Clinical Trial Summary

This is an open-label, single-dose, randomized, three-period, two-treatment, threesequence, crossover, PK, partial replicate, and comparative bioavailability study. This study may be conducted in groups. The same protocol requirements and procedures will be followed for each group.

Description:

This study will allow for the determination of the PK and intra-subject variability of rupatadine and metabolites. In addition, this study will compare the bioavailability of the rupatadine formulation (Drug Product 1) to a FDA-approved reference product (Clarinex®) (Drug Product 2) as far as the rupatadine metabolite desloratadine, and the derived compounds, is concerned.

Comparative bioavailability between Drug Product 1 and Drug Product 2 will be determined by a statistical comparison of the AUCt, AUCinf, and Cmax parameters for desloratadine (UR-12790), 3-OH desloratadine (UR-12788), 5-OH desloratadine (UR-12767), 6-OH desloratadine (UR-12766), and 3-OH-glucuronide-desloratadine (UR-12335).
