    Abstract:
    BACKGROUND: Prucalopride is a high-affinity 5-HT4 receptor agonist for the treatment of chronic constipation. The aims of this study were to investigate the relationship between health-related quality of life (HRQoL) and symptoms of constipation, and to assess the response of HRQoL to treatment using integrated data from three phase III trials of prucalopride. METHODS: This was an integrated analysis of data from three pivotal multicenter, double-blind, randomized, placebo-controlled, parallel-group trials (ClinicalTrials.gov Identifiers: NCT00488137, NCT00483886 and NCT00485940). Relationships were investigated between Patient Assessment of Constipation Quality of Life (PAC-QOL) scores, Patient Assessment of Constipation Symptoms (PAC-SYM) scores, bowel movement frequency (assessed using daily diaries), and treatment. KEY RESULTS: Patients treated with prucalopride 2 mg (n = 659) and placebo (n = 661) were included in the analysis. An improvement in PAC-SYM scores correlated well with an improvement in PAC-QOL overall score (r = 0.711) and satisfaction subscale score (r = 0.589). After 12 weeks, PAC-QOL overall score and satisfaction subscale score significantly (p < 0.001) improved by ≥ 1 point (clinically relevant) in 36.5% and 44.1% of patients treated with prucalopride, compared with 18.5% and 22.4% with placebo respectively. Moreover, 39.0% of patients with an improvement in satisfaction of ≥ 1 point achieved ≥ 3 spontaneous complete bowel movements/week, compared with 7.4% of those with no improvement in satisfaction (<1 point). CONCLUSIONS & INFERENCES: Improvements in PAC-QOL overall score and satisfaction score were associated with improvements in symptoms of chronic constipation. Compared with placebo, treatment with prucalopride significantly improved HRQoL.
