Brief Summary

This phase II trial studies how well lenalidomide (LEN) and eltrombopag olamine (ELT) work in treating patients with symptomatic anemia in low or intermediate myelodysplastic syndrome (MDS). Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Eltrombopag olamine may increase the number of white blood cells and platelets found in bone marrow or peripheral blood. Giving lenalidomide and eltrombopag olamine may be an effective treatment for myelodysplastic syndrome.

Detailed Description

PRIMARY OBJECTIVES (not Outcome Measures):

I. To evaluate the rate of hematologic improvement of the eltrombopag (eltrombopag olamine)/lenalidomide combination (as per Modified International Working Group [IWG] criteria).

II. To evaluate the safety and tolerability of the combination.

SECONDARY OBJECTIVES (not Outcome Measures):

I. To compare the time to hematologic improvement. II. To evaluate the duration of hematologic improvement III. To evaluate the effect of combination treatment on platelet counts, platelet transfusions and bleeding events.

IV. To evaluate the frequency of bone marrow response (complete response [CR] + partial response [PR]) and cytogenetic response.

V. To evaluate the relationship between mutations in bone marrow stem cells and response.

VI. To evaluate the relationship between various stem and progenitor alterations and response.

OUTLINE: Patients are initially assigned to 1 of 2 treatment arms.

ARM A: Patients with platelet counts >= 50,000 receive lenalidomide orally (PO) daily or every other day (QOD) on days 1-21. If platelet counts fall below 50,000, patients discontinue lenalidomide and receive eltrombopag olamine PO daily or QOD until platelet count is maintained above 50,000 for 2 weeks. Patients then resume lenalidomide PO daily or QOD. If platelets fall below 50,000 again, patients receive eltrombopag olamine as before. When platelet counts are maintained above 50,000 for 2 weeks, patients resume lenalidomide concurrently with eltrombopag for all subsequent courses.

ARM B: Patients with platelet counts < 50,000 receive eltrombopag olamine PO daily or QOD on days 1-28 until platelet counts is maintained above 50,000 for 2 weeks. Patients then receive treatment as in Arm A.

In both arms, treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then every 12 months for 5 years.

Eligible patients with a diagnosis of MDS or non-proliferative chronic myelomonocytic leukemia (CMML) (WBC ≤ 12,000/mL) of at least 3-month duration according to WHO criteria and International Prognostic Scoring System categories of low or intermediate-1-risk disease. Patients either had symptomatic anemia untransfused with hemoglobin ≤ 10 g/dL in the 8 weeks before starting the study or had RBC transfusion dependence (i.e., ≥ 2 units/mo) confirmed 8 weeks before starting the study and/or PLTs <50,000 k/uL with hemoglobin >10.0 g/dL. Patients must not have received prior therapy with LEN (for > 2 months) nor ELT

Study Groups

Arm A (lenalidomide, eltrombopag olamine)

Patients with baseline platelet counts >= 50,000 receive lenalidomide PO daily or QOD on days 1-21. If platelet counts fall below 50,000, patients discontinue lenalidomide and receive eltrombopag olamine PO daily or QOD until platelet count is maintained above 50,000 for 2 weeks. Patients then resume lenalidomide PO daily or QOD. If platelets fall below 50,000 again, patients receive eltrombopag olamine as before. When platelet counts are maintained above 50,000 for 2 weeks, patients resume lenalidomide concurrently with eltrombopag for all subsequent courses.

Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

Inclusion Criteria

• Patient must have a documented diagnosis of myelodysplastic syndrome (MDS) of at least three months duration (MDS duration >= 3 months) according to World Health Organization (WHO) criteria or non-proliferative chronic myelomonocytic leukemia (CMML) (white blood cells [WBC] =< 12,000/L)
• Patients must have International Prognostic Scoring System (IPSS) categories of low- or intermediate-1-risk disease
• Patients must have symptomatic anemia untransfused with hemoglobin =< 9.5 g/dL within 8 weeks of registration or with red blood cell (RBC) transfusion-dependence (i.e., >= 2 units/month) confirmed for a minimum of 8 weeks before randomization
• Patients must have IPSS score determined by cytogenetic analysis prior to randomization; patients with cytogenetic failure and =< 10% marrow blasts will be eligible
• Patients must be off all disease modifying therapy for MDS for 28 days prior to initiation of study treatment; patients may receive hydrocortisone prophylactically to prevent transfusion reactions
• Patients must not have documented iron deficiency; all patients must have documented marrow iron stores; if marrow iron stain is not available, the transferrin saturation must be >= 20% or a serum ferritin >= 100 ng/100 mL or soluble transferring receptor < 5 mg/L.
• Women must not be pregnant or breastfeeding; females of childbearing potential should have 2 negative pregnancy tests (sensitivity of at least 50 mIU/mL); the first test should be performed within 10-14 days, and the second test within 24 hours prior to prescribing lenalidomide
