This was a double-blind, placebo-controlled, randomized, parallel, dose-escalation study to assess the pharmacokinetics, platelet response, safety, and tolerability of supratherapeutic doses of eltrombopag (100 mg, 150 mg, and 200 mg once daily) administered for 5 days to 33 healthy adult volunteers. Plasma eltrombopag concentrations accumulated between days 1 and 5, with average increases of 66% to 81% for area under the plasma concentration-time curve from time zero to the end of the 24-hour dosing interval (AUC(0-?)) and 32% to 45% for maximum observed plasma concentration (C(max)) across doses. After 5 days of dosing, AUC(0-?) was dose-proportional and C(max) was less than dose-proportional over eltrombopag 100 to 200 mg with slope estimates (90% confidence intervals) of 0.92 (0.45-1.39) and 0.76 (0.29-1.22), respectively. Platelet counts peaked at day 14, and maximum change from baseline platelet count increased dose-dependently, with mean platelet count increases of 14, 67, 107, and 150 Gi/L for placebo and eltrombopag 100 mg, 150 mg, and 200 mg, respectively. There was no notable difference in day 14 mean platelet aggregation between eltrombopag (59 to 74%) and placebo (67%), although this was not tested statistically. There was no notable difference in adverse event frequency across eltrombopag doses. Eltrombopag pharmacokinetics and platelet response were dose-dependent, and doses up to 200 mg/d were well tolerated, with safety profiles similar to placebo.
