Expanded Access Program of Palopegteriparatide in Patients With Hypoparathyroidism

N/AApproved For MarketingNCT05654701

Ascendis Pharma Bone Diseases A/S

Overview

To provide palopegteriparatide (TransCon PTH), an investigational parathyroid hormone (PTH) replacement therapy in an expanded access setting for adult patients with hypoparathyroidism who have previously received PTH-treatment, who meet the eligibility criteria for this protocol as described below and have a clear unmet medical need that cannot be adequately treated by a commercial product or a clinical trial.

This is an expanded access program for eligible participants who previously received PTH treatment and who are ineligible for an ongoing TransCon PTH clinical trial. The treating physician/investigator contacts Ascendis Pharma when, based on their medical opinion, a patient meets the criteria for inclusion in the expanded access program. Participants will start with a fixed dose of study drug and will be individually and progressively titrated to an optimal dose based on serum calcium levels, followed by an individualized dosing period until palopegteriparatide is commercially available to the participant. For patients taking conventional therapy with calcium and or active forms of vitamin D, these therapies will be reduced in dose and/or discontinued during titration of palopegteriparatide.
