P-CD19CD20-ALLO1 for B-Cell Malignancies

This study is testing a new immunotherapy called P-CD19CD20-ALLO1, which uses special immune cells (CAR-T cells) to fight certain B-cell cancers. It's for people aged 18 and older who have specific types of B-cell lymphoma, such as Diffuse Large B-Cell Lymphoma (DLBCL) or Follicular Lymphoma Grade 3B, that have returned or are not responding to other treatments. The main goal is to find the safest dose of P-CD19CD20-ALLO1 and understand any side effects. You would receive P-CD19CD20-ALLO1 as a single intravenous (IV) infusion, and you might also receive another drug called Rimiducid. This study is currently enrolling 120 participants.

Study design
This is a Phase 1 study with two parts: a dose-escalation phase to find the maximum tolerated dose (MTD) and an expansion phase. It is an open-label study, meaning both you and your doctors will know what treatment you are receiving.
What's involved
After joining, you will receive lymphodepletion therapy before a single IV administration of P-CD19CD20-ALLO1. Your safety, tolerability, and response will be measured regularly.
Compensation
Not stated in the trial record.
Follow-up
Your safety will be assessed from baseline through 28 days after treatment.
