Brief Title: CG0070 Given in Combination With Pembrolizumab, in Non-Muscle Invasive Bladder Cancer, Unresponsive to Bacillus Calmette-Guerin

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)


  • Org Study ID: CG2003C
  • Secondary ID: N/A
  • NCT ID: NCT04387461
  • Sponsor: CG Oncology, Inc.


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.


An opened label trial designed to evaluate CG0070 and DDM in combination with Pembrolizumab in patients with NMIBC who have failed prior BCG therapy.

The target population of 37 subjects with CIS with or without concomitant high-grade Ta or T1 papillary disease will be enrolled.

BCG failure is defined as persistent or recurrent disease within 12 months of completion of adequate BCG therapy.

Key Inclusion Criteria:
* Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1

- * Pathologically confirmed NMIBC with CIS (with or without Ta/T1 disease)

An assessment within 15 months can also qualify when no assessment was performed within 12 months after completion of adequate BCG therapy.
* Adequate BCG is defined as at least 5 treatments with induction BCG followed by at least 2 BCG treatments as reinduction or maintenance

- * Ineligible for radical cystectomy or refusal of radical cystectomy

- * Adequate organ function
Key Exclusion Criteria:
