Trial summary

Post-ERCP pancreatitis (PEP) is the most common complication after ERCP, which was associated with occasional mortality, prolonged hospital days and increased health costs. Some studies investigated the effectiveness of different Nonsteroidal antiinflammatory drugs (NSAIDs) for prevent PEP. Read more about this study

About this study

Official title: Rectal Disclofenac Versus Indomethacin for Prevention of Post-ERCP Pancreatitis (DIPPP): A Multicentre, Double-blind, Randomised, Controlled Trial

Post-ERCP pancreatitis (PEP) is the most common complication after ERCP, which was associated with occasional mortality, prolonged hospital days and increased health costs. Some studies investigated the effectiveness of different Nonsteroidal antiinflammatory drugs (NSAIDs) for prevent PEP. However, several high-quality RCTs and meta-analyses consistently demonstrated only100mg rectal indomethacin or diclofenac significantly reduced PEP incidence compared with placebos. Thus, European Society of Gastrointestinal Endoscopy, American Society for Gastrointestinal Endoscopy and Japanese Society of Hepato-Biliary-Pancreatic surgery guidelines recommended rountine administration of 100mg rectal indomethacin or diclofenac in unselected patients who underwent ERCP.

Up to date, the mechanisms of NSAIDs in preventing pancreatitis were not fully elucidated. Diclofenac and Indomethacin showed similar inhibitory effects in phospholipase A2 and cyclooxygenase pathways. And the peak concentration of diclofenac and indomethacin both occurs between 30 and 90 min after rectal administration. However, diclofenac may be a stronger inhibitor of other pancreatitis-related imflammatory siginals (e.g. nuclear factor kappa-B) than indomethacin. Recently, several meta-analyses found 100mg rectal diclofenac to be more efficacious than 100mg rectal indomethacin. Despite these data, there is no conclusive evidence to prove that rectal diclofenac could provide incremental benefits over indomethacin from high-quality randomized, controlled trials. Therefore, the investigators conducted a multicenter, double-blind, randomized, controlled clinical trial to evaluate the efficacy of rectal diclofenac versus indomethacin for the prevention of post-ERCP pancreatitis in average-risk patients.

Being tested
100mg diclofenac, 100mg indomethacin

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of post-ERCP Pancreatitis

    The diagnosis of post-ERCP pancreatitis was confirmed if there was new onset of upper abdominal pain associated with an increased amylase or lipase level of at least 3 times the upper limit of normal range at 24 hours after ERCP, accompanied with extension of hospitalization for at least 2 nights.

    Measured: 30 days

Secondary outcomes (4)
  1. Rate of moderate or severe PEP

    The severity classification of post-ERCP pancreatitis was defined according to the Cotton Criteria. Mild PEP: with an extension of hospitalization period of 2-3 days; Moderate PEP: with an extension of hospitalization period of 4-10 days; Severe PEP: with an extension of more than 10 days, or hemorrhagic pancreatitis, phlegmon, or pseudocyst, intervention (percutaneous drainage or surgery), or death.

    Measured: 30 days

  2. Rate of Overall ERCP-related complications

    ERCP-related complications include post-ERCP pancreatitis, gastrointestinal bleeding, perforation or infection according to Cotton Criteria.

    Measured: 30 days

  3. Rate of patients with different severity of pancreatitis evaluated by revised Atlanta criteria

    Measured: 30 days

  4. Rate of NSAIDs-related complications

    NSAIDs-related complications include: acute kidney injury, allergic reaction, gastrointestinal bleeding, myocardial infarction, cerebrovascular accident, and death

    Measured: 30 days

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted17 Jul 2023
  2. Study start1 Jun 2023
  3. Primary completion22 Jun 2024
  4. Study completion22 Jun 2024

Why it stopped: The data from the interim analysis showed a opposite trend predicting possible of benefit of indomethacin and conditional power analysis revealed a low probability of confirming the benefit of diclofenac if this trial will be continued.
