• Any additional malignancy that requires active treatment, unless deemed appropriate after discussion by the Investigator with the trial's Medical Monitor.
• Chronic active hepatitis B or C and HIV.

• Meet the following histopathologic requirements for urothelial carcinoma:
  • For Cohorts 1b, 4a-c:
  • histopathological diagnosis of NMIBC (any grade) is required. For participants with first diagnosis of NMIBC, confirmation of urothelial carcinoma by recent biopsy (≤6 months of Screening Visit) is required. Participants with recurrent NMIBC must have a current lesion that clinically appears to be NMIBC with histopathologic confirmation based on TURBT or biopsy within the last 24 months).
  • For Cohorts 4d, 4e, 4g and 4h, a diagnosis of LG IR NMIBC (according to
  • AUA risk classification guidelines) is required, specifically:
  • Multifocal LG Ta; OR
  • Solitary LG Ta >3 cm; OR
  • Low-grade Ta with prior recurrence(s) within 1 year.
  • For Cohorts 4f and 4i, a diagnosis of HR NMIBC (according to AUA risk classification guidelines) is required, specifically:
  • Ta HG papillary disease with or without CIS; OR
  • T1 papillary disease with or without CIS
  • Participants may be BCG-naïve or may have received prior treatment with BCG for HR or IR NMIBC (BCG-exposed, BCG-failed, BCG-intolerant)
  • BCG-refractory participants are excluded. BCG-refractory is defined by the following:
  • Persistent HG disease at 6 months following adequate BCG (defined as ≥5/6 induction instillations and ≥2 additional doses, either from re-induction or maintenance), OR
  • HG T1 disease at first evaluation (3 months) after BCG, OR
  • Persistent CIS that remains despite a second BCG course, OR
  • Disease progression in stage or grade during BCG therapy, including maintenance
• Have no evidence of current or prior metastatic urothelial carcinoma
• Adequate bone marrow, renal, and hepatic function
