Treatment for patients with relapsed or refractory B-Cell Non-Hodgkin Lymphoma

A Phase 1/2, Open-Label, Multicenter Trial Investigating the Safety, Tolerability, and Preliminary Antineoplastic Activity of IPH6501 in Patients With Relapsed and/or Refractory CD20-expressing Non-Hodgkin Lymphoma

Phase1; Phase2 Interventional Innate Pharma · NCT06088654

This study is testing a new treatment called IPH6501 to see if it can help people with advanced B-cell non-Hodgkin lymphoma who have already tried other options.

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.

Who should consider this trial

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.

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.

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