“…In a randomised, double-blind, single ascending dose study in healthy volunteers (N ¼ 26), single doses of PRM-151 up to 20 mg/kg were well tolerated, with no dose-limiting adverse events [66]. When a single dose of PRM-151 (10 mg/kg) was administered to 3 patients with IPF, elevated IL-6 levels were reduced, as were circulating fibrocytes [66]. In a Phase I randomised, double-blind, placebocontrolled ascending dose study in patients with IPF (N ¼ 21), PRM-151 given on days 1, 3, 5, 8 and 15 was generally well tolerated [71].…”
