PROTOCOL SUMMARY
1.1
Synopsis 
Title:
A Phase 2b, Single-Arm, Multicenter Trial to Evaluate the Efficacy and 
Safety of UGN-1021 as Primary Chemoablative Therapy in Patients with 
Low Grade (LG) Non-Muscle-Invasive Bladder Cancer (NMIBC) at 
Intermediate Risk of Recurrence.
Study Description:

Trial TC-BC-12 is a prospective Phase 2b single-arm trial to 
evaluate the efficacy and safety of 6 weekly instillations of 
UGN-102 in patients with LG NMIBC.

All enrolled patients will undergo treatment with intravesical UGN-
102.

Approximately 60 patients with LG NMIBC who meet the 
inclusion/exclusion criteria will be enrolled in the trial.

Following a successful screening period, eligible patients will be 
enrolled in the study.

Eligible patients will receive 6 weekly intravesical instillations of 
UGN-102. The primary endpoint assessment (complete response 
[CR]) will take place 5 weeks 1 week after the last instillation 
(approximately 3 months after initiation of study treatment), at 
which time the patients will be evaluated for treatment response. 

Patients who achieve a CR will continue to be monitored monthly 
for safety, and will be assessed at 6, 9, and 12 months (±2 weeks) 
after the first instillation of UGN-102 for evidence of disease 
recurrence. Nonresponders (non-CR) will exit the study and 
continue with standard of care according to their treating physician.
Objectives:
Primary Objective: To evaluate the tumor ablative effect of UGN-102 in 
patients with LG NMIBC.
Secondary Objectives:
To evaluate the durability of response in patients with LG NMIBC who 
achieve CR at the 3 MONTH Visit
To evaluate the safety and tolerability of intravesical UGN-102 instillations 
in patients with LG NMIBC.
Additional Objective: 
To assess the pharmacokinetic profile of Mitomycin C (MMC) in plasma of 
a subset of patients treated with UGN-102.
Endpoints:
Primary Endpoint: CR rate for UGN-102 treatment in patients with LG 
NMIBC at the 3 MONTH Visit (3 months after the first instillation of 
UGN-102) as assessed by cystoscopy, with or without biopsy, and urine 
cytology. 
Secondary Endpoints:
1 UGN-102 was formerly known as VesiGel.

Efficacy: Durable complete response (DCR) rate: proportion of patients 
with no evidence of disease at 6, 9, and 12 months after the first instillation 
of UGN-102 in patients who achieved CR at the 3 MONTH Visit.
Safety: Frequency, severity, and types of adverse events (AEs), including 
AEs of special interest; changes from baseline in laboratory values and 
incidence of measurements defined as potentially clinically significant; and 
clinically meaningful changes in physical examination findings.
Tertiary/Exploratory Endpoints: 
Pharmacokinetic: The pharmacokinetic (PK) profile of the first MMC 
instillation in the blood will be examined in a subset of six patients.
Quality of Life (QoL): To examine patient reported outcome of health-
related quality of life
Study Population:
Patients who have been diagnosed with LG NMIBC, and determined to 
have intermediate risk of recurrence, defined as 1 or 2 of the following: 
multiple tumors, solitary tumor >3 cm, or recurrence (≥ 1 occurrence of LG 
NMIBC within 1 year of the current diagnosis). 
Phase:
Phase 2b
Description of 
Sites/Facilities 
Enrolling Patients:
This study will be conducted by appropriately trained urologists at 
approximately 30 sites in North America and Israel.
Description of Study 
Medication:
UGN-102 preparation for intravesical instillations, containing Mitomycin C 
(MMC) 80 mg and 60 mL UG-1 gel, in order to administer 75 mg MMC in 
a 56 mL instillation (1.33 mg mitomycin per mL).
Treatment duration: 6 instillations, administered once weekly over 6 weeks.
Study Duration:
Approximately 26 months (from first center initiated [FCI] until last patient 
last visit [LPLV]).
Patient Duration:
Approximately 13 months per patient (from enrollment through last visit).

INTRODUCTION
4.1
Study Rationale
Non-Muscle-Invasive Bladder Cancer
Urothelial cancer (UC) of the bladder is the second most common genitourinary malignancy, 
with almost 80,000 new cases diagnosed annually in the United States (US) and nearly 17,000 
deaths from the disease per year. Non-muscle-invasive bladder cancer (NMIBC) accounts for 
about 80% of all bladder cancers (Heney, 1992). Patients with NMIBC can be segmented into 
3 staging groups: patients with Ta tumors (70%), patients with T1 tumors (20%), and patients 
with carcinoma in situ (CIS) or Tis tumors (10%). Of these patients, approximately 70% have a 
tumor that is classified as low grade (LG), and approximately 30% have a tumor that is classified 
as high grade (HG). Ta and CIS tumors are limited to the urothelial layer, and T1 is limited to the 
lamina propria.
The standard treatment of NMIBC is transurethral resection of bladder tumor (TURBT) (Brausi, 
2002), often followed by adjuvant intravesical chemotherapy or immunotherapy (Hall, 2007). 
TURBT is associated with the typical risks of surgery including injury to the bladder and 
postoperative bleeding. Recurrence rates following standard of care (SoC) management range 
from 31% to 78% with the risk of progression to muscle invasion approaching 50% in patients 
with HG cancer (Sylvester, 2006). Tumor recurrence following TURBT can be attributed 
primarily to incomplete initial resection and, at least hypothetically, to tumor cell reimplantation 
following surgery (Brausi, 2002; Miladi, 2003, Anastasiadis, 2012). The effectiveness of 
intravesical therapy is limited by urine production, which results in drug dilution and periodic 
bladder emptying, and which limits the agent’s time on target (Audenet, 2013; Barlogie, 1980; 
De Bruijn, 1992; Deb, 2011; Eastham, 1993; Nozue, 1995a; Ozawa, 1988; Perry, 1992; Sadeghi, 
1998; Schmittgen, 1991; Slee, 1986; Walker, 1986; Wang, 2013, O’Donoghue, 2004).
Chemoablation represents an attractive alternative to surgical therapy. It could avoid the 
morbidity and expense of surgery and may offer a more rational therapeutic approach to UC, 
which is generally multifocal and refractory to focal ablative interventions. Preliminary evidence 
documents the ablative capabilities of aqueous Mitomycin C (MMC), which has been applied 
successfully to the primary management of small UCs (Bono, 1996; Bracken, 1980; Brausi, 
1998; Colombo, 2001; Ost, 2015; Hamdy, 1993; Harrison, 1983; Hetherington, 1987; Maffezzini, 
1996; Mishina, 1975; Soloway, 1985.) 
UGN-102
The Sponsor performed a Phase 2 study (Study TAS-4M-CS-002) in 65 evaluable patients with 
LG NMIBC and showed that UGN-102 therapy is associated with a complete response (CR) rate 
of 86% and significant durability of response (77% recurrence free survival at 12 months) in 
those patients achieving an initial CR. Based on this initial experience, the Sponsor proposes to 
conduct a Phase 2b UGN-102 trial in the US to corroborate the data provided by the European 
Trial.

