Purpose

Study CRB-402 is a 2-part, non-randomized, open label, multi-site Phase 1 study of bb21217 in adults with relapsed/refractory multiple myeloma (MM).

Detailed Description

      Part A of the study will be Dose Escalation followed by Part B, an expansion cohort.

      Following consent, enrolled subjects will undergo a leukapheresis procedure to collect
      autologous mononuclear cells for manufacture of investigational drug product (bb21217).
      Following manufacture of the drug product, subjects will receive lymphodepletion prior to
      bb21217 infusion. All subjects will then be followed for up to 60 months in Study CRB-402.

      All subjects who complete the study, as well as those who withdraw from the study after
      receiving bb21217 for reasons other than death or meeting the early termination criteria,
      will be asked to continue to undergo long-term follow-up in a companion study.

Eligibility Criteria

        Inclusion Criteria:

          -  ≥18 years of age at the time of signing informed consent

          -  Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1

          -  Diagnosis of MM with relapsed or refractory disease and have had at least 3 different
             prior lines of therapy with previous exposure to PI, IMiDs, and a CD38 antibody. Have
             undergone at least 2 consecutive cycles of treatment for each therapy, unless PD was
             the best response to the therapy. Refractory to their last line of therapy.

          -  Subjects must have measurable disease

        Exclusion Criteria:

          -  Subjects with known central nervous system disease

          -  Inadequate hepatic function

          -  Inadequate renal function

          -  Inadequate bone marrow function

          -  Presence of active infection within 72 hours

          -  Subjects with a history of stroke, unstable angina, myocardial infarction, or
             ventricular arrhythmia requiring medication or mechanical control

          -  Significant co-morbid condition or disease which in the judgment of the Investigator
             would place the subject at undue risk or interfere with the study; examples include,
             but are not limited to, cirrhotic liver disease, sepsis, recent significant traumatic
             injury, and other conditions

          -  Known human immunodeficiency virus (HIV) positivity

          -  Known hepatitis A virus (HAV), hepatitis B virus (HBV) or hepatitis C virus (HCV)
             positivity with evidence of ongoing infection.

          -  Pregnant or lactating women

          -  Previous history of an allogeneic bone marrow transplantation, treatment with any gene
             therapy based therapeutic for cancer, or BCMA-targeted therapy

          -  Inadequate pulmonary function defined as oxygen saturation (SaO2) <92% on room air

          -  Subjects who have a history of plasma cell leukemia, active plasma cell leukemia,
             Waldenstrom's macroglobulinemia, POEMS, or clinically significant amyloidosis
