Generating pathways to domestically sourced plasma-derived medicinal products: Report from a workshop by the International Plasma and Fractionation Association and the Working Party on Global Blood Safety of the International Society of Blood Transfusion.

Plasma-derived medicinal products (PDMPs) are recognized internationally as essential medicines required to treat various acute and chronic conditions including congenital deficiencies of plasma proteins in haemophilia and primary immune deficiency. Global provision of these medicines is dominated by a small number of commercial companies, influencing the price and availability of the products. Achieving a level of strategic independence from this dominance is now seen as a public health priority in many countries. During the Regional Congress of the International Society for Blood Transfusion (ISBT) in Cape Town, South Africa, in November 2023, around 50 delegates from 24 countries participated in a workshop (WS) organized jointly by the International Plasma and Fractionation Association (IPFA) and the ISBT Working Party on Global Blood Safety on pathways towards provision of PDMPs from domestic plasma independent of commercial purchase in the open market. The WS was structured around three themes, each addressed by a separate group: Quality/safety requirements for plasma for fractionation (PfF) Stepwise access for safe plasma proteins Approaching contract fractionation A synthesis of conclusions from these groups included the following: The need to acquire support from government authorities for a national plasma policy, recognizing the difficulties posed by unstable political and bureaucratic environments. The value of embedding plasma and PDMPs within a patient blood management (PBM) paradigm to promote optimal clinical use of PDMPs. Training of blood/plasma collection personnel in the relevant principles of Good Manufacturing Practice (GMP), coupled with regulatory oversight of plasma product production in the engaged jurisdictions. Appreciation that limited access to contract fractionation may necessitate a stepwise approach, which may include small-scale preparation of versions of essential plasma proteins as an intermediate phase towards the manufacture of industrial-scale PDMPs from domestic plasma.

Safety profile of plasma for fractionation donated in the United Kingdom, with respect to variant Creutzfeldt-Jakob disease.

Plasma-derived medicinal products (PDMPs) are life-saving and life-improving therapies, but the raw material is in short supply: Europe depends on importation from countries including the United States. Plasma from donors resident in the United Kingdom has not been fractionated since 1999 when a precautionary measure was introduced in response to the outbreak of variant Creutzfeldt-Jakob disease (vCJD). Cases of vCJD have been far fewer than originally predicted in the 1990s. Since the introduction of leucodepletion in 1999, and accounting for the incubation period, more than 40 million UK-derived blood components have been issued with no reports of TT vCJD. In February 2021, the UK Government authorized manufacture of immunoglobulin from UK plasma. Following separate reviews concluding no significant difference in the risk posed, the United States, Australia, Ireland and Hong Kong also lifted their deferrals of blood donors with a history of living in the United Kingdom. Other countries are actively reviewing their position. Demand is rising for PDMPs, and Europe faces a threat of supply shortages. Industry and patient groups are clear that using UK plasma would bring significant immediate benefits to patients and to the resilience of the European supply chain. From this scientific review, we conclude that UK plasma is safe for fractionation and urge blood regulators and operators to take account of this safety profile when considering fractionation of UK plasma, and to revise their guidelines on the deferral of donors who have lived in, or received a transfusion in, the United Kingdom.

Plasma collection and supply in Europe: Proceedings of an International Plasma and Fractionation Association and European Blood Alliance symposium.

At the symposium organized by the International Plasma and Fractionation Association and European Blood Alliance, experts presented their views and experiences showing that the public sector and its blood establishments may strengthen the collection and increase the supply of plasma using the right strategies in plasma donor recruitment, retention and protection, scaling-up collection by increasing the number of donors within improved/new infrastructure, supportive funding, policies and legislation as well as harmonization of clinical guidelines and the collaboration of all stakeholders. Such approaches should contribute to increased plasma collection in Europe to meet patients' needs for plasma-derived medicinal products, notably immunoglobulins and avoid shortages. Overall, presentations and discussions confirmed that European non-profit transfusion institutions are committed to increasing the collection of plasma for fractionation from unpaid donors through dedicated programmes as well as novel strategies and research.
