Study Design 
This is an international, Phase 3, randomized, double-blind, placebo-
controlled with active control (tolterodine), parallel-group, multicenter 
study to evaluate the safety, tolerability, and efficacy of vibegron 75 mg
in men and women with symptoms of overactive bladder (OAB). 
Approximately 1,400 men and women with overactive bladder will be 
enrolled at approximately 330 study sites. 
At Baseline, patients who meet all eligibility criteria are randomized 
5:5:4 to receive either vibegron 75 mg, placebo, or tolterodine ER 4 mg 
in a double-blind fashion.  Between the Baseline and Week 12 Visits, 
patients will attend Visits at Weeks 4 and 8. 
This study consists of a Screening Period (1 to 5 weeks), a single-blind 
Run-in Period (2 weeks), a randomized double-blind Treatment Period 
(12 weeks), and a Safety Follow-up Period (4 weeks).  Patients who 
complete the Week 12 Visit may be offered the opportunity to enroll in 
a 40-week double-blind extension study RVT-901-3004 (which will be 
conducted under a separate protocol), until enrollment in that study is 
complete.  Patients who do not enroll into the optional extension study 
will have a Follow-up Visit approximately 28 days after the patient’s 
last dose of Study Treatment (i.e., at Week 16 for patients who 
complete the Week 12 Visit, or approximately 4 weeks after withdrawal 
for patients who discontinue the study early).  Additionally, 
Unscheduled Visit(s) may be arranged for patients with study-related 
safety concerns as needed. 
Study Treatments 
All treatments are dosed orally, once daily (QD).  Patients are 
randomized to one of the following blinded treatments: 
 Vibegron 75 mg tablet + placebo capsule to match tolterodine ER 
4 mg capsule (N = 500) 
 Placebo tablet to match vibegron 75 mg tablet + placebo capsule to 
match tolterodine ER 4 mg capsule (N = 500) 
 Tolterodine ER 4 mg capsule + placebo tablet to match vibegron 
75 mg tablet (N = 400) 
Duration of 
Treatment 
12 weeks

Statistical Methods 
 
Efficacy Analyses 
For the analysis of the co-primary endpoints (change from baseline in 
average number of daily micturitions at Week 12 and change from 
baseline in average number of daily UUI episodes at Week 12), a mixed 
model for repeated measure (MMRM) with restricted maximum 
likelihood estimation will be used.  The analysis model for each 
efficacy endpoint will include terms for treatment, visit, OAB Type 
(Wet vs Dry), Sex (Female vs Male), Region (US vs Rest of World), 
baseline score, and interaction of visit by treatment.  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. 
Other change from baseline endpoints will be analyzed using the same 
MMRM model. 
Response efficacy endpoints (proportion of patients with at least 75% 
reduction or 100% reduction in the average number of daily UUI 
episodes at Week 12 and proportion of patients with at least 50% 
reduction in the average number of daily urgency episodes at Week 12) 
will be analyzed using the Cochran-Mantel-Haenszel risk difference 
estimate.  Missing Week 12 data will be analyzed using multiple 
imputation.  For each imputed dataset, the estimated difference in the 
proportion of responders and 95% confidence interval for the difference 
will be calculated using the Cochran-Mantel-Haenszel risk difference 
estimate stratified by OAB Type (Wet vs Dry) and Sex (Female vs 
Male), with weights proposed by Greenland and Robins.

The key secondary endpoints will be tested using a hierarchical testing 
strategy using two-
multiplicity is needed. 
Safety Analyses 
Safety assessments (e.g., adverse events, clinical laboratory 
assessments, vital signs) will be summarized using descriptive statistics. 
No formal statistical comparisons will be performed. 
Power and Sample 
Size 
Approximately 1,400 patients will be randomized in a 5:5:4 ratio to 
receive one of the following Study Treatments: 
 Vibegron 75 mg tablet + placebo capsule to match tolterodine ER 
4 mg capsule (N = 500) 
 Placebo tablet to match vibegron 75 mg tablet + placebo capsule to 
match tolterodine ER 4 mg capsule (N = 500) 
 Tolterodine ER 4 mg capsule + placebo tablet to match vibegron 
75 mg tablet (N = 400) 
Approximately 500 patients will be assigned to the vibegron and 
placebo treatment groups, and approximately 400 patients will be 
assigned to the tolterodine treatment group.  Assuming a total of 10% 
patients will discontinue prior to Week 12 (for any reason), there will 
be approximately 450 evaluable patients in the vibegron and placebo 
treatment groups at the end of Week 12.  Assuming 75% of the 
population will have OAB Wet, there will be approximately 
337 evaluable patients in the vibegron and placebo treatment groups for 
the incontinence endpoints.  The study has: 
 Approximately 98% power to detect a true underlying between-
group treatment difference of 0.6 in change from baseline in 
micturitions at a two-sided 0.05 level assuming a variability 
estimate of 2.20 based on vibegron Study 008 data. 
 Approximately 98% power to detect a true underlying between-
group treatment difference of 0.51 in change from baseline in UUI 
episodes at a two-sided 0.05 level assuming a variability estimate 
of 1.68 based on vibegron Study 008 data. 
Assuming that these endpoints are uncorrelated, then this study has 
96% power to reject both co-primary hypotheses.

INTRODUCTION 
2.1. 
Indication 
Vibegron (RVT-901) is currently in development to reduce urge urinary incontinence, urgency, 
and urinary frequency in patients with overactive bladder (OAB). 
2.2. 
Background 
OAB affects approximately 16% of the population in the US and EU.  Prevalence increases with 
age, affecting approximately 1/3 of people 75 y
Stewart, 2003; Milsom, 2001 .  
The International Continence Society (ICS) defines OAB as urgency, with or without urge 
Abrams, 2002 .  Urgency is 
defined as a sudden compelling desire to void which is difficult to defer.  Urge urinary 
incontinence (UUI) is the involuntary loss of urine accompanied by urgency (referred to as OAB 
Wet) and is present in approximately one-
Stewart, 2003; 
Milsom, 2001 .  In the absence of incontinence, OAB is referred to as OAB Dry.  UUI is 
distinguished from stress urinary incontinence, which is the involuntary loss of urine on effort or 
physical exertion (e.g., sporting activities), or on sneezing or coughing.  When both components 
are present, the classification is mixed urinary incontinence and the Investigator will make a 
determination of either urgency or stress specified as the predominant component. 
Currently, the predominant class of drugs used to treat OAB is antimuscarinics.  The clinical use 
of antimuscarinics is limited by modest efficacy and poor tolerability due to mechanism-based 
side effects including dry mouth, constipation, and the potential for CNS adverse effects 
(e.g., cognitive impairment).  High discontinuation rates have been observed for both tolterodine 
and oxybutynin, two commonly prescribed antimuscarinics, in both clinical trials and marketed

prescriptions for tolterodine ER or oxybutynin, the mean time to discontinuation was 45 to 
60 
Lawrence, 2000 .  At 
six months, less than 1/3 of patients were still refilling their prescriptions.  The lack of efficacy 
or inability to tolerate antimuscarinics leaves patients with few alternative treatment options.  As 
such, there is a clear unmet medical need for better treatment options for patients with OAB.  In 
addition, recent evidence from observational studies suggests that higher cumulative 
anticholinergic use is associated with an increased

2.3. 
Non-clinical Safety Summary 
Nonclinical safety evaluation of vibegron included a comprehensive package of safety 
pharmacology, repeat-dose oral toxicity up to the chronic duration, genetic toxicology, 
carcinogenicity, reproductive developmental, and special safety studies to support the continued 
evaluation of long-term oral administration of vibegron in humans. 
Cardiovascular safety pharmacology findings consisted of increased heart rates, decreased QT 
interval, and increased corrected QT (QTc) 
 2.5 mg/kg); the QRS interval and diastolic 
blood pressure were increased in monkeys at 135 mg/kg.  At 2.5 mg/kg in monkeys, the 
maximum concentration (Cmax) level was less than the estimated human exposure at 75 mg.  All 
safety pharmacology changes were transient, and QT changes in the nonclinical model did not 
translate to humans.  A clinical thorough QT (tQT) study did not identify clinically meaningful 
effects on QTc interval or blood pressure when evaluated up to the supratherapeutic dose of 
400 mg. 
Additional findings included neurobehavioral effects of reduced mobility with abnormal posture 
0 mg/kg (34-fold of Cmax at the 75 mg); and increased respiration rates and 
 2.5 mg/kg. 
In chronic toxicity studies, findings were limited to a transient clinical sign of salivation, a 
decreased body weight gain in rats, and a higher incidence of abdominal distension in monkeys.  
In monkeys, histopathology changes consisted of a slight cellular infiltration in the liver, which 
correlated with hepatic enzyme elevation in the 3-month study.  Systemic exposures at no-
observed-adverse-effect levels (NOAELs) in rats were 3- and 32-fold higher in males and 
females, respectively, compared to the gender-specific human exposures.  In monkeys, the 
NOAEL was 21-fold higher than human exposure. 
Vibegron was not phototoxic, genotoxic, or carcinogenic.  The carcinogenicity NOAELs were at 
least 27- and 23-fold higher in mice and rats, respectively, compared to the human exposure.  
Fertility and embryo-fetal developmental findings consisted of reduced fertility in female rats

and an increased incidence of delayed skeletal ossification in fetuses of rabbits at a maternally 
toxic dose.  The reproductive developmental NOAELs were greater than 349-fold of the human 
exposure.  The nonclinical safety data supports the Phase 3 clinical studies of the proposed dose 
of 75 mg/day. 
2.4. 
Summary of Relevant Clinical Experience with Vibegron 
As of 03 February 2017, approximately 2,300 patients and healthy volunteers (including 
approximately 1,840 patients with OAB and 460 healthy volunteers) have received at least one 
dose of vibegron in 19 completed studies.  Vibegron has been evaluated in 16 Phase 1 studies, 
one large international Phase 2 dose-ranging study in patients with OAB (Study 008), and two 
completed Phase 3 studies in Japanese patients with OAB (Study 301 and 302).  A summary of 
available clinical data is included below.  Refer to the vibegron Clinical Investigator’s Brochure 
for additional information. 
2.4.1. 
Efficacy 
The efficacy of vibegron in the treatment of OAB has been assessed in one international Phase 2 
(008) and 2 Phase 3 studies (301 and 302).  A brief summary of these studies is included below. 
Study 008 was an international, randomized, placebo- and active-controlled Phase 2 dose-
ranging study conducted in 1,395 patients with OAB.  Patients were equally randomized in a 
double-blind fashion to 8 weeks of treatment in the following study arms:  vibegron 3 mg, 
15 mg, 50 mg, or 100 mg once daily, tolterodine ER 4 mg once daily, or placebo once daily.  An 
optional extension study for eligible patients continued vibegron (50 and 100 mg) and tolterodine 
treatment for a total duration of 52 weeks.  Treatment of patients with OAB with vibegron 
resulted in a dose-dependent reduction in the average daily number of micturitions, total urinary 
incontinence episodes, UUI episodes, and urgency episodes.  At doses of 50 and 100 mg of 
vibegron, statistically and clinically relevant lowering of important OAB endpoints was observed 
(Table 2). 
Kyorin Pharmaceutical Company (Kyorin) has conducted a development program in Japan, 
consisting of two large Phase 3 clinical trials (Studies 301 and 302).  Overall, 908 patients were 
treated with vibegron in the Kyorin Phase 3 program. 
Study KRP114V-T301 (Study 301) was a double-blind, randomized, placebo controlled, multi-
center, Phase 3 study designed to evaluate the safety and efficacy of vibegron in Japanese males 
and females with OAB.  Upon completion of the placebo Run-in period, 1,232 patients were 
randomized to receive blinded study treatment for 12 weeks including:  vibegron 50 mg 
(N=370), vibegron 100 mg (N=369), placebo (N=369), or imidafenacin 0.2 mg (comparator; 
N=117).  Study 301 results demonstrate that once daily vibegron produced statistically 
significant reductions in efficacy parameters including:  micturitions, UUI episodes, total 
incontinence episodes, and urgency episodes (Table 2). 
Study KRP114V-T302 (Study 302) was an open-label, uncontrolled, multi-center, Phase 3 study 
designed to evaluate the long-term (52-week) safety and efficacy of vibegron in Japanese males 
and females with OAB.  Upon completion of a 1-week observation period, 169 patients initiated 
vibegron 50 mg once daily.  After eight weeks, the dose could be increased to 100 mg once daily 
as clinically indicated.  Patients continued vibegron at a dose of 50 mg or 100 mg through

Week 52.  Once daily vibegron reduced episodes of micturitions, UUI episodes, total 
incontinence episodes, and urgency episodes over a 52-week treatment period.

2.4.2. 
Safety and Tolerability 
The safety of vibegron has been evaluated in 19 clinical studies.  Over 450 subjects have 
received vibegron in Phase 1 clinical trials and over 1,900 patients have received vibegron in 
Phase 2 and 3 trials for overactive bladder.  In addition to this overview, please refer to the 
Clinical Investigator’s brochure for an in-depth review of the safety profile. 
In 16 Phase 1 clinical studies, vibegron was well-tolerated following single dose administration 
of doses up to 600 mg and following multiple dose administration of doses up to 400 mg for 
14 days and 150 mg for 28 days.  In healthy volunteers, at doses  100 mg, vibegron was 
associated with increases in heart rate and blood pressure and occasional orthostatic symptoms.  
There were no serious adverse events in the Phase 1 program and most adverse events (AEs) 
were mild or moderate in intensity and transient.  There were no clinically meaningful changes in 
laboratory safety or ECG parameters with vibegron alone or when co-administered with 
tolterodine.  A clinical tQT/QTc study did not identify clinically meaningful effects on QTc 
interval or blood pressure.

