Biosimilars/Research
Biosimilar uptake and the education of healthcare provider
Affordability and access. Two simple words that nevertheless convey the complex burdens facing many healthcare systems around the world. And within the healthcare realm, there is likely no aspect that embodies issues related to affordability and access more than prescription medicines.
Biosimilar reimbursement rules cost Medicare over US$1.5 billion
Current Medicare Part B biosimilar reimbursement rules prevented healthcare savings of over US$1.5 billion between 2015 and 2019, revealed a study published in JAMA Network Open [1].
Evidence on automatic substitution of biologicals is limited
A systematic review of the evidence on automatic substitution of biological medicines [1] finds that current research evidence is mainly based on opinion polls and surveys of low-to-moderate quality, with results that are not generalizable or suitable for guiding policy.
Definition of biological terms in Latin America
To conduct a comparative study of the health registration regulations for biological and biotechnological drugs in Latin America, Ramírez-Telles et al. made an approximation, as clear as possible, of biological terms: regulatory authority of reference, biotechnological drug, reference biological drug and innovative product. Its objective was to detect the differences and what these variations entailed when comparing the following Latin American countries: Brazil, Chile, Costa Rica, Cuba, Dominican Republic, El Salvador, Guatemala, Honduras and Panama [1].
Biosimilar mAb development – quality similarity considerations
Since 2013, when the first biosimilar monoclonal antibody (mAb) was approved by the European Medicines Agency (EMA), the number of approved biosimilar mAbs has been increasing dramatically [1]. The large number of approved biosimilar mAbs in both the European Union (EU) and the US makes the evaluation of these applications possible from a product quality perspective.
Advances for Samsung Bioepis’ eculizumab and trastuzumab biosimilars
Samsung Bioepis has announced the completion of its global phase III clinical trials of a biosimilar of Soliris (eculizumab), for treating certain rare blood diseases. In addition, it also presented its results from a five-year follow-up study that showed its biosimilar Ontruzant (trastuzumab) has comparable cardiac safety profiles and long-term efficacy as the originator, Herceptin.
Regulation of the registration of biological drugs in Latin America
Biological drugs are defined as products with active ingredients produced from a biological source, whereas a biotechnological product is developed from the isolation of a gene of interest and its cloning [1].
Biosimilars: Promises made. Promises kept?
Biosimilars are biological products that are highly similar to their reference biologicals. Biosimilars are designed to have comparability with respect to quality, safety and efficacy compared to an already licensed reference biological. Most regulatory agencies, including the European Medicines Agency (EMA), do not require a full clinical dossier for a biosimilar. It is usually possible to carry out one clinical trial in one indication, with the option to extrapolate to other indications of the reference biological [1].
Progress in the regulation of biosimilars in the EU
Analysis of regulation of biosimilars in the EU concludes that regulation is progressing as more knowledge is gained, which is reflected in the changing nature of regulatory guidelines. The authors conclude that the EU framework generates safe and effective biosimilars [1].
Biosimilars, clinical management and incentives
The aim of a study carried out by Spanish researchers was to identify and analyse policies applied in the health services to enhance uptake of biosimilars in the framework of clinical management settings [1]. Incentives, both financial and non-financial, were of particular interest for the authors. They reviewed the relevant experiences developed in different high-income countries with advanced healthcare systems. In addition, they investigated barriers to the implementation of these policies in Spain.
YLB113 etanercept biosimilar autoinjector 'safe and effective’
Analysis of the YLB113 etanercept autoinjector, a biosimilar to reference etanercept, finds a high rate of injection success and supports the safe and effective use of YLB113 [1].
Progress for bevacizumab copy biologicals from Henlius and Innovent
Shanghai Henlius Biotech, Inc (Henlius) reports progress in clinical trials of a bevacizumab copy biological for age-related macular degeneration and colorectal cancer, while Innovent Biologics reports positive findings from a trial of their bevacizumab copy biological in hepatocellular carcinoma.
Data support the interchangeability of EU biosimilars
The first study to comprehensively analyse post-marketing surveillance data for biosimilar monoclonal antibodies demonstrates comparable efficacy, safety and immunogenicity with the originator products [1].
Patent litigation insights on barriers to US biosimilar market growth
High prices of biological drugs have placed substantial strain on the US healthcare system. To help address this problem, Congress passed the Biologics Price Competition and Innovation Act of 2009 (BPCI Act) as part of the Affordable Care Act, which created an abbreviated approval pathway for biosimilars – versions of ‘originator’ biological drugs made by different manufacturers. To resolve disputes over whether a biosimilar manufacturer would infringe patents on the originator biological by entering the market, the BPCI Act included a multi-step litigation process, which starts when the biosimilar manufacturer submits its abbreviated biological license application to the US Food and Drug Administration (FDA). However, a decade after its passage, the BPCI Act has spurred only limited competition [1].
Research, development and public production of pharmaceuticals in Argentina
Under the current research and development model, the pharmaceutical industry has switched its focus towards the therapeutic areas that offer the greatest commercial benefit, which are often not aligned with public health needs. Consequently, it has ceased to be the great innovative industry that it had been during the last century.
Delayed biosimilars market entry costs US billions
Delayed adalimumab biosimilar entry to the US market is estimated to have cost Medicare over US$2.19 billion between 2016 and 2019, a study published in Clinical Pharmacology and Therapeutics has revealed.
Demand for similar biotherapeutic products in Latin America
Development of biologicals has experienced steady growth over the past three decades. Expiration of patents on many originator biologicals, such as insulin, human growth hormone and erythropoietin, has opened the door for the development of biosimilars. The high cost of biologicals, however, has limited their accessibility, particularly in developing countries. Biosimilars offer much-needed affordability and hence improved accessibility. Global health agencies, such as the World Health Organization, are engaged in developing a prequalification program in order to help countries that do not have strong regulatory systems [1].
Competition from biosimilars drives price reductions for biologicals in France
The US has experienced a policy debate as to whether competition from biosimilars is the best strategy for achieving price reductions for biologicals or, rather, whether direct price regulation after loss of patent exclusivity would be more effective. In order to investigate this issue, authors from the US and France combined quantitative and case study methods to examine in detail the interaction between market and administrative mechanisms to reduce biologicals’ prices in France. In their article they present comprehensive data on market shares and prices for three major biologicals and their 11 competing biosimilars between 2004 and 2020 [1].
Positive trial results for bevacizumab copies from Betta Pharmaceuticals and Biocad
The bevacizumab copy biological MIL60 (Betta Pharmaceuticals Ltd) and non-originator biological BCD-021 (Biocad) have demonstrated clinical equivalence for the treatment of non-squamous non-small cell lung cancer (NSCLC) in phase III trials.
Candidate trastuzumab biosimilar AryoTrust
Biologicals are one of the interesting and effective treatment options which can save the lives of many patients, however, their high cost and restricted access for some patients remains a challenge. The emergence of biosimilars, with their similar efficacy and safety profiles, could be a solution for this hurdle. According to the European Medicines Agency (EMA) guidance entitled ‘Biosimilars in the EU – information guide for healthcare professionals’, a biosimilar is ‘a biological medicine highly similar to another biological medicine already approved in the EU’ [1]. Biosimilars are required to have the same standards of pharmaceutical quality, safety and efficacy as for originator biologicals in order to obtain marketing authorization. Although, according to the EMA guidance ‘approval of biosimilars builds on existing scientific knowledge on safety and efficacy of the reference medicine gained during its clinical use, so fewer clinical data are needed’ [2].
