The European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) each offer applicants for marketing authorization of a drug or investigational medicinal product the opportunity to seek scientific advice on specific issues related to the development of a drug product. For pharmaceutical companies seeking approval in both the EU and the U.S., consultation with one or the other agency can often result in additional work due to duplicate testing and divergent testing methods because of differing standards and guidelines in the respective approval process. The possibility of a Parallel Scientific Advice (PSA) procedure, in which both regulatory authorities are involved at the same time, provides a remedy for this and has already existed for several years. The basic principles for this procedure have now been renegotiated between the EMA and the FDA and published in the document "General Principles EMA-FDA Parallel Scientific Advice (Human Medicinal Products)" on the websites of both authorities in July 2021.
The core contents of the updated Parallel Scientific Advice procedure are summarized below.
Sponsors or applicants seeking approval for an investigational new drug (IND) in the U.S. or a new drug or biologic drug (New Drug Application, NDA, or Biologic License Application, BLA) and simultaneously seeking marketing authorisation in the EU are eligible for this process.
Medicinal products for which the procedure will bring the greatest benefit are, for example, oncological preparations, anti-infectives, medicinal products for rare diseases, pediatric medicinal products, medicinal products for the therapy of cardiovascular diseases, and medicinal products with indications for the development of which no or divergent guidelines exist.
The result of the consultation, the written recommendation, is then only sent by the authority where the consultative procedure was initiated.
Requests for a PSA should be sent to both authorities at the email addresses provided in the "General Principles..." document. The request should include the following information:
No later than 70 days after approval of the PSA, the sponsor/applicant receives a confirmation letter via email from each authority, indicating the contact person who coordinates the procedure. In the PSA Joint Meeting (tele- or videoconference), representatives of both authorities and the sponsor/applicant participate to discuss the issues and seek clarification. If necessary, a pre-sponsor meeting can be held before or a post-sponsor meeting after the joint meeting, in which only the representatives of the two authorities participate.
The individual phases with the respective time windows and the total duration of the procedure are clearly presented on two charts on the EMA website.
A detailed description of all aspects of the EMA's advisory procedure can be found on its website under the heading "Scientific advice and protocol assistance".
