Protocol Summary 
1.1. 
Synopsis 
Protocol Title: A Phase 3b, Open-Label, Single-Arm, Multicenter Study to Assess the 
Feasibility of Home Instillation of UGN-102 for Treatment of Patients with 
Low-Grade (LG) Non-Muscle-Invasive Bladder Cancer (NMIBC) at 
Intermediate Risk (IR) of Recurrence 
Overall Design: This Phase 3b, open-label, single-arm, multicenter study is designed to assess 
the feasibility of home instillation of UGN-102 (mitomycin) for intravesical solution in 
approximately 10 patients with low-grade (LG) intermediate risk (IR) non-muscle-invasive 
bladder cancer (NMIBC). 
The primary objective of this study is to evaluate the feasibility of home instillation of UGN-102 
as an alternative to instillation in a clinical setting. Feasibility will be assessed by evaluation of 
safety and tolerability, rate of discontinuation from at home study treatment, and feedback from 
patients, home health professionals, and investigators via standardized questionnaires. The 
secondary objective of this study is to evaluate the efficacy of UGN-102 for the treatment of 
LG IR NMIBC following home instillation. Efficacy will be assessed at the 3-month Visit 
(3 months after the first instillation of UGN-102) by complete response rate (CRR), defined as 
the proportion of patients who achieved complete response (CR) as determined by cystoscopy, 
for cause biopsy, and urine cytology. 
Patients who provide informed consent will undergo a Screening Visit to determine eligibility. 
Approximately 10 patients ≥ 18 years of age with LG IR NMIBC who meet the eligibility 
criteria will receive 6 once weekly intravesical instillations of UGN-102. The first instillation 
will be performed at the investigative site and subsequent instillations will be performed at the 
patient’s home by a properly trained and qualified home health professional. 
End-of-study (EOS) is defined as the last patient last visit (LPLV). The EOS will be declared 
after all patients have completed the 3-month Visit (7 weeks ± 1 week after the final instillation 
of UGN-102).  
Following the 3-month Visit, all patients will exit the study and continue with standard of care 
according to their treating physician.

a. 
The Screening Period is up to 14 days for patients who do not need a Screening biopsy and up to 28 days for patients who need a Screening biopsy. Screening procedures are required to 
provide evidence of LG NMIBC and no evidence of HG disease. 
b. 
Windows are provided to accommodate patient logistics in scheduling. Treatment instillations should occur 6 to10 days apart. Every effort should be made to minimize the time interval 
between diagnosis and Treatment Visit 1 (the maximum interval from end of Screening to first instillation should be ≤ 7 days). 
c. 
Obtain written informed consent before any study-related procedures are performed.  
d. 
Any past therapy (eg, pharmacological or surgical interventions) related to UC will be recorded during Screening. 
e. 
A full physical examination will be performed at the Screening Visit by a physician at the investigative site (Section 9.3.1). Additional full physical examinations may be performed 
during the study if clinically indicated. 
f. 
A urological examination will be performed at the Screening Visit, Treatment Visit 1, and at the 3-month Visit (or ET) by a physician at the investigative site (Section 9.3.1). The 
urological examination should be performed before cystoscopy at relevant visits. Additional urological examinations may be performed during the study if clinically indicated. Any 
clinically relevant changes in urological examinations will be recorded on the AE sections of the eCRF. 
g. 
Clinical assessment will be performed before study drug instillation. Body systems to be reviewed include general appearance and urethral meatus (Section 9.3.1). Abnormal findings 
observed at home instillation visits will be documented and reported by the home health professional to the investigative site during the visit. 
h.

Introduction 
Non-Muscle-Invasive Bladder Cancer 
Bladder cancer is the sixth most common cancer in the US, with an expected 81,000 new cases 
diagnosed in 2020 (ACS, 2020). At the time of diagnosis, 75% of patients present with NMIBC 
(Babjuk et al, 2019; Monteiro et al, 2019). NMIBC includes a clinically heterogeneous group of 
cancers with a wide range of recurrence and progression probabilities (Chang et al, 2016). 
Therefore, treatment guidelines recommend classifying patients with NMIBC as being at low, 
intermediate, or high risk of disease recurrence and/or progression (Babjuk et al, 2019; Chang 
et al, 2016; Kamat et al, 2014). While the management of low risk and high-risk patients appears 
clear, the best treatment option for intermediate risk patients remains undefined (Monteiro et al, 
2019). Based on analysis of the Surveillance, Epidemiology, and End Results (SEER) Program 
SEER*Stat Database, UroGen estimates that LG IR NMIBC represents approximately 25% of 
newly diagnosed bladder cancer cases in the US (SEER Program, 2019). 
The current standard of care for treatment of LG IR NMIBC is TURBT under general anesthesia 
(NCCN, 2020; Chang et al, 2016). Due to the persistent and recurrent nature of the disease (30% 
to 50% recur at 1 year; Babjuk et al, 2019), patients with LG IR NMIBC often endure repeated 
TURBTs under general anesthesia, which research has shown to be associated with significant 
postoperative and long-term morbidity and an increased risk of overall death (Erikson et al, 2020; 
Pereira et al, 2019; Avallone et al, 2017; Ghali et al, 2016; Matulewicz et al, 2015; Patel et al, 
2015; De Nunzio et al, 2014; Hollenbeck et al, 2006; Balbay et al, 2005). Rates of 30-day 
complications (11%), unplanned hospital readmissions (5%), and mortality (1%) following 
TURBT yield a significant number of patients at risk given the high volume of this procedure 
(Erikson et al, 2020; Patel et al, 2015; Rambachan et al, 2014). The totality of evidence, 
including procedural limitations (eg, incomplete resection of tumors; Daneshmand et al, 2018; 
Miyake et al, 2016), postoperative complications, and the high recurrence rate of NMIBC, 
suggests that the current, primarily surgical approach to treatment is suboptimal. 
Short-term, chemoablative therapy with UGN-102 has the potential to serve as a primary 
nonsurgical treatment option for LG IR NMIBC, especially among this population of 
predominantly elderly and multimorbid patients, by whom surgery and anesthesia are poorly 
tolerated. Studies in the peer-reviewed literature (Lindgren et al, 2020; Mostafid et al, 2020; 
Colombo et al, 2012) and data from the UGN-102 clinical development program suggest that 
chemoablation with mitomycin may obviate the need for surgery in some patients or reduce the 
perioperative morbidity associated with surgery secondary to lower volume disease, and may be 
associated with fewer clinically significant adverse effects. 
UGN-102 
UGN-102 (mitomycin) for intravesical solution is a reverse thermal gel formulation of 
mitomycin designed for initial nonsurgical treatment of LG IR NMIBC, and to potentially 
obviate the need for repetitive TURBT. The reverse thermal properties of UGN-102 allow for the 
local administration of mitomycin as a liquid in a cooled state, with subsequent conversion to a 
semi-solid gel depot at body temperature following instillation into the bladder cavity. The gel 
slowly disintegrates and is excreted by normal urine flow, allowing for the sustained release of 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
17 
mitomycin over a period of 4 to 6 hours. The prolonged exposure of tumor cells to mitomycin 
leads to improved chemoablation compared with aqueous preparations of mitomycin. 
The efficacy and safety of UGN-102 for the treatment of patients with LG IR NMIBC was 
evaluated in a Phase 2b, single-arm, multicenter study (BL005). Intravesical instillation of 
UGN-102 once weekly for 6 weeks resulted in high rates of CR at 3 months and durable 
complete response (DCR) at 12 months after the start of study treatment. A total of 63 patients 
were enrolled and treated with UGN-102. Forty-one (65.1%) patients achieved the primary 
endpoint of CR at 3 months after the first instillation of UGN-102 (95% CI of CR rate: 52.0, 
76.7), and 25/41 (61.0%) patients had a DCR at 12 months after the first instillation (95% CI of 
DCR rate: 44.5, 75.8). The 9-month duration of response rate as estimated by the Kaplan-Meier 
method was 72.5% (95% CI: 54.4, 84.3), ie, the probability that a patient will maintain CR for at 
least 9 months is 72.5%. The overall safety profile of UGN-102 was favorable, with primarily 
mild to moderate adverse events (AEs), no treatment-related serious adverse events (SAEs) or 
hospitalizations, low number of treatment discontinuations, and no clinically meaningful trends 
or pattern of changes identified in laboratory parameters, vital signs, or physical examinations.  
Based on the favorable tolerability profile and the vulnerability of this patient population, the 
intent of this study is to demonstrate that UGN-102 may be safely and feasibly administered in the 
home setting.  
Further details regarding the development of UGN-102 can be found in the UGN-102 
Investigator’s Brochure (IB). 
2.1. 
Study Rationale 
This study aims to demonstrate that home instillation of UGN-102 is a feasible alternative to 
instillation in a clinical setting. Potential advantages of home instillation include but are not 
limited to: 
• moving healthcare out of the clinical setting and into a patient’s home, potentially 
reducing hospital resource utilization. 
• decreased risk of exposure to infections observed in the healthcare setting. 
• simplifying travel logistics, decrease travel expenditures, decrease clinic waiting periods 
for the patient.  
• decreased burden to family members who might otherwise need to transport patient to 
and from clinical setting. 
• receiving cancer treatment in a familiar environment.