There have been two large placebo-controlled studies with vibegron, as well as two 52-week 
long-term safety studies.  The first placebo controlled trial, conducted by Merck, was a 2-part 
Phase 2 clinical study (Study 008); this also included an open-label 1-year extension in which 
1,395 patients were enrolled, of whom 976 received treatment with vibegron.  This study was 
designed to assess the safety, tolerability, and efficacy of vibegron, and to provide proof-of-
concept for concomitant dosing with tolterodine ER 4 mg.  Part 1 evaluated once-daily doses of 
vibegron ranging from 3 to 100 mg, tolterodine ER 4 mg, or placebo for 8 weeks and 
concomitant dosing of vibegron 50 mg with tolterodine ER 4 mg for 4 weeks.  Part 2 evaluated 
once daily doses of vibegron 100 mg, tolterodine ER 4 mg, vibegron 100 mg with tolterodine ER 
4 mg, or placebo once daily for 4 weeks.  The most common adverse events for vibegron were 
dry mouth, headache, urinary tract infection, and nasopharyngitis, all of which were reported at 
< 5.5%.  These AE rates were similar to the placebo and tolterodine ER 4 mg treatment groups.  
Assessment of safety laboratory parameters and mean vital sign values over time, including heart 
rate and blood pressure, showed no meaningful differences for any active treatment group 
relative to placebo. 
Vibegron was generally well-tolerated during 52 weeks of treatment in the extension phase of 
Study 008 when administered alone or when co-administered with tolterodine, with no 
meaningful differences in the overall incidence or severity of adverse events observed among the 
treatment groups compared to placebo or in the combination treatment groups compared to either 
monotherapy. 
Results from the Kyorin Study 301 demonstrated that both the 50 and 100 mg vibegron dose 
levels were well-tolerated in these 12-week studies.   The incidence of AEs in vibegron treatment 
groups was similar to the placebo group, and the data showed a similar safety profile as observed 
in Study 008.  Nasopharyngitis was the most commonly reported adverse event (7.3% in the 
placebo group; 8.6 and 9.5% of patients in the 50 and 100 mg vibegron dose groups, 
respectively).  Dry mouth occurred in 0.5% of patients in the placebo group, and in 1.4% and 
0.5% of patients in the 50 and 100 mg vibegron dose groups, respectively.  Cystitis was reported 
in 0.8% of patients in the placebo group, and in 2.4% and 2.2% of patients in the 50 and 100 mg 
vibegron dose groups, respectively. 
In a 52-week long term administration open-label study (Study 302), where patients had the 
option to increase their treatment dose from 50 to 100 mg, there were no trends toward increased 
frequency of AEs in 51 of the 169 vibegron-treated patients who elected to increase their dose. 
In summary, data from Phase 1 through 3 clinical trials suggest that vibegron is generally safe 
and well- tolerated, when administered alone or when co-administered with the following drugs:  
antimuscarinics (imidafenacin or tolterodine); metoprolol (a representative beta-blocker); or 
amlodipine (a representative vasodilator).  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.  Discontinuation rates due to adverse events were low (less than 5%) in all clinical 
studies. 
These data support the ongoing evaluation of vibegron monotherapy in clinical safety and efficacy 
studies for the treatment of patients with symptoms of overactive bladder.

2.4.3. 
Clinical Pharmacology, Pharmacokinetics, and Metabolism 
Results of Phase 1 absorption distribution metabolism and excretion study 011, which evaluated 
a single-dose of 14C-vibegron 100 mg in 6 subjects suggested that, found that the majority of 
vibegron was eliminated as parent indicating minimal metabolism.  Approximately 30% and 
50% of the absorbed dose was eliminated through renal and hepatic routes, respectively.  Based 
on preclinical and preliminary clinical data, vibegron is metabolically stable and while 
CYP3A4 is likely the predominant cytochrome P450 (CYP) responsible for in vitro metabolism, 
metabolism appears to only play a minor role (< 10%) in the elimination of vibegron. 
Pharmacokinetic (PK) data in young, middle-aged and elderly males and females with vibegron 
suggest good absorption with non-linear pharmacokinetics.  Vibegron time to reach maximum 
concentration (tmax) values are generally similar across age groups and across genders, ranging 
from 1 to 3 hours.  Preliminary data suggest that the area under the concentration-time curve 
from time 0 to 24 hours (AUC0-24hr) and Cmax increase in a greater than dose-proportional manner 
as a result of an increase in bioavailability with increasing dose, possibly due to saturable 
P-glycoprotein (P-gp)-mediated efflux in the gut.  Vibegron plasma concentrations are higher in 
females compared to males, in Japanese compared to non-Japanese and in elderly compared to 
middle aged and young.  Exposures are similar in middle-aged males when compared to young 
males.  The harmonic mean apparent terminal half-life (t½) values following multiple-dose 
administration range from 59 to 94 hours, with accumulation half-lives of 25 hours and 38 hours 
in young and elderly subjects, respectively.  Steady state trough concentrations appeared to have 
been approached by Day 7 across age groups.  The steady state area under the concentration-time 
curve (AUC) geometric mean accumulation ratios were ~2 in young males and ~2.8 in the elderly 
(males and females).  Food and ethnicity do not meaningfully alter the pharmacokinetic profile 
of vibegron. 
2.5. 
Study Rationale 
The use of vibegron in a large Phase 2b study (Study 008) in patients with OAB has 
demonstrated encouraging safety, tolerability, and efficacy results.  Furthermore, Phase 3 data in 
Japan (Studies 301 and 302) have demonstrated that vibegron is a safe, well tolerated, and 
effective therapy for OAB patients.  Given there are still OAB patients that do not reach their 
treatment goals with currently approved therapies, there remains an unmet need for new OAB 
therapies with a favorable safety, tolerability, and efficacy profile.  This study is designed to 
evaluate the safety, tolerability, and efficacy of vibegron 75 mg administered once daily in 
patients with OAB. 
2.6. 
Dose Rationale 
Clinical and non-clinical data support selection of a Phase 3 dose of vibegron 75 mg 
administered once daily in patients with OAB.  This pivotal Phase 3 study is designed to 
establish the safety, tolerability, and efficacy profile of vibegron 75 mg administered once daily 
in patients with OAB. 
Several lines of evidence support evaluating a once daily 75 mg vibegron dose:  1) Study 008, a 
large Phase 2b dose ranging study, and two Phase 3 studies (Study 301 and Study 302) 
demonstrated that doses up to 100 mg for 52 weeks are safe and well tolerated in patients with

OAB; 2) Study 008 demonstrated dose-dependent efficacy across multiple clinical endpoints in 
OAB patients with the maximal effect generally estimated between 50 and 100 mg; 75 mg of 
vibegron is expected to capture approximately 90% of the efficacy of 100 mg; 3) slight increases 
in mean maximum heart rate and infrequent increases in systolic or diastolic blood pressure in 
patients with OAB were difficult to detect relative to placebo and were not readily 
distinguishable between 50 and 100 mg of vibegron; these effects appear similar to, or less than, 
marketed agents tolterodine ER 4 mg and mirabegron 50 mg; and 4) vibegron exhibits greater 
than dose-proportional increases in exposures with mean Cmax increasing ~4-fold when dose 
increases from 50 to 100 mg.  A simulated dose of 75 mg decreases Cmax by approximately 40% 
and reduces extremes of exposure compared to 100 mg.  Lowering Cmax should maximize the 
benefit-risk profile for patients with OAB by minimizing the potential for heart rate or blood 
pressure increases. 
2.7. 
Information on Other Study-Related Therapies 
Placebo 
The European Medicines Agency (EMA) Committee for Medicinal Products for Human Use 
(CHMP) Note for Guidance on the Clinical Investigation of Medicinal Products for the 
Treatment of Urinary Incontinence recommends that OAB trials include a placebo arm to 
account for the recognized large placebo responses commonly observed in these studies 
EMA, 2002 .  To accurately demonstrate and measure the true efficacy of vibegron, a placebo 
arm will be included in this study.  Furthermore, a single-blind Run-in Period will be used to 
assess the early placebo response and to ensure that patients have adequate experience with the 
Patient Voiding Diary prior to starting the blinded Treatment Period of the study. 
Tolterodine ER 
Tolterodine ER is an antimuscarinic approved for the treatment of overactive bladder and will be 
administered at the recommended labeled dose of 4 mg once daily (QD) orally.  In this study, 
tolterodine ER 4 mg will be used as an active control.

INVESTIGATIONAL PLAN 
4.1. 
Overall Study Design 
This is an international, Phase 3, randomized, double-blind, placebo-controlled with active 
control (tolterodine), parallel-group, multicenter study in men and women with overactive 
bladder, to be conducted in conformance with International Conference on Harmonisation of 
Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) Good 
Clinical Practice.  Enrollment of patients will include individuals with OAB Wet (those with 
UUI, the involuntary loss of urine accompanied by urgency) and OAB Dry (those without UUI). 
The study consists of a Screening Period (1 to 5 weeks), a single-blind Run-in Period (2 weeks), 
a randomized double-blind Treatment Period (12 weeks), and a Follow-up Period (4 weeks).  
Patients who complete the Week 12 Visit may be offered the opportunity to enroll in a 40-week 
double-blind extension study (RVT-901-3004), which will be conducted under a separate 
protocol, until enrollment in that study is complete.  Patients who do not enroll into the optional 
extension study will have a Follow-up Visit approximately 28 days after the patient’s last dose of 
Study Treatment (i.e., at Week 16 for patients who complete the Week 12 Visit, or 
approximately 4 weeks after withdrawal for patients who withdraw early from study 
participation).  Additionally, Unscheduled Visit(s) may be arranged at any time during the study 
for patients with study-related safety concerns, as needed. 
The study will assess the safety, tolerability, and efficacy of 75 mg vibegron versus placebo.  
Tolterodine ER 4 mg is the active control.  Patients will be randomized 5:5:4 in a double-blind 
fashion to one of three treatment arms:  vibegron 75 mg, placebo, or tolterodine ER 4 mg, all 
administered once daily for 12 weeks during the Treatment Period.  Between the Baseline and 
Week 12 Visits, patients will have study assessments at Week 4 and Week 8.  A schematic of the 
study design is shown as Figure 1. 
Specific procedures to be performed during the study, as well as their prescribed times and 
associated visit windows, are outlined in the Schedule of Activities (Table 1).  Details of study 
procedures are provided in Section 7. 
A schematic of the study design is shown as Figure 1.

4.2. 
Treatment Arms and Duration 
Refer to Section 6 for full details of Study Treatments.  Patients will be randomized 5:5:4 to one 
of the following blinded treatments during this study: 
 Vibegron 75 mg tablet + placebo capsule to match tolterodine ER 4 mg capsule; both 
oral and administered once daily 
 Placebo tablet to match vibegron 75 mg tablet + placebo capsule to match tolterodine 
ER 4 mg capsule; both oral and administered once daily 
 Tolterodine ER 4 mg capsule + placebo tablet to match vibegron 75 mg tablet; both 
oral and administered once daily 
Dosing will begin at the Baseline Visit (Day 1), and once daily dosing of the Study Treatment 
will continue through Study Day 84, the day before the Week 12 Visit. 
Patients who complete the Week 12 Visit may be offered the opportunity to enroll in a 40-week 
double-blind extension study RVT-901-3004 (which will be conducted under a separate 
protocol), until enrollment in that study is complete. 
4.3. 
Number of Participants 
Approximately 1,400 patients will be enrolled at approximately 330 study sites. 
4.4. 
Definition of Study Completion by a Patient 
A patient is considered to have completed the study if she/he completes the Week 12 Visit. 
4.5. 
End of Study Definition 
End of study is defined as the date when the last patient has either completed the study 
(see Section 4.4 for definition of completion), has discontinued from the study, or is lost to 
follow-up (i.e., the patient is unable to be contacted by the Investigator).

 sexual partner(s) who was vasectomized at least 6 months prior to the Screening 
Visit 
 sexual abstinence from heterosexual intercourse, as a preferred lifestyle; periodic 
abstinence is not acceptable 
Patients will be provided with information on acceptable methods of contraception as part of the 
informed consent process and will confirm when they sign a consent form they understand the 
requirements for avoidance of pregnancy during the course of the study. 
These methods of contraception are only effective when used consistently, correctly, and in 
accordance with the product label.  The Investigator is responsible for ensuring that patients 
understand how to properly use these methods of contraception. 
5.2.2. 
Meals and Dietary Restrictions 
Patients may consume a normal, regular diet and take their Study Treatment daily without regard 
to food or other medications. 
Patients do not need to fast prior to laboratory draws. 
5.3. 
Screen Failure 
After obtaining informed consent, study site personnel will access the interactive voice or web 
response system (IxRS) to assign a unique patient number to a potential study participant. 
For patients who provide informed consent and subsequently do not meet eligibility criteria or 
withdraw consent, study site personnel should document the screen failure in the patients' source 
documents.  The documentation should include demographics and medical history, the reason for 
screen failure, the eligibility criteria reviewed, procedures performed, etc. 
For patients excluded during Screening and Run-in, the screen failure should be reported 
promptly to IxRS.

Interruption of Study Treatment 
5.4.1. 
Temporary Interruption 
The medical monitor should be contacted for Study Treatment interruption of >7 days in 
duration.  Study treatment may be temporarily interrupted for up to 21 consecutive days if 
required for adverse event management, as described in Section 6.6. 
5.4.2. 
Rechallenge 
See Section 6.6. 
5.5. 
Withdrawal from the Study 
Patients may withdraw consent at any time for any reason or be withdrawn from the study at the 
discretion of the Investigator should any untoward effect occur.  Every effort should be made to 
establish and document the possible reasons for withdrawal.  A patient may be withdrawn by the 
Investigator or the Sponsor if enrollment into the study is inappropriate, the study plan is 
violated, or for administrative and/or other safety reasons.  The patient may be discontinued from 
further study participation after discussion between the Investigator and the Sponsor clinical 
monitor (or designee) if the patient requires therapy with any excluded medication.  Medications 
that may cause a patient to be discontinued have been described in Section 7.9.3. 
A patient must be discontinued from the study for any of the following reasons: 
 The patient or legal representative (such as a legal guardian) withdraws consent. 
 Study treatment administration is interrupted for more than 21 consecutive days. 
 The patient has a medical condition or personal circumstance which, in the opinion of 
the Investigator and/or Sponsor, places the patient at unnecessary risk through 
continued participation in the study or does not allow the patient to adhere to the 
requirements of the protocol. 
 The patient has a confirmed positive serum pregnancy test. 
 The patient is unable to complete the study procedures successfully, including 
completion of the Patient Voiding Diary. 
 When a patient withdraws from the study prior to study completion, all applicable 
activities scheduled for the Week 12 Visit should be performed at the time of 
withdrawal.  Any adverse events that are present at the time of withdrawal should be 
followed in accordance with the safety requirements outlined in Section 8. 
 Once a patient is withdrawn, he/she shall not be allowed to enroll again. 
5.6. 
Lost to Follow Up 
Should a patient fail to attend a required study visit, the site should attempt to contact the patient 
and re-schedule the missed visit as soon as possible.  The site should also counsel the patient on 
the importance of maintaining the assigned visit schedule and ascertain whether or not the patient 
wishes to and/or should continue in the study based on previous non-compliance.  In cases where 
the patient 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 patient 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 patient (i.e., phone, email, or certified 
letter).  Efforts to establish the possible reason for discontinuation should be documented. 
5.7. 
Early Study Termination 
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 (GCP) 
and/or other applicable regulatory requirements, procedure-related problems or the number of 
discontinuations for administrative reasons is too high.

Throughout the study, all Study Treatments will be taken by mouth once daily in the morning 
with 8 ounces of water and should be swallowed whole.  Study treatment may be taken without 
regard to meals. 
During the Run-in Period, all patients will take placebo (1 tablet and 1 capsule) once daily for 
2 weeks prior to the Baseline Visit.  The Investigator will be aware that the Study Treatment 
during this period is placebo, however, the patient will NOT be told that the treatment 
administered during this period is placebo or that the patient needs to qualify to enter the 
randomized Treatment Period. 
Study treatments will be taken either at the site or at home as follows: 
 All patients will take their dose of Study Treatment on the day of the Run-in and 
Baseline Visits at the site as a witnessed dose. 
 Patients in the population PK subset will hold their dose of Study Treatment on the 
day of the Week 4 and Week 8 Visits. 
 All other doses of Study Treatment will be taken by the patient at home. 
If a patient forgets to take Study Treatment in the morning, the missed dose should be taken as 
soon as possible on the same calendar day.  However, if a dose is missed for an entire calendar

day, the missed dose should NOT be taken on the following calendar day.  This will be recorded 
as a missed dose. 
6.3. 
Study Treatment Assignment 
Randomization will occur centrally using an interactive voice or web response system (IxRS) 
using central, stratified randomization.  There are three treatment arms to which patients will be 
randomized in a 5:5:4 ratio: 
 Vibegron 75 mg + placebo to match tolterodine ER 4 mg 
 Placebo to match vibegron 75 mg + placebo to match tolterodine ER 4 mg 
 Tolterodine ER 4 mg + placebo to match vibegron 75 mg 
Randomization will be stratified based on baseline category of OAB Wet or OAB Dry and Sex 
(Female vs Male). 
Enrollment will be capped based on OAB Dry criteria and sex as follows: 
 Up to 25% of the patients enrolled may meet OAB Dry criteria. 
 Up to 15% of the patients enrolled may be male. 
Note:  The proportion of OAB Dry patients and male patients during Screening will 
be monitored in IxRS.  The final proportion of OAB Dry and male patients will 
depend on both number of OAB Dry or male patients in the Screening queue at the 
time the stratum is closing and on total study enrollment. 
6.4. 
Blinding 
A single-blind (Run-in only) and double-blind/masking technique will be used:  vibegron and its 
matching placebo and tolterodine ER and its matching placebo will be packaged identically so 
that treatment blind/masking is maintained.  The patient, the Investigator, and Sponsor personnel 
or delegate(s) who are involved in the treatment or clinical evaluation of the patients are unaware 
of the treatment group assignments. 
At the end of the study (including the 28-day Follow-up Period), the official, final database will 
be frozen and unblinded after medical/scientific review has been performed, and data have been 
declared final and complete.  The Sponsor will be granted access to the unblinded database in 
order to analyze the data.  A clinical study report will be prepared after all patients complete the 
study. 
6.4.1. 
Unblinding 
All efforts should be made to contact the Medical Monitor immediately if the need for emergent 
unblinding of treatment assignment is desired.  In consultation with the Medical Monitor, IxRS 
should be used for emergency unblinding treatment assignment in the event that this is required 
for patient safety. 
In the event that unblinding has occurred, the circumstances around the unblinding (e.g., date and 
reason) must be documented promptly, and the Sponsor notified as soon as possible.  Only the 
Principal Investigator or delegate and the respective patient’s code should be unblinded.  Site

personnel and Sponsor personnel directly associated with the conduct of the study should not be 
unblinded. 
6.5. 
Dose Modification 
No dose modifications are allowed. 
6.6. 
Treatment Discontinuation and Rechallenge 
Refer to Section 8.6.1 and Section 8.6.2, respectively, for information regarding temporary 
withholding or permanent discontinuation of Study Treatment in association with liver test 
abnormalities. 
Patients who experience a grade 3 or greater toxicity that is considered related to Study 
Treatment should have their treatment discontinued permanently. 
Patients who experience an adverse event grade 3 or 4 adverse event that is not related to Study 
Treatment may have their Study Treatment interrupted for a period of up to 21 consecutive days 
if the Investigator believes it is in the best interest of the patient.  (Refer to Table 6 for Criteria 
for Determining the Grade/Severity of Adverse Event Terms).  Prior to restarting study drug, the 
adverse event must have improved to grade 0, 1, or 2. 
If the adverse event that is not related to Study Treatment remains grade 3 or grade 4 after 
treatment interruption or the Investigator believes it is in the best interest of the patient, Study 
Treatment should be discontinued permanently. 
6.7. 
Packaging and Labeling 
Clinical supplies will be affixed with a clinical label in accordance with regulatory requirements.  
During the Run-in Period, patients will receive a single-blind supply of Study Treatment bottles 
to support a 2-week Run-in Period and overage.  Once randomized into the study, patients will 
receive a double-blind supply of Study Treatment bottles at each study visit during the Treatment 
Period. 
6.8. 
Preparation/Handling/Storage/Accountability 
Clinical supplies must be stored in a secure, limited-access location under the storage conditions 
specified on the label. 
Receipt and dispensing of Study Treatment must be recorded by an authorized person at the 
study site. 
Clinical supplies may not be used for any purpose other than that stated in the protocol. 
The Investigator is responsible for keeping accurate records of the clinical supplies received 
from the Sponsor or designee, the amount dispensed to and returned by the patients, and the 
amount remaining at the conclusion of the study.  These records will be monitored throughout 
the study. 
For all sites, the local country Sponsor personnel or designee will provide appropriate 
documentation that must be completed for drug accountability and return.

6.9. 
Study Treatment Compliance 
If a patient is persistently noncompliant with the Study Treatment, it may be appropriate to 
withdraw the patient from the study.  Interruptions from the protocol specified treatment plan for 
compliance (  75% or > 125%) require consultation between the Investigator and the Sponsor 
and written documentation of the collaborative decision on patient management. 
6.10. 
Study Treatment Overdose 
Refer to Section 8.3.3 for Overdose Management.  An overdose is defined as a known deliberate 
or accidental administration of Study Treatment, to or by a study patient, at a dose above that 
assigned to that individual patient according to the study protocol. 
For this study, any dose of vibegron or placebo > 2 tablets and any dose of tolterodine or placebo 
> 2 capsules within a 24-hour window (i.e., > 2 tablets and/or > 2 capsules of blinded Study 
Treatment within a 24-hour window) is an overdose.  There is no known antidote for an 
overdose. 
6.11. 
Treatment after the End of the Study 
Other than patients who participate in the RVT-901-3004 extension study, patients will not 
receive any additional treatment with the Study Treatment from the Sponsor after completion of 
the study because the indication being studied is not life-threatening or seriously debilitating 
and/or other treatment options are available.  The Investigator is responsible for ensuring that 
consideration has been given to the post-study care of the patient’s medical condition.

STUDY ASSESSMENTS AND PROCEDURES 
The Schedule of Activities (Table 1) summarizes the study assessments/procedures to be 
performed at each visit.  Individual assessments and procedures are described below. 
It may be necessary to perform these procedures at unscheduled time points if deemed clinically 
necessary by the Investigator.  Furthermore, additional evaluations/testing may be deemed 
necessary by the Investigator and/or the Sponsor for reasons related to patient safety.  In some 
cases, such evaluation/testing may be potentially sensitive in nature, and thus local regulations 
may require that additional informed consent be obtained from the patient.  In these cases, such 
evaluations/testing will be performed in accordance with those regulations. 
7.1. 
Order of Assessments 
Vital signs, followed by PRO questionnaires, will be the first procedures performed at visits that 
include PRO administration.  Blood draws should be performed after PRO administration.  A 
urine pregnancy test (with a negative result) must be done prior to randomization. 
7.2. 
Scheduling Visits 
To the extent possible, all visits should occur at the same time across the study between the hours 
of 8 am and 12 pm.  At the end of each visit, the next visit should be scheduled/confirmed.  
Every effort should be made to adhere to the visit scheduling window as described in the 
Schedule of Activities (Table 1) to ensure the patient has an adequate amount of Study 
Treatment to comply with protocol dosing instructions.  Patients will be reminded to complete 
the Patient Voiding Diary and Urine Volume Diary within the 7 days prior to their next visit. 
7.3. 
Unscheduled Visits 
Unscheduled Visits may be performed at any time during the study whenever necessary to assess 
for or follow-up on adverse events, at the patient’s request, or as deemed necessary by the 
Investigator.  The date and reason for the Unscheduled Visit should be recorded in the source 
documentation.  The specific procedures performed at these visits will be determined by the 
Investigator, as clinically indicated.  The recommended minimum procedures are indicated in the 
Schedule of Activities (Table 1). 
7.4. 
Assignment of Patient Number 
All consented patients will be issued a unique patient number that will be used to identify the 
patient for all procedures that occur.  Each patient will be assigned only one unique patient 
number.  Unique patient numbers must not be re-used for different patients.  Any patient who is 
re-screened will obtain a new original unique patient number assigned at the repeated Screening 
Visit. 
7.5. 
Screening/Washout 
 Patients requiring washout of medications (see Section 7.9.3), can begin washout 
immediately following the Screening Visit.  After the 28-day washout period, site 
staff should contact patients to begin completion of the 7-day eDiary (Patient Voiding 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018 
 
Confidential 
Page | 57 
 
Diary and Urine Volume Diary).  Patients not requiring washout can begin the 7-day 
eDiary the day after the Screening Visit. 
 After laboratory results from the Screening Visit are reviewed and found to be 
clinically acceptable, patients will be eligible to continue to the Run-in Visit.  An 
algorithm for assessing out-of-range laboratory results is in Appendix B. 
 Patients that fail Screening may be re-screened only one time when the reason for 
exclusion has resolved, such as a resolved urinary tract infection.  If a patient is 
rescreened, a unique patient number must be used.  Patients cannot be re-screened 
after receiving placebo-run in Study Treatment.  During the Screening or Run-in 
Periods, or after re-screening, if it is determined that a patient does not qualify for the 
study, he/she will be excluded.  Patients excluded during Screening should be 
reported as a screen failure promptly to IxRS. 
7.6. 
Informed Consent 
Documented consent must be obtained from each potential patient prior to participating in study 
procedures.  Consent must be documented by the patient’s dated signature on a consent form 
along with the dated signature of the person conducting the consent discussion. 
A copy of the signed and dated consent form should be given to the patient before participation 
in the study. 
The initial informed consent form, any subsequent revised written informed consent form, and 
any written information provided to the patient must receive institutional review board 
(IRB)/research ethics board (REB)/institutional ethics committee (IEC) approval/favorable 
opinion in advance of use.  The patient should be informed in a timely manner if new 
information becomes available that may be relevant to the patient’s willingness to continue 
participation in the study.  The communication of this information will be provided and 
documented via a revised consent form or addendum to the original consent form that captures 
the patient’s dated signature. 
Specifics about a study and the study population will be added to the consent form template at 
the protocol level. 
The informed consent will adhere to IRB/REB/IEC requirements, applicable laws and 
regulations and Sponsor requirements. 
7.7. 
Inclusion/Exclusion Criteria 
All inclusion and exclusion criteria will be reviewed by the Investigator or qualified designee at 
the Screening, Run-in, and Baseline Visits to ensure that the patient qualifies for the study. 
All inclusion criteria must be met and none of the exclusion criteria may apply.  No eligibility 
waivers will be granted. 
Patients found ineligible during review of inclusion/exclusion will not proceed through the 
remaining Screening process. 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018

