EMA CAT Protocol Assistance Strategy in 2023: Orphan/ATMP Synergies and Fee Reductions

In the ever-evolving landscape of Advanced Therapy Medicinal Products (ATMPs), understanding the regulatory framework established by the European Medicines Agency (EMA) is paramount for pharmaceutical companies and clinical research professionals. This comprehensive guide delineates the detailed steps for utilizing the EMA’s Committee for Advanced Therapies (CAT) Protocol Assistance strategy, outlining synergies with orphan drug designations and potential fee reductions available under current regulations.

This article provides an extensive exploration of the EMA ATMP regulatory consulting process, designed specifically for stakeholders in the United States seeking to navigate the complexities of European regulations.

Step 1: Understanding the Scope of EMA CAT Protocol Assistance

The first step in engaging with the EMA’s CAT Protocol Assistance is to clearly understand its scope and objectives. The EMA’s CAT is specialized in the evaluation of ATMPs, which include gene therapies, somatic cell therapies, and tissue-engineered products. The Protocol Assistance provides guidance to developers addressing the quality, safety, and efficacy of ATMPs before

their formal submission for marketing authorization.

To comfortably maneuver within this framework, you should familiarize yourself with the specifics detailed in the EMA CAT guidelines and the regulations set forth in the EU legislation. This includes an understanding of the pivotal definitions, such as what constitutes an ATMP, and the criteria for eligibility regarding the protocols for assistance.

During this stage, it is crucial to determine whether your product qualifies as an orphan medicinal product as defined by Regulation (EC) No 141/2000. This classification not only aids in establishing your regulatory strategy but may also provide valuable synergies, such as fee reductions for applicants, which will be explored further in this article.

As a preparatory action, gather all relevant scientific data, preclinical study results, and preliminary clinical data that can substantiate your product’s potential innovation. This documentation will provide a foundation for the subsequent steps in the consultation process.

Step 2: Eligibility Assessment and Consultation Request Preparation

The second step involves assessing the eligibility of your product for the EMA CAT Protocol Assistance. EMA regulations stipulate that you can request protocol assistance before submitting a marketing authorization application, and understanding the prerequisites is essential for a successful application.

Begin by compiling essential documents including, your product’s information, target patient population, intended indications, and any previous regulatory submissions. This preliminary documentation will facilitate a clear presentation of your case to the EMA.

The submission must include a detailed description of the ATMP’s development program, including the manufacturing process detailed in the [Annex 2](https://www.ema.europa.eu/en/documents/scientific-guideline/manufacture-advanced-therapy-medicinal-products-annex-2_en.pdf) guidelines, which outlines the requisite quality requirements for ATMPs. Also, prepare an indication of the type of assistance you seek: whether it is scientific, regulatory, or fee-related.

Once you have compiled your documents, ensure to engage with your internal regulatory affairs team to refine the text, ensuring that it meets EMA’s structured requirements and is scientifically robust. The aim is to convey the scientific rationale and justification for your proposed development pathway clearly. Set internal deadlines well ahead of the planned submission date to allow time for review and revisions.

Step 3: Submission of the Protocol Assistance Request

Following the completion of documentation, the next stage is the formal submission of your request for protocol assistance. The EMA accepts submissions electronically, and it is crucial to utilize the Common European Submission Portal (CESP) for your submission. Ensure that your request complies with the specific requirements set forth by the EMA to avoid delays in processing.

When submitting your request, include the following key components:

  • Cover letter outlining your request for assistance.
  • Summary of product information.
  • Details of the developmental program, including planned studies.
  • Specific questions or areas where feedback is sought from the EMA.
  • Proposed timelines for your study programs.

Upon submission, you will receive confirmation from the EMA regarding the receipt of your request. This step marks the transition to the EMA’s review phase. It is advisable to be proactive by scheduling a follow-up meeting around the expected review date to discuss preliminary feedback, if possible, ensuring alignment with the regulatory expectations.

Step 4: EMA Review Process and Feedback Loops

The EMA’s review process typically spans several months, during which the Committee for Advanced Therapies reviews your submitted protocol assistance request. The EMA will assess the scientific and regulatory rigor of your plan, ensuring it aligns with EU guidelines. Be prepared for the possibility of receiving requests for additional information or clarification.

The review body may provide advice and feedback regarding various regulatory strategies, including the potential benefit of pursuing a centralized procedure for your ATMP, which can streamline the marketing authorization across EU member states. Key aspects to consider during the review include:

  • Quality requirements and compliance with GMP regulations.
  • Safety and efficacy assessments based on proposed studies.
  • Long-term follow-up plans for safety evaluations post-approval.

It is critical to maintain an open line of communication with the EMA team during this period. The feedback you receive can significantly influence the finalization of your clinical trial design, paving the way for a more robust marketing authorization application. Also, ensure that your responses to their feedback are comprehensive, directly addressing their concerns with supporting scientific evidence.
