Harmony Biosciences Holdings Inc shares results from two post-hoc analyses from the clinical development program for WAKIX (pitolisant) at SLEEP 2021.

One of the poster presentations is a new analysis that calculated the number needed to treat and effect size of WAKIX to demonstrate the magnitude of its clinical effectiveness. The second poster is based on an analysis of the cataplexy data from the clinical development program for WAKIX.

“The analyses that we are presenting at the SLEEP conference this year highlight the strength of the efficacy data for WAKIX,” says Harmony’s chief medical officer, Jeffrey Dayno, MD, in a release. “The analyses include both a traditional approach to presenting efficacy data, as well as one that underscores the clinical relevance of the findings, using [number needed to treat] and effect sizes to capture overall clinical benefit.”

The data being presented by Harmony will be available in the meeting’s ePoster gallery beginning June 9 through November 30, and includes:
