Evaluating AT101 for patients with relapsed B-cell Non-Hodgkin's Lymphoma

An Open-label, Single-arm, Multi-center, Phase I/II Study to Evaluate the Safety, Tolerability, and Efficacy of AT101 (Anti-CD19 Chimeric Antigen Receptor T Cell) in Patients With Relapsed or Refractory B-cell Non-Hodgkin's Lymphoma

Phase1; Phase2 Interventional AbClon · NCT05338931

This study is testing a new treatment called AT101 to see if it can help people with relapsed B-cell non-Hodgkin's lymphoma feel better and how safe it is.

What this trial studies

This clinical trial aims to assess the safety, tolerability, and efficacy of AT101, an anti-CD19 chimeric antigen receptor T cell therapy, in patients with relapsed or refractory B-cell non-Hodgkin lymphoma. The study will determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) for this patient population. Participants will be monitored for their response to the treatment and any adverse effects experienced during the trial.

Who should consider this trial

Good fit: Ideal candidates include individuals with B-cell non-Hodgkin lymphoma who have not responded to standard therapies or have experienced disease progression.

Not a fit: Patients who have previously undergone allogeneic hematopoietic stem cell transplantation or those with certain contraindications to the treatment may not benefit from this study.

Why it matters

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

How similar studies have performed: Previous studies involving CAR T-cell therapies have shown promising results in treating various types of lymphoma, indicating potential success for this novel approach.
