Pro-generics policies and the backlog in medicines registration in South Africa: implications for access to essential and affordable medicines Comment by Ernest Schay, Bayer Thank you for this very interesting article. From a veterinary medicine perspective, it would certainly explain why such medicines are also experiencing a delay, as veterinary medicines use the same P & A (Pharmaceutical…

Published on 11 December 2015

Fourth and final issue of GaBI Journal’s fourth volume

This last issue of 2015 starts with a Commentary by Drs Christoph Baumgärtel and Brian Godman concerning the approval of generic versions of narrow therapeutic margin products; including immunosuppressant drugs. The authors explain why they find concerns that have been raised by some clinicians concerning the bioavailability margins needed for approval of narrow therapeutic drugs…

Abstract: With many biosimilars being approved around the world, there is an urgent need for clear guidelines on establishing biosimilarity and on approving subsequent extrapolation. The balance between clinical studies and analytics in establishing and confirming biosimilarity are discussed in this paper. Submitted: 28 July 2015; Revised: 15 August 2015; Accepted: 16 August 2015; Published…

Abstract: Biosimilars have been approved in Europe since 2006. With patents on originator biologicals expiring and ever-tightening healthcare budgets biosimilars are likely to take an increasing share of the biologicals market. In light of these facts, this article gives estimated patent expiry dates for just some of the best-selling biologicals. Submitted: 19 November 2015; Revised:…

Introduction: Similar biotherapeutic products (SBPs or biosimilars) include a rapidly expanding number of therapeutic products worldwide. However, agreement about the best practices for their regulation are lacking in many countries including in the Middle East and North Africa (MENA). Methods: The first MENA educational workshop on SBPs was held in Dubai, UAE on 1 September…

Submitted: 6 October 2015; Revised: 10 October 2015; Accepted: 12 October 2015; Published online first: 26 October 2015 The most critical safety concern relating to biologicals (including biosimilars) is immunogenicity. This is especially important for monoclonal antibody (mAb) biologicals, which are large molecules with complex structures and functions and which represent the largest class of…

Abstract: Hybridomas were developed in 1975 as a stable platform for creating monoclonal antibodies (mAbs). Over the past 40 years, hybridomas have been a leading platform for creating mAbs, yet of the 50 commercial mAbs approved for sale by the US Food and Drug Administration (FDA), only 18 are produced using hybridomas. Of the remainder,…

Author byline as per print journal: Christoph Baumgärtel, MD, MSc; Brian Godman, BSc, PhD Abstract: Stricter bioequivalence criteria are in place for generics where there are narrow therapeutic indexes such as generic immunosuppressives, enhancing their acceptance despite limited published studies. No serious issues have been reported to date with generic ciclosporin despite being on the market…

Abstract: As per regulatory requirements, biosimilar drugs must show high similarity to their reference product in quality, preclinical and clinical tests. It is by these means that biosimilars are considered to be safe and efficacious. In India, any major deviation(s) from science-based principles in the manufacturing of a recombinant DNA-derived therapeutic biological product leads to…
