Biotech drugs need adequate patent protection

Biosimilars/News | Posted 14/09/2009

The US government could establish “a properly constructed biosimilars pathway” by providing original developers of biotech drugs with at least 12 years of intellectual property protection to allow them to recover their investments in such treatments, writes former Vermont Governor, Mr Howard Dean, in his commentary. Two bills for follow-on biologics introduced in the House and Senate "include a balanced approach that protects patient safety and encourages research that helps bring new, more advanced treatments – and even cures – to patients around the world," Mr Dean writes.

Europe is biosimilar testing ground, but US will be key market

Biosimilars/News | Posted 07/09/2009

As the Federal Trade Commission weighs into the biosimilars debate in the US and the Obama administration considers seven years of market exclusivity enough for brand biologicals, new research by independent market analyst Datamonitor predicts that the success of the emerging biosimilars industry hinges on access to this market.

US: Biotech drugs need only seven years protection

Biosimilars/News | Posted 04/09/2009

Biological drugs should be subject to generic competition in the US after seven years, the Obama administration said, calling it a ‘generous compromise’. Brand-name companies have lobbied for 12 to 14 years of exclusivity, while Mr Waxman proposed only five. As reported by Bloomberg News, access to cheaper copies of medicines made by biotechnology companies is ‘a key element’ in reducing healthcare costs, White House officials said in a letter to Representative Henry Waxman. “Lengthy periods of exclusivity will harm patients by diminishing innovation and unnecessarily delaying access to affordable drugs,” it said.

Biosimilars and biopharmaceuticals: the ERA-EDTA position

Biosimilars/Research | Posted 05/08/2009

In a position paper by the European Renal Association - European Dialysis and Transplant Association (ERA-EDTA) Council in Nephrology Dialysis Transplantation written by Adrian Covic of the Parhon University Hospital in Iasi, Romania – who received financial gratitude for congress participation, lectures and clinical trials from: Amgen, Affimax, F. Hoffmann-La Roche and Janssen-Cilag – and co-authors, it is stated that biosimilars may offer considerable advantages to hard-pressed healthcare economies, as the costs of providing effective therapies in a variety of new and existing disease areas increase progressively. However, a decision to permit their use clinically should be balanced by a clear mandate to ensure as with all biopharmaceutical agents, that patients, physicians and pharmacists truly understand the complex arguments and decisions which apply to this new and challenging area. In particular, pharmacovigilance is a responsibility that is shared between the pharmaceutical industry, pharmacists and physicians, with appropriately informed and educated patients. Ease of tracing and identification of new/substituted agents especially when dealing with patients who may be exposed to injected therapies for many years is a pivotal requirement and one where new input into nomenclature decisions and systems is now urgently needed. Any decision to employ biosimilar biopharmaceuticals should be taken with appropriate knowledge and understanding of this complex area by the primary responsible physician, after a careful appraisal of the advantages and disadvantages of taking this course of action, and with appropriate systems for pharmacovigilance in place.

The challenge of biosimilars

Scientific and legal viability of follow-on protein drugs

Biosimilars/Research | Posted 05/08/2009

Since recombinant human insulin (Humulin) became the first recombinant-protein drug approved by the FDA 25 years ago, nearly 100 recombinant-protein therapeutics including other hormones and monoclonal antibodies, have become part of clinical practice. Though small-molecule drugs are more common than recombinant-protein drugs – only one of the top 200 prescribed drugs of 2006 (on the basis of prescription volume) was a recombinant protein – protein-based therapeutics have been used to treat diabetes and anaemia, as well as relatively rarer conditions, such as rheumatoid arthritis, Gaucher's disease, and multiple sclerosis.

Economic issues with follow-on protein products

Biosimilars/Research | Posted 30/07/2009

The economic effects of the possible introduction of follow-on protein products have been the subject of recent debate.

Key issues with biosimilars: manufacturing impacts

Biosimilars/Research | Posted 30/07/2009

The first generation biopharmaceuticals are copies of endogenous human proteins, such as erythropoietin, insulin, growth hormones and cytokines, developed using recombinant DNA technology or hybridoma techniques. These compounds have revolutionised the treatment of many diseases, including anaemia, cancer, diabetes, hepatitis and multiple sclerosis. With expiring patents the market opens to biosimilar versions of these products.

Biosimilars: it is not as simple as cost alone

Biosimilars/Research | Posted 29/07/2009

Biosimilars or follow-on biologics (FOBs) are biopharmaceuticals that, unlike small molecule generic products, are copies of larger, much more complex proteins. As such, data generated from one biopharmaceutical cannot be extrapolated to another. Unlike small molecule generics, FOBs require a full developmental programme, albeit smaller than for an originator product. This has been recognized by European regulatory authorities and it is becoming clear that accelerated processes for FOB marketing approval are not feasible.

Biosimilars as effective and safe as expensive biologicals

Biosimilars/News | Posted 29/07/2009

Views on biosimilars: Genentech

Biosimilars/News | Posted 29/07/2009

Genentech has put a clear position on biosimilars on its website. The company explains that the terms ‘biosimilar’ or ‘follow-on biologic’ refer to products that are marketed after expiration of patents, which are claimed to have similar properties to existing biological products. Due to the complexity of biologicals, a product can only be made that is similar, but not identical.

US biosimilars bill with competition after just five years

Biosimilars/News | Posted 29/07/2009

Key issues with biosimilars: impact on patient safety

Biosimilars/Research | Posted 06/07/2009

The primary safety concern for biosimilar agents is their potential immunogenicity. Using biopharmaceuticals to replace endogenous proteins that may be present at insufficient concentrations carries the serious risk of stimulating the immune system to develop anti-product antibodies (Abs), which may cross-react with endogenous protein.

What physicians need to know about biosimilars

Biosimilars/Research | Posted 06/07/2009

Physicians should become aware of potential differences between biopharmaceuticals (biologicals) and their generic versions (called biosimilars in the EU and follow-on protein products in the US) that will soon enter the market, and that the impact on safety and efficacy is critical for patient safety. “Healthcare professionals need to understand the critical issues surrounding the use of biosimilars to make informed treatment decisions”, states Professor Huub Schellekens in Biosimilar therapeutics – what do we need to consider in NDT Plus. 2009;2(Suppl 1):i27-i36.
