Brazilian oncologists favour ‘follow-on biological products’
The Brazilian Society of Clinical Oncology (SBOC) has issued a position statement on ‘follow-on biological products’ in oncology. The statement reflects the society’s views on issues such as naming, labelling, safety and efficacy, extrapolation of indications, interchangeability, switching and substitution of ‘follow-on biological products’, as well as on the potential impact ‘follow-on biological products’ may have on the financial burden in health care [1].
Secrecy is an obstacle to the use of biosimilars in the US
Factors that Professor Frank believes may be affecting uptake include naming and interchangeability guidance, insurance payment arrangements and secrecy about manufacturing processes [1]. In this article, secrecy about manufacturing processes is discussed.
Biosimilar etanercept Eucept approved in South Korea
South Korea-based LG Chem has obtained regulatory approval to begin marketing and selling its etanercept biosimilar in Korea.
Safety of biosimilar infliximab in pregnant women with IBD
Introduction of the first biosimilar infliximab (CT‑P13, Remsima/Inflectra) for the treatment of inflammatory bowel diseases (IBDs) was aimed to reduce the healthcare cost burden and to increase the number of treated individuals with similar treatment results. Shortly after CT‑P13 has been authorized for usage in clinical practice, many concerns arose due to the fact that the principle of extrapolation of limited clinical results had been applied to the biosimilar, which led to approval of the biosimilar in all the indications of the originator biological (Remicade). However, these concerns have proved to be unfounded, as subsequent studies have confirmed the similar efficacy, safety and immunogenicity of CT‑P13 and Remicade in the general IBD population [1].
Biosimilars highlights for 2017
There are many product launches and various topics such as naming, extrapolation, interchangeability and switching of biosimilars in 2017 [1]. Important milestones achieved during 2017 were the biosimilar approvals of Renflexis (infliximab-abda), Cyltezo (adalimumab-adbm), Mvasi (bevacizumab-awwb), Ixifi (infliximab‑qbtx), and Ogivri (trastuzumab-dkst), along with the approval of follow-on insulin lispro biological Admelog, by the US Food and Drug Administration (FDA).
Insurance payment arrangements are an obstacle to biosimilars use in the US
The slow development of the market competition for biosimilars in the US may be caused by several factors, according to Professor Richard Frank from the Department of Health Care Policy, Harvard Medical School, Boston, USA [1]. In this article, insurance payment arrangements for biologicals and biosimilars are discussed.
FDA rejects trastuzumab and rituximab biosimilars
US pharma giant Pfizer announced on 23 April 2018 that the US Food and Drug Administration (FDA) had rejected its application for approval of its trastuzumab biosimilar. Then Sandoz, part of Novartis, announced on 2 May 2018 that its biosimilar rituximab application had also been rejected.
Biosimilars in rheumatology: the current state of play
Biological disease modifying anti-rheumatic drugs (bDMARDs) have revolutionized the management of rheumatoid arthritis (RA) and other inflammatory diseases. Over two decades, their use has risen exponentially but their significant cost has contributed to increasing healthcare expenditure in many countries. Biosimilar development is an opportunity to lower drug expenses and optimize use. This review detailed the current state of biosimilars in rheumatology, including their development, trial data, economic impact and logistical considerations [1].
