Post-hoc FDA response for abdominal pain was significantly greate

Post-hoc FDA response for abdominal pain was significantly greater than placebo for the 100-mg eluxadoline group, and stool consistency response displayed a more dose-proportional response with superiority over placebo observed for the 200-mg eluxadoline group (P < .10 for the

100-mg eluxadoline group). The higher dropout rate in the 200-mg eluxadoline group and lack of data imputation for those dropouts may contribute to the failure of that dose to achieve superiority over placebo for the pain responses during the 12-week study interval used in the post-hoc analyses. The most common adverse events reported were those of the gastrointestinal system. Gastrointestinal adverse events, including nausea, vomiting, and abdominal pain, were more frequently reported

in the 200-mg eluxadoline group, suggestive this website of a continuum of eluxadoline’s Selisistat purchase local pharmacological effects on the gut. The higher incidence of abdominal pain reported in the 200-mg eluxadoline group might also contribute to the lack of efficacy seen for pain response in this dose group. Although the incidence rate of constipation was higher in the 100-mg eluxadoline group, the events were generally mild in intensity and were tolerated by the patients without requiring discontinuation of study drug. The most notable safety finding among patients receiving eluxadoline was infrequent reports of pancreatitis, including 2 cases that occurred after only 1 or 2 doses of study drug. Although 2 of the 4 total pancreatitis cases were confounded by mitigating factors (one patient with high blood alcohol level at the onset of the event and another patient who was off study drug for 2 weeks at the onset of the event), a possible relationship Baf-A1 to eluxadoline treatment could not be ruled out because of the known association between opioids and acute pancreatitis and the lack of any

such events among placebo-treated patients in this study.17 After the last case, the protocol was amended to exclude patients who might have been predisposed to pancreatitis, that is, those with histories of pancreatitis, biliary duct disease, sphincter of Oddi dysfunction, alcohol abuse, binge drinking, elevated serum lipase, or cholecystectomy. The rationale for excluding patients with sphincter of Oddi dysfunction was based on the knowledge that patients experiencing sphincter of Oddi dysfunction are sensitive to opioids and can experience severe abdominal pain and pancreatitis, even after a single dose of opioid-containing medications.18 Importantly, after implementation of the amendment, no additional events of pancreatitis were reported among the 210 patients enrolled. Future studies will need to prospectively evaluate the potential association between pancreatitis and eluxadoline treatment and also evaluate whether the exclusionary precautions implemented in the current study might minimize any potential risk.
