Insulin biosimilar Semglee gains EC and Australian approval
India-based Biocon and US-based partner Mylan announced on 28 March 2018 that they had received European Commission (EC) and Australian approval for their co-developed insulin glargine biosimilar, Semglee.
Government policies to maximize social benefit of biosimilars in countries with restricted access to biologicals
The potential value of biosimilars is dependent on patient access to originator biologicals in a given country. If the originator biological is reimbursed without any volume and access restrictions, the main objective of using biosimilars is to generate savings in health expenditures without compromising health outcomes. This disinvestment scenario is mainly applicable for higher income countries. If the original biological product is reimbursed with volume and access restrictions, the main objective of biosimilars is to treat more patients from the same healthcare budget, and hence generate more health gain. This special investment scenario is applicable for lower income European Union (EU) Member States and other middle-income countries. If the originator biological is not reimbursed at all, more affordable biosimilars may create an opportunity for public reimbursement, however, incremental budget is needed to generate more health gain. This investment scenario is applicable for low-income countries [1].
Trastuzumab biosimilar Ontruzant launched in the UK
Merck Sharp and Dohme (MSD), which is known as Merck in the US and Canada, announced on 8 March 2018 that it had launched the trastuzumab biosimilar, Ontruzant, in the UK.
Yoshindo and Lupin’s etanercept biosimilar completes trials
YL Biologics announced on 7 February 2018 that the global phase III trials of its etanercept biosimilar have been a success. YL Biologics is a joint venture of India’s Lupin Ltd and Japanese firm Yoshindo that was first announced in 2014 [1]. The etanercept biosimilar has met a successful outcome for rheumatoid arthritis treatment and hopes to compete for a share of the originator Enbrel’s global market of US$11 billion.
PK and PD comparison between rituximab biosimilar RTXM83 and rituximab in diffuse large B-cell lymphoma patients
A requirement for registration of a biosimilar is to demonstrate pharmacokinetic (PK) similarity with the reference product. A population PK model approach is an excellent method for assessing PK similarity, in contrast to the classical one, because it allows comparison of PK properties through the inclusion of sparse data that improves the power to detect any potential differences between the biosimilar and the reference product. Furthermore, the population approach allows quantification of the inter-product and inter-subject variability of PK parameters and identification of covariate factors (demographic, pathophysiological, environmental or concomitant drugs) that influence drug availability [1].
Follow-on biologicals and extrapolation in Brazil
Researchers from Brazil discuss the country’s approach to follow-on biologicals and extrapolation of indications in the country [1].
Insulin glargine biosimilar gains South Korean approval
South Korea-based GC Pharma (formerly Green Cross Corporation) announced on 8 March 2018 that it had received approval for its insulin glargine biosimilar Glarzia from the Korean Ministry of Food and Drug Safety (MFDS).
Biosimilar policies around the globe
With the authorization of an increasing number of biosimilars, and the prospect of multiple biosimilar switching, biosimilar naming and the importance of this for pharmacovigilance are coming into sharper focus. Authors from around the world considered various biosimilar issues/policies in different countries and regions [1].
US drug contracting system is ‘rigged’ against biosimilars
US Food and Drug Administration (FDA) Commissioner Dr Scott Gottlieb has said that the drug contracting system in the US is ‘rigged’ against biosimilars. His remarks came during a speech he made on 7 March 2018 at the America’s Health Insurance Plans National Health Policy Conference in Washington DC.
ASCO issues position statement on biosimilars in oncology
The American Society of Clinical Oncology (ASCO) has issued a position statement on biosimilars in oncology. The statement reflects the society’s views on issues such as naming, labelling, safety and efficacy, interchangeability, switching and substitution of biosimilars, as well as on the value of biosimilars and prescriber and patient education [1].
