Abaloparatide is a synthetic derivative of human parathyroid hormone-related protein (PTHrP) (1-34) and an agonist of parathyroid hormone receptor type 1 (PTH1R).1 It selectively binds to the G protein-dependent (RG) conformation of PTH1R over the G protein-independent (R0) conformation (IC50s = 0.2 and 316.23 nM, respectively). It induces cAMP signaling more transiently than PTH (1-34) , PTHrP (1-36), or the long-acting PTH/PTHrP hybrid peptide analog LA-PTH (EC50s = 0.08, 0.44, 0.46, and 0.21 nM, respectively). Abaloparatide (5 and 20 µg/kg per day for six weeks) increases areal bone mineral density in the lumbar spine, total femur, and femur diaphysis in ovariectomized osteopenic rats.2 It also increases bone strength in the femur diaphysis, femur neck, and L4 vertebra in the same model. Abaloparatide increases the incidence of focal osteoblast hyperplasia, benign osteoblastoma, and osteosarcoma in rats in a time- and dose-dependent manner when administered at doses greater than or equal to 10 µg/kg per day for up to two years.3 Formulations containing abaloparatide have been used in the treatment of osteoporosis in postmenopausal women at high risk for bone fracture.

Teriparatide(TPTD)products that can be used clinically in Japan include a daily subcutaneous injection form produced by genetic engineering and a weekly subcutaneous injectable TPTD acetate form produced by chemical synthesis. Published reports indicate that both forms exhibit excellent antifracture efficacy, and as the only anabolic agents that promote osteogenesis, TPTD products now occupy a prominent position. However, the two forms differ considerably, not only in frequency of administration, but also in mechanism of action. The daily form stimulates osteogenesis and accompanying resorption through more radical high bone turnover, and early in the course of treatment, intracortical porosity and apatite crystallization decrease, while immature collagen crosslinking increases. However, because daily formulations also produce an increase in cortical surface area or cortical thickness, the effects are counterbalanced, and bone strength is maintained. In contrast, the weekly form prioritizes osteogenesis, and by concurrently lowering turnover below pretreatment levels, improves trabecular bone mass and structure, and enhances strength without leading to cortical porosity and other undesirable phenomena. Abaloparatide, a PTHrP(1-34)analog that is homologous with the biologically active site of PTH drugs, is currently under development, and we eagerly anticipate further clarification of the mechanism of action of each formulation on bone.
