1. Must be = 18 years at the time of signing the informed consent form.
2. The subject must understand and voluntarily sign an informed consent document prior to any study related assessments/procedures are conducted. The only exception is if a skeletal survey was performed within 60 days prior to the start of Cycle 1, a new survey will not be required.
3. Must be able to adhere to the study visit schedule and other protocol requirements.
4. Subjects must have documented diagnosis of multiple myeloma and have measurable disease (serum M-protein = 0.5 g/dL or urine Mprotein = 200 mg/24 hours).
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 # 9.
8. Subjects must have received adequate prior alkylator therapy in one of the following ways:
•As part of a stem cell transplant or
•a minimum of 6 consecutive cycles of an alkylator based therapy or
•progression on treatment with an alkylator, provided that the patient received at least 2 cycles of an alkylator-containing therapy.
9.All subjects must have failed both lenalidomide and bortezomib and 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 the last lenalidomidecontaining regimen in one of the following ways:
-Documented PD during or within 60 days of completing treatment with lenalidomide, or
-In case of prior response (= PR) to lenalidomide, subjects must have relapsed within 6 months after stopping treatment with lenalidomidecontaining regimens
•All subjects must have failed treatment with the last bortezomibcontaining regimen in one of the following ways:
-Documented PD during or within 60 days of completing treatment with bortezomib, or
-In case of prior response (= PR) to bortezomib, subjects must have relapsed within 6 months after stopping treatment with bortezomibcontaining regimens, or
-Subjects who have not had a = MR response and have developed
intolerance/toxicity after a minimum of two cycles of a bortezomibcontaining regimen. For example, a toxicity such as > grade 2 peripheral neuropathy or = grade 2 painful neuropathy. Peripheral neuropathy must resolve to g
1. Any of the following laboratory abnormalities:
• Absolute neutrophil count (ANC) < 1,000/µL
• Platelet count < 75,000/ µL for subjects in whom < 50% of bone
marrow nucleated cells are plasma cells; or a platelet count < 30,000/
µL for subjects in whom =50% of bone marrow nucleated cells are
plasma cells
• Creatinine Clearance <45mL/min according to Cockcroft-Gault formula
(See Appendix I). If creatinine clearance calculated from the 24-hour
urine sample is =45mL/min, patient will qualify for the trial.
• Corrected serum calcium > 14 mg/dL (> 3.5 mmol/L)
• Hemoglobin < 8 g/dL (< 4.9 mmol/L; prior RBC transfusion or
recombinant human erythropoietin use is permitted)
• Serum SGOT/AST or SGPT/ALT > 3.0 x upper limit of normal (ULN)
• Serum total bilirubin >2.0mg/dL (34.2µmol/L); or >3.0xULN for
subjects with hereditary benign hyperbilirubinaemia.
2. Prior history of malignancies, other than MM, unless the subject has
been free of the disease for =5years. Exceptions include the following:
• Basal or Squamous cell carcinoma of the skin
• Carcinoma in situ of the cervix or breast
• Incidental histologic finding of prostate cancer (TNM stage of T1a or
T1b)
3. Previous therapy with Pomalidomide.
4.Hypersensitivity to thalidomide, lenalidomide, or dexamethasone.
(This includes = Grade 3 rash during prior thalidomide or lenalidomide
therapy.)
5. Resistance to high-dose dexamethasone used in the last line of
therapy: Defined as disease progression on or within 60 days of
receiving the last dose of high-dose dexamethasone used in the last line
of therapy, either as single agent or in combination. Subjects who
progressed on low-dose dexamethasone will qualify for the trial.
6. Peripheral neuropathy = Grade 2.
7. Subjects who received an allogeneic bone marrow or allogeneic
peripheral blood stem cell transplant less than 12 months prior to
initiation of study treatment and who have not discontinued
immunosuppressive treatment for at least 4 weeks prior to initiation of
study treatment and are currently dependant on such treatment.
8. Subjects who are planning for or who are eligible for stem cell
transplant.
9. Subjects with any one of the following:
• Congestive heart failure (NY Heart Association Class III or IV)
• Myocardial infarction within 12 months prior to starting study
treatment
• Unstable or poorly controlled angina pectoris, including Prinzmetal
variant angina pectoris
10. Subjects who received any of the following within the last 14 days of
initiation of study treatment:
• Plasmapheresis
• Major surgery (kyphoplasty is not considered major surgery)
• Radiation therapy
• Use of any anti-myeloma drug the
