Primary Outcome Measures:
  • To assess the progression free survival (PFS) for pomalidomide and dexamethasone in patients who have relapsed and are refractory to lenalidomide and have previously been treated with bortezomib [ Time Frame: 2 year ]

Secondary Outcome Measures:
  • To assess Overall Response Rate (ORR) [ Time Frame: 2 year ]
  • To see if addition of cyclophosphamide with induce additional response in patient who do not achieve an minimal response (MR) after 3 months [ Time Frame: 2 year ]
  • To assess Overall Survival (OS) [ Time Frame: 5 year ]
  • To assess Duration of Response (DOR) [ Time Frame: 2 year ]
  • To assess Safety and Tolerability [ Time Frame: 2 year ]

Estimated Enrollment: 15
Study Start Date: November 2014
Estimated Study Completion Date: November 2018
Estimated Primary Completion Date: August 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pomalidomide and Dexamethasone

PO pomalidomide 4mg from D1-21 and PO dexamethasone 40mg D1, 8, 15 and 22 in a 28-day cycle.

PO or IV cyclophosphamide 300mg/m2 on D1, 8 and 15 can be added at the discretion of the treating physician to induce added response under the following circumstances: 1) If there is less than a MR after 3 cycles in the absence of disease progression, or 2) If there is disease progression within the first 3 cycles of Pomalidomide and Dexamethasone treatment.

Patients will be assessed every 28 days (+/-10 days). Patients shall receive the treatment until disease progression, unacceptable toxicity as determined by treating physician, withdrawal of consent or mortality (whichever occurs first).

Drug: Pomalidomide and Dexamethasone
Pomalidomide will be given at 4mg once daily for 21 days in a 28-day cycle. Dexamethasone will be given at a dose of 40mg orally once a week for 4 weeks (D1,8,15,22).

Detailed Description:

Myeloma patients who relapse after prior treatment with bortezomib and lenalidomide have survival of less than 1 year. Recently, a randomized study of Pomalidomide and dexamethasone conducted in compared with placebo and dexamethasone showed that pomalidomide can improve survival of this group of patients.

Pomalidomide is a new immunomodulatory drug which has been shown to be active in myeloma patients who relapse after bortezomib and lenalidomide. A recent phase III study comparing pomalidomide plus dexamethasone with placebo plus high dose dexamethasone in patients with prior exposure to bortezomib and lenalidomide, showed that the use of pomalidomide significantly improve the overall survival of these patients. However, this study did not include Asian patients. Therefore the efficacy and toxicity of pomalidomide remains to be described in Asian patients
