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

The Need for New TB Drugs
• Complex 6-9 months treatment with a 4 drug combination regimen
• No new anti-TB drug in over 40 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

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

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)
![Page 7: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/7.jpg)
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

• Discovered by Pathogenesis, Inc.
• Distinct mechanism of action
• Potent activity against both active and slow growing M.tb.
• Possesses both bactericidal and sterilizing activity
![Page 15: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/15.jpg)

![Page 16: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/16.jpg)
Bayer HealthCare
• Moxifloxacin - fluoroquinolone antibiotic
• Orally active
• Once-a-day dosage
• Marketed in 141 countries for the treatment of several acute respiratory and uncomplicated skin and soft tissue infections
![Page 17: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/17.jpg)
Moxifloxacin for TB
• Novel mechanism of action: kills M.tb. by inhibition of DNA gyrase
• In vivo mouse studies showed that moxifloxacin reduced treatment time by two months when substituted for isoniazid
• Safe to use with antiretroviral agents since it is not metabolized by the cytochrome P-450 enzyme system
![Page 18: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/18.jpg)
The Partnership
• Clinically assess the efficacy and safety of moxifloxacin as a front-line agent for the treatment of TB
• If clinical trials are successful, register moxifloxacin for a TB indication
• Committed to making the product affordable and accessible to patients in the developing world
![Page 19: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/19.jpg)
Moxifloxacin Clinical Trials
• Evaluate whether substitution of moxifloxacin for one of the standard TB drugs (isoniazid or ethambutol) eliminates TB infection faster than current standard therapy
• Trials to be run in Brazil, Canada, South Africa, Spain, Tanzania, Uganda, the United States and Zambia
• More than 3,000 TB patients will be enrolled
![Page 20: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/20.jpg)
Bayer Commitments
• Donate moxifloxacin for each clinical trial site
• Cover costs of regulatory filings
• Provide moxifloxacin at an affordable price for patients with TB in the developing world
![Page 21: PDPs and Alternative IP Management/Tech Transfer Strategies for Improved Global Health](https://reader036.vdocuments.net/reader036/viewer/2022081520/5681548f550346895dc29ffe/html5/thumbnails/21.jpg)
TB Alliance Commitments• Coordinate and help cover the costs of the
clinical trials• Ensure coordination of information and
results towards the goal of registration• Leverage substantial support from:
– U.S. Centers for Disease Control and Prevention (CDC)
– Orphan Products Development Center of the U.S. Food & Drug Administration
– European and Developing Countries Clinical Trials Partnership (EDCTP)

GlaxoSmithKline
• Project oversight by Joint Steering Committee• TB Alliance helps to support 25 full-time
scientists at GSK working exclusively on the TB drug program
• GSK absorbs all remaining overhead costs• GSK contributes a matching number of staff• Any resulting medicines will be made affordable
and accessible to those most in need