2.2. 
Benefit-Risk Assessment 
Further details regarding the benefit-risk profile of UGN-102 for treatment of LG IR NMIBC can 
be found in the UGN-102 IB. 
2.2.1. 
Risk Assessment 
Cystitis and Lower Urinary Tract Symptoms  
Cystitis and other lower urinary tract symptoms (LUTS) may develop. These symptoms are well 
known in relation to standard mitomycin instillations and are not specific to UGN-102. Urine 
tests, including urinalysis and urine culture as indicated, will be checked regularly during the 
study to monitor for potential UTI. Any signs and/or symptoms of UTI will be treated by the 
Investigator according to local practice. 
Toxicity Associated with Systemic Absorption/Local Irritation 
Bladder toxicity and rarely bone marrow toxicity (thrombocytopenia and leukopenia) are 
considered possible risks for patients when mitomycin is administered topically. Complete blood 
count and renal and liver function tests will be checked during the study (Table 4), and the 
Investigator will follow any clinically significant abnormality until it is resolved, stabilized, or 
otherwise managed (Section 9.3.3). 
Allergic Response to Mitomycin 
Allergic reactions during mitomycin bladder instillations are well described and have been 
observed during previous studies with UGN-102. Toxicities were generally manageable by 
treating patients with antihistamine drugs before and after treatment, and with systemic steroids 
as needed. Signs of an allergic response will be closely monitored during the study and managed 
by the Investigator according to local practice. 
Instillation Procedure  
The insertion of a urethral catheter requires manipulation of the urethra and bladder. Some pain 
and discomfort are expected given the intravesical route of administration.  
Potential risks of urethral catheterization include catheter associated UTIs, soreness, bleeding, 
bruising, and kidney infections. 
The first study treatment instillation will be performed at the investigative site by a qualified 
physician. Treatment Visits 2 to 6 will occur at the patient’s home and study treatment 
instillation will be performed by a properly trained and qualified home health professional. To 
the extent possible, the same home health professional will perform home instillation of study 
treatments for a given patient.  
If the assigned home health professional is unable to perform the study treatment instillation on a 
scheduled dose day, another trained and qualified home health professional will perform the 
required study treatment instillation (Section 7.1.3.1). 
The patient will be monitored for AEs during and for at least 60 minutes after each study 
treatment instillation.  

CONFIDENTIAL 
Protocol BL010 version 1.0

2.2.2. 
Benefit Assessment 
The potential advantages of instillation of mitomycin in hydrogel include: 
• Extended exposure of drug for up to 6 hours (compared with 1.5 to 2 hours in standard 
instillation). Published literature indicates that duration of tumor exposure to 
chemotherapy is critical to its ablative response. Thus, the effectiveness of tumor ablation 
is increased by longer dwell times. 
• The hydrogel protects mitomycin from being diluted by urine, which leads to longer 
stable chemotherapy concentration levels. 
These characteristics of UGN-102 (mitomycin + sterile hydrogel) are expected to improve 
mitomycin treatment efficacy and provide an alternative mode of ablation for NMIBC, which 
may be simpler and potentially better tolerated than current treatment modalities. 
Instillation Procedure 
Potential benefits of providing medical care at home include patient convenience, comfort and 
logistical ease, decreased risk of nosocomial infections, decreased exposure to others who may 
transmit infections such as the COVID-19 virus, influenza, or common “cold” virus 
(eg, rhinoviruses and adenoviruses), and decreased burden on family members who might 
otherwise be responsible for transporting patients to and from procedures. Other potential 
benefits include increased patient engagement and compliance in study procedures.  
2.2.3. 
Overall Benefit-Risk Conclusion 
Overall, based on the efficacy and safety results observed to date, UGN-102 has a favorable 
benefit-risk profile for the treatment of LG IR NMIBC. Additionally, based on the favorable 
tolerability profile and the vulnerability of this patient population, home instillation of UGN-102 
may be a feasible treatment paradigm and offer potential advantages compared with instillation 
in a clinical setting.

Study Design 
4.1. 
Overall Design 
This Phase 3b, open-label, single-arm, multicenter study is designed to assess the feasibility of 
home instillation of UGN-102 (mitomycin) for intravesical solution in approximately 10 patients 
with LG IR NMIBC. 
The primary objective of this study is to evaluate the feasibility of home instillation of UGN-102 as 
an alternative to instillation in a clinical setting. Feasibility will be assessed by evaluation of safety 
and tolerability, rate of discontinuation from at home study treatment, and feedback from patients, 
home health professionals, and investigators via standardized questionnaires. The secondary 
objective of this study is to evaluate the efficacy of UGN-102 for the treatment of LG IR NMIBC 
following home instillation. Efficacy will be assessed at the 3-month Visit (3 months after the first 
instillation of UGN-102) by CRR, defined as the proportion of patients who achieved CR as 
determined by cystoscopy, for cause biopsy, and urine cytology. 
Patients who provide informed consent will undergo a Screening Visit to determine eligibility. 
The Screening Period is up to 14 days for patients who do not need a Screening biopsy and up to 
28 days for patients who need a Screening biopsy. Screening procedures are required to provide 
evidence of LG NMIBC and to rule out evidence of HG disease (Section 1.3).  
A single representative cold cup biopsy to confirm LG tumor will be performed only if not 
already performed within 8 weeks before Screening. This is a diagnostic biopsy to demonstrate 
the histopathology of the tumor, and resection of tumor is not to be performed (Section 1.3). 
Patients will receive 6 once weekly intravesical instillations of study treatment. The first 
instillation will be performed at the investigative site and subsequent instillations will be 
performed at the patient’s home by a properly trained and qualified home health professional. 
The home health professional will call the patient 1 day (+1 day) after each home instillation of 
study treatment to monitor for safety (Section 1.3).  
The UGN-102 concentration to be used in this study will be 1.33 mg mitomycin per 1 mL 
admixture. The volume of UGN-102 admixture to be instilled will be 56 mL (75 mg of 
mitomycin) (Section 7.1.3). 
At each home instillation visit, the patient and home health professional will complete a 
feasibility questionnaire. In addition, the patient and investigator will complete a feasibility 
questionnaire at the 3-month Visit (EOS) or ET Visit (Section 1.3 and Section 9.9). 
Patients will return to the clinic for the 3-monthVisit (7 weeks ± 1 week after the final instillation 
of UGN-102) for determination of response to treatment.  
Response to study treatment will be determined based on visual evaluation by cystoscopy (white 
light) (appearance, number, and size of any remaining lesions), interpretation of urine cytology, 
and for cause biopsy and histopathology of any remaining lesions (Section 9.2.2). Any lesions or 
suspect tissue must be biopsied to evaluate for persistence of disease. 
If an unscheduled visit is required during the study, assessments should be performed as 
appropriate to the needs of the visit. 

