Isatuximab, Carfilzomib, Pomalidomide, and Dexamethasone for the Treatment of Relapsed or Refractory Multiple Myeloma

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. All patients undergo bone marrow aspirate and biopsy during screening, skeletal x-ray, computed tomography (CT), positron emission tomography (PET)-CT, or magnetic resonance imaging (MRI), bone marrow and blood sample collection throughout the study. After completion of study treatment, patients are followed up at 30 days, then for up to 5 years.
