CAR20(NAP)-T therapy for B-cell lymphoma

A Phase I/IIa Multicenter Study Evaluating the Safety and Efficacy of CAR20(NAP)-T in Patients With Relapsed/Refractory B Cell Lymphoma (CARMA-01 Study)

Phase1; Phase2 Interventional Uppsala University · NCT06002659

This study is testing a new treatment that uses modified immune cells to help people with B-cell lymphoma fight their cancer better, especially for those who haven't had success with other treatments.

What this trial studies

This study investigates the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of CAR20(NAP)-T therapy in patients with B-cell malignancies. The therapy involves engineering a patient's T cells to express a chimeric antigen receptor that targets CD20, aiming to enhance the immune response against tumor cells. By secreting a bacterial-derived immune-stimulating factor, NAP, the treatment seeks to counteract antigen escape and improve therapeutic outcomes for patients who have not responded to existing therapies.

Who should consider this trial

Good fit: Ideal candidates include adults with relapsed or refractory CD20+ B-cell lymphoma who have received at least two lines of therapy and are not eligible for CD19-directed CAR T cell treatment.

Not a fit: Patients with B-cell lymphoma who are not CD20 positive or who have not undergone prior therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option for patients with relapsed or refractory B-cell lymphoma who have limited alternatives.

How similar studies have performed: Other studies targeting CD20 in B-cell malignancies have shown promise, but the specific approach of using CAR20(NAP)-T is novel and has not been extensively tested.
