Conditions

Common Cold, Cough

Brief summary

The purpose of this Real-World Evidence study is to generate real world data from participants with cough associated with the common cold, evaluating the effects in two arms with commercially available cough syrups on health-related quality of life (QoL). Arm 1 includes one cough syrup (which can be used day or night) and Arm 2 includes the daytime cough syrup and a nighttime cough syrup.

Detailed description

This is a longitudinal, randomized, decentralized, open-label study evaluating the effect on QoL factors in participants with cough associated with the common cold in two arms using Robitussin Maximum Strength in a real-world setting. A sufficient number of adult participants (approximately 372) with symptoms of common cold will be screened for eligibility. The study expects to enroll approximately 260 eligible participants with a total of 200 participants expected to complete the study, approximately 100 in each study group. Participants will be randomized into one of two study groups (at a 1:1 ratio). Participants will be recruited through targeted advertising on social media channels and participants will not be required to physically attend any on-site visits.

Adjusted Mean Change From Baseline in Wisconsin Upper Respiratory Symptom Survey-21 (WURSS-21) Total ScoreBaseline and up to Day 7 or End of Treatment (EOT)The WURSS was an evaluative illness-specific quality of life instrument, designed to assess the negative impact of acute upper respiratory infection, presumed viral (the common cold). WURSS-21 was the short version of this validated survey. Participants rated their cold symptoms (10 questions) and Quality of Life (QoL) related 9 questions using WURSS-21. The responses were evaluated on a scale ranging from 0 to 7, where 0=Do not have symptoms/Not at all and 7=Severe symptoms/Severely. Thus, the minimum and maximum possible total scores were 0 and 133 respectively, where higher total scores indicated more negative impact on symptoms and quality of life. Change from Baseline was calculated as each post-Baseline value minus Baseline value. EOT was defined as the day when the participant ceased study involvement because they no longer required relief from their cough/cold symptoms or the participant reached Day 7 (Or their last available questionnaire information).

Social Activities were assessed using 4 individual questions - Interact with others (WURSS-21: Question 19), Less comfortable in social activities (QoL: Question 1), Self-conscious around others (QoL: Question 2) and Coughing in public (QoL: Question 3). Participants rated each question and the responses were evaluated on a scale ranging from 0 to 7, where 0=Not at all and 7=Severely. The individual question score was added to derive categorized QoL score. Thus, the minimum and maximum possible total score was 0 and 28 respectively, where higher scores indicated more negative impact on QoL. Baseline was defined as Day 0. Change from Baseline was calculated as each post-Baseline value minus Baseline value.
