  1. Bridging the gap between research, MCC approval and public access to tenofovir gel Quarraisha Abdool Karim on behalf of the CAPRISA 008 & CAPRISA 009 teams Parliamentary Portfolio Committee on Science & Technology 5 June 2013, Cape Town 1

  2. Tenofovir Gel since CAPRISA 004: Next Steps • Confirmatory Trial – FACTS 001 • For MCC & FDA approval and licensure • Manufacture – ProPreven • Normative Guidelines (WHO/UNAIDS draft) • Implementation • CAPRISA 008 – integration into family planning services • CAPRISA 009 – treatment outcomes in women with HIV • Preparing for Public Access • Toolkit development for providers and users • Community Advocacy Efforts 2

  3. Why does HIV continue to spread in South Africa? Seroprevalence of HIV infection in rural South Africa 10 Male AIDS 1992, 6:1535-1539 Female Quarraisha Abdool Karim, Salim S.

  4. High rates of HIV among key populations: young women in Africa HIV in 15–24 year men and women (2008–2011) Young women have up to 8 times more HIV than men Zimbabwe Source: Adapted from UNAIDS 2012 4

  7. Key Goals of CAPRISA 008 • Provide post-trial access to tenofovir gel for HIV uninfected CAPRISA 004 study participants and community volunteers (UNAIDS Guidance point 19) • Develop and assess an implementation model for tenofovir gel provision through family planning services - Quality Improvement Model - Comprehensive SRH services 3. Collect additional safety data on tenofovir gel 7

  8. CAPRISA 008: Implementing tenofovir gel in family planning clinics • Tenofovir gel provided by Family Planning service nurses with • DMPA, oral contraceptive and other method users – tenofovir gel provided every 3 months • For Nur-isterate users – tenofovir gel provided every 2 months 8

  9. Components of the Toolkit • Providers, Users, Marketing & Demand Creation • Providers • “How to” Training Manual – SRH service provision to include tenofovir gel • Clinic procedures and systems to: • Monitor safety, pregnancy and HIV • Drug accountability & AE reporting • Counseling and support aids • Key information for M&E • Management of post-PrEP infection 9

  10. Current status of CAPRISA 008 • First participant enrolled on November 5, 2012 • 425 participants screened; 359 enrolled and in follow-up • 43% of women enrolled are CAPRISA 004 high adherers • 54/516 women from CAPRISA 004 became infected prior to initiation of CAPRISA 008 • 10.5% seroconversion rate • Incidence rate of 3.8/100wy 10

  11. Goal of CAPRISA 009 • Follow-up of HIV infected participants from CAPRISA 004 (control & intervention arm) to compare: • Disease progression • Therapeutic outcomes using a tenofovir containing treatment regimen • Monitor drug resistance • Target population: • 119 seroconvertors at end of CAPRISA 004 • 54 post-004 seroconvertors • Seroconvertors in CAPRISA 008 11

  12. Current status of CAPRISA 009 • All seroconvertors who agree are in follow-up and care in CAPRISA 002/ Acute Infection Study until ARV treatment eligible • First patient initiated on ARV treatment in CAPRISA 009 in June 2011; • 34 initiated on ARV treatment • 15 from the tenofovir gel arm • 6 month treatment success rate – 88.9% 12

  13. Summary • CAPRISA 008 provides an opportunity to generate evidence for implementation that will be required when a licensed product is available • Inclusion of research naïve volunteers from community completes ethical obligations and adds value to experience • CAPRISA 009 will provide additional safety data post-infection following exposure to tenofovir and provide data on concerns about drug resistance and therapeutic options for post-PrEP seroconvertors • Toolkit based on experiences and outcomes from 008 and 009 will enable rapid introduction and scale-up of a licensed product 13

  14. Conclusions • Tenofovir gel potentially adds a new approach to empower women to take control of their own risk of HIV infection • CAPRISA 004 is the first step – it is likely that with time other products and formulations will surpass tenofovir gel • Post-trial access of tenofovir gel through CAPRISA 008 provides an opportunity to generate evidence for implementation that will fast track the timelag between potential licensure and public access 14
