Design outcomes

Primary

MeasureTime frame
Main Objective: To investigate the ability of 3 currently available medical device products to impact on the wound healing process of recurrent herpes labialis (RHL) such that the ‘scab’ is either reduced or modified in a way that improves healing and/or symptoms. ;Secondary Objective: To assess the safety of the study products, as assessed by the incidence and severity of adverse events (AEs).;Primary end point(s): One or more of the test products to show a clinically relevant improvement on the healing of the scab phase of RHL as determined by observational assessments of cold sore lesions (amount of scab and duration of hard crust) using clinician assessed methodologies.
