In a recent publication in the <i>European Journal of Hematology</i>, researchers studied the effectiveness and safety of damoctocog alfa pegol in a normal clinical setting (HEM-POWR).

Unfavorable treatment reactions (adverse events) were also recorded; these describe how safe the treatment is. The HEM-POWR study found that people had fewer bleeds, including joint bleeds, on damoctocog alfa pegol compared to previous treatments. No new adverse events were reported.