Page | 58 
 
Inclusion/Exclusion criteria for the eDiary completion parameters will be applied to both the 
Screening eDiary (7-day eDiary period prior to the Run-in Visit), and the Run-in eDiary (7-day 
eDiary period prior to the Baseline Visit). 
Results from the Screening Visit will be used as a basis to confirm eligibility for glucose, 
aspartate aminotransferase (AST), alanine aminotransferase (ALT), and eGFR.  Urine pregnancy 
test and average blood pressure measure will be confirmed at Screening Visit and Baseline Visit 
(prior to randomization).  Concomitant medications will be reviewed at Baseline to ensure 
required stability. 
7.8. 
Medical History 
A medical history will be obtained by the Investigator or qualified designee.  Medical history 
from the 5 years prior to the Screening Visit will be collected, including all chronic and ongoing 
conditions, regardless of year diagnosed.  Medical history will include a review of any 
concurrent malignancy or history of any malignancy to confirm eligibility criteria. 
Pelvic floor physiotherapy history will be collected. 
7.9. 
Prior and Concomitant Medications 
7.9.1. 
Prior Medications 
The Investigator or qualified designee will review prior medication use, including any protocol-
specified washout requirement, and record prior medication taken by the patient within 28 days 
prior to beginning completion of the Screening eDiary. 
All medications for the treatment of OAB taken within 1 year of the Screening Visit will also be 
recorded.  Specific details on a patient’s use of prior antimuscarinic therapy including the reason 
for discontinuation will be collected. 
Medication history will be assessed for male patients with history of mild to moderate BPH to 
ensure a stable treatment regimen that meets eligibility criteria. 
7.9.2. 
Concomitant Medications 
Concomitant medications will be reviewed and recorded at each study visit from Screening 
through Week 12 and at any Unscheduled Visits.  Patients will be informed at the study start 
regarding permissible medications during the study.  The Investigator or qualified designee will 
record all medications, if any, taken by the patient during the study.  This will include initiation 
of new medications, or changes to existing/ongoing medications. 
Upon entry into the study, patients will be instructed to report the possible need for any 
prescription or nonprescription medications immediately (and before use) to the Investigator. 
7.9.3. 
Prohibited Medications and Non-Drug Therapies 
Table 4 provides a listing of specific restrictions for concomitant therapy use during the study, 
with any necessary washout periods described.  This table provides examples of prohibited drug 
categories; however, it is not a comprehensive list of all restricted medications.

Use of other concomitant therapies that are listed in Section 7.9.5 are also prohibited if the 
patient’s dose has changed in the 4 weeks prior to the Baseline Visit or if the patient plans to 
initiate or change any of these therapies during the study. 
If there is a clinical indication for any therapy that is specifically prohibited during the study, 
discontinuation from Study Treatment may be required.  The Investigator should discuss any 
questions regarding this with the medical monitor.  The final decision on any supportive therapy 
rests with the Investigator and/or the patient's primary physician.  However, the decision to 
continue the patient on Study Treatment requires the mutual agreement of the Investigator, the 
Sponsor, and the patient. 
Consult the medical monitor if there is any uncertainty regarding patient use of a particular drug 
or drug class.

Requirements for Use of Stable Therapies 
Patients who are receiving any of the therapies from the list below must have been on a stable 
 28 days prior to Baseline to be eligible to enroll in the study.  Additionally, patients 
who plan to initiate or change any of the following therapies during the study are not eligible to 
enroll in the study: 
 Tricyclic antidepressants or combinations, including, but not limited to, amitriptyline, 
imipramine, and doxepin. 
 Alpha-1-antagonists, unless used for BPH treatment, in which case, stable dosing for 
3 months is required. 
 Serotonin and/or norepinephrine reuptake inhibitors, including, but not limited to, 
fluoxetine, paroxetine, and duloxetine. 
 Alpha-adrenergic agonists, including nonspecific sympathomimetic amines, such as, 
but not limited to, ephedrine, pseudoephedrine, and phenylephrine. 
 Diuretic therapy, including, but not limited to, furosemide and hydrochlorothiazide. 
 Inhaled anticholinergic, including, but not limited to, tiotropium bromide and 
ipratropium bromide. 
 Regular use of phosphodiesterase type 5 (PDE 5) inhibitors, including, but not limited 
to, tadalafil, sildenafil, and vardenafil. 
Note:  Occasional use of PDE 5 inhibitors (e.g., for the treatment of erectile 
dysfunction) is allowed throughout the study. 
Male patients with mild to moderate BPH without evidence of bladder obstruction as determined 
by the Investigator may be included as long as they have been taking a medication for the 
treatment of BPH for at a least 1-year prior to Baseline, with no change in dose of herbal 
medications, alpha antagonist medications, or other symptomatic treatments or medications 
within 3 months prior to Baseline.  To be eligible for the study, these BPH medication/s must be 
stable from Screening until Baseline Visit. 
Patients with a history of hypertension must be on a stable blood pressure treatment regimen for 
90 days prior to the Baseline Visit and must be deemed by the Investigator and/or Medical 
Monitor as safe to proceed in this study and able to complete the study per protocol. 
Patients with a history of cerebral vascular accident, transient ischemic attack, unstable angina, 
myocardial infarction, coronary artery interventions (e.g., coronary artery bypass grafting or

e.g., angioplasty, stent ins
interventions (e.g., carotid artery stenting) should be on stable medical therapy for at least 
3 months prior to the Screening Visit until the Baseline Visit and anticipated to be stable 
throughout the study. 
7.9.6. 
Washout of Prior Medications 
All consented patients meeting the Screening Visit entry criteria that are taking certain 
medications (as outlined in Section 7.9.3) will be required to begin wash-out of these 
medications following the Screening Visit for a minimum of 28 days prior to beginning 
completion of the Screening Patient Voiding Diary.  These medications must not be used from 
the point of initiation of washout following the Screening Visit, through the Week 12 Visit. 
7.10. 
Patient Voiding Diary 
The Patient Voiding Diary is used by participants (via the eDiary or paper Diary) to record the 
frequency of daily OAB symptoms including all micturitions, urgency, incontinence, and main 
reason for incontinence by selecting the respective box for each symptom occurring during the 
course of a given day and night. 
The Patient Voiding Diary should be completed by the patient on all of the 7 days prior to the 
Run-in Visit, Baseline Visit, Week 2 (diary only; no clinic visit), and the Weeks 4, 8, and 12 
Visits. 
Patients will complete the Patient Voiding Diary between the Screening Visit and Run-in Visit 
(over the 7 days prior to the Run-in Visit).  After the Screening Visit, patients not requiring 
wash-out can begin the Patient Voiding Diary the morning after the Screening Visit (upon 
getting up for the day).  Patients requiring wash-out of medications can begin completing the 
Patient Voiding Diary after the 28-day wash-out period. 
Patients will also complete the Patient Voiding Diary between the Run-in Visit and the Baseline 
Visit (over the 7 days prior to the Baseline Visit, while the patient is taking Run-in Study 
Treatment). 
A “Diary Day” is defined as the time between when the patient gets up for the day each morning 
(i.e., the time the patient got up for the day yesterday to the time the patient got up for the day 
today; approximately a 24-hour period). 
A “Complete Diary Day” is defined as a Diary Day for which the patient indicates that they 
have recorded all urinations and any leakages that occurred during that Diary Day.  Specifically, 
on the eDiary the patient will respond Yes to the corresponding item in the Begin Day 
Questionnaire to indicate that their data are complete for the preceding Diary Day. On the paper 
Patient Voiding Diary the patient will check Yes in response to the question “Did you record 
each time you urinated or leaked during this diary day?”  
If a subject completes more than the required 7 days of entry in the Diary, only “Complete” 
Diary Days within 10 days prior to the current visit are used to calculate eligibility.   
To be eligible for the study, patients must have a minimum of: 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018 
 
Confidential 
Page | 62 
 
 5 Complete Diary Days (not necessarily consecutive) during the Screening Period 
(over the 7 days prior to the Run-in Visit), and  
 4 Complete Diary Days (not necessarily consecutive) during the Run-in Period (over 
the 7 days prior to the Baseline Visit), and  
 be capable in the Investigator’s opinion of maintaining compliance with the diary 
requirements, including the measurement and recording of urine volume, as required, 
at Baseline and throughout the course of the study.  
To meet eligibility, patients must meet either the OAB Wet or OAB Dry criteria at the Run-in 
Visit and then the Baseline Visit, based on their Patient Voiding Diary data.  Patients will be 
randomized to the appropriate stratum based on which criteria are met at the Baseline Visit.  
When both components are present, the classification is specified as the predominant component. 
7.10.1. 
Patient Voiding Diary Training/Re-Training 
All Visits 
The site staff should inquire whether patients had any difficulties with the diary and address any 
questions patients may have. 
Instructions for proper completion of the Patient Voiding Diary should be re-reviewed, and, if 
available, patients may view an instructional video to reinforce their understanding of Patient 
Voiding Diary instructions. 
Patients 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 (e.g., upon getting up for the day). 
Run-in and Baseline Visits 
Responses to the Patient Voiding Diary will be reviewed by the site staff to assess whether 
patients are capable of completing the diary and if patients meet eligibility criteria.  The daily 
averages for micturitions, urgency episodes, and UUI episodes will be calculated as average of 
the total by the number of events on Complete Diary Days.  Patients who do not meet the OAB 
entry criteria will be excluded from the study. 
7.11. 
Urine Volume Diary 
Urine volume data are collected separately by patients using the Urine Volume component of the 
eDiary, or the paper Urine Volume Chart.  The Urine Volume Chart is a tool routinely used in 
clinical practice and clinical investigation to assess voiding functions over a 24-hour period and 
is regarded as a useful instrument in the investigation of patients with voiding symptoms. Urine 
volume may be collected during any one (1) of the 7 Diary Days prior to the visit, and it should 
be recorded for ~24-hours starting from the time the patient gets up for the day and continues 
until the time the patient gets up for the day on the next day.   
Patients will be asked to complete the Urine Volume Diary to record their urine volume passed 
during that day. The Urine Volume collection and Urine Volume Diary completion should be 
performed by the patient on a day that they choose for one (1) complete day of the 7 days prior to 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018 
 
Confidential 
Page | 63 
 
the Run-in Visit, Baseline Visit, and Week 2 (Diary only; no cinic visit), and the Weeks 4, 8, and 
12 Visits. The definition of a Diary Day and data entry instructions will be the same as for the 
Patient Voiding Diary (i.e., the data should be recorded in real time, morning to morning). 
7.11.1. 
Urine Volume Collection Training/Re-Training 
At the Screening Visit, all patients will receive detailed instructions on urine volume collection 
and measurement and/or be provided and review instructions with site staff.  The site staff should 
demonstrate how to measure a volume of water in a sample collection supplies before asking 
patients to demonstrate their ability to measure a volume of water as practice.  At each 
subsequent visit the site staff should confirm the patient’s understanding and ability to measure a 
volume of water as practice. 
Patients should be instructed that on the days the paper Urine Volume Chart Diary is completed: 
 Every micturition recorded on the Patient Voiding Diary must have a corresponding 
entry recorded on the Urine Volume Chart (this is automatically done on the eDiary). 
 Every entry recorded on the Urine Volume Chart must have a corresponding 
micturition recorded on the Patient Voiding Diary (this is automatically done on the 
eDiary). 
Site staff should reinstruct the patient on Urine Volume collection procedures as needed. 
Instructions for proper completion of the Urine Volume Chart should be re-reviewed, and, if 
available, patients may view an instructional video to reinforce their understanding of the Urine 
Volume Chart and collection instructions. 
7.11.2. 
Dispense Urine Collection and Measurement Supplies 
The urine collection and measurement container (if needed) are reusable and should be rinsed by 
patients and reused for the days that they will be collecting their urine volume throughout the 
study.  Patients should be reminded to keep the urine collection container with them during the 
period of time when urine volume is being collected. 
7.12. 
Reminders for Diary Collection 
The site will phone the patient on approximately the first day and the third (or next business 
days) of the 7 Diary collection days. Patients will be reminded to enter data immediately 
following each micturition (in real time); they will also be asked to input data from any “missed” 
events and confirm that data from all micturitions occurring within the preceding 24 hours have 
been entered at a consistent time each morning (e.g., upon getting up for the day). Patients 
participating in the PK subset will be reminded to withhold Study Treatment on the morning of 
the study visit for PK sampling (patients in population PK subset only). 
Patients may consent to receive additional reminders via SMS text to their personal mobile 
phone. In addition to visit reminders, these diary completion reminders will be sent the day 
before each diary collection period begins (to remind patients to start diary completion) and two 
days prior to the end of each diary collect window (to ensure urine volume collection has been 
completed prior to the visit).

