Synopsis 
Protocol Title: A Phase 3 Open-Label Extension Study to Evaluate the Long-Term Safety and 
Efficacy of Vibegron in Men with Overactive Bladder (OAB) Symptoms on Pharmacological 
Therapy for Benign Prostatic Hyperplasia (BPH) 
Protocol Number: URO-901-3006 
Brief Title: Extension Study of Vibegron in Men with OAB Symptoms With BPH 
Study Rationale: Beta-3 adrenergic receptor (β3-AR) agonists have shown efficacy (with 
improved safety relative to anticholinergics) in treating persistent OAB symptoms in men on 
BPH therapies. This subset of the broader OAB population setting has unique safety needs (eg, 
possibility of urinary retention) that have not been fully evaluated in previous clinical programs 
of OAB treatments. Study URO-901-3006 is designed to evaluate long-term safety and efficacy 
of vibegron (75 mg once daily [QD] administered for 28 weeks) in men with symptoms of OAB 
while receiving pharmacological therapy for BPH who have received 24 weeks of study drug in 
double-blind, placebo-controlled, Phase 3 Study URO-901-3005.  
Objectives: The primary study objective is to assess the long-term safety of vibegron when 
dosed for up to 52 weeks in men with OAB symptoms on pharmacological therapy for BPH who 
previously completed treatment in Study URO-901-3005. The primary clinical hypothesis is that 
vibegron + BPH pharmacological therapy for BPH treatment is safe for long-term use in men 
with OAB symptoms and BPH. 
The secondary study objective is to assess the long-term efficacy of vibegron when dosed for up 
to 52 weeks in men with OAB symptoms on pharmacological therapy for BPH who previously 
completed treatment in Study URO-901-3005. 
Endpoints:  
Note: With respect to study endpoints, “per day” refers to a “Diary Day”, which is defined as the 
time between when the subject gets up for the day each morning and the time the subject gets up 
for the day the next morning as recorded in the subject bladder diary (approximately a 24-hour 
period). 
Safety assessments will include treatment emergent AEs, clinical laboratory tests, physical 
examinations, vital signs, PVR volume, and Total IPSS.

Efficacy endpoints include the following: 
• Change from baseline (CFB) at Week 52 in the average number of micturition episodes 
per day 
• CFB at Week 52 in the average number of urgency episodes (urgency: need to urinate 
immediately) per day 
• CFB at Week 52 in the average the number of nocturia episodes per night  
• CFB at Week 52 in the average number of urge urinary incontinence episodes per day in 
subjects with incontinence at baseline in Study URO-901-3005  
• CFB at Week 52 in the average of International Prostate Symptom Score (IPSS) 1-week 
recall) Storage score (1-week recall) 
• CFB at Week 52 in the average volume voided per micturition 
See Section 3 (Objective and Endpoints) for the other/exploratory endpoints, including quality-
of-life endpoints. 
Statistical Methods: 
Safety analyses will be based on all subjects who receive vibegron (through Week 52 of this 
extension study). Only one treatment group (vibegron) will be reported for safety data. Baseline 
will be the baseline for Study URO-901-3005. Descriptive statistics will be used to summarize 
safety endpoints.  
The efficacy analyses will be for descriptive purposes only and will be conducted using the FAS-
Extension population, which is a subset of the Study URO-901-3005 treated population which 
have completed the 24-week treatment period in Study URO-901-3005 and enrolled into this 
extension study.   
The efficacy endpoints of change from baseline in average number of micturitions, average 
number of urgency episodes, average number of nocturia episodes, average number of urge 
urinary incontinence (UUI) episodes, average of IPSS storage score, and average volume voided 
per micturition will be analyzed separately using a mixed model for repeated measure (MMRM) 
with restricted maximum likelihood estimation. The analysis model for each efficacy endpoint 
will include terms or visit, baseline, baseline stratification factors (those found to be significant 
in Study URO-901-3005). An unstructured covariance matrix will be used to model the 
correlation among repeated measurements. The Kenward-Roger adjustment will be used with 
restricted (or residual) maximum likelihood (REML) to make statistical inference. The adjusted 
means for vibegron and visit will be estimated along with the 95% CI. Only the week-52 subjects 
(those on active treatment in Study URO-901-3005 and in Study URO-901-3006) will be 
included in the model. 
Descriptive statistics will be used to summarize all efficacy endpoints. Summaries of efficacy 
endpoint will be presented by two treatment groups: vibegron for 52 weeks and vibegron for 
28 weeks as determined by the randomized treatment in Study URO-901-3005.

Overall Study Design: This is an international Phase 3, open-label 28-week extension study to 
evaluate the safety and efficacy of vibegron 75 mg in men with symptoms of OAB on stable 
doses of pharmacological therapy for BPH. This study is an extension for subjects who have 
completed the Phase 3, double-blind, randomized, 24-week Study URO-901-3005.  
Approximately 300 men with symptoms of OAB on stable doses of pharmacological therapy for 
BPH who completed 24 weeks in Study URO-901-3005 and continue to qualify for this study 
may be permitted to enroll in this extension study, from approximately 60 study sites. 
During this extension study, subjects who had been randomized in Study URO-901-3005 to 
receive vibegron 75 mg will continue their same treatment once daily for an additional 28 weeks, 
and subjects who had been randomized in Study URO-901-3005 to the placebo group will 
receive study treatment of vibegron 75 mg once daily for 28 weeks during the extension. Thus, 
through participation in both the URO-901-3005 and URO-901-3006 (extension) studies, 
subjects originally randomized to vibegron will receive 52 weeks total of vibegron treatment, and 
subjects originally randomized to placebo will receive 28 weeks total of vibegron treatment. 
Study visits will be named to reflect continuation from Study URO-901-3005, with the first 
study visit of this extension study occurring at Week 24. Following enrollment in this extension 
study, subjects will return to the clinic for visits at Week 28, Week 36, and Week 52 (all relative 
to Day 1 of Study URO-901-3005). A telephone contact will occur at Week 44 to review 
AEs/serious AEs (SAEs) and concomitant medications. 
This study consists of a 28-week open-label Treatment Period. Unscheduled Visit(s) may be 
arranged as needed. 
Number of Subjects: Up to 300 subjects who complete Study URO-901-3005 may be offered 
the opportunity to roll over into this study.  
Number of Sites: Approximately 60 sites in North America and Europe. 
Study Drug Groups and Study Duration: 75 mg vibegron, QD, administered orally. Study 
drug will be administered in an open-label (not blinded) manner for 28 weeks on Study URO-
901-3006. Note: upon entering this extension study, all subjects will have already received 
2 weeks of treatment with placebo plus an additional 24 weeks of blinded treatment with either 
vibegron or placebo in Study URO-901-3005. No dosage adjustments will be allowed. 
Subjects will continue on the same alpha-blockers (eg, tamsulosin, doxazosin, and alfuzosin) 
with or without 5α-reductase inhibitors (5-ARIs) use (eg, finasteride, dutasteride, and alfatradiol) 
in Study URO-901-3006 as administered in Study URO-901-3005. 
Data Safety Monitoring Board (DSMB): A DSMB will be retained to assess, on an ongoing 
basis, all safety aspects of this study. This will be an external independent DSMB that monitors 
the safety for both Study URO-901-3005 and Study URO-901-3006. The detailed activities 
including meeting plans will be described and documented in the DSMB Charter. A separate 
statistical analysis plan will be prepared for the DSMB.

