Study summary

The purpose of this study is to investigate the ability of alvimopan to reduce the time to return of bowel function in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. Half of the participants will receive alvimopan or and half will receive placebo immediately before and for up to seven days after surgery.

Read the detailed description

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a surgical procedure to treat cancer that has spread to the lining of the abdominal cavity (peritoneal metastases). It is associated with a prolonged time for return of bowel function after surgery.

Alvimopan is a drug used to speed up the time for return of bowel function after surgery. It works by blocking the opioid receptors in the gastrointestinal tract, which normally slow down bowel function in patients receiving postoperative opioid pain medication. It has not previously been tested in patients undergoing CRS/HIPEC.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Ability to understand and the willingness to sign a written .
  • Scheduled to undergo open (non-minimally invasive) CRS/HIPEC.
  • Scheduled to receive postoperative pain management with intravenous opioids.
  • Age > 18 years.
  • (ECOG) Performance Status ≤ 2.
  • Women of with negative pregnancy test prior to initiating study drug dosing.

Exclusion criteria

Exclusion Criteria:

  • Greater than 7 days of consecutive opioid use immediately prior to scheduled surgery.
  • Class C hepatic impairment.
  • End-stage renal disease ( \< 15 mL/min/1.73 m2 and/or on peritoneal dialysis or hemodialysis).
  • Complete mechanical bowel obstruction.
  • or inability to tolerate oral medication postoperatively.
  • Presence of gastrointestinal ostomy after CRS/HIPEC.
  • Pancreatic or gastric anastomosis performed during CRS/HIPEC.
  • History of allergic reactions or attributed to compounds of similar chemical or biologic composition as alvimopan at the treating investigators discretion.
  • Severe or uncontrolled medical disorder that would, in the investigator's opinion, impair ability to receive study treatment (i.e. uncontrolled diabetes, chronic renal disease, chronic pulmonary disease or active, uncontrolled infection, psychiatric illness/social situations that would limit compliance with study requirements).
  • History of myocardial infarction in the 12 months prior to scheduled surgery.
  • Pregnant or nursing.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Time to Return of Upper and Lower GI Function

    The later of the time from surgery that the participant first tolerates solid food and the time that the participant first passes a bowel movement.

    Time frame: from surgery to discharge (generally no longer than two weeks)

  1. Prolonged Ileus

    The proportion of patients who do not pass flatus or bowel movement greater than 7 days from the time of surgery.

    The time from surgery until: * The time to first flatus * The time to first bowel movement * The time to tolerance of solid food

    Time frame: from surgery to discharge (generally no longer than two weeks)

  3. Time to Discharge

    The time from surgery until discharge order written.

    Time frame: from surgery to discharge (generally no longer than two weeks)

  4. Serious Adverse Events

    The number and proportion of serious adverse events.

    Time frame: up to 30 days from surgery

  5. Subgroup Analyses

    All primary and secondary outcomes will be measured in the following subgroups: * 0 vs. 1 or greater bowel anastomoses * 0 vs. 1 or greater visceral resections * high vs. low amount of postoperative opioid use * epidural vs. no epidural

    Time frame: up to 30 days from surgery

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 18, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
