Who cannot join

  • 1.

Presence of any other significant or progressive/unstable medical condition that, in the opinion of the investigator, would compromise evaluation of the trial treatment or may jeopardise patient's safety, compliance or adherence to protocol requirements, such as significant psychiatric, cardiovascular, pulmonary, metabolic, endocrine or neurological disease.
  • 10. Any GI pathology or surgery or intractable vomiting likely to significantly influence drug absorption.
  • 11. Inability to swallow the trial medication whole (e.g. due to dysphagia). 12. Known or suspected acute or chronic alcoholism, delirium tremens, or toxic psychosis.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Where is the study taking place?

The record lists 104 sites in United Kingdom, Germany, Poland, Czechia, Serbia and 4 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
