A Study of Whether Ide-Cel (bb2121) Can Be Made From People with Relapsed or Refractory Multiple Myeloma who have had a Hematopoietic Cell Transplant
This phase II trial tests whether Ide-cel or Cilta-Cel work to improve blood test results in patients with multiple myeloma that has come back (relapsed) or does not respond to treatment (refractory) and have a hematopoietic cell transplant. Ide-cel injection is in a class of medications called autologous cellular immunotherapy, a type of medication prepared using cells from the patient's own blood. It works by causing the body's immune system (a group of cells, tissues, and organs that protects the body from attack by bacteria, viruses, cancer cells, and other substances that cause disease) to fight the cancer cells. Ide-cel is made by genetically modifying (changing deoxyribonucleic acid [DNA]/genes) T cells to help them identify, fight, or kill cancer cells. T cells are part of the immune system, the body’s defense against infections and diseases. T cells are a type of white blood cell that help fight infections. Ide-cel may be more effective at preventing cancer from coming back.

Estimate the feasibility of manufacturing Ide-Cel or Cilta-Cel (to dose of at least 300 million cells) in patients who have 1.) measurable disease prior to salvage autologous (auto) hematopoietic cell transplantation (HCT) from cryopreserved stem cells collected during initial therapy or 2.) have measurable disease after prior allogeneic (allo)HCT for multiple myeloma (MM).
SECONDARY OBJECTIVES:
I. Estimate the overall response rate (ORR) of Ide-Cel at 12 months post Ide-Cel or Cilta-Cel.
II. Estimate the progression free (PFS) and overall survival (OS) after infusion.
