Figure 1. Delayed viral rebound with 3BNC117 and 10–1074 combination therapy during ATI.
a, Study design. Red and blue triangles represent 3BNC117 and 10–1074 infusions, respectively. b, Plasma HIV-1 RNA levels (black; left y-axis) and bNAb serum concentrations (3BNC117, red; 10–1074, blue; right y-axis) in the 9 bNAb-sensitive participants (left) and the 2 participants with pre-existing resistance against one of the antibodies (right). Red and blue triangles indicate 3BNC117 and 10–1074 infusions, respectively. Serum antibody concentrations were determined by TZM-bl assay. Grey shaded areas indicate time on ART. Lower limit of detection of HIV-1 RNA was 20 copies/ml. c, Kaplan-Meier plots summarizing time to viral rebound for the participants with HIV-1 RNA < 20 copies/ml 2 weeks before and at the start of ATI (n=11, left), for the participants sensitive to both antibodies (n=9, center), and for the participants that showed pre-existing resistance to one of the antibodies (n=2, right). Y-axis indicates percentage of participants that maintain viral suppression. X-axis indicates weeks after start of ATI. Participants receiving the combination of 3BNC117 + 10–1074 are indicated by the blue line. Dotted red lines indicate a cohort of individuals receiving 3BNC117 alone during ATI9 (n=13) and dotted black lines indicate a cohort of participants who underwent ATI without intervention10 (n=52).
