Clinical Trial Summary

This is a 2-arm, parallel-group active- and placebo-controlled, double-blind randomised study, stratified by gender and with a hybrid crossover group design, to compare treatment with prucalopride 2 mg/day (intended therapeutic dose) and prucalopride 10 mg/day (supratherapeutic dose) with placebo. A single oral dose of 400 mg moxifloxacin is included as a positive control in terms of the effect on cardiac repolarisation.

Study hypothesis:

Treatment with therapeutic (2 mg) or supratherapeutic (10 mg) doses of prucalopride in healthy male and female volunteers will not increase QTc interval compared to placebo.

Description:

A total number of 120 healthy subjects (with an approximate 1:1 female:male ratio) are planned to be randomised.

Day 1: a baseline ECG profile. Day 1: Group 1 will receive prucalopride, Group 2a will receive moxifloxacin, and Group 2b will receive placebo.

On Day 5 (steady-state level is reached), a full ECG assessment day will be performed, enabling the comparison of prucalopride 2 mg with placebo.

Subsequently, the number of tablets will be escalated in all groups (blinded) with 1 tablet a day up to 5 tablets.

On Day 13 (steady state for the supratherapeutic dose level of 10 mg of prucalopride) another ECG assessment day will be performed, enabling a comparison of prucalopride 10 mg with placebo.

Group 2b will receive a single dose of moxifloxacin on Day 15. All subjects will be discharged on Day 16. Subjects will remain in the CRU throughout the treatment period.

All subjects will return for a follow-up visit on Day 30 (± 1 week) (approximately 14 days after the last dose).
