Coordinated strategy for tool-directed research Coordination of field site strengthening Diagnostic trial registration and standardization Consensus on phase IV research priorities What’s missing? Designated funding needed for these activities
Total number of countries DOTS expansion has not improved case detection rates No of countries implementing DOTS Global case notification rate (All forms of TB) Global CNR Year Countries Clear need to enhance case detection to attain global TB control targets Source: WHO Report 2003: Global Tuberculosis Control: surveillance, planning, financing.

Recent history of public sector TB diagnostic development • Years of denial: 1975 to 1996 “Microscopy is all we need” • Years of waiting: 1997 to 2003“Facilitating industry will provide the tools” • Years of action: 2004 to 2009“Medical need – evidence – partnership”
Development of new technologies Harvesting the best of both worlds to produce public sector goods Public-private partnership Private sector • Market-driven • Product focus • IP management • Goal-directed R&D • Complex project management • Financing • Manufacture & Distribution • Rigid targets/milestones • Marketing Public sector • Industry model + • Need-driven • Partnership • Needs driven • Altruism • Partnership 1900 1950 2000
FIND will drive diagnostics development from concept to delivery in the health system Upstream FIND’s focus Downstream Demonstration Discovery and research Development Evaluation Market access and distribution Liaise with funders, pharmaceutical and biotech companies, research institutions, academia Liaise with funders, multi-lateral agencies, NGOs,health ministries, and agencies like GDF and GFATM Create network of public and private partners to create effective tests and demonstrate their success Demonstration Large-scale projects measuring feasibility and impact on disease control programs Development Facilitate, co-fund, co-develop Evaluation Regulatory- quality lab & field trials Proof of principle Product in box Efficacy Data Effectiveness Data Policy FIRST BOARD MEETING Geneva, Switzerland

Purpose Test Indications Proposed Priority Case Detection Drug susceptibility testing Latent TB Infection • Detect pulmonary TB with high bacterial load (SS+) • Detect pulmonary TB with low bacterial load (SS -, Cx +) • Detect extra-pulmonary and pediatric TB • Detect MDR-TB for treatment • Detect MDR-TB for surveillance • Detect LTBI for surveillance • Detect LTBI for treatment • # 1 • # 2 • # 3 • # 4 • # 7 • # 5 • # 6 Priority needs for TB diagnostics
easy & robust lab procedures • support for multiple health problems • universal platforms • dedicated POC devices • minimal skill requirements Segmentation - diagnostic question vs. health system level RESOLUTION faster than culture ! DETECTION more sensitive than smear ! FIRST BOARD MEETING Geneva, Switzerland
POSITIVE NEGATIVE Tests that revolutionize patient care or disease control long-term • POC smear replacement • POC culture replacement • 2-day high-TP sensitive lab test for case detection +/- DST for urban centers • 2-day lab-free culture replacement • Specific predictor of progression from LTBI short-term Tests that are significant incremental improvements over existing tools • Improved microscopy • Simplified or speeded culture • Simplified or speeded DST • POC smear supplement 2003 2004 2005 2006 2007 2008
