The long-waited European regulation on Health Technology Assessment (HTA) was adopted by the Council of Europe on November 9, and it has now to pass through the final endorsement of the European Parliament as the last step before publication in the EU Official Journal. The regulation will entry into force three years and twenty days after publication.
The first proposal of a new HTA regulation was made in January 2018 by the EU Commission; the final political agreement between the Council and the EU Parliament was reached in June 2021. The position of the Council of Europe on the draft regulation at first reading was also published.
The provisions of the new HTA regulation will apply to medicinal products, medical devices (for example pacemakers, dialysis equipment or infusion pumps) or medical and surgical procedures, as well as measures for disease prevention, diagnosis or treatment used in healthcare.
“The adoption of this law is another demonstration of how EU countries, when acting together, can achieve very practical results for their citizens. This new law will benefit patients, producers of health technologies and our health systems.”, said Janez Poklukar, the Slovenian minister for health.
Cooperation and joint activities
Joint clinical assessments and joint scientific consultations are central concepts of the HTA regulation: a target that would require the active cooperation of all member states in order to efficiently identify emerging health technologies. Administrative procedures shall be greatly simplified and become more cost-efficient, as manufacturers of health technologies (especially small companies) should be required to submit once-only all data and documentation for a certain technology at the EU level. These will form the basis for national competent authorities to run all joint activities, including scientific advice and clinical assessment.
The added value of new health technologies compared to the existing ones will be a main driver to guide the assessment activities, so to take informed decisions on pricing or reimbursement.
Joint scientific consultations may also include the exchange of relevant information between national authorities and manufacturers on development plans for the technology under assessment, so to favour the availability of all the evidence required to meet regulatory expectations.
The new Heads of Agencies Group
While waiting for the formal adoption of the new HTA regulation by the EU Parliament, other activities are ongoing to set up the operative framework needed to guarantee the smooth activation of all planned collaborative efforts.
The newly formed Heads of Agencies Group (HAG) is an initiative aimed to support the implementation of common joint work approach on all HTA activities at the EU level, according to the new model of cooperation among national authorities established by the regulation.
The new HTA-focused collaborative network for high-level strategic exchange and discussion was launched on 29 September 2021 by the heads of 19 European HTA agencies, which elected Prof. Rui Santos Ivo (INFARMED, Portugal) as its Chair, and Prof. Dominique Le Guludec (HAS, France) and Dr. Trygve Ottersen (NIPH, Norway) as Vice-Chairs. The secretariat of the Group has been established at the Dutch Health Care Institute (ZIN).
All HAG’s activities will be based on a joint Memorandum of Understanding. The Group will work during the next three years to support national systems to be prepared for the entry into force of the HTA regulation, including the availability of the needed capacity. HAG will also support the joint technical and scientific work performed by HTA bodies across Europe, and it will advise policymakers and other relevant institutions – both at the EU and national level – on issues related to cooperation in HTA.
Current members of the group include the following national authorities involved in HTA activities: AEMPS (Spain), AIFA (Italy), AGENAS (Italy), AIHTA (Austria), INFARMED (Portugal), KCE (Belgium), NIPH (Norway), G-BA (Germany), HAS (France), HIQA (Ireland), IQWiG (Germany), FIMEA (Finland), NCPE (Ireland), REDETS (Spain), RER (Italy), RIZIV-INAMI (Belgium), NOMA (Norway), TLV (Sweden) and ZIN (The Netherlands).
The EUnetHTA 21 consortium
After the closing of its third Joint Action (2016-2020), which paved the way to the permanent HTA working structure for Europe (encompassing more than 80 HTA bodies), the European Network for Health Technology Assessment (EUnetHTA) has published a HTA White Paper as the final document resuming lessons learned up to now that may prove relevant for the implementation of the next phase of the HTA joint cooperation.
This new phase in the life of the Network, that now goes under the name of EUnetHTA 21, is no more a Joint Action; a joint consortium has been created instead, led by the Dutch HTA body ZIN and including the following HTA agencies: AEMPS (Spain), AIFA (Italy), AIHTA (Austria), GBA (Germany), HAS (France), INFARMED (Portugal), IQWIG (Germany), KCE (Belgium), NCPE (Ireland), NIPN (Hungary), NOMA (Norway) and TLV (Sweden). The consortium will provide support to the future European HTA system to be established according to the upcoming regulation.
EUnetHTA 21 is funded by a two-years’ Service Contract for the Provision of Joint Health Technology Assessment (HTA) Work Supporting the Continuation of EU Cooperation on HTA, signed on 17 September 2021 by the European Health and Digital Executive Agency (HaDEA).
The first Stakeholder Kick-Off online meeting of the consortium is scheduled on 3 December
2021; the discussion will focus on the illustration of the governance principles, the planned interactions with stakeholders in the form of public consultations and the presentation of deliverables planned for the next two years.
The first Open Call for consultation
EUnetHTA 21 has already launched its first Open Call , targeted to the pharmaceutical industry with reference to four different Joint Scientific Consultations (JSC, previously referred to as Early Dialogues). The Call is open until 7 December 2021; some other four slots for JSC are expected to be activated during the period of activities of EUnetHTA 21.
The medicinal products to access these four first slots will be selected on the basis of the results of the Open Call, within two weeks from its closure; the following Joint Scientific Consultations are expected to start in January 2022. According to EUnetHTA, the procedure to be used for JSC shall remain essentially unchanged, with just minor adjustments; an updated guidance document should be soon available.
JSCs are a pillar of the new HTA regulation, aimed to provide non-binding scientific advice to developers of new products, after completion of the feasibility or proof of concept studies and prior to the activation of pivotal clinical trials, in order to improve the quality and appropriateness of the data to be used for future HTA assessment. This type of evaluation will run in parallel to EMA’s scientific advice procedures.
Early exchange of relevant information between applicants and both regulatory (EMA) and HTA agencies represents the core of the process, so to optimise the integration of the different requirements to be included in the study design across multiple European member states. These might refer, for example, to the choice of comparators or relevant outcomes, to the quality of life and/or patient groups (both for pivotal trials and post-launch studies), as well as to the economic evidence generation plan.
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.
