Overview
Introduction
The drive for increased cost savings by healthcare providers is increasing the focus on boosting the biosimilar market. With a regulatory approval pathway in place in Europe and substantial guidelines to support biosimilar development, the European biosimilars market is significantly more advanced than the US, where plans for a biosimilar regulatory approval pathway have stalled.
Scope
*Introduction to why biosimilars development is being pushed in Europe and the US *In-depth analysis of the US and European biosimilar regulatory environment *Overview of the success of biosimilar approvals in the US and European markets *Identification of future trends shaping biosimilar regulatory environment evolution
Highlights
Although the FDA was relatively pro-biosimilars from 1999-2004, the release of regulatory guidelines for biosimilars has stalled significantly since the resignation of Commissioner McClellan; furthermore, the FDA’s switch to a stance of issuing broad biosimilars guidance first will require Congress action, delaying biosimilar launches further.
The European regulatory environment is considerably more favorable for biosimilar developers, with the release of a range of directives and guidelines set to help guide biosimilar development; however, more clarity is needed to clear up ambiguities in legislation and more strongly shape biosimilar approvals.
In the future, the evolution of the biosimilars environment will largely depend on whether the pro-biosimilars or the anti-biosimilars faction has greatest influence over the regulatory authorities; in the US, the pro-innovator biologics faction is currently more powerful, while in Europe, the pro-biosimilars faction has had greater success.

CHAPTER 2 OVERVIEW OF BIOSIMILARS AND HOW REGULATORY ISSUES IMPACT THE MARKET
The potential for cost savings drives the development of a biosimilars regulatory approval pathway
Recombinant proteins are the key target for biosimilar developers
The complexity of the biosimilars regulatory environment is a key factor restricting biosimilars developers
CHAPTER 3 THE POWER BALANCE BETWEEN PRO-BIOSIMILARS AND ANTI-BIOSIMILARS SHAPES MARKET EVOLUTION
The current situation: the US lags further behind as the issue becomes more politically charged
Currently, the European environment is more pro-biosimilars than the US
The stronger position for innovator biologics companies in the US means that greater political pressure is required to support the development of a biosimilars regulatory approval pathway
Whoever wins the battle between the pro-biosimilars faction and the anti-biosimilars faction will significantly impact the way that the biosimilars market evolves in the US and Europe
There are significant difficulties with demonstrating comparability
Why is comparability such a problem?
Comparability is therefore a key issue for biosimilars, and stringent requirements boost development costs
The importance of choosing the right reference product to demonstrate comparability
Although there are extensive comparability requirements, it is important that biosimilar developers seek guidance from European and US regulatory bodies
Problems with establishing ‘sameness’ means that generic substitution is unlikely to be relevant for biosimilars
Does the process make the product? And if so, are biosimilar developers asking regulatory bodies to act illegally?
In the past, innovator drug companies have been happy to support the argument that biologics manufactured in entirely different ways are the same as the innovator drug
It is becoming easier to demonstrate comparability
Safety remains the key to determining comparability
CHAPTER 4 THE REGULATORY ENVIRONMENT FOR BIOSIMILARS IN THE US
Introduction to the approval process for generics in the US and how biosimilar approvals fit into this process
Key events shaping the development of a biosimilars approval pathway: the FDA changes tack in 2004, delaying biosimilars market entry
From 2001 to 2004, the FDA prioritized developing guidance for biosimilars, despite attacks from innovator developers
The resignation of McClellan in 2004 led to delays in the development of guidance for biosimilars
FDA workshops do little to accelerate progress, while the development of a regulatory pathway stalls
Biosimilar developers turn to the USP to help find a way to accelerate the development of a regulatory pathway for biosimilars of NDA biologics by characterizing comparability between biosimilars and innovator biologics
Innovator biologics companies retaliate by issuing a white paper, hoping to stall the process further
Despite significant resistance from innovator biologics companies, some progress in the development of a biosimilar regulatory process is now being made in the US
Hatch and Waxman urge the FDA to provide guidelines on approvals of biosimilars of NDA biologics
Citizen petition lobbies the FDA to provide requirements for the approval of biosimilar versions of NDA biologics
The ‘Access to Life-Saving Medicine’ Act represents the largest stride in developing a biosimilars approval pathway
While progress in developing a biosimilars regulatory pathway stalls, biosimilar developers are using the full submission pathway
The battle to get Omnitrope approved: the biosimilar submission and approval record at the FDA
Is Omnitrope really the first follow-on biologic to be approved?
Omnitrope’s approval in the US: it may not have been the first follow-on biologic approved under Section 505(b)(2) but it has created the greatest interest
CHAPTER 5 THE REGULATORY ENVIRONMENT FOR BIOSIMILARS IN EUROPE
A range of directives and guidelines are used to shape the biosimilar regulatory environment in Europe
Overarching directives and guidelines shaping biosimilar approvals
The Pharma Review 2001 kicks off biosimilar approval pathway discussion
Product class guidelines help to guide biosimilar approvals for the major recombinant protein classes
Comparability guidelines provide essential information on how to demonstrate comparability between biosimilars and innovator biologics
Quality guidelines developed to help innovator drugs companies get around inter-batch variability can be used by biosimilar developers to show comparability
Non-clinical and clinical issues help shape what type of data is included in the biosimilar submission dossier
Additional legislation impacting biosimilars: Directive 2004/27/EC redefines exclusivity and affirms the Bolar provision
Biosimilar submission and approval record at the EMEA: Europe has been a more favorable environment for biosimilar approvals
