• TransCon PTH could, if approved, become the first hormone replacement therapy to address the underlying cause of hypoparathyroidism, an area of major unmet medical need for the estimated 70,000-90,000 adults living with chronic disease in the United States alone.
• European MAA on track for Q4 2022 submission
COPENHAGEN, Denmark I August 31, 2022 I Ascendis Pharma A/S (Nasdaq: ASND) today announced it has submitted a New Drug Application (NDA) to the U.S. Food & Drug Administration (FDA) for TransCon PTH, an investigational prodrug designed to restore parathyroid hormone (PTH [1-34]) to physiological levels over 24 hours in adult patients with hypoparathyroidism. TransCon PTH has been granted Orphan designation in the United States and European Union.
“We believe the best way to treat hypoparathyroidism is to replace the missing endogenous hormone at stable, physiological levels 24 hours a day. Accordingly, our data support that TransCon PTH, if approved, could become the first-in-class therapy to address the underlying cause of disease and address the urgent needs of patients in the U.S., who today have no such treatment options available,” said Dana Pizzuti, Ascendis Pharma’s Senior Vice President and Chief Medical Officer. “Our Phase 2 and Phase 3 trials were the first ever in which most treated patients (86% and 79%, respectively; at 6 months of treatment) achieved normalization of serum calcium and independence from conventional therapy. Further underscoring the potential benefits of our TransCon PTH product candidate, treated patients reported significant reductions in disease-specific physical and cognitive symptoms and significant improvements in their quality of life.”
The NDA is based on data from the global Phase 3 PaTHway Trial and the Phase 2 PaTH Forward Trial, as well as data from the Company’s ongoing open-label extension studies for both trials. Notably, 57 out of 59 patients continue in the open-label portion of the Phase 2 trial beyond two years of treatment, and 78 out of 79 patients continue in the open-label portion of the Phase 3 trial of TransCon PTH. In these studies, TransCon PTH has been generally well tolerated, with no discontinuations related to study drug.
In the fourth quarter of this year, Ascendis Pharma plans to submit a Marketing Authorisation Application (MAA) for TransCon PTH in hypoparathyroidism to the European Medicines Agency and expects to announce topline results for Pathway Japan, the Phase 3 trial of TransCon PTH in Japan. A phase 3 trial of TransCon PTH in hypoparathyroidism is ongoing in Greater China through VISEN Pharmaceuticals.
About TransCon™ Technology
TransCon refers to “transient conjugation.” Ascendis Pharma’s proprietary TransCon platform is an innovative technology designed to create new therapies that optimize therapeutic effect, including efficacy, safety and dosing frequency. TransCon molecules have three components: an unmodified parent drug, an inert carrier that protects it, and a linker that temporarily binds the two. When bound, the carrier inactivates and shields the parent drug from clearance. When injected into the body, physiologic conditions (e.g., pH and temperature) initiate the release of the active unmodified parent drug, in a predictable manner and at predictable levels. TransCon technology is designed to be applied broadly to a protein, peptide or small molecule in multiple therapeutic areas, and to be used systemically or locally.
About Hypoparathyroidism 1, 2, 3, 4, 5, 6
Hypoparathyroidism is a rare endocrine disorder characterized by insufficient levels of parathyroid hormone (PTH), resulting in low calcium and elevated phosphate levels in the blood. Hypoparathyroidism affects approximately 200,000 patients in the United States, Europe, and Japan, most of whom develop the condition following damage to or accidental removal of the parathyroid glands during thyroid surgery. Conventional treatment with calcium supplements and active vitamin D (also called calcitriol) does not effectively address the short-term symptoms, long-term complications, or quality-of-life impacts of hypoparathyroidism.
Short-term symptoms include weakness, severe muscle cramps (tetany), abnormal sensations such as tingling, burning and numbness (paresthesia), memory loss, impaired judgment, and headache. Patients often experience decreased quality of life, and, over the long term, this complex disorder can increase risk of major complications, such as calcium deposits in the brain, blood vessels, eye, and other soft tissues – including the kidneys, which can lead to impaired renal function.
Hypoparathyroidism remains among the few hormonal insufficiency states without a replacement therapy that restores the missing hormone at physiologic levels. Current standard of care with high doses of calcium and active vitamin D does not fully control the disease or address its underlying cause and may contribute to risk of renal disease. Patients with hypoparathyroidism have an estimated 4- to 8-fold greater risk of renal disease compared to healthy populations. Hypoparathyroidism is also associated with a 2-fold increased risk of depression or bipolar disorder compared to healthy populations.
