Biosimilars
Oncobiologics and Viropro make biosimilar deal
US-based Oncobiologics and monoclonal antibody developer Viropro announced on 25 February 2013 that they had signed a biosimilar collaboration agreement between the two companies.
Assessment of interchangeability under the BPCI Act
The Biologics Price Competition and Innovation (BPCI) Act gives FDA the authority to designate a biosimilar as interchangeable with its reference product. This means that the biosimilar may be substituted for the originator product by the pharmacist without reference to the prescribing physician [1]. The criteria for establishing interchangeability of biosimilars, despite FDA issuing three draft guidance documents, are still not clear [2].
Amgen’s response to biosimilar substitution legislation in US
Amgen, in a statement issued on 1 February 2013, has hit back at accusations that the biotech giant is attempting to limit the uptake of biosimilars in the US by backing state bills, which constrain the use of biosimilars.
The ethics of biosimilars
Biosimilars in the EU have to undergo a strictly regulated comparability exercise against the reference medicinal product on the physicochemical, analytical, functional, non-clinical and clinical level. Only if a biosimilar is a close copy of the reference medicine will it be approved as a biosimilar [1]. Despite this fact, however, ethical issues have been raised on the use of granulocyte colony-stimulating factor (G-CSF, filgrastim) in healthy volunteers by the European Group for Blood and Marrow Transplantation (EBMT) and the World Marrow Donor Association (WMDA).
Merck makes biosimilars deal with Samsung Bioepis
Pharma Giant Merck announced on 20 February 2013 that it had made a deal to develop and commercialize biosimilars with Samsung Bioepis.
Medicines spending in Brazil
The Brazilian pharmaceutical market is the third largest in the Americas region, behind the US and Canada; it ranks first in the Latin American region. Pharmaceutical demand will continue to rise, fuelled by increasing disposable income. Despite this positive outlook, the trade deficit in Brazil grew from US$700 million at the end of the 1980s to a cumulative US$7.13 billion in 2008. In 2008 alone, Brazil imported US$1.4 billion in vaccines, serum and blood products, while exporting US$37 million in medicinal products with low added value [1].
Biosimilars to replace 70% of chemical drugs
Biosimilars will replace some 70% of global chemical drugs over the next couple of decades, according to industry experts. This replacement will occur due to the better safety profiles of biosimilars compared to chemical drugs and the fact that many originator biologicals will lose their patent protection in the coming years, according to Mr Appaji, Director General of Pharmaceuticals Export Promotion Council of India (Pharmexcil).
AMAC and GPhA hit back at Big Pharma over biosimilars
The Association of Mature American Citizens (AMAC) and the Generic Pharmaceutical Association (GPhA) have reacted strongly to the actions by Amgen and Genentech, which aim to make it more difficult for patients to get access to biosimilar medicines [1].
Biologicals boom
Researchers predict that the present list of top 10 blockbuster drugs will change dramatically by 2014. The predictions are that by 2014 biological drugs will topple the present market leaders Pfizer’s Lipitor (atorvastatin) and Sanofi’s Plavix (clopidogrel), both of which are small molecule chemical entities [1].
Biotech firms try to limit biosimilar substitution in US
FDA is still to approve a biosimilar and has yet to issue final guidelines outlining the regulatory requirements for approval of a biosimilar in the US.
