In Table 1 on page 1091, the heading for column 2 should read “Cohort 1 (50 IU/kg efanesoctocog alfa)” and the heading for column 3 should read “Cohort 2 (65 IU/kg efanesoctocog alfa).

The same corrections apply to the headings in Table 2 on page 1093.

The errors have been corrected in the published article.