Study TC-BC-12
This study is a prospective, Phase 2b, single-arm, open-label trial to evaluate the efficacy and 
safety of UGN-102 75 mg given once weekly intravesically, for a total of 6 doses, in the 
treatment of patients with LG NMIBC at intermediate risk of recurrence. 
4.2
Background 
UGN-102 is a reverse thermal hydrogel formulated with MMC. The product is specifically 
formulated to achieve a liquid state at 4C and to transition to a water-soluble gel at body 
temperature. The advantage of delivering Mitomycin to the urinary bladder using UGN-102 relies 
on preclinical and clinical literature documenting that concentration and dwell time correlate 
directly with the therapeutic efficacy of MMC when used to treat UC (Barlogie, 1980; Slee, 
1986; Walker, 1986; Ozawa, 1988; Perry, 1992; Nozue, 1995b; Sadeghi, 1998).
MMC functions as a bifunctional or trifunctional alkylating agent. It is most sensitive in the late 
G1 and early S phases, but overall is considered cell cycle phase non-specific (Badalament, 
1997). The cell killing induced by MMC, as well as by other topical chemotherapy drugs, is 
proportional to the duration of exposure and to concentration (Serreta, 2008; DeBruijn, 1992; 
Sadeghi, 1998; Barlogie, 1980; Nozue, 1995b; Schmittgen, 1991; Ozawa, 1988; Walker, 1986; 
Slee, 1986; Giesbers, 1989). 
UGN-102 Investigational Product
UGN-102 is provided by UroGen Pharma as a kit containing 2 vials of 40 mg MMC for injection, 
one 60 mL vial of UG-1 (UG-1 sterile hydrogel), 3 × 30 mL sterile syringes, and sterile syringe 
stoppers. The proprietary hydrogel, UG-1, allows for a sustained release of MMC at the target 
site of administration, resulting in prolonged exposure of the tumor cells to MMC, where it can 
exert a chemical ablative effect.
Preclinical studies of UGN-102 performed by UroGen demonstrated limited systemic absorption 
of MMC. In a porcine model, all MMC plasma concentrations were found to be substantially 
below 400 ng/mL, which is the drug concentration associated with myelosuppression (Dalton, 
1991). In clinical studies, systemic levels of MMC were low and well within the range 
considered safe. Systemic toxicity following intravesical therapy is uncommon because of the 
limited absorption of MMC. Myelosuppression occurs in <1% of patients (de Bruijn, 1992). 
Investigators have reported that extended dwell times appear safe in humans (de Bruijn, 1992).
For further details of the preclinical and clinical studies conducted with UGN-102, refer to the 
Investigator Brochure for UGN-101 (MitoGel) and UGN-102 (VesiGel).
4.3
Risk/Benefit Assessment  
4.3.1 Known Potential Risks 
Toxicity Associated with Systemic Absorption/Local Irritation
Although literature review did not demonstrate any side effects associated with the systemic 
absorption when MMC was administered topically, bone marrow toxicity (thrombocytopenia and 
leukopenia) and bladder toxicity are considered possible risks for patients. The complete blood 
count (CBC) and renal and liver function tests will be checked regularly during the treatment 
period. In case of clinically significant abnormalities, the investigator will continue to follow the 
abnormal parameter until resolution, stabilization, or otherwise managed.

Allergic Response to MMC
MMC bladder instillations have been shown to cause allergic reactions in various degrees of 
toxicity in treated patients. Toxicities were found to be manageable most of the time by treating 
the patients with antihistamine drugs prior to and after the treatment, and with systemic steroids 
as needed. Signs of an allergic response will be closely monitored during the trial.
Cystitis
Cystitis and other lower urinary tract symptoms (LUTS) may develop. Urine tests, including 
urine culture and urinalysis, will be checked regularly during the trial to exclude urinary 
infection. Any symptoms will be treated by the Investigator according to local practice. 
All of the symptoms described above are all well known in relation to standard MMC 
instillations and are not exclusive to UGN-102. 
Currently, the SoC for NMIBC is TURBT. This surgical procedure has its own potential risks 
such as bladder perforation resulting in MMC leak, bladder scarring, and decreased bladder 
capacity; urinary retention requiring catheterization; and the need for anesthesia. Moreover, 
during TURBT, tumor cells are released into the bladder cavity and may be seeded in denuded 
areas of the bladder where the urothelium is surgically interrupted. This is one of the reasons for 
the high rate of tumor recurrence and the need of immediate post-TURBT chemotherapy (usually 
MMC instillations). The high recurrence rate of NMIBC indicates that the current SoC is far from 
optimal. 
4.3.2 Known Potential Benefits 
The potential advantages of instillation of MMC in gel are as follows:

Sustained release of drug for up to 8 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 gel protects MMC from both breaking down in urine and being diluted by urine, 
which leads to longer stable chemotherapy concentration levels.
These characteristics of UGN-102 (MMC+UG-1) are expected to improve MMC treatment 
efficacy and provide an alternative mode of ablation for NMIBC, which may be simpler and 
potentially better tolerated than current treatment modalities.
4.3.3 Assessment of Potential Risks and Benefits 
The potential benefits exceed the risks observed so far in the development program. Since the 
risks are similar to those observed with intravesical MMC alone, and the expected benefits are to 
improve MMC’s therapeutic efficacy and to expand its use, the overall risk:benefit ratio at this 
stage supports continued development of UGN-102.

