Brief Summary:
The purpose of this study is to determine the safe use and evaluate the efficacy/performance of DAV132 in hospitalized patients at high risk for Clostridium difficile infection (CDI) and who receive fluoroquinolones (FQs) for the treatment of acute infections or for prophylaxis of febrile neutropenia.

Condition or disease Intervention/treatment Phase
Clostridium Difficile Infection Device: DAV132 Not Applicable

Detailed Description:
Da Volterra develops DAV132, a novel therapeutic option preserving the intestinal microbiota, to prevent potentially life-threatening conditions such as CDI or emergence of antibiotic-resistant bacteria. Prevention of CDI remains critical unmet need, especially for patients at high risk of developing such infection.

Actual Enrollment : 260 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A European Multicenter, Randomized, Parallel-group Study to Evaluate the Safety and Efficacy/Performance of DAV132 in Hospitalized Patients at High Risk for Clostridium Difficile Infection and Who Receive Fluoroquinolones for the Treatment of Acute Infections
Actual Study Start Date : October 31, 2018
Actual Primary Completion Date : August 9, 2019
Actual Study Completion Date : August 9, 2019

Arm Intervention/treatment
Experimental: DAV132 group
Patients randomized to the DAV132 arm will be administered DAV132 concomitantly with fluoroquinolones.
Device: DAV132

DAV132:

  • Dosage: 15 g/day activated charcoal (22.5 g/day DAV132)
  • Route: Oral
  • Duration: duration of fluoroquinolone treatment + 2 days

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.



Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. Safety endpoint: Number of AEs and proportion of patients with at least one AE [ Time Frame: 51 days after randomization ]
  2. Efficacy/performance endpoint, clinical:Proportion of patients with CDI [ Time Frame: 51 days after randomization ]
  3. Efficacy/performance endpoint, clinical: Proportion of patients with AAD [ Time Frame: 51 days after randomization ]
  4. Efficacy/performance endpoint, clinical: Plasma levels of FQs [ Time Frame: Day 4 ]
  5. 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

  6. 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

  7. 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

  8. 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

  9. 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

  10. 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

  11. 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
