A Phase 2, Open-Label, Single-Arm Trial of FT819 in Participants With Lupus Nephritis

Starting soon · Phase 2

Conditions studied: Lupus Nephritis, Systemic Lupus Erythematosus, SLE - Systemic Lupus Erythematosus, Lupus Nephritis - WHO Class III, Lupus Nephritis - WHO Class IV

In brief

The primary objective of this trial is to evaluate the efficacy and safety of FT819, comprised of allogeneic T cells that express a CD19-targeted CAR, following bendamustine administration in participants with refractory moderate-to-severe lupus nephritis, as assessed by the proportion of participants who achieve complete renal response (CRR) at Week 26.

Who can join

Age: 12 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥12 to ≤70 years
• Diagnosis of SLE per EULAR/ACR 2019 classification criteria
• Biopsy-proven proliferative Class III or IV LN, with or without concomitant Class V involvement, based on the 2003/2018 ISN/RPS classification
• Positivity for at least one of the following autoantibodies at screening:
• Antinuclear antibody (ANA)
• Anti-double-stranded DNA (anti-dsDNA) or
• Anti-Smith antibody
• Active disease, defined as:
• a. Evidence of SLE activity, defined as either: i. SLEDAI-2K ≥6 or ii. At least 1 BILAG A or 2 BILAG B scores for SLE-related organ involvement; and b. Evidence of renal involvement, defined as UPCr ≥1 g/g; and c. Moderate-to-severe renal disease with investigator's impression that improvement is possible
• Refractory to ≥2 systemic immunosuppressive therapies for the treatment of LN

You may not qualify if…

• Evidence of inadequate organ function during the screening period
• Active central nervous system (CNS) symptoms attributable to autoimmune disease within 12 months prior to trial intervention
• History of or current renal diseases (other than LN) that, in the opinion of the investigator, could interfere with assessment of LN or confound evaluation of disease activity
• Receipt of dialysis (hemodialysis or peritoneal dialysis) within 12 weeks of trial intervention
• Irreversible organ damage related to underlying disease (e.g., ESRD) where, in the opinion of the investigator, CD19 CAR T-cell therapy would be unlikely to benefit the participant
• History of malignancy in the prior 5 years
• Known allergy to the following FT819 components: albumin (human) or DMSO
• History of intolerance or contraindication to bendamustine
• Body weight <30 kg
• Any medical condition, clinical laboratory abnormality, or nonmedical/social issue that, per investigator or medical monitor judgement, precludes safe participation in and completion of the trial or that could affect compliance with protocol conduct or interpretation of results
