About haemophilia
As a lifelong inherited bleeding disorder, haemophilia affects about 1 in 10,000 people worldwide. With estimated USD 11 billion in 2024, the global FVIII/FIX market is substantial and grows with a compound annual growth rate (CAGR) of around 1.8%. Haemophilia is one of a number of such disorders that prevent blood from clotting properly. People with haemophilia experience prolonged internal bleeding that can result from a seemingly minor injury. Bleeding into joints and muscles causes severe pain and disability while bleeding into major organs, such as the brain, can cause death.
