Rectal Indomethacin in the Prevention of Post-ERCP Pancreatitis

June 24, 2019 updated by: Evan Fogel, Indiana University

Rectal Indomethacin in the Prevention of Post-ERCP Pancreatitis in High Risk Patients: Searching for the Optimal Dose. A Prospective, Randomized Trial

It is now established that indomethacin, a non-steroidal anti-inflammatory drug, at a dose of 100 mg, is effective in reducing the frequency and severity of pancreatitis (inflammation of the pancreas) after endoscopic retrograde cholangiopancreatography (ERCP) in high risk patients. However, the optimal dose required is not known. The purpose of this study is to determine whether a dose of 200 mg, administered as rectal suppositories, is more effective than the standard dose of 100 mg. An ERCP procedure is a scope procedure where a lighted tube with a camera is passed down the patient's throat and allows for evaluation of the bile duct and/or pancreatic duct. The most common side effect of this procedure is post-ERCP pancreatitis, or swelling of the pancreas. Some patients are at higher risk for this complication than others. Our hypothesis is to compare the efficacy of these two dose regimens (100 mg vs 200 mg) of prophylactic rectally-administered indomethacin on the frequency and severity of post-ERCP pancreatitis in high-risk patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

After obtaining informed consent, subjects will undergo ERCP per clinical protocol. All procedure-related clinical decisions and interventions will be dictated by the performing physician as he or she sees fit. At the end of the procedure, it will be determined by the endoscopist and research coordinator whether the patient meets inclusion criteria. If inclusion criteria are met, subjects will be randomized by concealed allocation to receive either 100mg or 150mg indomethacin, in the form of two or three 50mg rectal suppositories. Those patients who are randomized to receive the 100mg dose will receive an additional glycerin suppository. Four hours later, those patients who were randomized to the high-dose group will then receive an additional 50mg suppository while in the recovery area. At this same time point, subjects who were randomized to the standard-dose group, will receive a glycerin suppository in the recovery area. All participating patients will receive a total of 4 suppositories.

Phase

Phase

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants Who Developed Post-ERCP Pancreatitis
Time Frame: 5 days
Assessment of whether patients developed post-ERCP pancreatitis, defined as a new onset of pain (or worsening of existing pain) in the upper abdomen, an elevation in pancreatic enzymes of at least three times the upper limit of the normal range 24 hours after the procedure, and hospitalization for at least two nights.
5 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Moderate or Severe Post-ERCP Pancreatitis
Time Frame: 30 days
Assessment of whether patients developed either moderate or severe post-ERCP pancreatitis, defined according to established consensus criteria (Cotton et al., Gastrointestinal Endoscopy 1991;37:383-93). Severity of post-ERCP pancreatitis is partly defined according to length of stay. Moderate pancreatitis is defined as a 4-10 day hospitalization. Severe post-ERCP pancreatitis is defined as a hospitalization of greater than 10 days post-ERCP, or development of a complication (eg. pseudocyst or necrosis), or need for intervention (drainage or surgery).
