|Official Title:||Phase II Trial of High Dose Lenalidomide in Patients With Myelodysplastic Syndrome Refractory to Hypomethylating Agents|
|Study Start Date :||June 2011|
|Actual Primary Completion Date :||May 2014|
|Actual Study Completion Date :||August 2015|
Lenalidomide 50 mg/day for two 28 day cycles.
Patients who have bone marrow aplasia as defined by a cellularity of <10% will be observed till counts recover. If patients do not progress following 2 cycles of HD lenalidomide, they will receive low dose lenalidomide 10 mg daily for 12 cycles.
Other Name: Revlimid
- Number of Participants With Confirmed Responses (Complete Remission, Partial Remission, or Hematologic Improvement) as Defined by the International Working Group Criteria [ Time Frame: Up to 56 weeks (14 cycles of treatment) ]
- Complete remission (CR): ≤5% myeloblasts bone marrow blasts, normal maturation in all cell lines (dysplasia will be noted), ≥11 g/dl peripheral blood hemoglobin, ≥100x10^9cells/μL peripheral blood platelets, ≥1000 cells/ μL peripheral blood absolute neutrophil count (ANC), and 0% peripheral blood blasts.
- Marrow complete remission (MCR): ≤5% myeloblasts and decreased by ≥50% compared to pre-treatment bone marrow blasts, bone marrow morphology not relevant, and peripheral blood (if hematological improvement they will be noted in addition to marrow CR).
- Partial remission (PR): previously had ≥5% myeloblasts and now have ≥5% myeloblasts but decreased by ≥50% compared to pre-treatment, bone marrow morphology not relevant, ≥11 g/dl peripheral blood hemoglobin, ≥100x109cells/μL peripheral blood platelets, ≥1000 cells/ μL peripheral blood ANC, and 0% peripheral blood blasts
- Overall Survival Rate [ Time Frame: 6 months after end of treatment (up to 82 weeks from start of treatment) ]-Overall survival rate is the percentage of participants who were alive 6 months after end of treatment.
- Duration of Response [ Time Frame: Until 6 months after end of treatment ]
- Time to Discontinuation of Treatment [ Time Frame: Up to 56 weeks (14 cycles) ]
- Toxicity as Measured by Number of Participants Who Experienced Related Grade 3-5 Adverse Events Based on CTCAE Version 4 [ Time Frame: 30 days after end of treatment (up to 60 weeks) ]
- Time to Progression [ Time Frame: Up to 6 months after completion of treatment (up to 82 weeks from start of treatment) ]The time to progression is defined as the time from registration to the date of progression or last follow-up. Those who die will be considered to have had disease progression unless documented evidence clearly indicates no progression has occurred.
