EMA responds to questions over biosimilar comparability

Biosimilars/Research | Posted 07/09/2012

EMA has responded to questions regarding its comprehensive biosimilar regulatory pathway. The pathway, which includes the need for new clinical trials and comparability studies that demonstrate quality, efficacy, and safety, has been accused of proving to be a barrier for the development of clinically superior compounds [1].

‘Similar biologics’ approved and marketed in India

Last update: 15 February 2018

There have been established guidelines for approving generic versions of small molecule chemical drugs in India for some time already. However, no specific guidelines for ‘similar biologics’, as the Indian regulatory authorities call these products, existed in India until 2012. This has been the case despite the fact that the requirements for granting regulatory approval for such ‘similar biologics’ required more data than for a simple generic drug application [1].

Patients and biosimilar interchangeability

Biosimilars/Research | Posted 07/09/2012

Biopharmaceuticals or biologicals are complex medicines produced by living cells. Copies of approved biologicals have been introduced recently. Because of their intrinsic complexity such copies are similar but not identical to the reference medicine and are therefore called ‘biosimilars’. Approval of biosimilars requires a full quality analysis including a detailed comparison to the reference whereas non-clinical and clinical evaluations are less extensive.

Investigating G-CSF biosimilars approved in Europe

Biosimilars/Research | Posted 24/08/2012

A life-threatening complication for patients undergoing chemotherapy is febrile neutropenia, involving a loss of neutrophils (white blood cells) and fever. Granulocyte colony-stimulating factors (G-CSFs) are growth factors which are used to restore neutrophil production.

Is pegfilgrastim superior to filgrastim for the treatment of febrile neutropenia?

Biosimilars/Research | Posted 17/08/2012

A study to compare the cost-efficiency of three different recombinant granulocyte colony-stimulating factors (G-CSFs) for the treatment of chemotherapy-induced febrile neutropenia assumes that they are of comparable efficacy. But how solid is the evidence for this assumption? A study by Professor Matti Aapro and co-authors explores the available evidence regarding efficacy for the three G-CSFs, filgrastim (Neupogen, Amgen), pegfilgrastim (Neulasta, Amgen) and a filgrastim biosimilar (Zarzio, Sandoz/Novartis) and concludes that evidence behind previous claims of superiority for pegfilgrastim is ‘similar’ and ‘open to question’ [1]. Thus, originator and biosimilar filgrastim appear to be holding ground in the efficacy stakes.

Testing for unwanted immunogenicity from biologicals

Immunogenicity caused by biologicals, both originator and biosimilar, is an important issue that was raised by Dr Wadhwa from the National Institute for Biological Standards and Control [1].

Biotechnology company iBio, self-professed leader in the plant-made pharmaceutical field, and GE Healthcare, the health business of General Electric, announced on 26 July 2012 a new global alliance to commercialise plant-based technologies for the manufacture of biologicals and vaccines.

FDA urged to exclude plasma protein therapies from biosimilar pathway

Biosimilars/General | Posted 03/08/2012

FDA is being lobbied by patient and industry groups to exclude plasma protein therapies from its pathway for the approval of biosimilars. FDA has a mandate to create a new abbreviated process for the approval of biosimilars under the Biologics Price Competition and Innovation Act of 2009, which was part of the new healthcare reform law passed in March 2010 [1]. This potentially brings cheaper products to market sooner, and so increases the availability of affordable health care. However, it also means that manufacturers applying for approval for new biosimilars may be able to skip clinical testing if they can demonstrate sufficient similarity with reference products.

Deal struck over development of Herceptin biosimilar

Biosimilars/News | Posted 03/08/2012

Netherlands-based biopharmaceutical company Synthon announced on 18 July 2012 that it has entered into a global licensing agreement with Amgen and Watson Pharmaceuticals for the clinical development and testing of biosimilar trastuzumab as an alternative to Roche’s blockbuster anticancer agent Herceptin. The deal follows the results of a phase I trial reported on 22 March 2012 showing bioequivalence between Synthon’s trastuzumab and Herceptin [1].

Small molecule versus biological drugs

Biosimilars/Research | Posted 29/06/2012

Biological drugs are large and complex, often consisting of heterogeneous mixtures. They are generally made in genetically engineered cells that impose their own variabilities–in post-translation modifications such as glycosylation–on the processes used to make such drugs.
