Outcome Measures
Primary Outcomes (1)
Comparative Weekly Change in NRS Itch Score Over the 8-week Active Treatment Period
Determine the efficacy of Serlopitant compared with placebo on reducing EB-associated daily itch score as measured by patient self-reports using a numeric rating scale (NRS) for itch severity.The NRS is comprised of one item and represents the numbers 0 ("no itch") to 10 ("worst imaginable itch"). Because itch is subjective and can vary day to day, nightly NRS scores were recorded in patients' Itch Diaries. NRS recorded by subject daily, from screening visit through the end of the study. This study was designed to detect differences between the two treatment groups. The primary endpoint was the comparative weekly change in Numeric Rating Scale (NRS) itch severity score from baseline over 8 weeks; derived from a linear mixed effects model which utilizes observations from both the treatment and placebo groups to generate an interaction term of interest. Itch severity changes from day to day and this model can more appropriately report trends in patients' itch severity with treatment.
