Treatment-Free Interval: A Novel Approach to Assessing Real-World Treatment Effectiveness and Economic Impact Among Patients with Irritable Bowel Syndrome with Diarrhea.

Introduction: Objective assessment of treatment effectiveness using real-world claims data is challenging. This study assessed treatment-free intervals (TFI) as a proxy for treatment effectiveness, and all-cause healthcare costs among adult patients with irritable bowel syndrome with diarrhea (IBS-D) treated with rifaximin or eluxadoline in the USA.

Methods: Adult patients (18-64 years) with IBS-D and ≥ 1 rifaximin or eluxadoline prescription were identified in the IQVIA PharMetrics Plus database (10/01/2015-12/31/2021) and classified into two mutually exclusive cohorts (i.

Post-Hoc Exploratory Pooled Analysis of the Impact of IDP-126 Gel on QoL in Moderate-to-Severe Acne.

Acne has psychosocial effects on patient's quality of life (QoL). This post hoc exploratory analysis of pooled phase 3 data assessed the impact of investigational IDP-126 gel (for moderate to severe acne) on the Acne-Specific Quality of Life Questionnaire (Acne-QoL; exploratory endpoint in the trials).  Methods: A post hoc exploratory analysis using pooled data (N=309; age ≥13 years) was conducted to assess if 1) changes from baseline to week 12 in Acne-QoL domain scores significantly differ by treatment; 2) differences were clinically meaningful, and 3) relative importance of acne severity as measured by the Evaluator's Global Severity Score (EGSS) or lesion counts explains the changes in QoL (Acne-QoL).
