Brief summary:
This 5-part study will evaluate the safety, tolerability, and pharmacokinetics of two formulations of MK-0517 (with and without polysorbate 80) and aprepitant in healthy adults. Parts I to IV of this study will examine different doses of MK-0517 as well as two different formulations of MK-0517 (with and without polysorbate 80). Part V of the study will compare single doses of intravenous non-PS80 MK-0517 to oral 125-mg capsule of aprepitant. The primary hypothesis for Part V of the study is that a single intravenous dose of 100-mg or 115-mg MK-0517 is area under the plasma-time curve (AUC) equivalent to that of the 125-mg oral aprepitant capsule in young healthy participants.
