Evaluating GLPG5101 for treating Non-Hodgkin Lymphoma

A Phase I/II, Multicenter Study Evaluating the Feasibility, Safety, and Efficacy of Point-of-care Manufactured GLPG5101 (19CP02) in Subjects With Relapsed/Refractory B-cell Non-Hodgkin Lymphoma

Phase1; Phase2 Interventional Galapagos NV · NCT06561425

This study is testing a new treatment called GLPG5101 to see if it can help people with relapsed or hard-to-treat B-cell Non-Hodgkin Lymphoma feel better and stay safe during treatment.

What this trial studies

This study evaluates the safety and efficacy of an experimental treatment called GLPG5101 in patients with relapsed or refractory B-cell Non-Hodgkin Lymphoma (NHL). It consists of two phases: the first phase focuses on determining the optimal doses with minimal side effects, while the second phase involves administering the selected doses to different cohorts based on NHL subtypes. Participants will be monitored for efficacy and safety outcomes throughout the trial.

Who should consider this trial

Good fit: Ideal candidates include individuals with histologically confirmed relapsed or refractory B-cell Non-Hodgkin Lymphoma, including various subtypes such as DLBCL, FL, MZL, and MCL.

Not a fit: Patients with non-relapsed or non-refractory forms of Non-Hodgkin Lymphoma or those who do not meet the eligibility criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat forms of Non-Hodgkin Lymphoma.

How similar studies have performed: Other studies have shown promise in treating Non-Hodgkin Lymphoma with novel therapies, suggesting that this approach could be beneficial.
