Experimental: Eltrombopag
Single arm study. Dose Escalation.
|
Drug: Eltrombopag
Oral eltrombopag 150mg/day by mouth starting on Day 1 with dose modification over 12 weeks to a maximum of 300mg/day determined by platelet count |
- Proportion of Participants With Platelet Response [ Time Frame: up to 12 weeks ]Defined as a stable platelet count of 50,000/μl or more during any 4 week period within the possible 12 weeks while on study,and including maximal platelet counts achieved in patients with moderate to very severe aplastic anemia.
- Platelet Count Twice Baseline. [ Time Frame: Between weeks 1-12. ]Proportion of subjects who achieve platelet counts at least twice their baseline value at any point while on study medication, in patients with moderate to very severe aplastic anemia.
- Hematology Labs [ Time Frame: 12 weeks ]Association between eltrombopag use and response in hemoglobin, hematocrit, total white blood cell count, and absolute neutrophil count to be evaluate by maximal hemoglobin, hematocrit, total white blood cell count, and absolute neutrophil counts achieved in patients with moderate to very severe aplastic anemia
- Number of Patients With AE to Measure Toxicity, Using NCI CTCAE [ Time Frame: 12 weeks ]Evaluated weekly, up to 12 weeks. Association between eltrombopag use, dose, and tolerability in patients with moderate to very severe aplastic anemia
- Characterization of the PK Profile of Eltrombopag in Patients With Moderate to Very Severe Aplastic Anemia. Evaluated With AUC, Cmax, Cmin, Tmax. [ Time Frame: Weeks 2, 6 and 12 ]Samples will for PK analysis will collected as a trough level weeks 2, 6 and 12, prior to dose of eltrombopag. Additional PK level drawn at 2, 4 and 6 hours post-dose at the scheduled week 2 visit.
