Evaluating SC291 for severe autoimmune diseases

A Phase 1 Study Evaluating SC291, a Hypoimmune, Allogeneic CD19-directed CAR T Cell Therapy, in Subjects With Severe Relapsed or Refractory Autoimmune Diseases (GLEAM)

Phase 1 Interventional Sana Biotechnology · NCT06294236

This study is testing a new cell therapy called SC291 to see if it is safe and helps people with severe autoimmune diseases like lupus and vasculitis who haven't responded to other treatments.

What this trial studies

This Phase 1 study aims to assess the safety and tolerability of SC291, an investigational cell therapy, in patients with severe autoimmune diseases such as systemic lupus erythematosus (SLE) and anti-neutrophil cytoplasmic antibody-associated vasculitis. Participants will be divided into cohorts based on their specific conditions, including lupus nephritis and extrarenal lupus, and will have previously shown refractory disease to standard treatments. The study will involve a single dose of SC291 administered after a standard pretreatment regimen. The primary focus is to evaluate preliminary clinical responses and cellular kinetics.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 75 with severe systemic lupus erythematosus or anti-neutrophil cytoplasmic antibody-associated vasculitis who have refractory disease.

Not a fit: Patients who have previously received CD19-directed cell therapy or genetically modified cell therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with severe autoimmune diseases that have not responded to existing therapies.

How similar studies have performed: While the approach of using cell therapy for autoimmune diseases is being explored, this specific investigational therapy is novel and has not been extensively tested in similar studies.
