Imaging Evaluation of PLN-74809 in Participants With IPF (PLN-74809)
Purpose
This is a Phase 2a, single -center, randomized, double-blind, placebo-controlled study to evaluate type 1 collagen deposition in the lungs following once-daily treatment with PLN-74809 for 12-weeks. This study is occurring at Massachusetts General Hospital.

Detailed Description
This is a Phase 2a, single-center, randomized, double-blinded, placebo-controlled study to evaluate type 1 collagen deposition in the lungs of participants with Idiopathic Pulmonary Fibrosis (IPF) following once-daily (QD) treatment with 160 mg PLN-74809 for 12 weeks. The study consists of an up to 28-day screening period, a 12-week treatment period, and a 2 week (±3 days) post treatment follow-up period. Approximately 12 eligible participants will be randomized in a 2:1 ratio (160 mg PLN-74809 vs placebo; approximately 8 receiving PLN-74809 and 4 receiving placebo) on Day 1 (Visit 3). Randomization will be stratified by use of standard of care IPF therapy with pirfenidone or nintedanib. PET/MRI scans will be conducted at Baseline and at Week 12.
