Overview
RESET-SLE: A Phase 1/2 Open-Label Study to Evaluate the Safety and Efficacy of CABA-201 in Subjects With Active Systemic Lupus Erythematosus
Description
Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder characterized by autoantibody production and abnormal B cell function. SLE presents with fluctuating severity and may cause tissue damage in a variety of organs over time. Lupus nephritis (LN) (renal involvement) is a common severe manifestation of SLE, which can lead to significant morbidity and mortality. This study is being conducted to evaluate the safety and efficacy of an investigational cell therapy, CABA-201, that can be given to patients with either LN or SLE without renal involvement, in two separate parallel cohorts, who have active disease. A single dose of CABA-201 in patients who are pretreated with a standard regimen including cyclophosphamide (CY) and fludarabine (FLU) will be evaluated.
Eligibility
Inclusion Criteria:
- Age ≥18 and ≤65
- A clinical diagnosis of SLE, based on the 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for adult SLE.
- Positive antinuclear antibody (ANA) titer or anti-dsDNA antibody at screening.
- For LN subjects only, active, biopsy-proven LN class III or IV, with or without the presence of class V, according to 2018 Revised International Society of Nephrology/Renal Pathology Society (ISN/RPS) criteria
- For non-renal SLE subjects only: Active, moderate to severe SLE
Exclusion Criteria:
- Contraindication to leukapheresis
- History of anaphylactic or severe systemic reaction to fludarabine, cyclophosphamide or any of their metabolites
- Active infection requiring medical intervention at screening
- Current symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, pulmonary, psychiatric, cardiac, neurological, or cerebral disease, including severe and uncontrolled infections, such as sepsis and opportunistic infections.
- Concomitant medical conditions that, in the opinion of the investigator, might place the subject at unacceptable risk for participation in this study, interfere with the assessment of the effects or safety of the investigational product or with the study procedures
- For LN subjects only: The presence of kidney disease other than active lupus nephritis
- Previous CAR T cell therapy
- Prior solid organ (heart, liver, kidney, lung) transplant or hematopoietic cell transplant.
