Patient Preferences in Treatment of Haemophilia A With and Without Inhibitors: a Discrete Choice Experiment in Germany

June 11, 2026 updated by: Novo Nordisk A/S
This study aims to generate structured patient preference evidence on prophylactic treatment options for haemophilia A for adults with and without inhibitors to support health technology assessment and benefit evaluation processes. The study will examine how individuals with haemophilia A evaluate trade-offs between treatment effectiveness, safety, and treatment administration characteristics when choosing between prophylactic therapies. Participants will repeatedly choose between hypothetical treatment profiles that differ in clinically relevant attributes and levels.
