The first version of the Union list of critical medicines was published on 12 December 2023 by the European Commission, the European Medicines Agency (EMA) and the Heads of medicines Agencies (HMA).
The initiative is part of the actions planned according to the Pharmaceutical Strategy and the Communication on addressing medicine shortages in the EU. A Q&As documentwas also published to illustrate the main features of the list, together with the methodology to identify critical medicinesto be included in the list (see the dedicated webpage of EMA’s website). The first version of the Union list of critical medicines is comprehensive of approx. 200 active substances, selected starting from a pool of more than 600 referred to in the national lists of critical medicines of Finland, France, Germany, Portugal, Spain, and Sweden. These six countries were chosen as their lists were based on criteria aligned with those agreed for the Union list. The process also comprised consultations of key stakeholders, including patients and healthcare professionals’ organisations and industry associations.
The list will be updated annually, and further references will be added in 2024. The final list will also include the separate assessment of the vulnerability of the supply chains to be run by the European Commission.
The Union list will not replace existing national lists of critical medicines, that will continue to support national policy decisions. EU member states may also use the Union list to create their own national lists, if not yet available.
“Ensuring an uninterrupted supply of critical medicines is essential for a strong European Health Union. With the publication of the first Union list of critical medicines today, we are delivering on our promise to accelerate work in this area and to take every possible measure to avert the risk of shortages for our citizens”, said Stella Kyriakides, Commissioner for Health and Food Safety.
A list to prevent shortages
The Union list of critical medicines represents a warning about the importance of avoiding shortages for specific medicines, as they would highly impact both patients and healthcare systems. No immediate effect is expected on shortages, but the risk might decrease in the longer term.
The Union list specifies human medicines (both innovators and generics, vaccines, and medicines for rare diseases) those continued supply is considered a priority in the EU. It will be used by the EU Commission, EMA and HMA for the definition of proactive measures to strengthen the supply chain and minimise the risk of supply disruptions (see more on EMA’s webpage on Availability of critical medicines).
The Union list of critical medicines will also serve as the basis for the Commission to run the analysis of vulnerabilities, followed by recommendation of suitable measures in consultation with the Critical Medicines Alliance (we wrote about this part 1 and part 2). The Commission may issue recommendations for companies to diversify suppliers or increase production within the EU. Incentives to invest may also be used to favour the resilience of European manufacturing. As for procurement, strong contractual obligations for delivery may apply.
Medicines included in the Union list will also be prioritised for actions by the European medicines regulatory network, in charge of monitoring their availability and implementing measures to minimise the risk of supply disruptions. To this instance, existing processes and structures will be used as defined in the mandate of EMA’s Medicine Shortages Single Point of Contact (SPOC) Working Party and EMA’s Executive Steering Group on Shortages and Safety of Medicinal Products (MSSG).
No additional obligations have been introduced by now for marketing authorisation holders and national competent authorities. This will be a topic of discussions during the final phase of negotiations on the proposed revision of the EU pharmaceutical legislation.
The methodology to select critical medicines
The therapeutic indication and the availability of alternative medicines are the two main criteria for the insertion of a certain medicinal product in the Union list of critical medicines. Additionally, it has to be classified as critical in at least one-third (33%) of EU/EEA (European Eco-nomic Area) member states.
National lists of critical medicines may differ from one another, reflecting differences of the internal evaluation criteria used to assess criticality. For example, some products are marketed just in some countries, or alternatives are available in some countries and not in others. Furthermore, the Union list is still incomplete, as some important medicines have not yet been assessed at the central level. The Union list does not include as well products mentioned in the WHO list of essential medicines. Orphan medicines are included in the Union list if they meet the above-mentioned assessment criteria.
The document on methodology further clarifies the governance of the process and the matrix for identifying medicines to be included in the Union list of critical medicines. The methodology was created starting in 2021 (European Commission Structured Dialogue initiative), finalised by the HMA/EMA Task Force on the availability of authorised medicines for human and veterinary use (HMA/EMA TF-AAM), and finally adopted in June 2023.
