1 April 2016 - Efmoroctocog alfa (trade name: Elocta) has been approved since November 2015 for people with type A haemophilia. This is an inherited disorder that impairs blood clotting. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether this new drug offers an added benefit over the appropriate comparator therapy both in prevention and in on-demand treatment. Such an added benefit cannot be derived from the dossier, however, because it contained no study data adequate for the research question.

According to the Federal Joint Committee (G-BA), the new drug was to be compared with a recombinant or human plasma-derived coagulation factor VIII drug as appropriate comparator therapy. The drug manufacturer presented no data for such a direct comparison, however.

Instead, the dossier contained an unadjusted historical comparison on prophylactic treatment only. Data from a study on efmoroctocog alfa were compared with data from seven studies on the comparator therapy. A simplified search conducted by IQWiG showed that the study pool was incomplete. This was caused by an erroneous and incomplete search by the manufacturer for studies on the comparator therapy; no search at all was conducted in trial registries.
