Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 12 to 70 with moderate to severe active B-cell mediated autoimmune diseases who have not responded to at least two prior treatments.
✕Probably not a fit
Patients with severe organ dysfunction, recent cancer, or those who are pregnant or breastfeeding may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This phase 1 study aims to assess the safety, pharmacokinetics, and anti-B-cell activity of FT819 in patients with moderate to severe active autoimmune diseases, including systemic lupus erythematosus, ANCA-associated vasculitis, idiopathic inflammatory myositis, and systemic sclerosis. The study will involve a dose-escalation phase followed by an expansion phase to further evaluate the treatment's safety and efficacy. Participants will receive FT819, with or without auxiliary medicinal products, to determine the optimal dosing and therapeutic effects.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat autoimmune diseases.
How similar studies have gone: While this approach is novel, similar studies targeting B-cell mediated autoimmune diseases have shown promise in the past.
