Advanced Therapy Medicinal Products

On 13 December 2019, the European Medicines Agency (“EMA”) published a Questions and Answers document (“Q&A”) providing guidance on the conduct of comparability exercise for advanced therapy medicinal products (“ATMPs”). The Q&A addresses various regulatory questions that arise in situations in which companies developing or marketing ATMPs introduce changes to the manufacturing process and need to generate related comparability data.

Background

EMA’s experience suggests that changes to the manufacturing of ATMPs are “frequent” and even more so in the development of the medicinal product. These changes need, however, to be introduced in accordance with the Good Manufacturing Practices (“GMP”). Moreover, the changes may require a variation of the marketing authorisation for authorised ATMPs or substantial amendments to the clinical trial protocol for ATMPs used in clinical trials.

In addition, the changes to the manufacturing of the ATMP must be supported by the data generated in a comparability exercise. This exercise should focus on the characteristics of the ATMP prior and after the introduction of the manufacturing change. This is valid for both investigational ATMPs and authorised ATMPs.

The position of the EMA is that changes to the manufacturing of the ATMP should not undermine or impact adversely the quality, efficacy or safety of the medicinal product or the related risk-benefit balance. The objective of the comparability exercise is to facilitate the assessment and demonstration of this.

As reported in our previous post, at the end of last year, the European Commission published a draft amendment to Regulation No 847/2000 regarding the concept of “similar medicinal product” for the purposes of the Orphan Medicinal Products Regulation. Last week, the final Regulation was published: Regulation (EU) 2018/781. The new Regulation

On 22 November 2017, the European Commission adopted new guidelines on Good Manufacturing Practice (GMP) specific to Advanced Therapy Medicinal Products (ATMPs). ATMP manufacturers must ensure compliance with these guidelines no later than 22 May 2018.

The guidelines seek to reflect the rapid technological and medical advancements being made in the field of ATMPs (i.e. gene therapies, somatic cell therapies and tissue engineered products), such as decentralised manufacturing for autologous products, automated production, outsourced reconstitution, and gene editing technologies such as CRISPR and immunomodulators. Currently, these new technologies must comply with the general GMP guidelines set out in Volume 4 of The rules governing medicinal products in the European Union. However, these products are often developed in an academic or hospital setting under quality systems different to those typically required for the manufacture of conventional medicinal products.

The European Commission has finally published the draft amendment to Regulation No 847/2000 regarding the concept of “similar medicinal product” for the purposes of the Orphan Medicinal Products Regulation. A key incentive of this Regulation is the ten-year market exclusivity that protects an orphan medicinal product, whereby national competent authorities shall not accept an application for authorisation, or grant an authorisation, or accept an application to extend an existing authorisation, “for the same therapeutic indication, in respect of a similar medicinal product” as the orphan product. Regulation 847/2000 defines “similar medicinal product” in this context, and sets out a number of examples of what kind of products will be similar.

Following a consultation last year, the Commission intends to make changes to the 17-year-old text to account for the rise of cell therapies and other advanced therapy medicinal products, the nature of which do not fit neatly into the current definitions.
