What this study is about

View original scientific description
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Participants cannot be enrolled before all inclusion criteria are confirmed.
- Female participants with an ability to voluntarily provide verbal followed by written, signed, and dated (personally or via a legally authorized representative) informed consent as applicable to participate in the study.

- Participants who are currently exclusively breastfeeding or breastfeeding with supplemental formula and/or solid food. Infants who are exclusively breastfed and do not yet eat solid food are preferred.
- Participants who are currently treated as prescribed by their physician with MOTEGRITY or RESOTRAN (generic forms of prucalopride not allowed) for functional constipation, including chronic idiopathic constipation (CIC) and irritable bowel syndrome-constipation (IBS-C), for at least 5 consecutive days at the time of taking the first breastmilk sample.
- Participants who agree to the conditions and requirements of the study including the sample collection, interview schedule, completion of developmental questionnaires, and release of medical records.
- Participants with an understanding, ability, and willingness to fully comply with study procedures and restrictions.
Exclusion criteria
- The participant will be excluded from the study if any of the following exclusion criteria are met:
- Participants who are breastfeeding an infant who: is hospitalized, has a major birth defect, or has a history of a disease that could affect absorption or drug disposition.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
