The NIPA Study: A Randomized Double-blind Control Clinical Trial Naloxegol Administration to Prevent Opioids Induced Gastrointestinal Motility Disturbance in Brain Injured PAtients
The NIPA Study Naloxegol Administration to Prevent Opioids Induced Gastrointestinal Motility Disturbance in Brain Injured PAtients (NCT05008926) is a Phase 3 interventional studying Brain Injuries, sponsored by University Hospital, Brest. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
Impaired gastrointestinal transit (IGT) especially constipation, is common among patients under mechanical ventilation, occurring in up to 80 % of the patients during the first week, and has been associated with worse outcome in intensive care unit (ICU). Although IGT in critically ill patients is multifactorial and some components are due to complex disease, there is increasing evidence that exogenous opioids contribute to bowel dysmotility. Sedatives and especially opioids are largely used in the brain injured population to control intracranial pression, reduce metabolic rate, manage or prevent seizures, and improve mechanical ventilator synchrony. Therefore, brain injured patients are particularly at risk to develop IGT. The occurrence of IGT is associated with adverse outcomes in intensive care unit. Both gastric reflux and impaired peristaltic contractions are associated with ventilator-acquired pneumonia. The actual challenge is to prevent motility disorders before it occurs. A preventive strategy could in turn reduce the occurrence of complications related to impaired gastrointestinal transit such as ventilator-acquired pneumonia, bacteremia etc. It could also reduce the complications of feed intolerance and thus reduce morbidity and mortality in ICU. Naloxegol is a polyethylene glycol derivative of naloxol, which is a derivative of naloxone and a peripherally acting µ-opioid receptor antagonist. Contrary to naloxone, naloxegol has a very low penetration into the central nervous system, therefore it could be a relevant option for ileus prevention without the risk of impaired sedation. The aim of our study is to assess the efficacy of the administration of naloxegol on the onset of early constipation and early ventilator-acquired pneumonia in brain injured patients receiving opioids for analgosedation.
What Stage of Research Is This?
Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Brain Injuries, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
A target enrollment of 370 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Treatments Being Tested
Naloxegol
Administration of Naloxegol 25 mg per day by nasogastric tube (SNG) or orogastric tube (SOG). The administration should be started within the first 24 hours after the patient is admitted to intensive care and continued for the duration of the administration of the morphine derivative and until 48 hours after its discontinuation.
Placebo
Administration of the placebo according to the same procedures as the experimental arm.

Bring the printable summary of this trial — including the NCT ID (NCT05008926), the sponsor (University Hospital, Brest), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.
Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up?

Who can participate in NCT05008926?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT05008926?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
