Do patent strategies delay market entry of biosimilar monoclonal antibodies in Europe?

Biosimilars/Research | Posted 22/05/2020

Patents have been shown to be the main determinant to guarantee market exclusivity of originator biologicals [1], with patent disputes causing uncertainty on a patent’s validity and subsequently potentially influencing launch dates of competitor products, such as biosimilars [2]. In addition, the launch date of a biosimilar might be affected by strategies for prolongation of exclusivity rights on the originator product, such as filing additional patents for a new formulation, new indication or new dosage regime [3].

Scientific evidence in development of trastuzumab biosimilar ABP 980

Biosimilars/Research | Posted 15/05/2020

ABP 980 (Kanjinti) is a biosimilar to trastuzumab reference product (RP) (Herceptin), a monoclonal antibody directed against human epidermal growth factor receptor 2 (HER2). A biosimilar is highly similar to a licensed biological with no clinically meaningful differences in safety, purity and potency [1, 2]. Kanjinti is approved in the US, European Union, and as trastuzumab BS [trastuzumab biosimilar 2] in Japan for all Herceptin indications, which include treatment of HER2 positive (HER2+) metastatic breast cancer, early breast cancer (EBC), and metastatic gastric cancer [3-5]. Development and approval were based on a totality of evidence (TOE) approach, involving stepwise generation of comparative analytical (structural and functional), preclinical, and clinical (pharmacokinetics [PK], pharmacodynamics [PD], efficacy, safety and immunogenicity) evidence [6].

Biosimilar education gaps in oncology

Biosimilars/Research | Posted 15/05/2020

A survey administered by the International Society of Oncology Pharmacy Practitioners (ISOPP) identifies key educational needs on biosimilars amongst its practitioners, including how to compare a biosimilar to an originator and how to manage switching [1].

Non-innovator biologicals in India: regulatory context and areas for improvement

Biosimilars/Research | Posted 04/05/2020

There are major regulatory lapses in the manufacturing of similar biologics in India. The use of scientific audits could strengthen the regulatory system and improve the provision of high quality biosimilars in the country, according to a recent opinion piece [1] by Dr GR Soni, which was published in GaBI Journal.

The clinical trials used to support the approval of Amgen’s ABP 501 (Amjevita/Amgevita/
Solymbic) were critically reviewed by authors from Argentina and the UK [1].

Clinical trials supporting the approval of adalimumab biosimilars

Biosimilars/Research | Posted 03/04/2020

Authors from Argentina and the UK critically review the evidence from trials of biosimilars in rheumatoid arthritis (RA) [1].

Assessment of biosimilarity for monoclonal antibodies

Biosimilars/Research | Posted 24/04/2020

How therapeutic monoclonal antibody biosimilars are assessed for biosimilarity, was discussed by authors from the National Institute of Health Sciences and the Yokohama University of Pharmacy in Japan. Their review covers the basic concept of biosimilar development as well as pharmacokinetic data obtained via non-clinical and clinical studies of biosimilar therapeutic antibodies [1].

Positive phase III results for Hisun’s adalimumab copy biological

Biosimilars/Research | Posted 10/04/2020

Positive results were reported from a phase III trial of an adalimumab copy biological, HS016, which compared the candidate adalimumab copy biological HS016 with originator adalimumab Humira for the treatment of active ankylosing spondylitis (AS) [1].
