Multiple Myeloma Clinical Trial
A Study of Whether Ide-cel (bb2121) Can Be Made From People With Multiple Myeloma Who Have Had a Hematopoietic Cell Transplant
The purpose of this study is to see if the quality of T cells used to create ide-cel (bb2121) affects how ide-cel prevents cancer from coming back in people with relapsed or refractory multiple myeloma (MM), and who have had a hematopoietic cell transplant.

Prior to LD Chemotherapy
Females of childbearing potential must have a negative serum pregnancy test ≤ 7 days prior to LD chemotherapy
Platelet count ≥ 50,000/mm^3 (transfusion allowed)
ANC ≥ 1,000/mm^3 (without filgrastim within 72 hours)
Serum AST and ALT ≤ 2.5 × ULN
Serum total bilirubin ≤ 2 × ULN. Patients who have been diagnosed with Gilbert's disease are permitted to exceed the defined bilirubin value of 2 x ULN
CrCl ≥ 45 mL/min, measured or estimated by Cockcroft-Gault equation
INR or PTT ≤ 1.5 x ULN
No history of ≥ Grade 2 hemorrhage within 30 days
No presence of active/uncontrolled infection requiring systemic therapy. Prophylactic antimicrobials are allowed.
No intercurrent illness or toxicity that would place the subject at undue risk of proceeding to LD chemotherapy
Must not be taking therapeutic doses of corticosteroids (defined as greater than 10 mg/day prednisone or equivalent) within 72 hours prior to LD chemotherapy. Physiologic replacement, topical, intranasal and inhaled steroids are permitted. Patients on calcineurin inhibitors (cyclosporine or tacrolimus) should have levels considered undetectable per institutional criteria
No active urinary outflow obstruction
Availability of manufactured cells
Patients not meeting these criteria may still be eligible to initiate LD chemotherapy with the approval of the Protocol PI (Principal Investigator).
Prior to Ide-Cel or Cilta-Cel infusion
Subjects who meet at least one of the following criteria on the day of scheduled CAR T cell infusion should have its administration delayed:
Suspected or active systemic infection
Onset of fever ≥ 38°C
Requirement for supplemental oxygen to keep saturation greater than 91%
Cardiac arrhythmia not controlled with medical management
Hypotension requiring vasopressor support
New onset or worsening of other non-hematologic organ dysfunction ≥ Grade 3
Taking any of the prohibited medications as described in Section 15
Significant worsening in clinical status compared to initial eligibility criteria that would, in the opinion of the treating physician, increase the risk of adverse events associated with Ide-Cel or Cilta-Cel infusion.
Receiving any of the following less than 14 days prior to enrollment:
Major surgery (as defined by the investigator)
Radiation therapy other than local therapy for MM-associated bone lesions
Prior organ transplant requiring systemic immunosuppressive therapy

Active clinically significant autoimmune disease, defined as a history of requiring systemic immunosuppressive therapy and at ongoing risk for potential disease exacerbation. Patients with a history of autoimmune thyroid disease, asthma, or limited skin manifestations are potentially eligible. Patients with a history of acute or chronic GVHD are potentially eligible if on minimal immunosuppressants as defined previously.

Unable or unwilling to return to the center for treatment and follow up
No systemic anti-myeloma therapy is allowed within 7 days prior to leukapheresis. Steroids are allowed, but should be tapered off by 72 hours prior to leukapheresis.
