Sponsored by CG Oncology, Inc. · Expanded access
This is an open-label, expanded access trial designed to provide access to cretostimogene in patients with NMIBC (specifically CIS with or without HG Ta/T1) unresponsive to BCG.
All participants will be assigned the same treatment schedule. Participants will receive an induction course of 6 weekly treatments, and, if there is no disease recurrence at Week 13, participants will receive a cycle of 3 weekly treatments up to Week 15.
If there is persistent HG Ta and/or CIS at Week 13, participants may receive a second induction cycle.
If the participant has persistent but improved HG Ta and/or CIS at Week 25 or a later timepoint, the participant may receive a cycle of 3 weekly treatments of cretostimogene at the discretion of the Investigator provided that T1 or higher stage of urothelial carcinoma is not present.
If there is no disease present at Week 25 or a later timepoint, participants will receive a cycle of 3 weekly treatments every 12 weeks through Month 12.
After Month 12, participants will receive a cycle of 3 weekly treatments every 6 months through the last treatment cycle at Month 24, or until discontinuation from the study treatment.
Disease status will be assessed based on local standard of care (which may include urine cytology, cystoscopy, and directed TURBT/biopsy) every 12 weeks. CTU/MRU can be done per standard of care evaluation at investigator's discretion.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
