About Biopharmaceuticals
Biopharmaceuticals are produced in living cells or extracted from human plasma, unlike synthetic drugs which are the result of chemical processes.
Since its introduction in 1982, biopharmaceutical drugs have revolutionized the treatment of a broad spectrum of diseases and are increasingly used in nearly all branches of medicine.
In recent years, the biopharmaceuticals market has developed much faster than the market for all drugs They are crucial for treating various pathologies such as cancer, and patients rely on their availability.
Advantages over synthetic drugs
they target only specific molecules, rarely causing the side effects associated with
conventional small-molecule drugs.
Thus, they are vital for patients in volatile conditions.
Biopharmaceuticals are vital for medicine and have advantages over synthetic drugs, including targeting specific molecules and
causing fewer side effects.
They exhibit high specificity and activity.
some patients react poorly to synthetic drugs, thus they are dependent on the broad availability of biopharmaceuticals

biopharmaceutical drugs, ensuring that biopharmaceuticals are safe,
ultimately protecting human health and patient safety.
Required step by various Directives and Guidelines
Nanofiltration & Microfiltration
Nanofiltration
a well-established method allowing the removal of viruses
based on size-exclusion that entails filtering of protein solutions through membranes with pores of nanometric sizes that have the capability to effectively retain a wide range of viruses.
The use of this filter during nanofiltration is a necessary step in the production of biopharmaceuticals to effectively remove viruses from the end-products, i.e. human medicines.
Microfiltration
designed to have a higher filterability of antibodies.
a well-established method that allows the separation of the antibodies (proteins) from the animal cells.
The use of this filter during microfiltration occurs upstream in the filtration of impurities, before the virus removal stage.
Necessary step in the production of biopharmaceuticals aimed to separate the animal cells from the antibodies.
Why nanofiltration in the first place?
1. Inherent risks
Biological products, made from human or mammalian cells possess an inherent risk of being contaminated by viruses that can be pathogenic to humans.
2. Societal Implications in case of a viral contamination
significant burden from financial, regulatory and time aspects
implies that production at the facility where it occurred is stopped until the causes are eliminated.
may lead to product shortages for patient treatments
3. Product Requirement
In addition, the safety and efficacy of biopharmaceuticals in humans require drugs of highest purity, right concentration allowing the API to work effectively

In recent years nanofiltration has increasingly become dominant in the field of human plasma derived products. 1997 two out of seven products licensed contained a nanofiltration step, this rate increased to 6 out of 7 in 2000 and 100% in 2002 and 2003
Note for microfiltration: These filters are in the market entry/market development stage and are being trialled by some EU drug manufacturers as they can increase productivity significantly.

REACH PFAS Annex XV - Our Concerns
THE PROPOSAL BY 5 COUNTRIES IS FLAWED
No derogations, only bans (+18 months after EiF) or "delayed bans" (+6.5 or +13.5 years after EiF)
Persistency - main criterion for ban ("P-sufficient approach"): No hazard assessment No information on use resulting in emissions Nor risk assessment Insufficient analysis of alternatives No causal link between alleged presence of PFAS and actual fluoropolymers usage
Wrong premises (e.g. non-fluorinated polymerization aids are `better' for the environment)
Alternative RMOs not considered
OVERALL: no demonstration of unacceptable risk & no recognition that fluoropolymers can be produced responsibly
DIRECT IMPACT ON PVDF 1. All PFAS as per definition, unless explicitly derogated, will be
banned as from July 2027 2. Most substances will be completely banned after a transition
period (if at all) 3. While the report includes consideration of the use of PFAS in
medical device and some limited pharmaceutical applications, the biopharma sector is a missing use category and needs to be appropriately considered 4. PVDF in medical biotherapeutic filters are in scope of restriction proposal. 5. Fluorinated Polymerization aids are banned for the production of PVDF 6. Transported isolated intermediates used under strictly controlled conditions are banned (contrary to REACH). OVERALL: indirect ban on high-tech economic sectors, including green technologies, relying on fluoropolymers.

