入选标准
- •Patient must be able to understand and voluntarily sign an informed consent form.
- •Patient must be ≥ 18 years old.
- •Patient must be able to adhere to the study visit schedule and other protocol requirements.
- •Patient must have histologically confirmed Myelodysplastic Syndrome as defined by FAB Classification including CMML and secondary MDS which has either:
- •progressed at any time during treatment with hypomethylating agents
- •failed to achieve a response after 6 cycles
- •progressed after treatment with hypomethylating agents had been discontinued Criteria for response and for progression as defined by revised IWG criteria
- •Patient must have discontinued all previous cancer therapy, including radiation, hormonal therapy and surgery at least 4 weeks prior to treatment in this study.
- •Patient must have an ECOG performance status of ≤ 2 at study entry
- •Patient must have laboratory test results within these ranges:
- •calculated creatinine clearance ≥ 30ml/min by Cockcroft-Gault formula
- •total bilirubin ≤ 1.5 x ULN
- •AST (SGOT) and ALT (SGPT) ≤ 3 x ULN
- •Patient must be disease free of prior malignancies for at least 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix or breast.
- •Patient must be registered into the mandatory Revlimid REMS® program and be willing and able to comply with the requirements of Revlimid REMS®.
- •If a female of childbearing potential (FCBP), patient must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10 to 14 days prior to initiation of therapy and again within 24 hours prior to prescribing lenalidomide for Cycle 1 (prescriptions must be filled within 7 days).
- •Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the Revlimid REMS® program. A FCBP is defined as a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).
- •If a FCBP, patient must agree to use two reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual intercourse during the following time periods related to this study: 1) for at least 28 days before starting study drug; 2) while participating in the study; and 3) for at least 28 days after discontinuation from the study. The two methods of reliable contraception must include one highly effective method (i.e. intrauterine device (IUD), hormonal [birth control pills, injections, or implants], tubal ligation, partner's vasectomy) and one additional effective (barrier) method (i.e. latex condom, diaphragm, cervical cap). FCBP must be referred to a qualified provider of contraceptive methods if needed
排除标准
- •Patient must not have any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.
- •Patient must not be pregnant or breastfeeding.
- •Patient must not have any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.
- •Patient must not use any other experimental drug or therapy within 28 days of baseline.
- •Patient must not have a known hypersensitivity to thalidomide.
- •Patient must not have developed of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs.
- •Patient must not have any prior use of lenalidomide.
- •Patient must not be concurrently using other anti-cancer agents or treatments.
- •Patient must not have known seropositivity for or active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV). Patients who are seropositive because of hepatitis B virus vaccine are eligible.
研究组 & 干预措施
Lenalidomide
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.
干预措施: Lenalidomide (Drug)
结局指标
主要结局
Number of Participants With Confirmed Responses (Complete Remission, Partial Remission, or Hematologic Improvement) as Defined by the International Working Group Criteria
时间窗: 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
