The global aHUS treatment market was valued at approximately US$ 1,431 million in 2023 and is expected to reach US$ 2,308.84 million by 2033, growing at a CAGR of about 4.9% during the forecast period 2023 to 2033.

aHUS is a rare, life-threatening disorder characterized by abnormal blood-clot formation in small-vessel microvasculature leading to hemolytic anemia, low platelets, and kidney injury. Treatment often involves complement-inhibitors, plasma-exchange, supportive care and emerging gene therapies.
