Trulance NDA Approved for Expanded Indication
FDA has approved a Synergy Pharmaceuticals NDA for Trulance (plecanatide) 3 mg tablet for the once-daily treatment of irritable bowel syndrome with constipation (IBS-C) in adults. The drug was previously approved for treating adults with chronic idiopathic constipation (CIC).
Approval was based on data from the company’s Phase 3 IBS-C program that included two randomized, 12-week, double-blind, placebo-controlled trials. In both, Trulance met the primary endpoint as compared with placebo, according to the company, adding that patients who received the drug “experienced significantly reduced abdominal pain and improvements in stool frequency, stool consistency, and straining with bowel movements during the 12-week treatment period as compared to placebo.”
On the safety side, the most common adverse event in the studies was diarrhea, with severe diarrhea reported in 1% of patients, Synergy says. Overall discontinuation rates were low among patients treated with Trulance and placebo (2.5% vs. 0.4% at placebo) and the most common adverse reaction leading to discontinuation was diarrhea (1.2% vs. 0% in placebo).
