This study is an open-label dose escalation study (Phase 1a) to investigate the safety and toxicity of intravesical treatment of high-grade NMIBC (HGTa or CIS, including CIS with concomitant Ta) after transurethral resection of bladder tumor (TURBT) and/or biopsy using TARA-002 in adults unable to obtain intravesical Bacillus Calmette-Guérin (BCG), adults who have received at least one dose of intravesical BCG or adults who have received at least one dose of intravesical chemotherapy. Dosing will start in subjects with HGTa or CIS (including CIS with concomitant Ta) NMIBC to include a minimum of 1 dosing cohort and a maximum of 3 total dosing cohorts. All subjects will receive 6 weeks of treatment at a fixed volume with varying dose levels.
