|Official Title:||Safety of Romiplostim (Nplate®) in Patients Who Have Failed to Achieve Platelet Engraftment Following Umbilical Cord Blood Transplant|
|Actual Study Start Date :||April 10, 2015|

Experimental: Romiplostim treatment
Romiplostim at the assigned dose will be administered subcutaneously (SQ) once a week for 6 weeks (i.e. 6 doses) unless platelet count exceeds 100 x 10^9/L and at least 4 doses of therapy were given.After the initial dose, subsequent doses will be administered within a window of +/- 3 days.
Romiplostim at the assigned dose will be administered subcutaneously (SQ) once a week for 6 weeks. The dose will be assigned at the time of subject registration. This is a dose escalation to determine the maximum tolerated dose. The doses include 4 mcg/kg/dose, 6 mcg/kg/dose, 8 mcg/kg/dose, and 10 mcg/kg/dose.
Other Name: Nplate
- Maximum tolerated dose of romiplostim [ Time Frame: Day +28 blood transplant (UCBT) ]Measured by number of patients who have failed to achieve platelet engraftment by day +28 after a myeloablative or nonmyeloablative umbilical cord blood transplant (UCBT)
- Platelet recovery [ Time Frame: Day +28 ]Average speed of platelet recovery in patients who have failed to achieve platelet engraftment.
- Thrombocytopenia [ Time Frame: Day +28 ]Incidence of clinically significant bleeding episodes and number of platelet transfusions.
- Bone marrow fibrosis [ Time Frame: Day 100 post transplant ]Incidence of bone marrow fibrosis.
