e.g. to fulfill a regulatory request, and as such the data shall be made available within a reasonable 
timeframe at Janssen Scientific Affairs’ request. 
 
9.7 
Procedures for Reporting Safety Data and Product Quality Complaints (PQCs) for Janssen  
Medicinal Products to the COMPANY 
 
All adverse events and special situations whether serious or non-serious, related or not related, 
following exposure to a Janssen medicinal product are to be documented by the investigator 
and recorded in the CRF and in the subject’s source records. Investigators must record in the 
CRF their opinion concerning the relationship of the adverse event to a Janssen medicinal 
product.  
 

CASE 5815 
 
 
 
Page 37  
 
Version date: July 30, 2019 
All (serious and non-serious) adverse events reported for a Janssen medicinal product should be 
followed up in accordance with clinical practice. 
 
9.7.1 SAEs and Special Reporting Situations 
All serious adverse events that have not resolved by the end of the study, or that have not 
resolved upon discontinuation of the subject's participation in the study, must be followed 
until any of the following occurs: 
 The event resolves 
 The event stabilizes 
 The event returns to baseline, if a baseline value/status is available 
 The event can be attributed to agents other than the study drug or to factors unrelated 
to study conduct 
 It becomes unlikely that any additional information can be obtained (subject or health 
care practitioner refusal to provide additional information, lost to follow-up after 
demonstration of due diligence with follow-up efforts) 
 
 The INSTITUTION and the PRINCIPAL INVESTIGATOR will transmit all SAEs and special 
situations following exposure to a Janssen product under study in a form provided by the 
COMPANY within 24-hours of becoming aware of the event(s).  
 
 All follow-up information for serious adverse events that are not resolved at the end of 
the study or by the time of patient withdrawal must be reported directly by the PRINCIPAL 
INVESTIGATOR, within 24 hours becoming aware, to the COMPANY using the COMPANY’s 
Serious Adverse Event Report.  
 
 All available clinical information relevant to the evaluation of a related SAE, serious ADR 
or special situation is required. 
 
 The INSTITUTION and/or PRINCIPAL INVESTIGATOR are responsible for ensuring that 
these cases are complete and if not are promptly followed-up. A safety report is not 
considered complete until all clinical details needed to interpret the case are received. 
Reporting of follow-up information should follow the same timeline as initial reports. 
 
 Copies of any and all relevant correspondences with regulatory authorities and ethics 
committees regarding any and all serious adverse events, irrespective of association with 
the Janssen Product under study, are to be provided to the COMPANY within 24 hours of 
such report or correspondence being sent to applicable health authorities. 
 
9.7.2 Non-Serious AEs 
All non-serious adverse events should be reported to COMPANY according to the timeframe 

CASE 5815 
 
 
 
Page 38  
 
Version date: July 30, 2019 
outlined in the Research Funding Agreement section entitled Reporting of Data.

only be reported as instructed below.  The electronic FDA SAE reporting forms should not be 
used.   
 
9.7.3 PQC Reporting 
A PQC may have an impact on the safety and efficacy of the product. Timely, accurate, and 
complete reporting and analysis of PQC information from studies are crucial for the 
protection of patients, investigators, and the COMPANY, and are mandated by regulatory 
agencies worldwide. The COMPANY has established procedures in conformity with 
regulatory requirements worldwide to ensure appropriate reporting of PQC information. Lot 
and/or Batch #s shall be collected or any reports failure of expected pharmacological action 
(i.e., lack of effect). The product should be quarantined immediately and if possible, take a 
picture. 
 
All initial PQCs involving a Janssen medicinal product under study must be reported to the 
COMPANY by the PRINCIPAL INVESTIGATOR within 24 hours after being made aware of the 
event.  
 
If the defect for a Janssen medicinal product under study is combined with either a serious 
adverse event or non-serious adverse event, the PRINCIPAL INVESTIGATOR must report the PQC 
to the COMPANY according to the serious adverse event reporting timelines.  A sample of the 
suspected product should be maintained for further investigation if requested by the COMPANY. 
 
9.8 
Reporting Procedures for Reporting Safety Data and Product Quality Complaints (PQCs) for  
Non-Janssen Medicinal Products  
 
For SAEs, special reporting situations and PQCs following exposure to a non-Janssen medicinal 
product under study, the PRINCIPAL INVESTIGATOR should notify the appropriate 
regulatory/competent authority or the manufacturer of that medicinal product (in the absence 
of appropriate local legislation) as soon as possible.

