Study Endpoints
Primary Endpoints
Area Under the Concentration-Time Curve of Bezlotoxumab From Time 0 to Infinity (AUC0-inf)
Day 1 (2 hours postdose), Days 10, 29, 57, and 85

Blood samples were collected at specified intervals for the determination of AUC0-inf. AUC0-inf was defined as the area under the concentration-time curve of bezlotoxumab from time zero to infinity. Per protocol, AUC0-inf of bezlotoxumab was determined for each age cohort.

Percentage of Participants Who Experienced an Adverse Event (AE)
Up to approximately 12 weeks

An AE was defined as any untoward medical occurrence associated with the use of a drug in a participant, whether or not considered drug related. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product and does not imply any judgment about causality. Per protocol, percentage of participants with AEs in the bezlotoxumab and placebo groups were presented.

Percentage of Participants Who Discontinued Study Due to an AE
Up to approximately 12 weeks

Treatment Arms
ArmTypeDescription
BezlotoxumabEXPERIMENTALParticipants receive 10 mg of bezlotoxumab per kg body weight via a single 60-minute (±10 minutes) intravenous (IV) infusion on Day 1. Additionally, participants receive background antibacterial drug treatment (ABD) for 10-21 days per institutional guidelines, at the investigator's discretion. Dose may then be changed based on results from initial 12 participants.
PlaceboPLACEBO_COMPARATORParticipants receive placebo for bezlotoxumab consisting of either 0.9% sodium chloride or 5% dextrose via a single 60-minute (±10 minutes) IV infusion on Day 1. Additionally, participants receive background ABD for 10-21 days per institutional guidelines, at the investigator's discretion.
Interventions
NameTypeDescription
BezlotoxumabBIOLOGICALA 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.
PlaceboDRUGA single IV infusion of placebo for bezlotoxumab consisting of either 0.9% sodium chloride or 5% dextrose.
Antibacterial drug treatment (ABD)DRUGABD 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.
