What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing pirfenidone, a medication that may help people with severe lung scarring due to advanced fibrotic sarcoidosis. The drug aims to reduce inflammation and prevent further lung damage, making it easier for patients to breathe. Pirfenidone has been shown to slow the progression of idiopathic pulmonary fibrosis and has potential benefits in other fibrosing interstitial lung diseases.

Will I have to stop taking my current medications?

The trial requires that you stay on a stable dose of prednisone for at least two months before joining, and you should not change other immunosuppressive medications during that time. The protocol does not specify about other medications, so it's best to discuss with the study team.

Is pirfenidone generally safe for humans?

Pirfenidone has been studied for safety in people with idiopathic pulmonary fibrosis (a lung disease) and is generally considered safe, but it can cause side effects. Common side effects include nausea, rash, and fatigue, and managing these can help improve treatment adherence. ^{1 2 3 4 5}

What makes the drug Pirfenidone unique compared to other treatments?

Pirfenidone is unique because it works by reducing fibrosis (scarring) and inflammation in the lungs, which is different from many other treatments that primarily focus on managing symptoms. It is taken orally, which can be more convenient compared to treatments that require injections or infusions. ^{6 7 8 9 10}

What data supports the effectiveness of the drug Pirfenidone?

Research shows that Pirfenidone helps slow down the progression of idiopathic pulmonary fibrosis (IPF), a lung disease, by reducing lung function decline and improving survival rates. It also helps patients maintain their ability to walk longer distances and manage symptoms better over a year. ^{5 11 12 13 14}

Published Research Related to This Trial

In a pooled analysis of data from three phase 3 trials involving 1247 patients with idiopathic pulmonary fibrosis (IPF), pirfenidone significantly reduced the risk of disease progression, showing a 43.8% decrease in patients experiencing a ≥10% decline in lung function or death after one year.

While pirfenidone was effective in slowing disease progression and improving outcomes like walking distance and breathlessness, it was associated with more gastrointestinal and skin-related side effects, although these rarely led to treatment discontinuation.

In a study of 31 patients with acute exacerbation of interstitial pneumonia (AE-IP), the administration of pirfenidone (PFD) did not significantly improve survival rates compared to those not receiving PFD, with survival rates of 78.6% vs 64.7% at 30 days and 64.3% vs 52.9% at 90 days.

However, patients receiving PFD showed a significant reduction in inflammation, as indicated by lower white blood cell counts and C-reactive protein levels, suggesting that PFD may help manage inflammation in AE-IP patients undergoing corticosteroid treatment.

A survey of 169 pulmonologists revealed that gastrointestinal intolerance is a key concern when starting pirfenidone for idiopathic pulmonary fibrosis, leading to the use of alternative titration schedules to help patients reach the full dose.

Strategies to manage side effects included advising patients to take pirfenidone with substantial meals to reduce gastrointestinal issues and recommending sun protection measures to address photosensitivity.

Real-World Practice Patterns for Prevention and Management of Potential Adverse Events with Pirfenidone in Patients with Idiopathic Pulmonary Fibrosis. Wencel, ML., Haselkorn, T., Limb, SL., et al.[2021]

In a meta-analysis of six randomized controlled trials involving 1073 participants, pirfenidone (PFD) was found to have a significantly higher rate of adverse events compared to placebo, leading to more patients discontinuing the treatment.

Common adverse effects associated with PFD included gastrointestinal issues (like nausea and diarrhea), neurological symptoms (such as dizziness and fatigue), and dermatological reactions (including photosensitivity), indicating that while PFD is used for pulmonary fibrosis, it may not be well-tolerated by all patients.

Pirfenidone is an effective treatment for idiopathic pulmonary fibrosis (IPF), shown to reduce lung function decline, decrease mortality, and improve progression-free survival based on randomized controlled trials and real-world studies.

To maximize the benefits of pirfenidone, it is crucial to manage its potential adverse events, and the review outlines strategies for preventing and managing these side effects to enhance patient adherence to the treatment.

A comprehensive safety analysis of pirfenidone, involving 789 patients over a median exposure of 2.6 years, shows that it is generally safe and well tolerated for treating idiopathic pulmonary fibrosis (IPF).

The most common side effects were mild to moderate gastrointestinal and skin-related events, with serious liver enzyme elevations occurring in only 2.7% of patients, indicating a low risk of severe adverse effects.

In a study of 56 myelofibrosis patients treated with ruxolitinib, the presence of multiple gene mutations, particularly high-risk mutations, was associated with shorter treatment duration and progression-free survival, indicating a reduced efficacy of the drug.

Ruxolitinib was less effective in reducing spleen size and improving symptoms in patients with specific mutations (ASXL1, EZH2, SRSF2), highlighting the importance of genetic profiling in predicting treatment outcomes.
