Study summary

This study evaluates the effectiveness and safety of infliximab in the treatment of acute pancreatitis in adults. A third of participants will receive one single dose of infliximab via infusion, another third will receive a higher dose of infliximab via infusion and the final third of participants will receive a placebo infusion.

Read the detailed description

Acute pancreatitis (AP) is an inflammatory disorder of the pancreas causing excruciating pain, gastrointestinal dysfunction and pronounced systemic inflammatory responses with circulatory and respiratory disturbances that can lead to organ failure and death.

Tumour necrosis factor alpha (TNFα) has a major role in the pathogenesis and severity of acute pancreatitis. TNFα levels rise early and remain elevated for days in human AP, proportional to severity, presenting a suitable drug target to inhibit the amplified immune responses that further damage the pancreas and drive widespread organ dysfunction.

Infliximab is a chimeric monoclonal antibody biologic drug that blocks the actions of tumor necrosis factor alpha (TNF-α) and is normally used to treat autoimmune diseases. Infliximab has been selected as it is given via intravenous infusion, which will ensure rapid bioavailability to treat AP. This is different from most other biologics, which are given subcutaneously.

This trial will determine the efficacy of early initiation of anti-TNF treatment in AP, setting new standards for trials in AP. Using a randomised, double-blind, placebo-controlled adaptive design, with two doses of a single intravenous infusion of infliximab at 5 mg/kg or 10 mg/kg (the higher dose arm was dropped on 19th May 2026, see Study Design), the trial will determine size of any effect and safety of this treatment.

Terms in these criteria, in plain language(11)

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.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

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.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Of 22 phase 2 interventional studies under Pancreatitis, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 110. This study's planned 91 months is above that.

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 Jul 6, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
