Summary

This trial tests a new drug for treating idiopathic pulmonary fibrosis (IPF). It aims to block a protein that causes lung scarring, seeking a safer and more effective treatment for this severe lung disease. Originally developed for cancer, this drug is now being explored for its potential to treat IPF by blocking proteins involved in lung scarring.

Who is the study for?
This trial is for men and women over 40 with idiopathic pulmonary fibrosis (IPF), confirmed by specific guidelines. Participants must have a certain lung function level, not be current smokers, and able to perform pulmonary tests. Men should use contraception or be sterile; women must be nonchildbearing or also use contraception.
What is being tested?
The study is testing saracatinib, a drug initially developed for cancer treatment, against a placebo to see if it's safe and effective for IPF patients. It will also look at how the body processes the drug and search for biomarkers related to lung scarring.
What are the potential side effects?
While specific side effects of saracatinib in IPF are being studied, potential risks may include typical reactions seen in other treatments like digestive issues, liver enzyme changes, fatigue, skin reactions or increased risk of infections.

Other Research
The most common treatments for Idiopathic Pulmonary Fibrosis (IPF) are nintedanib and pirfenidone. Nintedanib is a tyrosine kinase inhibitor that targets multiple growth factor receptors involved in the fibrotic process, thereby slowing disease progression by inhibiting pathways that lead to fibrosis. Pirfenidone works by reducing fibroblast proliferation, cytokine production, and collagen synthesis, which collectively help to slow the progression of lung scarring. Saracatinib, an investigational Src kinase inhibitor, aims to block specific signaling pathways involved in fibrosis. These treatments are crucial for IPF patients as they help to slow the decline in lung function, potentially improving quality of life and extending survival.
