Design out NeuGc, Fab glycosylation for biobetter MAbs

In an article by Dr Claire Morgan and Dr Daryl Fernandes of Ludger, published in IPI of Autumn 2009, it is shown how both the original drug manufacturers and the designers of follow-on biologics could produce biobetter monoclonal antibodies (MAbs) through glycoengineering. (see also Ludger’s GTO-QbD: Defining glycovariant biobetter MAbs, When is a glycoengineered biobetter commercially better than a biosimilar? and Strategy and tools for building glycoengineered biobetter MAbs)

Design out Gal-α(1,3)-Gal for biobetter MAbs

Strategy and tools for building glycoengineered biobetter MAbs

Ludger’s GTO-QbD: Defining glycovariant biobetter MAbs

One area of great interest to developers, copiers and improvers of therapeutic antibodies is glycosylation, since it can significantly influence the safety and efficacy profiles of the drug. In an article by Claire Morgan and Daryl Fernandes of Ludger published in IPI of Autumn 2009, it is shown how both the original drug manufacturers and the designers of follow-on biologics could produce biobetter antibodies through glycoengineering. In particular, they examine strategies for optimising both fragment antigen-binding (Fab) and fragment crystallisable (Fc) region glycosylation to produce monoclonal antibodies (MAbs) with improved clinical performance and better commercial profiles compared to existing drugs.

Why are there suddenly ‘biosimilars’ besides ‘biologicals’?

“Isn’t everything already complicated enough?” asked Professor Theo Dingermann of the Goethe University in Frankfurt, Germany, at the Weekend Workshop ‘Patient and Pharmaceutical Care’ of the German Union of Pharmacists Societies (Bundesvereinigung Deutscher Apothekerverbände, ABDA) held on 17–18 October 2009 in Hannover, Germany.

Biologicals and biosimilars: how can we afford them?

Demand for biological drugs is putting pressure on health budgets. Medical student, Mr Christopher Kelly and Consultant Physician, Dr Fraz Mir of the University of Cambridge, UK, examine in the British Medical Journal of 19 September 2009 why they are so expensive and what can be done to increase access.

Why is “the process the product” for biosimilars?

“Why does the manufacturing process play such a prominent role in the definition of a biosimilar?” asked Professor Theo Dingermann of the Goethe University in Frankfurt, Germany, at the Weekend Workshop ‘Patient and Pharmaceutical Care’ of the German Union of Pharmacists Societies (Bundesvereinigung Deutscher Apothekerverbände, ABDA) held on 17–18 October 2009 in Hannover, Germany.

Dingermann: “Use biosimilars, but don’t force patients”

“Thanks to the stringent examinations of EMEA, patients can trust that approved biosimilars are effective and tolerable – a reassuring remark for those who are dependent on such medicines,” said Professor Theo Dingermann of the Goethe University in Frankfurt, Germany, at the Weekend Workshop ;Patient and Pharmaceutical Care’ of the German Union of Pharmacists Societies (Bundesvereinigung Deutscher Apothekerverbände, ABDA) held on 17–18 October 2009 in Hannover, Germany.

Quality, safety and efficacy of the epoetin alfa biosimilar Binocrit compared to Erypo/Eprex

A detailed checklist on the quality, safety and efficacy assessment of biopharmaceuticals was published by Professors Irene Krämer, Roger Tredree and Arnold Vulto in the 2008 EJHP Practice article Points to consider in the evaluation of biopharmaceuticals (Eur J Hosp Pharm Prac. 2008;14(1):73-6). The checklist was then used by Dr Carsten Brockmeyer and Dr Andreas Seidl of Sandoz/Hexal for Binocrit, the results of which were published in Eur J Hosp Pharm Prac. 2009;15(2):34-40.

Rejected biosimilars: the Alpheon case

On 28 June 2006 the Committee for Medicinal Products for Human Use (CHMP) of the EMEA recommended the refusal of marketing authorisation for Alpheon (interferon alfa-2a), which was intended for the treatment of adult patients with chronic hepatitis C in combination with the antiviral medicine ribavirin (except when patients could not take this).
