Insulin biosimilar meets primary endpoint in phase III studies
US pharma giant Merck announced on 13 June 2016 positive results from two phase III studies evaluating its insulin glargine biosimilar (MK-1293).
Improvement in uptake of biosimilars in Spain
Author Ainhoa Aranguren Oyarzábal and colleagues from the Madrid Health Service (MHS), Spain found that there has been an increase in the uptake of biosimilars in Spain since indicators were introduced [1].
Immunogenicity of biologicals: the role of post-translational modifications
Although produced under strict quality control(s) nascent endogenous proteins and glycoproteins (P/GP) are structurally heterogeneous and subject to further structural changes throughout their in vivo life cycle. A nascent polypeptide chain may be subject to co-translational modifications (CTMs) as it is extruded from the ribosome tunnel, e.g. the addition of oligosaccharide; edited for correct folding and initial oligosaccharide processing within the endoplasmic reticulum and subject to post-translational modifications (PTMs) during passage through the Golgi apparatus. The functional activity of a P/GP may be dependent on further chemical modifications (CMs), e.g. deamidation, enzymatic cleavage. These heterogeneities are compounded when determining the structure of a purified P/GP because further CMs may be introduced during its isolation, purification and characterization [1].
Alvogen opening biosimilars plant in Iceland
Iceland-based biopharmaceutical company Alvotech, a sister company of US generics company Alvogen, is set to open its state-of-the-art 11,800 square meter development and manufacturing facility for biosimilars in June 2016.
Effectiveness of ESAs in treating anaemia in kidney disease and cancer patients
Erythropoiesis-stimulating agents (ESAs) are biological analogues of human erythropoietin used for the treatment of anaemia associated with chronic kidney disease (CKD) and chemotherapy treatment in cancer patients [1]. ESA biosimilars have been available on the Italian market since 2007. However, only limited post-marketing data exist on the comparative effectiveness of biosimilar and originator ESAs in routine care.
Biosimilars of eculizumab
Last update: 20 October 2017
Eculizumab is a humanized monoclonal antibody that is a terminal complement inhibitor. It is used to treat people with paroxysmal nocturnal haemoglobinuria (PNH), for whom it improves quality of life but does not appear to affect the risk of death. It is also indicated for the treatment of patients with atypical haemolytic uremic syndrome (aHUS) – a disease that primarily affects kidney function – to inhibit complement-mediated thrombotic microangiopathy.
Rituximab biosimilar from Sandoz accepted for review by EMA
Sandoz, the generics division of Novartis, announced on 24 May 2016 that its regulatory submission for its proposed rituximab biosimilar (GP2013) had been accepted by the European Medicines Agency (EMA).
Samsung Bioepis infliximab biosimilar accepted for review by FDA
Samsung Bioepis (a Biogen and Samsung joint venture) and Merck announced on 24 May 2016 that the US Food and Drug Administration (FDA) had accepted for review a Biologics License Application (BLA) submitted by Samsung Bioepis for the companies’ infliximab biosimilar candidate, SB2.
Monoclonal antibodies and the challenge of substitution
Healthcare payers are eagerly awaiting the arrival of biosimilar competition in the innovative monoclonal antibody sector in order to drive down drug prices and increase patients’ access to these medicines. As the first to introduce scientific and regulatory requirements for the approval of biosimilars in 2004, the European Union (EU) has emerged as a testing ground for biosimilars. In view of the lack of stance of EU governments and national institutions on substitution for biosimilars, hospitals and healthcare structures logically took up this major issue.
Roche sues India’s drug regulator over Avastin ‘similar biologics’
Switzerland-based drug giant Roche has sued the Drug Controller General of India (DCGI) in the Delhi High Court over ‘similar biologic’ versions of its cancer blockbuster Avastin (bevacizumab).
