a, Flow diagram indicating the selection of study participants. b, Table showing individual participant demographics and baseline clinical characteristics. * EVG – elvitegravir, cobi - cobicistat, TDF - tenofovir disoproxil fumarate, FTC - emtricitabine, RPV - rilpivirine, EFV - efavirenz, TAF - tenofovir alafenamide fumarate, D, RTV – ritonavir, ABC – abacavir, 3TC - lamivudine, DTG – dolutegravir. ** NNRTI-based regimens were switched four weeks before ART interruption due to longer half-lives of NNRTIs. *** Pre-screening of bulk outgrowth virus obtained from PBMC culture by TZM-bl assay. # All participants harbored clade B viruses. Viral load < 20 D: Plasma HIV-1 RNA detected but not quantifiable by clinical assay. Dx, diagnosis; Scr, screening; Wk −2, week −2; d0, day 0. Grey shaded rows indicate participants who were found to have detectable viremia (HIV-1 VL > 20 copies/ml) at week −2 or day 0. These participants were not included in the efficacy analyses given lack of viral suppression at baseline.
