Positive phase I results for adalimumab biosimilar

In an announcement on 28 October 2015, biopharmaceutical specialist Boehringer Ingelheim Pharmaceuticals (Boehringer Ingelheim) claimed that results from a phase I study of its adalimumab biosimilar (BI 695501) had ‘demonstrated pharmacokinetic bioequivalence’ to Humira (adalimumab).

Biosimilar naming and AE reporting

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].

Rituximab biosimilar claimed similar pharmacokinetics to originator

A phase I/II study of Pfizer’s rituximab biosimilar candidate PF-05280586 has shown similar pharmacokinetic (PK) properties, according to Jacobs and co-authors [1].

Biosimilars use in Italy increasing

A study of the use of biosimilars in four large Italian geographic areas has found that the use of biosimilar erythropoiesis-stimulating agents (ESAs), especially in naïve patients, increased significantly during the years 2009–2013 [1].

Candidate infliximab biosimilar SB2 equivalent to Remicade

Results from a phase III clinical trial for a candidate biosimilar version of infliximab in patients suffering from rheumatoid arthritis has shown SB2 to be equivalent to Remicade [1].

Pharmacovigilance compliance for biocomparables in Mexico

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].

Positive phase I results for pegfilgrastim biosimilar

US-based biosimilars developer Coherus BioSciences (Coherus) announced on 1 October 2015 that results from a phase I study of its pegfilgrastim biosimilar (CHS‑1701) had met its primary endpoint.

Answers to questions about anti-TNF biosimilars

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].

Biosimilar epoetin-α as effective as originator in anaemia treatment

A study by researchers in Italy has concluded that biosimilar epoetin‑α appears to be comparable to originator epoetin‑α plus liposomal iron (Sideral), vitamin B12 and folates in terms of efficacy and safety for the treatment of refractory anaemia [1].

Biosimilar etanercept safe and effective

In a study funded by Samsung Bioepsis (a Biogen and Samsung joint venture), their candidate etanercept biosimilar (SB4) has been found to be safe and well tolerated and to be equivalent in terms of efficacy compared to Enbrel (etanercept) in patients with rheumatoid arthritis (RA) [1].
