A Phase 1b Study of IV PRM151 in Patients With Idiopathic Pulmonary Fibrosis (IPF)

Idiopathic pulmonary fibrosis (IPF) is a diffuse lung disease with a histological picture of usual interstitial pneumonia and a deteriorating clinical course. The prognosis is poor. Chronic alveolar inflammation with associated parenchymal remodeling is theorized to promote an ongoing abnormal fibrogenic repair response. Corticosteroids and immunomodulatory agents have not been shown to benefit IPF patients. Recently several published clinical studies have indicated a strong correlation between IPF severity and/or disease progression and the levels of specific plasma biomarker proteins related to epithelial cell health and extracellular matrix turnover. PRM-151 is being developed for potential therapeutic uses to prevent, treat, and reduce fibrosis. This study is the first intravenous multiple-dose study in humans, and will be conducted in patients with IPF. Patients will be randomized to receive either PRM-151 or placebo.
