The documents under question include guidelines on quality, clinical efficacy and safety, non-clinical, and also include two of the European Medicines Agency’s (EMA) newly revised overarching guidelines on biosimilars.

The overarching guideline on similar biological products was finalized on 23 October 2014 and came into effect in Europe on 30 April 2015 [1]. EMA’s guideline on non-clinical and clinical issues of biosimilars was finalized on 18 December 2014 and comes into effect in Europe on 1 July 2015 [2].

Guideline on similar biological medicinal products 
CHMP/437/04 Rev 1
Effective date: 30 April 2015
www.ema.europa.eu/docs/en_GB/document_library/Scientific_guideline/2014/10/WC500176768.pdf

Guideline on similar biological medicinal products containing biotechnology-derived proteins as active substances: non-clinical and clinical issues
EMEA/CHMP/BMWP/42832/2005 Rev1
Effective date: 1 July 2015
www.ema.europa.eu/docs/en_GB/document_library/Scientific_guideline/2015/01/WC500180219.pdf

The guideline on similar biological medicinal products outlines the general principles to be applied for biosimilars and describes and addresses the application of the biosimilar approach, the choice of the reference product and the principles for establishing biosimilarity. The main change brought by this new guidance is the possibility for biosimilars developers to use a comparator authorized outside the European Economic Area (EEA) during the clinical investigation of a biosimilar.

The non-clinical and clinical biosimilars guideline addresses the non-clinical pharmaco-toxicological assessment, as well as the requirements for pharmacokinetic, pharmacodynamic and efficacy studies. The section on clinical safety and pharmacovigilance addresses clinical safety studies, including immunogenicity, as well as the risk management plan.

TGA is asking for comments on the proposed adoption or non-adoption of the EU guidelines, and particularly as to whether stakeholders support the proposed adoption of the guidelines.

Feedback on the guidelines can be submitted to TGA until 22 May 2015 via post or email (euguidelines@tga.gov.au).

TGA has already adopted many of EMA’s guidelines for biosimilars, as well as publishing its own guidance on the evaluation of biosimilars [3].
