Elotuzumab, Pomalidomide, & Dexamethasone (Elo-Pom-Dex) With Second Autologous Stem Cell Transplantation for Relapsed Multiple Myeloma

This is an interventional treatment trial for Multiple Myeloma in Relapse Read More

Inclusion Criteria:

• Histologically confirmed diagnosis of multiple myeloma.
• Received prior autologous stem cell transplantation as first line therapy for multiple myeloma with subsequent disease relapse/progression.
• Failed 1 or 2 lines of treatment for multiple myeloma. A line of treatment includes all therapy including induction, transplant, and maintenance administered in a sequence in the absence of relapse/progression. Once relapse/progression occurs and subsequently the anti-myeloma treatment is changed, a new line of treatment has begun. Local radiation or corticosteroids will not be considered treatment for multiple myeloma.
• Received 2 to 6 cycles of induction therapy per standard of care prior to 2nd autologous stem cell transplantation
• Received standard of care melphalan conditioning for 2nd autologous stem cell transplantation, is currently Day +80 to +120 following transplant, and is responding to therapy (partial response or better as compared to pre-induction assessment.
• All US study participants must be registered into the mandatory POMALYST REMS® program and be willing and able to comply with the requirements of the POMALYST REMS® program. For Canadian sites, patients will followed according to the Pomalidomide pregnancy prevention program
• Females of reproductive potential within the US must agree to adhere to the scheduled pregnancy testing as required in the POMALYST REMS® program. For Canadian sites, patients will followed according to the Pomalidomide pregnancy prevention program
• At least 18 and no more than 75 years of age at enrollment.
• Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2

• Normal bone marrow and organ function as defined as ALL of the following:

  • Absolute neutrophil count ≥ 1000/mm^3
  • Platelets ≥ 75,000/mm^3 (transfusions not permitted within 7 days of screening)
  • Total bilirubin ≤ 2.0 x institutional upper limit of normal (IULN)
  • AST(SGOT)/ALT(SGPT) ≤ 3.0 x IULN
  • Creatinine clearance ≥ 15 mL/min
• Females of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry through Day +100 visit. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.
• Able to understand and willing to sign an Institutional Review Board (IRB) approved written informed consent document.

Exclusion Criteria:

• Refractory to elotuzumab and/or pomalidomide, defined as progressive disease or clinical relapse on therapy or within 60 days following completion of therapy. Prior exposure to elotuzumab and/or pomalidomide is allowed as long as patient is not refractory to these agents.
• More than one prior transplant prior to study entry with the exception of tandem transplantation. Tandem transplantation is defined as two autologous stem cell transplants that occur within 9 months of one another, and the patient did not have disease progression in the period between the two transplants.
• Presence of peripheral neuropathy ≥ grade 3 based on National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v 4.0
• History of plasma cell leukemia or MM central nervous system (CNS) involvement.
• Receiving renal replacement therapy, hemodialysis, or peritoneal dialysis.
• Diagnosed with another concurrent malignancy requiring treatment.
• Known HIV or active hepatitis A, B, or C. Antidoby testing not required for screening
• Known hypersensitivity to pomalidomide, dexamethasone, or any excipients in elotuzumab, formulation, or recombinant protein
• Receiving any other investigational agents within 14 days prior to enrollment.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia.
• Pregnant and/or breastfeeding. Females of childbearing potential must have two negative pregnancy tests. The first test should be performed within 10-14 days of study entry, and the second test within 24 hours prior to prescribing pomalidomide.
