|Condition or disease||Intervention/treatment||Phase|
|Non Muscular Invasive Bladder Cancer||Biological: CG0070 Other: n-dodecyl-B-D-maltoside||Phase 3|
An open-label trial designed to evaluate CG0070 + DDM in patients with NMIBC who have failed prior BCG therapy. Single treatment arm that will enroll up to 110 patients with carcinoma in situ with or without concomitant high-grade Ta or T1 papillary disease
BCG failure is defined as a persistent or recurrent disease within 12 months of completion of adequate BCG therapy.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||110 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Phase 3 Study of CG0070 in Patients With Non-Muscle Invasive Bladder Cancer (NMIBC) Unresponsive to Bacillus-Calmette-Guerin (BCG)|
|Actual Study Start Date :||October 27, 2020|
|Estimated Primary Completion Date :||January 31, 2024|
|Estimated Study Completion Date :||July 31, 2025|
Experimental: Single Arm
Patients with carcinoma in situ with or without concomitant high-grade Ta or T1 papillary disease.
CG0070 will be administered intravesically (IVE) following a sequence of bladder washes with 5% DDM and normal saline. CG0070 will be administered weekly x 6 on Weeks 1, 2, 3, 4, 5, and 6. If the patient has persistent high-grade disease at Week 13, the patient will receive another cycle of 6 weekly treatments. If there is no disease present at Week 13 (e.g. complete response) then the patient will receive 3 weekly treatments.
Beginning at Week 25, patients will receive weekly x 3 treatments every 12 weeks through week 49then every 24 weeks thereafter.

- Complete response rate in patients with carcinoma in situ (with or without concomitant high-grade Ta or T1 papillary disease) [ Time Frame: 24 months ]Percentage of patients with a complete response as defined by FDA guidance document dated February 2018 for NMIBC.
- Median Duration of response (DOR) [ Time Frame: 24 months ]Median duration of response in patients with a CR or PR in subjects
- Median progression free survival [ Time Frame: 24 months ]Median duration of progression free survival of subjects
- Time to tumor progression (TTP) [ Time Frame: 24 months ]Median time until patient disease progression (PD) in subjects
- Incidence of adverse events when CG0070 administered alone. [ Time Frame: 24 months ]Percentage of patients with adverse events by grade as determined by NCI CTCAE v5.0.
- Comparison of complete response in patients with persistent disease versus relapsed disease at baseline. [ Time Frame: 24 months ]Percentage in CR
