Description
This is a Phase 2, two-year, randomized, assessor- blinded, active-controlled study. This study comprises two cohorts:
* A lead-in cohort enrolling participants to receive rapcabtagene autoleucel
* A randomized cohort with participants receiving either rapcabtagene autoleucel or a comparator option.
After end of study (EOS), participants who received rapcabtagene autoleucel infusion will enter a long-term follow-up (LTFU) period lasting up to 15 years after rapcabtagene autoleucel infusion. This LTFU will be described in a separate study protocol.