Introduction 
2.1. 
Study Rationale 
Men with overactive bladder (OAB) symptoms associated with benign prostatic hypertrophy 
(BPH) represent an OAB subpopulation that has not been extensively studied. Often in these 
patients, OAB symptoms remain inadequately addressed despite treatment for their BPH 
(ie, alpha-blocker with or without 5-ARI). For reasons described below, this population warrants 
specific clinical studies to adequately evaluate and address their unique medical needs. Study 
URO-901-3006 is an extension study to Phase 3 Study URO-901-3005 designed to evaluate 
safety, tolerability, and efficacy of vibegron (75 mg once daily [QD]) for up to 52 weeks in men 
with OAB symptoms on pharmacological therapy for BPH. 
2.2. 
Background 
2.3. 
Overactive Bladder in Men with Benign Prostatic Hyperplasia 
OAB is highly prevalent and affects approximately 16% of the population in the United States 
and Europe. Prevalence increases with age, affecting approximately one third of people 75 years 
and older [Stewart, 2003; Milsom, 2001]. Despite similar prevalence between the sexes and 
growing clinical trial evidence that men benefit from pharmacotherapy, men are less likely to use 
treatment for OAB [Goldman, 2016].  
The International Continence Society (ICS) defines OAB as urgency, with or without urge 
incontinence, usually associated with frequency and nocturia [Abrams, 2002]. Urgency is 
defined as a sudden compelling desire to void which is difficult to defer and, from the medical 
definition perspective, it is a necessary symptom for OAB. Urgency incontinence is the 
involuntary loss of urine accompanied by urgency (referred to as OAB Wet) and is present in 
approximately one-third of patients with OAB [Stewart, 2003; Milsom, 2001]. In the absence of 
incontinence, OAB is referred to as OAB Dry. Urgency incontinence is distinguished from stress 
urinary incontinence, which is the involuntary loss of urine on effort or physical exertion (eg, 
sporting activities), or upon sneezing or coughing. When both components are present, the 
classification is mixed urinary incontinence, with either urgency or stress specified as the 
predominant component.  
Although the overall prevalence of OAB in men and women is similar, there are major 
differences in predominating symptoms. Men are more likely to experience urgency, frequency, 
and nocturia accompanied by lower urinary tract symptoms (LUTS) associated with voiding 
dysfunction, whereas women are twice as likely to experience incontinence [Tubaro, 2017]. 
Since most men with OAB symptoms do not have urinary incontinence, the micturition 
frequency and the urgency become the predominant symptoms that characterize the disease for

the men with OAB on pharmacological therapy for BPH [Helfand, 2012]. Among men, urinary 
incontinence significantly increases after the age of 65 years.  
Historically in men with BPH, LUTS have been presumed to result from bladder outlet 
obstruction secondary to prostate enlargement. However, men may have OAB symptoms in the 
absence of, or in conjunction with, voiding symptoms associated with BPH or urodynamic 
evidence of bladder outlet obstruction [Nakagawa, 2008; Hyman, 2001]. BPH can be associated 
with debilitating LUTS, categorized by storage symptoms (eg, urinary frequency, urgency, and 
nocturia) and voiding dysfunction (eg, decreased and intermittent force of stream and the 
sensation of incomplete bladder emptying).  
2.3.1. 
Vibegron 
Initial pharmacologic therapy for OAB symptoms in men with BPH traditionally has been 
directed at minimizing the obstruction and has included α1-adrenergic receptor antagonists to 
relax the muscles of the prostate and bladder neck or 5-ARIs to reduce prostate growth 
[American Urological Association, 2010]. While patients may see some improvement in OAB 
symptoms with these BPH therapies (eg, improvement in urinary flow), symptom control for 
OAB symptoms is incomplete, for many, and urinary urgency, incontinence, frequency, or 
nocturia persists [Abrams, 2002]. To address persistent OAB symptoms in men with BPH, 
combinations of BPH therapies with OAB medications, such as anticholinergics, have shown 
promise [Chapple, 2009; Oelke, 2013]. However, the clinical use of anticholinergics is limited 
by mechanism-based side effects including dry mouth and constipation [MacDiarmid, 2008] and 
the potential for CNS adverse effects [Gray, 2015; Risacher, 2016]. Further, 
contraindications/precautions exist due to the possibility of urinary retention and bladder outflow 
obstruction [Detrol prescribing information, 2016].  
ß3-adrenoceptor (β3-AR) agonists for OAB (eg, mirabegron) have demonstrated efficacy in 
treating persistent OAB symptoms in men on BPH therapies [Ichihara, 2014] with a more 
favorable safety profile relative to the anticholinergics. In fact, experts have recommended that 
these agents be specifically studied in this patient population [Maman, 2014; Chapple, 2009; 
Van Kerrebroeck, 2001; Chapple, 2017].  
Vibegron is a potent and highly selective β3-AR agonist demonstrating > 9000-fold selectivity 
for activation of β3-AR over β2-AR and β1-AR in cell based in vitro assays. β-adrenergic 
receptors are prototypic G-protein coupled receptors expressed on the surface of cells, and 
mediate intracellular signaling via coupling to Gs and increasing levels of intracellular cyclic 
adenosine monophosphate (cAMP). β3-ARs are widely distributed in humans and are the most 
prevalent β-AR subtype expressed on human detrusor smooth muscle [Takeda, 2000]. In isolated 
human bladder smooth muscle, activation of β3-AR using subtype-selective agonists results in 
smooth muscle relaxation suggesting a role for β3-AR agonists during the filling phase of the 
micturition cycle [Yamaguchi, 2002; Biers, 2006]. In rodent models of bladder overactivity, β3-
AR agonists relax bladder smooth muscle and suppress detrusor smooth muscle instability and 
hyperreflexia [Takeda, 2000; Woods, 2001; Takeda, 2002; Kaidoh, 2002]. In rhesus monkeys,

