Can treatment be more accessible, affordable, simple and efficient? The right drugs available at the right place and time….

Treatment 2.0 – a programmatic approach TREATMENT 2.0 Adapt delivery systems Mobilize communities POC and other simplified monitoring Optimize drug regimens Reduce costs Five pillars Achieve and sustain universal access & maximize the preventive benefits of ART Simplification Five pillars Achieve and sustain universal access & maximize the preventive benefits of ART Simplification

Reducing costs and increasing sustainability – collaboration? Role for the UN supporting countries on the use of TRIPS flexibilities, access principles – guidelines, policy papers, issues briefs Global mechanisms for IP related issues and access –Medicines Patent Pool – “ up and running” – licensing mechanisms - FDC and optimized Tx options –Ohter initiatives UNITAID, CHAI Local production and regulatory harmonization Upcoming – consultation on pricing in upper middle income countries

Successful country initiatives to cut the costs of ARV Note: (i) At an exchange rate of 7.40 ZAR/USD, the savings amounted to R 4.7 billion. Sources: (ii) Massive reduction in ARV prices. Johannesburg, Government of South Africa, 2010 (www.info.gov.za/speech/DynamicAction?pageid=461&sid=15423&tid=26211, accessed 15 June 2012); (iii) Mutabaazi I.I.

Optimization Strategy RationaleWhat is critically needed Major challenges & risks Fixed-Dose Combinations Combining existing compatible ARV drugs in one pill or co-blister improve adherence and simplify treatment Bioequivalence studies Register results Lab-development and testing Regulatory issues Market fragmentation ARV Dose Reduction A lower dose of a given ARV drug may have the same effect on treating the disease, at lower cost /lower side effects Clinical trials (efficacy) Publish/register results Dosing guidelines Clinical trials very expensive Regulatory issues Ethical concerns Perception concerns Market confusion Reformulation (eg; extended release formulations) New formulation of an existing ARV drug can give equal level of drug in the body/blood, while taking lower dose Bioequivalence studies Register results Dosing guidelines Lab-development and testing Clinical trials less expensive Perception concerns Market confusion New Drugs & Combinations New drug with a different profile will replace a previous component in the drug regimen, with improvement of efficacy, tolerability or convenience Clinical trials (safety and efficacy)Clinical trials very expensive Market fragmentation New ART Strategies (eg: Induction- maintenance) Phased approach with a short/periodic induction using combined ARV drug regimen followed by a long term monotherapy for maintenance after stable viral suppression, with improvement of tolerability, convenience, cost and long term adherence Clinical trials (efficacy)Clinical trials very expensive Ethical concerns Perception concerns Market confusion ART Optimization

Addressing innovation and access to innnovation o Improving effectiveness, tolerability and resilience of 1 st line regimens o Assessing regimen switch needs: PoC VL o New drugs in the pipeline: accelerating entry into market of innovative products o Ensuring competition for innovative products: licensing mechanisms and technology transfer o Global R&D convention?

15
What is needed to meet the challenge of scale up? o Radical simplification (Tx algorithm, drugs, services) o Innovation (in drug design, diagnostics, delivery) – shorten time between development and entry into market – registration… o Efficiency gains – service delivery o Effectiveness and impact – coverage and early diagnosis o Equity and affordability (at individual and system level) o Leadership, willingness and resources to invest
16
What do we stand for? o “No one being left behind” o Different approaches to coverage – upper middle income countries; key populations, etc o No double standards o Simpler to use, less toxic, heat stable drugs are good for patients no matter where they live o People live long and better lives o Early diagnosis. Earlier treatment initiation(?) o Better drugs and monitoring kits o …………..
