A Randomized, Double-Blind, Placebo-Controlled Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of a Single Infusion of Bezlotoxumab (MK-6072, Human Monoclonal Antibody to C. Difficile Toxin B) in Children Aged 1 to <18 Years Receiving Antibacterial Drug Treatment for C. Difficile Infection (MODIFY III)
In Brief
A Phase 3 clinical trial evaluating Bezlotoxumab, Placebo, and 1 other intervention for Clostridium Difficile Infection. Completed, enrolled 148 participants across 75 sites in 17 countries.
Detailed Summary
The primary objectives of this study are to evaluate the pharmacokinetics (PK), safety, and tolerability of bezlotoxumab (MK-6072) in children aged 1 to \<18 years of age with a confirmed diagnosis of Clostridium difficile infection (CDI) who are receiving antibacterial drug treatment. The primary hypothesis is that the area under the concentration-time curve from 0 to infinity (AUC0-inf) of bezlotoxumab after treatment of pediatric participants with bezlotoxumab is similar when compared to the AUC0-inf of bezlotoxumab after treatment of adults with bezlotoxumab.

Timeline
Interventions
A single intravenous (IV) infusion of 10 mg of bezlotoxumab per kg body weight. Dose may then be changed based on results from initial 12 participants.
A single IV infusion of placebo for bezlotoxumab consisting of either 0.9% sodium chloride or 5% dextrose.
ABD will be administered for 10-21 days including the duration of ABD prior to the screening visit, during the screening period, and after the infusion of study treatment, per institutional guidelines, at the investigator's discretion. ABD is defined as the receipt of oral metronidazole, oral vancomycin, intravenous (IV) metronidazole concurrent with oral vancomycin, oral fidaxomicin, or oral fidaxomicin concurrent with IV metronidazole.
