  3. Blood Products & related Biologicals Animal-derived immunoglobulins Anti-rabies Anti-venoms Anti-tetanus toxin Anti-diphteria toxin Anti-botulism toxin Human blood derived products Blood components (red cells, platelets, plasma) Blood Coagulation Factors Polyvalent Immunoglobulins (IV, IM) Specific Immunoglobulins Anti-hepatitis B Anti-rabies Anti-tetanus Anti-rhesus (anti-D) Albumin Other biological productsAnticoagulant & fibrinolysis biological therapeutic products • In vitro biological diagnostic devices (IVDs): Priority: Support of international regulations

  4. Blood Products & related BiologicalsMission (Strategic Plan) A WHO normative programme: WHO is mandated by it's Member States to "…develop, establish and promote international standards for biological products." In practice, biological products cover: Vaccines, Blood and blood products; In vitro biological diagnostic devices; other biological products. An Essential Medicines Programme: To support the achievement of the health related MDGs by assisting governments and organizations to ensure equitable access to effective medicines of assured qualityand their rational use by prescribers and consumers

  5. Blood Products & related Biologicals WHO standard setting functions*: • Develop/establish/provide WHO Biological Reference Preparations • Develop/adopt/provide evidence based WHO Guidelines on Quality Assurance and Control of specific products or procedures • Support enforcement and implementation of WHO Norms and Standards:strengthen technical/regulatory capacity of NRAs & NCLs • Support operational strategies to improve access to quality products (*) Consistent with the WHO mandate through the Expert Committee on Biological Standardization

  6. Blood Products and related BiologicalsTarget Audiencies • National/Regional Regulatory Authorities • National/Regional Control and National/Regional Reference Laboratories • Blood Establishments and Plasma Fractionators • Manufacturers of animal derived blood products • Manufacturers of in vitro diagnostic tests • Public Health Departments/Public Healt Officers/Ministries of Health • Medical Professionals, Health Workers • Procurement agencies and NGO’s

  8. Blood Plasma: a valuable human resource Medicinal products derived from human donations of blood and plasma play a critical role in health care

  9. Blood Products: Life-Saving MedicinesWHA Resolution 63.12 Blood and blood components Whole blood collected into containers, anticoagulant to prevent clotting, cold chain Blood components, obtained from whole blood by separation (centrifuge or apheresis): Red blood cells: Oxygen transport Platelets: Hemostasis, preventing bleeding Plasma: clotting factors, immunoglobulins etc. Cryoprecipitate , FVIII source Plasma derivatives Plasma for "fractionation“, further purification of plasma proteins, e.g. Blood Coagulation Factors, e.g. Factor VIII for treatment of hemophilia A Specific Immunoglobulins, e.g. anti-hepatitis B, anti-rabies, anti-tetanus, anti-D IM and IV normal IgG Albumin, involved in the regulation of body fluids, used for resuscitation

  10. WHO List of Essential Medicines • 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

  11. TRACEABILITYFROM DONOR TO PATIENT Blood/Plasma donation Blood Components Patients Plasma-Derived Medicinal Product Plasma for Fractionation FRACTIONATION VIRAL INACTIVATION DONATION INFORMATION COMPONENTS PREPARATION TREATMENT Good Manufacturing Practices

  12. Assuring Blood/Plasma Safety:“Layers of Safety” 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

  13. 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 *WHO Guidelines available: www.who.int/bloodproducts

  14. Plasma Contract Fractionation Programs(Need for GMP implementation) Nat.Reg. Authority Nat.Reg. Authority PLASMA SUPPLIER FRACTIONATOR GMP- common principles GMP Licensing Quality Assurance Program GMP Licensing across countries

  15. WHO Guidelines and Recommendationshttp://www.who.int/bloodproducts/en/ WHO Guidelines on good manufacturing practices for blood establishments WHO Recommendations for the production, control and regulation of human plasma for fractionation WHO Guidelines on viral inactivation and removal procedures intended to assure the viral safety of human blood plasma products

  16. Overall Goals (WHA Resolution 63.12)The “Achilles” project • To raise quality standards in blood establishments (BE) • To reduce risk of transmission of infectious diseases • Effective regulatory systems for blood products worldwide • To make safe blood products available to patients

  18. Definition of Biologicals (WHO) • Biological sources • Crude, semi purified extracts or purified fractions • of microbial, animal or human tissues Produced by biological processes Traditional/ Recombinant DNA/ Other biological technologies Biological assay - Complex molecular structure- Cannot be characterized by physicochemical criteria alone

  19. WHO Biological Reference Standards*Global measurement standards • Tool for comparison of biological measurement results worldwide • Facilitate transfer of laboratory science into worldwide clinical practice • Underpin apropriate clinical dosage • Facilitate convergence of international regulations (e.g. blood products; blood safety related IVDs) *Established by the Expert Committee on Biological Standardization

  20. WHO Biological Reference Preparations A tool for comparison of results worldwide Regulatory Authorities Manufacturers and Blood Establishments WHO IS/IRP 2ndary Ref. Material Product Users
