Teriparatide is a recombinant form of parathyroid hormone (PTH). It is identical to a portion of human PTH,and intermittent use activates osteoblasts more than osteoclasts, leading to an overall increase in bone formation. This makes it an effective anabolic, i.e., bone growing, agent. It is indicated for the treatment of osteoporosis in postmenopausal women and men at high risk of fracture, as well as  for glucocorticoid-induced osteoporosis in these populations. The originator product is Eli Lilly’s Forteo/Forsteo (teriparatide) [1] 

CinnaGen’s teriparatide biosimilar, Zandoriah, will be available as a 20 µg/80 µl solution for injection in pre-filled pens. Data submitted to the CHMP demonstrate that Zandoriah has comparable quality, safety, and efficacy to the reference product, Forsteo.

Zandoriah is recommended for the treatment of osteoporosis in postmenopausal women and in men at increased risk of fracture, and for the treatment of osteoporosis associated with sustained systemic glucocorticoid therapy in women and men at increased risk for fracture.

If approved by the European Commission, Zandoriah would become the fifth teriparatide biosimilar authorized in the European Union (EU). Others include Accord’s Sondelbay, Theramex’s Livogiva, Stada’s Movymia, and Gedeon Richter’s Terrosa.

Zandoriah represesnts CinnaGen’s first biosimilar to receive a positive CHMP opinion for the EU market.
