EU Biosimilar philosophy
• Apply scientific principles
• Use most sensitive methods / studies to
show differences
• Reduce non-clinical / clinical data
requirements where appropriate
• Develop EU network and facilitate global
evolution of biosimilar framework

How to realise biosimilar’s full potential: Regulator’s view
Overarching Guideline
Main changes:
• Definition of biosimilar and scope of biologicals covered
• How to manage: improved efficacy or safety
• Clarification regarding possibility to gain authorisation based on a PK
comparative study (minimal clinical data)
• Choice of reference medicinal product (global development)
10
How to realise biosimilar’s full potential: Regulator’s view
Proposed Biosimilar Definition
A biosimilar is a biological medicinal product containing a version
of the active substance of an already authorised original
biological medicinal product (reference medicinal product) (RP).
A biosimilar demonstrates similarity to the reference medicinal
product in terms of quality characteristics, biological activity,
safety and efficacy based on a comprehensive comparability
exercise.
11
How to realise biosimilar’s full potential: Regulator’s view
Improved efficacy / safety
 Intended changes to improve efficacy are not compatible with
the biosimilarity approach.
 Differences which could have a safety advantage (e.g., lower
levels of impurities or reduced immunogenicity) should be
explained but may not preclude biosimilarity.
12
How to realise biosimilar’s full potential: Regulator’s view
Tailored development programme
In specific circumstances, e.g. for structurally more
simple biological medicinal products, a comparative
clinical efficacy study may not be necessary
• if similarity of physicochemical characteristics and biological
activity/potency of the biosimilar and the reference product
can be convincingly shown and similar efficacy and safety can
clearly be deduced from these data and comparative PK data.
• such an approach may have to be supported by additional
data, for example in vitro and/or clinical PD data from a
comprehensive comparative PD fingerprint approach.
13
How to realise biosimilar’s full potential: Regulator’s view
Choice of Reference Product (RP)
Facilitation of global development
 A non EEA-authorized version of the RP may be used for certain
clinical and in vivo non-clinical studies (where needed) if
- authorisation based on similar regulatory standards
- representative of the RP in the EEA
 Bridging data will typically include
- 3-way quality comparison (e.g., structural / functional data)
And may include
- 3-way PK and/or PD comparison
14
How to realise biosimilar’s full potential: Regulator’s view
General Non-clinical / Clinical Guideline
Main changes:
• Risk-based approach: extent and nature of studies dependent on
– product complexity
– ability to characterise at quality level
– differences at quality level (active substance and formulation (excipients,
impurities))
• Non-clinical : step-wise approach (in vitro, need for in vivo, in vivo)
• Clinical: PD markers and surrogate endpoints, safety, study design to
test immunogenicity, extrapolation of indication
15
How to realise biosimilar’s full potential: Regulator’s view
General Quality Guideline
Main changes, elaboration / clarification of:
• Quality target product profile (QTPP)
• Evolution of quality profile through life-cycles
• Comparability at the level of the finished product
• Amino acid sequence expected to be the same as reference product
• Additional testing expected for monoclonal antibodies
• Different expression system

•
Remsima (duplicate Inflectra) : first biosimilar mAbs to be approved in
Europe. European Commission Decision – 10th September 2013.
Active substance: INN infliximab
Reference product Remicade (authorised 1999).

Remsima - Learnings
•Extensive comparability exercise: quality and non-clinical (in-vitro).
This provided robust assurance on clinical performance and the
extrapolation of indications.
•Difference in quality profile - reduced afucosylation, translating into a
lower binding affinity towards specific FcγRIIIa receptors→ lower ADCC
activity ? Resolved by extended testing: physicochemical / bioactivity
and consideration of mechanism of action.

INN Aspects
•
EMA uses INN according to WHO policy
•
Biosimilar can use Reference Product INN
- EMA: robust assessment of biosimilarity
•
WHO Consultation – 2006 / 2013
•
What can be expected from INN ?
- WHO Biological Qualifier
• Coding of active substance in biosimilar
- TGA Policy :

For further details on the discussion at the 57th Consultation on
INN
for Pharmaceutical Substances in October 2013,
please see the Executive Summary:
http://www.who.int/medicines/services/inn/57th_Executive_Summary.pdf
International Pharmaceutical Regulators Forum - IPRF
The IPRF will meet initially in conjunction with ICH Steering Committee meetings. Switzerland chair, Japan co-chair.
The first goal is to enable all parties to identify new approaches and specific best practices, and develop smart strategies for dealing with the challenges of the
globalization of the pharmaceutical industry. The second goal is to provide a global overview of the different regulatory developments at national and international
level and enable open sharing of information and ideas among regulatory leaders with hands-on operational responsibilities. This information sharing will allow the
forum participants to discuss issues at an actionable level of detail. The third goal is to support international regulatory cooperation in areas which are not covered
by existing initiatives.