CONFIDENTIAL 
Protocol BL010 version 1.0

Safety will be evaluated based on vital signs, physical examination, laboratory assessments, and a 
review of AEs. All safety data will be reviewed on an ongoing basis by the Sponsor, including close 
review and follow up of any unexpected AE assessed as related to UGN-102 (Section 9.4.1.3.3), 
and qualified per National Cancer Institute Common Terminology Criteria for Adverse 
Events (CTCAE) as Grade 3 or 4 (Section 9.4.1.3.1). 
A patient will be considered to have completed the study if the patient completes the 3-month 
Visit in accordance with the Schedule of Activities (SoA) (Section 1.3). 
Following the 3-month Visit, all patients will exit the study and continue with standard of care 
according to their treating physician. 
End-of-study is defined as the LPLV. The EOS will be declared after all patients have completed 
the 3-month Visit.  
4.2. 
Scientific Rationale for Study Design 
UroGen estimates that LG IR NMIBC represents approximately 25% of newly diagnosed 
bladder cancer cases in the United States (SEER Program, 2019). While TURBT remains the 
current surgical standard of care for treatment of LG IR NMIBC (NCCN, 2020, Chang et al, 
2016), Study BL005 (OPTIMA II) showed a favorable efficacy and safety profile with 6 once 
weekly intravesical instillations of UGN-102 (75 mg mitomycin) as an alternative to surgery, and 
demonstrated durable clinical response in patients with LG IR NMIBC (Huang et al, 2020).  
Intravesical instillation of UGN-102 may become a viable alternative to TURBT for these 
patients and is under evaluation in a Phase 3 study (BL006). One of the benefits of UGN-102 is 
the ability to safely administer in the outpatient setting by personnel trained in bladder 
catheterization with appropriate physician oversight. This study aims to demonstrate that home 
instillation of UGN-102 is a feasible alternative to instillation in a clinical setting, which might 
mitigate some of the challenges in the patient experience (logistical, expense, and comfort) when 
receiving treatment for LG IR NMIBC. 
The COVID-19 pandemic has created an unprecedented need to re-evaluate the entirety of global 
healthcare and specifically the cancer care delivery system. Home instillation of antitumor therapy 
is not new outside the US, and internationally approximately 5%-10% of patients diagnosed with a 
range of cancers receive antitumor therapy at home (Lal et al, 2013; Luthi et al, 2012; Innominato 
et al, 2016). This global practice could be considered a model for feasibility in the US for in-home 
antitumor therapy delivery. Pointedly so during an unprecedented time when in-home consultation 
and care are increasingly sought, becoming familiar to patients, and recognizably viable by both 
the patient and the healthcare provider; all thereby, mitigating increased risk of morbidity and 
mortality from COVID-19 and other readily transmissible infectious diseases (Handley and 
Bekelman, 2019; Handley et al, 2020; Laughlin et al, 2020; Dai et al, 2020).  
A re-evaluation of in-home delivery of cancer treatments in the US is not only a reasonable task 
during the current pandemic, but a potential viable option for post-pandemic practice leading to 
care that benefits the overall health, well-being and safety of patients diagnosed with certain 
cancers. Intravesical catheterization delivery of immunotherapy has been performed by trained 
medical professionals for superficial bladder cancer for over 45 years (Fuge et al, 2015). Thus, 
the procedure is foundational and having the flexibility to receive treatment by a trained and 
qualified home health professional at home may change the landscape of LG NMIBC treatment. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
23 
Further, feasibility for in-home treatment instillation of UGN-102 may be tested in this 
subpopulation of cancer patients given that LG IR NMIBC has a well-understood clinical 
behavior over time (Marcq et al, 2019; Hurle et al, 2018; Tiu et al, 2014) and the recent 
promising results of the OPTIMA II trial (Huang et al, 2020).  
4.3. 
Justification for Dose  
The UGN-102 dose of 75 mg was chosen based on both efficacy and tolerability. Study BL003 
demonstrated a numerically higher CRR for the 75 mg dose than for the 37.5 mg dose. In Study 
BL004, 120 mg of UGN-102 had a similar response rate and a higher rate of AEs than the 75 mg 
dose in Study BL003. Study BL005 showed a favorable efficacy and safety profile with 6 once 
weekly instillations of 75 mg UGN-102. Results showed a considerable treatment response with 
encouraging durability. The overall safety profile of UGN-102 was favorable, with primarily 
mild to moderate AEs, no treatment-related SAEs or hospitalizations, low number of treatment 
discontinuations, and no clinically meaningful trends or pattern of changes identified in 
laboratory parameters, vital signs, or physical examinations. 
4.4. 
End-of-Study Definition 
EOS will be declared after all patients have completed the 3-month Visit (7 weeks ± 1 week after 
the final instillation of UGN-102). 
The EOS is defined as LPLV.

Product Quality Complaint Handling 
A PQC is defined as any suspicion of a product defect related to manufacturing, labeling, or 
packaging; ie, any dissatisfaction relative to the identity, quality, durability, or reliability of a 
product, including its labeling or packaging integrity. In such cases, and also in cases of 
temperature deviation, either during transport, storage, or preparation at the pharmacy, or during 
transport to patient’s home, the Investigator is responsible for notifying the Sponsor about the 
defect/temperature deviation. Any PQCs must be reported to the Sponsor/Sponsor Designee 
using: 
 or 
. 
Reporting must be done upon first awareness, and the site should await the Sponsor’s decision 
regarding the drug’s validity before drug dispensing. 
If the PQC is associated with an SAE, the investigational staff must report the PQC to the 
Sponsor/Sponsor Designee as described above and the SAE(s) must be reported according to 
Section 9.4.6 (Serious Adverse Event Reporting). The affected study products must be 
quarantined and marked “not for use” during investigation until a decision has been made 
regarding the drug’s usability. 
Product quality complaints may have an impact on the safety and efficacy of the product. Timely, 
accurate, and complete reporting and analysis of PQC information from clinical studies are 
crucial for the protection of patients, Investigators, and the Sponsor, and are mandated by 
regulatory agencies worldwide. The Sponsor has established procedures in conformity with 
regulatory requirements worldwide to ensure appropriate reporting of PQC information; all 
clinical studies conducted by the Sponsor or its affiliates will be conducted in accordance with 
those procedures.

Discontinuation of Study Treatment and Patient 
Discontinuation/Withdrawal 
8.1. 
Discontinuation of Study Treatment 
Discontinuation from study treatment does not mean discontinuation from the study, and 
remaining study procedures should be completed as indicated by the study protocol (ie, 3-month 
Visit). If a clinically significant finding is identified (including, but not limited to, changes from 
baseline) after enrollment, the Investigator or qualified designee will determine if any change in 
patient management is needed. Any new clinically relevant finding will be reported as an AE. 
8.1.1. 
Temporary Withholding of Study Treatment  
If at any time during the study the Investigator identifies clinically significant myelosuppression, 
evidence of an active UTI, or any other significant clinical event or laboratory derangements 
defined by the parameters below, treatment may be postponed for up to 4 weeks until the clinical 
event resolves and/or laboratory values improve (Section 9.3.3.1): 
• Absolute neutrophil count ≤ 1,000/μL (≥ 1.0×109/L). 
• Platelets ≤ 80,000/μL (≤ 80×109/L). 
• AST/ALT ≥ 5 × ULN. 
• Laboratory evidence of active UTI.