STUDY DESIGN 
6.1
Overall Design
This study is a prospective, proof of concept, open-label, single-arm, multicenter Phase 2b trial 
designed to assess the efficacy and safety of UGN-102 treatment instilled in patients diagnosed 
with LG NMIBC including newly-diagnosed patients, and determined to have intermediate risk 
of progression, defined as 1 or 2 of the following: multiple tumors, tumors >3 cm, or recurrence 
(≥ 1 occurrence of LG NMIBC within 1 year of the current diagnosis). Eligible patients will be 
treated with 6 weekly instillations of UGN-102.

Upon signing of informed consent, patients will undergo a Screening Visit for eligibility 
evaluation.  The screening period is 2 weeks if the patient’s cold cup biopsy to confirm LG tumor 
is historic (taken within 6 weeks of the screening visit) or 4 weeks if the patient’s cold cup biopsy 
to confirm LG tumor is current (taken at the screening visit). 
Starting at the Baseline Visit (Day 1), eligible patients will be treated with UGN-102 once 
weekly for a total of 6 doses; the UGN-102 concentration to be used in this trial will be 1.33 mg 
MMC per 1mL. The volume of UGN-102 to be instilled will be 56 mL (75 mg of MMC). 
The ablative effect of UGN-102 will be evaluated at the 3-month assessment, which will take 
place 5 weeks ±1 week after the last weekly instillation (3 months after initiation of study 
medication). Response will be determined based on visual evaluation by cystoscopy (appearance, 
number, and size of the lesions) and, if there are remaining lesions, by histopathology of the 
remaining lesions. CR is defined as having no detectable disease (NDD) and will be assessed 
visually during cystoscopy and also upon urine cytology. In the event that the investigator is not 
sure, and there is suspect tissue, a small biopsy will be taken from the suspect tissue to confirm 
CR in addition to cystoscopy and urine cytology. Patients who achieve a CR will continue to 
have monthly telephone contacts to document any adverse events and changes in concomitant 
medications  and will be assessed at 6, 9, and 12 months after the first instillation of UGN-102 
for evidence of disease recurrence. The group of patients considered nonresponders (non-CR) 
will discontinue the study and continue with SoC according to their treating physician.
Safety will be determined based on physical examination, laboratory assessments, and a review 
of AEs. All safety data will be reviewed on an ongoing basis, including close review and follow 
up of any unexpected AE related to UGN-102 and qualified per National Cancer Institute (NCI) 
Common Terminology Criteria for Adverse Events (CTCAE) as Grade 3 or 4.
6.2
Scientific Rationale for Study Design
The single-arm, noncomparative design was chosen to confirm the results of a previous study 
(Study TAS-4M-CS-002), which indicated that a dose regimen of 6 weekly instillations of 
UGN-102 75 mg was effective and well tolerated in patients with LG NMIBC. Based on data 
from an ongoing Phase 3 trial in a similar indication, UTUC, monthly maintenance treatments do 
not appear to have a meaningful effect on durability of response in those patients who were CR at  
the 3-month assessment (primary endpoint). This study also aims to treat a slightly more 
challenging population: those at increased risk for recurrence. 
6.3
Justification for Dose
The UGN-102 dose of 75 mg was chosen based on both efficacy and tolerability. 
Study TAS-4M-CS-002 demonstrated numerically higher CR rates for the 75 mg dose than for 
the 37.5 mg dose. In Study TC-BC-10, 120 mg of UGN-102 had a similar response rate to 75 mg 
and a higher rate of AEs.
Although this is a single-arm, noncomparative study, patients who do not achieve CR after 
6 weekly instillations of UGN-102 75 mg will exit the study and be treated according to best 
practice according to their treating physician.

The clinical supplies storage area at the study site must be monitored by the site staff for 
temperature consistency with the acceptable storage temperature range as specified on the label. 
Documentation of temperature monitoring should be maintained and available for review.
8.2.4 Preparation
The UGN-102 preparation (UG-1 gel mixed with MMC) is stable for 48 hours at 25C (77F), 
with variation permitted between 15°C (59°F) and 30°C (86°F). Exposure to excessive heat (over 
40°C, 104°F) should be avoided. Up to 1 hour before administration, the admixture should be 
cooled down to between -3°C and +5°C in order to liquify the UGN-102. The elapsed cooling 
time must be documented from the point the mixture is prepared until it is instilled, which 
includes the length of time at room temperature, as well as length of time at a refrigerated 
temperature. 
8.2.5 Product Quality Complaint Handling
A Product Quality Complaint (PQC) is defined as any suspicion of a product defect related to 
manufacturing, labeling, or packaging; i.e., 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 or storage at the pharmacy, the 
investigator is responsible for notifying the Sponsor in writing using the PQC form about the 
defect/temperature deviation. Any written PQC report must be reported to the Sponsor by email 
to: qa@urogen.com.
ATTN: Quality Assurance
Reporting must be done upon first awareness, and the site should await the Sponsor’s decision 
regarding the drug’s validity prior to drug dispensing.
If the defect is combined with an SAE, the investigational staff must report the PQC to the 
Sponsor according to the SAE reporting timelines (refer to Section 10.4.6; Serious Adverse Event 
Reporting). The affected trial 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.
8.3
Measures to Minimize Bias: Randomization and Blinding
Not applicable; this is an open-label, single-arm study.
8.4
Study Medication Compliance
The study medication will be administered at specified treatment visits by properly trained study 
site staff members. Each drug administration will be documented in the patient’s file and eCRF.
8.5
Concomitant and Prohibited Therapy
For this protocol, a prescription medication is defined as a medication that can be prescribed only 
by a properly authorized/licensed clinician. Medications to be reported in the eCRF are 
concomitant prescription medications, over-the-counter medications, and supplements. Prohibited 
concomitant medications include systemic chemotherapy, intravesical chemotherapy, and 
immunotherapy for bladder cancer treatment including but not limited to BCG.
In cases of symptomatic UTI, the patient will be treated with a full course of antibiotics, and 
study medication will be postponed until resolution. In the case of asymptomatic bacteriuria, the 
use of prophylactic antibiotics and postponement of study medication is left to the discretion of 
the Principal Investigator (PI).
8.5.1 Rescue Medicine
Patients considered non-CR at the 3 MONTH Visit (Visit 7) will exit the study and will be 
treated according to best practice according to their treating physician.

