Abaloparatide

Abaloparatide is an N-terminal analog of parathyroid hormone-related protein (PTHrP) and an agonist at the parathyroid hormone type 1 (PTH1) receptor. It is a synthetic 34 amino acid peptide with 41% homology to human parathyroid hormone 1-34 and human PTHrP 1-34. Abaloparatide and PTHrP share the first 21 amino acids and the receptor-activating domain.

Abaloparatide is an osteoanabolic agent that stimulates bone formation. It was first approved by the FDA on April 28, 2017, for the treatment of osteoporosis in postmenopausal women and is also used to increase bone density in men with osteoporosis. In October 2022, the EMA's Committee for Medicinal Products for Human Use (CHMP) recommended abaloparatide be granted marketing authorization in Europe and the drug was fully authorized by the European Commission on December 19, 2022.

Abaloparatide is indicated for the treatment of postmenopausal women with osteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture) or patients who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, abaloparatide reduces the risk of vertebral and nonvertebral fractures.

Abaloparatide is also indicated to increase bone density in men with osteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture) or patients who have failed or are intolerant to other available osteoporosis therapy.
