Japanese Phase 1 Study to Evaluate Tolerated Dose, Safety, and Efficacy of Pomalidomide in Patients With Refractory or Relapsed and Refractory Multiple Myeloma
- Registration Number
- NCT01568294
- Lead Sponsor
- Celgene
- Brief Summary
The purpose of this study is to determine the tolerated dose of pomalidomide and also to evaluate the pharmacokinetics, safety and efficacy of pomalidomide in patients with refractory or relapsed and refractory multiple myeloma.

- All
- Target Recruitment
- 12
-
Must be ≥ 20 years of age at the time of signing the informed consent document
-
The subject must understand and voluntarily sign an informed consent document prior to any study related assessments/procedures are conducted.
-
Must be able to adhere to the study visit schedule and other protocol requirements
-
Subjects must have documented diagnosis of multiple myeloma and have measurable disease
-
All subjects must have had at least 2 prior lines of anti-myeloma therapy. Induction therapy followed by stem cell transplant and consolidation/maintenance will be considered as one line
-
All subjects must have either refractory or relapsed and refractory disease defined as documented disease progression during or within 60 days of completing their last anti-myeloma therapy.
- Primary refractory: Subjects who have never achieved any response better than progressive disease (PD) to any previous line of anti-myeloma therapy.
- Relapsed and refractory: Subjects who have relapsed after having achieved at least stable disease (SD) to at least one prior regimen and then developed progressive disease (PD) on or within 60 days of completing their last anti-myeloma therapy.
-
Subjects must have also undergone prior treatment with at least 2 cycles of lenalidomide and at least 2 cycles of bortezomib (either in separate regimens or within the same regimen).
-
All subjects must have received adequate prior alkylator therapy.

- Creatinine Clearance < 45 mL/min according to Cockcroft-Gault formula
- 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)

Peripheral neuropathy ≥ Grade 2
-
Patients 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 therapy
