Interventions
Registration Number
NCT02284880
Lead Sponsor
Bial - Portela C S.A.
Brief Summary

Phase I, two-centre, open-label, randomized, gender-balanced, single-dose, laboratory blinded, two-period, two-sequence, crossover study in 2 groups of 20 healthy male and female subjects, to demonstrate the bioequivalence (BE) between two active product ingredient (API) sources of eslicarbazepine acetate (ESL)

Detailed Description

Phase I, two-centre, open-label, randomized, gender-balanced, single-dose, laboratory blinded, two-period, two-sequence, crossover study in 2 groups of 20 healthy male and female subjects. The study consisted in 2 periods separated by a wash-out of at least 7 days between doses. To demonstrate the bioequivalence (BE) between two active product ingredient (API) sources \[current API source - marketed formulation (MF) versus new API source - to-be-marketed (TBM)\] of eslicarbazepine acetate (ESL)
