This document summarizes key findings from the AIDS 2018 conference regarding contemporary management of HIV. It describes studies showing:
1) No linked HIV transmissions occurred in over 77,000 condomless sex acts when the HIV+ partner had an undetectable viral load in the PARTNER2 study.
2) On-demand PrEP was highly effective at preventing HIV in several studies when adherence was high.
3) Early results from the ANRS Prevenir study found no difference in HIV incidence between daily and on-demand PrEP, with high adherence in both groups.

8. PARTNER2: HIV Risk in Serodiscordant MSM Partners
Multicenter, observational, prospective study of HIV serodiscordant couples in
which the HIV-positive partners received suppressive ART
‒ PARTNER1: 2010-2014 (MSM and heterosexuals)
‒ PARTNER2: 2014-2018 (MSM only)
Primary aim: estimate within-couple HIV transmission risk for serodiscordant MSM
having condomless sex while HIV-positive partner had HIV-1 RNA < 200 copies/mL
‒ No PEP or PrEP use reported by HIV-negative partner
‒ Linked infections established by phylogenetic analysis of HIV-1 pol and env sequences
isolated from plasma or PBMCs

783 MSM couples contributed 1596 CYFU
9. PARTNER2: HIV Transmission
No linked transmissions documented in ~ 77,000 condomless sex acts when
HIV-positive MSM partner suppressed to HIV-1 RNA < 200 copies/mL

23. ARV Surveillance During Pregnancy
Limited data available on safety of ART during pregnancy and lactation
‒ Approximately 5-yr mean lag between ARV approval and availability of data in
pregnancy, with no pregnancy data available for 3/7 ARVs approved since 2010
Current data on newer ARVs (ie, INSTIs, ETR, TAF) insufficient to exclude
even a 2-fold increase in overall birth defects or rare events such as neural
tube defects
Risk of serious birth defects associated with any drug exposure
at conception greater than for exposure during pregnancy, although clinical
trials may not distinguish between the two
‒ Neural tube defects likely to occur before Day 28 post conception

Primary endpoint: no infusion-related AEs or vedolizumab-related serious AEs before or after ART
interruption
Secondary endpoint: no difference in plasma viral rebound necessitating ART restart* with
vedolizumab vs historical untreated controls through Wk 48
‒ HR: 0.95 (95% CI: 0.42-2.13)
‒ Historical untreated control data from published studies of ART interruption for post hoc analysis

*ART restart criteria: > 4 wks of HIV-1 RNA > 1000 copies/mL, decrease in CD4+ cell count by > 30% from baseline or decrease to
< 350 cells/mm3, HIV-related symptoms, or pregnancy.
61. Summary
PARTNER2 provides evidence that U(ndetectable) does indeed equal
U(ntransmittable)
ANRS Prevenir provides additional data on efficacy of on-demand PrEP
‒ More data to come
DTG has been shown to maintain levels throughout pregnancy and rapidly reduce
HIV-1 RNA
‒ Important safety signal (neural tube defects) when taken at the time of conception
Novel strategies for treatment-naive and treatment-experienced patients continue
to expand
‒ Demonstrated efficacy, safety of 2-drug regimen of DTG + 3TC in treatment naive
The search for innovative strategies for HIV cure continues
