This phase II, double-blind, placebo-controlled, two-treatment four periods cross-over trial investigated the clinical safety, tolerability and the efficacy of R093877 (prucalopride) in improving the symptoms associated with chronic intestinal pseudo-obstruction (CIP) in subjects with CIP.~Subjects were treated for 4 periods of 12 weeks each with either R093877 2 mg (2 periods) or placebo (2 periods). In each of the first and second 6 month period, there was a placebo (PLA) and an active drug (PRU) treatment period. There were no wash-out periods. In total,7 subjects were randomized; 2 were assigned to the PLA-PRU-PLA-PRU, 2 to the PRUPLA-PRU-PLA, 2 to the PLA-PRU-PRU-PLA, and 1 to the PRU-PLA-PLA-PRU sequence group. Subjects were allowed to use up to 4 mg of prucalopride per day if the 2 mg dose seemed to be insufficient. Two subjects used an average of 3 mg of prucalopride per day during the active drug periods.
This study was designed to investigate the clinical safety, tolerability and efficacy of prucalopride in improving the symptoms associated with chronic intestinal pseudo-obstruction (CIP) in subjects with CIP. The study hypothesis was that prucalopride at doses up to 4 mg is safe, well tolerated, efficacious and improves the symptoms associated with CIP.