If the patient withdraws consent for in-home instillation of study treatment, the patient may 
continue treatment and all scheduled assessments at the investigative site.  
8.2. 
Patient Discontinuation/Withdrawal from the Study  
A patient in this study may withdraw from the study at any time at his/her own request or may be 
withdrawn at any time at the discretion of the Investigator for safety, behavioral, or compliance 
reasons. 
A patient will be considered to have withdrawn from the study for any of the following: 
• Withdrawal of consent 
• Lost to follow-up 
• No longer being followed at the Investigator’s discretion 
• Protocol non-compliance 
• Pregnancy  

CONFIDENTIAL 
Protocol BL010 version 1.0

• Patient experienced an AE that led to study discontinuation 
• Death 
• Study is closed or terminated by the sponsor 
The reason for patient discontinuation or withdrawal from the study will be recorded on the eCRF. 
At the time of early discontinuation from the study, if possible, an ET Visit should be conducted 
as shown in the SoA. See Section 1.3 for data to be collected at the time of early discontinuation 
and for any further evaluations that need to be completed. The patient will be permanently 
discontinued both from the study treatment and from the study at that time. 
8.3. 
Lost to Follow-up 
A patient will be considered lost to follow-up if he or she fails to be available for 2 sequential 
scheduled home instillation visits and is unable to be contacted by the investigative site staff.  
The following actions must be taken if a patient fails to return to the clinic for a required 
study visit: 
• The site will attempt to contact the patient and reschedule the missed visit as soon as 
possible and counsel the patient on the importance of maintaining the assigned visit 
schedule and ascertain if the patient wishes to and/or should continue in the study. 
• Before a patient is deemed lost to follow-up, the Investigator or designee will make every 
effort to regain contact with the patient (where possible, 3 telephone calls and, if 
necessary, a certified letter to the patient’s last known mailing address or local equivalent 
methods). These contact attempts should be documented in the patient’s study file.  
Should the patient continue to be unreachable, he or she will be considered to have withdrawn 
from the study with a primary reason of lost to follow-up.

Study Assessments and Procedures 
Adherence to the study design requirements, including those specified in the SoA (Section 1.3), 
is essential and required for study conduct. 
All Screening evaluations must be completed and reviewed to confirm that potential patients 
meet all eligibility criteria. The Investigator will maintain a Screening log to record details of all 
patients screened and to confirm eligibility or record reasons for Screening failure, as applicable. 
Procedures conducted as part of the patient’s routine clinical management (eg, blood count) and 
obtained before signing of the ICF may be utilized for Screening or baseline purposes provided 
the procedures met the protocol-specified criteria and were performed within the time frame 
defined in the SoA (Section 1.3). 
9.1. 
Study Assessments and Procedures by Visit 
See the SoA in Section 1.3 for the timing and schedule of all study procedures and assessments.  
If an unscheduled visit is required during the study, assessments should be performed as 
appropriate to the needs of the visit. 
9.2. 
Efficacy Assessments 
Efficacy will be assessed at the 3-month Visit.  
9.2.1. 
Measurements for Evaluation of Response at 3-month Visit 
Assessment of response will be based on the following: 
• Visual observation (white light cystoscopy) 
• Biopsy of remaining lesions, if applicable (non-complete response [NCR] or 
suspected tissue) 
• Voiding urine cytology 
9.2.2. 
Evaluation of Treatment Response at 3-month Visit (Disease Assessment) 
Patient response will be evaluated according to the following criteria: 
• CR: A patient will be considered to have had CR if there is no detectable disease (NDD) 
at bladder. To determine NDD, the following conditions should be fulfilled: 
1. If visual assessment indicates no remaining tumors and urine cytology is not 
consistent with the presence of UC, the patient has NDD and CR.  
2. If any remaining lesions appear, even if they appear necrotic, the physician should 
biopsy the lesion(s). If histopathology is negative, the patient should be classified as 
having CR; if positive for cancer, the patient should be classified as NCR. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
36 
• NCR: A patient will be considered to have had NCR if there is evidence of disease 
under study: 
1. If tumors are still visible, all remaining lesions should be biopsied for histopathology 
and viability assessment. If histopathology still indicates cancer, then the patient is 
considered NCR. Note that biopsy results showing papillary urothelial neoplasm of 
low malignant potential are not considered cancer and in such cases the patient would 
be considered CR. 
• If evidence of disease is identified, patients will be staged according to the 
Tumor-Node-Metastases classification and graded according to the 2004 World Health 
Organization classification of tumors. Any noted progression of tumor in terms of 
transition to high grade, muscle invasion, distant disease (local assessment) will be 
documented by the site in the eCRF. 
• In the rare event that the bladder is free of tumor endoscopically, but the cytology is 
consistent with UC, the urine cytology should be repeated. Note that atypical cells 
identified on urine cytology are not consistent with LG NMIBC, and that abnormal urine 
cytology findings require clinical context to support interpretation, particularly in the 
presence of a normal cystoscopy.  
1. If the repeat urine cytology is consistent with UC, the Investigator is required to 
exclude UC of the upper tract and occult carcinoma of the bladder or urethra.  
2. If UTUC is confirmed, the patient will be considered as CR for LG NMIBC. If 
UTUC is not confirmed, the Investigator must perform random bladder biopsies to 
examine the following 6 bladder mucosal sites: bladder floor, right wall, left wall, 
dome, posterior wall, and prostatic urethra (in males) or bladder neck (in females). 
3. If histopathology is negative, the patient should be classified as having CR; if positive 
for cancer, the patient should be classified as NCR. 
9.2.3. 
Pathological Evaluation 
Biopsies and urine cytology specimens obtained at Screening or any other visit should be 
evaluated by the local laboratory (pathologist) facility. Pathology reports from local laboratory 
facilities will be provided to Investigators. 
9.3. 
Safety Assessments 
The safety of study treatment will be assessed by the following: 
• Evaluation (frequency, seriousness, severity, and type) of AEs including adverse events 
of special interest (AESIs) 
• Changes from baseline in laboratory values and incidence of measurements defined as 
potentially clinically significant  
• Clinically meaningful changes in physical examination findings including vital signs. 
Planned time points for all safety assessments are provided in the SoA (Section 1.3).

The Investigator must review the laboratory report, document this review, and record any 
laboratory abnormalities as clinically significant or not clinically significant. Any clinically 
significant changes should have a corresponding AE reported. The laboratory reports must be 
filed with the source documents. 
Abnormal laboratory findings associated with the underlying disease are not considered 
clinically significant unless judged by the Investigator to be more severe than expected for the 
patient’s condition. 
All laboratory tests with values considered clinically significantly abnormal during participation 
in the study (eg, in case of either temporary discontinuation) or within 4 weeks after the last 
administered dose of study treatment (ie, in case of permanent discontinuation) should be 
repeated until the values return to normal or baseline or are no longer considered clinically 
significant by the Investigator or medical monitor. 
If any clinically significant or other values do not return to normal/baseline within a period of 
time judged reasonable by the Investigator, the etiology should be identified, and the Sponsor 
notified. 
All protocol-required laboratory tests, as defined in Table 4, must be conducted in accordance 
with the laboratory manual and the SoA (Section 1.3). 
A local laboratory will be used in this study. If laboratory values from non-protocol specified 
laboratory tests performed at the institution’s local laboratory require a change in patient 
management or are considered clinically significant by the Investigator (eg, AE), then the results 
must be recorded.