The medicinal product criticality is evaluated on the basis of a risk assessment. As for therapeutic indications (criterion 1), all authorised medicines in a member state should be classified, irrespective of their marketing status. Criterion 2 refers to the availability of alternatives, and only authorised medicines marketed in the respective member state should be classified.
A low, medium or high-risk level is assigned for each of the two above-mentioned criteria, thus resulting in a risk matrix. The exercise allows to assign the medicine in one of the following categories: critical medicines, medicines at risk, other medicines.
Medicines considered at high risk with respect to their therapeutic indication refers to products those use may have very serious implications for the health of individual patients or public health (general life-threatening acute conditions, specific life-threatening acute conditions, or irreversibly progressive conditions). Evaluation parameters include the fact the disease is potentially fatal, irreversibly progressive or, if left untreated, will pose an immediate threat to the patients. Furthermore, the treatment must be administered immediately or within regular dosing intervals, and the product has to be part of a national disease control program.
Appropriate alternatives are identified according to the fact they are authorised for the same therapeutic indication and are available on the market in the respective member state. Furthermore, alternative treatment has to be clinically possible, without negative impact on the patient’s health and providing the same quality of care standard. As for criterion 2, high risk cri-tical medicines refer to products for which no appropriate alternative is available, or only one appropriate alternative (product) on ATC level 4 or 5 (same active substance or alternative is within the same ATC level 4 group or in another ATC level 4 group) is available.
Public consultation for the review of HERA
We inform all interested EIPG’s members that the public consultation for the review of the Health Emergency Preparedness and Response Authority (HERA) is open until 19 February 2024 and it can be accessed through the dedicated webpage of the EU Commission website.
The consultations aim to assess how HERA’s mandate and tools contributed to achieve EU’s political objectives, and how the Authority complements the work of other EU bodies and responds to the current health challenges.
Reactions to the proposed ban of PFAS
by Giuliana Miglierini
A proposal to ban around 10,000 per- and polyfluoroalkyl substances (PFAS) was submitted in January 2023 to the European Chemicals Agency (ECHA) by authorities of Germany, Denmark, the Netherlands, Norway, and Sweden. The proposal was published on ECHA website on 7 February 2023.
The focus is the so-called “forever chemicals”, i.e. very high persistence PFAS typically characterised by bioaccumulation (also in plants), great mobility and a long range transport potential, and potential endocrine activity.
“This landmark proposal by the five authorities supports the ambitions of the EU’s Chemicals Strategy and the Zero Pollution action plan. While the evaluation of such a broad proposal with thousands of substances, and many uses, will be challenging, we are ready.”, said Peter van der Zandt, ECHA’s Director for Risk Assessment.
The proposal was open to public consultation on 22 March 2023, giving rise to the collection of 5,600 comments. Opinions will be issued by ECHA’s scientific committees for Risk Assessment (RAC) and for Socio-Economic Analysis (SEAC), to be then forwarded to the EU Commission for final decision.
The current role of PFAS
PFAS are characterised by the presence of alkyl groups in which many or all the hydrogen atoms have been replaced with fluorine. The main carbon chain of these substances may have different lengths, from small molecules to long chain PFAS and polymers, and may carry a very wide variety of other functional groups. The strength of the carbon-fluorine bond is the root cause of PFAS persistence, leading to these substances remaining in the environment for decades to centuries.
Per- and polyfluoroalkyl substances are currently used in many different industrial sectors, thanks to their useful technical properties. Among others, PFAS can be used to repel water, oil and dirt from surfaces, and is characterised by a high durability under extreme conditions of temperature, pressure, radiation, and chemicals. PFAS also present electrical and thermal insulation properties.
The main features of the restriction proposal
According to the authorities that submitted the proposal, around 4.4 million tons of PFAS would end up in the environment over the next 30 years in the case of no action. Ban would refer to manufacture, placing on the market and use as such, as constituent in other substances or in mixture as well as in articles.