dose dependent increases in bladder capacity and decreases in micturition pressure were 
observed with vibegron. Bladder capacity was further increased by vibegron in combination with 
tolterodine or darifenacin [Di Salvo, 2017]. These results have supported a large and 
comprehensive clinical development program for vibegron in the general OAB population, 
including both male and female subjects. 
More than 2300 subjects (including 1840 with OAB and 460 healthy volunteers) have received 
vibegron in Phase 1, 2, and 3 clinical studies. Assessment of safety laboratory parameters and 
mean vital sign values over time, including heart rate and blood pressure, showed no clinically 
meaningful differences for any active treatment group relative to placebo or anti-muscarinic 
comparators. A large, multicenter Phase 3 study of vibegron for the treatment of OAB in women 
and men is ongoing. Discontinuation rates due to adverse events (AEs) were low (< 5%) in all 
clinical studies conducted to date with vibegron. In a completed Phase 3 study in Japan in more 
than 1200 subjects with symptoms of OAB, there were no notable mean changes in post voided 
residuals observed [Yoshida, 2018]. A more detailed description of vibegron, including 
pharmacology, efficacy, and safety data in overactive bladder, is provided in the Investigator’s 
Brochure.  
2.4. 
Benefit/Risk Assessment 
2.4.1. 
Potential Benefits 
Vibegron’s mechanism of action has the potential to demonstrate significant therapeutic benefit 
in the treatment of OAB symptoms in men with BPH on pharmacological therapy for their BPH 
symptoms. 
2.4.2. 
Potential Risks 
The initial clinical program for vibegron in the treatment of OAB includes subjects of both sexes. 
It is estimated that the ongoing Phase 3 program in OAB (RVT-901-3003 and RVT-901-3004) 
will include approximately 15% males, which will contribute to safety data comprising more 
than 200 men in addition to those enrolled in the URO-901-3005 and URO-901-3006 studies. 
Based on aggregate preclinical, clinical pharmacology, and Phase 2 and 3 studies, AEs of special 
interest (AESIs) predefined for specific evaluations in vibegron clinical studies are as follows:  
• Potential major cardiovascular events 
• Hypertension 
• AEs suggestive of orthostatic hypotension as confirmed by orthostatic vital signs 
• AEs suggestive of cystitis or urinary tract infection 
• Elevated aspartate transaminase (AST) or alanine transaminase (ALT) laboratory value 
requiring that the study drug be temporarily withheld or permanently discontinued 
• Neoplasm

In addition, the risk for increases in post void residual urine volume and urinary volume will be 
closely monitored for post-void retention during the study. Study URO-901-3005 enrollment 
criteria will exclude men with PVR volume ≥ 100 mL at screening and at baseline and those with 
maximum urinary flow (Qmax) less than 5 mL/second. Post-void residual urine volume will be 
assessed throughout the study, and subjects with a single PVR volume of ≥ 300 mL or an AE of 
urinary retention will be withdrawn.  
Prespecified definitions of urinary retention and other AESIs are provided in the Adverse Event 
of Special Interest section (Section 8.4.6). More detailed information about the known and 
expected benefits and risks from the study and reasonably expected AEs of vibegron may be 
found in the Investigator’s Brochure.

Study Design 
4.1. 
Overall Design 
This study is a Phase 3, open-label, 28-week extension study to evaluate the safety and efficacy 
of vibegron 75 mg in men with symptoms of overactive bladder (OAB) on stable doses of 
pharmacological therapy for BPH. This study is an extension for subjects who have completed 
the Phase 3, double-blind, randomized, 24-week Study URO-901-3005.  
Subjects who complete Study URO-901-3005 may be given the opportunity to enroll in this 
extension study. It is anticipated that approximately 300 men who completed Study URO-
9013005 and continue to qualify for this study may be permitted to enroll in this extension study. 
During this extension study, subjects who had been randomized to receive vibegron 75 mg in 
Study URO-901-3005 will continue their same treatment once daily for an additional 28 weeks; 
subjects who had been randomized to receive placebo in Study URO-901-3005 will receive 
study treatment of vibegron 75 mg once daily for 28 weeks during this extension study. Thus, 
through participation in both the URO-901-3005 and URO-901-3006 (extension) studies, 
subjects originally randomized to vibegron will receive 52 weeks total of vibegron treatment, and 
subjects originally randomized to placebo will receive 28 weeks total of vibegron treatment. 
Study visits will be named to reflect continuation from the URO-901-3005 study, with the first 
study visit of this extension study occurring at Week 24 (Visit 11). Following enrollment in this 
extension study, subjects will return to the clinic for visits at Week 28, Week 36, and Week 52 
(all relative to Day 1 of URO-901-3005). A telephone contact will occur at Week 44 to review 
AEs/SAEs and concomitant medications. 
This study consists of a 28-week open-label Treatment Period. Unscheduled Visit(s) may be 
arranged as needed.  
4.1.1. 
Clinical Hypotheses 
The primary clinical hypothesis is that is that the vibegron + pharmacological therapy for BPH 
treatment is safe in men with OAB symptoms and BPH. 
4.2. 
Scientific Rationale for Study Design 
The clinical use of anticholinergics is limited by adverse effects and, notably, contraindications 
and precautions unique to men with OAB symptoms receiving treatment for BPH due to the 
possibility of urinary retention and bladder outflow obstruction. ß3-adrenoceptor agonists have 
shown efficacy (with improved safety relative to anticholinergics) in treating persistent OAB 
symptoms in men on BPH therapies [Ichihara, 2014]; however, no therapeutic agents are labeled 
specifically for this population, and clinical study data have been limited. In addition, this 
population has a distinct symptom profile and relevant efficacy needs (eg, nocturia) that warrant 
further study.

Discontinuation of Study Drug and Subject Discontinuation or 
Withdrawal 
A premature discontinuation will occur if a subject who signs the informed consent form (ICF) 
and is dosed ceases participation in the study, regardless of circumstances, before the completion 
of the protocol-defined study procedures. 
7.1. 
Discontinuation of Study Drug 
Subjects who discontinue study drug will complete the Week 52/Early Withdrawal assessments 
specified in the Schedule of Assessments (Section 1.3).  
Reasons for discontinuation from the study drug include the following: 
• Any AE of urinary retention  
• Any occurrence of PVR volume ≥ 300 mL 
Discontinuation of study drug for abnormal liver function should be considered by the 
investigator when a subject meets all of the conditions outlined in Section 8.4.6.2 for Hy’s law or 
if the investigator believes that it is in best interest of the subject (reason for discontinuation will 
be AE).  
7.2. 
Subject Discontinuation/Withdrawal from the Study 
• A subject who discontinues study drug will also be withdrawn from the study. 
• A subject may choose to withdraw from the study at any time at his own request, or may be 
withdrawn at any time at the discretion of the investigator for safety, behavioral, compliance, 
or administrative reasons. 
• If a subject withdraws consent for disclosure of future information, the Sponsor or designee 
may retain and continue to use any data collected before such a withdrawal of consent. 
• If a subject withdraws from the study, he may request destruction of any blood or urine 
samples taken and not tested, and the investigator must document this in the site study 
records. 
• Subjects who withdraw from the study will not be replaced.  
The Week 52/Early Withdrawal assessments will be completed when a subject withdraws or is 
withdrawn from the study, if possible (see Schedule of Assessments in Section 1.3).

