R&D for TB: Updates & Opportunities for the Private Sector GBC Conference on TB, TB/HIV co-infection & Global Fund Partnership - Johannesburg, October 11-13, 2010 Christian Lienhardt Senior Scientific Advisor, Stop TB Partnership WHO, Geneva
Contents Context/Scene-Setting Brief “pipeline update” Role of PDPs in R&D Advocacy for TB R&D: what can the private sector do?
The global burden of TB in 2008 Estimated number of cases Estimated number of deaths 1.9 million (range 1.6–2.3 million) 9.4 million (range 8.9–9.9 million) All forms of TB HIV-associated TB 1.4 million (15%) (1.3–1.6 million) 520,000 (0.45–0.62 million) Multidrug-resistant TB (MDR-TB) 440,000 (0.39-0.51 million) 150,000 (0.05–0.27 million)
West Pacific 20% Africa 31% Americas 3% SE Asia 34% East Mediterranean 7% Europe 5% Estimated TB Incidence rates, 2008
TB Control Global Targets 2015:Goal 6: Combat HIV/AIDS, malaria and other diseases Target 8: to have halted by 2015 and begun to reverse the incidence… Indicator 23: incidence, prevalence and deaths associated with TB Indicator 24: proportion of TB cases detected and cured under DOTS 2015:50% reduction in TB prevalence and deaths relative to 1990 levels 2050: elimination (<1 case per million population)
A new strategy requires a new plan… The Global Plan 2011-2015 strengthens the fight The Global Plan 2006-2015 defines direction and costs 9.8 billion US$ to develop new tools 11 billion US$ to develop new tools
Today's tools for TB control are old tools – a struggle to cut deaths by half by 2015 and eliminate TB by 2050 VACCINE DIAGNOSTIC TREATMENT BCG Developed 1920s 1st-line TB drugs Discovered 1943-1970 Sputum smear microscopy Discovered 1882
Innovative action needed in 4 spheres"Moving beyond the TB box"

Advocacy for TB R&D: what can the private sector do? direct investment in R&D patronage/sponsoring university research support innovative starts-ups (venture capital funding) Advocate for tax breaks for R&D offer incentives "champions" for promotion of innovation in R&D promote debates and discussions (roundtables)
Conclusion – the TB Research Movement TB Research Movement promotes the need for harmonized and complementary funding of TB research to target revolutionary discoveries that will foster better care and control for the elimination of TB. Development of a consensus-driven Roadmap for International Research to eliminate TB www.stoptb.org/researchmovement/
