Brief Summary

During or after antibiotic treatment, antibiotic residues impair the intestinal microbiota (gut flora) and lead to adverse effects such as the emergence of bacterial resistance or the occurrence antibiotic-associated diarrhoea (AAD) including antibiotic-induced C. difficile infection (CDI). The spread of resistant Gram-negative bacteria and the increasing number and severity of CDI are considered as worldwide public health threats. Da Volterra is a biotechnology company developing a novel product, DAV132 (a medical device in Europe), intended to prevent these antibiotic adverse effects. Da Volterra is planning to carry out a phase 2-3 randomized controlled trial (RCT) of DAV132 in the prevention of antibiotic-induced CDI. The RCT will involve hospitalized patients aged ≥50 years old and treated with predefined antibiotic classes known to increase the risk of CDI. The incidence of CDI in this population is unknown, yet, incidence is an important determinant for the required sample size. Therefore, the main objective of the current study is to assess CDI incidence in patients ≥50 years of age treated with predefined antibiotic classes. In addition, to optimise the target population of the DAV132 RCT, the effect of the predefined antibiotic agents on the intestinal microbiota will be assessed. Furthermore, biomarkers predictive of CDI occurrence might help identify patients at high risk for the disease, which could further optimise the RCT. No validated biomarkers have been described in the literature yet. Assessment of potential biomarkers is another aim of the present study.

Study Population

Patients aged 50 or older receiving oral or intervenous antibiotic treatment with Third or fourth generation cephalosporins, Fluoroquinolones, Penicillins +beta-lactamase inhibitors, Clindamycin, or Carbapenems during hospitalization.

You may qualify if:

  • Male or female hospitalized patient.
  • Aged ≥ 50 years old.
  • Initiation of intravenous or oral treatment with intended duration ≥5 days (≥1 day for clindamycin) with at least one of the following antibiotic classes, or treatment scheduled within the next 72 hours:
  • Third or fourth generation cephalosporins
  • Fluoroquinolones
  • Penicillins +beta-lactamase inhibitors
  • Clindamycin
  • Carbapenems

You may not qualify if:

  • Patient with stoma.
  • Subject has been included into this study previously.
  • Patient treated with probiotics to prevent CDI.
  • Patient with any social or logistical condition which in the opinion of the investigator may interfere with the conduct of the study, such as incapacity to well understand, not willing to collaborate, or cannot easily be contacted after discharge.
  • Subject is subject to legal protection.
  • Subject deprived of liberty by judicial or administrative decision.
