Off-label use of bevacizumab for wet age-related macular degeneration in Europe

Purpose To analyse current off-label use of bevacizumab for wet age-related macular degeneration (AMD) in Europe. Methods The study was conducted as a combined survey and literature review. It included the 22 most populous countries in Europe. In each country, ophthalmologists with particular knowledge about off-label treatment responded to a questionnaire. Results Answers were obtained from twenty European countries. The off-label use of bevacizumab for wet AMD greatly differed between nations; the bevacizumab proportion varied from non-existent (0%) to very high (97%). There were also large disparities within single countries (e.g. 0-80%), which were attributable to differences in regional decision-making. Both governmental institutions and national ophthalmological societies expressed highly diverging opinions on the use of off-label treatment. Intravitreal administration of bevacizumab had been a matter of legal dispute in several countries. The question about responsibility for off-label therapy mainly remained unanswered. Conclusions There was a highly varying utilization of bevacizumab between European countries. Despite an intention of a consistent approach to medical regulations, Europe has not yet reached a professional or political consensus on the ophthalmic off-label use of bevacizumab.
