Abstract
Abaloparatide is a 34-amino acid peptide that selectively binds to the RG conformation
of the parathyroid hormone receptor type 1. It was developed for the treatment of
women with postmenopausal osteoporosis at high risk of fracture. In ACTIVE, an 18-month
phase 3 study (NCT01343004), abaloparatide increased bone mineral density (BMD), decreased
the risk of vertebral and nonvertebral fractures compared with placebo, and decreased
the risk of major osteoporotic fractures compared with placebo and teriparatide. Here,
we report a prospective, exploratory BMD responder analysis from ACTIVE.
