Differences in GLMM model estimates were evaluated for statistical significance at days 28, 56, and 84 to summarize outcomes after 1, 2, and 3 months of treatment, respectively. Note that interpretation of treatment group effects for GLMMs depends on the link function used. Therefore, all models of binary outcomes result in effects that are odds ratios, count variable models result in risk ratios, and normally distributed variable models using the identity link function http://www.selleckchem.com/products/BKM-120.html have the usual interpretation of effects being mean differences. Post-hoc FDA response based on daily responder criteria—where

patients must have met both WAP and stool consistency response criteria on a given day—was evaluated during the full 12-week interval and each monthly interval using a logistic regression model, controlling for baseline values of WAP, stool consistency scores, and bowel movement frequency. Minimal compliance criteria of 70% were

required within the intervals analyzed; patients with <60 diary entries during the 12-week interval were categorized as nonresponders for the study and patients with <20 diary entries during any 4-week interval were categorized as nonresponders for that month. No imputation of data was performed if a diary entry was missed. All authors had access to the study data and reviewed and approved the final manuscript. Of the 807 patients randomized, 525 patients completed the trial and 282 discontinued treatment (Supplementary Figure 1). Reasons for discontinuation included 54 patients who were noncompliant with the daily IVRS, 43 patients who voluntarily withdrew, 42 patients

Belnacasan research buy who experienced adverse events, and 38 patients in the 5-mg eluxadoline group who discontinued when the treatment arm was deselected because of lack of efficacy. Discontinuations due to adverse events were more common among patients receiving 200 mg eluxadoline. Eighteen patients were enrolled at a site terminated by Furiex for potential scientific misconduct identified during routine site auditing and were excluded from analysis. Of the Fludarabine remaining 789 patients randomized, 771 patients received at least 1 dose of study drug (safety set) and 754 received at least 1 dose of study drug and had at least 1 post-randomization assessment of the primary outcome (intent-to-treat set). Baseline characteristics in the intent-to-treat set were similar across groups, although patients in the 100-mg eluxadoline group had a slightly higher mean baseline pain score (Table 1). Patients averaged 4 to 5 bowel movements per day. More than 60% of patients demonstrated baseline IBS-SSS means indicative of severe symptoms (ie, scores >300).14 Evaluating the prespecified primary end point at week 4 (Table 2), significantly more patients in the intent-to-treat population receiving 25 mg (12.0%; P = .041) and 200 mg eluxadoline (13.8%; P = .
