Biosimilars of teriparatide Posted 03/03/2017

Last update: 9 May 2017

Teriparatide is a recombinant form of parathyroid hormone (PTH). Teriparatide is identical to a portion of human PTH and intermittent use activates osteoblasts more than osteoclasts, which leads to an overall increase in bone. This makes it an effective anabolic, i.e. bone growing, agent. It is therefore used for the treatment of osteoporosis in postmenopausal women and men at high risk for fracture and for glucocorticoid-induced osteoporosis in men and postmenopausal women.

The originator product, Eli Lilly’s Forteo/Forsteo (teriparatide), was approved by the US Food and Drug Administration (FDA) in November 2002 and by the European Medicines Agency (EMA) in June 2003 [1]. Forteo/Forsteo had worldwide sales of US$1.3 billion in 2015.

The patents on Forteo/Forsteo expire in the US and in Europe in August 2019 [1]. Some of the teriparatide biosimilars and non-originator biologicals* approved or in development are presented in Table 1.

EMA’s Committee for Medicinal Products for Human Use (CHMP) announced on 11 November 2016 that it had recommended granting of marketing authorization for the teriparatide biosimilars, Movymia and Terrosa, produced by German generics giant Stada Arzneimittel (Stada) and Hungary-based Gedeon Richter (Richter), respectively [4].

Editor’s comment
It should be noted that ‘similar biologics’ approved in India might not have been authorized following as strict a regulatory process as is required for approval of biosimilars in the European Union. EMA (European Medicines Agency) regulatory requirements ensure the same high standards of quality, safety and efficacy for biosimilars as for originator biologicals, and also include a rigorous comparability exercise with the reference product.
