Alexion, AstraZeneca Rare Disease, will deliver 16 presentations, including three oral presentations, across hypophosphatasia (HPP), chronic hypoparathyroidism (HypoPT) and early research at the American Society for Bone and Mineral Research (ASBMR) Annual Meeting in Boston, Massachusetts, 9 to 12 October 2026.
Highlights include:
HICKORY: results from Phase III trial of efzimfotase alfa (ALXN1850) in treatment-naïve adolescents and adults with HPP CALYPSO: data on skeletal parameters from Phase III trialevaluating eneboparatide, an investigational parathyroid hormone (PTH) 1 receptor agonist, in adults with HypoPT
Gianluca Pirozzi, Senior Vice President, Head of Development, Regulatory and Safety, Alexion, said: “At this year’s ASBMR Annual Meeting, findings across 16 presentations will notably demonstrate the breadth of our research in HPP and HypoPT, two rare, multisystemic diseases that can have far-reaching impacts on patients’ daily lives. In HPP, results from HICKORY, the first Phase III clinical trial to include patients with adult-onset disease, will further reinforce the potential of efzimfotase alfa to reduce treatment burden and redefine care expectations, while real-world evidence will provide important insights into the impact of HPP. Together with new bone data from the CALYPSO Phase III trial of eneboparatide in HypoPT, our presence reflects our commitment to developing meaningful innovations that address the needs of patients and their families.”
