Linkage Analysis 39 transmission events were included in the April 28 th DSMB report. Linkage analysis was performed to identify the subset of transmission events where the index participant was the likely source of the partner’s HIV infection.

Data Included in this Presentation The DSMB report included 28 linked transmission events. Those data were used to analyze the impact of immediate ART on HIV prevention. One additional linked transmission event was identified after the DSMB meeting. This additional event was in the delayed ART arm, further strengthening the association between immediate ART and HIV prevention.

Initial Linkage Assessment 26 events analyzed were clearly linked using both methods – those 26 events were classified as linked The linkage status of 12 events could not be definitively determined

Next Generation Sequencing One additional event was confirmed to be linked by next generation sequencing after the April 28 th DSMB meeting. This event was in the delayed study arm, further strengthening the association between immediate ART and HIV prevention. This partner seroconverted ~1 month after the index started ART. The partner was most likely infected shortly before the index started ART, or shortly after the index started ART before the index was virally suppressed.

Summary of Linkage Analysis 29 linked events In 2 cases, linkage was only apparent using next generation sequencing 1 immediate ART arm; 28 delayed ART arm 7 unlinked events 4 immediate ART arm; 3 delayed ART arm

Conclusions We used a combination of laboratory and statistical methods to determine the linkage status of transmission events in HPTN 052 These data were used to identify the endpoints used in the analysis of HIV prevention in the HPTN 052 trial A manuscript describing the analysis of HIV linkage in HPTN 052 is In Press in the Journal of Infectious Diseases
