The purpose of this study is to evaluate the efficacy and safety of rapcabtagene autoleucel (administered once following lymphodepletion) versus Standard of Care (SOC) in patients with systemic lupus erythematosus (SLE) with active, refractory lupus nephritis (LN).
A Study of Rapcabtagene Autoleucel in Systemic Lupus Erythematosus (SLE) Patients With Active, Refractory Lupus Nephritis (LN)

Study details
Inclusion Criteria
- . Participant must be positive for at least one of the following autoantibodies at screening: antinuclear antibodies (ANA) at a titer of >= 1:80 (on HEp-2 cells or an equivalent positive test), or anti-dsDNA (above the ULN); or anti-Sm (above the ULN) as determined by a central laboratory.
- 2. Active lupus nephritis without signs of significant chronicity
- SLEDAI-2K Criteria at screening: SLEDAI-2K score >= 6 points (Gladman et al 2002, Touma et al 2011), excluding points attributed to "fever", "lupus headache", "alopecia", and "organic brain syndrome".
Exclusion Criteria
- Any acute, severe lupus related-flare at screening that needs immediate treatment other than pulse GCs and/or makes the immunosuppressive washout impossible and, thus, makes the participant ineligible for CD19 CAR-T therapy
- Inadequate organ function during screening and prior to randomization
- History or current diagnosis of ECG or cardiac abnormalities indicating significant risk of safety for participants prior to randomization
Study Requirements
This is a Phase 2, adaptive, two-year, randomized, assessor-blinded, active controlled study: Part A: Participants suffering from systemic lupus erythematosus (SLE) with active, refractory LN will be randomized to Regimen 1, Regimen 2, or SOC. Part B: Participants suffering from SLE with active, refractory LN will be randomized to the selected regimen from Part A or SOC. The study will consist of two periods: A screening period lasting up to 6 weeks, and A randomized treatment period and primary follow-up period lasting up to 104 weeks. 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.
