Non-human primate studies on the use of bnAbs to target, control and potentially eliminate the viral reservoir.
SHIV | ART initiation | BnAb | Additional Interventions | Outcome | |
---|---|---|---|---|---|
Nishimura et al. (67) | SHIVAD8-EO | No ART | 3BNC117 + 10-1074 at days 3, 10 and 17 PI | Viral control in 3 of 6 animals from intra-rectal and 3 of 7 animals from intravenous inoculation | |
Nishimura et al. (68) | SHIVAD8-EO | 2 weeks post infection | 3BNC117 + 10-1074 alone at weeks 2, 4 and 6 PI or ART initiation at week 2; 3BNC117 + 10-1074 at weeks 9, 11 and 13; ART discontinuation at week 10 |
Viral control in 4 of 6 animals in bnAb alone arm in 3 of 6 animals in bnAb and ART arm | |
Borducchi et al. (69) | SHIVSF162P3 | 7 days post infection | PGT121 | TLR7 agonist | No rebound in 5/11 animals and delay in rebound when compared to controls (112 vs 21 days) |
Hsu et al. (70) | SHIV1157ipd3N4 | 2 weeks post infection | PGT121 + N6-LS | TLR7 agonist | Delay in rebound when compared to controls (6 versus 3 weeks) |
Barouch et al. (71) | SHIVSF162P3 | 12 months post infection | PGT121 or its FC modified version (GS9721) | TLR7 agonist | No rebound in 7/17 animals |
Whitney et al. (72) | SHIVAD8 | ~50 days post infection | 3BNC117 + 10-1074 | IL-15 superagonist | No difference in time to rebound. Post-rebound control in 6 of 8 animals |
Barouch et al. (73) | SHIVSF162P3 | 9 days post infection | PGT121 | TLR7 agonist, Ad26/MVA vaccine | 4 of 12 PGT121+TLR7 agonisttreated animals and 4 of 10 Ad26/MVA vaccine+PGT121+TLR7 agonist-treated animals did not rebound post treatment interruption. Only 4 of 10 Ad26/MVA vaccine+PGT121+TLR7 agonist-treated animals remained viremic 140 days post treatment interruption. |