Two options for restriction have been considered, a full ban or specific derogations for certain industries, based on the analyses of alternatives, efforts put in place for switching to them, and socio-economic considerations. The ban would be effective above a set concentration limit; a transition period of 18 months should occur between final adoption and entry into force. Use-specific, time-limited derogation might refer, for example, to a 5-year period in the case of food contact materials for industrial food and feed production (as alternatives are already under development, but are not yet available to entry into force), or to a 12 years for implantable medical devices (for which identification, development and certification of alternatives is still needed).
During the public consultation phase, comments were received from more than 4,400 organisations, companies and individuals, to be reviewed by both the RAC and SEAC committees and the five proposing countries. Sweden, Germany and Japan are the countries that contributed the higher number of comments, well in advance of Belgium, China, Italy and the US. Companies provided more than the half of the comments (58,7%), followed by individuals (27,3%), and industrial or trade associations (9,8%). The full list of entities participating to the consultation is available at the consultation webpage.
EFPIA response to ECHA’s consultation
The European Federation of Pharmaceutical Industries and Associations (EFPIA) contributed to the consultation with a detailed document. Another joint ISPE-EFPIA document particularly addressed the use of fluoropolymers and fluoroelastomers in medicinal product manufacturing facilities.
“While we support the need to restrict certain PFAS, we need to find the right approach to ensure the continued manufacturing and availability of medicines in Europe. A total ban would see medicines’ manufacturing in the EU grind to a halt in under three years. It would also jeopardise the production of all pharmaceutical substances in Europe and would conflict with the EU’s strategy of reducing dependency on nations outside of the EEA in the event of shortages or pandemics.”, said EFPIA’s director general, Nathalie Moll.
EFPIA’s consultation documents highlights the many different uses of PFAS in the pharmaceutical industry, ranging from active pharmaceutical ingredients (API) falling within the definition of PFAS used in the proposal, to building blocks and raw materials used within chemical synthesis of PFAS and non-PFAS medicines. Other reagents and equipment might also fall within the scope of the ban, as well as packaging materials or combination products such as pre-filled syringes. The ban would also affect the manufacturing process, where PFAS materials are used in a wide variety of applications.
It might thus result in the disappearance from the market of a large number of important medicines, warns EFPIA, due to the unavailability of replacement materials, and the time required to obtain regulatory re-approval of alternatives. The supply chain of pharmaceuticals would be also impacted at many stages, thus possibly exacerbating shortages.
In its analysis, EFPIA highlights how some PFAS are considered of low concern by the OECD, and in particular “those used in actual medicines have no or low identified risk through medicines risk benefit or environmental risk assessments”.
A patient access impact analysis was also jointly developed by the involved industrial associations (AESGP, EFCG, EFPIA, Medicines for Europe and Vaccines Europe), showing that the current proposal would lead to at least 47,677 global marketing authorisations being affected by the ban. More than 600 medicines from the WHO Essential Medicines List would be at risk; restrictions would greatly impact also the European Member State’s “Critical Medicines lists”.
EFPIA submitted also a socio-economic assessment of the proposal, according to which a broad restriction of PFAS used in the production of human medicines would have disproportionate negative impacts on the European economy and society. “Without additional derogations, the entire pharmaceutical industry would no longer be able to manufacture active pharmaceutical ingredients (APIs) (whether classified as PFAS or non-PFAS APIs) or associated medicinal products in the EEA”, writes EFPIA, resulting in APIs production to necessarily move out of the European Economic Area.
The position of the medical device sector
MedTech Europe also published a position paper on the PFAS restriction proposal and called for “a realistic transition pathway to non-PFAS alternatives that are both reliable and feasible for medical technologies (including their manufacturing and supply chain) to avoid shortages of medical technologies for patients and practitioners”.
The position paper presents many PFAS use cases in the field of medical devices, together with the criticalities posed by the proposed transition. In particular, broad derogations should be considered to allow sufficient time to first “identify all PFAS uses in medical technologies and to subsequently move to alternatives where these are proven to be technically viable, available besides in conformity with the sector-specific MD and IVD Regulations so as fit for the intended purpose”. In this case too, the need to manage complex supply chains would require a realistic timeline in order to address dependencies, and long development timelines and steps to ensure compliance with the sectorial legislation.
