Study Overview

Brief Summary

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.

Detailed Description

Anti-myeloma bridging treatment is allowed for disease control while bb2121 is being manufactured.

Inclusion Criteria

  • 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.
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or
  • Subjects must have measurable disease, including at least one of the criteria below:
  • 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.

Exclusion Criteria

  • The presence of any of the following will exclude a subject from enrollment:
  • Subjects with known central nervous system involvement with myeloma.
  • History or presence of clinically relevant central nervous system (CNS) pathology.
  • Subjects with active or history of plasma cell leukemia.
  • Subjects with solitary plasmacytomas or non-secretory myeloma without other evidence of measurable disease
  • Inadequate organ function
  • Ongoing treatment with chronic immunosuppressants
  • Previous history of an allogeneic hematopoietic stem cell transplantation or treatment with any gene therapy-based therapeutic for cancer or investigational cellular therapy for cancer or BCMA targeted therapy

  • Seropositive for and with evidence of active viral infection with hepatitis B virus (HBV)
  • Seropositive for and with evidence of active viral infection with hepatitis B virus (HBV) and Hepatitis C virus (HCV)
  • Subjects with a history of class III or IV congestive heart failure (CHF) or severe non-ischemic cardiomyopathy, history of stroke, unstable angina, myocardial infarction, or ventricular arrhythmia within the previous 6 months.
  • Subjects with second malignancies in addition to myeloma if the second malignancy has required therapy in the last 3 years or is not in complete remission
  • Pregnant or lactating women.
  • Subject with known hypersensitivity to any component of bb2121 productThe presence of any of the following will exclude a subject from enrollment:
  • Subjects with known central nervous system involvement with myeloma.
  • History or presence of clinically relevant central nervous system (CNS) pathology.
  • Subjects with active or history of plasma cell leukemia.
  • Subjects with solitary plasmacytomas or non-secretory myeloma without other evidence of measurable disease

  • Subjects with a history of class III or IV congestive heart failure (CHF) or severe non-ischemic cardiomyopathy, history of stroke, unstable angina, myocardial infarction, or ventricular arrhythmia within the previous 6 months.
  • Subjects with second malignancies in addition to myeloma if the second malignancy has required therapy in the last 3 years or is not in complete remission
  • Pregnant or lactating women. 13 Subject with known hypersensitivity to any component of bb2121 product, cyclophosphamide, fludarabine, or tocilizumab.
