About

Lenalidomide has shown significant efficacy in the treatment of anemia associated with both 5q- and non 5q- MDS patients. The mechanism(s) of action of lenalidomide in MDS is still to be determined, but given the differences in response rates seen, it is probable that the mechanism is different for patients with 5q- disease compared to non 5q- patients. T-cell mediated activation of intramedullary apoptosis in patients with early MDS leading to impaired hematopoiesis has been well described. Immunomodulation with agents such as ATG, cyclosporine and thalidomide have demonstrated clear activity in some patients with MDS. Lenalidomide, among its many effects, is a potent immunomodulator, which may contribute to its ability to improve red blood cell counts in patients with MDS. It is possible that this effect could be augmented with the addition of cyclosporine A (CSA), in a similar manner to CSA effects in patients with other bone marrow failure syndromes such as aplastic anemia.

Subjects will be treated with lenalidomide 10 mg PO daily days 1-28 of a 28-day cycle. Cyclosporine A will be started on day 1 of cycle 2 (day 29) at a dose of 5 mg/kg per day given orally in 2 divided doses. Cyclosporine A levels will be assessed weekly and doses will be adjusted to maintain a serum trough level between 100-450 mg/ml. Patients will continue on therapy for minimum of 16 weeks unless toxicity occurs which precludes continuation on therapy, disease progression and/or patient withdrawal of consent. Patients not achieving response after completing 16 weeks of therapy will discontinue treatment. Patients achieving response will continue therapy until disease progression, unacceptable toxicity or loss of response.

Age ≥ 18 years at the time of signing the informed consent form.
Able to adhere to the study visit schedule and other protocol requirements.
Diagnosis of low or intermediate-1 risk IPSS (MDS without an abnormality of chromosome 5 involving a deletion between bands q31 and q33. Red blood cell (RBC) transfusion-dependent anemia as having received ≥ 2 units of RBCs within 8 weeks on the first day of study treatment.
ECOG performance status of ≤ 2 at study entry
Laboratory test results within the following ranges:
- Absolute neutrophil count (ANC) >500 x 109/L
- Platelet count ≥ 50 x 109/L
- Serum creatinine ≤ 2.0 mg/dL
- Total bilirubin ≤ 1.5 mg/dL
- AST (SGOT) and ALT (SGPT) ≤ 2 x ULN
Disease free of prior malignancies for ≥ 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "insitu" of the cervix or breast.
All study participants 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 prior to and again within 24 hours of prescribing lenalidomide (prescriptions must be filled within 7 days) 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 also agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy.
Able to take asprin (81 or 325 mg) daily as a prophylactic anticoagulation (patients intolerant to ASA may use warfarin or low molecular weight heparin).

Exclusion criteria

Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.
Pregnant or breast feeding females. (Lactating females must agree not to breast feed while taking lenalidomide).
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.
Use of any other experimental drug or therapy within 28 days of baseline.
Known hypersensitivity to thalidomide. Prior ≥ grade 3 NCI CTCAE (Version 3.0) allergic reaction/hypersensitivity.
The development of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs.
Any prior use of lenalidomide.
