Global Tuberculosis Epidemic • One-third of the world’s population is infected with Mycobacterium tuberculosis (M. tb. ) – 2 billion people • 8 -9 million develop active disease annually • 2 million deaths occur each year – 1 person dies every 15 seconds • 400, 000 cases of MDR-TB each year • Leading cause of death in HIV-positive people – 12 Million people are TB/HIV co-infected TB’s economic toll: $16 billion a year

Current TB Drug Therapy • Active TB – Standard therapy – 4 drugs (isoniazid, rifampin, pyrazinamide & ethambutol) for 2 months, followed by isoniazid and rifampin for 4 months • Latent TB – Standard therapy – isoniazid for 9 months • Multi-Drug Resistant TB (MDR-TB) – Individualized, prolonged therapy, few available drugs, poorly tolerated and difficult to administer • TB/HIV Co-Infection – Treatment as in active TB, but drug interactions with antiretroviral agents make simultaneous therapy difficult • Extensively Drug Resistant TB (XDR-TB) – No treatment available

The Need for New TB Drugs • Complex 6 -9 months treatment with a 4 drug combination regimen • No new anti-TB drug in over 50 years • TB/HIV co-infections fueling each other • MDR-TB is on the rise • Unattractive market for private sector • No capitalization of public sector research

History of the TB Alliance • Cape Town Declaration – February 2000 – Hosts: Rockefeller Foundation and the Medical Research Council of South Africa – Over 120 organizations (health, science, philanthropy and private industry) • Results – Support goals of Stop TB Initiative – Create Scientific Blueprint – Develop Pharmacoeconomic Analysis Build a Global Alliance for TB Drug Development

The TB Alliance • Independent, international Product Development Partnership founded in October 2000 • Non-profit organization • Headquarters in New York City – Offices in Brussels and Cape Town • Entrepreneurial, virtual R&D approach – Out-source R&D to public and private partners • Pro-active fundraising – Over US $200 million raised • Support ~ 200 FTE worldwide and 50 FTE in-house

Our Mission • Develop an entirely new therapeutic regimen that will shorten or simplify the treatment of tuberculosis • Coordinate and act as catalyst for global TB drug development activities • Ensure Affordability, Adoption and Access (AAA Strategy)

AAA Strategy • Affordability – Appropriate pricing in developing countries • Adoption – Ensure that new drugs are incorporated into existing treatment programs • Access – Procurement and distribution to those patients who need them most

Our Vision FDC s 10 Days 2 Months 6 Months

Profile of a New TB Drug • • • Shorten treatment to less than 2 months Novel mechanism of action (MDR/XDR-TB) Orally active Once daily or intermittent therapy Compatible with HIV treatment Low cost of goods

Financial Support • Bill and Melinda Gates Foundation • Rockefeller Foundation • Netherlands Ministry for Development Cooperation • United States Agency for International Development (USAID) • Governments of Great Britain and Ireland

Types of Deals • • • In-Licensing IP Assignment Sponsored R&D Collaborative R&D Freedom to Operate Clinical Trials
