Inclusion Criteria:

1. Signed and dated written Informed Consent obtained.
2. Males or females.
3. Aged 40-75 years.
4. Indication for full colonoscopy for colorectal cancer screening or investigation, including subjects presenting suggestive symptoms and who need a differential diagnosis.
5. Colonoscopy naïve subjects, i.e. who never underwent colonoscopy before, will be eligible, as well as non-naïve subjects who have previously undergone unsedated colonoscopy , or who had sedated colonoscopy at least 10 years prior (i.e. ≥ 10 years) to enrolment
6. Eligible for a procedure without sedation.
7. Able to complete questionnaires and use a Visual Analog Scale (VAS), including sufficient English, French or Spanish speaking skills as well as adequate eyesight and hearing
8. BMI ≥ 19, BMI ≤ 40 kg/m2.

Exclusion Criteria:

1. Known allergy or intolerance to trimebutine (Modulon® or generic).
2. Known allergy or intolerance to sulfur-containing drugs (e.g. N-acetylcysteine or captopril).
3. Previous gastrointestinal or gynecologic surgery, e.g. ileostomy, pelvic surgery,; however, patients with an appendectomy are eligible.Patients who have had a tubal ligation at least 10 years prior (i.e. ≥ 10 years) to enrolment are also eligible.
4. Diagnosed Inflammatory Bowel Disease (IBD).
5. Visceral hypersensitivity conditions such as Irritable Bowel Syndrome (IBS).
6. Clinically significant renal and/or hepatic impairment.
7. History of peritonitis.
8. Known severe diverticular disease.
9. Severe diverticulosis as documented by prior imaging series
10. Known or suspected stenosis of the colon.
11. Chronic pain syndrome such as fibromyalgia and endometriosis.
12. Any clinically-relevant abnormality identified on the screening, history, physical examination, 12-lead ECG or laboratory examination, which would, in the Investigator's opinion, preclude the administration of investigational drug product, GIC1001
13. Unexpected and significant visceral pain reported by subject prior to colonoscopy.
14. Dementia.
15. Diagnosed clinically significant psychiatric illness, including severe anxiety disorders that may affect the subject's perception of visceral pain or ability to participate in the study.
