Brief summary: Antiemetic therapies have improved in recent years, but chemotherapy-induced nausea and vomiting (CINV) are still common and are among the most distressing side effects of chemotherapy. Aprepitant is commercially available in Canada as capsules. An oral liquid aprepitant formulation would be ideal for oral administration to patients unable to swallow capsules.


Eligibility criteria: Inclusion Criteria:

* 18 to 55 years of age
* BMI within 18.5 to 30 kg/m2
* Non-smoker
* Systolic blood pressure between 90-140 mmHg, diastolic blood pressure between 60-90 mmHg, and heart rate between 60-100 bpm, inclusive.
* Female subjects of childbearing potential should be either sexually inactive (abstinent) or be using one of acceptable methods of birth control for 15 days prior to the first dose of the study, throughout the study and for at least 30 days after the last aprepitant dose.
* Able to swallow whole aprepitant capsules
* Willingness to adhere to the protocol requirements as evidenced by the informed consent form (ICF) duly read, signed and dated by the volunteer.

Exclusion Criteria:

* Clinically significant illness or surgery within 8 weeks prior to dosing.
* Positive for hepatitis B, hepatitis C, or HIV at screening as per medical history.
* History of allergic reactions to the study drug and/or its excipients.
* Subjects concurrently treated with drugs that are metabolized through CYP3A4, including but not limited to pimozide, terfenadine, astemizole, or cisapride, ketoconazole, itraconazole, clarithromycin, diltiazem, warfarin, rifampin, carbamazepine, and phenytoin etc.
* History of drug or alcohol abuse within the last 6 months.
* Severe mental disorders.
* Blood donation of 50 mL to 499 mL of whole blood within 30 days, or more than 499 mL of whole blood within 56 days prior to drug administration.
* Pregnant or breastfeeding.
* Use of recreational drugs, prescription medications (other than hormonal contraceptive agents),non-prescription medications (over-the-counter) or natural health products within 7 days or 5 half-lives (whichever is longer) prior to the administration of the first dose of study medication.
* Consumed grapefruit or grapefruit products within 7 days of each study period