9.4.1. 
AEs and SAEs 
9.4.1.1. 
Definition of AE 
An AE means any untoward medical occurrence associated with the use of an intervention in 
humans, whether or not considered intervention-related (21 CFR 312.32 [a]; European Directive 
2001/20/EC). An AE can therefore be any unfavorable and unintended sign, symptom, or disease 
temporally associated with the use of a medicinal (investigational) product, whether or not 
related to the medicinal (investigational) product (“Note for Guidance on Good Clinical 
Practice” CPMP/ICH/135/95).  
Events Meeting the AE Definition 
• Any abnormal laboratory test results (hematology, serum chemistry, or urinalysis) or 
other safety assessments (eg, electrocardiogram, radiological scans, vital signs 
measurements), including those that worsen from baseline, considered clinically 
significant in the medical and scientific judgment of the Investigator (ie, not related to 
progression of underlying disease). 
• Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition. 
• New conditions detected or diagnosed after study treatment administration even though it 
may have been present before the start of the study. 
• Signs, symptoms, or the clinical sequelae of a suspected intervention-intervention 
interaction. 
• Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication. Overdose per se will not be reported as an 
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-harming 
intent. Such overdoses should be reported regardless of sequelae. 
• “Lack of efficacy” or “failure of expected pharmacological action” per se will not be 
reported as an AE or SAE. Such instances will be captured in the efficacy assessments. 
However, the signs, symptoms, and/or clinical sequelae resulting from lack of efficacy 
will be reported as AE or SAE if they fulfil the definition of an AE or SAE. 
Events NOT Meeting the AE Definition 
• Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments, which are associated with the underlying disease, unless judged by the 
Investigator to be more severe than expected for the patient’s condition. 
• 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 (eg, endoscopy, appendectomy): the condition that leads to 
the procedure is the AE. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
41 
• Situations in which an untoward medical occurrence did not occur (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. 
Any patient who reports an AE shall be examined by a doctor as soon as possible, making 
whatever intervention is necessary for the safety and well-being of the patient. All anomalies 
shall be monitored through to the patient’s recovery or clinical stabilization. Collected reportable 
AEs must be recorded in the eCRF using CTCAE version 5.0 (CTCAE, 2017) to avoid the use of 
vague, ambiguous, or colloquial expressions. The Investigator shall evaluate all collected 
reportable AEs in terms of severity and their relationship with the product being tested, 
indicating the test results and the measures to be taken. 
9.4.1.2. 
Definition of SAE  
An AE or suspected adverse reaction is considered serious if, in the view of either the 
Investigator or Sponsor, it results in any of the following outcomes, at any dose:  
a. Results in death 
b. Is life-threatening 
• 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 inpatient hospitalization or prolongation of existing hospitalization 
• In general, hospitalization signifies that the patient has been admitted (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 outpatient 
setting. Complications that occur during hospitalization are AEs. 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 AE 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 persistent or significant disability/incapacity 
• 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 (eg, sprained ankle) which may interfere with or prevent everyday life 
functions but do not constitute a substantial disruption. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
42 
e. 
Is a congenital anomaly/birth defect 
f. 
Other situations: 
• Medical or scientific judgment should be exercised by the Investigator in deciding 
whether SAE reporting is appropriate in other situations such as significant medical 
events that may jeopardize the patient or may require medical or surgical intervention to 
prevent one of the other outcomes listed in the above definition. These events should 
usually be considered serious. 
o Examples of such events include invasive or malignant cancers, intensive treatment 
for allergic bronchospasm, blood dyscrasias, convulsions or development of 
intervention dependency or intervention abuse. 
9.4.1.3. 
Classification of an AE 
9.4.1.3.1. SEVERITY OF EVENT 
The severity (intensity) of an AE is to be graded by the Investigator according to CTCAE 
version 5.0 (CTCAE, 2017). 
General rules are as follows: 
1 Mild: asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated. 
2 Moderate: minimal, local, or noninvasive intervention (eg, packing, cautery) 
indicated; limiting age-appropriate instrumental activities of daily living (ADL). 
3 Severe or medically significant but not immediately life-threatening; hospitalization 
or prolongation of hospitalization indicated; disabling; limiting self-care ADL. 
4 Life-threatening consequences: urgent intervention indicated (SAE). 
5 Death related to AE (SAE). 
9.4.1.3.2. RELATIONSHIP TO STUDY TREATMENT (ASSESSMENT OF CAUSALITY) 
All AE/SAEs must have their relationship to study treatment/interventions and study procedures 
assessed by the clinician who examined and evaluated the patient based on temporal relationship 
and his/her clinical judgment. In a clinical study, the study product must always be suspect. 
Investigators will be asked to grade each AE/SAE as either related (a reasonable possibility of a 
relationship) or unrelated. 
A “reasonable possibility” of a relationship conveys that there are facts, evidence, and/or 
arguments to suggest a causal relationship, rather than a relationship cannot be ruled out. 
Alternative causes, such as underlying disease(s), concomitant therapy, and other risk factors, as 
well as the temporal relationship of the event to study treatment administration will be 
considered and investigated. 
The Investigator is instructed to also consult the IB in his/her assessment. 
For each collected reportable AE/SAE, the Investigator is instructed to document in the medical 
notes that he/she has reviewed the AE/SAE and has provided an assessment of causality. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
43 
There may be situations in which an SAE has occurred, and the Investigator has minimal 
information to include in the initial report to the Sponsor’s Designee (via electronic data 
capture (EDC)/eCRF transmission). However, it is very important that the Investigator always 
make an assessment of causality for every event before the initial transmission of the SAE data 
to the Sponsor’s Designee (via EDC/eCRF transmission). 
The Investigator may change his/her opinion of causality in light of follow-up information and 
send an SAE follow-up report with the updated causality assessment. 
9.4.1.3.3. EXPECTEDNESS 
The Sponsor will be responsible for determining whether an AE is expected or unexpected. An 
AE will be considered unexpected if the nature, severity, or frequency of the event is not 
consistent with the risk information previously described for the study treatment. 
An Unexpected Adverse Drug Reaction (UADR) is any noxious and unintended response that is 
related to the administration of an IP that has not been reported as expected in the IB (reference 
safety information for this study), either from previous clinical studies or the nonclinical studies. 
A Suspected Unexpected Serious Adverse Reaction (SUSAR) is any UADR that at any dose also 
meets the criteria for SAE. 
9.4.2. 
Time Period and Frequency for Collecting AE and SAE Information 
The occurrence of an AE or SAE may come to the attention of study personnel during study 
visits and interviews of a study patient presenting for medical care, or upon review by a study 
monitor. 
Adverse events will be collected from the signing of the ICF until completion of the 3-month 
Visit (Section 1.3). Information will be captured on the appropriate eCRF including event 
description, date of onset, clinician’s assessment of severity, relationship to study treatment and 
study procedure (assessed only by those with the training and authority to make a diagnosis), and 
date of resolution/stabilization of the event. All collected reportable AEs occurring while on 
study must be documented appropriately. All collected AEs will be followed to adequate 
resolution/stabilization. 
If the study patient’s condition deteriorates at any time during the study, it will be recorded as an 
AE. AEs reported from the time of study treatment administration will be considered as 
treatment-emergent adverse events (TEAEs). 
Changes in the severity of an AE will be documented to allow an assessment of the duration of 
the event at each level of severity to be performed. AEs characterized as intermittent require 
documentation of onset and duration of each episode. 
At study visits per the SoA (Section 1.3), the Investigator and/or designee should inquire about 
the occurrence of AE/SAEs since the last visit. The Investigator or designated investigational 
staff member should record the start date of all collected reportable events. Events will be 
followed for outcome information until resolution or stabilization and the dates of outcome must 
be recorded. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
44 
All SAEs are to be recorded and reported to the Sponsor immediately and under no 
circumstance should this exceed 24 hours. The Investigator should submit any updated SAE 
data to the Sponsor within 24 hours of it being available. 
Investigators are not obligated to actively seek information on AEs or SAEs after conclusion of 
the study participation. However, if the Investigator learns of any SAE, including a death, at any 
time after a patient has been discharged from the study, and he/she considers the event to be 
reasonably related to the study treatment or study participation, the Investigator must promptly 
notify the Sponsor within 24 hours. 
9.4.3. 
Method of Detecting AEs and SAEs 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the patient is the preferred method to inquire about 
AE occurrences. 
9.4.4. 
Follow-up of AEs and SAEs 
After the initial collected AE/SAE report, the Investigator and/or designee is required to 
proactively follow each patient at subsequent visits/contacts. All SAEs will be followed until 
resolution, stabilization, the event is otherwise explained, or the patient is lost to follow-up (as 
defined in Section 8.3). Further information on follow-up procedures is provided in Section 9.4.6. 
9.4.5. 
Regulatory Reporting Requirements for SAEs 
Each patient must be given a patient card containing details of the contact person at the site 
he/she should contact in case any unusual or serious signs or symptoms develop after treatment. 
Where required, patients will be examined at the center and will be clinically monitored until 
they recover. 
Expedited reporting to the Sponsor is required in the following conditions: 
1. Any SAE and follow-up SAE report, if required 
2. Death of study patient 
3. Pregnancy and outcome of the pregnancy 
The Investigator must inform the Sponsor/Sponsor Designee about the above by completing and 
submitting the SAE/Death or Pregnancy eCRF within 24 hours after its occurrence first came to 
his/her knowledge. 
Prompt notification by the Investigator to the Sponsor of an SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of patients and the safety of a study 
treatment under clinical investigation are met. 
The Sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study treatment under clinical investigation. The 
Sponsor will comply with country-specific regulatory requirements relating to safety reporting to 
the regulatory authority, IRB/IEC, and Investigators. 
An Investigator who receives an Investigator safety report describing an SAE or other specific 
safety information (eg, summary or listing of SAEs) from the Sponsor will review and then file it 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
45 
along with the Investigator File and will notify the IRB/IEC, if appropriate according to local 
requirements. 
Investigator safety reports must be prepared by the Sponsor for SUSARs according to local 
regulatory requirements and Sponsor policy and forwarded to Investigators as necessary. 
9.4.6. 
Serious Adverse Event Reporting 
The Investigator will immediately report to the Sponsor any SAE, whether or not considered 
study treatment-or study procedure related, including those listed in the protocol or IB and must 
include an assessment of whether there is a reasonable possibility that the study treatment or 
study procedure caused the event.  
All SAEs will be followed until satisfactory resolution or until the Investigator deems the event 
to be chronic or the patient is stable. Other supporting documentation of the event may be 
requested by the Sponsor or Sponsor’s Designee and should be provided as soon as possible. 
The Sponsor will be responsible for notifying the Food and Drug Administration (FDA) of any 
unexpected fatal or life-threatening suspected adverse reaction as soon as possible, but in no case 
later than 7 calendar days after the Sponsor’s initial receipt of the information. In addition, the 
Sponsor must notify FDA and all participating Investigators in an Investigational New Drug 
safety report of potential serious risks, from clinical studies or any other source, as soon as 
possible, but in no case later than 15 calendar days after the Sponsor determines that the 
information qualifies for reporting. 
9.4.6.1. 
SAE Reporting Instructions 
The Investigator must inform the Sponsor within 24 hours of becoming aware of an SAE (or 
updated SAE information) by completing and submitting the SAE/Death or Pregnancy eCRF. 
It is not acceptable for the Investigator to send photocopies of the patient’s medical records to the 
Sponsor or designee in lieu of completion of the SAE/Death eCRF. 
There may be instances when copies of medical records for certain cases are requested by 
regulatory or other agencies. In this case, all patient identifiers, with the exception of the patient 
number, will be redacted on the copies of the medical records before submission to the Sponsor 
or designee. 
If a site receives a report of a new SAE from a study patient or receives updated data on a 
previously reported SAE when the electronic data capture tool has been taken off-line or is 
unavailable, then the site can report this information on a paper SAE form to the Sponsor (or 
designee) or Medical Monitor by email or telephone within 24 hours.  
Initial notification via telephone does not replace the need for the Investigator to complete and 
sign the SAE data collection tool within the designated reporting time frames. 
The following is the contact information for SAE reporting.

