A Safety and Efficacy Study of a Range of Linaclotide Doses Administered Orally to Children Ages 7-17 Years, With Irritable Bowel Syndrome With Constipation
a study on Irritable Bowel Syndrome
The purpose of this study is to evaluate the safety and efficacy of linaclotide for the treatment of Irritable Bowel syndrome with Constipation (IBS-C), in children age 7-17 years. This study includes up to a 4-week Screening Period, and a 2 to 3-week Pretreatment Period. Patients age 7-11 will receive oral liquid or oral solid capsule and patients 12-17 will receive solid oral capsule formulation. Children ages 7-11 years meeting the entry criteria will be randomized to 1 of 3 doses of linaclotide or placebo for 4 weeks. Children ages 12-17 years meeting the entry criteria will be randomized to 1 of 4 doses of linaclotide or placebo for 4 weeks. This 4-week study will assess the effects of linaclotide on bowel movement frequency, as well as other bowel symptoms of IBS-C.
