PURPOSE OF THE NEW REGULATION. On June 13, 2024, the European Parliament and the Council adopted a new regulation on the substances of human origin (so-called SoHO), repealing Directives 2002/98/EC and 2004/23/EC. The new regulation:

• was necessary because previous directives only partially managed to harmonize member states’ legislation on cells, tissues and blood; also, a new definition of SoHO was needed;
• introduces mechanisms to grant continuity and resilience of SoHO supplies and to facilitate EU cross border exchanges and access to SoHO;
• enhances safety of donors and recipients (included the offspring born from medical assisted procreation).

WHAT IS A ‘SOHO’? A SoHO is now defined as “any substance collected from the human body, whether or not it contains cells and whether or not those cells are alive, including SoHO preparations resulting from the processing of the above-mentioned substance”. The definition has been expanded to include breast milk and gut microbiota, as well as blood preparations different from those used for transfusions. Any future SoHO will be automatically included in the regulation. The regulation also defines SoHO preparation as a SoHO subjected to processing, with a specific clinical indication, intended for human application on a recipient or for distribution.

WHO DEALS WITH SOHO? The regulation also defines which will be the main actors in the organizational chain from SoHO donation to application. Specifically:

• A SoHO entity is a legal entity established in the EU that carries out SoHO-related activities (e.g. collection, processing, control, storage, release, distribution, import, export, application on human beings,  clinical studies and outcomes recording on SoHO preparations)
• A SoHO establishment is a SoHo entity that carries out one of the following SoHO-related activities: A) both processing and storage; B) release; C) import; D) export;
• Competent authorities for SoHO are appointed by each member state and 1) maintain SoHO entities’ registry, 2) deal with authorization process for SoHO establishments and SoHO preparations 3) carry out inspections and evaluate plans for monitoring clinical outcomes.

WHEN?  The regulation will be enforceable by mid-2027.

TAKEAWAYS. Apparently, it is science-friendly as the definition of SoHO will be broader and more flexible than before. Also, in view of its structure, there is hope that it will succeed in ensuring more uniformity and granting an enhanced minimum level of safety across EU.