9.4.7. 
Pregnancy 
For any female patient who becomes pregnant while participating in the study, the Investigator 
shall immediately discontinue study treatment and ensure expedited reporting of the event within 
24 hours (Section 9.4.5). The pregnancy will be followed to term and the outcome reported. 
While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy for medical reasons will be reported as an AE or SAE. 
Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs and will be reported as such. 
The patient/pregnant female partner will be followed to determine the outcome of the pregnancy. 
The Investigator will collect follow-up information on the patient/pregnant female partner and 
the neonate, and the information will be forwarded to the Sponsor. 
Any post-study pregnancy-related SAE considered reasonably related to the study treatment by 
the Investigator will be reported to the Sponsor as described in Section 9.4.5. While the 
Investigator is not obligated to actively seek this information in former study patients/pregnant 
female partner, he or she may learn of an SAE through spontaneous reporting. 
9.4.8. 
Disease-Related Events and/or Disease-Related Outcomes Not Qualifying as 
AEs or SAEs 
Not applicable. 
9.4.9. 
AESIs 
In this study, AESIs will be monitored on an ongoing basis through a regular review of adverse 
event listings. There are no requirements for the Investigator to make determination of AESIs 
and Investigators are to report all AEs in a consistent manner as described in Section 9.4.2.  
The list of AESIs is based on the most current safety profile of UGN-102 within the overall 
clinical development program and through ongoing review of emerging safety data. 
Current known AESIs include: 
• Allergic reaction to mitomycin (CTCAE Grade 3 or 4) 
• Voiding interruption due to urethral/penile edema (unrelated to prostatic hypertrophy) 
• Indication of bone marrow suppression 
• LUTS (CTCAE Grade 3 or 4)

Statistical Considerations 
10.1. 
Statistical Hypotheses 
The primary objective of this study is to evaluate the feasibility of home instillation of UGN-102 
for treatment of patients with LG IR NMIBC. Analyses are descriptive and exploratory in nature 
and no formal hypothesis will be tested.  
10.2. 
Sample Size Determination 
The sample size of this study (approximately 10 patients) is based on feasibility. 
10.3. 
Analysis Set 
The Safety Analysis Set that includes all patients who received any dose of UGN-102 will serve 
as the primary population for the analyses of safety and efficacy data in this study. 
10.4. 
Statistical Analyses 
10.4.1. 
General Considerations 
All measured variables and derived parameters will be listed individually and, if appropriate, 
tabulated using descriptive statistics. For categorical variables, summary tables will be provided 
giving sample size, absolute and relative frequency, and 95% CI for proportions using the exact 
approach. For continuous variables, summary tables will be provided giving sample size, 
arithmetic mean, standard deviation, coefficient of variation (if appropriate), median, minimum 
and maximum, percentiles, and 95% CI for means of variables as appropriate.  
10.4.2. 
Primary Endpoint(s) 
The primary endpoint is to assess the feasibility of home instillation of UGN-102 by 
• Rate of home instillation discontinuations 
• Feedback questionnaires from patients, home health professional, and investigator(s) 
• Safety profile of UGN-102 as assessed through standard clinical and laboratory tests 
(hematology and chemistry, urinalysis, physical examination, vital sign measurements, 
diagnostic tests, etc.) and through the collection of reports of adverse events (AEs) and 
serious adverse events (SAEs) including AEs of special interest. 
Home Instillation Discontinuations 
Descriptive statistics will be used to summarize proportion of patients discontinuing the home 
instillations. The frequency and the percentages will be presented. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
49 
Feedback Questionnaire 
Patient questionnaire 
Patients will be asked to rate their home instillation experience such as comfort, safety/concerns, 
communication, preference compared to office instillation and overall experience at each home 
instillation visit after the instillation is completed. A trend in their responses will be measured 
descriptively. Patients’ home instillation recommendations will also be collected and 
summarized descriptively at the 3-month Visit/EOS or ET Visit (Appendix A). 
Home health professional questionnaire 
Home health professionals will also be asked to complete a set of questionnaires after each home 
instillation visit. Data will be summarized descriptively (Appendix B). 
Investigator questionnaire 
Investigators will be asked to provide their feedback for each patient based on the experiences of 
the patient and the home health professional(s) at the 3-month Visit/EOS or ET Visit 
(Appendix C). 
Feasibility of home instillation will be assessed based on the totality of the data. 
Adverse Events 
The incidence of TEAEs (new or worsening from baseline) will be summarized by system organ 
class and or preferred term (PT), severity (based on CTCAE grades), type of AE, relation to 
study treatment. 
Deaths reportable as SAEs and non-fatal SAEs will be listed by patient and tabulated by type of 
adverse event. 
AESIs will be considered. A comprehensive list of reported AE terms based on clinical review 
will be used to identify Medical Dictionary for Regulatory Activities (MedDRA) PTs for each of 
the AESI categories. For some events, several AE preferred terms may be ‘collapsed.’ The list of 
terms to be used for each category of adverse events of interest may be based on the Safety 
Review Team (SRT) agreements in place at the time of reporting. The SRT agreements are based 
on a review of the MedDRA dictionary. 
Summaries of the number and percentage of patients with these events will be provided for each 
type of events. Further details will be provided in the statistical analysis plan (SAP). 
Clinical Laboratory Data 
Analyses of safety laboratory data will be performed for all collected laboratory parameters. 
Laboratory data will be graded according to CTCAE version 5.0 (CTCAE, 2017), if applicable. 
In some cases (eg, white blood cell differentials), the lower limits of normal ranges used in 
CTCAE definition may need to be replaced by a clinically meaningful limit expressed in 
absolute counts. 
For laboratory tests where grades are not defined by CTCAE, results will be graded by the 
low/normal/high classifications based on laboratory normal ranges. 
Data will be summarized and/or listed separately for hematology, biochemistry, and urinary 
laboratory tests as appropriate.