10 Tissue Studies 
10.1 Tissue Procurement  
Radical prostatectomy tissue will be processed in a standardized fashion according to institutional 
protocols established by the Specimen Core.  Immediately after removal, prostatectomy specimens will 
be transferred into sterile ice-cold slurry of normal saline. Specimens will be accessioned and assigned a 
research number by the Tumor Procurement Service and tissue for study will be harvested according to 
standard protocols established and described in the Specimen Core and processed for pathological 
analysis as per established standards. Once harvested, the tissue to be used for this study will be snap 
frozen in liquid nitrogen and stored at -80 degrees until required for the planned analysis. All study 
related tissue (after official pathology review) will be stored within the GU core pathology department 
following standard institutional procedures and policies. Access to study tissue will be granted to 
appropriate personnel listed in the study protocol. 
 
10.2 HSD3B1 genotyping 
10.2.1 
HSD3B1 Genotyping By Sequencing 
Genomic DNA will be prepared from peripheral blood using DNeasy Blood and Tissue Kit (QIAGEN, 
Germantown, MD). HSD3B1 genotyping will be determined through a melting curve analysis on an 
ABI 7500 Real Time PCR System (Applied Biosystem, Carlsbad, CA). To determine genotype of 
HSD3B1, primer set ( Forward: 5’-GTCAAATAGCGTATTCACCTTCTCTTAT-3’ and Reverse 5’- 
GAGGGTGGAGCTTGATGACATCT-3’) and  probe (GGAGA+ACCTGAAGTCCAAGACTCAGTGATTAAGG) 
will be used. The assay will consist of an initial denaturing set at 95̊C for 2m, followed by 
amplification for 60 cycles of 95̊C for 30s, 66̊C for 30s and 75̊C for 30s. A melting curve will follow 
amplification (95̊C for 30s, 25̊C for 60s, 50̊C for 15s and final ramp rate (0.3%-1%) to 95̊C for 15s. 
Each reaction will be done with 40 ng DNA, 50nM forward primer, 500nM reverse primer, and Light 
scanner HRM LC green Master Mix (Biofire Diagnostics, Salt Lake City, Utah). 
 
10.2.2 
HSD3B1 Genotyping by Melting Curve Assay 
Genomic DNA will be prepared from peripheral blood using DNeasy Blood and Tissue Kit (QIAGEN, 
Germantown, MD). PCR products of the promoter region, all exons, exon-intron junctions and the 

CASE 5815 
 
 
 
Page 42  
 
Version date: July 30, 2019 
30-UTR will be sequenced to identify mutations in HSD3B1. To sequence the 30 flanking region of 
HSD3B1, primer set (Forward: 50-ATGTGGAGGGAGGTGTGAGT-30 and Reverse: 50-
ACGGAGATGGGTCTCTTCCA-30 ) will be used with an annealing temperature of 62_C. Genotyping 
PCR reaction (50 ml) will be done with 30-100 ng genomic DNA, 1 x PCR buffer with 0.2 mM dNTP, 
0.2 mM of each primer, and 0.5 ml Phusion High-Fidelity DNA Polymerase (New England BioLabs 
Inc, Ipswich, MA).  1 mL purple top tube will be used for genotyping purposes at indicated time 
points.  
10.3 Immunohistochemical Staining Of Cellular And Molecular Markers In Prostate Tumor Tissue 
IHC for PSA will be performed as routinely done by Dr. Cristina Magi-Galluzzi in the pathology 
department at the Cleveland Clinic. 
10.4 Steroid Extraction and Measurements 
Prostate tissue (20mg) will be homogenized using a Minilyse bead homogenizer (Bergin Corp, Rockville, 
MD). Steroids and internal standard will be extracted using methyl tart Butyl-ether (Sigma-Aldrich, St. 
Louis, MO). Steroids will be derivative using a Girard T reagent (Sigma-Aldrich, St. Louis, MO) as 
previously described (22). Steroid concentrations will be assessed through stable isotope ratios and 
quantitated using developed methodology on a liquid chromatography mass spectrometer.  1 10mL red 
top tube will be used for serum steroid studies at indicated time points.   
10.5 mRNA Expression  
Prostate tissue (<20 mg) will be homogenized and RNA will be extracted using a Gene lute 
Mammalian Total RNA Miniprep Kit ( Sigma Aldrich, St. Louis, MO). Extracted RNA will be 
synthesized into cDNA using an iScript cDNA Synthesis Kit (Bio-Rad, Hercules, CA). Expression for 
PSA, TMPRSS2, FKBP5, EZH2, H3K27, and UBE2C will be assessed by quantitative real time PCR on 
an ABI 7500 Real Time PCR System (Applied Biosystem, Carlsbad, CA). Each reaction (20µL) will 
consist of 100-500 ng of synthesized cDNA, 500 nM each forward and reverse primer set, and 10 
µL of iTaq Universal SYBR Green Supermix ( Bio-Rad, Hercules, CA). The qPCR protocol consists of 
an initial denaturation at 95̊C for 2m followed by 40 cycles of 95̊C for 3s and 60̊C for 35s, with a 
final hold at 4̊C. AR-Responsive gene expression will be normalized to housekeeping gene RPLPO. 
The rationale behind these exploratory analyses derives from existing data demonstrating that 
alterations of the androgen-regulated TMPRSS2 and ETS transcription factor genes in prostate 
cancer tissue leads to worse outcome. Similarly, FKBP5, EZH2, H3K27, and UBE2C are considered 
potential prognostic putative cancer stem cell markers that have been associated with tumor 
aggressiveness and might be altered by the use of Apalutamide and leuprolide therapy

