What this trial studies

This multicenter, single-arm, open-label study aims to assess the safety and efficacy of Prizloncabtagene Autoleucel (Prizlon-cel) in patients with relapsed or refractory large B-cell lymphoma. The study consists of two phases: Phase 1b focuses on determining the recommended Phase 2 dose (RP2D), while Phase 2 evaluates the treatment's efficacy. Participants will undergo a series of procedures including screening, apheresis for CAR-T manufacturing, lymphodepletion, and CAR-T infusion, followed by a minimum of two years of follow-up. Long-term follow-up may extend up to 15 years in a separate study.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with histologically confirmed CD19 or CD20 positive B-cell non-Hodgkin lymphoma who have relapsed or refractory disease after multiple lines of therapy.

Not a fit: Patients who have undergone prior allogeneic hematopoietic stem cell transplantation or autologous stem cell transplantation within 12 weeks prior to apheresis 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 large B-cell lymphoma.

How similar studies have performed: Other studies have shown promising results with CAR-T therapies for similar conditions, indicating a potential for success with this approach.