7.13. 
Electronic Diary 
The Electronic Diary (eDiary) for this study includes both the Patient Voiding Diary, and the 
Urine Volume Diary, and will be implemented via an eDiary device (provisioned smartphone).  
Paper diaries will be provided to all patients to be used when necessary.  When a paper diary is 
used, it should be collected at each visit.  
7.13.1. 
eDiary Device Set-Up and Training 
Device Setup/Function Check 
The eDiary device will be set-up by the site at the Screening Visit and dispensed to the Patient.  
At each subsequent visit, site personnel will check that the device is functioning correctly.  
Instructions on how to perform the set-up task will be provided by the Sponsor. 
7.13.2. 
Device Training/Re-Training 
Prior to study initiation, site staff will be trained on how to instruct patients on the use of the 
eDiary.  Training materials for site staff, including general instructions and specific questions 
relating to completion of the eDiary, will be provided to each site and should be used as a guide 
on how to instruct patients. 
At the Screening Visit, site staff will carefully explain the collection of the Patient Voiding Diary 
and Urine Volume Diary on the eDiary device to patients and will clearly demonstrate how to 
record the occurrence of urinating in the toilet (micturition), episodes of needing to urinate 
immediately (urgency), and episodes of accidental urine leakage (incontinence) along with the 
main reason for leakage.  Site staff will answer any questions that patients may have and will 
instruct patients to call the site with any questions they may have about the eDiary after they 
have left the clinic.  Patients will complete the eDiary for several example situations prior to 
taking the eDiary home. 
At subsequent visits, patients will be reinstructed as needed. Instructions for proper completion 
of the eDiary should be re-reviewed, and, if available, patients may view an instructional video 
to reinforce their understanding. 
7.14. 
Patient-Reported Outcomes 
Patients will complete paper questionnaires at the site at the start of each required study visit to 
assess patient-perceived symptom relief, symptom bother, and health-related quality of life at the 
study visits.  These include the following questionnaires: 
 Global Impression Items include Patient Global Impression of Severity 
(PGI-Severity), Patient Global Impression of Control (PGI-Control), Patient Global 
Impression of Frequency (PGI-Frequency), Patient Global Impression of Leakage 
(PGI-Leakage), and Patient Global Impression of Change (PGI-Change). 
 Overactive Bladder Questionnaire (OAB-q long form 
-q L
, 1-week recall) 
is a multi-item questionnaire that was developed to assess symptom bother and the 
impact of overactive bladder on health-related quality of life.  The instrument was 
developed and validated in both continent and incontinent OAB patients, including 
both men and women.

 Work Productivity and Activity Impairment Questionnaire-Urinary Symptoms 
(WPAI-US), version 2.0, is a 6-item questionnaire that assesses health-related work 
productivity loss due to urinary symptoms with a 1-week recall period. 
 The EQ-5D health questionnaire is a standardized instrument for use as a measure of 
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. 
The Investigator should not provide any additional information to patients prior to completing 
the questionnaires which might influence responses. 
7.15. 
Post-Void Residual Volume 
The risk of acute urinary retention or morbidities related to an increase in Post-Void Residual 
(PVR) is a concern with antimuscarinic therapy that promotes smooth muscle relaxation by 
inhibiting acetylcholine-induced smooth muscle contraction.  If, during contraction, the bladder 
cannot generate enough pressure to overcome the outlet resistance in the urethra, either because 
of poor detrusor contractility or profound obstruction (most commonly from BPH), acute urinary 
retention or incomplete emptying of the bladder may result. 
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 patients with 
an increase in PVR for an adverse event. 
PVR will be performed via ultrasound at the visits indicated in the Schedule of Activities 
(Table 1).  All efforts will be made to ensure the same device and operator are used for all PVR 
volume measurements for individual patients. 
7.16. 
Physical Examination 
Complete physical examinations will include a digital rectal examination for men at the 
Screening Visit to confirm entry criteria. 
Focused physical examinations will be performed at the Run-in and Follow-up Visit and will 
include examination of heart, lungs, abdomen, and pelvic exam (only as needed to confirm 
prolapse), as well as any other organ system in which a previous abnormality was noted at 
Baseline or relates to a patient complaint of an adverse event. 
7.17. 
Electrocardiogram 
A single twelve-lead ECG will be performed at the Screening Visit and may be performed, as 
clinically indicated, at an Unscheduled Visit. 
ECG should be performed after 10 minutes of rest in a semi-recumbent position. 
7.18. 
Vital Signs 
Vital signs including blood pressure, heart rate, respiration rate, and temperature (oral or 
tympanic) will be obtained at all visits after patients have rested quietly in a sitting position for 
5 minutes.

Three blood pressure measurements will be taken in a sitting position and performed on the same 
arm and by the same site staff, if possible, for each patient throughout the study.  The following 
instructions should be followed: 
 Sitting systolic and diastolic blood pressures will be determined by averaging 
3 replicate measurements obtained 1 to 2 minutes apart.  The average of the 
3 replicate blood pressure measurements will be used for eligibility and safety 
assessments (not an individual value). 
The same method for assessing temperature should be used at all visits for a particular patient. 
Body weight will be measured with patients in street clothing with jacket/coat and shoes 
removed. 
Standing height will be measured without shoes at Screening only. 
7.19. 
Adverse Events 
Spontaneously reported adverse events will be recorded at each visit.  The Investigator or site 
staff is responsible for detecting, documenting, and reporting events that meet the definition of 
an adverse event or serious adverse event.  See Section 8 for details on adverse event definitions 
and reporting. 
7.20. 
Clinical Laboratory Assessments 
Details regarding specific laboratory procedures/assessments to be performed in this study are 
provided below.  The total amount of blood/tissue to be drawn/collected over the course of the 
study (from pre-study to post-study visits), including approximate blood/tissue volumes 
drawn/collected by visit and by sample type per patient can be found in Appendix C. 
Please refer to the Schedule of Activities (Table 1) for specific laboratory tests performed at each 
study visit. 
7.20.1. 
Chemistry, Hematology, and Urinalysis (Laboratory Safety Evaluations) 
Laboratory tests for chemistry, hematology, and urinalysis are specified in Table 5.  Patients do 
not need to fast prior to laboratory safety tests. 
Analysis of hematology and chemistry will be performed by the central laboratory chosen by the 
Sponsor.  A urine dipstick and urine pregnancy test (for women of childbearing potential) will be 
performed at the site (supplied by the central laboratory).  A sample for urinalysis (including 
e 
central laboratory only if the urine dipstick tests positive for the presence of leukocytes, nitrites, 
or blood cells.  If a patient reports symptoms that are suggestive of a uriary tract infection at any 
visit, a urine dipstick should be performed and a sample sent for urinalysis and culture, as 
needed. 
If all laboratory values are within the normal reference range, the patient may continue to be 
evaluated for study entry.  If one or more values fall outside the normal range, the Investigator 
may either exclude the patient from the study or investigate further to determine clinical

A unique 
 patient number will be allocated to each subject during the Screening Visit 
using the IxRS.  The identifier will consist of 
 
.  The patient number identifies the patient for all procedures occurring 
after screening.  Once a patient number is assigned to a patient, it can never be re-assigned to 
another patient. 
At the Baseline Visit, all eligible patients will be randomly allocated to double-blind Study 
Treatment using IxRS. 
7.23. 
Dispense Double-Blind Study Treatment 
At the Baseline, Week 4, and Week 8 Visits, double-blind Study Treatment will be dispensed to 
patients, as described in Section 6, and according to their randomized treatment assigned per 
IxRS. 
7.24. 
Study Treatment Return/Accountability Review 
Patients should bring all unused study drug to each study visit.  A complete tablet/capsule count 
will be performed, and results will be recorded as the primary source of patient Study Treatment 
compliance.  Tablet/capsule counts will also be recorded in the IxRS.  All patients should be 
reinstructed regarding dosing compliance during study visits.  The authorized study personnel 
conducting the re-education must document the process in the patient’s source records.

Pharmacokinetic (PK) Sampling (PK Subset Only) 
7.26.1. 
Pharmacokinetic Sample Collection 
PK sampling will be conducted in a sub-population of patients (approximately 30% of the total 
study population) at selected sites for assessment of the effect of demographic covariates by 
population PK analysis.  The patient must consent to participate in PK sampling. 
PK samples should be collected during the clinic visit after all other study assessments have been 
completed. 
Pre-dose PK samples will be collected at three visits:  Week 4, Week 8, and Week 12.  The time 
of last dose of study medication (taken the day prior to the visit) should be recorded. 
Details regarding the collection procedure, handling, storage, and shipment of these samples will 
be provided by the central laboratory. 
Continuation into Extension Study 
Patients who complete the Week 12 Visit may be offered the opportunity to enroll in a 40-week 
double-blind extension study (RVT-901-3004), which will be conducted under a separate 
protocol, until enrollment in that study is complete. 
Participation in the extension study is separate from this study and is optional.  Patients will 
provide separate informed consent to participate in the extension study. 
7.27. 
Follow-up Visit 
For patients who do not enroll in the optional extension study (RVT-901-3004), the Follow-up 
Visit should be performed 28 days after the patient’s last dose of Study Treatment to collect 
information about any serious adverse events that occurred during this period.  For a patient who 
discontinues Study Treatment early, the Follow-up Visit should occur 28 days after the last dose 
of Study Treatment.  
28 days after the patient’s 
last dose of Study Treatment, that visit will serve as the Follow-up Visit.  Safety labs may be 
collected for the evaluation of adverse experiences during discontinuation at the discretion of the 
Investigator.

8. 
SAFETY CONSIDERATIONS 
Study assessments of safety include adverse events, physical examinations, vital signs (and 
weight), and clinical laboratory tests. 
8.1. 
Definition of an Adverse Event 
An adverse event is any untoward medical occurrence in a patient or clinical investigation 
patient, temporally associated with the use of a medicinal product, whether or not considered 
related to the medicinal product. 
An adverse event can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use 
of a medicinal product or protocol-specified procedure, whether or not considered related to the 
medicinal product or protocol-specified procedure.  Any worsening (i.e., any clinically 
significant adverse change in frequency and/or intensity) of a preexisting condition that is 
temporally associated with the use of the Sponsor’s product, is also an adverse event. 
Events meeting the definition of an adverse event include: 
 A worsening, excluding minor fluctuations, in the nature, severity, frequency, or 
duration of a pre-existing condition; 
 A new condition detected or diagnosed after investigational product administration 
even though it may have been present prior to the start of the study; 
 Injury or accidents:  If a medical condition is known to have caused the injury or 
accident, the medical condition and the accident should be reported as 2 separate 
medical events (e.g., for a fall secondary to dizziness, both “dizziness” and “fall” 
should be recorded separately); 
 An investigational abnormality (e.g., laboratory parameter, vital sign, ECG) only if 
the abnormality is considered clinically significant by the Investigator based on at 
least one of the following criteria: 
 Induces clinical signs or symptoms; 
 Requires active intervention; 
 Requires interruption or discontinuation of Study Treatment. 
 Signs, symptoms, or the clinical sequelae of a suspected interaction. 
 Signs, symptoms, or the clinical sequelae of a suspected overdose of either 
investigational product or a concomitant medication. 
 Events that do not meet the definition of an adverse event include: 
 The disease/disorder being studied, or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the patient’s 
condition; 
 Medical or surgical procedure (e.g., endoscopy, appendectomy) should be entered 
into the eCRF.  If not planned prior to signing the informed consent, the condition 
that leads to the procedure is reported as an adverse or serious event, as appropriate.  

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018 
 
Confidential 
Page | 71 
 
Periodic procedures for routine maintenance of a medical device should not be 
considered associated with an adverse event (e.g., expected change of a stent); 
 Situations where an untoward medical occurrence did not occur (e.g., planned 
hospitalization for an elective procedure, with elective defined as known or planned 
at the time of signing of the informed consent; social and/or convenience admission 
to a hospital); 
 Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen. 
Adverse events that occur during the study should be evaluated by the Investigator and assessed 
for causal relationship to Study Treatment and severity, as described in Section 8.4 and 
Section 8.5.  Episodic adverse events, such as vomiting, or those that occur repeatedly over a 
period of consecutive days are “intermittent”.  All other events are “continuous”.  Additional 
information on detecting, documenting, and reporting adverse events and serious adverse events 
are provided below.  No toxicity-related dose reductions of Study Treatment are permitted; 
however, Study Treatment can be held for a period of up to 21 days for evaluation and treatment 
of an adverse event.  The Study Treatment may be restarted if deemed safe for the patient by the 
Investigator. 
8.2. 
Definition of a Serious Adverse Event 
If an event is not an adverse event per Section 8.1, then it cannot be a serious adverse event if 
serious conditions are met (e.g., hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease, etc.).  A serious adverse event is any untoward medical 
occurrence that, at any dose: 
a. Results in death 
b. Is life-threatening 
NOTE:  The term 'life-threatening' in the definition of 'serious' refers to an event in 
which the patient was at risk of death at the time of the event.  It does not refer to an 
event, which hypothetically might have caused death, if it were more severe. 
c. Requires hospitalization or prolongation of existing hospitalization 
NOTE:  In general, hospitalization signifies that the patient has been detained 
(usually involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the physician’s 
office or out-patient setting.  Complications that occur during hospitalization are 
adverse events.  If a complication prolongs hospitalization or fulfills any other serious 
criteria, the event is serious.  When in doubt as to whether “hospitalization” occurred 
or was necessary, the adverse event should be considered serious. 
Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE. 
d. Results in disability/incapacity 
NOTE:  The term disability means a substantial disruption of a person’s ability to 
conduct normal life functions.  This definition is not intended to include experiences 
of relatively minor medical significance such as uncomplicated headache, nausea, 
vomiting, diarrhea, influenza, and accidental trauma (e.g., sprained ankle) which may 

