研究概览
简要总结
The goal of the present study is to assess, through a randomized phase II trial, the efficacy and safety of Lenalidomide with or without Epoetin beta in transfusion-dependent, ESA-resistant, IPSS low and intermediate-1 risk MDS patients without chromosome 5 abnormality.
Patients will receive either Lenalidomide alone or Lenalidomide and Epoetin beta for 4 months. Responders will be eligible for maintenance treatment with cycles identical to the first cycles, until relapse occurs or until unacceptable toxicity.
详细描述
This is a multi-center, open-label, randomized, Phase II study.
Patients will be treated either with arm A or B
- Arm A: Lenalidomide 10 mg/day for 21 days every 28 days for 4 courses.
- Arm B: Lenalidomide 10 mg/day for 21 days every 28 days for 4 courses combined with weekly subcutaneous injections of Epoetin beta (60,000 Units/w).
Evaluation of response at the end of 4 months according to IWG 2006 and IWG 2000 criteria.
Maintenance: responders will continue to follow the corresponding treatment arm until relapse occurs; non responders at Evaluation of response at the end of 4 months according to IWG 2006 and IWG 2000 criteria.

研究组 & 干预措施
Arm A
Lenalidomide 10 mg/day for 21 days every 28 days for 4 courses.
Evaluation of response at the end of 4 months according to IWG 2006 and IWG 2000 criteria.
Maintenance: responders will continue to follow the corresponding treatment arm until relapse occurs; non responders at cycle 4 in arm A will be considered in failure of treatment and the introduction of Epoetin beta is at the discretion of the physician.
The patients will be followed every 3 months for 12 months
干预措施: Lenalidomide (Drug)
Arm B
Lenalidomide 10 mg/day for 21 days every 28 days for 4 courses combined with weekly subcutaneous injections of Epoetin beta (60,000 Units/w).
Evaluation of response at the end of 4 months according to IWG 2006 and IWG 2000 criteria.
Maintenance: responders will continue to follow the corresponding treatment arm until relapse occurs; non responders at cycle 4 in arm A will be considered in failure of treatment and the introduction of Epoetin beta is at the discretion of the physician.
The patients will be followed every 3 months for 12 months
干预措施: Epoetin beta (Drug)
结局指标
主要结局
Comparing the efficacy of Lenalidomide alone to Lenalidomide with Epoetin beta in transfusion-dependent ESA-resistant
时间窗: After 4 months of treatment
Primary outcome is a complete or partial response defined by the IWG 2006 criteria observed after 4 months of treatment. Comparison in the rate of response between the two groups will be performed with Chi-square test or if necessary Fisher exact test. Same analyzes will be performed with the IWG 2000 response definition .
次要结局
- will be to assess the safety of Lenalidomide and of its combination with Epoetin beta(After 2 months of treatment)
