What was measured

Number of participants positive to anti-cetrelimab antibodies was reported using validated immunoassay for anti-drug antibody (ADA) analysis.

Analysis population: FAS included all enrolled participants who received at least 1 dose of study treatment. Here "N" (overall number of participants analyzed) signifies number of participants evaluable for this outcome measure. This OM was planned to be analyzed for Cohorts 1 and 3 only.

Groups in this outcome

Cohort 1: TAR-200 + Cetrelimab (CIS With or Without Papillary Disease)

Participants with CIS with or without papillary disease, received TAR-200 intravesically every 3 weeks (Q3W) from Week 0 for the first 24 weeks, followed by every 12 weeks (Q12W) dosing through Week 99 in combination with cetrelimab 360 milligrams (mg) intravenously (IV) Q3W from Week 0 through Week 78. TAR-200 was inserted intravesically via the urinary placement catheter (UPC).

Cohort 3: Cetrelimab IV Monotherapy (CIS With or Without Papillary Disease)

Participants with CIS with or without papillary disease, received cetrelimab 360 mg IV Q3W from Week 0 through Week 78.
