Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with relapsed/refractory primary ITP or primary wAIHA who meet safety criteria and consent to the procedure.

Probably not a fit

Patients who have contraindications to CAR-T therapy or who do not respond to CTX112 may not experience meaningful benefit.

What this trial studies

This is a multicenter, open-label, single-arm Phase 1/2 study evaluating the safety and early signals of efficacy for CTX112 (zugo-cel) in adults with relapsed or refractory primary ITP or primary wAIHA. CTX112 is an allogeneic CD19-targeted CAR-T cell product derived from healthy donors and modified ex vivo. The study explores ascending dose levels to identify tolerability and potential clinical benefit, with up to 60 participants over up to five years. Primary endpoints focus on safety, with secondary endpoints examining preliminary efficacy and disease activity markers.

Why it matters

Potential benefit: If successful, participants may experience reduced disease activity and improved blood counts after a single CAR-T treatment.

How similar studies have gone: Preliminary data from similar anti-CD19 CAR-T approaches in autoimmune diseases have shown activity, supporting further investigation.
