简要总结
The purpose of this trial is to evaluate the efficacy and safety of obecabtagene autoleucel (obe-cel) administered once following lymphodepletion in participants with severe, refractory systemic lupus erythematosus (SLE) and active lupus nephritis (LN).
详细描述
This is a Phase 2 study to determine the efficacy and safety of obe-cel in participants with severe, refractory SLE with active LN.
The study comprises 3 periods:
- Screening Period: From Day -30 (+7) to Day of Enrollment
- Treatment Period: From Day -8 to Day 1 - Participants will be evaluated to confirm eligibility for lymphodepletion, and thereafter receive lymphodepletion.
Obe-cel Administration: If the participant's eligibility for receiving obe-cel infusion is confirmed, the participant is to receive a single obe-cel infusion on Day 1. 3. Post-treatment Period: From Day 1 to End of Study all participants will be followed up for efficacy and safety evaluation.

入选标准
- •Willing and able to give written informed consent for participation in the study or written informed consent signed by a legal guardian or representative
- •Ability and willingness to adhere to protocol's Schedule of Activities and other requirements
- •Participants must be 12 to 65 years of age inclusive at the time of signing the informed consent.
- •Female Participants: - a female participant is eligible to participate if she is not pregnant or breastfeeding
- •Diagnosis of SLE fulfilling the 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) Classification Criteria for Systemic Lupus Erythematosus.
- •Positive for at least 1 of the following autoantibodies: antinuclear antibodies (ANA), or anti-dsDNA or anti-Smith.
- •Severe, Active SLE defined as:
- •SLEDAI-2K score of ≥ 8 points AND
- •Severe active LN based on a renal biopsy: Class III, IV or V (V only in combination with class III or IV)
- •Refractory SLE defined as failure to previous lines of therapy
排除标准
- •Prior treatment at any time with anti-CD19 therapy
- •More than 1 acute, severe lupus-related flare during screening that needs immediate treatment and/or makes the immunosuppressive washout impossible
- •Significant, likely irreversible organ damage related to SLE (e.g., end-stage renal disease) that in the opinion of the Investigator renders CD19 CAR T cell therapy unlikely to benefit the participant
- •History of primary antiphospholipid antibody syndrome
- •Active or uncontrolled fungal, bacterial, or viral infection
- •History of malignant neoplasms unless disease free for at least 24 months
- •History of heart, lung, renal, liver transplant or hematopoietic stem cell transplant
