Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with advanced, histologically confirmed CD20+ B-cell non-Hodgkin lymphoma who have received at least two prior systemic therapies.

Probably not a fit

Patients with another invasive malignancy in the last two years or those who have not received prior anti-CD20 antibody therapy may not benefit from this study.

What this trial studies

This international, first-in-human, multicenter Phase 1/2 study evaluates the safety and tolerability of IPH6501 in patients with advanced CD20+ B-cell non-Hodgkin lymphoma. The study consists of a dose-finding Phase 1, which includes dose escalation to determine the Maximum Tolerated Dose (MTD) and a recommended Phase 2 dose (RP2D). In Phase 2, selected cohorts of patients with specific subtypes of the disease will receive the treatment to assess its efficacy. The study aims to provide a new therapeutic option for patients with limited treatment alternatives.

Why it matters

Potential benefit: If successful, this treatment could offer a new option for patients with relapsed or refractory B-cell non-Hodgkin lymphoma who have exhausted other therapies.

How similar studies have gone: Other studies utilizing NK cell engagers have shown promise, indicating potential for success in this novel approach.