• Protocol deviation 
• Death 
• Other 
7.3. 
Lost to Follow Up 
Should a subject fail to attend a required study visit, the site should attempt to contact the subject 
and re-schedule the missed visit as soon as possible. The site should also counsel the subject on 
the importance of maintaining the assigned visit schedule and ascertain whether or not the 
subject wishes to and/or should continue in the study based on previous non-compliance. In 
cases where the subject does not return for the rescheduled visit or cannot be reached to 
reschedule the missed visit, the site should make every effort to regain contact with the subject 
so that they can appropriately be withdrawn from the study with a primary reason of “Lost to 
Follow-up”. Including at least three documented attempts to contact the subject (ie, phone, email, 
or certified letter). Efforts to establish the possible reason for discontinuation should be 
documented. 
7.4. 
Early Study Termination 
The Sponsor reserves the right to terminate the study for any reason. The study may be 
terminated early if the extent (incidence and/or severity) of emerging effects/clinical endpoints is 
such that the risk/benefit ratio to the study population as a whole is unacceptable. In addition, 
further recruitment in the study overall or at a particular study site may be stopped due to 
insufficient compliance with the protocol, Good Clinical Practice and/or other applicable 
regulatory requirements, procedure-related problems or the number of discontinuations for 
administrative reasons is too high.

personnel should note the following: 
• Protocol waivers or exemptions are not allowed. Any notable protocol deviations should 
be noted and raised to the Sponsor’s or designee’s attention. 
• Immediate safety concerns should be discussed with the Sponsor’s designated Medical 
Monitor immediately upon occurrence or awareness to determine if the subject should 
continue or discontinue study drug. 
• Adherence to the study design requirements, including those specified in the Schedule of 
Assessments, is essential and required for study conduct. 
• Note that patient-reported outcome (PRO) assessments will be completed prior to vital 
signs, and vital signs will be taken prior to blood draws.  
• Procedures conducted as part of the subject’s routine clinical management (eg, blood 
count) and obtained before signing of the ICF may be utilized for the purposes of 
confirming eligibility (in addition to the most recent available assessments from Study 
URO-901-3005).

As this is an extension study that includes subjects from the ongoing parent study, URO-
9013005, assessments performed at the end of the parent study will not be repeated on study 
entry into Study URO-901-3006. Specifically, vital sign, physical examination, laboratory, 
bladder diary, PVR urine, and PRO assessments performed at the Week 24 Visit of Study URO-
901-3005 will be considered the initial study assessments at entry into extension Study URO-
901-3006. 
In addition, medical history and demographic information from entry into Study URO-901-3005 
will be used as relevant to provide information for Study URO-901-3006.  
8.1.1. 
Informed Consent 
Documented consent (for Study URO-901-3006) must be obtained from each potential subject 
prior to the first dose of open-label study drug (vibegron) on Study URO-901-3006 according to 
the process described in Section 10.1.3.

Assignment of Subject Number 
All subjects who enroll in Study URO-901-3006 will retain the same study number that they 
were assigned in Study URO-901-3005.  
The investigator will maintain a log to confirm eligibility or record reasons for ineligibility, as 
applicable. Inclusion and exclusion criteria (Section 5.1 and Section 5.2) will be reviewed by the 
investigator or qualified designee at Week 24 of Study URO-901-3005). If needed, the Week 24 
laboratory results from Study URO-901-3005 may be used to confirm eligibility. 
8.1.3. 
Concomitant Medications 
Ongoing medications will be recorded beginning at the signing of the ICF and continuing until 
the last dose of study drug. 
8.2. 
Efficacy Assessments 
Efficacy assessments will be collected as outlined in the Schedule of Assessments (Section 1.3) 
in the form of 3-day Bladder Diary. Information collected in the diaries will be used for 
assessment of the efficacy endpoints related to the number of micturition, urgency, nocturia, and 
incontinence episodes per day as well as the volume voided per micturition. In addition, subjects 
will complete IPSS assessments and
Patient Global Impression (PGI), and
scores to assess quality of life parameters. 
Subjects will complete questionnaires at the site at the start of each required study visit (before 
vital signs and blood draws). The PRO questionnaires are provided in Section 10.8. Additional 
information on the Bladder Diary and questionnaires is provided below. 
8.2.1. 
Bladder Diaries 
Bladder Diary is used by subjects to record the frequency of daily OAB symptoms including all 
micturitions, urgency, incontinence, nocturia, one 24-hr volume voided of urine (used to derive 
the volume per micturition), and main reason for incontinence, and volume voided per 
micturition (over one 24-hour period) by selecting the respective box for each symptom 
occurring during the course of a given day and night. 
The Bladder Diary should be completed by the subject on 3 consecutive days within the 7 days 
prior to Visit 12 (Week 28), Visit 13 (Week 36) and Visit 14 (Week 52). A “Diary Day” is 
defined as the time between when the subject gets up for the day each morning (ie, the time the 
subject got up for the day yesterday to the time the subject got up for the day today; 
approximately a 24-hour period). Urine volume may be collected during any one (1) of the 3 
Diary Days prior to the visit.

At all study visits, the site staff should inquire whether the subject had any difficulties with the 
diary and address any questions subjects may have. Instructions for proper completion of the 
diary should be re-reviewed. Subjects will be trained to enter data immediately following each 
event (in real time) and to input data from any “missed” events as soon as they are able. They 
will review and confirm that data from all events occurring within the preceding Diary Day 
(approximately 24 hours) have been entered at a consistent time each morning (eg, upon getting 
up for the day). 
8.2.2. 
Patient-Reported Outcomes 
Subjects will complete questionnaires at the site at the start of each required study visit (before 
vital signs and blood draws) to assess subject-perceived symptom relief, symptom bother, and 
health-related quality of life. These include the following questionnaires: 
• The IPSS includes 8 questions (7 concerning urinary symptoms and 1 concerning quality 
of life), each with answers based on a 6-point scale indicating increasing severity. The 
urinary symptom responses are assigned points from 0 to 5.  The Total IPSS Score can 
therefore range from 0 to 35 (asymptomatic to very symptomatic). The quality of life 
responses are assigned points from 0 to 6. A sample of the IPSS is provided in 
Section 10.8.1. 
• 
 (1-week recall) is a multi-item questionnaire that was developed to assess 
symptom bother and the impact of 
 
The instrument was developed and validated in both continent and incontinent OAB 
patients, including both men and women. A sample of the
 scales is provided 
in Section 10.8.2. 
• The EQ-5D health questionnaire is a standardized instrument for use as a measure of 
health outcome [Rabin 2014]. It is applicable to a wide range of health conditions and 
treatments; it provides a simple descriptive profile and a single index value for health 
status. A sample of the EQ-5D health questionnaire is provided in Section 10.8.3. 
• Global Impression Items include 
 A sample of the PGI scale is provided in Section 10.8.4. 
• 
The investigator should not provide any additional information to subjects prior to completing 
the questionnaires that might influence responses.

