In Table 1 on page 2253 in the 23 November 2017 issue, the sizes of the pegylation moieties of damoctocog alfa pegol and turoctocog alfa pegol are reversed. In the “Mechanism” column, the entry for damoctocog alfa pegol should read, “60-kDa site-specific pegylation,” and the entry for turoctocog alfa pegol should read, “40-kDa site-specific pegylation.” The errors have been corrected in the online version.
