1. www.global-campaign.org Topical Microbicides: New Hope for Non-Condom Prevention of HIV and other STDs Your name here on behalf of the Global Campaign for Microbicides www.global-campaign.org

2. The Global Challenge AIDS kills more people than any other infectious disease -in Botswana, 36% of all adults are infected. -in Sub-Saharan Africa, 67% of the almost 9 million HIV  youth (15-25 years) are female HIV is rapidly becoming a “women’s epidemic” -of every 10 people newly infected with HIV, 6 are women -even in the developed world, rates of new infections among women are rising

3. www.global-campaign.org What is a microbicide? Microbicides are substances that can reduce the transmission of HIV and other STD pathogens when applied vaginally and, possibly, rectally. Currently, they are topical products formulated as gels or creams applied with an applicator. Future formulations could include sponges, time-released vaginal rings or gels combined with barrier devices such as diaphragms or cervical caps.

4. www.global-campaign.org What would they be like? Some will also prevent pregnancy Others will be microbicidal but not contraceptive Many candidate products are broad spectrum reducing risk of some other STDs, in addition to HIV

5. www.global-campaign.org How would they benefit HIV+ women? Reduce risk of re-infection with other HIV strains Help protect their partners -- that is, bi-directional effect Reduce risk of other STDs, yeast and bladder infections Increase chances of getting pregnant safely and having HIV negative babies

6. www.global-campaign.org Microbicides & anal sex The biological challenge of creating an effective rectal microbicide is more complicated Many people (women and men) need microbicides for anal sex We must ensure that vaginal microbicides are accurately labeled – because some people will think of trying to use them that way

7. www.global-campaign.org How effective will they be? First microbicides will be 40-60% protective Second generation products will be 60-80% should be promoted as an adjunct or “back- up” to condoms, not as a replacement use with harm reduction messages, such as: –Use a male or female condom every time you have sex; if you absolutely can’t use a condom, use a microbicide –Use a microbicide with your condom for added pleasure and protection

8. www.global-campaign.org How microbicides are developed Kill or inactivate the pathogen –disrupt the surface membrane –create an inhospitable environment for the pathogen Create a barrier between pathogen and vulnerable tissue –Coat mucous membranes with gel

9. www.global-campaign.org Mechanisms of Action Interfere with fusion of virus to target cell

10. www.global-campaign.org Mechanisms of Action Prevent replication once virus has entered the cell –Anti-retrovirals applied topically Boost vagina’s natural defenses –Defensins, antibodies Combination approach

13. www.global-campaign.org Are they only tested on women? Men are enrolled in some trials: - Baseline studies on the impact of anal intercourse on body -“Male tolerance” studies (impact of candidate microbicides on penis & urethra) -Rectal safety studies being designed

15. www.global-campaign.org Development will require significant government investment Large pharmaceutical companies have relatively little interest in pursuing microbicides -perceived low profitability -liability concerns -lack of in-house expertise -uncertain regulatory environment For the last 20 years, almost all funding for contraceptive development and related research has come from governments and foundations.

16. www.global-campaign.org Funding realities and needs Pharmaco-Economic Analysis showed: Discovery through Phase II costs about $10 mil Phase III trials can cost an additional $46-50 mil If existing portfolio were owned by a single Pharmco, it would need to invest roughly $775 million over the next five years to ensure success BUT, at 2002 levels, only $230 million available from governmental and philanthropic grants Therefore, $500 million shortfall at least !

17. www.global-campaign.org The Advocates’ Message There is a broad-based, demonstrable demand for user-controlled prevention methods North American and European Union investment in microbicide research and development should be -substantially increased in the coming year, and -raised annually until first products reach the market. Without this investment, we may not see user- controlled HIV prevention tools available within this decade.

18. www.global-campaign.org Global Campaign for Microbicides Unifying umbrella for NGO activism and interaction with scientific community 25 active partner organizations; 200 endorsing groups worldwide Served by two secretariats with small core staffs – one in Washington and one in London Centralized fundraising and financial support to partner groups International steering committee

20. www.global-campaign.org Microbicide Development Act of 2003 (S. 859) Will authorize funding increases as needed Will require the NIH to: - establish a branch dedicated to microbicide research -- thus creating a single line of administrative accountability for progress - expand and coordinate the research efforts of all the federal branches working on microbicides (NIH, CDC and USAID)