Safety Assessments 
Planned timepoints for all safety assessments, including assessments for PVR, are provided in 
the Schedule of Assessments (Section 1.3). Immediate safety concerns should be discussed with 
the Sponsor’s designated Medical Monitor immediately upon occurrence or awareness to 
determine if the subject should continue or discontinue study drug. 
8.3.1. 
Vital Signs 
Vital signs, including blood pressure, heart rate (by pulse), body temperature, and weight, will be 
assessed at the timepoints specified in the Schedule of Activities and Section 10.7 as follows: 
• Blood pressure and pulse will be measured after the subject has been resting in a seated 
position for 5 minutes, after PRO assessments and before blood draws.  
• Blood pressure measurements will be taken on the same arm and by the same site staff 
throughout the study, if possible.  
• Sitting systolic and diastolic blood pressures will be determined by averaging 3 replicate 
measurements obtained approximately 1 to 2 minutes apart. The average of the 3 
measurements will be used for eligibility and safety assessments.  
• The same method for assessing temperature should be used at all visits for a particular 
subject. 
• Body weight will be measured with subjects in street clothing with jacket/coat and shoes 
removed, using the same scale throughout the study, if possible. 
8.3.2. 
Physical Examinations 
Brief physical examinations will include examination of the heart, lungs, abdomen, and visual 
pelvic examination. In addition, any organ system in which a previous abnormality was noted at 
Baseline or a subject has a complaint or AE will be examined.  
8.3.3. 
Post-Void Residual Volume 
The volume of urine that remains in the bladder after voiding (PVR) is an objective measurement 
that may serve as a proxy for impaired ability to void. The physician should assess subjects with 
an increase in PVR volume to determine whether an AE should be reported. (Refer to 
Section 8.4.6 for additional information on reporting AEs of urinary retention associated with 
increased PVR.) 
The PVR assessment will be performed via ultrasound at the visits indicated in the Schedule of 
Assessments (Section 1.3). All efforts will be made to ensure the same device and operator are 
used for all PVR volume measurements for individual subjects.

Clinical Safety Laboratory Assessments 
All protocol-required laboratory assessments must be conducted in accordance with the 
laboratory manual and the Schedule of Assessments. See Section 10.2 for the list of clinical 
laboratory tests to be performed and the Schedule of Assessments for the timing and frequency. 
Repeat or unscheduled samples may be taken for safety reasons or for technical issues with the 
samples. 
The clinical significance of test results will be evaluated as follows: 
• At Week 24 of Study URO-901-3005, the investigator or physician subinvestigator will 
assess the clinical significance of any values outside the reference ranges provided by the 
laboratory, and subjects with abnormalities judged to be clinically significant will be 
excluded from the study. 
• The investigator or physician subinvestigator must review the laboratory report, document 
this review, and record any clinically relevant changes occurring during the study in the AE 
section of the eCRF. The laboratory reports must be filed with the source documents. 
Laboratory abnormalities associated with the underlying disease are not considered clinically 
significant unless judged by the investigator to have worsened or be more severe than 
expected for the subject’s condition. 
• All laboratory tests with values considered clinically significant during participation in the 
study or within 21 days after the last dose of study drug should be repeated until the values 
return to normal or baseline or are no longer considered clinically significant by the 
investigator or the Sponsor’s designated Medical Monitor.  
- If such values do not return to normal/baseline within a period of time judged reasonable 
by the investigator, the etiology should be identified and the Sponsor’s designated 
Medical Monitor notified. 
- If laboratory values from nonprotocol specified laboratory assessments performed at the 
institution’s local laboratory require a change in subject management or are considered 
clinically significant by the investigator (eg, SAE or AE or dose modification), then the 
results must be recorded in the eCRF. 
8.4. 
Adverse Events and Serious Adverse Events 
The definitions of an AE or SAE can be found in Section 10.3. 
AEs will be reported by the subject (or, when appropriate, by a caregiver, surrogate, or the 
subject’s legally authorized representative). 
The investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet the definition of an AE or SAE and remain responsible for following 
up AEs that are serious, considered related to the study drug or study procedures, or that caused 
the subject to discontinue the study drug or the study (see Section 7).

8.4.1. 
Time Period and Frequency for Collecting Adverse Event and Serious Adverse 
Event Information 
All AEs and SAEs will be collected from the signing of the informed consent form through the 
end of study.  In addition, any AEs and SAEs reported within 21 days after the last dose of study 
drug (5 half-lives of vibegron [half-life approximately 80 hours]) will also be collected. AEs will 
be collected at the timepoints specified in the Schedule of Assessments (Section 1.3), and as 
observed or reported spontaneously by study subjects. 
Medical occurrences that begin before the start of study drug, but after obtaining informed 
consent will be recorded in the AE section of the eCRF. 
All SAEs (including serious AESIs) will be recorded and reported on the eCRF within 24 hours 
of the study site personnel’s knowledge of the event, as indicated in Section 8.4.4. Marking the 
event as “serious” will automatically send required notifications for Sponsor or designee review. 
The investigator will also submit any updated SAE data within 24 hours of receipt of the 
information. Nonserious AESIs will be reported on the eCRF within 72 hours of the site’s 
knowledge of the information 
Investigators are not obligated to actively seek AE or SAE information after conclusion of the 
study participation. However, if the investigator learns of any SAE, including a death, at any 
time after a subject has been discharged from the study, and he/she considers the event to be 
reasonably related to the study drug or study participation, the investigator must promptly notify 
the Sponsor or designee. 
The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Section 10.3. 
8.4.2. 
Method of Detecting Adverse Events and Serious Adverse Events 
Care will be taken not to introduce bias when detecting AEs and SAEs. Open-ended and 
non-leading verbal questioning of the subject is the preferred method to inquire about AE 
occurrences. 
8.4.3. 
Follow-up of Adverse Events and Serious Adverse Events 
After the initial AE or SAE report, the investigator is required to proactively follow each subject 
at subsequent visits/contacts. All AEs will be followed until approximately 21 days after the last 
dose of study drug. All SAEs will be followed until resolution, stabilization, the event is 
otherwise explained, or the subject is lost to follow-up (as defined in Section 7.3). If a subject 
dies during participation in the study or within 21 days of the last dose of study drug, the 
investigator will provide the Sponsor or designee with a copy of any postmortem findings 
including histopathology.

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by the Sponsor or 
designee to elucidate the nature and/or causality of the AE or SAE as fully as possible. This may 
include additional laboratory tests or investigations, histopathological examinations, or 
consultation with other health care professionals. 
New or updated information will be recorded in the originally completed eCRF. As noted above, 
the investigator will submit any updated SAE data to the Sponsor or designee within 24 hours of 
receipt of the information. 
8.4.4. 
Regulatory Reporting Requirements for Serious Adverse Events 
• Prompt notification of an SAE by the investigator to the Sponsor or designee is essential so 
that legal obligations and ethical responsibilities towards the safety of subjects and the safety 
of a study drug under clinical investigation are met.  
• The Sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study drug under clinical investigation. The Sponsor 
will comply with country-specific regulatory requirements relating to safety reporting to the 
regulatory authority, IRBs/IECs, and investigators.  
• Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSARs) according to local regulatory requirements and Sponsor policy and 
forwarded to investigators as necessary. 
• An investigator who receives an investigator safety report describing an SAE or other 
specific safety information (eg, summary or listing of SAEs) from the Sponsor or designee 
will review and then file it and will notify the IRB/IEC/REB, if appropriate according to 
local requirements. 
8.4.5. 
Disease-Related Events and/or Disease-Related Outcomes Not Qualifying as 
Adverse Events or Serious Adverse Events 
No disease-related events or outcomes are excluded from AE reporting. Any worsening of OAB 
or BPH symptoms or any events of bladder obstruction should be collected as AEs.  
8.4.6. 
Adverse Events of Special Interest 
Selected nonserious and SAEs will be reported as AESIs. AESIs that also meet the definition of 
an SAE must be reported as described in Section 10.3.  
Adverse events of special interest for this study include:  
• Adverse events consistent with urinary retention 
- An AE of urinary retention should only be recorded when a subject has a raised PVR 
that requires intervention with clean intermittent catherization (CIC) or temporary 
placement of a urinary catheter according to the following criteria: 
a) subject has a PVR of ≥ 300 mL (regardless of symptoms), OR 

