Excerpt

Pegcetacoplan is a small peptide inhibitor of complement that is used to treat adults with paroxysmal nocturnal hemoglobinuria. Serum aminotransferase elevations occur in a proportion of patients treated pegcetacoplan, but episodes of clinically apparent liver injury with jaundice have not been reported with its use.
