Autologous Stem Cell Transplant With Pomalidomide (CC-4047®) Maintenance Versus Continuous Clarithromycin/ Pomalidomide / Dexamethasone Salvage Therapy in Relapsed or Refractory Multiple Myeloma

Completed · Phase 2

Conditions studied: Multiple Myeloma

In brief

The purpose of this study is to see whether pomalidomide (also known as Pomalyst) reduces the number of myeloma cells in the bones, and to see what is the best way to use pomalidomide in patients with myeloma. To do this, the investigators want to compare two types of treatment using pomalidomde. This is a randomized trial which means that the decision as to which treatment the patient will receive will be made by a computer, much like flipping a coin. All patients start by receiving 4 cycles of clarithromycin, pomalidomide and dexamethasone (ClaPD). After 4 cycles, half of the patients will undergo an autologous stem cell transplant followed by pomalidomide (Group 1). The other half of the patients will continue to receive ClaPD for 9 cycles to be followed by pomalidomide maintenance. (Group 2). At the end of the study, the two groups will be compared to see if there is a difference in disease outcome.

You may qualify if…

Patients must have histologically or cytologically confirmed relapsed multiple myeloma as defined by the International Myeloma Working Group (IMWG).
Patients must have measurable disease as defined by the International Uniform Response Criteria, defined as any of the following:
serum M-protein of ≥ 500mg/dL
urine M-protein of ≥ 200mg/ 24 hours
involved free light chain ≥ 10mg/dL provided serum free light chain ratio is abnormal
Patients must have had a previous auto-SCT performed as part of a consolidation of an initial remission and had a remission, defined as a partial response or greater that lasted at least 12 months either on or off maintenance therapy without evidence of progression as defined by IMWG criteria.
Patients who are post auto-SCT as primary therapy must have received maintenance therapy with lenalidomide.
Patients must be registered within 6 months of last dose of lenalidomide.
Minimum of 3 months of maintenance therapy prior to disease progression.
Age ≥ 18 years.
Life expectancy of ≥12 weeks.
KPS ≥ 70 or ECOG < 1 (Appendix IV)
Patients must have adequate organ and marrow function as defined below:
ANC ≥ 750/μL
Platelets≥ 50,000/μL
Total bilirubin ≤ 1.5 mg/dL
AST(SGOT) ≤ 3 X upper limit of normal.
ALT(SGPT) ≤ 3 X upper limit of normal.
Cardiac Ejection Fraction ≥ 40%
Serum Creatinine ≤ 2.0 mg/dL
Patients must have an adequate number of CD34+ stem cells collected to allow for transplantation (defined as ≥ 2x10\^6 CD34+ cells / kg body weight). If not previously collected and stored or if previous collection was inadequate, the patient must be willing to undergo stem cell mobilization and collection as per standard practice.
Patients who participate in this study must be willing and able to tolerate prophylactic anticoagulation either with aspirin, low-molecular weight heparin (LMWH), or warfarin.
Ability to understand and the willingness to sign a written informed consent document.
Patient must be determined fit to undergo auto-SCT procedure by a study physician.
Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the POMALYST REMS™ program. Females of childbearing potential (FCBP)† must have a negative serum or urine pregnancy test with a sensitivity of at least 25 mIU/mL within 10 - 14 days and again within 24 hours prior to prescribing pomalidomide (prescriptions must be filled within 7 days) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking pomalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure.

You may not qualify if…

Patients who have had myeloma therapy within 14 days prior to entering the study or those who have not recovered from adverse events due to agents administered more than 2 weeks earlier. Patients may have received bisphosphonate therapy or radiation therapy as part of routine myeloma care at any time prior to study entry.
Patients may not be receiving any other investigational agents.
Any prior use of thalidomide or pomalidomide.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to lenalidomide (including thalidomide) clarithromycin, or melphalan.
Known prior positivity for active HIV or infectious hepatitis, type B or C.
Uncontrolled illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure , unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Pregnant and lactating women are excluded from the study because the risks to an unborn fetus or potential risks in nursing infants are unknown.
History of thrombosis or thromboembolic event within last 30 days prior to study entry.
Patients with CNS involvement.
