Arm | Intervention/treatment |
---|---|
Experimental: DAV132 group
Patients randomized to the DAV132 arm will be administered DAV132 concomitantly with fluoroquinolones.
|
Device: DAV132
DAV132:
DAV132 is regulated as a medical device in Europe and as a drug in the United States of America. |
No Intervention: No DAV132 group
Patients randomized to the No DAV132 arm will receive only fluoroquinolones, according to local standard of care.
|
- Safety endpoint: Proportion of patients having at least one adverse event (AE) related to DAV132 and/or to fluoroquinolones (FQs) and which relationship to product (DAV132 or FQ) is confirmed by the Independent Adjudication Committee (IAC). [ Time Frame: 51 days after randomization ]The IAC will review AEs according to the IAC charter, including Clostridium difficile infection (CDI) and antibiotic-associated diarrhea (AAD), in a blinded manner across both treatment groups, and confirm whether each AE is related or not to DAV132 and/or to the FQ received by the patient.
- Safety endpoint: Number of AEs and proportion of patients with at least one AE [ Time Frame: 51 days after randomization ]
- Efficacy/performance endpoint, clinical:Proportion of patients with CDI [ Time Frame: 51 days after randomization ]
- Efficacy/performance endpoint, clinical: Proportion of patients with AAD [ Time Frame: 51 days after randomization ]
- Efficacy/performance endpoint, clinical: Plasma levels of FQs [ Time Frame: Day 4 ]
- Efficacy/performance endpoint, biological: Level of free fecal concentrations of FQs [ Time Frame: Day 1, Day 4, Day 6, 10 days after the end of FQs ]Duration of treatment with FQs ranges from 5 to 21 days, at the discretion of the Investigator
- Efficacy/performance endpoint, biological: Level of α-diversity of the intestinal microbiota [ Time Frame: Day 1, Day 6, 10 days after the end of FQs, and 30 days after the end of FQs ]Duration of treatment with FQs ranges from 5 to 21 days, at the discretion of the Investigator
- Efficacy/performance endpoint, biological: Change from D1 of α-diversity of the intestinal microbiota [ Time Frame: Day 6, 10 days after the end of FQs, and 30 days after the end of FQs ]Duration of treatment with FQs ranges from 5 to 21 days, at the discretion of the Investigator
- Efficacy/performance endpoint, biological: Levels of β-diversity of the intestinal microbiota [ Time Frame: Day 6, 10 days after the end of FQs, and 30 days after the end of FQs ]Duration of treatment with FQs ranges from 5 to 21 days, at the discretion of the Investigator
- Efficacy/performance endpoint, biological: Proportion of patients with resistant bacteria and/or yeasts in feces [ Time Frame: Baseline and up to 10 days after the end of FQs ]Duration of treatment with FQs ranges from 5 to 21 days, at the discretion of the Investigator
- Efficacy/performance endpoint, biological: Proportion of patients with at least one occurrence of resistant bacteria and yeasts in feces (among patients negative at baseline) [ Time Frame: up to 10 days after the end of FQs ]Duration of treatment with FQs ranges from 5 to 21 days, at the discretion of the Investigator
- Efficacy/performance endpoint, biological: Proportion of patients with acquisition of intestinal colonization by C. difficile (among patients negative at baseline) [ Time Frame: up to 10 days after the end of FQs ]Duration of treatment with FQs ranges from 5 to 21 days, at the discretion of the Investigator
