Polyethylene Glycol Versus Lactulose on Hepatic Encephalopathy in Patients With Cirrhosis;(PEGHE Trial)
A Phase 4 study testing Polyethylene Glycols and Lactulose in people with Hepatic Encephalopathy, run by Aga Khan University at 1 site in Pakistan.
Trial summary
Hepatic Encephaopathy is a common complication occurring in patients with Liver cirrhosis. Patients usually develop mild confusion, sleep disturbance or obtundation. It occurs due to accumulation of excess ammonia in the brain, as the liver is unable to metabolize the ammonia. Read more about this study

About this study
Official title: Effect of Polyethylene Glycol Versus Lactulose on Hepatic Encephalopathy in Patients With Liver Cirrhosis; a Randomized Clinical Trial (PEGHE Trial)
Hepatic Encephaopathy is a common complication occurring in patients with Liver cirrhosis. Patients usually develop mild confusion, sleep disturbance or obtundation. It occurs due to accumulation of excess ammonia in the brain, as the liver is unable to metabolize the ammonia. The common gold standard treatment recommended for patients with Hepatic Encephalopathy is Lactulose syrup. This is a non absorbable sugar, often combined with an antibiotic called Rifaxamine to treat this condition.
Polyethylene glycol is in a class of medications called osmotic laxatives which works by causing water to be retained with the stool. PEG and lactulose, when used together, result in faster resolution of symptoms suggesting that PEG may be superior to standard lactulose therapy in these patients.

Non-absorbable sugars like lactulose are associated with non-serious (mainly gastrointestinal) adverse events like diarrhea and bloating Hence, due to the side effect profile, newer drugs continue to be tested for treatment of Hepatic Encephalopathy.
The aim of this research project is to compare the effect of PEG versus lactulose for treatment of HE in patients with liver cirrhosis. The investigators want to compare the resolution of HE as the main outcome. In addition, they will compare length of stay, non-serious (mainly gastrointestinal) adverse events, and 3 months outcome. The investigators hypothesize that rapid purgation of the gut using PEG may resolve HE more effectively than lactulose.
Read the detailed description
Hepatic encephalopathy (HE) is a common neuropsychiatric complication of liver cirrhosis manifested by mild confusion, sleep disturbance or obtundation. Lactulose treatment has long been the standard of care, which presumably acidifies stool and eradicates toxic metabolites. However a third of these patients with hepatic encephalopathy do not respond to this standard treatment and have refractory HE. Hence newer drugs with effective improvement in HE and better side effect profile are still being tested.
Polyethylene glycol (PEG) is in a class of medications called osmotic laxatives which works by causing water to be retained with the stool. PEG and lactulose, when used together, result in rapid overt HE resolution within 24 hours compared to the standard-of-care lactulose, suggesting that PEG may be superior to standard lactulose therapy in patients with cirrhosis hospitalized for acute HE.
Rationale Non-absorbable disaccharides like lactulose are associated with non-serious (mainly gastrointestinal) adverse events like diarrhea and bloating, hence, due to the side effect profile, newer drugs continue to be tested for treatment of HE.
Hypothesis and Aim The aim of this research project is to compare the effect of PEG with Lactulose for treatment of Hepatic Encephalopathy in patients with liver cirrhosis. The investigators want to compare the resolution of HE as the main outcome. In addition, they would compare length of stay, non-serious (mainly gastrointestinal) adverse events, and 3 months outcome. The investigators hypothesize that rapid purgation of the gut using PEG may resolve HE more effectively than lactulose.
These aims are original in that the investigators aim to test this hypothesis on a different patient population (South Asian), where the predominant cause of cirrhosis is due to viral hepatitis C and B. In addition,the investigators will also look at the effect of PEG v lactulose on 3 months outcome in this study.
Significance The significance of this proposal is that if the investigators can prove the hypothesis, it will add to the currently limited evidence on use of PEG in treatment of HE in the world. PEG might have a better side effect profile when compared to lactulose. Based on current market pricing of lactulose, if PEG is found to have favorable outcome then it might be more cost effective as well. Hence PEG might be a useful alternative in 30% of those who don't respond to lactulose, if PEG shows favorable outcome.
Objective Primary: To determine the effect of PEG versus Lactulose on resolution of HE in patients with liver cirrhosis during inpatient stay at 24 hours, 48 hours and 72 hours .
Secondary: To determine the effect of Lactulose versus PEG on length of stay, and 3 months outcome in patients with liver cirrhosis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Polyethylene GlycolsDrug
Polyethylene glycol will be administered to half of the study patients, and their response recorded and compared with that of the Lactulose arm.
LactuloseDrug
Lactulose (standard of care) will be administered to half of the study patients and their response recorded.
| Study group | Role | What they receive |
|---|---|---|
| Lactulose | Active comparator | 90 ml of Lactulose dissolved in 750 ml of water administered orally by mouth or nasogastric tube (three doses within 24 hrs) continued up to 72 hours or until patient discharge, whichever comes first. Receives: Drug: Lactulose |
| PEG: Polyethylene Glycol | Experimental | Three or four sachet of Movicol(PEG) will be dissolved in 750 ml of water and will be given over 24 hrs as 3 doses orally by mouth or Nasogastric tube and will continue up to 72 hours or until patient discharge, whichever comes first Receives: Drug: Polyethylene Glycols |
What is being measured
The primary outcome is the main question the study is designed to answer.
Resolution of Hepatic Encephalopathy
Calculated using Hepatic Encephalopathy scoring Algorithm (HESA). Resolution is defined as reduction of at least 1 grade of HESA score after 24 hours, 48 hours and if applicable 72 hours of therapy during hospital stay
Measured: Change in HESA score at 24 hours, 48 hours and if applicable, 72 hours of drug administration
Secondary outcomes (2)
Mean Length of inpatient stay in hours
Duration of hospital stay will be recorded in hours
Measured: at time of patient discharge, an average of 72 hours
3 months outcome (readmission with Hepatic Encephalopathy)
Patient will be asked at 3 month follow up if there was any other readmission anywhere with Hepatic Encephalopathy
Measured: The three month outcome will be assessed at clinic follow-up at 3 month or by phone call if patient is lost to follow up

The record says: status not confirmed, as of the sponsor's last update on 19 Apr 2023. 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 Pakistan. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Om Parkash (+923333509749, om.parkash@aku.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Resolution of Hepatic Encephalopathy (time frame: Change in HESA score at 24 hours, 48 hours and if applicable, 72 hours of drug administration). 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 NCT04436601, which also lists 24 linked publications.
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 19 Apr 2023.
