Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Study Type

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

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.

Ages Eligible for Study

6 years to 11 years (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Total Cough Count
Time Frame: Up to 6 hours post-dose
Total cough count was done by trained assessors using continuous digital video and audio recordings.
Up to 6 hours post-dose

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
Change From Baseline in Perceived Verbal Cough Severity Scale for 6 Hour Post-Dose Period
Time Frame: Baseline, 1, 2, 3, 4, 5, 6 hours post-dose
Perceived verbal cough severity score was assessed on a 5-point categorical rating scale in accordance to the question "How much have you coughed in the last hour?", where 0 = not at all, 1 = a tiny bit, 2 = a little, 3 = some and 4 = a lot. The change from baseline over the 6-hour post-dosing period calculated as the average of change from baseline [that is (i.e.) baseline value minus the post baseline value] measurements of Hour 1 to Hour 6, thus the change from baseline ranged from -4 to 4; higher score indicated a better improvement.
Baseline, 1, 2, 3, 4, 5, 6 hours post-dose
Change From Baseline in Verbal Cough Severity Scale at Hours 1, 2, 3, 4, 5 and 6
Time Frame: Baseline, 1, 2, 3, 4, 5, 6 hours
Verbal cough severity score was assessed on a 5-point categorical rating scale in accordance to the question "How much have you coughed in the last hour?", where 0 = not at all, 1 = a tiny bit, 2 = a little, 3 = some and 4 = a lot. The change from baseline values were derived by subtracting each post baseline value from the baseline value, and ranged from -4 to 4; higher score indicated a better improvement.
Baseline, 1, 2, 3, 4, 5, 6 hours
Change From Baseline in Perceived Numerical Cough Severity Scale for 6 Hour Post-Dose Period
Time Frame: Baseline, 1, 2, 3, 4, 5, 6 hour post-dose
Perceived numerical cough severity score was assessed on an 11-point categorical rating scale in accordance to the question "How much have you coughed in the last hour?", where 0 = did not cough at all and 10 = cough a lot. The change from baseline for the 6-hour post-dosing period was calculated as the average of change from baseline (i.e. baseline value minus the post baseline value) measurements of Hour 1 to Hour 6, thus the change from baseline values ranged from -10 to 10; higher score indicated a better improvement.
Baseline, 1, 2, 3, 4, 5, 6 hour post-dose
Change From Baseline in Numerical Cough Severity Scale at Hours 1, 2, 3, 4, 5 and 6
Time Frame: Baseline, 1, 2, 3, 4, 5, 6 hours
Numerical cough severity score was assessed on an 11-point categorical rating scale in accordance to the question "How much have you coughed in the last hour?", wherein 0 = did not cough at all and 10 = cough a lot. The change from baseline was derived by subtracting the post baseline value from the baseline value and ranged from -10 to 10; higher score indicated a better improvement.
Baseline, 1, 2, 3, 4, 5, 6 hours
Participants' Global Assessment of Cough: Cough Severity
Time Frame: Within 5 minutes after Hour 6
Participant global assessment of cough with the assistance of parent or legal guardian was scored on a 5-point categorical scale based on response to the question " How much have you coughed in the past 6 hours?" where 0 = not at all, 1 = a tiny bit, 2 = a little, 3 = some and 4 = a lot.
Within 5 minutes after Hour 6
Participants' Global Assessment of Cough: Relief From Cough
Time Frame: Within 5 minutes after Hour 6
Participant global assessment of cough with the assistance of parent or legal guardian was scored on a 5-point categorical scale based on response to the question "From when you woke up this morning until now, how much better is your cough?" where 0 = not at all better, 1 = a tiny bit better, 2 = a little better, 3 = better and 4 = a lot better.
Within 5 minutes after Hour 6

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
