The FVC %-predicted represents the adjusted volume of air (adjusted as a percentage of the expected normal valued based on the participant's age, height, gender and ethnicity) that can be forcibly exhaled from the lungs after taking the deepest breath possible. The FVC %-predicted is reduced in patients with interstitial lung disease and is used as a measure of lung involvement and disease severity.

International Working Group (IWG) criteria for hematological improvement was defined as having hemoglobin (Hgb) \<11 g/dL (pretreatment) and an increase in Hgb ≥1.5 g/dL after ≥8 weeks of treatment.

BPAR was defined according to 1997 Banff Criteria as a biopsy Banff grade of IA, IB, IIA, IIB, or III. Grade IA was defined as significant interstitial infiltration with greater than (\>)25% of parenchyma affected, and foci of moderate tubulitis with \>4 mononuclear cells per tubular cross section or group of 10 tubular cells. Grade IB was defined as significant interstitial infiltration with \>25% parenchyma affected, and foci of severe tubulitis with \>10% mononuclear cells per tubular cross section or group of 10 tubular cells. Grade IIA was defined as mild to moderate intimal arteritis. Grade IIB was defined as severe intimal arteritis comprising \>25% of the luminal area. Grade III was defined as transmural arteritis and/or arterial fibrinoid changes and necrosis of medial smooth muscle cells.
