Elevated total bilirubin (at least 2 times the upper limit of normal) was reported in 3.5% of patients; such elevations were seen in 1.2% of patients across phase 2 and 3 trials and were related to glecaprevir-mediated inhibition of bilirubin transporters and metabolism. Bilirubin elevations were asymptomatic, transient, and generally occurred early during therapy; these elevations were mainly indirect and not associated with ALT elevations. No jaundice was observed and total bilirubin levels decreased after completion of therapy.[Ref]
