Participant Flow

This study recruited 150 participants in total, meeting the inclusion criteria, of which 75 participants were double-blindly assigned to the Active Arm and 75 participants were assigned to the Placebo Arm.

Participants were randomized in a 1:1 ratio. VR-AD-1005 oral capsule was administered orally 4 times per day (approximately every 4-5 hours with overnight break to allow for participants rest and recovery) with first administration of 3 capsules as loading dose

SECONDARY outcome

Timeframe: Stool output volume was measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours).

For analysis, individual stool charts were used to calculate stool output per patient per hour and express it as stool volume in ml/hour. Duration of time during treatment when stool output was in excess of 200ml/hour was calculated for each participant and compared for control and study intervention groups.

SECONDARY outcome

Timeframe: Volume of administered IV rehydration solution was measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours).

Average volume of IV rehydration per subject per treatment arm was calculated as aggregate per time period. Data were analyzed for three time periods, namely 0-12 hours; 0-24 hours; and the entire duration of treatment. For each period, mean volume of the infusion was calculated and expressed in ml/kg body weight.

SECONDARY outcome

Timeframe: Liquid and solid stool output was measured by trained trial personnel and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours).

Diarrhea duration is measured from the first dose of study drug to resolution. Time (hours) from start of treatment until the last liquid stool was determined for each participant. Data were extracted from individual stool charts, and time-to-criterion was analyzed using log-rank statistics between the Treatment and the Comparator groups.
