Summary
Brief summary
The goal of this clinical trial is to evaluate the impact that ENV-101 has on lung function
and key measures of fibrosis in adult patients with idiopathic pulmonary fibrosis (IPF) and
progressive pulmonary fibrosis (PPF). Another goal of this study is to better understand the
safety and tolerability of ENV-101 in these patient populations.
