A Phase 4 interventional study of Smecta and Smecta placebo in Acute Diarrhoea, sponsored by Ipsen. Completed at 71 sites in 6 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-11-05.
Sponsored by Ipsen · Phase 4, Interventional, and Treatment
The purpose of the study is to demonstrate that diosmectite efficacy is superior to placebo regarding time to recovery of an acute diarrhoea episode presumed of infectious origin in adult subjects.

Time to Recovery
Time to recovery was defined as the time from the first study treatment intake recorded in the electronic case report form (eCRF) to the first formed stool followed by a non-watery stool, recorded in the DEB. Results are presented as median time to recovery, calculated using the Kaplan-Meier technique. Participants prematurely withdrawn without recovery or ending the study without recovery were censored (not responders) at the date/time of their last stool as recorded in the DEB. Participants who had not filled in the DEB (i.e. no post-baseline evaluation of stools) were censored at the date/time of their first study treatment intake (or the randomisation date/time if not administered).
Time frame: From randomisation (Day 1) up to Day 9
Time From Diarrhoea Onset to Recovery
The event of diarrhoea onset (i.e. loose or watery stool) was recorded in the eCRF and the event of recovery (i.e. first formed stool followed by a non-watery stool) was recorded in the DEB. Results are presented as median time from diarrhoea onset to recovery, calculated using the Kaplan-Meier technique. Participants prematurely withdrawn without recovery or ending the study without recovery were censored (not responders) at the date/time of their last stool as recorded in the DEB. Participants who had not filled in the DEB (i.e. no post-baseline evaluation of stools) were censored at the date/time of their first study treatment intake (or the randomisation date/time if not administered).
Time frame: From randomisation (Day 1) up to Day 9
Time From Diarrhoea Onset to First Formed Stool
The event of diarrhoea onset (i.e. loose or watery stool) was recorded in the eCRF and the event of first formed stool was recorded in the DEB. Results are presented as median time from diarrhoea onset to first formed stool, calculated using the Kaplan-Meier technique. Participants prematurely withdrawn with no formed stool or ending the study with no formed stool were censored at the date/time of their last stool as recorded in the DEB. Participants who had not filled in the DEB (i.e. no post-baseline evaluation of stools) were censored at the date/time of their first study treatment intake (or the randomisation date/time if not administered).
Time frame: From randomisation (Day 1) up to Day 9
Time From the First Study Treatment Intake to the Last Watery Stool
The event of first study treatment intake was recorded in the eCRF and the event of last watery stool was recorded in the DEB. Results are presented as median time from first study treatment intake to last watery stool, calculated using the Kaplan-Meier technique. Participants prematurely withdrawn with no watery stool or ending the study with no watery stool were censored at the date/time of their last stool as recorded in the DEB. Participants who had not filled in the DEB (i.e. no post-baseline evaluation of stools) were censored at the date/time of their first study treatment intake (or the randomisation date/time if not administered).
Time frame: From randomisation (Day 1) up to Day 9
Number of Stools, Per 12-Hour Period
Number of stools, per 12-hour period, was recorded in the DEB.
Time frame: From randomisation (Day 1) up to Day 9
Number of Watery Stools, Per 12-Hour Period
Number of watery stools, per 12-hour period, was recorded in the DEB.
Time frame: From randomisation (Day 1) up to Day 9
Percentage of Participants With Associated Symptoms, Per 12-Hour Period
Percentage of participants with associated symptoms (at least 1 symptom of nausea, vomiting, abdominal pain or anal irritation) per 12-hour period is presented. Nausea, vomiting, abdominal pain and anal irritation were recorded in the DEB.
Time frame: From randomisation (Day 1) up to Day 9
Abdominal Pain Intensity Scores, Per 12-Hour Period
Abdominal pain intensity per 12-hour period was recorded in the DEB. Abdominal pain intensity was rated with a 5-point ordinal scale: 0 = absent, 1= mild, 2 =moderate, 3 = severe, 4= very severe. Higher scores indicate a worse outcome. The median abdominal pain intensity score for each 12-hour period is presented.
Time frame: From randomisation (Day 1) up to Day 9
The study enrolled adult participants with a recent episode of acute diarrhoea presumed of infectious origin, defined as the passage of 3 or more unformed (loose or watery) stools per day without alarm symptoms within the first 48 hours. Participants were randomised at 62 study centres in Algeria, Czech Republic, Egypt, Lebanon, Poland and Tunisia.
