NCT04869280
Post-Marketing Study of Prucalopride Safety In Pregnancy
This study collects information on pregnant women with ongoing constipation who took prucalopride and those who did not take prucalopride. The main aim of the study is to learn if any medical problems in pregnant women or their infants might be related to taking prucalopride during pregnancy. Participants are not required to take prucalopride during the study. The study is non-interventional. Women and their infants are followed during pregnancy and for 1 year after pregnancy to collect information on maternal, pregnancy, and infant outcomes. During the study, participants will be asked questions during 3 telephone interviews; 2 during pregnancy and 1 just after their expected delivery date. Participants who took or are taking prucalopride will be asked more detailed questions about this during these interviews. All information is collected remotely, and no visits to the study site are required. Also, all participants will be asked to complete a questionnaire about their baby when their baby is about 1 year old.

A Study to Assess Adverse Events and Change in Symptoms With Linaclotide Versus Placebo in Pediatric Subjects, Ages 2 to 5 Years, With Functional Constipation
Functional constipation (FC) is a common healthcare problem in children of all ages, potentially due to genetic predisposition, inadequate fiber and fluid intake, and immobility. Currently, there are no pharmacological therapies approved for the treatment of FC. This study will assess adverse events and change in disease activity with linaclotide therapy in participants with FC. Linaclotide is an approved drug being developed for the treatment of FC in pediatric patients, ages 2 to 5, who meet modified Rome IV criteria for childhood FC. In Part 1 of this study, participants are placed in 1 of 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. All participants in Part 2 will receive linaclotide. Approximately 116 participants aged 2 to 5 years with FC will be enrolled in this study at around 45 sites worldwide. Participants will receive daily doses of oral Linaclotide capsules or matching placebo for 12 weeks in Part 1 of the study. In Part 2, the open label long-term safety extension, participants with FC who completed study intervention in Part 1 of Study M21-572 or the Phase 2 Study LIN-MD-67 will receive linaclotide for 24 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

A Study of Prucalopride in Breastfeeding Women With Constipation
Prucalopride is a medicine used to treat constipation. The main aim of the study is to measure prucalopride concentrations in breast milk. Other aims are to check the growth and development of babies breastfed by their mothers who took prucalopride and to check if the babies had any side effects. During the study, participants will provide one set of milk samples over 24 hours using an electric breast pump. Breast milk samples will be collected at home and will be shipped to the laboratory. Also, participants will be asked questions during telephone interviews every 2 months in the first year of their baby's life. They will also be asked to complete growth and development questionnaires about their baby.
