Assessing CHO-H01 for Non-Hodgkin's Lymphoma Treatment

A Phase I/IIa, Open-label, Multicenter Study of the Safety and Efficacy of CHO-H01 as a Single Agent/Combined With Lenalidomide to Subjects With Refractory or Relapsed Non-Hodgkin's Lymphoma

Phase1; Phase2 Interventional Cho Pharma Inc. · NCT05950165

This study is testing a new treatment called CHO-H01 for people with relapsed or hard-to-treat non-Hodgkin's lymphoma to see if it is safe and effective when combined with another medication.

What this trial studies

This clinical trial evaluates the safety and efficacy of CHO-H01, a glyco-engineered anti-CD20 antibody, in patients with relapsed or refractory CD20+ non-Hodgkin's lymphoma. The study is divided into two phases: Phase 1 focuses on determining the maximum tolerated dose and safety profile of CHO-H01, while Phase 2a assesses its anticancer activity when combined with lenalidomide. Participants will receive CHO-H01 via IV infusion, with treatment cycles lasting up to 19 weeks. The study aims to provide a new therapeutic option for patients with low-grade lymphoma.

Who should consider this trial

Good fit: Ideal candidates include adults with histologically confirmed CD20+ non-Hodgkin's lymphoma who have a life expectancy of more than 12 weeks and meet specific health criteria.

Not a fit: Patients with non-CD20+ non-Hodgkin's lymphoma or those who are currently receiving other treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new effective option for patients with relapsed or refractory non-Hodgkin's lymphoma.

How similar studies have performed: Other studies involving anti-CD20 antibodies have shown promising results, indicating potential success for this novel approach.