STUDY MEDICATION DISCONTINUATION AND PATIENT 
DISCONTINUATION/WITHDRAWAL
9.1
Discontinuation of Study Medication
Discontinuation from study medication does not mean discontinuation from the study, and 
remaining study procedures should be completed as indicated by the study protocol. 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.
If a patient discontinues study medication during the treatment period or at any time prior to the 3 
MONTH Visit, the following unscheduled visit activities should be performed:

All 3 MONTH Visit (Visit 7) procedures should be conducted.

If the patient appears to have a CR (refer to Section 10.2.2), the patient has the option to 
continue participating in the follow-up assessments conducted at Months 6, 9, and 12 
(Visits 10, 13, and 16, respectively) to assess for disease recurrence and monthly 
telephone contacts for safety checks.

If patient agrees to complete the follow-up visits within the trial or agrees to continue to 
share information regarding his/her disease status, information collected during the 
follow-up care of the patient should be recorded in the eCRF.
9.2
Patient Discontinuation/Withdrawal from the Study
Patients in this trial are free to withdraw from participation in the study at any time.
An investigator may discontinue or withdraw a patient from the study for the following reasons:

Pregnancy

Significant study medication non-compliance

If any clinical AE, laboratory abnormality, or other medical condition or situation occurs 
such that continued participation in the study would not be in the best interest of the 
patient

Disease progression that requires discontinuation of the study medication

If the patient meets an exclusion criterion (either newly developed or not previously 
recognized) that precludes further study participation

Patient becomes unable to receive study medication for 4 weeks.

Patient is lost to follow-up (see section 9.3)
The reason for patient discontinuation or withdrawal from the study will be recorded on the 
eCRF. Patients who sign the informed consent form but do not receive the study medication may 
be replaced. Patients who sign the informed consent form, receive the study medication, and 
subsequently withdraw, or are withdrawn or discontinued from the study, will not be replaced.

9.3
Lost to Follow-Up
A patient will be considered lost to follow-up if he or she fails to return for 2 sequential 
scheduled visits and is unable to be contacted by the study 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.

Assessment of response will be based on the following:

Visual observation (cystoscopy)

Biopsy of remaining lesions, if applicable (non-CR or suspected tissue)

Voiding urine cytology
10.2.2 Evaluation of Response
Patient response will be evaluated according to the following criteria: 

CR: A patient will be considered to have had CR if there is NDD. To determine NDD, the 
following conditions should be fulfilled:
1. If visual assessment indicates no remaining tumors and urine cytology is negative, the 
patient has NDD and CR.  In the event that the bladder is free of tumor 
endoscopically, but the cytology is positive, the investigator is required to exclude 
urothelial carcinoma of the upper tract and occult carcinoma of the bladder or urethra. 
If   UTUC is confirmed, the patient will be considered as CR.
2. If any remaining lesions appear, even if they appear necrotic, the physician should 
biopsy the lesion(s). If a biopsy is taken from the necrotic lesion and found to be

Page 30 of 56

negative, the patient should be classified as having CR; if positive for cancer, the 
patient should be classified as non-CR.

Non-CR:
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 non-CR. Note that biopsy results showing PUNLMP are not considered 
cancer and in such cases the patient would be considered CR.

Recurrence: For patients with CR at the 3 MONTH Visit, recurrence will be assessed at 
Study Visit 10, Visit 13, and Visit 16.

If evidence of disease is identified, patients will be staged according to their local 
Investigator practice. Progression is defined as change in either stage according to the 
Tumor-Node-Metastases (TNM) classification or grade according to the 2004 World 
Health Organization (WHO) classification of tumors.
Since the patient is recruited into the trial as a patient with LG NMIBC (based on a small 
biopsy for LG confirmation), it is unlikely that the tumor will progress to HG during the 
6-week study medication period. 
10.2.3 Assessment of Tumor Progression
Diagnosis of bladder cancer at the 3 MONTH Visit with an increase in stage or grade compared 
to baseline will be tracked; however, it likely does not represent true progression for the 
following reason:

The overall risk of progression for patients with LG papillary NMIBC at intermediate risk 
of recurrence ranges from 5 to 20% at 1 and 5 years (Sylvester, 2006). A 12-week 
interval, during which the patient is exposed to MMC treatment, is not considered long 
enough for progression to occur in patients with non-invasive UC.
Upstaging/upgrading detected at the 3-MONTH Visit will be recorded, and the overall incidence 
will be compared with that reported in the literature.
10.2.4 Assessment of Tumor Recurrence
Follow-up will be conducted in patients who were defined as having CR at the 3 MONTH Visit.
Starting with the first follow-up visit (Study Visit 10, Month 6) and continuing at Visit 13 and 16 
(Months 9 and 12), information regarding disease status based on cystoscopy, cytology, and 
biopsy (when applicable) should be recorded. If a patient is defined as having recurrence, 
complete documentation should be obtained. If a patient has a positive urine cytology and/or a 
positive biopsy for cancer, they are considered as having urothelial cell cancer with likely 
recurrence. If urine cytology is positive but the biopsy is negative, the patient should be evaluated 
for the presence of UTUC, either by repeat CT Urogram or by retrograde pyelogram. In cases 
where CT Urogram or retrograde pyelogram are contraindicated, MRI may be performed. If the 
patient is positive for UTUC that was not present at baseline and there is no evidence of tumor 
within the bladder, this is considered new disease and the patient remains a CR for their NMIBC.

10.2.5 Pathological Evaluation
Biopsies and urine cytology specimens obtained at screening or any other visit should be 
evaluated by the local institutional pathologist. 
10.3
Safety and Other Assessments
10.3.1 The safety of the study medication 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 (PCS)

Clinically meaningful changes in physical examination findings including vital signs
10.3.2 Quality of Life Assessment EORTC QLQ – NMIBC24 
The QLQ- NMIBC24 is a 24-item validated, evidence-driven survey that assesses Health Related 
Quality of Life (HRQOL) for patients with intermediate to high risk NMIBC (Appendix 1). It is 
designed to be administered at baseline and at, 3, 6 and 12-month intervals. The NMIBC24 is the 
only instrument exclusively designed to compare HRQOL between non-muscle-invasive 
treatment modalities. 
10.4
Adverse Events and Serious Adverse Events
10.4.1 Definition of Adverse Events
An AE means any untoward medical occurrence associated with the use of an intervention in 
humans, whether or not considered intervention-related (21 Code of Federal Regulations [CFR] 
312.32 [a]). An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory, physical examination, or vital signs finding), 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). 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. AEs 
must be recorded in the eCRF using CTCAE to avoid the use of vague, ambiguous, or colloquial 
expressions. The investigator shall evaluate all AEs in terms of severity and their relationship 
with the product being tested, indicating the test results and the measures to be taken.
10.4.2 Definition of Serious Adverse Events 
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: death, a life-threatening AE, 
inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant 
incapacity or substantial disruption of the ability to conduct normal life functions, or a congenital 
anomaly/birth defect. Important medical events that may not result in death, be life-threatening, 
or require hospitalization may be considered serious when, based upon appropriate medical 
judgment, they may jeopardize the patient and may require medical or surgical intervention to 
prevent one of the outcomes listed in this definition. Examples of such medical events include

allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in inpatient hospitalization, or the development of 
drug dependency or drug abuse.
10.4.3 Classification of an Adverse Event
10.4.3.1 Intensity of Event
The intensity of an AE is to be graded by the investigator according to CTCAE version 4.03. 
General rules are as follows:
0
No AE (or within normal limits)
1
Mild: asymptomatic or mild symptoms; clinical or diagnostic observations only, 
intervention not indicated
2
Moderate: minimal, local, or noninvasive intervention (e.g., 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)
10.4.3.2 Relationship to Study Medication
All AEs must have their relationship to study medication assessed by the clinician who examined 
and evaluated the patient based on temporal relationship and his/her clinical judgment. In a 
clinical trial, the study product must always be suspect. Investigators will be asked to grade each 
AE as either related or unrelated.
10.4.3.3 Expectedness
The investigator will be responsible for determining whether an AE is expected or unexpected. 
An AE will be considered unexpected if the nature, intensity, or frequency of the event is not 
consistent with the risk information previously described for the study medication.
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 this protocol or the 
Investigator’s Brochure, 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.
10.4.4 Time Period and Frequency for Event Assessment and Follow-Up
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.
All AEs, including local and systemic reactions not meeting the criteria for SAEs, will be 
captured on the appropriate eCRF. Information to be collected includes event description, time of 
onset, clinician’s assessment of intensity, relationship to study product (assessed only by those

with the training and authority to make a diagnosis), and time of resolution/stabilization of the 
event. All AEs occurring while on study must be documented appropriately regardless of 
relationship. All AEs will be followed to adequate resolution/stabilization.
Any medical condition that is present at the time that the patient signs the informed consent form 
(ICF) until the first study drug administration will be considered as baseline and recorded as 
medical history. However, 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 drug administration until 
30 days after the last dose of study medication will be considered as treatment emergent adverse 
events (TEAEs).
Changes in the intensity of an AE will be documented to allow an assessment of the duration of 
the event at each level of intensity to be performed. AEs characterized as intermittent require 
documentation of onset and duration of each episode.
At each study visit, the investigator will inquire about the occurrence of AE/SAEs since the last 
visit. The investigator or designated investigational staff member will record the start date of all 
reportable events. Events will be followed for outcome information until resolution or 
stabilization and the dates of outcome must be recorded.
10.4.5 Adverse Event Reporting 
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 about the above by writing using the relevant form 
signed by the investigator, to be sent by email/fax within 24 hours after its occurrence first came 
to his/her knowledge.
10.4.6 Serious Adverse Event Reporting
The investigator will immediately report to the sponsor any SAE, whether or not considered 
study medication-related, including those listed in the protocol or Investigators Brochure and 
must include an assessment of whether there is a reasonable possibility that the study medication 
caused the event. Study endpoints that are SAEs (e.g., all-cause mortality) must be reported in 
accordance with the protocol, unless there is evidence suggesting a causal relationship between 
the study medication and the event (e.g., death from anaphylaxis). In that case, the investigator 
must immediately report the event to the Sponsor.
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 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 IND safety report of potential 
serious risks, from clinical trials 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.
10.4.6.1 SAE Reporting Instructions
The investigator must inform the sponsor within 24 hours of becoming
aware of an SAE with an email to:
safety@urogen.com with copies to sponsor@urogen.com
In addition, initial SAE/Death/Pregnancy must be recorded in the electronic Case Report Form 
(eCRF) within 24 hours of becoming aware of the event. 
10.4.7 Reporting Events to Patients 
Not applicable.
10.4.8 Adverse Events of Special Interest 
Adverse events of special interest are defined by the FDA (E2F Development Update Safety 
Report) as an AE, serious or nonserious, which is of scientific and medical concern specific to the 
Sponsor’s product or program, for which ongoing monitoring and rapid communication by the 
investigator to the sponsor can be appropriate. Such an event might warrant further investigation 
in order to characterize and understand it.
Events of Special Interest that may require expedited reporting and/or safety evaluation include, 
but are not limited to, the following:
1. Overdose of an IP
2. Suspected abuse/misuse of IP
3. Inadvertent or accidental exposure to IP
4. Medication error involving IP (with or without patient/patient exposure to the Sponsor 
medicinal product, e.g., name confusion)
5. Identified significant safety issue either from an individual case report or review of 
aggregate data
In addition, 
lists specific AEs defined as AESIs with suggested actions to be taken to address them.

