TMB-365/TMB-380 (TMB-365 and TMB-380 combination)

Dual Antibody Combination of TMB-365 with TMB-380


With broad efficacy over clades of prevalent HIV-1 variants and the long in vivo lifetimes or PK half-life, long acting, of TMB-365 and TMB-380, the dual antibody combination of TMB-365 with TMB-380, like their peers, also dual antibody combination 3BNC117 and 10-1074, are approached for HIV-1 therapy and/or prophylaxis purposes. [1, 2, 3]  The TMB-365 and TMB-380 combination is designated for the treatment of HIV-1 in virologically suppressed patients. [4, 5]
