FDA Accepts Synergy sNDA for Trulance

FDA has accepted for review a Synergy Pharmaceuticals supplemental NDA for Trulance (plecanatide) for treating adults with irritable bowel syndrome with constipation. The user fee review target date is 1/24/2018. Trulance is currently approved for treating adults with chronic idiopathic constipation.


The submission is based on data from two randomized, 12-week, double-blind, placebo-controlled Phase 3 studies where Trulance 3mg and 6mg doses met the primary endpoint showing statistical significance in the percentage of patients who were overall responders compared to placebo, according to the company. FDA defines an overall responder as a patient who fulfills both a 30% reduction in worst abdominal pain and an increase of at least one complete spontaneous bowel movement over baseline in the same week for at least 50% of the 12 treatment weeks.
