European Commission (EC)

New guidance on the implementation of the regulatory requirements for medicines used under the GMO framework

Clinical trials conducted in European Union (EU) with Investigational Medicinal Products (IMP) that contain or consist of Genetically Modified Organisms (GMOs) must comply with applicable requirements under Directive 2001/18/EC ("deliberate release framework") and/or under Directive 2009/41/EC ("contained use framework") in addition to the legislation governing clinical trials. This GMO regulatory framework aims to ensure a high level of protection for human health and the environment.

Given the wide-range of gene therapies used in clinical trial over the last decade, a need has been identified for greater guidance on the implementation of the GMO regulatory framework. The document applies only to human cells genetically modified by retro/lentiviral vectors in cases where the applicant demonstrates that:

  1. there is no or negligible risk of formation of replication competent virus, and
  2. the finished product is free of residual infectious viral vector particles that are capable of being released in the environment

The document, jointly developed by the EC services and the Competent Authorities (CA) responsible for the implementation of the clinical trial legislation and those responsible for the implementation of the GMO legislation, has been endorsed by 17 European member states including Austria, Belgium, Cyprus, Czech Republic, Denmark, France, Germany, Greece, Hungary, Italy, Luxembourg, Malta, Norway, Portugal, Romania, Spain and Sweden..

The document, based on accumulated experience with the assessment of these products, includes

  • a section on “Environmental risk assessment (ERA) and data requirements” (in line with deliberate release legislation) including detail on:
    • Demonstration of absence of formation of replication competent virus,
    • Demonstration of absence of residual infectious viral vector particles in the transduced cells

This section is accompanied by an annex called “Specific ERA” designed for products intended to be used as investigational medicines. The annex demonstrates that these products have no hazards to animal health or the environment and negligible risks for human health for the relevant human hazards scenarios i.e. accidental transfer to immune incompetent individuals, erroneous administration to a different patient, donation of blood, cells, tissues or organs to immune-incompetent thirds provided that relevant control measures are implemented by the applicants.

  • a section on “Manufacturing requirements and containment levels” (in line with contained use legislation) recalling that the manufacturing of viral vectors and the ex vivo transduction of human cells with viral vectors should be performed under biosafety level (BSL) 2 but offering the possibility to downgrade to BSL 1 post transduction manufacturing activities under certain conditions.

The good practice should be read in conjunction with the common application form developed at the same time and endorsed by almost the same countries (except Czech Republic and Sweden). This common application form can be seen as a first step towards harmonization of the GMO regulatory framework between European countries and intends to standardise the type of information required.

Applicants preparing a GMO submission involving human cells genetically modified by retro/lentiviral vectors in European countries are advised to take into consideration the recommendations of this new GMO good practice guide.

Draft Guideline on “Good Clinical Practice for Advanced Therapy Medicinal Products

The new draft Guideline on Good Clinical Practice (GCP) specific to Advanced Therapy Medicinal Products (ATMP) - developed by the Commission services, the European Medicines Agency (EMA) and the expert group of the CA of the Member States – has been released for consultation. Stakeholders involved in clinical trials with ATMPs are invited to provide comment until 31 October 2018. ATMP are complex and innovative products which may pose specific challenges to the design and conduct of the clinical trials. The document – based on the current accumulated experience – address those specific issues related to ATMP. It includes for example the need of implementation of controls on logistical arrangements to administer product with short shelf-life, the need of specific arrangements for long-term follow up of the subjects, specific training on the mode af administration for some products. The document should be read in junction with the ICH Guideline on GCP applying as well to ATMP.

European Medicines Agency (EMA)

One year report on the clinical data publication (Policy 0070)

Since October 2016, the European Medicines Agency (EMA) proactively publishes clinical data submitted by pharmaceutical companies to support their marketing authorisation applications (MAA) for human medicines under the centralised procedure. The clinical data, published on EMA’s clinical data website, include:

  • the clinical overview, providing a critical analysis of the clinical data in the submission package, including the conclusions and implications of the clinical data;
  • the clinical summary;
  • the study reports on the individual clinical studies;
  • three appendices to the clinical study reports, namely the study protocol, the sample case report form used to record information on an individual patient, and documentation of the statistical methods used to analyse the data.

