14 The Quad Pill Quad: elvitegravir, cobicistat, tenofovir, and emtricitabine versus Atripla: efavirenz, tenofovir, and emtricitabine At 48 weeks, rate of undetectable HIV was 90% for the quad pill and 83% for Atripla Quad: atazanavir/cobicistat, tenofovir, and emtricitabine versus Atazanavir/ritonavir, tenofovir, and emtricitabine At 48 weeks, rate of undetectable HIV was 86% for atazanavir/cobicistat and 82% for atazanavir/ritonavir Source: Elion R, et al. ICAAC 2010; Abstract H-938b.

15 The Quad Pill Adverse Events Adverse event rate similar but slightly lower for quad pill versus Atripla 46% compared with 57% In the booster study, adverse events were noninferior between the two arms, at 36% and 48% Source: Elion R, et al. ICAAC 2010; Abstract H-938b.

16 TMC278 Two trials, THRIVE and ECHO, with 1,368 treatmentnaive patients TMC278 versus efavirenz Pooled 48-week data: 84.3% of TMC278 patients had undetectable HIV, compared with 82.3% of efavirenz patients TMC278 better when viral load <100,000 copies Fewer adverse events with TMC278: 16% versus 31% (P<0.0001) Fewer dropouts because of toxicity for TMC278: 3% versus 8% (P=0.0005) Rimsky L, et al. ICAAC 2010; Abstract H-1810.

17 Darunavir 590 treatment-experienced patients 800 mg/day versus 600 mg BID Each dose boosted with 100 mg ritonavir 48 weeks: 72.1% on daily dose and 70.9% on twice-daily dose had fully suppressed HIV One patient with virologic failure developed resistance Lathouwers E, et al. ICAAC 2010; Abstract H-1811.

18 Vicriviroc 218 treatment-naive patients Vicriviroc versus tenofovir/emtricitabine 48 weeks: vicriviroc response rate 76%, compared with 83% for tenofovir/emtricitabine Statistically noninferior Dunkle LM, et al. ICAAC 2010; Abstract H-938a.

19 Veteran Testing In 2006, the CDC recommended expanded routine testing for HIV in people up to age 64 The Veterans Administration was able to eliminate written informed consent Subsequent national survey of veterans receiving care in VA health centers HIV testing very low 5.7 million outpatients treated in % tested for HIV in 2009 Only 9.2% have ever been tested Welch M, et al. IDSA 2010; Abstract 1063.

20 Rapid HIV Testing in Jails Washington, DC: 14% of inmates tested before program introduced, 79% in 2009 Philadelphia: 10% tested before program, 69% in 2009 Baltimore: 0.4% tested before program, 22% from May 2008 through April 2009 Similar prior success in Rhode Island: 15% of all new HIV cases identified during the same time period Beckwith C, et al. IDSA 2010; Abstract 1068.

21 Treatment Initiation Lags Retrospective analysis of records In 2008, one-third of patients with HIV not treated Half had indication for therapy under guidelines (CD4 count under 350) 75% would be eligible under current guidelines (CD4 count under 500) Dombrowski J, et al. IDSA 2010; Abstract 809.

22 Treatment Initiation Lags In 2008, cohort included 4,765 patients, 77% of whom had been on antiretroviral therapy and 23% antiretroviral-naïve Of naïve patients, 439 had CD4 counts below 350 cells/microliter, 336 were between 351 and 500, and 331 had counts greater than 500 cells/ microliter Depending upon the institution, the percentage of HIV patients currently on antiretroviral therapy ranged from 60% to 78% Dombrowski J, et al. IDSA 2010; Abstract 809.

23 Experience Improves Outcomes Retrospective analysis of more than 12,000 patients Chance of undetectable HIV 44% higher if physician practice included more than 100 patients Overall, 81.1% of patients controlled virus Horberg M, et al. IDSA 2010; Abstract 1131.

24 Summary At the end of this activity, participants should understand: l l l details of new drugs presented at ICAAC, including the quad pill with cobicistat and TMC278 once-daily dosing of darunavir in treatmentexperienced patients why vicriviroc is no longer under development

25 Summary At the end of this activity, participants should understand: l l l l HIV testing remains low in the VA system rapid testing and the jail system lags in treatment initiation the effect of provider experience on patient adherence
