Rare diseases Ipsen works on
Each disease page lists every open trial, not only Ipsen's, plus approved treatments.
Acromegaly is a rare hormonal disorder caused by excessive growth hormone production, typically from a pituitary adenoma, resulting in abnormal growth of hands, feet, and facial features.
How common: About 50 to 70 people per million, according to NORD, with 3 to 11 new cases per million people each year
Acute myeloid leukemia (AML) is a fast-growing cancer of the bone marrow in which immature white blood cells called blasts crowd out normal blood cells, causing fatigue, infections and bleeding...
How common: The National Cancer Institute's SEER program estimates 22,720 new US cases and 11,500 deaths in 2026, about 1.1% of new cancers, and 83,311 people were living with AML in 2023
Alagille syndrome is a rare autosomal dominant disorder affecting the liver, heart, skeleton, face, and eyes.
How common: 1 in 30,000 to 43,000 people
Fibrodysplasia Ossificans Progressiva
Fibrodysplasia Ossificans Progressiva (FOP) is an extremely rare genetic disorder characterized by progressive heterotopic ossification, where soft tissues (muscles, tendons, ligaments) gradually...
How common: Extremely rare, about 1 in 1 million to 1 in 2 million people worldwide
Neuroendocrine tumors (NETs) grow from hormone-making cells, most often in the small intestine, pancreas, rectum or lungs.
How common: About 244,000 people in the US were living with a neuroendocrine neoplasm, the wider group that includes NETs, in 2021, with about 8.5 new diagnoses per 100,000 people a year (Dasari et al., JAMA Network Open 2025); an earlier estimate for NETs alone was about 171,000 in 2014 (JAMA Oncology 2017)
Paragangliomas are rare neuroendocrine tumors arising from chromaffin tissue outside the adrenal medulla.
How common: 1 in 300,000 to 1,000,000; ~30% are hereditary
Pheochromocytoma is a rare neuroendocrine tumor arising from chromaffin cells of the adrenal medulla that produces excessive catecholamines (epinephrine and norepinephrine).
How common: About 2 to 8 new cases per million people a year (National Cancer Institute)
Primary Biliary Cholangitis (PBC) is a chronic autoimmune liver disease in which the immune system mistakenly attacks the small bile ducts in the liver, leading to bile duct destruction and...
How common: About 14.6 per 100,000 people worldwide in a 2021 pooled analysis of 47 population studies, highest in North America (21.8 per 100,000) and lowest in the Asia-Pacific region (9.8 per 100,000)
