Non-originator low molecular weight heparins: generics or biosimilars

Biosimilars/Research | Posted 06/11/2015

First developed in the 1980s, low molecular weight heparins (LMWHs) are complex anticoagulants derived from porcine intestinal mucosa and are used in the treatment of deep vein thrombosis and pulmonary embolism. Heparin sodium’s anticoagulant activity is mainly governed by its ability to bind to the serine protease inhibitor antithrombin (AT). In this sense, heparin sodium functions as a cofactor for AT by modifying its conformation, thereby accelerating the inactivation of clotting factors.

Biosimilar naming and AE reporting

Biosimilars/Research | Posted 30/10/2015

How will biosimilar naming affect the ability to attribute adverse events (AEs) to a particular product? This is a question researchers from the Tufts Center for the Study of Drug Development (Tufts CSDD) sought to answer [1].

Biosimilars of ranibizumab

Biosimilars/General | Posted 30/10/2015

Last update: 4 December 2020

Ranibizumab is a monoclonal antibody fragment created from the same parent mouse antibody as bevacizumab. Ranibizumab inhibits angiogenesis (the formation of new blood vessels) by inhibiting vascular endothelial growth factor A (VEGF-A), a mechanism similar to bevacizumab [1].

Pharmacovigilance compliance for biocomparables in Mexico

Biosimilars/Research | Posted 16/10/2015

Filgrastim is widely used in Mexico, as in other countries. Its patent has expired and hence several non-originator biologicals have appeared. Following WHO guidelines, the General Health Law of Mexico was modified in 2009 to provide a solid regulatory environment for biosimilars (or biocomparables as they are called in Mexico) [1].

Answers to questions about anti-TNF biosimilars

Biosimilars/Research | Posted 09/10/2015

While the potential pharmacoeconomic benefits of cost-effective biosimilars seem clear, several issues have been raised regarding, for example, the definition of biosimilarity and the validity of indication extrapolation, as well as the ‘switchability’ and relative immunogenicity of biosimilars and their reference drugs. In a review by Isaacs and co-authors, these questions with reference to CT-P13 (Remsima, Inflectra), a biosimilar of the anti-tumour necrosis factor (TNF) monoclonal antibody infliximab (Remicade) were discussed [1].
