About this study
Official title: A Prospective Randomized Control Trial of The Effectiveness of Alvimopan as a Rescue Treatment of Postoperative Ileus Following Colorectal Surgery
This study aims to evaluate the cost effectiveness of Alvimopan as rescue therapy in patients undergoing colorectal or small bowel resection who develop POI, and its safety and effectiveness in reducing LOS and POI duration.
This will be a prospective randomized control trial with a total of 58 patients, 29 in each group. Patients who undergo laparoscopic or open colorectal resection, small bowel resection, or ileostomy reversal with small bowel resection that subsequently develop postoperative ileus will be eligible for enrollment. If they meet inclusion/exclusion criteria, they will be randomized at the time of diagnosis of postoperative ileus to receive Alvimopan as rescue therapy or to receive conservative standard care.
Patients randomized to the study group will be given a maximum of 3 doses of Alvimopan 12mg orally, 12 hours apart. Alvimopan will be given from the time of diagnosis of postoperative ileus to the time of return of bowel function or the maximum 3 doses. Subsequent Alvimopan doses will be given if there is no return of bowel function or if symptoms of distension and/or nausea persist despite some return of bowel function.
Read the detailed description
This study aims to evaluate the cost effectiveness of Alvimopan as rescue therapy in patients undergoing colorectal or small bowel resection who develop POI, and its safety and effectiveness in reducing LOS and POI duration.
Hypothesis:
The investigators hypothesize that the use of alvimopan as rescue therapy in patients undergoing colorectal and small bowel resection surgery who develop POI can shorten their duration of POI and hospital length of stay.
Objectives:
To perform a prospective RCT to evaluate the effect of alvimopan as rescue therapy compared to standard of care in reducing the duration of post-operative ileus and post-operative LOS after colorectal and small bowel resection surgery.
Protocol:
This will be a prospective randomized control trial with a total of 58 patients, 29 in each group. Patients who undergo laparoscopic or open colorectal resection, small bowel resection, or ileostomy reversal with small bowel resection that subsequently develop postoperative ileus will be eligible for enrollment. If they meet inclusion/exclusion criteria, they will be randomized at the time of diagnosis of postoperative ileus to receive Alvimopan as rescue therapy or to receive conservative standard care.
At the time of diagnosis of postoperative ileus and after enrollment and randomization, all patients will be returned to NPO status. Nasogastric tubes (NGT) may be placed for gastric decompression at the discretion of the surgical team if clinically indicated. In the event that an NGT is placed, medications will be given orally or via the NGT, which will be clamped for 30 minutes after administration. Patients will continue on standard ERAS pathways with the exception of reduction of diet. Antiemetics will be given as clinically indicated; however, no prokinetic or promotility agents will be given as scheduled dosages.
Patients randomized to the study group will be given a maximum of 3 doses of Alvimopan 12mg orally, 12 hours apart. Alvimopan will be given from the time of diagnosis of postoperative ileus to the time of return of bowel function or the maximum 3 doses. Subsequent Alvimopan doses will be given if there is no return of bowel function or if symptoms of distension and/or nausea persist despite some return of bowel function.
All patients will follow a standard ERAS pathway after surgery, with early feeding and ambulation, along with opioid minimizing measures as is our standard postoperative protocol.
The patient and surgical team will be able to know which arm of the study the patient is in based on documentation in the medical record of the administration of Alvimopan.
Standard discharge criteria will be applied to all patients, including: Passage of stool, Ability to tolerate solid food and to drink comfortably, Adequate oral analgesia, Patient's willingness to be discharged.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study aims to evaluate the cost effectiveness of Alvimopan as rescue therapy in patients undergoing colorectal or small bowel resection who develop POI, and its safety and effectiveness in reducing LOS and POI duration.
This will be a prospective randomized control trial with a total of 58 patients, 29 in each group. Patients who undergo laparoscopic or open colorectal resection, small bowel resection, or ileostomy reversal with small bowel resection that subsequently develop postoperative ileus will be eligible for enrollment. If they meet inclusion/exclusion criteria, they will be randomized at the time of diagnosis of postoperative ileus to receive Alvimopan as rescue therapy or to receive conservative standard care.
Patients randomized to the study group will be given a maximum of 3 doses of Alvimopan 12mg orally, 12 hours apart. Alvimopan will be given from the time of diagnosis of postoperative ileus to the time of return of bowel function or the maximum 3 doses. Subsequent Alvimopan doses will be given if there is no return of bowel function or if symptoms of distension and/or nausea persist despite some return of bowel function.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Alvimopan in people with Ileus and Gastrointestinal Dysfunction, run by Scott Steele 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 10 inclusion and 8 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 20 Aug 2025. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 20 Aug 2025). 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?
Hospital Length of Stay (time frame: up to 30 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
