About this study
Official title: A Phase III, Multicenter, Open Label, Extension Study to Evaluate the Long-Term Safety of Renzapride 4 mg Once Daily in Women With Constipation-Predominant Irritable Bowel Syndrome (IBS-C)
The main purpose of this study is to evaluate the long-term safety and tolerability of renzapride at a dose of 4 mg taken once daily for 12 months in women with constipation-predominant irritable bowel syndrome (IBS-C).
Read the detailed description
Since IBS is a chronic condition affecting patients over many years, it is anticipated that renzapride will be prescribed and used by patients on a daily basis for long periods of time. Hence the need to understand its long-term safety and tolerability in the target population. This study is open label and so all subjects will take renzapride and will know that they are taking it. Enrolment in to this study is restricted to subjects completing a 12-week, placebo-controlled study of the effectiveness of renzapride in providing relief from IBS-C (Study no. ATL1251/038/CL).

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
