Article Synopsis
- Refractory GERD affects many patients, with about 30% not finding relief from traditional PPI therapy; researchers tested a new treatment called IW-3718 alongside PPIs.
- In a double-blind trial of 280 patients, those taking higher doses of IW-3718 (1500 mg) saw a significant reduction in heartburn severity and regurgitation compared to those on placebo.
- The treatment was generally well tolerated, with constipation being the most common mild side effect, and no serious drug-related adverse events reported.
Objectives: This study aimed to examine the validity of the modified Reflux Symptom Questionnaire-electronic Diary (mRESQ-eD) through patient input and psychometric testing of the questionnaire to support use in clinical trials in patients with persistent gastroesophageal reflux disease (GERD) and in accordance with Food and Drug Administration guidance on patient-reported outcome instruments.
Methods: Cognitive interviews were conducted with patients (n = 30) to evaluate the interpretability and content validity of draft mRESQ-eD items. Patient data from a phase 2b clinical study (ClinicalTrials.
Objectives: Linaclotide is a minimally absorbed guanylate cyclase-C agonist. The objective of this trial was to determine the efficacy and safety of linaclotide in patients with irritable bowel syndrome with constipation (IBS-C).
Methods: This phase 3, double-blind, parallel-group, placebo-controlled trial randomized IBS-C patients to placebo or 290 μ g oral linaclotide once daily in a 12-week treatment period, followed by a 4-week randomized withdrawal (RW) period.
Objectives: Linaclotide is a minimally absorbed peptide guanylate cyclase-C agonist. The objective of this trial was to determine the efficacy and safety of linaclotide treatment in patients with irritable bowel syndrome with constipation (IBS-C) over 26 weeks.
Methods: This phase 3, double-blind, parallel-group, placebo-controlled trial randomized IBS-C patients to placebo or 290 μg of oral linaclotide once daily for a 26-week treatment period.
Background: Linaclotide is a minimally absorbed peptide agonist of the guanylate cyclase C receptor. In two trials, we aimed to determine the efficacy and safety of linaclotide in patients with chronic constipation.
Methods: We conducted two randomized, 12-week, multicenter, double-blind, parallel-group, placebo-controlled, dual-dose trials (Trials 303 and 01) involving 1276 patients with chronic constipation.
