PeproMene Bio's PMB-CT01 demonstrates deep remission in B-cell lymphomas even after CD19 CAR-T failure
Executive summary: PeproMene Bio published Phase 1 trial results in The Lancet for its PMB-CT01 therapy, which targets BAFF-R in B-cell lymphomas. The therapy showed deep and lasting complete responses in patients who were unresponsive to previous CD19-targeted CAR-T cell treatments.
Who is involved: PeproMene Bio, The Lancet (medical journal), and patients with relapsed/refractory B-cell lymphomas.
Likely next: Transitioning to Phase 2 clinical trials and potential discussions for strategic partnerships or further funding.
PeproMene Bio has published Phase 1 clinical trial results in The Lancet, showing that its BAFF-R-targeted CAR-T therapy, PMB-CT01, can achieve durable complete responses in patients with relapsed or refractory B-cell lymphomas. Notably, the therapy showed efficacy in patients who had previously failed standard CD19-targeted CAR-T treatments. This finding positions the company as a potential leader in addressing unmet needs within the CAR-T landscape.