Other Safety Assessments
10.5.1 Laboratory Assessments
Samples for hematology and serum chemistry assessments will be taken according to the SoA in 
Section 1.3 and tested at the local laboratory. The amount of blood required for hematology and 
serum chemistry tests per visit is 15 to 20 mL. The assessments to be performed are listed in 
Table 4. Additional tests may be part of a clinical site’s local lab’s standard panel and therefore 
reported along with these specified tests.
10.5.1.1 Other significant laboratory derangements
If at any time the investigator identifies myelosuppression or other significant laboratory 
derangements during the study defined by the parameters below, treatment may be
postponed for up to 4 weeks until laboratory values improve:

Absolute neutrophil count ≥1,000/μL (≥1.0×109/L),

Platelets ≥80,000/μL (≥80×109/L)

AST (SGOT)/ALT (SGPT) ≥5 × upper limit of normal (ULN)

ALP ≥2.5 institutional ULN

For patients whose baseline GFR is ~30 mL/min/1.73m2, decreases of up to 15% will be 
allowed

For patients with normal baseline creatinine, increases of up to 2x will be allowed

10.5.2 Pharmacokinetic (PK) Assessments
At select sites, six (6) patients will be asked to participate and consent to provide blood samples 
for PK analysis. On the day of first instillation, this subset of patients will provide blood samples 
at 0 hours (pre-instillation), 0.5, 1, 2, 3, 4, 5, and 6 hours post instillation. Sites will be 
encouraged to use a catheter to lessen the number of needle sticks to the patient. Patients will be 
required to remain in the clinic for approximately 6 hours post instillation or agree to return for 
each blood draw at the appropriate time. The total amount of blood drawn for PK will be 
approximately 40 mL.

11 STATISTICAL CONSIDERATIONS 
11.1
Statistical Hypotheses
Analyses are descriptive and exploratory in nature and no formal hypotheses will be tested.
11.2
Sample Size Determination
Approximately 66 patients will enter the study, with 60 expected to complete, assuming 10% 
dropout rate. Given the patient population under study, i.e., those at intermediate risk of 
recurrence, a more conservative CR rate than previous studies of UGN-102 in the treatment of 
LG NMIBC has been assumed. The primary objective will be successfully achieved if complete 
responses from 36 out of 60 patients with CR rate of 60% will be observe, which would yield a 
95% confidence interval of (46.5%, 72.4%) based on the exact (Clopper-Pearson) binomial 
distribution.

11.3
Populations for Analyses
11.3.1 Intent-to-Treat (ITT) Analysis Set (Safety Analysis Set)
The Intent-to-Treat (ITT) Analysis set will consist of all patients who have been enrolled into the 
trial and who have received any instillation of UGN-102 preparation. This analysis set, which 
will include all data captured in the database for these patients, will serve as the primary set for 
the primary efficacy endpoint analysis and will serve as the analysis set for the secondary safety 
endpoint analyses.
11.3.2 Modified Intent-to-Treat (mITT) Analysis Set
The Modified Intent-to-Treat (mITT) Analysis Set will consist of all patients who have been 
enrolled into the trial, who have a confirmed diagnosis of LG NMIBC based on the local 
pathology reading, who received at least 1 instillation of UGN-102 preparation, and who have 
undergone the 3 MONTH Visit (since it is the first visit for the outcome evaluation). 
11.3.3 Per Protocol (PP) Analysis Set
The Per Protocol (PP) Analysis Set will consist of all patients who have been enrolled into the 
trial, who have a confirmed diagnosis of LG NMIBC based on the local pathology reading, who 
received all 6 weekly instillations of UGN-102 preparation, and who have undergone the 
3 MONTH Visit. Patients who are identified as HG by local pathology reading at the 3 MONTH 
visit will be excluded from this analysis set. This analysis set, which will include all data 
captured in the database for these patients, will serve as supportive data for the primary efficacy 
endpoint analysis.
11.3.4 Complete Response at Primary Outcome Analysis Set
The Complete Response at 3 MONTH Visit (3 MONTHCR) Analysis Set will consist of all 
patients who achieved CR at the 3 MONTH Visit (Study Visit 7). This analysis set, which will 
include all data captured in the database for these patients, will serve as the primary set for the 
secondary efficacy endpoint analysis.
11.4
Statistical Analyses
A formal Statistical Analysis Plan (SAP) will be developed and finalized prior to database lock. 
The SAP will supersede this statistical analysis section.
11.4.1 General Approach
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% confidence interval (CI) for 
proportions using the exact approach. For continuous variables, summary tables will be provided 
giving sample size, arithmetic mean, standard deviation (SD), coefficient of variation (if 
appropriate), median, minimum and maximum, percentiles, and 95% CI for means of variables. 
For variables with non-normal distribution, medians and interquartile range (IQR) will be 
calculated, and the appropriate non-parametric tests will be applied.