Physical Examination 
Full physical examination will be performed at Screening only. Urology oriented physical 
examination will be performed at Screening, at the first treatment visit and at the EOS Visit (or 
ET Visit). Details are provided in Section 1.3 and Section 9.3.1. Any clinically relevant changes 
of urological physical examination will be recorded on the AE Sections of the eCRF and 
reported with AEs as described above. 
Vital Signs 
Table with descriptive statistics at baseline and post-baseline time points will be summarized. 
Patients exhibiting clinically notable vital sign abnormalities may be listed. 
10.4.3. 
Secondary Efficacy Endpoint(s) 
CR Rate at 3-month Visit (Disease Assessment) 
CR rate is defined as the proportion of patients who achieved CR at the 3-month disease 
assessment as determined by cystoscopy, for cause biopsy, and urine cytology. If a patient dies 
or terminates the study prior to the 3-month visit, that patient will be considered as a non-CR and 
will be included in the denominator to calculate the CR rate. CR rate will be presented along 
with Exact 95% Clopper-Pearson CIs. 
10.4.4. 
Other Analysis 
Additional exploratory endpoints may be added in the SAP.

ICH guidelines, Health Insurance Portability and Accountability Act requirements, where 
applicable, and the IRB/IEC or study center. 
11.1.2.4. Consent Procedures and Documentation 
Informed consent is a process that is initiated prior to the individual’s agreeing to participate in 
the study and continues throughout the individual’s study participation. Consent forms will be 
IRB-approved, and the patient will be asked to read and review the document. The Investigator 
or his/her representative will explain the nature of the study to the patient or their legally 
authorized representative and answer all questions regarding the study. A verbal explanation will 
be provided in terms suited to the patient’s comprehension of the purposes, procedures, and 
potential risks of the study and of their rights as research patients. Patients will have the 
opportunity to carefully review the written consent form and ask questions prior to signing. The 
patients should have the opportunity to discuss the study with their family or surrogates or think 
about it prior to agreeing to participate. 
Patients must be informed that their participation is voluntary and that they may withdraw from 
the study at any time, without prejudice. Patients or their legally authorized representative 
defined as per the applicable country-specific regulations will be required to sign a statement of 
informed consent prior to any procedures being done specifically for the study. 
The informed consent process will be conducted and documented in the source document 
(including the date), and the form signed, before the patient undergoes any study-specific 
procedures. The rights and welfare of the patients will be protected by emphasizing to them that 
the quality of their medical care will not be adversely affected if they decline to participate in 
this study. The authorized person obtaining the informed consent must also sign the ICF.  
Patients must be re-consented to the most current version of the ICF(s) during their participation 
in the study.

The patient must be informed that his/her medical/pharmacy records and records may be 
examined by Clinical Quality Assurance auditors or other authorized personnel appointed by the 
Sponsor, by appropriate IRB/IEC members, and by inspectors from regulatory authorities. The 
clinical investigative site will permit access to such records. 
Patient confidentiality and privacy is strictly held in trust by the participating Investigators, their 
staff, and the Sponsor and their interventions. This confidentiality is extended to cover testing of 
biological samples and genetic tests in addition to the clinical information relating to patients. 
Therefore, the study protocol, documentation, data, and all other information generated will be 
held in strict confidence. No information concerning the study, or the data will be released to any 
unauthorized third party without prior written approval of the Sponsor.  
All research activities will be conducted in as private a setting as possible. 
The study patient’s contact information will be securely stored at each clinical site for internal 
use during the study. At the end of the study, all records will continue to be kept in a secure 
location for as long a period as dictated by the reviewing IRB, institutional policies, or Sponsor 
requirements. 
11.1.4. 
Data Review Committee 
No data review committee will be implemented for this study. 
11.1.5. 
Dissemination of Clinical Study Data 
Data collected for this study will be analyzed and stored by the Sponsor. After the study is 
completed, the de-identified, archived data will be transmitted to and stored by the Sponsor, for 
use by other researchers including those outside of the study. Permission to transmit data to the 
Sponsor will be included in the informed consent.  
When the study is completed, access to study data and/or samples will be provided through the 
Sponsor. 
11.1.6. 
Safety Oversight 
Safety oversight will be under the direction of the Sponsor. Safety will be assessed throughout 
the course of the study by the Sponsor Safety Review Team. 
11.1.7. 
Clinical Monitoring 
The Sponsor will perform on-site monitoring visits as frequently as necessary, depending on 
recruitment frequency at each site. The monitor will record dates of the visits in an investigative 
site visit log that will be kept at the site. Remote monitoring of patient Screening data will be 
performed on all patients, to ensure eligibility. The first post-initiation visit will be made as soon 
as possible (approximately 2-3 weeks) after enrollment has begun. At these visits, the monitor 
will compare the data entered into the eCRF with the hospital or clinic records (source 
documents). The nature and location of all source documents will be identified to ensure that all 
sources of original data required to complete the eCRF are known to the Sponsor and 
investigational staff and are accessible for verification by the Sponsor site contact. If electronic 
records are maintained at the investigational site, the method of verification must be discussed 
with the investigational staff. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
54 
Direct access to source documentation (medical records) must be allowed for verifying that the 
data recorded in the eCRF are consistent with the original source data. Findings from this review 
of eCRFs and source documents will be discussed with the investigational staff. The Sponsor 
expects that, during monitoring visits, the relevant investigational staff will be available, the 
source documentation will be accessible, and a suitable environment will be provided for review 
of study-related documents. The monitor will meet with the Investigator on a regular basis during 
the study to provide feedback on the study conduct. Further details of clinical site monitoring 
including handling of noncompliance issues and monitoring techniques (central, remote, or on-
site monitoring) will be provided in a Study Monitoring Plan (SMP). The SMP will describe in 
detail who will conduct the monitoring, at what frequency monitoring will be done, at what level 
of detail monitoring will be performed, and the distribution of monitoring reports. 
Independent audits may be conducted by representatives of the Sponsor’s clinical quality 
assurance department or their designee to ensure that monitoring practices are performed 
consistently across all participating sites and that monitors are following the SMP. 
11.1.8. 
Data Quality Assurance 
All patient data relating to the study will be recorded on eCRF. The Investigator is responsible 
for verifying that data entries are accurate and correct by electronically signing the CRF. 
Guidance on completion of eCRFs will be provided in the CRF Completion Guidelines. 
The Investigator must permit study-related monitoring, audits, IRB/IEC review, and regulatory 
agency inspections and provide direct access to source data documents. 
Quality tolerance limits (QTLs) or quality control (QC) checks identify systematic issues that 
can impact patient safety and/or reliability of study results. These QTLs or QC checks (ie, data 
QC checks) will be implemented for the EDC. Any missing data or data anomalies will be 
communicated to the sites for clarification/resolution. 
Following written Standard Operating Procedures, the monitors will verify that the clinical study 
is conducted, data are generated, and biological specimens are collected, documented 
(ie, recorded), and reported in compliance with the protocol, ICH GCP, and applicable regulatory 
requirements (eg, Good Laboratory Practices).  
The Sponsor or designee is responsible for the data management of this study including quality 
checking of the data. 
The Sponsor assumes accountability for actions delegated to other individuals (eg, Contract 
Research Organizations). 
Study patient research data, which are for purposes of statistical analysis and scientific reporting, 
will be transmitted to and stored by the Sponsor. This will not include the patient’s contact or 
identifying information. Rather, individual patients and their research data will be identified by a 
unique study identification number. The study data entry and study management systems used by 
clinical sites and by the Sponsor’s research staff will be secured and password-protected. At the 
end of the study, all study databases will be de-identified and archived by the Sponsor.

