NCT03502577

Brief Summary

This phase I trial determines the side effects and best dose of B-cell maturation antigen (BCMA)-chimeric antigen receptor (CAR) T-cells when combined with gamma-secretase inhibitor LY3039478 (JSMD194), cyclophosphamide, and fludarabine in treating participants with multiple myeloma that that has come back or remains despite treatment. Placing genes added in the laboratory into immune T-cells may make the T-cells recognize BCMA, a protein on the surface of cancer cells. JSMD194 may enhance the killing of cancer cells by increasing the BCMA expression on multiple myeloma cells, making the targeted BCMA CAR-T treatment more effective. JSMD194 also decreases the amount of BCMA found in the circulation (called soluble BCMA) that is not bound to the myeloma cells. JSMD194 can therefore reduce the potential for soluble BCMA to act as a decoy. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving BCMA CAR T therapy with JSMD194, cyclophosphamide, and fludarabine may work better in treating participants with relapsed or persistent multiple myeloma.

Outcome Measures

Primary Outcomes (2)

    Up to 28 days following CAR T-cell infusion

  • Incidence of general toxicities

    This will be measured according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0.

    Up to 1 year

Secondary Outcomes (5)

  • Objective response rate of complete remission and partial remission

    Up to 1 year

  • Progression-free survival

    Up to 1 year

  • Overall survival

    Up to 1 year

  • Duration of persistence of adoptively transferred B-cell maturation antigen (BCMA) CAR T cells

    Up to 1 year

  • Evaluation of the migration of adoptively transferred BCMA CAR T cells

Other Outcomes (1)

  • Plasma cell BCMA expression and soluble (s)BCMA levels with LY3039478 administration

    Up to 1 year

Study Arms (1)

Treatment (Chemotherapy, BCMA-specific CAR T-cells, LY3039478)

EXPERIMENTAL

Participants receive fludarabine and cyclophosphamide on days -4 to -2. Participants then receive BCMA-specific CAR T-cells IV over 20-30 minutes on day 0 and LY3039478 PO on days 2, 4, 7, 9, 11, 14, 16, and 18.