11.4.2 Analysis of the Primary Efficacy Endpoint
The analysis of the primary endpoint will test the CR rate defined as percentage of patients with 
CR at the 3 MONTH Visit using the ITT Analysis Set.
A test for binomial proportions (SAS PROC FREQ with binomial option) will be used to derive 
the exact 95% CI for the true CR rate.
11.4.3 Sensitivity Analysis of the Primary Efficacy Endpoint
Sensitivity analysis of the primary endpoint will include repeat of the primary efficacy analysis 
(Section 11.4.2) using the PP Analysis Set, i.e., including only patients who received all 
6 instillations of UGN-102 preparation and are LG at baseline (patients with HG at 3 MONTH 
Visit will be excluded).
11.4.4 Analysis of the Secondary Efficacy Endpoints
One key secondary endpoint is pre-defined for this trial: the durable complete response (DCR) 
rate at 6, 9, and 12 months after the first instillation of UGN-102 preparation, defined as the 
percentage of patients who continue to display CR at Study Visits 10, 13, and 16, respectively.
Analysis will use the 3 MONTHCR Analysis Set, implying that the denominator for this analysis 
will be the number of patients who demonstrated CR at the 3 MONTH Visit. Patients who 
withdraw early from the trial between the 3-MONTH Visit and Study Visit 16 for whom 
follow-up data regarding the disease status (i.e., recurrence) is not available will be treated as 
follows:

Patients who discontinue during this time window due to adverse reactions from the study 
medication, lack of efficacy, death, or any other cancer-related reason will be considered 
as treatment failures for the purpose of this analysis.

Patients who withdraw during this time window due to reasons other than those given 
above will be excluded from the analysis.
A test for binomial proportions (SAS PROC FREQ with binomial option) will be used to derive 
the exact 95% CI for the true DCR rate at 6, 9, and 12 months.
11.4.5 Safety Analyses
11.4.5.1 Adverse Events and Serious Adverse Events
Adverse events will be recorded from the time a patient has signed the informed consent until 
30 days after the last instillation of study medication. AEs reported by the investigators will be 
coded according to the Medical Dictionary for Regulatory Activities (MedDRA).
The following will be incorporated into the analysis of AEs:

All analyses to be provided will include coded AEs.

AE analyses will include both all AEs and treatment-emergent AEs (TEAEs), i.e., events 
that started on the day of first administration of study medication or afterwards, or that 
were present before first administration of study medication and increased in intensity

after first administration of study medication. Listings of both TEAEs and non-TEAEs 
will be provided.

The incidence (number of patients) and frequency (number of events) of TEAEs will be 
provided, broken down by System Organ Class (SOC) and by Preferred Term (PT) 
according to MedDRA.

The incidence (number of patients) and frequency (number of events) of TEAEs will be 
provided, broken down by descending frequency by PT according to MedDRA.

Breakdowns of TEAEs by all AE attributes will also be provided.

Breakdowns of TEAEs by age and sex will also be provided.

The derived dictionary used in the analyses displaying the MedDRA SOC and PT and the 
AE verbatim term as specified by the investigator, will be provided.

The incidence and frequency of treatment-emergent SAEs will be provided, broken down 
by SOC and by PT according to MedDRA, as well as by SAE attributes and by age and 
sex. Listings of both treatment-emergent and non-treatment-emergent SAEs will be 
provided.
11.4.5.2 Laboratory Assessments
Analyses of safety laboratory data will be performed for all collected laboratory parameters. 
Quantitative laboratory measurements will be categorized with reference to the normal ranges as 
Low, Normal, or High. Shift analysis of the categorical change from baseline to each scheduled 
visit and to the last observed assessment will also be performed.
A list of parameters and related cut-off values defining the PCS abnormal values will be outlined 
by the Sponsor prior to initiation of the first trial instillation. Measurements used in the analysis 
are those taken following first trial instillation. The incidence tables of PCS laboratory values as 
well as the individual patient listing will be provided using the denominator that is the number of 
patients with at least 1 post-baseline administration of trial medication. Individual patients’ 
listings of PCS measurements will also be presented.
11.4.5.3 Physical Examination
Any clinically relevant changes occurring from Screening until the last trial visit will be recorded 
on the Adverse Event Sections of the eCRF and reported with AEs as described above.
11.4.5.4 Vital Signs
Analyses of vital signs (blood pressure, heart rate, respiration rate, and body temperature) will be 
performed using descriptive statistics of vital signs before Screening, instillation, and during the 
trial, and by presenting changes from baseline by scheduled visit.
11.4.5.5 Concomitant Medications
The WHO drug dictionary will be used to classify medications verbatim for concomitant and pre-
trial medications. Analysis of concomitant drug use will be performed in the following manner:


Pre-instillation concomitant medications use: Analyses will include coded medications 
that were initiated prior to first instillation, regardless if stopped after the first instillation. 
An incidence table including patient counts (number of patients) and percentages broken 
down by Medication Class and PT will be provided.

