European Regulatory Framework and General Path to Market for ATMPs

Article

Applied Clinical Trials

Dave Li explores the current information on the commercialization of advanced therapy medicinal products.

This article aims to organize current information on the commercialization of advanced therapy medicinal products (ATMPs) and provides a brief overview of requirements for registration and descriptions of essential data elements leading to marketing authorization (MA) to serve as a practical approach for bringing the state-of-the-art research in ATMPs to clinical application.

ATMPs are classified as nucleic acid-based product (Gene Therapy Medicinal Product, GTMP), cell-based product (Somatic Cell Therapy Medicinal Product, SCTMP), and tissue-based (Tissue Engineered Product, TEP). It should be noted that ATMPs, GTMP in particular, are also classified as genetic modifying organism (GMO) either in the framework of deliberate release or contained use, which require environmental risk assessment (ERA) before filing a clinical trial application and/or initiating study. In addition, the pharmacology of ATMPs is characterized by distinct biological features with respect to their starting materials and specific constructs which call for special attention in trial design and pre-clinical and clinical measurement. 

 

1.   Legal and regulatory framework 

In the EU, the legal and regulatory framework for human medicines promotes unified scientific and technical standards to ensure public health protection and the quality, safety and efficacy of investigational medicinal products (IMPs) for human use.1 It requires a marketing authorization by experienced authorities before being placed on the market.A medicinal product for humans may be authorized either by the European Commission through the centralized procedure or by national competent authorities through a mutually recognized, decentralized or national procedure1-2 in the case of marketing authorization of ATMPs. It is a concerted effort between the EMA and national competent authority and other relevant government agencies at the national level of the member state involved in approval of clinical trial application (CTA) and GMO assessment.

A series of legislations have been developed over the past few decades, and they are evolving with the progressive harmonization of requirements for marketing authorization to be granted along with post-marketing monitoring and other implementations.A legal and regulatory framework has been put into place to govern the product development for ATMPs. The legal and regulatory framework is hierarchical and is organized in three levels:

  • Legislation
    All EU legislation including regulations and directives in the area of medicinal products for human use is compiled in Volume 1 of "The Rules Governing Medicinal Products in the European Union."

    The requirements and procedures for marketing authorization, as well as the rules for monitoring authorized products, are primarily stipulated in Directive 2001/83/EC and in Regulation (EC) No 726/2004.  The Table 1 of Appendix lists relevant legislations in regulation and directive.1
     

  • Explanation and guideline
    To facilitate the interpretation of the legislation and its uniform application across the EU, a series of guidelines of regulatory procedures and scientific requirements have been developed. A detailed explanation of the marketing authorization procedures and other regulatory guidance is contained in volume 2of "The Rules Governing Medicinal Products in the European Union"  (Notice to Applicants).  (https://ec.europa.eu/health/documents/eudralex/vol-2_en)  The Table 2 of Appendix lists relevant legislations in guidance.
     

  • Scientific and procedural advice
    In general, product or development specific advices can be classified into two categories, namely scientific and procedural. Specific feedback related to a product under development can be obtained through interactions with the regulatory authorities. In fact, competent authorities also suggest it would be helpful for clinical development through a structured process of exchanges of information and conversations in planning stage. Thereby, the competent authorities encourage and welcome early communications and interactions during the product life cycle for scientific and procedural advice with respect to product specific issues and questions. 

2.     Regulatory requirements

EU legislation provides for common rules for conducting clinical trials to test the safety and efficacy of medicines under controlled conditions in the EU. Various rules have also been adopted to address the particularities of certain types of medicinal products and the promotion of research in areas of ATMPs as intended use for rare disease, pediatric patients. The ATMPs cover three types of medicines for human use including somatic cell medicine, gene therapy medicine, and tissue-engineering medicine which is a technical, not mechanistic, scheme in classification.1

The authorization of the ATMPs builds on comprehensive data requirements from structured and stepwise evaluations of quality, safety and efficacy, to ensure that innovative medicinal products under development for human use are of acceptable quality with a favorable benefit-risk profile that can change the natural history of intended human diseases. 1

1)   Quality evaluation

When applying for marketing authorization, companies must provide evidence demonstrating that the product is of sound quality. This is assessed in accordance with criteria set out in EU legislation (Annex 1 of Directive 2001/83/EC and guidelines (EudraLex Volume 3).1

The quality evaluations are carried out based on a set of rules and good practice guidelines that provide safeguards against deviation from product specifications and inappropriate production and distribution practices, including source materials and testing and release criteria. Further guidance on quality is provided in EudraLex - Volume 4, and the key elements are shown in Table 2.

