Improving women's reproductive health through expanding access to key health technologies
For maximize impact, new RH product introduction requires:
• Clear and understood health needs • Safe and effective product/approach • Demonstrated pilot project success • Health systems strengthening • Engagement of and support among stakeholders at various levels • Global and regional advocacy
Introducing new interventions or products for maximum impact Advocate for evidence based change Assess needs Involve stakeholders Build capacity Monitor quality Maximize impact Disseminate lessons and tools Harmonize with communities and existing health care systems Design and implement interventions Evaluate acceptability and performance
Burden of women’s RH health includes
• 122 million women (1/3 are women 15-24 yr old) have an unmet need for contraception • 37 million HIV+ people worldwide; females make up over 60 percent of HIV+ 15-24 year olds; 75 percent in sub-Saharan Africa • 500,000 maternal deaths occur each year (70,000 from unsafe abortion) • Almost 500,000 new cases of cervical cancer each year, 85 percent in the developing world
New and/or underutilized RH technologies and interventions
• Microbicides • Female barrier methods • Emergency contraception • Cervical cancer prevention strategies
1. Microbicides: search for a safe & effective STI protection product
S ubstances that reduce risk of transmission of HIV, STI pathogens when applied vaginally and, possibly, rectally
Current research -
gels or creams applied with an applicator
Future formulations -
sponges, time released vaginal rings, gels combined with cervical barrier devices
Potential public health impact
If a 60% effective product, offered to 73 lower income countries, is used by 20% people reached by health care, during half of unprotected sex acts
2.5 million HIV infections would be averted in 3 years
The product pipeline
5 products Laboratory Testing 2 - 6 Years 2 products 10 - 20 products 10 products Phase I (safety) Phase II (safety) Phase III (effectiveness) 1 - 6 Months 25 - 40 people Up to 2 Years 200 - 400 people 3,000 - 10,000 people Simultaneous studies: HIV+, penile & rectal 2 - 4 Years 10 or more years
What do these trials cost?
Laboratory Testing Phase I (safety) Up to $13 Million Phase II (safety) Phase III (efficacy) Up to $50 Million

2. Female condoms: build broad stakeholder support and launch large scale demonstration projects
• Only female-initiated method currently available for STI prevention, available in over 100 countries • As effective as a male condom for pregnancy and STI prevention, and acceptable to many couples • But…12 million FC distributed annually compared to 6 to 9 billion male condoms
Existing Products
Why not more widely used?
• Lack of political will and donor support • Acceptability issues with first-generation product • Stigma (identified with sex workers) • Product cost, limited product options • Social context of women's lives (gender issues, ability to negotiate use, access)
How to increase impact
• Advocacy to boost funding for introduction so women’s protection is a viable option • Fund demonstration projects to answer ongoing questions about impact and acceptability • Develop collaborations to share research and program tools • Accelerate development and approval of next-generation female condoms
PATH Woman’s Condom: Performance Objectives
• Easy to handle and insert • Easy to use (especially for new users) • Stable during use • Comfortable for both partners • Easy to remove • Less expensive than current options
PATH Woman’s Condom
• Soft-cling foam ellipses provide stability and comfort for a wide range of users • Insertion “capsule” makes insertion easy
3. Emergency Contraception: build awareness and systems support
• Emergency contraception is more effective the sooner it is taken, up to 120 hours after unprotected intercourse.
1 • Progestin-only regimen reduces pregnancy risk 89% • Combined estrogen/progestin regimen reduces pregnancy risk 75% 2 1. Von Hertzen, H. et al. Low dose mifepristone and two regimens of levonorgestrel for emergency contraception: a WHO multicentre randomized trial.

Lancet

Emergency Contraceptive Pills (ECPs)
ECPs can prevent unintended pregnancy, BUT Due to low awareness: • ECP product availability is restricted • Health providers don’t offer it to clients • Women don’t know to ask for it
Systems support: pharmacies as alternative providers of RH needs
• Experience in Cambodia, Kenya, and Nicagagua: • Pharmacy staff are key primary health providers 1 • Clients appreciate easy access • Pharmacy schools and networks support offering RH services 1 Data from Food and Drug Administration, Ministry of Public Health, Thailand says that 70% of patients receive services from drugstore.

Increase ECP access through building awareness
Communicate key messages to 3 key audiences: • Evidence-based safety and effectiveness information for policy and decision makers • Technical information and counseling skills for health providers and program managers • Where to find and how to use ECPs for women who need them.

Findings
• Demand for cervical cancer prevention services is strong among women and communities.
• Organized prevention programs are feasible and can be integrated with existing services.
Findings
• Test characteristics of HPV testing and visual-screening approaches are acceptable in a range of settings.
• Cryotherapy is safe and effective, and can be delivered by mid-level providers.
Findings
The single-visit screen-and-treat approach is safe and effective in low resource settings. This is a major paradigm shift in cervical cancer prevention.
HPV vaccine news headlines
• “Vaccine prevents most cervical cancers.” - New York Times, October 7, 2005.
• Vaccine proves 100 percent effective in preventing cervical cancer – Seattle Times, October 6, 2005.
• “Promising new vaccines could wipe out cervical
cancer. But they must be administered to preteens, and some groups oppose that.” – Philadelphia
Inquirer, July 4, 2005.
• “OK Roll up your sleeve; new vaccines are arriving
but the economics are still a challenge” –Business
Week, July 25, 2005.
The HPV-cervical cancer link
• Human papillomavirus (HPV) is a very common infection (more than 50% of adults get it, in most it is a transitory infection).
• 99.7% of cervical cancer cases are associated with HPV.
• Progression from HPV infection to cancer usually takes 20-30 years.
• Currently, there is no treatment for HPV infection.
Global distribution of HPV types in cervical cancer 14% 3% 6% 9% 15% 53% HPV 16 HPV 18 HPV 45 HPV 31 HPV 33 HPV others
HPV
vaccine opportunity
• 2 vaccines protecting against HPV 16 and 18 are nearing licensure.
• Both have high efficacy in Phase II trials and appear very safe.
• Phase III trials will involve over 50,000 women worldwide.
• Both manufacturers express interest in serving developing country markets.
But….
Can vaccines be made broadly accessible to the young women who need them the most, given challenges around product supply, information needs, delivery system weaknesses, and community awareness?
PATH’s HPV vaccine focus
