Protocol Summary

Protocol No.: OCR15795

Sponsor Protocol No.: rAd-IFN-CS-003; Instiladrin

Study Title
A Phase III, Open Label Study to Evaluate the Safety and Efficacy of INSTILADRIN® (rAd-Interferon (IFN)/Syn3) Administered Intravesically to Patients With High Grade, BCG Unresponsive Non-Muscle Invasive Bladder Cancer (NMIBC)

Principal Investigator(s)
Crispen, Paul

Previous multi-dose Phase I and Phase II clinical studies have demonstrated that Instiladrin nadofaragene firadenovec 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 Instiladrin 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.

Recombinant IFN alpha2b has pleiotropic effects that contribute to antitumor activity in Non-Muscle Invasive Bladder Cancer (NMIBC). Instiladrin nadofaragene firadenovec 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 amount of IFN alpha2b protein. Clinical studies have confirmed that IFN alpha2b protein can be measured in patients treated with Instiladrin within 24 hours after dosing.

Phase: Phase III

Age Group: Adult

Scope: National

Intravesical administration of INSTILADRIN nadofaragene firadenovec into the bladder

Detailed Eligibility
1. Ages 18 years old and older
2. Able to give informed consent
3. 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
4. Are "BCG Unresponsive" which refers to patients with high grade NMIBC who are unlikely to benefit from and who will not receive 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 NMIBC within 12 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.
5. Available for the whole duration of the study
6. Life expectancy >2 years, in the opinion of the investigator
7. Eastern Cooperative Oncology Group (ECOG) status 2 or less
8. 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
9. Patients with prostate cancer on active surveillance at low risk for progression, defined as Prostate-Specific Antigen (PSA) 10. Female patients of childbearing potential must use maximally effective birth control during the period of therapy, must be willing to use contraception for 1 month following the last study drug infusion and must have a negative urine or serum pregnancy test upon entry into this study. 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
11. Male patients must be surgically sterile or willing to use a double barrier contraception method upon enrollment, during the course of the study, and for 1 month following the last study drug infusion
12. Adequate lab values
