The ‘Achilles’ project: a WHO initiative to support quality in the manufacturing of plasma for fractionation Dr Ana Padilla, Blood Products & related Biologicals Essential Medicines and Pharmaceutical Policies Department Health Services and Systems Cluster World Health Organization WHO Norms and Standards: Blood Products & related Biologicals WHO Expert Committee on Biological Standardization WHO Blood Regulators Network OUTLINE WHO Essential Medicines List Plasma for Fractionation The "Achilles" Project: Rationale and scope Project goals WHO action plan Expected outcomes 3 | HSS/EMP/BPB: Teheran, Oct 08 Blood Plasma: a valuable human resource Medicinal products derived from human donations of blood and plasma play a critical role in health care 4 | HSS/EMP/BPB: Teheran, Oct 08 Human Plasma Human Blood Plasma Complex mixture of (glyco)proteins Therapeutic product (plasma for transfusion = fresh frozen plasma) Pooled plasma = starting material for fractionation to medicinal products: Albumin Blood Coagulation Factors (e.g. F VIII, FIX) Immunoglobulins (IV, IM) Serine proteases Fibrin sealants 5 | HSS/EMP/BPB: Teheran, Oct 08 WHO Essential Medicines List Human derived blood plasma products – Plasma for Fractionation • • • • Blood Coagulation Factors: FVIII, PCC Human Normal Immunoglobulin (IV and IM) Anti-D immunoglobulin Anti-tetanus immunoglobulin Blood-derived medicinal products for the treatment of haemophilia and immune diseases are included in the WHO Model List of Essential Medicines 6 | HSS/EMP/BPB: Teheran, Oct 08 What is of the global situation ? Availability blood plasma products The global need for blood plasma products exceeds by far available supply Plasma for fractionation available in industrialized countries to cover their needs Alternatives to plasma products are not sufficiently available, or even not existent hemophilia: recombinant products are expensive; gene therapy still experimental normal immunoglobulin should cover the wide range of antigens (e.g. pathogens) prevailing in a population; specific immunoglobulins can be sourced only in immunized populations 7 | HSS/EMP/BPB: Teheran, Oct 08 Plasma safety and availability: Plasma Safety in highly regulated countries highly regulated countries Commitment of health politicians, strong regulation, reinforcement and continuous surveillance by authorities Commitment of blood services and plasma fractionators GMP implementation in manufacture of all blood plasma derived products No documented virus transmission by plasma products licensed within this regulatory framework > 10 years Blood plasma products needs covered 8 | HSS/EMP/BPB: Teheran, Oct 08 Plasma ««unused» Plasma unused »for forfractionation: fractionation countries with poor or limited regulations Quality criteria for plasma for fractionation not met GMP has not been a natural background for blood transfusion Sensitivity of blood transfusion services to independent regulatory control Need to strengthen experience & regulation of plasma and plasma products Lack of government awareness: rationale for regulation Lack of technical capacity of regulatory authorities 5.8 million liters not recovered in developing countries (Burnouf, 2007) 9 | HSS/EMP/BPB: Teheran, Oct 08 Achilles Project: Project: Rationale Achilles Rationale Blood plasma products in the WHO Essential Medicines List but no access to these products by developing countries because of: 1. Poor quality and safety of plasma (destroyed) 2. Need for introduction of blood products regulations 3. The Achilles project considers upgrading of plasma quality as the driving force for implementation of a safe blood program. 4. The project includes elements of quality, safety and economical benefits. 5. May attract more efficiently the attention of the authorities 10 | HSS/EMP/BPB: Teheran, Oct 08 AchillesConclusion: Project: Rationale Use of local plasma to improve supply of plasma products in developing countries, a legitimate option Compliance with GMP, a key issue for successful PCF Build-up technical expertise of local NRA and plasma supplier is a need Common GMP standards, a basis for mutual recognition of quality standards and inspections results between NRA's Independent regulatory systems for blood products regulation need to be established or strengthened in developing countries Adoption of a Regional/International GMP standard facilitates regional collaboration between NRAs and implementation of PCF 11 | HSS/EMP/BPB: Teheran, Oct 08 Good Manufacturing Practices (GMP): an essential tool for improvement of safety GMP implementation in Blood/Plasma Establishments: a key element to Quality and safety of plasma for fractionation Plasma contract fractionation programs Supporting access to blood plasma products 12 | HSS/EMP/BPB: Teheran, Oct 08 TRACEABILITY FROM DONOR TO PATIENT Blood/Plasma donation Blood Components DONATION INFORMATION Patients Plasma for Fractionation Plasma-Derived Medicinal Product COMPONENTS PREPARATION FRACTIONATION VIRAL INACTIVATION GMP LOOK BACK SYSTEM 13 | HSS/EMP/BPB: Teheran, Oct 08 TREATMENT Plasma for Fractionation* WHO and Plasma for Fractionation a biological product inherent variability Quality of blood/ plasma is dependent on collection, preparation, testing , storage and transport Quality of plasma for fractionation influences the range, quantity, quality, and safety of plasma derivatives WHO Recommendations for the Production, Control and Regulation of Human Plasma for Fractionation (adopted in November 2005) www.who.int/medicines * WHO Technical Report Series 941, Annex 4: 56th WHO Expert Committee on www.who.int/bloodproducts Biological Standardization, 24-28 October 2005. 14 | HSS/EMP/BPB: Teheran, Oct 08 Assuring Blood/Plasma Safety: “Layers of Safety” 1. Donor selection criteria (epidemiological data) 2. Deferral procedures: national registries to avoid use of collections from previously unsuitable donors 3. Laboratory testing for infectious disease markers: selection of kits and validation 4. Implementation of GMPs in blood/plasma collection establishments 15 | HSS/EMP/BPB: Teheran, Oct 08 Plasma Contract Fractionation Programs (Need for GMP implementation) GMP- common principles Quality Assurance Program PLASMA SUPPLIER FRACTIONATOR across countries 16 | HSS/EMP/BPB: Teheran, Oct 08 GMP Licensing Nat.Reg.