The EMA is the first regulatory authority worldwide to provide open access to clinical data submitted by companies in support of their MAA but other regulators, such as the US Food and Drug Administration (FDA), are also implementing similar transparency measures.

The report published this month covers one year from the launch of EMA’s clinical data website and lists the 50 medicines for which clinical data were published, including orphan, paediatric, biosimilar and generic medicines. The report includes notably the results of a user survey of which the majoritystrongly agree that this initiative:

  • increases public trust in EMA’s decision-making and,
  • allows the reassessment of clinical data.

EMA states that due the current relocation to Amsterdam may impact the publication of clinical data as of the second half of 2018 and in 2019 due to prioritisation of critical activities at the agency

Final guideline on the “Quality, non-clinical and clinical aspects of Gene Therapy (GT) medicinal products”

This guideline is a revision of the Note for Guidance on the “Quality, Preclinical and Clinical aspects of gene transfer medicinal products”, which was published in 2001. The revision process started in 2015 is now finalised. The guideline discusses the quality, safety and efficacy requirements for GT. Many of EMA’s modifications are minor changes compared to the initial draft, such as revisions to the wording and additions of references to other texts reflecting the nature of most of the feedback EMA received from the industry.

Draft revision of guideline on the “Quality, non-clinical and clinical aspects of medicines containing genetically modified cells”

EMA released for public consultation a draft revision of the guideline on “Quality, non-clinical and clinical aspects of medicines containing genetically modified cells” last published in 2012. The guideline has been updated to consider recent developments in the field of genetically modified cell therapies.

  • The quality section has been updated to take account of the evolution of science and regulatory experience with an emphasis on starting materials (also considering implications for genome editing reagents/tools), comparability and validation.
  • The non-clinical section has been supplemented with current thinking on the requirements to conduct non-clinical studies and a specific section (6.3) on the scientific principles and guidance for CAR-T cell and TCR products, induced pluripotent stem cell derived cell-based products and cell-based products derived from genome editing.
  • The clinical section has been updated considering the experience of recent scientific advices and MAAs. An annex on clinical aspects specific to CAR-T cells has been prepared and included.

The guideline is in public consultation until July 2019.

EMA identifies gaps in industry preparedness for Brexit

Back in January 2018, EMA launched a survey to gather information from pharmaceutical companies on their Brexit preparedness plans and to identify any particular concerns with regard to medicines supply that may impact. For marketing authorisation holders (MAH) of centrally authorised products (CAPs), Brexit may imply:

  • a transfer of the Marketing Authorization (MA) to a legal entity established in the European Economic Area (EEA), or
  • a change of the qualified person for pharmacovigilance (QPPV) or pharmacovigilance system master file (PSMF) to a location in the EEA including adaptations to their logistics, manufacturing sites, supply chains and contracts.

EMA received feedback from MAHs on over 90% of CAPs with an important step in their regulatory processes in the United Kingdom (UK). Overall, the survey results indicate that the MAHs of CAP are taking steps to make the necessary changes to their MA to prepare for Brexit. However, analysis of the survey responses shows that 88 products are at potential risk of supply. EMA is liaising directly with the marketing authorisation holders who either did not reply to the survey or have indicated in the survey that they do not plan to submit the changes required by 30 March 2019 and have manufacturing sites in the UK only, as this could potentially lead to supply disruptions.

International Pharmaceutical Regulators Programme (IPRP)

Reflection paper on Expectations for Biodistribution (BD) Assessments for Gene Therapy (GT) Products

This month, the IPRP working on regulatory convergence in the ATMP field released reflection paper laying out expectations for non-clinical biodistribution (BD) assessments for gene therapies (GT). BD assessments are conducted to determine the distribution, persistence and clearance of gene therapy vectors in the body, which are critical factors for understanding the effects and safety of a GT.

The general principles outlined in the document are applicable to many GT products, but do not apply to genetically modified cells. The document discussed several aspects of BD studies; considerations for First-in-Human (FIH) clinical trials, design, assay methods, circumstances that trigger additional BD studies.

Another refletion paper from the Cell Therapy WG is expected to be submitted to the management committee for approval in the coming months on “General principles to address the nature and duration of follow-up for subjects of clinical trials using cell therapy products
