Parathyroid Allotransplantation in Medically Refractory Hypoparathyroidism
Parathyroid Allotransplantation in Medically Refractory Hypoparathyroidism

NCT05114980

WithdrawnNA

Sponsor: University of Alabama at Birmingham

Conditions: Hypoparathyroidism

Interventions: Parathyroid Allotransplant

Countries: United States

Options for treatment of severe, refractory hypocalcemia are limited for the thousands of patients in the United States who suffer from hypoparathyroidism. Parathyroid allotransplantation is an emerging treatment that provides hope for these individuals. Currently, this therapy has only been successfully provided by a few centers in the world. In the UAB PATH trial, we propose to become one of the few centers worldwide to successfully achieve parathyroid allotransplantation in transplant-naïve patients.
