Study Title

A Phase 2, Single Arm Study of CG0070 Combined with Pembrolizumab in Patients with Non Muscle Invasive Bladder Cancer (NMIBC) Unresponsive to Bacillus Calmette-Guerin (BCG)


To evaluate the activity of intravesical administration of CG0070 and intravenous administration of Pembrolizumab in patients with tissue pathology-confirmed non-muscular invasive bladder cancer (NMIBC) who have Bacillus-Calmette-Guerin (BCG) unresponsive disease with carcinoma in situ (CIS) with or without Ta/T1 papillary disease.


Primary: Evaluate the complete response rate at 12 months of CG0070 combined with pembrolizumab in patients with BCG unresponsive CIS with or without concomitant high-grade Ta or T1 papillary disease




CG0070 (); DDM (); Pembrolizumab (Keytruda)