Concomitant medications use (post-first instillation): Analyses will include only coded 
medications that were administered following the first instillation, regardless if drug 
initiation date was before or after first instillation. An incidence table including patient 
counts (number of patients) and percentages broken down by Medication Class and PT 
will be generated.
11.4.5.6 MMC Levels (Pharmacokinetics) Profiling
Pharmacokinetic (PK) profile during the 6 hours following the first administration of UGN-102 
will be based on PK sampling at 0 (pre-instillation), 0.5, 1, 2, 3, 4, 5, and 6 hours post instillation. 
PK will be performed with just 6 patients who provide informed consent for PK testing. 
Concentration data as well as PK parameters (e.g., AUC) will be provided using descriptive 
statistics. Plasma samples for evaluation of PK properties of MMC following instillation with 
UGN-102 Admixture will be collected and archived. These samples are to be used to characterize 
the plasma concentration of MMC during the 6 hours post instillation, which is the estimated 
duration of the dwell-time of UGN-102 Admixture. The PK parameters obtained, specifically the 
Cmax, will be compared to the threshold of MMC plasma concentration (400 ng/mL) known to be 
associated with myelosuppression, as well as to the known PK profile of MMC obtained with 
different routes/methods of administration (e.g., intravesical instillation with WFI).
Additionally, these data, combined with data emerging from other trials may be used in 
population pharmacokinetic model development and analysis. 
11.4.6 Baseline Descriptive Statistics
Disposition data from patients who were screened but not treated, patients in the ITT, mITT, PP, 
and 3 MONTHCR Analysis Sets, as well as trial withdrawal data will be summarized using 
descriptive statistics.
Demographics and baseline data, as well as disease prognostic factors, medical history, and prior 
medications, will be summarized for the ITT Analysis Set using descriptive statistics. For 
continuous variables, descriptive statistics (number, mean, SD, standard error, median, minimum, 
and maximum) will be provided. For categorical variables, patient counts and percentages will be 
provided. Categories for missing data will be presented if necessary. Missing categories will be 
presented if necessary.
11.4.7 Planned Interim Analyses 
When approximately 12 patients have reached their Month 3 visit an interim analysis will be 
performed for primary endpoint.

12 SUPPORTING DOCUMENTATION AND OPERATIONAL 
CONSIDERATIONS
12.1
Regulatory, Ethical, and Study Oversight Considerations
12.1.1 Informed Consent Process
12.1.1.1 Consent/Assent and Other Informational Documents Provided to Patients
Consent forms describing in detail the study medication, study procedures, and risks are given to 
the patient, and written documentation of informed consent is required prior to initiating any 
study procedures and starting medication/administering study medication. The informed consent 
form (ICF) template is submitted with this protocol. 
12.1.1.2 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/designee will explain the research study to the patient and answer any questions that 
may arise. 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. The patient will sign 
the informed consent document prior to any procedures being done specifically for the study. 
Patients must be informed that participation is voluntary and that they may withdraw from the 
study at any time, without prejudice. A copy of the informed consent document will be given to 
the patients for their records. 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.
12.1.2 Study Discontinuation and Closure
This study may be temporarily suspended or prematurely terminated if there is sufficient 
reasonable cause. Written notification, documenting the reason for study suspension or 
termination, will be provided by the suspending or terminating party to study patients, 
investigator, Sponsor, and regulatory authorities. If the study is prematurely terminated or 
suspended, the investigator will promptly inform study patients, the IRB, and the Sponsor and 
will provide the reason(s) for the termination or suspension. Study patients will be contacted, as 
applicable, and be informed of changes to the study visit schedule.

Circumstances that may warrant termination or suspension include, but are not limited to, the 
following:

Determination of unexpected, significant, or unacceptable risk to patients

Demonstration of efficacy that would warrant stopping

Insufficient compliance to protocol requirements

Data that are not sufficiently complete and/or evaluable

Determination that the primary endpoint has been met
The study may resume once concerns about safety, protocol compliance, and data quality are 
addressed, and satisfy the sponsor, IRB, and/or FDA.
12.1.3 Confidentiality and Privacy 
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 monitor, other authorized representatives of the Sponsor, representatives of the IRB, 
regulatory agencies, or pharmaceutical company supplying the study product may inspect all 
documents and records required to be maintained by the investigator, including, but not limited 
to, medical records (office, clinic, or hospital) and pharmacy records for the patients in this study. 
The clinical study site will permit access to such records.
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.
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.
12.1.4 Future Use of Stored Specimens and 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.

12.1.5 Safety Oversight
Safety oversight will be under the direction of the Sponsor. Safety oversight will be independent 
from the study conduct and free from conflict of interest. 
12.1.6 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 a trial 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.
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 trial-related documents. The monitor will meet with the investigator on a regular basis during 
the trial to provide feedback on the trial conduct. Further details of clinical 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.
12.1.7 Quality Assurance and Quality Control
Each clinical site will perform internal quality management of study conduct, data and biological 
specimen collection, documentation, and completion. An individualized quality management plan 
will be developed to describe a site’s quality management.
Quality control (QC) procedures will be implemented beginning with the data entry system and 
data QC checks that will be run on the database. Any missing data or data anomalies will be 
communicated to the sites for clarification/resolution.
Following written Standard Operating Procedures (SOPs), the monitors will verify that the 
clinical trial is conducted, data are generated, and biological specimens are collected, documented 
(recorded), and reported in compliance with the protocol, ICH GCP, and applicable regulatory 
requirements (e.g., Good Laboratory Practices [GLP], GMP). 
The investigational site will provide direct access to all trial-related sites, source data/documents, 
and reports for the purpose of monitoring and auditing by the Sponsor and inspection by local 
and regulatory authorities.

12.1.8 Data Handling and Record Keeping 
12.1.8.1 Data Collection and Management Responsibilities 
This study will use an Electronic Data Capture (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 electronic data capture 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 trial staff at the site under the supervision of 
the site investigator. 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 no later than 5 days from each visit. 
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.
Clinical data (including AEs, concomitant medications, and expected adverse reactions data) and 
clinical laboratory data will be entered in the eCRF using a 21 CFR Part 11-compliant electronic 
data capture system. The data system includes password protection and internal quality checks, 
such as automatic range checks, to identify data that appear inconsistent, incomplete, or 
inaccurate. Clinical data will be entered directly from the source documents.
12.1.8.2 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 medication. These documents should be 
retained for a longer period, however, if required by local regulations. No records will be 
destroyed 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.
12.1.9 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.
