CAMBRIDGE, Mass.--(BUSINESS WIRE)--Ironwood Pharmaceuticals, Inc. (NASDAQ: IRWD) today announced that its European partner Almirall, S.A. submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for linaclotide, a guanylate cyclase type-C (GC-C) agonist, for the treatment of irritable bowel syndrome with constipation (IBS-C). The submission includes efficacy and safety data from a Phase 3 program comprising two double-blind placebo-controlled trials measured against the endpoints required by the EMA and two open-label long term safety studies. A total of more than 1,600 patients with IBS-C received a once-daily dose of either linaclotide or placebo across the two Phase 3 clinical trials. In these trials, statistically significant improvements in abdominal and bowel symptoms were achieved for linaclotide-treated patients versus placebo-treated patients for the co-primary and secondary endpoints.
