Food Effect and Bioavailability of Deflazacort Formulations in Healthy Volunteers

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

This is a Phase 1, single-center, single-dose, randomized, 5-period crossover study designed to assess the comparative bioavailability and food effect of deflazacort. A total of 45 subjects will be randomly assigned to receive 1 of 5 treatment sequences. Each dosing sequence will be enrolled in parallel and all subjects will receive all 5 treatments in a crossover fashion.
