- Conditions
- Post-Operative Ileus (POI)

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MethylnaltrexoneDrug
Also called MNTX
Methylnaltrexone will be administered as per the dose and schedule specified in the respective arms.
PlaceboDrug
Placebo matching to methylnaltrexone will be administered as per the schedule specified in the respective arm.
| Study group | Role | What they receive |
|---|---|---|
| MNTX 12 mg | Experimental | Participants will receive methylnaltrexone (MNTX) 12 milligrams (mg) as an intravenous (IV) infusion over approximately 20 minutes for every 6 hours until one of the following occurs: 1) 24 hours elapsed after the first bowel movement and the participant was tolerating clear liquids, 2) the participant was discharged from the hospital, or 3) a maximum of 10 days elapsed. The first dose of study drug will be administered within the first 90 minutes after the end of surgery (defined as the time when the last skin suture or staple is placed in the participant). Receives: Drug: Methylnaltrexone |
| MNTX 24 mg | Experimental | Participants will receive MNTX 24 mg as an IV infusion over approximately 20 minutes for every 6 hours until one of the following occurs: 1) 24 hours elapsed after the first bowel movement and the participant was tolerating clear liquids, 2) the participant was discharged from the hospital, or 3) a maximum of 10 days elapsed. The first dose of study drug will be administered within the first 90 minutes after the end of surgery (defined as the time when the last skin suture or staple is placed in the participant). Receives: Drug: Methylnaltrexone |
| Placebo | Placebo comparator | Participants will receive placebo matching to MNTX as an IV infusion over approximately 20 minutes for every 6 hours until one of the following occurs: 1) 24 hours elapsed after the first bowel movement and the participant was tolerating clear liquids, 2) the participant was discharged from the hospital, or 3) a maximum of 10 days elapsed. The first dose of study drug will be administered within the first 90 minutes after the end of surgery (defined as the time when the last skin suture or staple is placed in the participant). Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Time to First Bowel Movement
Time to first bowel movement was measured from the end of surgery (defined as the time when the last skin suture or staple was placed in the participant). Time of the first bowel movement was recorded on the electronic case report form (eCRF). The first bowel movement was defined as a normal stool for a postoperative participant based on the clinical judgment of the investigator or designee. Analysis was performed by Kaplan-Meier estimate. Participants who had a bowel movement but were readmitted to the hospital within 1 week after discharge with a diagnosis of postoperative ileus (POI) were considered censored at the time of the first bowel movement as if the bowel movement had not occurred.
Measured: Day 1 (From the time of end of surgery [that is; from the first dose of study drug administration]) up to Day 10
Secondary outcomes (3)
Time to Discharge Eligibility
Time to discharge eligibility was measured from the end of surgery (defined as the time when the last skin suture or staple was placed in the participant). Discharge eligibility was defined as both tolerance of solid food and at least one bowel movement. Participants were considered to have tolerated solid food when they have eaten greater than or equal to (≥) 50 percent (%), of the first of two successive solid food meals (based on the judgement of the investigator or designee), without vomiting or nausea. Participants readmitted to the hospital with a diagnosis of POI within 7 days of discharge were considered treatment failures. Analysis was performed by Kaplan-Meier estimate.
Measured: Day 1 (From the time of end of surgery [that is; from the first dose of study drug administration]) up to Day 10
Time to Discharge Order Written From the End of Surgery
The investigator or designee recorded the time of the order. Participants re-admitted to the hospital with a diagnosis of POI within 7 days after discharge were considered treatment failures. Analysis was performed by Kaplan-Meier estimate.
Measured: Day 1 (From the time of end of surgery [that is; from the first dose of study drug administration]) up to Day 10
Number of Participants With Clinically Meaningful Events (CMEs) for Nausea or Retching/Vomiting at 0 or 24 Hours as Evaluated by the Opioid-Related Symptom Distress Scale (SDS)
CMEs were defined using opioid-related SDS (assessed participant-reported levels of severity concerning 10 symptoms associated with opioid medication usage: fatigue, drowsiness, inability to concentrate, nausea, dizziness, constipation, itching, difficulty with urination, confusion and retching/vomiting). CME = any symptom rated as severe (3) or very severe (4), with the exception of confusion. A total CME score was calculated by summing the number of CMEs across symptoms and ranged from 0 to 9. CME was counted for either nausea or vomiting/retching, or both and reported in this outcome measure.
Measured: 0 and 24 hours

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Methylnaltrexone in people with Post-Operative Ileus (POI), run by Bausch Health Americas, Inc. at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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?
Yes. Results are posted in the registry (first posted 4 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time to First Bowel Movement (time frame: Day 1 (From the time of end of surgery [that is; from the first dose of study drug administration]) up to Day 10). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00401375, which also lists 1 linked publication.
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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2019; AzTrials last refreshed its copy on 8 Nov 2026.
