Further study details as provided by Sanofi:

Primary Outcome Measures:
  • Changes of microbial composition of fecal bacterial flora by PCR-DGGE analysis. [ Time Frame: between samples obtained at baseline and follow-up ]

Secondary Outcome Measures:
  • Changes from baseline of body weight [ Time Frame: During the total study period ]
  • Assessment of abdominal symptoms [ Time Frame: Daily ]
  • Presence of Bacillus clausii spores in feces [ Time Frame: after heat shock treatment on selective medium. ]
  • Number and rate of patients with GI symptoms and time to first development of symptoms. [ Time Frame: recorded in a daily diary card for the total study period ]

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects with persistency of symptoms and requiring antibiotics for bacterial upper respiratory tract infections, i.e. complicated acute otitis media (diagnosed by otoscopic examination) or beta-haemolytic streptococcal pharyngo-tonsillitis (diagnosed by pharyngeal swab and rapid antigen detection test or positive culture);
  • Outpatients or patients attending an emergency room for both diagnoses, and inpatients in case of complicated acute otitis media;
  • Written informed consent from both parents.

Exclusion Criteria:

  • History of clinically significant chronic diseases, or chronic diseases necessitating the use of continuous drug therapies, or of any disease that may interfere with the successful completion or the objectives of the trial;
  • Clinical evidence of relevant cardiovascular, respiratory, renal, hepatic, gastrointestinal, hematological, neurological or of any disease that may interfere with the successful completion or the objectives of the trial;
  • Use of antibiotics, prebiotics or probiotics (medications or dietetic supplements) in the last 2 weeks prior to study entry;
  • Hypersensitivity to the investigational product;
  • Subjects enrolled in another trial in the previous three months.
