4. Subjects must have documented diagnosis of multiple myeloma and have measurable disease (serum M-protein ≥ 1.0 g/dL or urine M-protein ≥ 200 mg/24 hours). However, for subjects with IgA multiple myeloma, a serum M-protein of ≥ 0.5 g/dL or urine M-protein ≥ 200 mg/24 hours will be eligible for the study.
5. Subjects must have undergone prior treatment with ≥ 2 treatment lines of anti-myeloma therapy. Induction therapy followed by ASCT and consolidation/maintenance will be considered as one line.
6. Subjects must have either refractory or relapsed and refractory disease defined as documented disease progression during or within 60 days of completing their last myeloma therapy.
• Primary refractory: Subjects who have never achieved any response better than PD to any previous line of anti-myeloma therapy.
• Relapsed and refractory: Subjects who have relapsed after having achieved at least stable disease for at least two cycles of treatment to at least one prior regimen and then developed PD on or within 60 days of completing their last myeloma therapy.
7. All subjects must have received at least 2 consecutive cycles of prior treatment that included lenalidomide and bortezomib, either alone or in combination regimens as follows in criterion # 8.
8. Medical records must be available that provide documentation of the following criteria for refractoriness that make the subject eligible for the study:
• All subjects must have failed treatment with both lenalidomide and bortezomib as follows:
- Documented PD during or within 60 days of completing treatment with lenalidomide and/or bortezomib, or
- In case of prior response (≥ PR) to lenalidomide or bortezomib, subjects must have relapsed within 6 months after stopping treatment with lenalidomide and/or bortezomib-containing regimens, or
- Subjects who have not had a ≥ MR response and have developed intolerance/toxicity after a minimum of two cycles of lenalidomide- and/or bortezomib-containing regimen:
• Bortezomib-containing regimen: a toxicity such as > grade 2 peripheral neuropathy or ≥ grade 2 painful neuropathy. Peripheral neuropathy must resolve to grade 1 prior to study entry.
• Lenalidomide-containing regimen: a toxicity which led to permanent discontinuation of lenalidomide, such as grade 4 rash. Rash must resolve to ≤ Grade 1 prior to study entry.
• Patients must have received adequate prior alkylator therapy either as part of ASCT or a minimum of 6 cycles of an alkylator based therapy.
9. Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2.
10. Females of childbearing potential (FCBP) must agree to refrain from becoming pregnant for 28 days prior to initiation of study drug, while on study drug and for 28 days after discontinuation from the study drug and must agree to regular pregnancy testing during this timeframe.
11. Females must agree to abstain from breastfeeding during study participation and 28 days after study drug discontinuation.
12. Males must agree to use a latex condom during any sexual contact with FCBP while participating in the study and for 28 days following discontinuation from this study, even if he has undergone a successful vasectomy.
13. Males must also agree to refrain from donating semen or sperm while on pomalidomide and for 28 days after discontinuation from this study treatment.
14. All subjects must agree to refrain from donating blood while on study drug and for 28 days after discontinuation from this study treatment.
15. All subjects must agree not to share medication. |