2)   Safety and efficacy evaluation

The safety and efficacy of medicines are evaluated through a series of clinical studies in phases. For investigational medicines, sponsors are required to demonstrate safety and efficacy through experimental data and by providing agreeable interpretations of the clinical trials.1-3

Safety and efficacy continue to be monitored after marketing authorization through pharmacovigilance activities and in reviews of the benefit-risk data in a larger patient population.1

3.    General path to market

The data on the safety and efficacy of investigational ATMPs will be assessed by the competent authorities before a product receives marketing authorization. For centrally authorized products of ATMPs, the assessment is carried out by the Commission of Advanced Therapies (CAT) of the European Medicines Agency (EMA) even though the approval of the clinical trial application (CTA of ATMPs) is the responsibility of the national competent authority (NCA) of a member state. The Committee for Medicinal Products for Human Use (CHMP) falls under the EMA and is responsible for reviewing IMPs for human use. This committee works closely with CAT on MAA of ATMP as a higher authority for ensuring the quality evaluation of MAA of ATMP. 

https://ec.europa.eu/health/authorisation-procedures-centralised_en. Some critical questions should be addressed before preparing a clinical development plan (Table 1)2.

  • Classification and certification

    Classification is carried out by the EMA, which makes recommendations with EC in 60 days. ATMPs are a product category with substantially modified starting materials of DNA, cells and tissues and their mode of action is attributable to the substantial modifications from production on an industrial scale. It may be helpful for certain ATMPs, especially in the SCTMPs area. It will offer ascertainment on the regulatory path and necessary guidance for both documentation and data sets as needed for a MAA.
    https://www.ema.europa.eu/en/human-regulatory/marketing-authorisation/advanced-therapies/advanced-therapy-classification

  •  Marketing authorization application (MAA)
    CAT is one of the seven committees in EMA which oversees the review process for MAA of ATMPs. It makes recommendations to CHMP regarding MA. If CHMP concurs with CAT, it generates a favorable opinion to EC, which grants the MA. It usually takes 277 procedural days from MAA to final decision. 

4.   Other important considerations

  • GMOs

    ATMPs are also regulated under the current GMO regulations either in the framework of deliberate release (Directive 2001/18/EC) or contained use (Directive 2009/41/EC) which requires environmental and health risk assessment before or in parallel to the clinical trial application. The directives being implemented in the member states are varied in practice with significant procedural differences. For deliberate release, formal consent is always required before activity may start and only higher classes of risk categories pre-approval. In general, ATMPs may likely be subject to contained use with the understanding that there is no intention to release the IMPs, and the activities in clinical trials are not expected to release the IMPs into the environment. In addition, Directive 2001/18/EC focuses on the deliberate release of genetically modified plants and agricultural products, not IMPs.

    On the operational level, it must follow the specific requirements of risk assessment with respect to deliberate release or contained use in each member state. Shedding and transmission studies should be carried out accordingly, as the basis for determining the environmental risk and effects on human health. The EMA provides guidelines for conducting the risk assessment and lists specific scientific requirements for the exercise. (https://www.ema.europa.eu/en/documents/scientific-guideline/guideline-environmental-risk-assessments-medicinal-products-consisting-containing-genetically_en.pdf and https://www.ema.europa.eu/en/documents/scientific-guideline/draft-guideline-scientific-requirements-environmental-risk-assessment-gene-therapy-medicinal_en.pdf).

    While the review of ATMPs is a centralized procedure by CAT of EMA, however, CTA and GMO assessment typically occurred independently at the national level. Central to the GMO assessment is environment risk analysis, using either a framework of contained use or deliberate release. The contained use is defined by the risk class of the GMOs and protective barriers are designed to limit the unexpected exposure of the potentially infective agents and harmful effects. The deliberate release is, in contrast, in consideration of less restrictive measures to protect or limit the public from exposure in the general environment.4 

    The methodology for risk assessment is similar for the contained use and the deliberate release; including steps of hazard identification, characterization, exposure assessment and risk assessment. The requirements for the data and information regarding the IMPs and the environment may be of greater burden in performing the risk analysis to the sponsor for deliberate release, since the containment procedures are less stringent.
     

  • Orphan medicinal product
    If a target disorder of unmet medical needs with prevalence of less than 5 per 10,000 population, an ATMP may be qualified as orphan medicinal product.2 
     

  • Pediatric study plan
    A Pediatric Investigational Plan (PIP) is required if ATMPs are indicated for affected children before the completion of the Phase 1 study for the ATMPs, which is intended for pediatric patients.2