Clinical Study Protocol

Page | 72 
 
interfere or prevent everyday life functions but do not constitute a substantial 
disruption. 
e. Is a congenital anomaly/birth defect 
f. Medical or scientific judgment should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize 
the patient or may require medical or surgical intervention to prevent one of the other 
outcomes listed in the above definition.  These should also be considered serious.  
Examples of such events are invasive or malignant cancers, intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse. 
8.3. 
Adverse Event Reporting 
The Investigator or site staff is responsible for detecting, documenting, and reporting events that 
meet the definition of an adverse event or serious adverse event. 
The reporting of serious adverse events by the sponsor (Urovant Sciences GmbH) to regulatory 
authorities is a requirement and each authority has a timetable for reporting these events based 
upon established criteria.  Likewise, it is the responsibility of the Investigator to report serious 
adverse events to their local IRB, REB, or IEC, as required by their local IRB/REB/IEC 
requirements. 
Care will be taken not to introduce bias when detecting adverse events and/or serious adverse 
events.  Open-ended and non-leading verbal questioning of the patient is the preferred method to 
inquire about adverse event occurrence.  Appropriate questions include: 
 “How are you feeling?” 
 “Have you had any (other) medical problems since your last visit/contact?” 
 “Have you taken any new medicines, other than those provided in this study, since 
your last visit/contact? 
The patient’s eDiary entries and responses to questionnaires used in the study will not be used as 
a primary means to collect adverse events however, they should be reviewed by the study site 
personnel and the study monitors.  Should the Investigator or site staff become aware of a 
potential adverse event through the information collected with these instruments, proper follow-
up with the patient for medical evaluation should be undertaken.  Through this follow-up, if it is 
determined that an adverse event not previously reported has been identified, normal reporting 
requirements should be applied. 
All patients who experience an adverse event will be evaluated at appropriate time intervals and 
followed until the event resolves, becomes stable or chronic, or the patient is deemed lost to 
follow-up.  At the conclusion of the study, the Investigator and medical monitor will assess 
unresolved adverse events and determine if additional/continued follow-up is warranted. 
All adverse events, whether related to the Study Treatment or not, must be fully and completely 
documented on the adverse event case report form and in the patient’s source documents.  In 
addition, any adverse event resulting in permanent treatment discontinuation must be recorded 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018 
 
Confidential 
Page | 73 
 
on the appropriate case report form as well as documented in the patient’s source documents.  
Adverse event terms should include a diagnosis, as available, in preference to listing the 
individual signs and symptoms.  If the diagnosis is not known, the Investigator should record 
each sign and symptom as an individual adverse event. 
Reporting for overdose and for pregnancy in the patient or patient’s partner will be reported as 
described in Section 8.3.3 and Section 8.7, respectively. 
8.3.1. 
Period for Reporting Adverse Events 
Adverse events and serious adverse events will be collected from the time a patient provides 
informed consent to participate in the study until the Follow-up Visit is completed approximately 
28 days after the last dose of Study Treatment or the date of initiation of another investigational 
agent, an alternate therapeutic drug for overactive bladder, or surgical intervention for overactive 
bladder, whichever occurs first.  Serious adverse events reported to the Investigator after the 
safety reporting period should be reported to the sponsor if the Investigator assesses the event as 
related to the Study Treatment. 
Reporting instructions for serious adverse events are provided in Section 8.3.2. 
8.3.2. 
Reporting Serious Adverse Events 
All serious adverse events must be reported in the eCRF within 24 hours of the study site 
personnel’s knowledge of the event, regardless of the Investigator assessment of the 
relationship of the event to Study Treatment. 
The event term, start date, severity, and initial causality assessment must be entered in the 
Adverse Event eCRF page and the event must be marked as “Serious”.  This will activate 
additional assessment fields including “action taken with study drug”, “seriousness criteria”, and 
“brief description” which should be completed as soon as information is available.  Marking the 
event as “serious” will automatically send required notifications for Sponsor review. 
The initial serious adverse event report should include: 
 The date of the report; 
 A description of the serious adverse event (event term, seriousness of the event, date 
of onset, intensity); and 
 Causal relationship to the Study Treatment. 
A discharge summary should be provided for all hospitalizations.  If the patient died, the report 
should include the cause of death as the event term (with death as the outcome) and whether the 
event leading to death was related to Study Treatment, as well as the autopsy findings, if 
available. 
Do not delay reporting a suspected serious adverse event to obtain additional information.  Any 
additional information, if collected, can be reported as a follow-up to the initial report. 
All patients who experience a serious adverse event will be evaluated at appropriate time 
intervals and followed until the event resolves, becomes stable or chronic, or the patient is 
deemed lost to follow-up.  Serious adverse events reported to the Investigator after the safety 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018 
 
Confidential 
Page | 74 
 
reporting period should be reported to the sponsor if the Investigator assesses the event as related 
to the Study Treatment. 
8.3.3. 
Study Treatment Overdose Management 
The medical monitor must be contacted in the event of any Study Treatment overdose. 
An overdose is defined as a known deliberate or accidental administration of Study Treatment, to 
or by a study patient, at a dose above that assigned to that individual patient according to the 
study protocol. 
For this study, any dose of vibegron or placebo > 2 tablets and any dose of tolterodine or placebo 
> 2 capsules within a 24-hour window (i.e., > 2 tablets and/or > 2 capsules of blinded Study 
Treatment within a 24-hour window) is an overdose.  There is no known antidote for an 
overdose. 
In the event of an overdose, the Investigator or treating physician should: 
 Contact the medical monitor immediately; 
 Closely monitor the patient for adverse events and laboratory abnormalities; 
 Report all overdose events within 24 hours of awareness by the study site, using a 
serious adverse event form according to Section 8.3.2, whether or not the overdose is 
associated with an adverse event; 
 If possible, obtain a plasma sample for PK analysis within 2 days from the date of the 
last dose of Study Treatment if requested by the medical monitor (determined on a 
case-by-case basis); 
 Document the quantity of the excess dose as well as the duration of the overdosing in 
the eCRF. 
The medical monitor, in consultation with the Investigator, will make decisions regarding patient 
status and potential dose interruptions, based on the clinical evaluation of the patient. 
8.4. 
Assigning Causal Relationship to Study Treatment 
The reasonable possibility of the relationship of an adverse event to Study Treatment is to be 
assessed with careful medical consideration at the time of evaluation of an adverse event.  The 
following definitions are to be used for the relationship of the adverse event to Study Treatment: 
 Probably related:  A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to administration of the drug, unlikely attributed to 
concurrent disease or other drugs or chemicals, or that follows a clinically reasonable 
response on re-administration (rechallenge) or withdrawal (dechallenge). 
 Possibly related:  A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to administration of the drug but that could also be 
explained by concurrent disease or other drugs or chemicals.  Information on drug 
withdrawal may be lacking or unclear. 
 Not related:  A clinical event, including laboratory test abnormality, with a temporal 
relationship to drug administration that makes a causal relationship improbable and/or 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH 
Effective:  15 NOV 2018 
 
Confidential 
Page | 75 
 
in which other drugs, chemicals, or underlying disease provide a plausible 
explanation. 
All adverse events, whether related to Study Treatment or not, must be fully and completely 
documented on the adverse event page of the eCRF and in the patient’s clinical record.  In the 
event a patient is withdrawn from the study because of an adverse event, the primary reason for 
withdrawal (i.e., due to an adverse event) must be recorded on the eCRF as such. 
8.5. 
Assigning Severity Rating for Adverse Events 
Severity describes the intensity of a specific event (as in mild, moderate, or severe myocardial 
infarction); the event itself, however, may be of relatively minor medical significance, such as a 
severe headache.  This is not the same as “serious,” which is based on patient/event outcome or 
action taken. 
The Investigator must determine the severity of each adverse event according to the criteria in 
Table 6. 
Table 6 
Criteria for Determining the Grade/Severity of Adverse Event Terms 
Grade 
Criteria 
1/Mild 
Asymptomatic or mild symptoms, clinical or diagnostic 
observations only; intervention not indicated 
2/Moderate 
Minimal, local, or noninvasive intervention indicated; limiting 
age-appropriate instrumental activities of daily living 
3/Severe or medically 
significant 
Not immediately life-threatening; hospitalization or prolongation 
of hospitalization indicated; disabling; limiting self-care 
activities of daily living 
4/Life-threatening

Adverse Events of Clinical Interest for this study include: 
 
Potential Major Adverse Cardiac and Cerebrovascular Events (MACCE), which will be 
adjudicated by an independent external expert clinical adjudication committee (CAC) 
into the following categories according to the definitions in the CAC Charter: 
 
Death or any event with fatal outcome 
 
Myocardial infarction / Heart Attack 
 
Cerebrovascular Accident / Stroke 
 
Hospitalization for Unstable Angina / Chest Pain 
 
Hospitalization for Heart Failure 
 
Coronary revascularization / Angioplasty / Stent 
 
Hypertension: 
An adverse event of hypertension should be reported and will be an AECI as follows: 
 
For patients without hypertension (average SBP <140 mmHg, DBP <90 mmHg) 
at baseline, at two consecutive visits, the average of three systolic blood 
pressure (SBP) 
 mmHg or diastolic blood pressure (DBP) 
 mmHg (or 
both); at 2 consecutive visits in patients who were not hypertensive at baseline; 
or, 
 
For patients with hypertension at baseline, an increase compared to baseline at 
2 consecutive visits in the average of three SBP by 
 mmHg OR DBP 
by 
 mmHg;  
 
Initiation of, or increase in dose of, medication for treatment of hypertension in 
any patient. 
 
Adverse events consistent with orthostatic hypotension as confirmed by orthostatic vital 
signs. 
 
Adverse events suggestive of cystitis or urinary tract infection. 
 
Elevated AST or ALT lab value requiring that study drug be temporarily withheld or 
permanently discontinued (see Section 8.6.1 and Section 8.6.2). 
Note:  These criteria are based upon available regulatory guidance documents.  The purpose of 
the criteria is to specify a threshold of abnormal hepatic tests that may require an additional 
evaluation for an underlying etiology.  Study site guidance for assessment and follow up of these 
criteria can be found in the Study Reference Manual. 
8.6.1. 
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 AECI 
specific eCRFs/forms/worksheets provided for the study. 
Hepatic enzymes will be monitored in accordance with FDA drug-induced liver injury guidelines

If the following liver test abnormalities develop, Study Treatment should be withheld 
immediately with appropriate clinical follow-up (including repeat laboratory tests, until a 
patient’s laboratory profile has returned to normal/baseline status), and the event reported as a 
serious adverse event: 
 ALT or AST > 8 x ULN; or 
 ALT or AST > 5 x ULN and persists for more than 2 weeks; or 
 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 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. 
8.6.2. 
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 (i.e., 
potential severe drug-induced liver injury/Hy’s law case): 
1. Total bilirubin increases to > 2 x ULN or INR > 1.5; AND 
2. 
3 x ULN; AND 
3. Alkaline phosphatase value does not reach 2 x ULN; AND 
4. 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 (e.g., 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; or 
 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 Treatment should be withheld or 
permanently discontinued as appropriate for the safety of the patient.

8.7. 
Pregnancy Management and Reporting to the Sponsor 
If any patient or female partner of a patient becomes pregnant during the study, the site must 
discontinue the patient from Study Treatment immediately and have the patient return for an 
Early Withdrawal Visit (Week 12 Visit activities).  The Investigator must inform the patient of 
their right to receive treatment information.  If the patient chooses to receive unblinded treatment 
information, the individual blind should be broken and the treatment assignment provided to the 
patient.  The study team will remain blinded to the patient’s treatment assignment. 
In the case of a pregnant patient, if she agrees, the Investigator should notify the patient’s 
primary care physician of the pregnancy and provide details of the patient’s participation in the 
study and treatment (blinded or unblinded, as applicable). 
In the case of a male patient with a pregnant partner, if the patient agrees, the patient’s pregnant 
partner should be notified and requested to sign a Release of Information form, permitting 
transfer of information regarding the pregnancy and outcome to the sponsor. 
A pregnancy is to be reported to the sponsor within 24 hours of awareness by the study site 
personnel, using the pregnancy reporting forms and the contact information in Section 8.3.2.  
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. 
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. 
8.8. 
Benefit/Risk Assessment 
Patients may not expect to receive direct benefit from treatment during participation, as this 
study is designed to provide information about the safety and effectiveness of an investigational 
medicine compared to placebo.  Some patients will receive tolterodine, an approved medication 
for treating overactive bladder with symptoms of urinary frequency, urgency, and leakage.

