IAVI

• International, scientific, non for profit organisation– HQ New York– European offices in Amsterdam, working space in Brussels– Offices in Nairobi and New Delhi

• IAVI’s mission is – To accelerate the development of a safe and effective

preventive AIDS vaccine and to ensure that once is available it will be readily accessible, especially to those most in need

IAVI: Strategies• Accelerate R&D

• Promising candidates clinical trials in the South

• Mobilise public support to AIDS vaccines• Awareness, information, political lobbying

• Facilitate the involvement of the private sector• Preserving social objectives (proprietary arrangements)

• Prepare global access to AIDS vaccines• Key part of the comprehensive response against HIV/AIDS

Global effort Alliances

IAVI: Key Driving Ideas• Look for alliances

• North and South; public and private

• Create the conditions to conduct sustainable clinical research in, for and with the South

• R&D and development agendas

• Prepare for success NOW

IAVI: Sources of Funds • Governments (~ 66%)

• Canada, The Netherlands, UK, US, Denmark, Sweden, Norway, Ireland

• Multilateral (~ 3%)• World Bank

• Private Foundations (~ 30%)• Bill & Melinda Gates, Rockefeller, Alfred P. Sloan, Starr

• Private sector (~ 1%)• Becton, Dickinson and company

IAVI: Expenses 1996-2008• R&D 77%

• Advocacy work 11%

• Administrative and general costs 8%

• Fundraising 2%

• Political lobbying 2%

IAVI’s European NGO Partners• France: AIDES• United Kingdom: National AIDS Trust• Netherlands: AIDS Fonds• Denmark: AIDS Fondet• Germany: Deutsche AIDS Stiftung • Spain: gTt• Sweden: Noah’s Ark• Belgium: Sensoa*

* Currently in preparation

Working with NGO partners• Information, education, awareness

• Partner´s and/or IAVI´s tools• Multilingual work a must

• Political work• Several levels (regional, national, EU, global)• Great diversity in-between countries

HIV vaccines approachesrecombinant protein

synthetic peptides (V3)

naked DNA

Viral, bacterial vectors

whole-inactivated virus

live-attenuated virus

What and to Whom?• A preventive AIDS vaccine will be given to people uninfected with HIV to train their immune systems to prevent infection or AIDS • There is no chance of any preventive vaccine

now in clinical trials causing HIV infection because they contain only synthetic copies of portions of the virus, not the virus itself

Stages of vaccine researchPre-clinical

• Biological idea/concept

• Laboratory development• Construction of product GLP• In parallel manufacturing (GMP); animal

testing

• Animal testing• Toxicity, immunogenicity• GLP and GMP identical

Stages of vaccine researchClinical

• Phase I, preliminary– n=dozens; low risk of contracting HIV; safety

• Phase II, intermediate– n= hundreds; low and higher risk of contracting

HIV; more safety, immunogenecity, dosage, administration

• Phase III, advanced– n= thousands; high risk of contracting HIV

infection; efficacy vs. placebo
