A Single Center, Open-label, Randomized, Two-period Crossover Food Effect Study of Single Doses of Tivozanib (AV-951) in Healthy Subjects

A Phase 1, Single Center, Open-label, Randomized, Two-period Crossover Food Effect Study of Single Doses of Tivozanib (AV-951) in Healthy Subjects

This study will determine the effect of food on the pharmacokinetics (PK) of a single dose of 1.5 mg tivozanib in normal healthy subjects.

This study will be an open-label, randomized, two-period, crossover PK food effect study of tivozanib administered orally at 1.5 mg. Subjects will be screened for eligibility up to 28 days prior to entry into the study.

For each of 2 study periods, subjects will be admitted to the clinical research unit (CRU) on the day before dosing and fast overnight (approximately 10 hours). On the morning of dosing for each of the 2 study periods, subjects will receive a single oral dose of 1.5 mg tivozanib in either the fasted or fed state. Subjects will remain at the CRU for at least 48 hours after administration of study drug for collection of serial blood samples for pharmacokinetic (PK) analysis and safety monitoring. Subjects will return to the CRU on an outpatient basis for collection of additional blood samples for up to 504 hours postdose.

• Male subjects who are either sterile or agree to use, during the period from informed consent until 45 days following Study Completion, 1 of the following approved methods of contraception: a double barrier method (eg, male condom with spermicide, use by female sexual partner of an intrauterine device with spermicide, a female condom with spermicide, contraceptive sponge with spermicide, a diaphragm with spermicide, or use of a cervical cap with spermicide); a sterile sexual partner; a female sexual partner using an intravaginal system (eg,NuvaRing®); or a partner using an oral, implantable, transdermal, or injectable contraceptives.
• Able to comprehend and willing to sign an informed consent form (ICF).

Exclusion Criteria:

• History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the Investigator.

• History or presence of an abnormal ECG, which, in the Investigator's opinion, is clinically significant.
• Diagnosis of alcoholism or drug addiction within 1 year prior to Period 1 Check-in.
• Participation in any other investigational drug study in which receipt of an investigational study drug occurred within 5 half-lives or 30 days, whichever is longer prior to informed consent.
• Use of any prescription medications or products within 14 days prior to Period 1 prior to informed consent.
• Use of any over-the-counter (OTC), non-prescription preparations (including vitamins, minerals, and phytotherapeutic, herbal, dietary supplements, or plant derived preparations) within 7 days prior to each study period Check-in.
• Use of alcohol-, grapefruit-, Seville orange-, or caffeine-containing foods, juices, or beverages within 72 hours prior to each study period Check-in.

• Blood pressure greater than 140/90 mmHg confirmed by repeat at Screening or at Period 1 Check-in.
• Any acute or chronic condition that, in the opinion of the Investigator, would limit the subject's ability to complete and/or participate in this clinical study.
