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   44020   clinical trials with a EudraCT protocol, of which   7318   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.

    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To determine whether MK-3415A given with the standard of care antibiotic therapy (SOC) relative to MK-6072 and placebo given with SOC reduces CDI recurrence over a period of 12 weeks and to evaluate the safety profile of a single infusion of monoclonal antibody therapy compared to placebo.
    E.2.2Secondary objectives of the trial
    To determine the proportion of patients with global cure (defined as clinical cure of the initial episode and no CDI recurrence through Week 12) in the treatment group receiving MK3415A given with SOC compared to the treatment group receiving placebo and SOC.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Participant must be 18 years of age or older.
    2. Patient has a confirmed diagnosis of C. difficile infection (CDI) defined as:
    a. Diarrhea (passage of 3 or more loose stools in 24 or fewer hours [16],
    AND
    b. A positive stool test for toxigenic C. difficile from a stool sample collected no
    more than 7 days before the study infusion (allowed stool test methods and kits
    are listed in Protocol Appendix 6.1).
    NOTE: Diarrhea is not required to be present on the day of infusion.
    3. Participant must be receiving SOC therapy for CDI. SOC therapy is defined as the receipt of oral metronidazole, oral vancomycin, IV metronidazole concurrent with oral vancomycin, oral fidaxomicin, or oral fidaxomicin concurrent with IV metronidazole.
    4. Participant is highly unlikely to become pregnant or to impregnate a partner since they meet at least one of the following criteria: a. A female participant who is not of reproductive potential is eligible without requiring the use of contraception.
    A female participant who is not of reproductive potential is defined as: one who has either (1) reached natural menopause (defined as 6 months of spontaneous amenorrhea with serum follicle stimulating hormone (FSH) levels in the postmenopausal range as determined by the local laboratory, or 12 months of spontaneous amenorrhea); (2) 6 weeks post surgical bilateral oophorectomy with or without hysterectomy; or (3) bilateral tubal ligation. Spontaneous amenorrhea does not include cases for which there is an underlying disease that causes amenorrhea (e.g. anorexia nervosa). b. A participant who is of reproductive potential agrees to remain abstinent or use (or have their partner use) 2 acceptable methods of birth control starting at enrollment and through the 12 Week study period. Acceptable methods of birth control are: intrauterine device (IUD), diaphragm with spermicide, contraceptive sponge, condom, vasectomy and any registered and marketed hormonal contraceptives that contain an estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or intramuscular agents)
    5. Participant or legal representative must have voluntarily agreed to participate by providing written informed consent after the nature of the study has been fully explained.
    E.4Principal exclusion criteria
    1. Patient with an uncontrolled chronic diarrheal illness such as, but not limited to,
    uncontrolled ulcerative colitis or Crohn's disease or with a condition such that their
    normal 24-hour bowel movement habit is 3 or more loose stools as defined by the
    Bristol Stool Chart Types 5, 6 or 7 (see Appendix 6.2). Patients with a history of inflammatory bowel disease who are controlled (i.e., had no recent active diarrhea prior to current C. difficile episode) may be enrolled if in the opinion of the
    investigator the symptoms are more likely due to CDI than a flare of the
    inflammatory bowel disease.
    2. Participant with a planned surgery for CDI within 24 hours.
    3. Participant has a positive pregnancy test in the 48 hours before the infusion or is unwilling to undergo pregnancy testing if a pre-menopausal female who is not sterilized and therefore has the potential to bear a child.
    4. Participant is breast-feeding or plans to breastfeed prior to the completion of the 12-week study period.
    5. A female participant who plans to donate ova prior to the completion of the 12-week study period, or a male participant who is planning to impregnate or provide sperm donation prior to the completion of the 12-Week study period.
    6. Patient has previously participated in this study, has previously received MK-3415 or
    MK-6072 (either alone or in combination), has received a C. difficile vaccine, or has
    received any other experimental monoclonal antibody against C. difficile toxin A or B.
    7. Participant plans to donate blood and/or blood products within 6 months following the infusion.
    8. Participant has received immune globulin within 6 months prior to receipt of the infusion or is planning to receive immune globulin prior to the completion of the 12-week study period.
    9. Treatment with SOC therapy is planned for longer than 14 days.
    10. Patient has received more than a 24-hour regimen of cholestyramine, cholestimide, rifaximin, or nitazoxanide within 14 days prior to receipt of the infusion or is planning to receive these medications prior to the completion of the 12-Week study period.
    11. Patient plans to take medications which are given to decrease gastrointestinal
    peristalsis, such as loperamide (ImodiumTM), or diphenoxylate hydrochloride/atropine sulfate (LomotilTM), at any time during the 14 days following infusion. Patients receiving opioid medications at the onset of diarrhea may be included if they are expected to be on stable doses of these medications, or there is anticipation of a dose decrease or cessation of their use.
    12. Patient plans to take the probiotic Saccharomyces boulardii or plans to receive fecal transplantation therapy, or any other therapies that have been demonstrated to decrease CDI recurrence at any time following infusion (Day 1) and through the
    completion of the 12-Week study period (all such therapies would be allowed if
    recurrence occurs after study therapy/SOC has completed, see Section 3.2.1.2).
    13. Patient has received another investigational study 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 study period.
    14. Participant is not expected to survive for 72 hours.
    15. Participant has any other condition that, in the opinion of the investigator, would jeopardize the safety or rights of the participant participating in the study, would make it unlikely for the participant to complete the study, or would confound the results of the study.
