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


This phase II trial studies the effect of isatuximab, carfilzomib, and pomalidomide in treating patients with multiple myeloma that has come back (relapsed) or does not respond to treatment (refractory). Isatuximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as pomalidomide, 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 isatuximab, carfilzomib, and pomalidomide may help treat patients with multiple myeloma.

Am I Eligible?

The following criteria is a partial list of reasons why patients may or may not be eligible to participate in this clinical trial. Further evaluation with a medical professional will be required to determine full eligibility.

The following criteria is provided for health care professionals.

Inclusion Criteria:

  • Participant or legally authorized representative (LAR) must provide written informed consent before any study specific procedures or interventions are performed

  • Relapsed or refractory multiple myeloma, defined as meeting one or more of the following:
    • Nonresponsive to most recent therapy (stable disease or progressive disease [PD] while on treatment), or
    • Disease progression within 60 days of discontinuation from most recent therapy
  • Participant has received at least 1 line of prior therapy.
    • Prior exposure to proteasome inhibitor is permitted, with a 2 week washout period from last dose
    • Prior exposure to immunomodulatory imide drug (IMiD) is permitted, with a 2 week washout period from last dose
    • Prior treatment with anti-CD38 therapy (e.g., daratumumab) is permitted, following a 6 month washout period from last dose
  • Measurable disease with at least one of the following:
    • Monoclonal immunoglobulin spike on serum protein electrophoresis of >= 0.5 g/dL
    • Urine monoclonal immunoglobulin spike of >= 200 mg/24 hours
    • Involved free light chain (FLC) >= 10 mg/dL and an abnormal serum FLC ratio (i.e., < 0.26 or > 1.65)
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 50%)
  • Toxicity related to prior therapies that, in the opinion of the investigator, would potentially be worsened with anti-CD38 therapy should be resolved to baseline or less than grade 1
  • Anticipated life expectancy of at least 6 months (per investigator discretion)
  • No contraindication to receiving thromboprophylaxis for pomalidomide
  • Patients must have normal marrow and organ function as defined by:
    • Absolute neutrophil count >= 1,000/uL
    • Platelets >= 75,000/uL
    • Hemoglobin concentration of >= 8.0 g/dL within 14 days prior to registration. Patients may have received transfusion if greater than 7 days prior to registration
    • Must have adequate liver function, as defined by:
      • Total bilirubin =< 2 x institutional upper limits of normal (IULN)
      • Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) =< 2 x IULN
    • Must have adequate renal function, as defined by:
      • Creatinine clearance (CrCl) of >= 30 mL/min, as measured by a 24-hour urine collection or as estimated by the Cockcroft and Gault formula. The serum creatinine value used in the calculation must have been obtained within 35 days prior to registration.
      • For patients with a creatinine clearance within the range of 30-45 mL/min, stability (i.e., not deteriorating) must be demonstrated over a period of 8 weeks prior to enrollment in the study
  • Left ventricular ejection fraction (LVEF) by echocardiogram >= 40% within 35 days prior to initiating study treatment
  • Women of childbearing potential must have a negative serum or urine pregnancy test within 14 days prior to receiving the first dose of study medication. If the urine pregnancy test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
  • Female participants of childbearing potential (FOCBP) must agree to use highly-effective method(s) of contraception during the study and for 3 months after the last dose of study drug. FOCBP are those who have not been surgically sterilized or have not been free from menses for > 1 year without an alternative medical cause
  • Male participants must agree to use an adequate method of contraception starting with the first dose of study therapy through 3 months after the last dose of study drug

Exclusion Criteria:
