Similar biotherapeutic products under development in Latin America

Last update: 15 November 2013

Similar biotherapeutic products are high on the health policy agenda in Latin America, due to the fact that they are less costly and therefore have the potential to increase access to life-saving drugs. Within individual Latin American countries, the regulatory processes and stages of implementation of similar biotherapeutic products regulation vary widely. Despite this, Latin America is moving towards increasing standards of regulation for these products [1, 2].

Use of similar biotherapeutic products to treat rheumatoid arthritis in Latin America

Latin America has a significantly lower gross domestic product (GDP) compared to Canada, Europe and the US. Despite this fact, the cost of biologicals is in general very similar to countries with higher GDP, causing problems for patients to gain access to these medications. This problem could possibly be solved by the introduction of lower-cost biosimilars to the region.

Establishing mAb biosimilarity before reaching the clinic

Confirming the biosimilarity of monoclonal antibodies (mAbs) is fraught with challenges beyond those faced by currently approved biosimilars, warn Ebbers and co-authors at Utrecht University, The Netherlands [1]. The threat of unexpected immunogenicity has been well reported, but the problems do not start there. The first steps towards establishing the biosimilarity of an anticancer mAb, the preclinical stage, presents challenges of its own.
