Treatment Sequencing in Patients who Progress Beyond CAR T in Early Relapse MM

Opinion
Video

Focusing on a clinical scenario in which a patient receives early-line CAR T-cell therapy and relapses, Surbhi Sidana, MD, shares insights on treatment sequencing and the role of bispecific antibodies.

Case: A 60-Year-Old Woman with Later Relapsed/Refractory Multiple Myeloma

Clinical Presentation:

  • A 60-year-old woman who was previously diagnosed 3 years ago with R-ISS stage 2/R2-ISS stage III IgG-lambda multiple myeloma presents to his oncologist after two prior treatment regimens.
    • Lives in a rural community

Prior Treatments:

  • Patient received previous treatments with:
    • D-VRd followed by ASCT with lenalidomide maintenance.
    • Elo-Pd

Follow up and Clinical Workup at Relapse:

  • Ca 12.5 mg/dL; SCr 2.5 mg/dL
  • Hgb 8.2 g/dL; LDH 290 U/L; Albumin 2.8 g/dL
  • Beta-2 microglobulin: 6 mg/dL
  • BM Biopsy: 65% lambda light chain restricted.
  • sIFE, IgG lambda present
  • M protein 5.2 g/dL; sFLC kappa 5 mg/dL; sFLC lambda 560 mg/dL
  • Lambda/Kappa ratio, 112
  • Repeat Imaging:
    • PET/CT scan showed no additional lesions.
  • ECOG PS
  • After discussion with her clinical team, the patient begins evaluations for CAR T referral.
    • Patient ultimately proceeded to ide-cel CAR T-cell infusion.
      • Achieved stringent CR at day 30.

Video content above is prompted by the following question:

  • How would you approach treatment sequencing in patients who progress beyond CAR T in early relapse MM?