11.1.9. 
Data Handling and Record Keeping 
11.1.9.1. Data Collection and Management Responsibilities  
This study will use an EDC system; the designated Investigator staff will enter the data required 
by the protocol into the eCRFs. The eCRFs are built using fully validated, secure, web-enabled 
software that conforms to 21 CFR Part 11 requirements. Investigator site staff will not be given 
access to the EDC system until they have been trained. Automatic validation programs check for 
data discrepancies in the eCRFs and allow modification or verification of the entered data by the 
Investigator staff. 
Data collection is the responsibility of the clinical study staff. The Investigator is responsible for 
ensuring the accuracy, completeness, legibility, and timeliness of the data reported. It is the 
Sponsor’s expectation that data required by the protocol will be entered by the clinical site staff 
in a timely manner according to provided guidance. 
Clinical data will be entered directly from the source documents. All source documents should 
be completed in a neat, legible manner to ensure accurate interpretation of data and if applicable, 
signed or initialed and dated. 
Hard copies of the study visit worksheets may be provided for use as source document 
worksheets for recording data for each patient enrolled in the study. Data recorded in the eCRF 
derived from source documents should be consistent with the data recorded on the source 
documents. 
Data collected at home health visits will be recorded by the home health professional in the EDC.  
11.1.9.2. Study Records Retention  
Study documents should be retained for a minimum of 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated marketing 
applications in an ICH region, or until at least 2 years have elapsed since the formal 
discontinuation of clinical development of the study treatment. These documents should be 
retained for a longer period, however, if required by local regulations or institutional policies. No 
records will be destroyed during the retention period without the written consent of the Sponsor, 
if applicable. It is the responsibility of the Sponsor to inform the Investigator when these 
documents no longer need to be retained. No records may be transferred to another location or 
party without written notification to the Sponsor. 
11.1.10. 
Protocol Deviations  
A protocol deviation is a departure from the study protocol and/or study related documents. The 
departure may be either on the part of the site or the patient and identified as site or patient 
deviations. As a result of deviations, corrective actions are to be developed by the site and 
implemented promptly. 
Protocol deviations related to study inclusion or exclusion criteria, conduct of the study, patient 
management or patient assessment should be addressed in study source documents and reported 
to the Sponsor. Protocol deviations must be submitted to the local or central IRB/IEC according 
to their guidelines. The site PI/study staff is responsible for knowing and adhering to their 
IRB/IEC requirements. 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
56 
11.1.11. 
Source Documents 
Source documents provide evidence for the existence of the patient and substantiate the integrity 
of the data collected. Source documents are filed at the Investigator’s site. 
Data entered in the eCRF that are transcribed from source documents must be consistent with the 
source documents or the discrepancies must be explained. The Investigator may need to request 
previous medical records or transfer records, depending on the study. Also, current medical 
records must be available. 
The Investigator must maintain accurate documentation (source data) that supports the 
information entered in the eCRF. 
Study monitors will perform ongoing source data verification to confirm that data entered into 
the eCRF by authorized site personnel are accurate, complete, and verifiable from source 
documents; that the safety and rights of patients are being protected; and that the study is being 
conducted in accordance with the currently approved protocol and any other study agreements, 
ICH GCP, and all applicable regulatory requirements. 
11.1.12. 
Study and Site Start and Closure 
First Act of Recruitment 
The study start date is the date on which the clinical study will be open for recruitment of 
patients. 
The first act of recruitment is the first site open and will be the study start date. 
Study/Site Termination 
The Sponsor or designee reserves the right to close the investigative site or terminate the study at 
any time for any reason at the sole discretion of the Sponsor. Investigative sites will be closed 
upon study completion. An investigative site is considered closed when all required documents 
and study supplies have been collected and an investigative site closure visit has been performed. 
The Investigator may initiate investigative site closure at any time, provided there is reasonable 
cause and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of an investigative site by the Sponsor or Investigator may include 
but are not limited to: 
For study termination: 
• Discontinuation of further study treatment development 
• Determination of unexpected, significant, or unacceptable risk to patients 
• Demonstration of efficacy that would warrant stopping 
• Determination that the primary endpoint has been met 

CONFIDENTIAL 
Protocol BL010 version 1.0 
 
57 
For site termination: 
• Failure of the Investigator to comply with the protocol, the requirements of the IRB/IEC 
or local health authorities, the Sponsor's procedures, or GCP guidelines 
• Inadequate or no recruitment (evaluated after a reasonable amount of time) of participants 
by the Investigator 
• Total number of participants included earlier than expected 
If the study is prematurely terminated or suspended, the Sponsor shall promptly inform the 
Investigators, the IRBs/IECs, the regulatory authorities, and any contract research 
organization(s) used in the study of the reason for termination or suspension, as specified by the 
applicable regulatory requirements. The Investigator shall promptly inform the patient and 
should assure appropriate patient therapy and/or follow-up. 
The study may resume once concerns about safety, protocol compliance, and data quality are 
addressed, and satisfy the Sponsor, IRB, and/or FDA. 
11.1.13. 
Publication Policy 
The results of this study may be published or presented at scientific meetings. If this is foreseen, 
the Investigator agrees to submit all manuscripts or abstracts to the Sponsor before submission. 
This allows the Sponsor to protect proprietary information and to provide comments. 
The Sponsor will comply with the requirements for publication of study results. In accordance 
with standard editorial and ethical practice, the Sponsor will generally support publication of 
multicenter studies only in their entirety and not as individual site data. In this case, a 
coordinating Investigator will be designated by mutual agreement. 
Authorship will be determined by mutual agreement and in line with International Committee of 
Medical Journal Editors authorship requirements. 
11.1.14. 
Conflict of Interest Policy 
The independence of this study from any actual or perceived influence, such as by the 
pharmaceutical industry, is critical. Therefore, any actual conflict of interest of persons who have 
a role in the design, conduct, analysis, publication, or any aspect of this study will be disclosed 
and managed. Furthermore, persons who have a perceived conflict of interest will be required to 
have such conflicts managed in a way that is appropriate to their participation in the design and 
conduct of this study. The Sponsor has established policies and procedures for all study group 
members to disclose all conflicts of interest and will establish a mechanism for the management 
of all reported dualities of interest.