Urovant Sciences

Protocol URO-901-3006 
 
Version 1.0 
34 
22 May 2019 
b) subject has a PVR ≥ 200 mL and < 300 mL and the subject reports associated 
symptoms, ie, sensation of bladder fullness or inability to void despite persistent 
effort, that in the investigator’s opinion require CIC. 
Note: An AE of residual urine volume should be recorded if, in the investigator’s 
opinion, the raised PVR is clinically significant but does not fulfill the above 
definition for urinary retention. As stated above in Section 7, subjects with a 
single PVR volume of ≥ 300 mL or an AE of urinary retention will be withdrawn 
from the study. 
• Adverse events suggestive of cystitis or urinary tract infection (UTI) 
- An AE of UTI will be recorded if both the following criteria are fulfilled, regardless 
of subject symptoms: 
 a) a positive urine culture result with a bacteriuria count of ≥ 105 CFU/mL 
 b) leukocyturia of ≥ 5/hpf 
If a subject meets the criteria for the definition of a UTI, the investigator will 
record whether the UTI was “symptomatic” or “asymptomatic” on the AE 
eCRF. 
Note: If urinalysis/culture results are reported which, in the opinion of the 
investigator, are considered clinically significant but do not fulfill the above 
definition of a UTI, the findings should be recorded as AEs (eg, bacteriuria, 
leukocyturia). 
• Potential major cardiac and cerebrovascular events, including death (or any event with fatal 
outcome), myocardial infarction, cerebrovascular accident, hospitalization for unstable 
angina or chest pain, hospitalization for heart failure requiring hospitalization, and coronary 
revascularization/angioplasty/stent 
• Hypertension, defined as follows: 
- For subjects with systolic blood pressure < 140 mmHg and diastolic blood pressure 
< 90 mmHg at the Study URO-901-3005 baseline assessment, the average of 3 
systolic blood pressures ≥ 140 mmHg or diastolic blood pressures ≥ 90 mmHg (or 
both) at any 2 consecutive visits after baseline 
- For subjects with systolic blood pressure ≥ 140 mmHg or diastolic blood pressure 
≥ 90 mmHg at Study URO-901-3005 baseline, an increase compared to baseline at 
2 consecutive visits in the average of 3 systolic blood pressures by ≥ 20 mmHg or 3 
diastolic blood pressures by ≥ 10 mmHg 
- Initiation or increase in dose of medication for treatment of hypertension in any 
subject 
• Adverse events consistent with orthostatic hypotension as confirmed by orthostatic vital 
signs

• Elevated serum aspartate aminotransferase (AST) or alanine aminotransferase (ALT) lab 
value requiring that study drug be temporarily withheld or permanently discontinued (see 
Section 8.4.6.1 and 8.4.6.2). To date, no concern regarding drug-induced liver toxicity has 
been identified; however, the Sponsor is monitoring laboratory data for a potential safety 
signal, consistent with Food and Drug Administration guidance [FDA Guidance, 2009]. 
• Neoplasms 
Serious AESIs and elevated liver enzymes or bilirubin requiring withholding of study drug (see 
Section 8.4.6.1) must be reported within 24 hours of the study site personnel’s knowledge of the 
event by marking the appropriate box on the AE eCRF and assigning the most appropriate 
category. Additional information should be provided as directed in the eCRF Completion 
Guidelines. AESIs that also meet the definition of an SAE must be reported as an SAE, as 
described in Section 8.4.4. Nonserious AESIs should be reported within 72 hours of the site 
personnel’s knowledge, using the AE eCRF. 
8.4.6.1. 
Criteria for Temporary Withholding of Study Treatment in Association with 
Liver Test Abnormalities 
Elevated liver enzymes or bilirubin sufficient to require withholding study medication must be 
reported within 24 hours of the study site personnel’s knowledge of the event using AESI 
specific eCRFs/forms/worksheets provided for the study.  
Hepatic enzymes will be monitored in accordance with FDA drug-induced liver injury guidelines 
[FDA, 2009].  
If any of the following liver test abnormalities develop, Study Treatment should be withheld 
immediately with appropriate clinical follow-up (including repeat laboratory tests, until a 
subject’s laboratory profile has returned to normal/baseline status), and the event reported as an 
SAE:  
• ALT or AST > 8 x upper limit of normal (ULN) 
• ALT or AST > 5 x ULN and persists for more than 2 weeks  
• ALT or AST > 3 x ULN and total bilirubin > 2 x ULN or international normalized ratio 
(INR) > 1.5 
• ALT or AST > 3 x ULN with appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash and/or eosinophilia (> 5%)  
Rechallenge may be considered if an alternative cause for the abnormal liver tests (ALT, AST, 
total bilirubin) is discovered and the laboratory abnormalities resolve to normal or baseline 
values. The investigator and Sponsor’s designated Medical Monitor must discuss and agree with 
any decision to rechallenge.  
Rechallenge should not occur when the etiology of the liver test abnormalities is considered 
possibly drug induced.

8.4.6.2. 
Criteria for Permanent Discontinuation of Study Treatment in Association with 
Liver Test Abnormalities 
Study treatment should be discontinued permanently if all of the following 4 criteria are met (ie, 
potential severe drug-induced liver injury/Hy’s law case):  
• Total bilirubin increases to > 2 x ULN or INR > 1.5 and  
• AST or ALT increases to ≥ 3 x ULN and  
• Alkaline phosphatase value does not reach 2 x ULN and  
• No alternative cause explains the combination of the above laboratory abnormalities; 
important alternative causes include, but are not limited to the following:  
- Hepatobiliary tract disease  
- Viral hepatitis (eg, hepatitis A/B/C/D/E, Epstein-Barr virus)  
- Exposure to hepatotoxic agents/drugs or hepatotoxins, including herbal and dietary 
supplements, plants, and mushrooms  
- Alcoholic hepatitis  
- Non-alcoholic steatohepatitis  
- Autoimmune hepatitis  
If an alternative cause for hepatotoxicity is identified, then it should be determined (based on the 
severity of the hepatotoxicity or event) whether study drug should be withheld or permanently 
discontinued as appropriate for the safety of the subject, following consultation with the 
Sponsor’s designated Medical Monitor. 
8.4.7. 
Pregnancy Management and Reporting to the Sponsor 
In the event that a partner of a male study subject becomes pregnant during the study, if the 
subject agrees, the subject’s pregnant partner should be notified of the subject’s study 
participation and be requested to sign a Release of Information form, permitting transfer of 
information regarding the pregnancy and outcome to the Sponsor. If the subject and the subject’s 
partner agree, the investigator should notify the partner’s primary care physician and provide 
details of the subject’s participation in the study. 
Partner pregnancies are to be reported to the Sponsor within 24 hours of awareness by the study 
site personnel, using the pregnancy reporting forms and information for safety event reporting in 
Section 10.3. The expected date of delivery or expected date of the end of the pregnancy, last 
menstruation, estimated conception date, pregnancy result, neonatal data, etc. should be included 
in this information, as available. 
If the subject and partner agree, the investigator will follow the medical status of the mother, the 
pregnancy, as well as the outcome of the infant at birth, and will report the outcome to the 
Sponsor.