14 Biostatistical Considerations 
All subjects will be receiving Apalutamide starting day (-28) ± 3 days from the scheduled RP date and will 
be genotyped for HSD3B1 before enrollment in the study as a part of the screening. We expect a higher 
concentration of DHT in patients with homozygous HSD3B1(1245C) genotype as a result of flux to DHT 
due to 3βHSD1 abundance.  
14.1  Sample Size and Accrual 
In a recent report by Chang et al24 the prevalence of the homozygous HSD3B1(1245C) genotype was 10% 
in 40 CRPC patients. The prevalence however is to some extent race-dependent.25  
The prevalence of the wild type and heterozygous genotypes were approximately 2:1, and therefore the 
homozygous variant genotype is “rate-limiting” for accrual. The target enrollment is 12 patients who 
have the homozygous HSD3B1(1245C) genotype, 15 patients who are heterozygous, and 30 wild-type 
patients. Because of the low prevalence of homozygous  HSD3B1 (1245C), enrollment in each cohort will 
proceed until its target is reached. A subject who e i t h e r prematurely discontinues from the 
study before completing 28 days of the treatment,  prior to surgery, or for whom we are 
unable to obtain a tissue sample from,  may be replaced in order to achieve target enrollment in 
each cohort.  All safety and efficacy data from all accrued patients independent of the availability of 
post-treatment tumor material will be collected and analyzed. 
Overall, based on the prevalence of the homozygous variant genotype, we predict that we may need to 
screen up to 120 patients to reach our accrual objective. Due to logistical restrictions, an accrual goal of 
80 male patients may be needed in order to capture all objectives for a sample size of 57 patients. 
Accrual is expected to be approximately 2 years in the three cohorts.  
With 57 patients there will be statistical power >80% to detect a 4-fold trend in the primary endpoint, 
DHT concentrations in the resected prostate tissue, as well as similar trends in other androgens and 
molecular markers. The calculation is based on a 2-sided test with 5% type I error; a codominance model 
where there is a 4-fold difference in hormone concentration between the wild-type and homozygous 
variant genotypes and a concentration approximately mid-way between the two for the heterozygous 
genotype; and that variability in this concentration could be as much as 125% of the mean hormone 
tissue concentration for each genotype. Note that 125% of the mean is a conservative estimate of 
variability. If it turns out in fact to be lower – e.g. similar to the 75% seen in a recent study in which 
patients were treated with 6 months leuprolide prior to RP35 , there will be >95% power to detect a 4-
fold range, >90% to detect a 3-fold range, and 75% to detect a 2-fold range.   
14.2   Data Analysis  
Hormone concentrations and tissue PSA, TMPRSS2, FKBP5, EZH2, H3K27, and UBE2C measured by qPCR 
will be summarized as means and standard errors, possibly after data transformation. Differences 
between genotypes within and between tissue types will be analyzed using linear or non-linear models.

Version date: July 30, 2019 
Pearson or Spearman rank correlations will be used to assess associations between the concentrations 
of the different hormones and molecular markers. All tests of statistical significance will be two-sided.
