A Phase 1, 2-Part, Single Ascending Dose Assessment of the Safety, Tolerability, and Pharmacokinetics of Rolapitant Intravenous in Healthy Volunteers

Part 1 of the study is designed to evaluate the safety and tolerability of a SAD, up to 6
cohorts,of rolapitant IV (2 mg/mL solution) administered as an IV infusion over 30 minutes.

In Part 2 of the study, the safety and tolerability of the highest safe and well-tolerated
dose established in Part 1 will be evaluated in an expanded cohort. The highest safe and
well-tolerated dose established in Part 1 will be ascertained by the following criteria: an
upper limit of 90% confidence interval (CI) for Cmax. A minimum of 40 subjects will be
enrolled in Part 2.

Main Inclusion Criteria:

birth control (excluding hormonal birth control methods) from Screening through 30
days after final study drug administration.

- Subject must have a body mass index (BMI) from 18.5 to 32.0 kg/m2 and a weight of

test drug, whichever is longer, before the time of first study dose.

- Subject must not have a history of hypersensitivity to rolapitant IV or any of its
excipients or who have completed a study visit as part of a previous rolapitant study
within the 6 months prior to first study drug administration (Day

- Subject must not have poor venous access or consider venipuncture intolerable.

- Subject must not have a history of significant complications or anxiety associated
with the IV administration of medications that, in the opinion of the Investigator,
