Disease: Relapsed/Refractory Multiple Myeloma, MM, (NCT04171843)
Multiple myeloma is a cancer that develops in the bone marrow, the spongy tissue found in the centre of most bones. Multiple myeloma is characterized by abnormalities in plasma cells, a type of white blood cell. These abnormal cells multiply out of control, increasing from about one percent of cells in the bone marrow to the majority of bone marrow cells. The abnormal cells form tumours within the bone, causing bone pain and an increased risk of fractures.
Multiple myeloma occurs in approximately 4 per 100,000 people per year; there are currently about 100,000 affected individuals in the United States.
A Phase 1/2a, Open-label, Dose-escalation, Dose-expansion Study to Evaluate the Safety and Clinical Activity of PBCAR269A, With or Without Nirogacestat, in Study Participants With Relapsed/Refractory Multiple Myeloma
PBCAR269A is an allogeneic 'off-the-shelf' CAR T therapy. Using T cells derived from healthy donors as starting material, then utilizes the ARCUS genome editing technology to modify the cells via a single-step engineering process. By inserting the CAR gene at the T cell receptor (TCR) locus, this process knocks in the CAR while knocking out the TCR, creating a cell product that is designed to prevent graft-versus-host disease.

Phase III Safety and Efficacy
Status: Active recruiting
This is a multicenter, nonrandomized, open-label, parallel assignment, single-dose, dose-escalation, and dose-expansion study to evaluate the safety and clinical activity of PBCAR269A in adults with r/r Multiple Myeloma
Before initiating the study treatment PBCAR269A, all study participants will be administered lymphodepletion chemotherapy. The initial lymphodepletion chemotherapy regimen will be composed of fludarabine and cyclophosphamide during the Screening Period. On Day 0 of the Treatment Period, study participants will receive a single intravenous (IV) infusion of PBCAR269A. All subjects are monitored during the treatment period through Day 28. All subjects who receive a dose of PBCAR269A will be followed in a separate long-term follow-up (LTFU) study for 15 years after exiting this study.
