Efficacy and Safety Study of bb2121 in Subjects With Relapsed and Refractory Multiple Myeloma

Completed · Phase 2

Conditions studied: Multiple Myeloma

In brief

This is an open label, single-arm, multicenter, Phase 2 study to evaluate the efficacy and safety of bb2121 in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture bb2121 chimeric antigen receptor (CAR) modified T cells. Prior to bb2121 infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Eligibility is determined prior to leukapheresis. Subjects must satisfy the following criteria to be enrolled in the study:
• Subject is ≥ 18 years of age at the time of signing the informed consent form (ICF).
• Documented diagnosis of multiple myeloma
• Must have received at least 3 prior MM treatment regimens. Note: induction with or without hematopoietic stem cell transplant and with or without maintenance therapy is considered a single regimen.
• Must have undergone at least 2 consecutive cycles of treatment for each regimen, unless PD was the best response to the regimen.
• Must have received a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 antibody.
• Must be refractory to the last treatment regimen.

• Serum M-protein greater or equal to 1.0 g/dL
• Urine M-protein greater or equal to 200 mg/24 h
• Serum free light chain (FLC) assay: involved FLC level greater or equal to 10 mg/dL (100 mg/L) provided serum FLC ratio is abnormal
• Recovery to Grade 1 or baseline of any non-hematologic toxicities due to prior treatments, excluding alopecia and Grade 2 neuropathy.
