Brief Summary:
The goal of this clinical research study is to learn if eltrombopag can help to increase the number of platelets in patients with CLL. The safety of this drug will also be studied.

Condition or disease Intervention/treatment Phase
CLL Leukemia Drug: Eltrombopag Phase 2

  Show Detailed Description

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 36 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Trial of Eltrombopag for Patients With Chronic Lymphocytic Leukemia (CLL) and Thrombocytopenia
Actual Study Start Date : November 2010
Estimated Primary Completion Date : November 2019
Estimated Study Completion Date : November 2019

Arm Intervention/treatment
Experimental: Eltrombopag
Starting dose 75 mg by mouth (PO) daily for 28 day cycle.
Drug: Eltrombopag
Starting dose 75 mg by mouth (PO) daily for 28 day cycle
Other Name: Promacta

Primary Outcome Measures :
  1. Number of Participants with Overall Response [ Time Frame: 3 Months ]
    Overall response rate (OR), which is defined as the composite of complete response (CR) and major response (MR). CR is defined as an increase in platelets (PLT) count to ≥100K/µL for at least 4 weeks. MR is defined as an increase in PLT count from <20K/µL to ≥20K/µL and by at least 100% for at least 8 weeks; or for participants starting with >20K/µL platelets, absolute increase in PLT count of ≥30K/µL for at least 4 weeks: or PLT transfusion independence (no PLT transfusion) for at least 4 weeks. Overall response is best response achieved over first 3 months of treatment.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Diagnosis of chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL)
  2. Age >/= 18 years
  3. PLT transfusion-dependent, defined as need for transfusion to maintain PLT count >/=20K/µL, or the average of two (non-transfused) PLT counts taken within 2 weeks of the screening period </=50K/µL, with no individual count >55K/µL
  4. Patients with ITP must have failed at least 1 prior treatment for ITP including one of the following: corticosteroids, rituximab, splenectomy, cyclosporine
  5. At least 3 weeks must have elapsed since the last chemotherapy treatment for CLL
  6. ECOG performance status (PS) </=2
  7. Adequate liver function (total bilirubin </=2* upper limit normal (ULN); ALT </=2.5* ULN)
  8. Adequate renal function (serum creatinine Cr </=2.2 mg/dL)
  9. For patients with ITP on corticosteroids or cyclosporine, dose of corticosteroids or cyclosporine must be stable for 2 weeks prior to enrollment and planned to be tapered in patients responding to eltrombopag
  10. Able to provide informed consent

Exclusion Criteria:

  1. Concurrent chemotherapy for CLL
  2. Diagnosis of Richter's transformation
  3. Uncontrolled autoimmune hemolytic anemia i.e. patients with AIHA that is not controlled with treatment such as corticosteroids or cyclosporine. This would include patients who require PBRC transfusions or who do not have a stable hemoglobin (HGB) due to ongoing hemolysis.
  4. Concurrent treatment for ITP (except for corticosteroids and cyclosporine)
  5. Diagnosis of myelodysplastic syndrome or acute myeloid leukemia
  6. Active infection or significant medical illness as determined by the treating physician
  7. Treatment with thrombomimetic agents in the past 3 months (rTPO, PEG-rHuMGDF, Nplate or Promacta)
  8. Pregnant or breast feeding subjects and subjects not willing to use adequate contraceptive precautions
