*3.3. Lung Collagen Content*

Total lung collagen content was significantly reduced by OmeGo and fevipiprant compared to vehicle control: a 4% and 5% reduction, respectively, with low- and high-dose OmeGo (*p* < 0.05) and an 11% reduction with fevipiprant (*p* < 0.01) at study end (Figure 6). No other histopathological assessments of the lung were undertaken.
