Regulation and uptake of ‘similar biologics’ in India

India has, by far, demonstrated the greatest acceptance of ‘similar biologics’. But what are the drivers and the limitations to the ‘similar biologics’ market in India? This is a question Dr Nagaraj Malipatil, a clinical pharmacologist, from Bangalore, India tried to address in his review of similar biologics in India [1].

Assessing the immunogenicity of monoclonal antibodies

Safety is a major concern when it comes to biologicals (including biosimilars) and the most critical safety concern is immunogenicity. This is especially important in monoclonal antibody (mAb) biologicals, which are large molecules with complex structures and functions and which represent the largest class of biologicals [1].

Positive phase III results for adalimumab biosimilar

US-based biologicals giant Amgen announced on 9 November 2015 that results from a phase III study of its adalimumab biosimilar (ABP 501) had ‘met the primary endpoint’.

AE reporting for biologicals

Researchers from the Tufts Center for the Study of Drug Development (Tufts CSDD) sought to answer [1] examined primary suspect reports sent to the US Food and Drug Administration’s (FDA) Adverse Event Reporting System (FAERS) from US reporters for two biologicals that have lost patent exclusivity – somatropin and human insulin. The study was carried out to inform both FDA and the global drug development community about how naming of biosimilars might affect the traceability of adverse events (AEs).

Positive phase III results for etanercept biosimilar

On 9 November 2015, biopharmaceutical specialists Coherus and Baxalta (a spin-off company from Baxter International) announced positive results from a phase III study of its etanercept biosimilar (CHS-0214).

Biosimilar naming conventions around the world

Naming conventions from around the world was one of the topics investigated in a study by researchers from the Tufts Center for the Study of Drug Development (Tufts CSDD) [1].

Positive phase III results for Samsung Bioepis biosimilars

Results of phase III clinical studies of candidate etanercept biosimilar SB4 infliximab biosimilar SB2 and adalimumab biosimilar SB5 have all met their primary endpoints, according to an announcement on 7 November 2015 by Samsung Bioepis (a Biogen and Samsung joint venture).

Biosimilars and interchangeability

In a study by researchers from the Tufts Center for the Study of Drug Development (Tufts CSDD) the question of interchangeability around the world was one of the topics investigated [1].

Economic considerations for rheumatoid arthritis biosimilars

In the paper by Gulácsi et al. [1], the authors stated that biosimilars have the potential to reduce costs and increase patient access to biologicals in the treatment of rheumatoid arthritis (RA) and other chronic inflammatory rheumatic and bowel diseases.

Non-originator low molecular weight heparins: generics or biosimilars

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.
