Biosimilars
The role of the patient in treatments with biosimilars in Argentina
This is how Dr Eduardo Mysler, Medical Director for the Research Medical Organization (OMI) and rheumatology specialist with a long research career reflects that ‘patients have to understand all the details of their disease’.
Trastuzumab emtansine ‘similar biologic’ Ujvira launched in India
India-based generics manufacturer Zydus Cadila (Zydus) announced on 24 May 2021 the launch of its trastuzumab emtansine ‘similar biologic’ Ujvira in India. The launch, according to Zydus ‘marks the world’s first biosimilar antibody drug conjugate (ADC) of trastuzumab emtansine’.
Positive phase III results for tocilizumab biosimilar BAT1806
US biotechnology company Biogen Idec (Biogen) and China-based Bio-Thera announced on 1 June 2021 positive phase III data for their tocilizumab biosimilar, BAT1806. According to the two companies, ‘the comparative study met its primary endpoints and showed equivalent efficacy and comparable safety profile in patients with moderate-to-severe rheumatoid arthritis’.
US Supreme Court rejects Enbrel patent challenge from Sandoz
The US Supreme Court has declined to review a patent challenge from Sandoz on Amgen’s blockbuster anti-inflammatory, Enbrel (etanercept). This means Sandoz will not be able to launch its etanercept biosimilar, Erelzi (etanercept-szzs), on the US market until 2029.
Efficacy and safety of Yuflyma vs reference adalimumab in rheumatoid arthritis
Yuflyma (CT-P17) is an adalimumab biosimilar, administered at 100 mg/mL that also has the same citrate-free and high concentration formulation of reference adalimumab. To demonstrate the bioequivalence of CT P17 to reference adalimumab, a randomized, double-blind, active-controlled study in subjects with moderate to severe rheumatoid arthritis (RA) was conducted [1]. The study was designed to demonstrate equivalence of efficacy (ACR20* response rate at Week 24) for CT P17 versus reference adalimumab and to evaluate additional efficacy, pharmacokinetics (PK), usability and safety over one year.
Positive phase I results for Meiji’s ustekinumab biosimilar
Japan-based Meiji Seika Pharma (Meiji) announced on 21 May 2021 positive phase I results for its candidate ustekinumab biosimilar, DMB-3115.
Clinical trials for aflibercept biosimilars
Sandoz, the generics division of Novartis, has announced the start of a phase III clinical trial of its aflibercept (Eylea) biosimilar, a treatment for age-related macular degeneration. Clinical trials for a number of competitive biosimilars are also underway.
Biosimilar pipelines for South Korean firms: Celltrion and Samsung Bioepis
Biosimilars are becoming more important around the world and Korean companies, such as Celltrion Healthcare (Celltrion) and Samsung Bioepis (Samsung and Biogen’s joint venture), are fast becoming major players both in Korea but also worldwide.
Review and meta-analysis of biosimilars for the treatment of rheumatoid arthritis
Authors from Japan provide a new perspective on biosimilars for management of rheumatoid arthritis (RA) to provide evidence of efficacy and safety of biosimilars compared with reference biological disease-modifying anti-rheumatic drugs (bDMARDs) (reference bDMARDs) in patients with RA as a part of the process of developing the 2020 update of the Japan College of Rheumatology (JCR) guidelines for the management of RA [1].
On the edge of transition: European biosimilar clinical trial requirements
Recent debates have focused on the clinical trial requirements for biosimilar approval [1-4]. Further, the regulatory approval of biosimilars in the European Union (EU) has been changed, where in some instances and under certain conditions clinical trials to establish comparable efficacy have been excluded [4]. Still, the regulatory recommendation for more complex molecules such as monoclonal antibodies is without exception to conduct clinical comparability trials [4].
