Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients >/= 35 days post HCT with Platelet count </= 20 x 10^9/l sustained for 7 days or patients are platelet transfusion dependent, and
  2. Neutrophil count >/= 1.5 x 10^9/l anytime within the last seven days before enrollment. Patients can be on myeloid or erythroid growth factors for example filgrastim), and
  3. Age >/= 18

Exclusion Criteria:

  2. ALT >/= 2.5 times the ULN
  3. Serum bilirubin >2mg/dl (unless due to Gilbert's syndrome)
  4. Documented deep vein thrombosis within 1 year before enrollment on the study, except if upper arm thrombosis related to central venous catheters, within 3 months before enrollment on the study.
  5. ECOG Performance status >2
  6. Pregnancy: Women of child-bearing potential and men must agree to use contraception prior to study entry and for the duration of study participation. A woman of child-bearing potential is defined as a woman who has not been naturally post-menopausal for at least 12 consecutive months or with no previous surgical sterilization.