Medication Errors 
Medication error refers to any unintended error in the dosing and/or administration of the study 
drug as per instructions in the protocol. Medication errors generally fall into 4 categories as 
follows: 
• Wrong study drug 
• Wrong dose (including dosing regimen, strength, form, concentration, amount) 
• Wrong route of administration 
• Wrong subject (ie, not administered to the intended subject) 
Medication errors include occurrences of overdose and underdose of the study drug. 
Overdose: Unintentional administration of a quantity of the study drug given per administration 
or per day that is above the maximum recommended dose according to the protocol. This also 
takes into account cumulative effects due to overdose (see Section 8.5 for treatment and 
reporting of overdose). For this study, any dose of vibegron of 3 or more tablets within a 24-hour 
window is an overdose. There is no known antidote for an overdose.  
Underdose: No underdose is defined for this study. 
8.5. 
Treatment of Overdose 
In the event of an overdose (3 or more tablets of study drug within 24 hours), the investigator or 
treating physician should:  
• Contact the Sponsor’s designated Medical Monitor immediately  
• Closely monitor the subject for any AEs, SAEs, and laboratory abnormalities  
• Report all overdose events on the eCRF, whether or not the overdose is associated with 
an AE. If the overdose resulted in an AE or SAE, refer to Section 10.3 for reporting 
requirements.  
• Document the quantity of the excess dose as well as the duration of the overdosing in the 
eCRF.  
Decisions regarding dose interruptions or modifications will be made by the investigator in 
consultation with the Sponsor’s designated Medical Monitor based on the clinical evaluation of 
the subject.

Statistical Considerations 
This section contains a brief summary of the statistical analyses for this study; full details will be 
provided in the Statistical Analysis Plan (SAP).  
9.1. 
Hypotheses 
9.1.1  
Primary Objective and Hypothesis 
The primary study objective is to demonstrate long-term safety of vibegron 75 mg in men with 
BPH with symptoms of OAB. There is no formal statistical primary endpoint hypothesis. 
Descriptive statistics will be used to evaluate safety endpoints, including the incidence of 
treatment-emergent AEs (SOC and PT) by originally randomized treatment group and for 
vibegron treatment overall, including events during all vibegron exposure from both Study URO-
901-3005 and URO-301-3006. 
9.1.2  
Secondary Objectives and Hypotheses 
There are no formal statistical hypotheses for this trial. The secondary study objective is to 
demonstrate long-term efficacy of vibegron 75 mg in men with BPH with symptoms of OAB.  
9.2. 
Analysis Endpoints 
The description of the endpoints and study time points at which each is measured are described 
in Section 3 and Section 1.3, respectively. 
9.2.1. 
Efficacy and Health Outcome Endpoints 
For purposes of this study, the number of micturitions will be defined as the number of times a 
subject has voided in the toilet as indicated on the Bladder Diary. Average daily micturitions are 
calculated using the daily entries in the Bladder Diary, which is completed prior to each study 
visit. Average daily number of micturitions will be calculated as the total number of micturitions 
that occur on a Diary Day divided by the number of Diary Days in the Bladder Diary. Baseline 
will be the same baseline determined from the URO-901-3005 trial. 
An urgency episode is defined as the “Need to Urinate Immediately” as indicated on the Bladder 
Diary. Average daily urgency episodes at each study visit will be calculated in the same manner 
as described above for the micturitions.  
A UUI episode is defined as having "urge" as the main reason for the leakage as indicated on the 
Bladder Diary, regardless of whether more than one reason for leakage in addition to “urge” is 
checked.  
A nocturia episode is defined as waking to pass urine during the main sleep period as indicated 
on the Bladder diary.

9.3. 
Analysis Populations 
9.3.1. 
Efficacy Analysis Populations 
The Full Analysis Set Extension (FAS-Ext) population will serve as the population for the 
analysis of efficacy data in this study. Since the endpoints related to incontinence would only 
apply to subjects who meet the definition of incontinence at study entry, it is necessary to have a 
separate FAS definition with the additional criterion to define the analysis population for 
incontinence endpoints. 
The following FAS populations are defined in this study: 
• Full Analysis Set Extension (FAS-Ext): All OAB subjects who took at least one dose of 
vibegron in the extension study and have at least one evaluable change from baseline 
micturition measurement in this study. 
• Full Analysis Set Extension for incontinence (FAS-Ext-I): All OAB subjects who took at 
least one dose of vibegron in the extension study, were included in the FAS-I population 
in the URO-901-3005 study, and have at least one evaluable change from baseline (ie, 
Study URO-901-3005 baseline) urge urinary incontinence measurement. 
Per-Protocol Extension population (PP-Ext) and Per-Protocol extension population for 
incontinence (PP-Ext-I) exclude subjects due to important deviations from the protocol that may 
substantially affect the results of the efficacy endpoints. A supportive analysis using the Per 
Protocol populations will be performed for 6 efficacy endpoints as defined in Section 3 (ie, CFB 
in micturition, urgency, nocturia, and urinary incontinence episodes; IPSS Storage score; and

volume voided per micturition). The final determination of protocol violations, and thereby the 
composition of the Per-Protocol populations will be made prior to database lock and will be 
documented. 
Using the Full Analysis Set and Per-Protocol populations, subjects will be included in one of two 
vibegron treatment groups based on the original randomization from the parent study (URO-901-
3005): vibegron for 52 weeks or vibegron for 28 weeks. Efficacy endpoints will be descriptively 
summarized by treatment group. 
9.3.2. 
Safety Analysis Populations 
The Safety Analysis Set - Extension (SAF-Ext) population will be used to for the analysis of 
safety data in this study.   
The SAF-Ext consists of all randomized subjects in Study URO-901-3005 who  
a) have completed the 24-week treatment period in the Study URO-901-3005, and  
b) enrolled into the extension Study URO-901-3006 and received at least one dose of 
vibegron in this study.   
The SAF-Ext will be used for all the safety analyses. Safety endpoints will be descriptively 
summarized based on the treatment in study URO-901-3006. This means there will be one 
vibegron treatment group (combining 52 weeks of vibegron dosing for those continuing vibegron 
from Study URO-901-3005 and 28 weeks of vibegron dosing for those who received placebo in 
Study URO-901-3005).  
No imputation will be performed for missing safety data. Baseline will be the same as the 
baseline defined in the parent study. Further inclusion of data from URO-901-3005 in the 
reporting of this study will be described in the SAP.  
9.4. 
Statistical Analyses 
9.4.1. 
Statistical Methods for Efficacy Analysis 
Statistical analysis of efficacy endpoints will be for descriptive purposes only. Baseline will be 
defined as the baseline from the Study URO-901-3005. Further inclusion of data from URO-901-
3005 in the reporting of this study will be described in the SAP. 
For the analysis of continuous change from baseline endpoints (eg, change from baseline in 
average number of micturitions, change from baseline in the average number of urgency 
episodes, change from baseline in average number of nocturia episodes, change from baseline in 
daily urge urinary incontinence episodes, change from baseline in average IPSS Storage score, 
and change from baseline in average volume voided per micturitions), a mixed model for 
repeated measure (MMRM) with restricted maximum likelihood estimation will be used. This 
model corrects for dropout and accounts for the fact that measurements taken on the same 
subject over time tend to be correlated, by using all available information on subjects within the 
same covariate set to derive an estimate of the treatment effect for a dropout-free population.

