Positive Hypoparathyroidism Trial Data: AstraZeneca
AstraZeneca says recent data from the CALYPSO Phase 3 hypoparathyroidism trial showed that eneboparatide, an investigational parathyroid hormone (PTH) receptor 1 agonist, met its primary endpoint with “statistical significance.” The company says the trial is evaluating the therapy’s use in adults with chronic hypoparathyroidism (HypoPT) at 24 weeks, compared to placebo. The primary endpoint is a composite of albumin-adjusted serum calcium level normalization and independence from active vitamin D and oral calcium therapy, it says
HypoPT is a rare endocrine disease caused by a deficiency of PTH that leads to impaired regulation of calcium and phosphate levels in the blood, according to AstraZeneca, adding that this can lead to clinical manifestations, including negative impacts on the kidneys and bones.
During the trial, eneboparatide was well tolerated, AstraZeneca says. Full efficacy and safety data will be analyzed at 52 weeks, it says, and data will be shared with global regulators.