9.3. 
Analysis Endpoints 
Efficacy, safety, and exploratory endpoints that will be evaluated for within- and/or between-
treatment differences are listed below.  The descriptions of the endpoints and time points at 
which they are measured are described in Section 3 and Table 1 (Schedule of Activities), 
respectively. 
No formal comparisons of vibegron vs. tolterodine are planned; all between-treatment analyses 
between these two groups will be considered descriptive. 
9.3.1. 
Efficacy Endpoints 
In describing the efficacy variables of interest below, the descriptions are restricted to the 
primary time point of interest at Week 12 in the study.  However, many variables are measured 
at additional time points, as indicated in the Schedule of Activities, and will be analyzed at other 
time points. 
Co-Primary Efficacy Endpoints: 
 Change from baseline (CFB) at Week 12 in average number of micturitions per 
24 hours in all OAB patients 
 CFB at Week 12 in average number of UUI episodes per 24 hours in OAB 
Wet patients 
For the purpose of this study, the number of micturitions will be defined as the number of times a 
patient has voided in the toilet as indicated on the Patient Voiding Diary.  Average daily 
micturitions are calculated using the daily entries in the Patient Voiding Diary, which is 
completed over the 7 days prior to each study visit.  Average daily number of micturitions will 
be calculated as the total number of micturitions that occur on a Complete Diary Day divided by 
the number of Complete Diary Days in the Patient Voiding Diary.  A complete diary day 
requires confirmation by the patient in the Patient Voiding Diary that all voids and leakages have 
been recorded for the diary day.  Baseline is defined as the average number of micturitions 
occurring during the last evaluable diary prior to the Baseline Visit. 
The number of UUI episodes will be defined as the number of times a patient has checked "urge" 
as the reason for accidental urine leakage.  Average daily UUI episodes at each study visit will 
be calculated in the same manner as described above for the micturition endpoint.  The UUI 
endpoint will be analyzed using only OAB Wet patients. 
Key Secondary Efficacy Endpoints: 
 CFB at Week 12 in average number of urgency episodes (need to urinate 
immediately) over 24 hours in all OAB patients 
 Percent of OAB Wet patients with at least a 75% reduction from baseline in UUI 
episodes per 24 hours at Week 12 
 Percent of OAB Wet patients with a 100% reduction from baseline in UUI episodes 
per 24 hours at Week 12 
 Percent of all OAB patients with at least a 50% reduction from baseline in urgency 
episodes (need to urinate immediately) per 24 hours at Week 12

9.3.2. 
Safety Endpoints 
Safety and tolerability will be assessed via clinical review of all relevant safety parameters 
including clinical adverse events, clinical laboratories, vital signs, and physical examinations that 
occurred during the respective study period. 
9.4. 
Analysis Populations 
9.4.1. 
Efficacy Analysis Populations 
The Full Analysis Set (FAS) population will serve as the primary population for the analysis of 
efficacy data in this study.  Since the endpoints related to incontinence would only apply to 
patients who meet the definition of incontinence at study entry, it is necessary to have a separate 
FAS definition with an additional criterion to define the primary analysis population for 
incontinence endpoints. 
The following FAS populations are defined in the study: 
 Full analysis set (FAS):  all randomized OAB patients who took at least one dose of 
double-blind Study Treatment and have at least one evaluable change from baseline 
micturition measurement 
 Full analysis set for incontinence (FAS-I):  all randomized OAB Wet patients who 
took at least one dose of double-blind Study Treatment and have at least one 
evaluable change from baseline UUI measurement 
The Per-Protocol population (PP) and Per-Protocol population for incontinence (PP-I) exclude 
patients due to important deviations from the protocol that may substantially affect the results of

the primary efficacy endpoints.  A supportive analysis using the Per-Protocol populations will be 
performed for the co-primary and key secondary efficacy endpoints.  The final determination on 
protocol violations, and thereby the composition of the Per-Protocol population, will be made 
prior to the unblinding of the database and will be documented in a separate memo. 
Patients will be included in the treatment group to which they are randomized for the analysis of 
efficacy data using the FAS and Per-Protocol populations. 
9.4.2. 
Safety Analysis Populations 
The Safety Set (SAF) will be used for the analysis of safety data in this study.  The SAF consists 
of all patients who received at least one dose of Study Treatment.  Patients will be included in 
the treatment group corresponding to the Study Treatment they actually received for the analysis 
of safety data using the SAF population.  For most patients this will be the treatment group to 
which they are randomized. 
At least one laboratory or vital sign measurement obtained subsequent to at least one dose of 
Study Treatment is required for inclusion in the analysis of each specific parameter.  To assess 
change from baseline, a Baseline measurement is also required. 
No imputation will be performed for missing safety data.  Baseline will be defined as the last 
non-missing value before treatment. 
9.4.3. 
Pharmacokinetic Population 
The PK population will include all subjects in the Safety Set who undergo plasma PK sampling 
and have evaluable PK assay results. 
9.5. 
Statistical Methods 
Statistical testing and inference methods for safety and efficacy analyses are described below.  
Efficacy results that will be considered statistically significant after consideration of the strategy 
for controlling the Type I error are described in Section 9.6, Multiplicity.  Nominal p-values may 
be computed for other efficacy analyses as a measure of the strength of association between the 
endpoint and the treatment effect rather than formal tests of hypotheses.  Unless otherwise stated,

9.5.1. 
Statistical Methods for Efficacy Analyses 
9.5.1.1. 
Primary Efficacy Endpoints 
For the analysis of the co-primary endpoints (change from baseline in average number of daily 
micturitions at Week 12 and change from baseline in average number of daily urge urinary 
incontinence episodes at Week 12), 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 patient over time tend to be correlated 
by using all available information on patients 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 treatment, visit, OAB Type (Wet vs Dry), Sex (Female vs Male), 
Region (US vs Rest of World), baseline score, and interaction of visit by treatment.

Page | 85 
 
Primary inferences will be drawn from treatment differences for the changes from baseline 
derived from the MMRM models at Week 12.  As part of secondary objectives, the treatment 
differences for each post baseline visit will also be derived using the same MMRM model.  The 
estimated treatment difference for at each visit will be displayed in the summary of statistical 
analysis together with the 95% confidence interval and the associated p-value. 
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.  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. 
9.5.1.2. 
Sensitivity Analyses 
9.5.1.3. 
Secondary Efficacy Endpoints 
The change from baseline efficacy endpoints will be analyzed using the same MMRM model 
described for co-primary endpoints. 
Analysis of the efficacy endpoints of proportion of patients with at least 75% reduction or a 
100% reduction in the average number of daily UUI episodes at Week 12 and proportion of 
patients with at least 50% reduction in the average number of daily urgency episodes at 
Week 12 will be analyzed using the Cochran-Mantel-Haenszel risk difference estimate.  Missing 
Week 12 data will be analyzed using multiple imputation.  The estimated difference in the 
proportion of responders and 95% confidence interval for the difference will be calculated using 
the Cochran-Mantel-Haenszel risk difference estimate stratified by OAB Type (Wet vs Dry) and 
Sex (Female vs Male), with weights proposed by Greenland and Robins.  Further details will be 
provided in the SAP.

Statistical Methods for Safety Analyses 
Safety analyses will be conducted using the SAF and summarized by treatment group as treated.  
The treatment-emergent period will be defined as the period of time from the first dose date of 
the double blinded Study Treatment through 28 days after the last dose of Study Treatment, or 
the date of initiation of another investigational agent or surgical intervention or rollover to the 
extension study, whichever occurs first.  Safety will be assessed through summaries of adverse 
events, the frequency of treatment discontinuations due to adverse events, and clinical laboratory 
evaluations. 
The severity of all adverse events will be evaluated by the Investigator as described in 
Section 8.5.  All adverse events will be coded to preferred term and system organ class using 
Medical Dictionary for Regulatory Activities (MedDRA) 20.0 or higher.  The incidence of 
adverse events will be presented by MedDRA 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 analyses. 
Vital signs parameters, including temperature, will be listed and summarized by visit. 
9.5.3. 
PK Analysis 
Plasma concentrations will be listed and summarized by study visit and treatment group. 
Pharmacokinetic parameters for RVT-901 for each subject may be estimated via nonlinear mixed 
effect modeling using a population PK model and described in a separate report. 
9.6. 
Multiplicity 
A stepwise gate-keeping procedure will be used to control the overall Type-I error rate at 
5 level (two-sided) over the co-primary and key secondary hypotheses.  If both co-primary 
endpoints are achieved, then the key secondary endpoints will be tested sequentially in the 
predefined order given in Section 9.2.  If statistical significance is achieved at all previous key 
secondary endpoints, the next sequential key secondary endpoint will be tested.  Once a key 
secondary endpoint is found to be insignificant (i.e. p-
stop.  For all subsequent key secondary endpoints, nominal p-values will be provided. 
All other efficacy endpoints will be considered supportive and no multiplicity adjustments will 
be performed for these other efficacy endpoints.  Nominal p-values will be computed for other 
efficacy endpoints as a measure of the strength of association between the endpoint and the 
treatment effect rather than formal tests of hypotheses.  Unless otherwise stated, all statistical 
tests will be conducted at the (two-
5 level of significance.

Sample Size Determination 
Approximately 1,400 patients will be randomized in a 5:5:4 ratio to receive one of the following 
Study Treatments: 
 Vibegron 75 mg + placebo to match tolterodine ER 4 mg; 
 Placebo to match vibegron 75 mg + placebo to match tolterodine ER 4 mg; or 
 Tolterodine ER 4 mg + placebo to match vibegron 75 mg 
Approximately 500 patients will be assigned to the vibegron and placebo treatment groups, and 
approximately 400 patients will be assigned to the tolterodine treatment group.  Assuming that a 
total of 10% patients will discontinue prior to Week 12 (for any reason), there will be 
approximately 450 evaluable patients in the vibegron and placebo treatment groups at the end of 
Week 12.  Assuming 75% of the population will have OAB Wet, there will be approximately 
337 evaluable patients in the vibegron and placebo treatment groups for the incontinence 
endpoints.  The study has: 
 Approximately 98% power to detect a true underlying between-group treatment 
difference of 0.6 in change from baseline in micturitions at a two-sided 0.05 level 
assuming a variability estimate of 2.20 based on vibegron Study 008 data. 
 Approximately 98% power to detect a true underlying between-group treatment 
difference of 0.51 in change from baseline in urge urinary incontinence at a two-sided 
0.05 level assuming a variability estimate of 1.68 based on vibegron Study 008 data. 
Assuming that these endpoints are uncorrelated, then this study has 96% power to reject both co-
primary hypotheses. 
9.8. 
Subgroup Analyses and Effect of Baseline Factors 
To determine whether the treatment effect is consistent across various subgroups, the estimate of 
the between-group treatment effect (with a nominal 95% confidence interval CI ) for the 
primary endpoint will be estimated and plotted within each category of the following 
classification variables: 
 Region (US vs. Rest of World) 
 Age category (< 
 40 to < 
 55 to < 
 65 to 75,  75 years) 
 Age category (< 65,  65 years) 
 Race (white vs. other) 
 Sex (female vs. male) 
 Prior OAB therapy (naïve vs. non-naïve) 
 OAB Type (OAB Wet vs. OAB Dry) 
For each subgroup, the primary MMRM model will be fit including a subgroup by treatment 
interaction term and model results will be presented.  The consistency of the treatment effect will 
be assessed descriptively via summary statistics by category for the classification variables listed 
above.

show equivalence to an effective product) or any study in which a single Investigator makes a 
significant contribution to the demonstration of safety.”  As such, all Investigators and Sub-
Investigators must provide documentation of their financial interest or arrangements with the 
Sponsor, or proprietary interests in the drug being studied.  This documentation must be provided 
before participation of the Investigator and any Sub-Investigator.  The Investigator and Sub-
Investigator agree to notify the Sponsor of any change in reportable interests during the study 
and for 1 year following completion of the study. 
10.2. 
Pre-Initiation Visit 
Sponsor personnel or designee(s) may visit the study site as necessary prior to initiation of the 
study to review information about the Study Treatment, protocol requirements, eCRFs, 
monitoring requirements, reporting of serious adverse events, and to ensure a full understanding 
of the Study Reference Manual with the site personnel. 
10.3. 
Data Management 
Patient data will be entered into a Sponsor-approved electronic database and combined with data 
provided from other sources in validated datasets then transmitted electronically to the Sponsor 
or designee. 
Management of clinical data will be performed in accordance with applicable Sponsor-approved 
standards and data cleaning procedures to ensure the integrity of the data (e.g., errors will be 
corrected and inconsistencies clarified). 
Adverse events and concomitant medications terms will be coded using the most current versions 
of the MedDRA (i.e., 20.0 or higher) and the World Health Organization Drug Dictionary 
Enhanced (WHO-DDE), respectively. 
The Investigator will retain original source documents and the Sponsor will receive eCRF-
required data as electronic datasets.  Patient initials will not be collected or transmitted to the 
Sponsor.

10.4. 
Monitoring 
This study will be monitored by the Sponsor (or designee) in accordance with current GCP 
regulations.  By signing this protocol, the Investigator grants permission to the Sponsor (or 
designee) and appropriate regulatory authorities to conduct on-site monitoring of all appropriate 
study documentation.  In order to verify the accuracy of data collected in the eCRF, the monitor 
will require direct access to original source documents (e.g., patient records, patient charts, and 
laboratory reports). 
During the review of these documents, the anonymity of the patient will be respected with strict 
adherence to professional standards of confidentiality.  A study monitor will contact and visit the 
site regularly and will be allowed, on request at a mutually acceptable time, to inspect the various 
records of the study.  It will be the study monitor’s responsibility to inspect the eCRF at regular 
intervals throughout the study, to verify the adherence to the protocol and the completeness, 
correctness, and accuracy of all eCRF entries, and to meet with the Investigator to discuss study 
progress and compliance with the protocol and GCP.  The study monitor should have access to 
laboratory test results and any other source records and data needed to verify the entries on the 
eCRF.  The Investigator agrees to cooperate with the study monitor to ensure that any problems 
detected in the course of these monitoring visits are resolved. 
10.5. 
Auditing or Inspections 
Representatives of regulatory authorities, health authorities, the Sponsor, or IRB/REB/IEC’s may 
conduct inspections or audits of the clinical study.  If the Investigator is notified of an inspection 
by a regulatory authority, the Investigator agrees to notify the Sponsor’s medical monitor 
immediately.  By signing this protocol, the Investigator agrees to provide to appropriately 
qualified personnel from such groups, access to records, facilities, and personnel for the effective 
conduct of any inspection or audit. 
10.6. 
Study Oversight Committees 
10.6.1. 
Clinical Adjudication Committee 
As noted in Section 8.6, MACCE event diagnosis will be adjudicated by an independent external 
expert committee. 
10.6.2. 
Steering Committee 
A Steering Committee may be formed, if deemed necessary.  If formed, the committee will be 
comprised of both Sponsor and non-Sponsor scientific experts who will participate in the design, 
conduct, analyses, and publication of the study.  Steering Committee members will remain 
blinded to patients’ treatment assignments and all unblinded data until the database is officially 
locked and unblinded.

