- •- lumpy or hard stools in at least 25% of defecations
- •- sensation of incomplete evacuation for at least 25% of defecations
- •- sensation of anorectal obstruction/ blockade for at least 25% of defecations
- •- manual manoeuvres for at least 25% of defecations (e.g. digital evacuation, support of the pelvic floor)
- •5. Willingness to stop at V2 all laxatives, enemas, stool softeners, and any other medications used to treat constipation with the exception of laxative rescue medication (i.e., bisacodyl tablets) allowed per protocol.
- •6. Patients willing and able (e.g. mental and physical condition) to participate in all aspects of the trial, including use of medication, correct and independent completion of subjective evaluations (e.g. electronic diary, eDiary), attending scheduled visits, completing telephone interviews, and compliant with all protocol requirements, as evidenced by providing signed written informed consent.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range:
- •F.1.2 Adults (18-64 years) yes

- •2. Known or suspected reason for constipation other than OIC (e.g. idiopathic, neurological, endocrine, or metabolic).
- •3. Known or suspected medical conditions that might be associated with diarrhoea, intermittent loose stools or constipation, such as faecal incontinence or irritable bowel syndrome (IBS). In case of documented suspicion of IBS or justified doubts of a long ago diagnosis, the Rome IV criteria must be applied).
- •4. Any known or suspected gastrointestinal (GI) pathology that might increase the risk of perforation, such as chronic inflammatory bowel disease (Crohn’s disease, ulcerative colitis), acute diverticulitis or history of > 1 episode of diverticulitis, intestinal obstruction or pseudo-obstruction.

- •8. 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.
- •9. Any GI pathology or surgery or intractable vomiting likely to significantly influence drug absorption.
- •10. Inability to swallow the trial medication whole (e.g. due to dysphagia).
- •11. Known or suspected acute or chronic alcoholism, delirium tremens, or toxic psychosis.
- •12. Signs and symptoms that may be related to opioid withdrawal.
