What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing pirfenidone, a medication already used for lung disease, to see if it can help patients with severe acute pancreatitis. The goal is to find out if it is safe and if it can reduce inflammation and improve symptoms. Patients will be monitored closely throughout the study.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it excludes those on immunosuppressive medications and certain drugs like fluvoxamine or sildenafil. It's best to discuss your specific medications with the trial team.

Is pirfenidone safe for humans?

Pirfenidone is generally considered safe for humans as it is FDA approved for treating idiopathic pulmonary fibrosis (a lung disease). Studies in mice suggest it may also help with pancreatitis by reducing inflammation and fibrosis (scarring), but more research is needed to confirm its safety and effectiveness for this condition in humans. ^{1 2 3 4 5}

How does the drug pirfenidone differ from other treatments for acute pancreatitis?

Pirfenidone is unique because it is an anti-inflammatory and anti-fibrotic drug that increases IL-10, a protein that helps reduce inflammation, and is already FDA approved for another condition, idiopathic pulmonary fibrosis. Unlike other treatments, it can be administered even at the peak of injury to reduce the severity of acute pancreatitis by modulating immune responses and decreasing inflammatory cytokines. ^{2 4 6 7 8}

What data supports the effectiveness of the drug Pirfenidone for treating acute pancreatitis?

Research in mice shows that Pirfenidone, a drug approved for lung disease, can reduce inflammation and injury in acute pancreatitis by increasing IL-10, a helpful immune molecule, and changing how immune cells behave. ^{2 4 5 6 9}

Are You a Good Fit for This Trial?

Published Research Related to This Trial

Pirfenidone, an FDA-approved drug for idiopathic pulmonary fibrosis, shows promise in reducing the severity of acute pancreatitis (AP) by decreasing local and systemic injury and inflammation, even when administered at the peak of injury.

The drug works by increasing IL-10 secretion from macrophages and modulating the immune response, as confirmed by experiments that demonstrated its efficacy relies on the presence of IL-10 and macrophages.

Pirfenidone increases IL-10 and improves acute pancreatitis in multiple clinically relevant murine models. Palathingal Bava, E., George, J., Tarique, M., et al.[2022]

Pirfenidone, an FDA-approved drug for Idiopathic Pulmonary Fibrosis, has shown promising results in mouse models of chronic pancreatitis (CP) by reducing fibrosis, inflammation, and pancreatic damage, indicating its potential as a new treatment option for CP.

The drug's efficacy appears to be linked to its ability to reduce macrophage infiltration and alter cytokine levels in the pancreas, suggesting that targeting macrophages may be a key mechanism in its therapeutic action.

New drugs like somatostatin, octreotide, and loxiglumide have been tested to reduce pancreatic secretion in severe acute pancreatitis, but the mortality rate remains high despite these efforts.

The anti-inflammatory agent IS-741 has shown promise in experimental models of pancreatitis, indicating potential for future clinical applications in managing this condition.

Acute pancreatitis in rats leads to increased pulmonary vascular permeability, indicating that lung injury is a significant complication of this condition.

The administration of lexipafant (BB-882), a platelet-activating factor antagonist, significantly reduced lung injury in the pancreatitis model, suggesting its potential as a therapeutic option for managing complications associated with acute pancreatitis.

In a randomized controlled trial involving 83 patients with acute pancreatitis, pentoxifylline did not show any significant benefit over placebo in reducing severe outcomes such as death or organ failure.

Patients receiving pentoxifylline experienced longer hospital stays and higher readmission rates compared to those on placebo, suggesting that pentoxifylline may not be an effective treatment for acute pancreatitis.

Data from the FDA Adverse Event Reporting System suggest that incretin-based therapies, like GLP-1 receptor agonists and DPP-4 inhibitors, may increase the risk of acute pancreatitis and pancreatic cancer.

However, population-based observational studies do not support these findings, indicating that current evidence is conflicting and insufficient to determine the true risk associated with these diabetes treatments.

In a study involving liraglutide users followed for a median of 15 months, the incidence rate of acute pancreatitis was slightly higher (187.5 cases per 100,000 person-years) compared to other non-GLP-1 therapies, but this difference was not statistically significant (adjusted RR 1.10).

For pancreatic cancer, liraglutide showed a lower incidence rate (19.9 cases per 100,000 person-years) compared to non-GLP-1 therapies (33.0 cases), suggesting no increased risk associated with liraglutide (adjusted RR 0.65).

In a study of 15 adult patients with pancreas sufficient cystic fibrosis (PS-CF) and a history of acute pancreatitis (AP), the use of CFTR modulators significantly reduced the risk of recurrent AP over an average follow-up of 36.7 months.

None of the patients who continued on CFTR modulators experienced further episodes of AP or required hospitalization for AP-related issues, suggesting that enhancing CFTR function may help protect against pancreatitis in these patients.

Captopril, an angiotensin-converting enzyme inhibitor, significantly reduced serum amylase levels, myeloperoxidase activity, and histopathological damage in rats with acute edematous pancreatitis, indicating its potential as a therapeutic option.

In severe necrotizing pancreatitis, captopril also improved pancreatic tissue damage, while losartan showed some benefits in reducing necrosis and inflammation, but L-158809 did not demonstrate similar protective effects.