The analysis model for each efficacy endpoint will include terms for visit, baseline, stratification 
factors (only those that were statistically significant in URO-901-3005 will be included in the 
models), and baseline score. Only subjects on active treatment in both URO-901-3005 and URO-
901-3006 will be included in the model. Adjusted means and 95% confidence intervals will be 
presented for each visit.   
An unstructured covariance matrix will be used to model the correlation among repeated 
measurements. The Kenward-Roger adjustment will be used with restricted (or residual 
maximum likelihood (REML) to make proper statistical inference. If the unstructured covariance 
model fails to converge with the default Newton-Raphson algorithm, the Fisher scoring 
algorithm or other appropriate methods can be used to provide initial values of the covariance 
parameters. In the rare event that none of the above methods yield convergence, a structured 
covariance will be used to model the correlation among repeated measurements. 
In general, continuous variables will be summarized by treatment to indicate the population 
sample size (N), number of subjects with available data (n), arithmetic mean, SD, median, Q1, 
Q3, minimum, and maximum values. Categorical variables will be summarized by N, n, number 
of subjects in each category, and the percentage of subjects in each category. Unless otherwise 
noted, the denominator to determine the percentage of subjects in each category will be based on 
the number of subjects with available data. 
9.4.2. 
Safety Analyses 
Safety analysis will be conducted using the SAF-Ext population and summarized by the 
Vibegron treatment group.  The treatment-emergent period will be defined as the period of time 
from the first dose date of vibegron in this study through 21 days after the last dose of treatment, 
or the date of initiation of another investigational agent or surgical intervention, whichever 
occurs first.  Safety will be assessed through summaries of adverse events, the frequency of 
treatment discontinuation due to adverse events, and clinical laboratory evaluations. 
AEs will be coded using the latest version of MedDRA (20.0 or higher). The severity of all 
adverse events will be evaluated by the Investigator. The incidence of adverse events will be 
presented by system organ class and preferred term, relationship to study treatment and severity.  
Laboratory data will consist of chemistry, hematology and urinalysis data. Only data collected by 
the central laboratory will be included in the analysis.  
Descriptive statistics of observed values and change from baseline for vital signs and post void 
residual urine volume will be listed and summarized. 
9.5. 
Multiplicity 
All efficacy endpoints will be considered descriptive and no multiplicity adjustments will be 
performed for these endpoints.

Sample Size Determination 
Approximately 300 subjects rolling over from Study URO-901-3005, in addition to other long-
term safety data with vibegron, is sufficient to characterize the long-term safety profile of 
vibegron 75 mg once daily men with symptoms of OAB on stable doses of pharmacological 
therapy for BPH. With the assumption of approximately 33% dropout, 100 subjects will be 
expected to complete the study for the duration of 1-year on vibegron.

Study and Site Closure 
The Sponsor designee reserves the right to close the study site or terminate the study at any time 
for any reason at the sole discretion of the Sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies 
have been collected and a study-site closure visit has been performed. 
The investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study site by the Sponsor or investigator may include but are 
not limited to: 
• Failure of the investigator to comply with the protocol, the requirements of the IRB/IEC/REB 
or local health authorities, the Sponsor’s procedures, or GCP guidelines 
• Inadequate recruitment of subjects by the investigator 
• Discontinuation of further study drug development 
10.1.10. Publication Policy 
• The Sponsor has proprietary interest in this study. Authorship and manuscript composition 
will reflect joint cooperation between multiple investigators and sites and Sponsor or 
designee personnel. Authorship will be established prior to the writing of the manuscript. As 
this study involves multiple centers, no individual publications will be allowed prior to 
completion of the final report of the multicenter study except as agreed with the Sponsor. 
• The Sponsor will comply with the requirements for publication of study results. In 
accordance with standard editorial and ethical practice, the Sponsor will generally support 
publication of multicenter studies only in their entirety and not as individual site data. 
10.1.11. Compliance with Protocol 
The investigator is responsible for compliance with the protocol at the investigational site. A 
representative of the Sponsor will make frequent contact with the investigator and his/her 
research staff and will conduct regular monitoring visits at the site to review subject and study 
drug accountability records for compliance with the protocol. Protocol deviations will be 
discussed with the investigator upon identification. The use of the data collected for the subject 
will be discussed to determine if the data are to be included in the analysis. The investigator will 
enter data that may be excluded from analysis as defined by the protocol deviation specifications. 
Significant protocol deviations will be reported to the IRB/IEC/REB according to the 
IRB/IEC/REB’s reporting requirements.

Appendix 2: Clinical Laboratory Tests 
The tests detailed in Table 10-1 will be performed by the central laboratory chosen by the 
Sponsor. Subjects do not need to fast prior to laboratory testing. A sample for urinalysis 
(including microscopy for RBCs, WBCs, epithelial cells, and bacteria) and urine culture will be 
sent to the central laboratory only if the urine dipstick tests positive for the presence of 
leukocytes, nitrites, or blood cells. If a subject reports symptoms suggestive of a urinary tract 
infection at any visit, a urine dipstick should be performed as needed, and a sample will be sent 
out for urinalysis and culture and sensitivity testing.

Appendix 14: Patient-Reported Outcomes Questionnaires, 
Descriptions, and Instructions 
Information on each of the scales and questionnaires for patient-reported outcomes are provided 
below. A sample for each assessment is also provided. 
10.8.1. 
International Prostate Symptom Score (IPSS) 
The International Prostate Symptom Score (IPSS) is based on the answers to 7 questions 
concerning urinary symptoms and 1 question concerning quality of life. Each question 
concerning urinary symptoms allows the subject to choose 1 out of 6 answers indicating 
increasing severity of the particular symptom. The answers are assigned points from 0 to 5. The 
total score can therefore range from 0 to 35 (asymptomatic to very symptomatic). 
The questions refer to the following urinary symptoms: 
Questions 
Symptom 
1 
Incomplete emptying 
2 
Frequency 
3 
Intermittency 
4 
Urgency 
5 
Weak Stream 
6 
Straining 
7 
Nocturia 
Question 8 refers to the subject’s perceived quality of life. 
The first 7 questions of the I-PSS are identical to the questions appearing on the American 
Urological Association (AUA) Symptom Index which currently categorizes symptoms as 
follows: 
Mild (symptom score ≤ 7) Moderate (symptom score range 8 to 19) Severe (symptom score 
range 20 to 35) 
The answers to the single question to assess the quality of life this question range from 
“delighted” to “terrible” or 0 to 6.  Although this single question may or may not capture the 
global impact of BPH Symptoms or quality of life, it may serve as a valuable starting point for a 
doctor-patient conversation.
