Linzess Approved for Pediatric Constipation
FDA has approved an Ironwood Pharmaceuticals supplemental NDA for Linzess (linaclotide) to treat functional constipation in pediatric patients aged six to 17 years. Linzess is the first treatment for this condition and the recommended dosage is 72 mcg orally once daily, according to an agency release. Commonly experienced by children and adolescents, FDA says functional constipation is characterized by infrequent bowel movements with hard stools that can be difficult or painful to pass.
Approval is based on data from a 12-week placebo-controlled clinical trial (Trial 7; NCT04026113) and supported by efficacy data from adequate and well-controlled trials in adults with chronic idiopathic constipation, the release says. The primary efficacy endpoint was a 12-week change from baseline in spontaneous bowel movement (SBM) frequency rate. “Patients who received Linzess experienced a greater improvement in the average number of SBMs per week than patients who received placebo,” FDA says.
On the safety side, The most common adverse reaction reported was diarrhea. “If severe diarrhea occurs, patients should stop receiving Linzess and be rehydrated,” FDA says.
