A Phase IIa Study of ICG318 CAR-T in Refractory Systemic Lupus Erythematosus With or Without Lupus Nephritis

Sponsored by iCell Gene Therapeutics

About this study

This Phase IIa, open-label, single-arm study includes an initial Safety Run-In followed by dose expansion to evaluate the safety, tolerability, cellular kinetics, pharmacodynamics, and preliminary clinical activity of a single infusion of ICG318 in participants with refractory SLE, with or without LN. Participants will receive protocol-specified lymphodepletion followed by ICG318 at the recommended Phase 2 dose.

Systemic Lupus Erythematosus (SLE) is a multisystem, chronic autoimmune disease that may impact multiple organs including the joints, skin, kidney, heart, brain and lungs, with severity ranging from mild to life-threatening. Lupus Nephritis (LN) is the most prevalent and severe form of SLE with high morbidity and mortality and persistent relapses despite current therapies. SLE, with or without LN is driven largely by pathogenic autoantibodies produced by CD19 expressing B cells and BCMA expressing plasma cells, including long-lived plasma cells. ICG318, the investigational agent in this clinical trial is an armored, compound chimeric antigen receptor (CAR) composed of two independently functioning CARs that simultaneously target the B-cell CD19 surface antigen and the plasma cell/ long l…
