Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43716   clinical trials with a EudraCT protocol, of which   7255   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    2. To estimate the proportion of participants with sustained clinical response over a period of 12 weeks in participants who received a single infusion of bezlotoxumab or placebo.

    4. To assess the incidence of infusion-related reactions in participants who received a single infusion of bezlotoxumab or placebo.
    5. To assess the potential for bezlotoxumab to induce immunogenicity within 12 weeks following administration of a single infusion of bezlotoxumab.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Merck will conduct Future Biomedical Research on DNA (Blood, serum/plasma and stool) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time.
    E.3Principal inclusion criteria
    1. At the time of screening, participant
    A) has suspected or confirmed CDI, as evidenced by the following: 1. had a change in normal bowel habits for 2 or more calendar days with either watery diarrhea (for participants using diapers or other type of fecal collection device, Bristol Stool Scale types 6 or 7) or at least 6 UBMs (eg, takes shape of container, or Bristol Stool Scale types 5, 6, or 7) within a 48-hour period, and 2.produced a stool sample that has tested positive for toxigenic C. difficile according to local diagnostic criteria.
    B) is receiving or is planning to receive a 10- to 21-day course of antibacterial drug treatment for CDI, which is defined as oral vancomycin, oral metronidazole, or oral fidaxomicin. Additionally, IV metronidazole may be given concurrently with oral vancomycin or oral fidaxomicin
    2. At the time of randomization/study infusion, participant: a)has a diagnosis of CDI confirmed by a diagnostic assay which detects the presence of C. difficile toxin in stool and b)is still receiving antibacterial drug treatment for CDI
    3.Participant is of either sex and of any race, and ≥1 year to <18 years of age at the time of randomization
    4. A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: a)Not a woman of childbearing potential (WOCBP) as defined in the protocol OR b) A WOCBP who agrees to use any contraceptive methodlisted in the protocol from Day 1 through at least 12 weeks after the single infusion of study treatment.
    5. The participant (or legally acceptable representative [LAR] if applicable) provides written informed consent/assent for the trial. The participant or LAR may also provide consent/assent for Future Biomedical Research (FBR). However the participant may participate in the main trial without participating in FBR
    6. Participant must be able to adhere to the study visit schedules
    7. Participant and/or parent or caregiver must be able to read, understand, and complete the daily diary
    E.4Principal exclusion criteria
    1. Participant has an uncontrolled chronic diarrheal illness such as, but not limited to, Crohn’s disease, ulcerative colitis, or with a condition such that their normal 24-hour bowel movement habit is 3 or more UBMs. Participants with a history of IBD who are controlled (ie, had no recent active diarrhea/UBMs prior to current CDI episode) may be enrolled if in the opinion of the investigator, the symptoms are more likely due to CDI than a flare of the IBD
    2. Has a known hypersensitivity to bezlotoxumab, its active substance and/or any of its excipients
    3. Participant for whom, at the time of randomization, the planned course of antibacterial drug treatment for CDI is longer than 21 days
    4. Participant has received any treatment or procedure listed in the protocol within the indicated exclusion window
    5. Participant has previously participated in this trial, has previously received bezlotoxumab, has received an experimental mAb against C. difficile toxin B, or has received a vaccine directed against C. difficile or its toxins
    6. Participant has received an investigational trial agent within the previous 30 days, or is currently participating in or scheduled to participate in any other clinical trial with an investigational agent during the 12-week trial period
    7. Participant is not expected to survive for 72 hours
    8. Participant has any other condition that, in the opinion of the investigator, would jeopardize the safety or rights of the participant, would make it unlikely for the participant to complete the trial, or would confound the results of the trial
    9. Is or has an immediate family member (eg, spouse, parent/legal guardian, sibling or child) who is investigational site or sponsor staff directly involved with this trial
