| Arm | Type | Description |
|---|---|---|
| Cretostimogene after TURBT | EXPERIMENTAL | Following screening confirmation of IR-NMIBC and complete resection of the tumor, participants will be treated with adjuvant cretostimogene. |
| Observation after TURBT | NO_INTERVENTION | Following screening confirmation of IR-NMIBC and complete resection of tumor, participants will enter surveillance. Participants who recur with IR-NMIBC after TURBT and surveillance will be offered treatment with cretostimogene as per the treatment schedule in Arm A. This arm will be called the Extension Arm. |
| Cohort C(All Countries):Enrollment Closed | EXPERIMENTAL | 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. |
| Cohort P(Japan and United States Only) :Open to Enrollment | EXPERIMENTAL | 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. |
| Experimental: Cohort A, Arm 1 | EXPERIMENTAL | Cretostimogene (1 x 1012 vp) will be administered intravesically via the current instillation method |
| Experimental: Cohort A, Arm 2 | EXPERIMENTAL | Cretostimogene (1 x 1012 vp) will be administered intravesically via an alternative instillation method. |
| Experimental: Cohort A, Arm 3 | EXPERIMENTAL | Cretostimogene (1 x 1012 vp) will be administered intravesically via an alternative instillation method. |
| Experimental: Cohort B, Arm 1 | EXPERIMENTAL | Cretostimogene (1 x 1012 vp) will be administered intravesically via an alternative instillation method. |
| Experimental: Cohort B, Arm 2 | EXPERIMENTAL | Cretostimogene (1 x 1012 vp) will be administered intravesically via an alternative instillation method. |
| Experimental: Cohort CX, Arm 1 | EXPERIMENTAL | At all treatment visits cretostimogene (1 x 1012 vp) will be administered intravesically via an alternative instillation method followed by gemcitabine instilled intravesically |
| Experimental: Cohort CX, Arm 2 | EXPERIMENTAL | Cretostimogene (1 x 1012 vp) will be administered intravesically via an alternative instillation method for two consecutive weeks, followed by gemcitabine administered intravesically in the third week on a cyclic 2:1 visit schedule basis |

Cretostimogene Grenadenorenepvec is an investigational gene therapy being developed for the treatment of non-muscle-invasive bladder cancer (NMIBC), including high-risk NMIBC. It is currently in clinical trials for patients with this condition.
Cretostimogene Grenadenorepvec is being developed by CG Oncology, Inc., a biopharmaceutical company traded on the stock exchange under the ticker symbol CGON.
Cretostimogene Grenadenorepvec is in Phase 2 and Phase 3 clinical trials. It has received Fast Track and Breakthrough Therapy designations from the FDA, but it is not yet approved and remains investigational.
Cretostimogene Grenadenorepvec is being studied in three clinical trials: NCT04452591, a Phase 3 study in NMIBC unresponsive to Bacillus-Calmette-Guerin; NCT06111235, a Phase 3 adjuvant study in intermediate-risk NMIBC; and NCT06567743, a Phase 2 study in high-risk NMIBC.
Cretostimogene Grenadenorepvec is also known by the name CG0070. Both names refer to the same investigational gene therapy being developed by CG Oncology for non-muscle-invasive bladder cancer.
