Summary

This trial will test the effectiveness of CG0070, given through the bladder, in patients with NMIBC that has not responded to BCG treatment.

Who is the study for?
This trial is for adults with high-risk non-muscle invasive bladder cancer that hasn't responded to BCG therapy. Participants should be in fair to good physical condition (ECOG 0-2), not eligible or unwilling to undergo radical cystectomy, and have proper organ function. Those with muscle-invasive, advanced, or metastatic bladder cancer, other malignancies in the urinary tract, recent systemic anti-cancer treatments, immune deficiencies including HIV or past organ transplants are excluded.
What is being tested?
The study tests CG0070 given directly into the bladder of patients who haven't responded to BCG treatment for their bladder cancer. It aims to see how effective this approach is. The intervention involves a compound called n-dodecyl-B-D-maltoside alongside CG0070 as part of the treatment process.
What are the potential side effects?
Potential side effects may include irritation within the bladder where CG0070 is administered, typical reactions related to intravesical therapies such as discomfort during urination, increased frequency of urination and blood in urine. Systemic side effects could occur but are less common.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Cohort P(Japan and United States Only) :Open to EnrollmentExperimental Treatment2 Interventions
HG Ta/T1 papillary disease bladder cancer patients. In Cohort P, cretostimogene will be administered at a dose of 1 × 1012vp IVE following instillation of 5% DDM. Cretostimogene will be administered every week for 6 treatments on Weeks 1, 2, 3, 4, 5, and 6. If the patient has recurrence at Week 13 or any timepoint, the patient will receive a second induction of 6 weekly treatments (Weeks 13, 14, 15, 16, 17, and 18.). If the tumor has not returned they will receive 3 weekly treatments every 12 weeks (approximately 3 months) starting Weeks 13, 14, and 15 through Week 51 (approximately 12 months), and then every 6 months starting at Weeks 73, 74, and 75 (approximately 18 months) through Month 36.
Group II: Cohort C(All Countries):Enrollment ClosedExperimental Treatment2 Interventions
Patients with CIS with or without HG Ta/T1 papillary disease. Cretostimogene will be administered intravesically following a series of bladder washes with 5% DDM and normal saline. Cretostimogene will be administered weekly x 6 on Weeks 1, 2, 3, 4, 5, and 6. If the patient has disease recurrence at Week 13, they will receive another cycle of 6 weekly treatments. If there is no disease present at Week 13 then the patient will receive 3 weekly treatments. Cohort C(All Countries):Beginning at Week 25, patients will receive weekly x 3 treatments every 12 weeks through week 51 then every 6 months and then a last treatment at Weeks 73, 74, and 75 until the tumor returns or study treatment is completed at Week 97. Cohort C Extension( Japan and the US) At Week 25, patients will receive weekly x 3 treatments every 12 weeks through week 51 then every 6 months starting at Weeks 73, 74, and 75 through Weeks 157, 158, and 159 until the tumor returns or study treatment is completed at Week 159.