Use operated by trained professionals, with no
exposure to workers or patients as the PVDF membrane is encapsulated in the filter. No adverse events related to nanofiltration have been recorded so far, and regulators recognize and mandate it as a safe virus removal method.
End of life Filter are considered as hazardous waste
under the Waste Framework Directive. filters need to be incinerated due to their
contamination with pathogens at special facilities as hazardous waste at high temperatures Under these extreme conditions, the C-F bond breaks down, thus completely destroying any PFAS (confirmed by several studies) next slide
NO Risks
Fluoropolymers, such as PVDF, do not pose any risks to the environment and human health
and should be generally exempted
from the PFAS Restriction
End of Life - Mandated Incineration
Under EU and national legislations, filters need to be incinerated due to their contamination with pathogens at special facilities as hazardous waste at high temperatures.
For hazardous waste, the minimum temperature of the combustion gases must be 1100 C Polytetrafluoroethylene (PTFE or Teflon) is the most stable fluorine containing polymer and it can
be concluded that complete thermal decomposition is achieved at a temperature of about 800 C. Other fluorine-containing polymers thermally decompose completely at a temperature of 850 C.

depending on the functional groups in the PFAS, sulphur dioxide, phosphorus oxide and nitrogen dioxide Additional cleaning steps for the flue gas are required/mandated to remove potential remaining pollutants

The European biopharmaceuticals market was estimated to be worth $48.2 (44.6) billion in 2022 and it was disclosed to RPA that up to 10% of the
Turnover
European biopharmaceuticals market uses F8 for virus removal. Based on these estimations, it can be assumed that these drug manufacturers
have a revenue of $4.82 (4.46) billion associated with the use of F6 . This could be at risk under the NUS.
Profit
It is also expected that this level of business lost could also negatively impact the profitability of these downstream users and therefore may also come with other impacts arising from the loss of business.

Based on a report by the European Commission in 2019, there were 2.4 million employees in Europe's biopharmaceuticals industry. Assuming 10% of
Employment the biopharmaceuticals market in Europe uses F6 , it can be assumed that 240,000 employees in Europe have jobs associated with the use
of F6 . These jobs could be at risk under a NUS.

Alternatives
F9
There are three primary types of nanofiltration, each designed for their unique use case and environment, as such they cannot be interchanged 1:1.
EMA guidance recommends the use of orthogonal technologies for virus removal; to use at least two independent virus removal technologies that use different modes of action. Any switch to an alternative type of virus removal must retain this orthogonality requirement.
PVDF enables nanofiltration, which is the only process in the nanofiltration targeting effectively smaller viruses.
There are practically no alternatives that can replace the high performance provided by PVDF in in the biopharmaceutical sector and Protein concentration plays a crucial role in determining the right filter. (See Image) - However, taking significant trade-offs into account a switch to alternatives may be possible in the long term (Note: Alternatives may use PVDF in their housing) E.g. Both types of filters are widely used in pharmaceutical products which are in clinical trials. Data from such manufacturing trials are used in the
dossier to apply for a Marketing Authorisation for the drug (i.e., a drug licence). For customers engaged in this process, a need to switch to alternative filtration technologies will mean the data collected up to that point would no longer be able to be used for the Marketing Authorization application, and the trial process would need to be re-started, taking additional time and cost. alternatives have a lower transmission of the targeted protein of interest while only PVDF can meet the various performances required for drug product applications PES and polysulfone require an asymmetric pore structure, causing the clogging of the membrane interior progresses during filtration 10-15 years of development and regulatory timeframe required for the development of alternative filters and the availability of certain biopharmaceuticals may be negatively affected

8 Legal Areas of Concern
1. There are inaccuracies in the conditions on the proposed restriction - no exemption or derogations for the biopharmaceutical sector and V1 Medical products;
2. PVDF is generally included among more than 10,000 substances that possess different properties;
3. PVDF would fall under the scope of the restriction by solely meeting a non-legally binding accepted definition;
4. The assessment of hazard and risks of PVDF does not
appear legally sound;
5. The grouping approach is incorrect;
6. There is insufficient information on the uses, resulting emissions or exposure of PFAS in the biopharmaceutical manufacture sector;
7. The information on alternatives is not properly assessed as regards the production of PVDF;
8. The Proposal does not properly assess the interplay with other EU legislation such as the EU Pharmaceutical legislation.
As such, the proposal opposes the principles of 'Better Regulation' and creates significant uncertainties on the market

Way Forward
Preferred RMO
The restriction of PFASs must be substance-related and risk-based (Article 68 para. 1 of the REACH Regulation).
It is clear that not all PFAS pose an unacceptable risk that would justify a restriction. Especially, the restriction must differentiate between the different groups of PFAS and the risks, and the risks posed by their uses.
Fluoropolymers, such as PVDF, do not pose any risks to the environment and human health and should be generally exempted from the PFAS Restriction or benefit from a time-unlimited derogation.
Alternative RMOs
Option 1: V1 Medical products (biotherapeutic filters) should
be exempted a priori from the Proposal as they should not be covered by the REACH Regulation; or,
Option 2: V1 Medical products should be exempted a priori
from the Proposal as they are used in a closed system; in alternative,
Option 3: V1 Medical products should benefit from a time-
unlimited derogation in relation to the Proposal as the same rationale of plant protections products, biocides and human and veterinary medicines should apply.
