Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy

The aim of this study is to determine tramadol´s ability to induce opioid induced bowel dysfunction by using an objective design to explore gastrointestinal transit, motility pattern, secretion, and colonic volume.

Conditions and MedDRA coding

Opioid induced bowel dysfunction

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 9

1. Healthy (assessed by a study-affiliated medical doctor.)
2. Signed informed consent.
3. Able to read and understand Danish.
4. Male (to avoid influence of menstrual cycles)
5. Northern European descent (to minimize genetic variance influences on drug metabolism).
6. The researcher believes that the participant understands the study details, is compliant and is expected to complete the study.
7. Opioid naïve (who have not taken prescription opioid for one week or longer and at least a year have passed since completion of a previous opioid study.)
8. Between 20 and 40 years of age
9. A STAI score in the range of 20-37 i.e., classified as “no or low anxiety” at inclusion.

Exclusion criteria 14

1. Known hypersensitivity or allergy towards the used pharmaceutical compounds or pharmaceutical compounds similar to those used in the study.
2. Daily alcohol consumption
3. Participation motivated by “wrongful” reasons such as poor economy, or psychosocial issues e.g., problems in the family, loneliness, sadness. People with such problems may be more likely to develop substance dependence.
4. Intake of alcohol within 48 hours before start of study period or any alcohol consumption during each study period.
5. Use of any analgesic medication within 48 hours before start as well as for the duration of the study
6. Less than three spontaneous bowel movements per week.
7. Participation in other studies within 14 days prior to first visit.
8. Expected need of medical/surgical treatment during the study.
9. Any diagnosed disease, which investigator concludes will affect the trial (including all contraindicated complications: severe chronic obstructive pulmonary disease, pulmonary heart disease, severe bronchial asthma, paralytic ileus, hypercapnia, serious respiratory depression with hypoxia, moderate to severe decreased liver function, gastrointestinal obstruction or perforation, acute surgical abdominal complications such as appendicitis, Mb. Crohn’s, ulcerative colitis, and toxic mega colon).
10. History of substance abuse (alcohol, THC, benzodiazepine, central stimulants and/or opioids, urine drug test will be performed prior to treatment start).
11. History of major mental disorders (e.g., major anxiety, major depression or treatment with psychoactive medications etc.)
12. Metal implants or pacemaker.
13. Daily use of prescription only medicine
14. Use of nicotine

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 2

1. To evaluate total gastrointestinal transit time (MTS-2)
2. To evaluate colorectal transit time

Secondary endpoints 12

1. Subjective assessments of constipation (PAC-SYM, BSFS, GSRS, BFI)
2. Diagnostic evaluation of opioid-induced constipation (Rome IV C6)
3. Subjective assessment of opiate withdrawal (SOWS)
4. Segmental transit time of the stomach, small intestine, and colonic segments (assessed with MTS-2)
5. Detailed colonic motility (assessed with MTS-2)
6. Colon volume (assessed with MRI)
7. Water content in the colon (assessed with MRI)
8. Gastric half emptying time (assessed with MRI)
9. Gastric accommodation (assessed with MRI)
10. Gastric motility (assessed with MRI)
11. Small bowel motility (assessed with MRI)
12. Small bowel water content (assessed with MRI)