10.7. 
Protocol Modifications 
Protocol modifications, except those intended to reduce immediate risk to patients, may be made 
only by the Sponsor.  All protocol modifications must be submitted to the IRB/REB/IEC in 
accordance with local requirements.  Approval must be obtained before changes can be 
implemented.  The Investigator must not deviate from the protocol without first obtaining 
approval from the Sponsor and the IRB/REB/IEC, if required.  In medical emergencies, the 
Investigator will use medical judgment and will remove the patient from immediate hazard, then 
notify the Sponsor (or designee) and the IRB/REB/IEC immediately regarding the type of 
emergency and the course of action taken.  The Investigator must notify the Sponsor (or 
designee) of any inadvertent protocol deviations upon their discovery, and document the 
deviations appropriately in the study files. 
When a protocol amendment substantially alters the study design or the potential risks or burden 
to patients, the informed consent form will be amended and approved by the IRB/REB/IEC, and 
all patients on treatment will again provide informed consent. 
10.8. 
Study Discontinuation 
The Sponsor reserves the right to terminate the study at any time.  Should this be necessary, the 
Sponsor will arrange discontinuation procedures and notify the appropriate regulatory 
authority(ies) and IRB/REB/IEC.  In terminating the study, the Sponsor and the Investigator will 
assure that adequate consideration is given to the protection of the study participants’ interests. 
10.9. 
Publications 
After conclusion of the study and without prior written approval from the Sponsor, Investigators 
in this study may communicate, orally present, or publish in scientific journals or other scholarly 
media only after the following conditions have been met: 
The results of the study in their entirety have been publicly disclosed by or with the consent of 
the Sponsor in an abstract, manuscript, or presentation form; or 
The study has been completed at all study sites for at least 5 years. 
No such communication, presentation, or publication will include Urovant Sciences GmbH 
confidential information (see Section 10.10.5). 
The Investigator will submit to the Sponsor any proposed publication or presentation along with 
the respective target scientific journal or presentation forum at least 30 days before submission of 
the publication or presentation.  The Investigator will comply with Sponsor requests to delete 
references to its confidential information (other than the study results) in any paper or 
presentation and agrees to withhold publication or presentation for an additional 60 days in order 
to obtain patent protection if deemed necessary.

10.10.4. 
Informed Consent 
The Investigator (or designee) is responsible for obtaining written informed consent from each 
study participant prior to any study activities.  To help the individual make an informed decision 
about participating, the Investigator (or designee) shall discuss with the potential participant the 
purpose of the research, procedures, risks, benefits, alternative options to participating, 
confidentiality, how to contact study personnel, and the patient’s rights.  Potential participants 
must be informed that their participation is voluntary and must be given ample time to ask the 
Investigator questions and obtain clarifications regarding the study prior to providing consent. 
The Investigator must utilize an IRB/REB/IEC-approved informed consent form for 
documenting written informed consent that contains all elements required by national, state, 
local, and institutional regulations or requirements.  Each informed consent form will be 
appropriately signed and dated by the patient or the patient’s legally authorized representative 
and the person obtaining consent. 
As described in Section 10.7, patients must be re-consented to participate in the study if a 
protocol amendment is made that substantially alters the study design or the potential risks or 
burden to patients. 
10.10.5. 
Confidentiality 
The Investigator must assure that patients’ anonymity will be strictly maintained and that their 
identities are protected from unauthorized parties.  Only patient number (i.e., not names) and 
date of birth (as allowed) should be recorded on any form or biological sample submitted to the 
Sponsor, IRB/REB/IEC, or laboratory.  The Investigator must keep a Screening log showing 
codes, names, and addresses for all patients screened and for all patients enrolled in the study. 
The Investigator agrees that all information received from the Sponsor, including, but not limited 
to, the IB, protocol, eCRFs and other study forms, the investigational drug, and any other study 
information, remain the sole and exclusive property of the Sponsor during the conduct of the 
study and thereafter.  This information is not to be disclosed to any third party (except employees 
or agents directly involved in the conduct of the study or as required by law) without prior 
written consent from the Sponsor.  The Investigator further agrees to take all reasonable 
precautions to prevent the disclosure by any employee or agent of the study site to any third 
party or otherwise into the public domain. 
10.10.6. 
Study Files and Retention of Records 
The Investigator must maintain adequate and accurate records to enable the conduct of the study 
to be fully documented and the study data to be subsequently verified.  These documents should 
be classified into at least the following two categories: 
Investigator’s study file.  The Investigator’s study file will contain the IB, protocol/amendments, 
IRB/REB/IEC and governmental approval with correspondence, informed consent forms, drug 
records, staff curriculum vitae, authorization and training forms, and other appropriate 
documents and correspondence. 

Clinical Study Protocol 
RVT-901-3003 
Urovant Sciences GmbH

Patient clinical source documents.  The required source data should include the following for 
each patient: 
 Patient identification (name, date of birth, sex); 
 Documentation that the patient meets eligibility criteria, (e.g., history, physical 
examination, and confirmation of diagnosis to support inclusion and exclusion 
criteria); 
 Participation in the study (including study number); 
 Study discussed and date of informed consent; 
 Dates of all visits; 
 Documentation that protocol-specific procedures were performed; 
 Results of efficacy parameters, as required by the protocol; 
 Start and end date (including dose regimen) of Study Treatment (drug dispensing and 
return should be documented as well); 
 Record of all adverse events and other safety parameters (start and end date, and 
causality and intensity as assigned by the Investigator); 
 Concomitant medication (including start and end date); and 
 Date of study completion and reason for early discontinuation, if applicable. 
All clinical study documentation must be retained by the Investigator until at least 2 years after 
the last approval of a marketing application in an ICH region (i.e., United States, Europe, or 
Japan) and until there are no pending or contemplated marketing applications in an ICH region; 
or, if no application is filed or if the application is not approved for such indication, until 2 years 
after the investigation is discontinued and regulatory authorities have been notified.  
Investigators may be required to retain documents longer if required by applicable regulatory 
requirements, by local regulations, or by an agreement with the Sponsor.  The Investigator must 
notify the Sponsor before destroying any clinical study records. 
Clinical study documentation includes the IB, signed protocol and amendments, signed informed 
consents, notification of serious adverse events and related reports, any dispensing and 
accountability logs, shipping records of investigational product and study-related materials, 
documentation of financial aspects of the study, insurance statement, and signed agreement 
between the involved parties, dated and documented IRB/REB/IEC approval, approval of 
regulatory authorities as applicable, decoding procedures for blinded studies, curriculum vitae 
and all training records of study site personnel, and all correspondence pertaining to the conduct 
of the study. 
Should the Investigator wish to assign the study records to another party or move them to another 
location, the Sponsor must be notified in advance. 
If the Investigator cannot guarantee this archiving requirement at the study site for any or all of 
the documents, special arrangements must be made between the Investigator and the Sponsor to 
store these in sealed containers outside of the site so that they can be returned sealed to the 
Investigator in case of a regulatory audit.  When source documents are required for the continued 
care of the patient, appropriate copies should be made for storage outside of the site.

10.10.7. 
Electronic Case Report Forms 
For each patient enrolled, an eCRF must be completed and signed by the Investigator or 
Sub-Investigator (as appropriate) listed on Food and Drug Administration Form 1572 and/or 
other appropriate local health authority documents within a reasonable time period after data 
collection.  This also applies to records for those patients who fail to complete the study (even 
during a pre-randomization Screening Period if an eCRF was initiated).  If a patient withdraws 
from the study, the reason must be noted on the eCRF.  If a patient is withdrawn from the study 
because of a treatment-limiting adverse event, thorough efforts should be made to clearly 
document the outcome. 
10.10.8. 
Investigational Product Accountability 
The Investigator or Investigator’s designee (e.g., pharmacist) is responsible for ensuring 
adequate accountability (including dates and lot numbers) of all used and unused Study 
Treatment (active and placebos).  This includes acknowledgment of receipt of each shipment of 
study product (quantity and condition), patient dispensing records, and returned or destroyed 
study product.  Dispensing records will document quantities received from the Sponsor and 
quantities dispensed to patients, including lot number, date dispensed, Patient Number, and the 
initials of the person dispensing the Study Treatment. 
At study initiation, the study monitor will evaluate the site’s standard operating procedure for 
investigational medicinal product disposal/destruction in order to ensure that it complies with the 
Sponsor requirements.  Drug may be returned (by the monitor) or destroyed on-site, if 
appropriate per site standard operating procedures (SOPs).  At the end of the study, following 
final drug inventory reconciliation by the monitor, the study site will dispose of and/or destroy 
all unused Study Treatment supplies, including empty containers, according to these procedures.  
If the site cannot meet the Sponsor’s requirements for disposal, arrangements will be made 
between the site and the Sponsor (or designee) for destruction or return of unused investigational 
medicinal product supplies. 
All drug supplies and associated documentation will be periodically reviewed and verified by the 
study monitor over the course of the study. 
10.11. 
Sponsor-Specific Responsibilities 
10.11.1. 
Study Report 
A clinical study report will be prepared and provided to the regulatory authority(ies).  The 
Sponsor will ensure that the report meets the standards set out in the ICH Guideline for Structure 
and Content of Clinical Study Reports (ICH E3).  Note that an abbreviated report may be 
prepared in certain cases. 
10.11.2. 
Posting of Information on Publicly Available Clinical Trial Registers 
Study information from this protocol will be posted on publicly available clinical trial registers 
before enrollment of patients begins.  Results will be posted as required.

APPENDIX B. ALGORITHM FOR ASSESSING LABORATORY VALUES 
For all laboratory values obtained at pre-study evaluation: 
1. If all values are normal, the patient may enter the study. 
2. If a value is outside the normal range, the following choices are available: 
 The patient may be excluded from the study; 
 The abnormal test may be repeated. 
 The result may be deemed “Not Clinically Significant” and the patient may be 
enrolled in the study. 
3. If the Investigator decides to repeat an abnormal test and if it is within the normal range, 
the patient may enter the study. 
4. If the Investigator decides to repeat an abnormal test and if the repeat test is still 
abnormal, the Investigator will evaluate the potential patient with a complete history and 
physical examination, looking especially for diseases that could result in an abnormality 
in the laboratory value in question.  If such diseases can be excluded, and if the 
Investigator feels that the abnormal laboratory value is not clinically relevant, then the 
patient may enter the study.  The Urovant clinical monitor will be included in the 
decision of whether or not to enroll the patient in the study. 
5. If there is any clinical uncertainty regarding the significance of an abnormal value, the 
patient will be excluded from the study.

APPENDIX D. GUIDELINES FOR ELEVATIONS IN HEPATIC 
ENZYMES 
Study treatment should be withheld for any liver test abnormality listed in Section 8.6.1, pending 
investigation of alternative causes of liver injury.  Follow-up should continue until the liver test 
abnormalities resolve to baseline. 
Monitor liver tests per the applicable schedule in Table D-1, and per the investigations in 
Table D-2.  If close monitoring is not possible, Study Treatment should be withheld, even if the 
results do not meet the criteria for withholding in Section 8.6.1. 
The medical monitor should be contacted for questions regarding adequate follow-up tests and 
frequency of follow-up tests for a patient.

Table D-2 
Investigations of Alternative Causes for Abnormal Liver Tests 
Obtain a detailed history and perform a physical examination: 
 Detailed history of symptoms (e.g., right upper quadrant pain, fatigue, nausea, vomiting, 
and fever); 
 Prior and concurrent disease or illnesses; 
 Exposure to environmental (e.g., travel, new sexual exposure, exposure to ill family 
members or coworkers, etc.) and/or industrial chemical agents; 
 Prior and concurrent use of alcohol, recreational drugs, and special diets; 
 Concomitant use of medications (including nonprescription medicines and herbal and 
dietary supplements), plants and mushrooms; 
 Physical examination. 
Recommended tests: 
 Also perform additional tests as clinically indicated or in consultation with a 
gastroenterologist or hepatologist. 
 Repeat liver tests as per Table D-1a; 
 Obtain gamma-glutamyl transferase, albumin, INR, and glucose in conjunction with 
repeat liver tests; 
 Complete blood count with differential to assess for eosinophilia; 
 Serum acetaminophen (paracetamol) concentration; 
 Obtain viral serologies for hepatitis A, B, C, D, and E; consider testing for Epstein Barr 
virus; 
 Evaluate for alcoholic hepatitis, nonalcoholic steatohepatitis, biliary tract disease, 
autoimmune hepatitis, etc.; 
 Serology for celiac disease; 
 Appropriate liver imaging; and 
 Hepatology consult (liver biopsy may be considered in consultation with a hepatologist 
or gastroenterologist). 
Abbreviations:  INR, international normalized ratio 
a. If the first follow-up testing does not confirm the initial abnormal liver test results, review any additional follow-
up monitoring with the medical monitor.
