Treatment response was assessed by changes in extent of parenchymal disease (HRCT and FVC).Results: 54 subjects (males 83%, mean age 67 years, median FVC % predicted 63.2%) were enrolled. Quantified HRCT scores of whole lung fibrosis (QLF) and all abnormal interstitial lung disease (QILD) at week 24 showed decreases from baseline greater than analytical variability (±2%) in 6 (24%) and 8 (32%) of 25 subjects, respectively. Changes in both QLF and QILD score were significantly correlated with changes in FVC % predicted (for QILD, r=-0.55, p=0.004). Mean decreases in FVC % predicted were less than in historical controls. Safety findings to date include 13 SAEs (none drug-related), 1 acute exacerbation, 9 respiratory-related hospitalizations, and 3 deaths (all related to IPF).Conclusions: FG-3019, a novel anti-fibrotic agent, is well tolerated by subjects with IPF. No drug-related SAEs have been reported to date. Promising results of measurement of quantified lung fibrosis scores and FVC warrant pursuing the clinical trial with a higher dose of FG-3019 to further assess safety and efficacy in subjects with IPF.
