Study Description

The purpose of this study is to evaluate the efficacy and safety of rapcabtagene autoleucel versus comparator in participants with severe active Granulomatosis with Polyangiitis (GPA) or Microscopic Polyangiitis (MPA) This is a Phase 2, 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 comparator.

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.
