Brief Summary:
Previous multi-dose Phase I and Phase II clinical studies have demonstrated that ADSTILADRIN is a safe and effective treatment for BCG-refractory and recurrent NMIBC. This Phase III study is designed to expand those observations using a high dose of ADSTILADRIN in patients that are "BCG Unresponsive" which refers to patients with high-grade NMIBC who are unlikely to benefit from and should not receive further intravesical BCG.

| Superficial Bladder Cancer | Biological: ADSTILADRIN | Phase 3 |
Recombinant IFN alpha2b has pleiotropic effects that contribute to antitumor activity in Non-Muscle Invasive Bladder Cancer (NMIBC). ADSTILADRIN is a non-replicating adenovirus vector harboring the human IFN alpha2b gene. When combined with the excipient Syn3, intravesical administration of the rAd-IFN results in transduction of the virus into the epithelial cell lining in the bladder. The IFN alpha2b gene is incorporated into the cellular DNA resulting in the synthesis and expression of large amounts of IFN alpha2b protein. Clinical studies have confirmed that IFN alpha2b protein can be measured in the urine of patients treated with ADSTILADRIN within 24 hours after dosing.

Primary Outcome Measures :
- Number of Patients With a Complete Response Rate in Patients With Carcinoma in Situ (CIS), With or Without Concomitant High-grade Ta or T1 Papillary Disease. [ Time Frame: 12 Months ]A patient in the CIS cohort was judged to have achieved CR where urine cytology was reported as normal, atypical, degenerative, reactive, inflammatory, or nonspecific AND cystoscopy was reported as normal or with findings that did not include evidence of low-grade or high-grade recurrence. Bladder biopsy, if performed (not mandatory), demonstrated an absence of low-grade or high-grade recurrence.
Secondary Outcome Measures :
- Durability of Complete Response in Patients With CIS (With or Without Concomitant Ta or T1 Papillary Disease) Who Achieve a Complete Response. [ Time Frame: Up to 60 months ]Durability will be measured by determining the number of patients without recurrence of high-grade disease using results from urine cytology, cystoscopy, and biopsy of the bladder.
- Rate of Event-free Survival, Where Event-free Survival is Defined as High-grade Recurrence Free Survival in Patients With High-grade Ta or T1 Disease (Without Concomitant CIS) [ Time Frame: up to 60 months ]Complete response rate will be measured by determining the number of patients without recurrence of high-grade disease using results from urine cytology, cystoscopy, and biopsy of the bladder.
- Durability of Event-free Survival in Patients With High-grade Ta or T1 Papillary Disease (Without Concomitant CIS), Who Have no Recurrence of High-grade Ta or T1 Papillary Disease. [ Time Frame: Up to 60 months ]Durability will be measured by determining the number of patients without recurrence of high-grade disease using results from urine cytology, cystoscopy, and biopsy of the bladder if clinically indicated.
- Incidence of Cystectomy in the Study [ Time Frame: 60 Months ]The incidence of and time to cystectomy will be measured in the study
- Overall Survival in All Patients [ Time Frame: 60 Months ]The incidence of and time to survival will be measured in the study
- Anti-adenoviral Antibody Levels for Correlation to Response Rate [ Time Frame: 12 Months ]
Measurement of anti-adenoviral antibody levels at each dosing period, withdrawal, and at 12 months were done. A patient was considered to have a positive immunogenic response in anti-adenoviral antibodies if a post-baseline titration demonstrated a greater than 2-fold increase from baseline.
The table represent data at any time during the 12 months period, which means that the patient will be included in the Yes group if they at any measurement during the trial has a 2-fold increase from baseline.
- Safety of ADSTILADRIN [ Time Frame: 60 Months ]The type, incidence, relatedness and severity of treatment emergent adverse events of ADSTILADRIN as assessed by NCI-CTCAE V4.03 will be monitored.
- Durability of Response During the Long Term Follow up Period. [ Time Frame: 60 Months ]Durability will be measured by determining the number of patients without recurrence of high-grade disease using results from urine cytology, cystoscopy, and biopsy of the bladder if clinically indicated.

| Accepts Healthy Volunteers: | No |
Criteria
Inclusion Criteria:
- Aged 18 years or older at the time of consent
- Able to give informed consent
-
Have, at entry, confirmed by a pathology report:
Carcinoma in situ (CIS) only; Ta/T1 high-grade disease with concomitant CIS; or Ta/T1 high-grade disease without concomitant CIS
-
Are "BCG Unresponsive" which refers to patients with high-grade NMIBC who are unlikely to benefit from and who will not receiving further intravesical BCG. The term "BCG unresponsive" includes patients who did not respond to BCG treatment and have a persistent high-grade recurrence within 12 months after BCG was initiated, and those who despite an initial complete response (CR) to BCG, relapse with high-grade CIS within 12 months of their last intravesical treatment with BCG or relapse with high-grade Ta/T1 NMIBC within 6 months of their last intravesical treatment with BCG. The following criteria define the patients who may be included in the study:
-
Have received at least 2 previous courses of BCG within a 12 month period - defined as at least 5 of 6 induction BCG instillations and at least 2 out of 3 instillations of maintenance BCG, or at least two of six instillations of a second induction course, where maintenance BCG is not given
- Exception: those who have T1 high-grade disease at first evaluation after induction BCG alone (at least 5 of 6 doses) may qualify in the absence of disease progression
- At the time of tumor recurrence, patients with CIS alone or high-grade Ta/T1 with CIS should be within 12 months of last exposure to BCG and patients with Ta/T1 without CIS should be within 6 months of last exposure to BCG
- No maximum limit to the amount of BCG administered
- All visible papillary tumors must be resected and those with persistent T1 disease on transurethral resection of bladder tumor (TURBT) should undergo an additional re-TURBT within 14 to 60 days prior to beginning study treatment. Obvious areas of CIS should also be fulgurated.
-
- Available for the whole duration of the study
- Life expectancy >2 years, in the opinion of the investigator
- Eastern Cooperative Oncology Group (ECOG) status 2 or less
- Absence of concomitant upper tract urothelial carcinoma or urothelial carcinoma within the prostatic urethra. Freedom from upper tract disease (if clinically indicated) as indicated by no evidence of upper tract tumor by either intravenous pyelogram, retrograde pyelogram, computed tomography (CT) scan with or without urogram, or MRI with or without urogram performed within 6 months of enrollment
- Patients with prostate cancer on active surveillance at low risk for progression, defined as Prostate-Specific Antigen (PSA) < 10 ng/dL, Gleason score 6 and clinical stage tumor-1 (cT1) are permitted to be in the study at the discretion of the investigator (see exclusion criterion 10).

Otherwise, female patients must be postmenopausal (no menstrual period for a minimum of 12 months) or surgically sterile. 'Maximally effective birth control' means that the patient, if sexually active, should be using a combination of two methods of birth control that are approved and recognized to be effective by Regulatory Agencies
