About TransCon PTH1

About hypoparathyroidism (HP) 2,3,4,5,6,7

Hypoparathyroidism (HP) is a rare endocrine disease characterized by insufficient levels of parathyroid hormone (PTH), resulting in low calcium content and elevated phosphate levels in the blood. HP affects approximately 200,000 patients in the United States, Europe, Japan and South Korea, the majority of whom develop the disease as a result of damage or accidental removal of the parathyroid glands during thyroid surgery. Patients often have a reduced quality of life. Short-term symptoms include weakness, severe muscle cramps (tetany), abnormal sensations such as tingling, burning and numbness (paresthesia), memory loss, poor judgment and headache. In the long term, this complex disorder can increase the risk of major complications, such as extra-skeletal calcium deposits occurring in the brain, lens, and kidneys, which can lead to impaired kidney function.

HP remains among the rare states of hormonal insufficiency without replacement therapy that restores the missing hormone to physiological levels. Standard care with active vitamin D analogues and calcium supplementation does not fully control the disease and may contribute to the risk of kidney disease. As a result, patients with HP have an estimated 4 to 8 times higher risk of kidney disease compared to healthy controls.
