Lexicon NDA for Diarrhea Drug Approved
FDA has approved a Lexicon Pharmaceuticals NDA for Xermelo (telotristat ethyl) tablets in combination with somatostatin analog (SSA) therapy for treating adults with carcinoid syndrome diarrhea that SSA therapy alone has inadequately controlled. Carcinoid syndrome occurs in less than 10% of patients with carcinoid tumors, usually after the tumor has spread to the liver, according to an FDA release. “The tumors in these patients release excess amounts of the hormone serotonin, resulting in diarrhea,” it says.
Approval was based on data from a 12-week, double-blind, placebo-controlled trial in 90 adult participants with well-differentiated metastatic neuroendocrine tumors and carcinoid syndrome diarrhea. “Those receiving Xermelo added on to their SSA treatment experienced a greater reduction in average bowel movement frequency than those on SSA and placebo,” the agency says. “Xermelo may cause constipation, and the risk of developing constipation may be increased in patients whose bowel movement frequency is less than four bowel movements per day,” it says.
