NCT06048250

Brief Summary

This phase I trial studies the safety, side effects, best dose and effectiveness of mezigdomide (CC-92480) when given after idecabtagene vicleucel (Abecma chimeric antigen receptor \[CAR\] T-cell therapy) in patients with multiple myeloma that has come back after a period of improvement (relapsed). CC-92480 works by binding to a protein called CRBN that triggers the breakdown of proteins: Ikaros and Aiolos, leading to cell death in multiple myeloma cells. Giving mezigdomide after Abecma CAR T cell therapy may extending the amount of time that the CAR T cells persist in the body in patients with relapsed multiple myeloma.

Outcome Measures

Primary Outcomes (1)

  • Incidence of adverse events

    Will be assessed by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 (NCI CTCAE v 5.0). Observed toxicities will be summarized in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study treatment and reversibility or outcome.

    Up to 2 years

Secondary Outcomes (6)

  • Overall response rate

    Up to 2 years

  • Complete response rate

    Up to 2 years

  • Overall survival

    From first day of treatment to time of death due to any cause, assessed up to 2 years

  • Progression free survival

    From first day of treatment to the first observation of disease progression or death due to any cause, assessed up to 2 years

  • Time to progression

    From first day of treatment to the first observation of disease progression or death due to disease, assessed up to 2 years

  • +1 more secondary outcomes

Study Arms (1)

Treatment (mezigdomide)

EXPERIMENTAL

Starting between 30 and 90 days after infusion of idecabtagene vicleucel, patients receive mezigdomide PO on days 1-21 or days 1-14 of each cycle. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo PET/CT during screening. Patients also undergo bone marrow aspiration and blood sample collection throughout the study.

  • Age: \>= 18 years
  • Eastern Cooperative Oncology Group (ECOG) =\< 2
  • Diagnosis of multiple myeloma
  • Subject must have received at least 4 prior lines of therapy, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody
  • Subject must have experienced at least a stable disease in response to idecabtagene vicleucel
  • Fully recovered from the acute toxic effects (except alopecia) to =\< grade 1 to prior anti-cancer therapy, including idecabtagene vicleucel
  • Absolute neutrophil count (ANC) \>= 1,500/mm\^3 without the use of filgrastim in the previous 3 days (To be performed within 14 days prior to day 1 of protocol therapy unless otherwise stated)
