6 Slide 6 of 11 From MS Saag, MD, at Chicago, IL: May 9, 2016, IAS-USA. Dolutegravir PK IMPAACT P1026s Mulligan N et al. CROI 2016. Poster abstract 398 DTG AUC 25-30% lower in 2 nd /3 rd trimester vs paired postpartum (PP) data. Differences not significant. DTG Cmax significantly lower in 3 rd trimester vs postpartum. C 24 41% lower in 2 nd /3 rd trimester – not significant. 6/9 (67%) women in 2 nd trimester, 12/15 (80%) in 3 rd and 8/9 postpartum had AUC above 10 th percentile (37.5 mcg*hr/mL) of non- pregnant adults. “ AUC and trough exposures appeared to be lower in pregnancy compared to postpartum. But antepartum AUC and trough values still similar to those seen in non-pregnant adults.”

10 Slide 10 of 11 From MS Saag, MD, at Chicago, IL: May 9, 2016, IAS-USA. Change in eGFR (Cockcroft-Gault) with TAF vs TDF Studies 104 and 111: Week 48 Combined Analysis *Cockcroft-Gault (mL/min). -6.6 -11.2 p <0.001 Time (Weeks) Mean (SD) Change from Baseline eGFR*

11 Slide 11 of 11 From MS Saag, MD, at Chicago, IL: May 9, 2016, IAS-USA. Conclusions: Early ART does not seem to be associated with higher mortality in resource rich settings, in contrast to data from resource limited settings Underpowered to provide robust evidence Limitation: lack of data on CM treatment and disease management. We aim to obtain this in the future. Results:  235 patients from 28 cohorts  84% male, median age at CM 38 years.  Death rate at 6 months: 42/235 (18%)  Hazard Ratios (95% CI) for deferred vs early ART  Crude 1.29 (0.68-2.43)  Adjusted 1.30 (0.66-2.55)
