1 Prequalification of HIV/AIDS Drugs - UN joint activity lPartners* –UNAIDS –UNICEF –UNFPA –WHO –With the support of World Bank lWHO –Manages, provides technical support/assistance based on WHO norms and standards, plus ICH and other standards, where applicable. PQ team independent.

2 Prequalification basic principles Voluntary for participating manufacturers Legitimate - General procedure and standards approved through WHO Expert Committee system Widely discussed in many fora –FIP Congress, Nice 2002 –Supported by ICDRA in 2002 and 2004, representing more than 100 national drug regulatory authorities –WHA resolution (May 2004) Transparent (information on the web site Open to both innovators and multisource/generic manufacturers No cost for applicants so far

3 General procedure: Pre-qualification Steps of the Procedure –1. Invitation for EOI (public, drug lists) –2. Guidelines for product dossier compilation –3. Receiving submissions (dossiers) –4. Screening of dossiers –5. Dossier evaluation (WHO Manual+guidelines) –6. Site inspection (GMP, GCP, GLP) –7. Reports and outcome (compliance/add info?) –8. Pre-qualification results (web) –9. Testing of samples Re-qualification (3 years)

4 EOI HIV and related diseases NNRTIs NRTIs PIs Anti-infectives (antibacterial, antimycobacterial, antiprotozoal, antiviral, antifungal) Anticancer FDCs (Lam/Stav, Lam/Zid, Lam/Stav/Efavir, Lam/Stav/Nevir, Lam/Zid/Efavir, Lam/Zid/Nevir)

5 General procedure: Pre-qualification What will be required (1) ? –1. Details of the product –2.Regulatory situation in other countries –3. Active pharmaceutical ingredient (s) (API) –3.1 Properties of the API –3.2 Sites of manufacture –3.3 Route(s) of synthesis –3.4 Specifications (API described/not described in a pharmacopoeia) –3.5 Stability testing –WHO Expert Committee on Specifications for Pharmaceutical Preparations, Thirty-fourth report. Geneva, World Health Organization, 1996: (WHO TRS, No 863)

6 General procedure: Pre-qualification What will be required (2)? –4. Finished product –4.1.Formulation –4.2. Sites of manufacture –4.4. Manufacturing procedure –4.5Specifications for excipients –4.6Specifications for the finished product –4.7Container/closure system(s) and other packaging –4.8Stability testing

7 General procedure: Pre-qualification What will be required (3)? –4.9Container labelling –4.10Product information –4.11Patient information and package inserts –4.12Justification for any differences to the product in the country or countries issuing the submitted WHO-type certificate(s) –4.13Interchangeability (bio-equivalence studies) –4.14Summary of pharmacology, toxicology and efficacy of the product

8 Access to HIV/AIDS Drugs of Acceptable Quality What are the technical difficulties and problems experienced or revealed as a result of pre-qualification? Quality of product dossiers varied -Lack of information regarding API, validation, specifications, bio-equivalence -DRAs not applying same standards as recommended by WHO, yet products are registered and used -Very few substances and products have Pharmacopoeia monographs -What standards to apply? If standards not available - full assessment necessary

9 Access to HIV/AIDS Drugs of Acceptable Quality Difficulties and problems (cont) Manufacturing site inspections -Manufacturers not ready -Upgrading of facilities to comply with WHO GMP -DRAs issued CPP – yet non-compliance -Inspections reveal non-compliance, e.g. antibiotics (penicillin), hormones and other products manufactured in the same site -No validation

10 The prequalification part of the project has two major activities: countries are providing expertise I. Assessment of products dossiers i.e. quality specifications, pharmaceutical development, bioequivalence etc. : Brazil, Canada, Denmark, Estonia, Finland, France, Germany, Hungary, Indonesia, Malaysia, Philippines, Spain, South-Africa, Sweden, Switzerland, Tanzania, Zimbabwe... II. Manufacturing site inspections: teamwork of inspectors: WHO representative (qualified GMP inspector), inspector from well- established inspectorate (Pharmaceutical Inspection Convention Scheme countries) and national inspector(s): Canada, France, Italy, Switzerland, The Netherlands … Quality control analysis - upon need but not always necessarily before prequalification and supply, increasingly as part of follow-up
