Recurrent Plasma Cell Myeloma Refractory Plasma Cell Myeloma | Drug: Carfilzomib Drug: Dexamethasone Biological: Isatuximab Drug: Pomalidomide | Phase 2 |
OUTLINE:
INDUCTION: Patients receive isatuximab intravenously (IV) on days 1, 8, 15, and 22 of cycle 1 and days 1 and 15 of subsequent cycles carfilzomib IV over 30 minutes on days 1, 8, and 15, pomalidomide orally (PO) once daily (QD) on days 1-21, and dexamethasone PO or IV on days 1,8, 15, and 22. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity.
MAINTENANCE: Patients receive isatuximab IV days 1 and 15, carfilzomib IV over 30 minutes on days 1 and 15, pomalidomide PO QD on days 1-21, and dexamethasone PO or IV on days 1, 8, 15, and 22. Cycles repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then for up to 5 years.

- Overall response rate [ Time Frame: Up to 5 years post treatment ]Responses will be based on the International Myeloma Working Group criteria for response in multiple myeloma.
- Progression-free survival (PFS) [ Time Frame: From first study drug administration to the first occurrence of disease progression or death from any cause, assessed up to 5 years ]PFS will be calculated using assessments by investigators. Kaplan-Meier methodology will be used to estimate event-free curves and corresponding quartiles (including the median).
- Overall survival [ Time Frame: From the first study drug administration to death from any cause, assessed up to 5 years ]Kaplan-Meier methodology will be used to estimate the event-free curves.
- Time to progression [ Time Frame: Up to 5 years post treatment ]
- Incidence of adverse events [ Time Frame: Up to 30 days post treatment ]Will be measured by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.
- Rates of minimal residual disease negativity [ Time Frame: Up to 5 years post treatment ]Measured by next-generation sequencing of immunoglobulin genes in the bone marrow.
