Demand for ARV medicines in low and middle income countries will exceed 16 million person-years by the end of 2016 V. Habiyambere, J. Perriëns, B. Dongmo-Nguimfack, World Health Organization On behalf of the ARV Forecasting Technical Working Group UNAIDS, CHAI, UNICEF, Global Fund, PEPFAR (SCMS, USAID), and Futures Institute
WHY ? • ART demand increases year by year • production capacity needs to keep pace with demand • Global supply security is an issue • 2013: TDF and EFV • 2014: d4T/3TC pediatric formulation outage; ZDV • Manufacturers need independent assessment of what and how much to produce 2-3 years ahead of time
Methods – forecast of total future demand 3-year linear projection of ARV use in annual Global AIDS reporting Limited to 80% of total number of people needing treatment, from UNAIDS/Futures Institute, according to WHO 2013 criteria Arithmetic average 3-year extrapolation of country targets stated in annual WHO survey 3-year linear extrapolation 22 country quantifications by CHAI Stratification: adult/paediatric ARV use
Forecast of adult/paediatric and first/second line treatment (country targets)
Methods – forecasts of market share Annual WHO survey – 16 countries reporting in each year since 2010 Arithmetic Average Global Price Reporting Mechanism – 75% of LMIC procurement lagged 1 year CHAI 21 country 5-year projections PEPFAR 2-3 year quantification - 15 countries Global Fund quantification – 54 countries in 2014 and 30 in 2015
Limitations and next steps • Overlap between data sets • Limited time horizon • No insight on formulation use • New molecules not included • We will expand time horizon to 5 – 7 years • Will drill down to formulation level
But the bottom line is: • We are on track for 15 million by 2015 • New drugs are being introduced and older ones are disappearing • Without significant impact on the cost of ART in LMIC • More on access to ARV drugs (price, regulatory status, API, forecast of use, issues in MIC) on: http://www.who.int/hiv/amds/en/
