Assessment of a Novel Fixed-dose Combination (FDC) Drug VR-AD-1005 for the Treatment of Acute Watery Diarrhea in Cholera: a Phase II, Randomized, Placebo-controlled, Double-blinded Efficacy and Safety Trial

Cholera still remains a global public health concern affecting both children and adults, and patients can succumb in quick time if remain untreated. Cholera is a secretory diarrhea and is generally treated with oral or intravenous rehydration therapy to compensate for the fluid loss. However, antimicrobial treatment is given to patients with moderate to severe diarrhea. The consistent emergence of multidrug-resistant bacteria is a major concern for the management of infectious diseases including cholera. No antisecretory drug has so far been proven successful. In a phase II clinical trial, the investigators will assess the effectiveness of a novel antisecretory drug VR-AD-1005 for treating cholera. Changes in stool volume and rehydration therapy will be assessed for VR-AD-1005 in comparison with placebo. If successful, this will be a huge advance in managing cholera and other secretory diarrhea. The introduction of the antisecretory drug can minimize the hospital stay and reduce antibiotic use, which in turn can reduce the emergence of antibiotic resistance among pathogens

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Stool Output Volume During Treatment Period.
Time Frame: Stool output volume was measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours, e.g. hour 1, hour 6, hour 8, hour 10, hour 11, hour 22, hour 23, hour 26, etc.).
Means of stool output data expressed as ml/kg·h-1 for Treatment and Comparator groups.
Stool output volume was measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours, e.g. hour 1, hour 6, hour 8, hour 10, hour 11, hour 22, hour 23, hour 26, etc.).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Duration of Stool Output in Excess of 200 ml/Hour
Time Frame: 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.
Stool output volume was measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours).
Number of Unscheduled IV Rehydration Episodes Per Treatment
Time Frame: Unscheduled IV rehydration episodes were measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours).
Average number of unscheduled IV rehydration episodes per participant per study arm.
Unscheduled IV rehydration episodes were measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours).
Volume of IV Rehydration, ml/kg
Time Frame: 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.
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).
Time Until Last Liquid Stool
Time Frame: 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.
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).
Duration of Stool Output in Excess of 400 mL/Hour
Time Frame: 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 400ml/hour was calculated for each participant and compared for control and study intervention groups.
Stool output volume was measured and recorded hourly for each participant for the entire duration of treatment (from enrollment up to 72 hours).
Participants With at Least One Adverse Event
Time Frame: From enrollment until the end of follow-up, up to 28 days
Proportion of participants experiencing at least one adverse event (including serious adverse events) following administration of study treatment during the safety evaluation period.
From enrollment until the end of follow-up, up to 28 days
