简要总结
The purpose of this study is to:
- Test the safety of the research study drug, lenalidomide, when given with Idarubicin and Cytarabine
- See how many respond to combination treatment with lenalidomide, Idarubicin and Cytarabine
- See how long people respond to this combination therapy
- See how long people live after being treated with this combination of drugs
详细描述
All three drugs are FDA approved to treat patients in the United States of America. Idarubicin and Cytarabine combination therapy is a standard treatment for patients with acute myeloid leukemia (AML). Lenalidomide is FDA approved to retreat patients with Multiple Myeloma or Myelodysplastic syndrome with a specific change in their DNA. Loss of a specific part of DNA is also seen in some patients with AML.
This is a phase 1/2, dose-escalation trial of Lenalidomide given in combination with idarubicin + cytarabine. During phase 1, we will enroll patients with AML involving del 5q31; 2) patients with MDS RAEB-2 associated with monosomy 5 or segmental deletion involving 5q31, either alone or with additional cytogenetic abnormalities, and 3) older patients with any type of karyotypic profile in whom an effective and reliable standard of care remains to be developed. All 3 groups of patients define a population of patients with very poor prognoses. Dose escalation of lenalidomide will use a standard 3x3 design. Dose escalation of Lenalidomide only will take place, while the doses of idarubicin and cytarabine will be constant. This trial will have an induction component, consolidation component, and maintenance component. Overall safety and MTD will be determined from the induction phase only.
During phase 2, we will enroll only patients with AML age ≥ 60 years. During phase 2, the efficacy of this combination of Lenalidomide + idarubicin + cytarabine, at the maximum tolerated dose (MTD) for Lenalidomide (determined during phase 1), will be tested.

- •Females of childbearing potential (FCBP)† must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10 - 14 days prior to and again within 24 hours of starting lenalidomide. For FCBP who have a medical need to proceed with therapy immediately, the pregnancy test that would normally be done 10-14 days prior to initiation of lenalidomide may be done as late as 7 days prior to initiation of lenalidomide. Both this test and the pregnancy testing done within 24 hours prior to initiation of lenalidomide must be negative. FCBP must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex* condom during sexual contact with a FCBP even if they have had a successful vasectomy. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. *For patients who have latex allergies or whose partner(s) have latex allergies, alternatives will be discussed.

- •All study patients must be registered into the mandatory RevAssist® program and be willing and able to comply with the requirements of RevAssist®.
- •Females of childbearing potential (FCBP)† must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10 - 14 days and again within 24 hours prior to prescribing lenalidomide for Cycle 1 (prescriptions must be filled within 7 days as required by RevAssist) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy. See Appendix: Risks of Fetal Exposure, Pregnancy Testing Guidelines and Acceptable Birth Control Methods.

结局指标
主要结局
Phase I: Recommended Phase II Dose
时间窗: 18 months
For the Phase I component, no formal statistical analysis was planned. The primary endpoint is to determine the maximum tolerated dose (MTD) and recommended Phase II dose of lenalidomide given in combination with standard idarubicin + cytarabine induction therapy.
Phase II: Complete Response Rate of Participants Treated at Maximum Tolerated Dose (MTD)
时间窗: 24 months
Percentage of participants achieving CR/CRi. Complete Response (CR) plus Complete Response with Incomplete Count Recovery (CRi) rates. Response rates (CR + CRi) of lenalidomide following idarubicin and cytarabine induction therapy in older patients with previously untreated AML. A CR designation requires that the patient achieve the morphologic leukemia-free state and have an absolute neutrophil count of more than 1,000/μL and platelets of 100,000/μL. CRi: After chemotherapy, patients fulfill all of the criteria for CR except for residual neutropenia (1,000/μL) or thrombocytopenia (100,000/μL).
次要结局
