Brief summary

This is an open-label, single-dose, randomized, two-period, crossover study to evaluate absolute bioavailability of Brincidofovir (BCV) after administration of either: PART A (Non-Japanese) : a single, 200 mg dose of BCV suspension formulation compared to a single, 20 mg dose of BCV IV formulation. PART B: (Japanese) a single 100 mg dose of BCV suspension formulation compared to a single 10 mg dose of BCV IV formulation. A screening evaluation will be performed no more than 28 days prior to the first BCV dose (Period 1 Day 1) to identify subjects who are eligible to participate in the study. Eligible subjects will be randomized in a 1:1 ratio. In each period, BCV will be administered on Day 1. Subjects will be admitted to the clinic on Day -1, the day prior to dosing. Subjects will remain in the clinic until the morning of Day 3. A follow visit will occur following the last visit.

Interventions

This is an open-label, single-dose, randomized, two-period, crossover study to evaluate absolute bioavailability of Brincidofovir (BCV) after administration of either: PART A (Non-Japanese) : a single, 200 mg dose of BCV suspension formulation (20 mls to be drunk) compared to a single, 20 mg dose of BCV IV formulation.

PART B: (Japanese) a single 100 mg dose of BCV suspension formulation (10 mls to be drunk) compared to a single 10 mg dose of BCV IV formulation. All doses will be administered while resident in a phase 1 unit. Volunteers will need to stay 2 nights in the unit for each dose. A wash out of at least 21 days will occur between the two treatments.
