Towards a new treatment Era ? When to start (1) The game changers
When to start ART ? Three recent Randomized Control Trial HPTN052: Cohen, NEJM 2011; 365:493-505 HPTN052: Grinsztejn, Lancet Infect Dis 2014; 14:281-90 TEMPRANO: TEMPRANO study group, NEJM 2015; 373:808-22 START: INSIGHT START study group, NEJM 2015; 373:795-807 All three trials had the same objective: To compare the efficacy of "early ART" vs. "deferred ART" in reducing severe morbidity* in adults with high CD4 counts** * Severe morbidity included all-cause death, tuberculosis, AIDS and non-AIDS cancers in the three trials **Baseline CD4 counts: HPTN052 350-550 /mm3 TEMPRANO 250-800 /mm3 START >500/mm3
HPTN052 Participants: 1761 54% in Africa (East/Southern) • TEMPRANO • Participants: 2056 • 100% in Africa (West) START Participants: 4651 21% Africa (mostly East/southern)
Hazard Ratio of severe morbidity : TEMPRANO 0.56 (0.41-0.76) N Engl J Med 2015;373:808-22.
Hazard Ratio of severe morbidity: START 0.43 (0.30-0.62) N Engl J Med 2015; 373:795-807.
Hazard Ratio of severe morbidity Hazard Ratio of HIV transmission HPTN052 0.73(0.52-1.03) 0.04 (0.01-0.27) N Engl J Med 2011; 365:493-505 Lancet Infect Dis 2014; 14:281-90
Towards a new treatment Era ? When to start (1) No more double standard in international guidelines ?

When to start in the guidelines When to start in the field ? 1. Empower physicians to follow international guidelines
Movement to ‘Treat All’ happening Policy uptake for adults and adolescents, July 2016 • 24% of all LMIC and 40% of fast track countries have adopted Treat All • By the end of 2016, more than half of all LMIC and 80% of fast track countries will have adopted Treat All With the courtesy of M. Doherty
Policy uptake to full implementation, July 2016 • Implementation is just getting underway and the majority of countries have not yet fully put the policy into practice for Treat All With the courtesy of M. Doherty

When to start in the guidelines When to start in the real life ? 2. No more limitation in financial resources
Percentage of African national budgets allocated to health - 2010 < 10%(n=19 [44.2%])
≥15% (n=4 [9.3%]) <15% (n=20 [46.5%])
The funding gaps The funding GAPS 44/97 countries (%) , ART funding Gap exceeds 55% of the total resource requirements Dutta A, et Al, Plos Med, 2015
How limited financial ressourcesdangerouslyimpact clinical pratices Inadequate forecasting & supply... • Lack of ARV drugs • More patients in advanced stage • Need to prioritize
NEW REVISED NEW DIRECTIONS IN WHEN TO START NEW
