What is the mechanism of action of this treatment?

The most common treatments for Idiopathic Pulmonary Fibrosis (IPF) include antifibrotic agents like nintedanib and pirfenidone, which work by slowing the progression of fibrosis in the lungs. Nintedanib inhibits multiple tyrosine kinases involved in the signaling pathways that lead to fibrosis, while pirfenidone reduces fibroblast proliferation and the production of fibrotic mediators. These mechanisms are crucial for IPF patients as they help to preserve lung function and improve quality of life. Additionally, immune checkpoint inhibitors like atezolizumab, which block the PD-L1 pathway to enhance the immune system's ability to fight disease, are being studied for their potential to treat IPF by modulating the immune response involved in fibrosis.

What side effects are associated with this type of intervention?

Common treatments for Idiopathic Pulmonary Fibrosis (IPF) include antifibrotic agents like pirfenidone and nintedanib. Pirfenidone can cause side effects such as nausea, rash, and liver function abnormalities, while nintedanib may lead to diarrhea, liver enzyme elevation, and gastrointestinal issues. Immune checkpoint inhibitors like atezolizumab, which are being studied for IPF, can cause immune-related adverse events including pneumonitis, rash, and colitis. These treatments aim to manage symptoms and slow disease progression, but they come with a risk of significant side effects that require careful monitoring.

What prior FDA approvals exist?

The FDA has approved two main drugs for the treatment of Idiopathic Pulmonary Fibrosis (IPF): pirfenidone and nintedanib. These drugs are antifibrotic agents that help slow disease progression. While atezolizumab, an immune checkpoint inhibitor, is being studied for its safety and efficacy in IPF, it is not yet approved for this indication. Immune checkpoint inhibitors like atezolizumab are primarily used in cancer treatment, and their role in IPF is still under investigation.

What other types of research exist?

Promising alternatives to Atezolizumab for IPF patients include: 1) Pirfenidone, which has shown benefits in unclassifiable interstitial lung disease and interstitial pneumonia with autoimmune features. 2) Pamrevlumab, an anti-connective tissue growth factor therapy, which has shown promise in clinical trials for IPF. 3) Nintedanib, approved for progressive fibrosing ILD, which may also be beneficial for IPF.

Study Summary

This trial will test the safety and preliminary effectiveness of a new cancer drug in patients with IPF, a lung condition.

Who is the study for?

This trial is for men and women over 50 with a confirmed diagnosis of idiopathic pulmonary fibrosis (IPF), as shown by specific patterns on high-resolution CT scans or lung biopsy. Participants must not have used certain IPF treatments recently, be free from significant other diseases, and agree to contraception if applicable. They cannot join if they've had recent vaccinations, blood clots, severe allergies to similar drugs, or are smokers.Check my eligibility

What is being tested?

The study tests the safety and initial effectiveness of Atezolizumab—an immune checkpoint inhibitor already approved for cancer treatment—in patients with IPF. It aims to see how well this drug can work in a different disease by possibly using the body's own immune system to slow down fibrosis.See study design

What are the potential side effects?

Atezolizumab may cause side effects like inflammation in various organs including liver and intestines, hormonal imbalances, skin reactions, increased risk of infections due to weakened immunity, potential infusion-related reactions during administration of the drug.
