Research on clinical trial issues for biosimilars

Period: September to December 2012 

In order to demonstrate comparability between a biosimilar and its reference product, EMA recommends that the clinical trial should make it possible to detect a difference between the biosimilar and reference product. In most cases, this means that a two-arm clinical trial design (reference biological and biosimilar) in a small group of homogenous patients may be used. If the two arms of the trial produce similar results, then the biosimilar can be approved.

Quality, similarity and safety of biosimilars

An abbreviated pathway for the approval of biosimilars was implemented in the EU in 2005. Despite biosimilars being available in Europe for more than seven years, physicians still have concerns about the use of biosimilars. Members and experts of the Working Party on Similar Biologic Medicinal Products of the European Medicines Agency (EMA) highlight what physicians need to know to make informed and appropriate treatment choices for their patients [1].

The results demonstrated the comparable pharmacokinetics and safety of CT-P6 to the reference drug.

Biosimilars applications under review by EMA – 2013 Q1

Last update: 12 April 2013 

The European Medicines Agency (EMA) is the body responsible for approval of biosimilars within the EU. A legal framework for approving biosimilars was established in 2003. Approval of biosimilars is based on an abbreviated registration process, which allows biosimilars manufacturers to provide a reduced package of information compared to originator drugs, provided they can prove ‘similarity’ to the originator or ‘reference drug’.

Lonza/Teva biosimilar pact in jeopardy

Switzerland-based API producer and custom manufacturing organization Lonza is reviewing whether it is still worth investing in its joint venture for biosimilars with Israeli generics giant Teva Pharmaceutical Industries (Teva).

Research on biosimilars in anaemia and diabetes

Period: September to December 2012 

The use of biological medicines has been life-changing for many patients suffering with anaemia and diabetes. With the expiration of patents on these biologicals the possibility of patients gaining access to lower cost biosimilar alternatives to these extremely effective, but costly, medicines becomes a real possibility.

Biosimilars in rheumatology

Patents on key biological medicines used in rheumatology will expire soon. The European Medicines Agency’s (EMA’s) finalized guidelines on biosimilar monoclonal antibodies (mAbs) came into effect on 1 December 2012. Both of these facts mean that rheumatologists can expect to be exposed to biosimilars of the medicines they routinely use in the near future.

Sandoz’s biosimilar rituximab on track

The development of a biosimilar version of Rituxan (rituximab) is proceeding as planned, Sandoz’s Global Head, Mr Jeff George told Bloomberg.

How are biosimilars special

Despite biosimilars being around in the EU since 2006 physicians are still often reluctant to prescribe them. Members and experts of the Working Party on Similar Biologic Medicinal Products of the European Medicines Agency (EMA) highlight what physicians need to know to make informed and appropriate treatment choices for their patients [1].

Pharma companies sue EMA to block release of data

US-based biotech companies AbbVie and InterMune have both sued EMA in a bid to block publication of clinical trial data for their drugs.

Research on biosimilars in rheumatology

Period: September to December 2012 

Over the past decade, the availability of targeted biological therapies has revolutionized the treatment of rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. However, the significant cost of these biologicals is often prohibitive and limits universal access to these effective therapeutic agents. Whereas generic drug equivalents are commercially available for many small-molecule medications, such lower cost alternatives to targeted biological therapies are not yet available in the US or the EU.  The first biological therapeutics in rheumatology is now approaching patent expiration and biosimilars are now in randomized controlled trials. This means that cheaper biosimilars for the treatment of rheumatic diseases are likely to enter the market in the near future, increasing patient access to these life-changing treatments.

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).

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
