A Safety and Efficacy Study of a Range of Linaclotide Doses Administered Orally to Children Ages 6-17 Years Who Fulfill Modified Rome III Criteria for Child/Adolescent Functional Constipation (FC)

Completed · Phase 2 · Has a placebo group

Conditions studied: Functional Constipation in Children Ages 6-17 Years

In brief

The purpose of this study was to evaluate dose response of the safety and efficacy of linaclotide for the treatment of functional constipation (FC), in children age 6-17 years. This study includes up to a 4-week Screening Period, and a 2 to 3-week Pretreatment Period. Participants age 6-11 years will receive oral liquid formulation and participants 12-17 years will receive solid oral capsule or liquid oral solution. Children ages 6-11 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 FC.

1. Improvement with defecation
2. Onset associated with a change in frequency of stool
3. Onset associated with a change in form (appearance) of stool
Participant reports having more than 1 loose, mushy stool (eDiary-recorded stool consistency of 6 on the Pediatric Bristol Stool Form Scale [p-BSFS]) or any watery stool (eDiary-recorded stool consistency of 7 on the p-BSFS) with any SBM that occurred in the absence of laxative use on the calendar day of the BM or the calendar day before the BM during the 14 days before the randomization day and up to the randomization
Select medical history or conditions that may be related to other causes of constipation or may interfere with safety and efficacy analyses
Participant has required manual or hospital-based disimpassion any time prior to randomization
Participant is unable to tolerate the placebo during the Screening Period
