Brief Summary:
The purpose of this study is to evaluate the efficacy of prucalopride 2 mg, given orally once daily for 12 weeks, in combination with PEG or lactulose, in treatment of women with Chronic Constipation (CC) in whom laxatives fail to provide adequate relief, as measured by the percentage of subjects with a weekly average increase of 1 or more spontaneous complete bowel movements (SCBMs) (responders) during the 12-week treatment phase as compared to the baseline.

Condition or disease Intervention/treatment Phase
Constipation Drug: Prucalopride Drug: Polyethylene glycol (PEG) Drug: Lactulose Phase 4

Detailed Description:

This is a multicenter, open-labeled, single-arm, interventional study to evaluate the efficacy and safety of prucalopride in real clinical practice.

It consists of 2 phases: a 1-week run-in phase, a 12 week, open-label treatment phase. Study population is women with CC who have been treated with laxatives but failed to obtain adequate relief within the preceding 6 months. Patients who meet the inclusive and without exclusive criteria will be enrolled in the study and signed an Informed Consent Form. They are instructed not to change their diet, lifestyle during the study.

At the first week of the study, subjects will continue PEG or lactulose treatment, and they will not be allowed to use any other laxatives and drugs for CC. Subjects will be required to maintain a written stool diary as well as the use of PEG and lactulose. Any drug affecting the colonic motility will be prohibited during the study. Following this run-in phase, subjects enter the 12-week open-label treatment phase. During the treatment phase, subjects will be treated for 12 weeks with prucalopride 2 mg, given orally once daily with or without breakfast in the morning. Subjects will be required to continue PEG or lactulose treatment with the same dosage as that in the run-in period. If necessary, due to intolerable side effects (ie, severe diarrhea,), dosage decrements of PEG or lactulose treatment may be made at any time or the subject could discontinue the PEG or lactulose treatment, based on investigator's judgement. Subjects will record study drug and laxative medication dosing information and information related to BMs in a daily diary throughout the study. PAC-SYM and PAC QOL questionnaires will be completed at Weeks 0, 4, 12. Subject safety will be monitored throughout the study.

Arm Intervention/treatment
Experimental: Prucalopride plus Polyethylene glycol or lactulose Drug: Prucalopride
During the 12-week treatment phase of the study, the daily dose of 1 tablet of 2-mg prucalopride will be administrated orally before breakfast.

Drug: Polyethylene glycol (PEG)
Optimized dose of PEG will be administrated for 13 weeks (1 week run-in+12 weeks intervention).

Drug: Lactulose
Optimized dose of Lactulose will be administrated for 13 weeks (1 week run-in+12 weeks intervention).




Primary Outcome Measures :
  1. Percentage of subjects with a weekly average increase of 1 or more Spontaneous Complete Bowel Movement (SCBM) during the 12-week treatment phase as compared to the baseline [ Time Frame: 12 weeks ]

Secondary Outcome Measures :
  1. Percentage of subjects with a weekly 3 or more Spontaneous Complete Bowel Movement (SCBM) during the 12-week treatment phase as compared to the baseline [ Time Frame: 12 weeks ]
  2. Percentage of subjects with a weekly average increase of 1 or more Spontaneous Complete Bowel Movement (SCBM) during the first 4 weeks treatment phase as compared to the baseline [ Time Frame: 4 weeks ]
  3. Percentage of subjects with a weekly average increase of 1 or more Spontaneous Bowel Movement (SBM), Bowel Movement (BM) during the 12-week treatment phase as compared to the baseline [ Time Frame: 12 weeks ]
  4. Average number of Spontaneous Complete Bowel Movement (SCBM) per week [ Time Frame: 12 weeks ]
  5. Average number of SBMs per week [ Time Frame: 12 weeks ]
  6. Average number of all BMs per week [ Time Frame: 12 weeks ]
  7. Percentage of BMs with normal consistency (Types 3-4 based on Bristol Stool Scale) per week [ Time Frame: 12 weeks ]
  8. Average weekly change of PEG or lactulose frequency and dosage as compared to baseline during the 12-week treatment phase [ Time Frame: 12 weeks ]
  9. Improvement of constipation symptoms and higher satisfaction as measured by subject's global assessments and PAC-SYM scores. Improvement is defined as that the mean score reduction from baseline is ≥0.2 [ Time Frame: Baseline, 12 weeks ]
  10. Improvement in physical, psychological, and emotional stress as measured by PAC QOL scores. Improvement is defined as that the mean score reduction from baseline is ≥0.3 [ Time Frame: Baseline, 12 weeks ]
