| NCT01241552 | A Study of MK-3415, MK-6072, and MK-3415A in Participants Receiving Antibiotic Therapy for Clostridium Difficile Infection (MK-3415A-001) | PHASE3 | COMPLETED | 1,452 | — | — | Oct 10, 2011 | Dec 9, 2014 | Sep 5, 2018 | - | — |
CDI recurrence is defined as the development of a new episode of diarrhea (3 or more loose stools in 24 or fewer hours) and a positive local or central lab stool test for toxigenic Clostridium (C.) difficile following clinical cure of the initial CDI episode
An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended signs (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specific procedure, whether or not considered related to the medicinal product or protocol specific procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.

A drug-related AE was an AE determined by the investigator to be related to the drug.
A SAE is any AE occurring at any dose or during any use of Sponsor's product that: results in death; or is life threatening; or results in a persistent or significant disability/incapacity; or results in or prolongs an existing inpatient hospitalization; or is a congenital anomaly/birth defect; or is a cancer, or is associated with an overdose (whether accidental or intentional); or is other important medical events.

A serious drug-related AE was a SAE determined by the investigator to be related to the drug.

Infusion-specific AEs included local infusion site AEs; and systemic AEs which include nausea, vomiting, chills, fatigue, feeling hot, infusion site conditions (bruising, coldness, erythema, extravasation, pain, phlebitis, pruritus), pyrexia, arthralgia, musculoskeletal pain, myalgia, dizziness, headache, dysphonia, nasal congestion, pruritus, rash, pruritic rash, urticaria, flushing, hot flush, hypertension, and hypotension.

| Name | Type | Description |
|---|---|---|
| MK-3415 | BIOLOGICAL | A single IV infusion of MK-3415 (10 mg/kg of monoclonal antibody to Clostridium difficile Toxin A) |
| MK-6072 | BIOLOGICAL | A single infusion of MK-6072 (10 mg/kg of monoclonal antibody to Clostridium difficile Toxin B) |
| MK-3415A | BIOLOGICAL | A single IV infusion of MK-3415A (10 mg/kg of monoclonal antibody to Clostridium difficile Toxin A and 10mg/kg of monoclonal antibody to Clostridium difficile Toxin B) |
| Placebo | BIOLOGICAL | A single IV infusion of normal saline (0.9% sodium chloride) |
| SOC | DRUG | Standard of care (SOC) for CDI will be prescribed for 10 to 14 days and can begin on the day of study drug infusion; but the first dose must have been administered prior to or within a few hours following study drug infusion. SOC is defined as the receipt of oral metranidazole, oral vancomycin, IV metronidazole concurrent with oral vancomycin, oral fidaxomicin, or oral fidaxomicin concurrent with IV metronidazole. |

A positive test for toxigenic C. difficile from a stool collected no more than 7 days before study infusion. * participant must...
