Bioavailability and Bioequivalence of Two Risdiplam Tablets in Healthy Participants
Risdiplam - A Phase I, Open-Label, Multi-Period Crossover Study to Investigate the Safety, Food Effect, Bioavailability and Bioequivalence of Oral Doses of Two Different Formulations in Healthy Subjects

Intervention / Treatment
Detailed Description
Part 1 of the study is an exploratory comparison of the relative oral bioavailability of the two dispersible tablets versus risdiplam powder for oral solution as the reference. The effect of food on the bioavailability of the two dispersible tablets will be assessed by comparing fed and fasted states in a five-way crossover manner. It will also be assessed whether antacids (omeprazole) have an impact on the bioavailability of the dispersible tablets in a two-way crossover manner. The food effect on the risdiplam oral solution will also be assessed by comparing fed and fasted states in a two-way crossover manner.
In Part 2, based on the data obtained in Part 1 and provided data support further evaluation, a bioequivalence assessment and a food-effect evaluation will be conducted in two groups with the selected dispersible tablet formulation. Each group will randomly receive, in a four-way crossover, a single dose of risdiplam oral solution 5 mg in both fed and fasted states, and a single dose of the selected dispersible tablet in both fed and fasted states.
In Part 3, provided Part 1 data support further evaluation of the second formulation, the second formulation may be assessed for bioequivalence in the same way as described in Part 2.
Enrollment of the same participant in more than one cohort or group will not be permitted regardless of the study part.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: Part 1
Cohort A+B: participants will receive, in a five-period crossover way, a single oral dose of risdiplam oral solution 5 mg in fasted state and thereafter risdiplam/F21 or F22 dispersible tablet 5 mg as tablet in fasted and fed states; tablet dispersed in water in fasted and fed states, with a 14-day wash-out period in between the single-dose administrations. Cohort C+D: participants will receive, in a two-period fixed sequence design, a single dose of risdiplam/F21 or F22 dispersible tablet 5 mg in fasted state and omeprazole 40 mg once daily for 7 days + a single dose of risdiplam/F21 or F22 dispersible tablet 5 mg in fasted state, on the 7th day of omeprazole. There will be a 14-day wash-out between the two treatment periods. Cohort E: participants will receive, in a two-period crossover design, a single oral dose of risdiplam oral solution 5 mg in fasted and fed states, with a 14-day wash-out period in between the single-dose administrations. |
