Teropavimab
Based on 1 Customer Validation
Teropavimab (3BNC117-LS) is a broadly neutralizing antibody targeting the CD4-binding site of the HIV-1 envelope. Teropavimab binds to the CD4-binding site of HIV-1 gp120 to neutralize viruses, including multidrug-resistant HIV-1. Teropavimab can be used in studies related to HIV-1 infection and multidrug-resistant HIV-1 infection.

Teropavimab (3BNC117-LS) (50 μg/mL) neutralizes 77.78% of PBMC-derived primary HIV-1 clade A, C, and D isolates with a geometric mean IC50 of 3.62 μg/mL in TZM-bl cells[1].
Teropavimab (3BNC117-LS) neutralizes pseudotyped SHIVAD8-EO in TZM-bl cells with an IC50 of 0.09 μg/mL, exhibiting activity equivalent to native 3BNC117[2].
Teropavimab neutralizes replication-competent SHIVAD8-EO in TZM-bl cells with an IC50 of 0.11 μg/mL, exhibiting activity equivalent to native 3BNC117[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Teropavimab (7.5 mg/kg; s.c.; single dose, administered in combination with 10-1074-LS) confers protection against repeated low-dose mucosal SHIVAD8-E0 challenge in rhesus macaques, with a median time to virus acquisition of 20 weeks[2].

Animal Model:Macaca mulatta (Indian genetic origin, 2-4 years of age, negative for MHC alleles Mamu-A01, Mamu-B08, and Mamu-B17)[2]
-
Dosage:20 mg/kg
-
Administration:i.v.; single dose
-
Result:Delayed median time to virus acquisition to 17 weeks (range 11-23 weeks).
Reduced serum concentrations to undetectable levels between weeks 16 and 22 in five of six recipients; one recipient had undetectable levels by week 5 due to anti-antibody responses.
Achieved a median serum-neutralizing activity of 1:2,538 at 1 week post-infusion.
Extended median serum half-life to 2.8 weeks, a 2.0-fold increase compared to native 3BNC117.
Confirmed significantly greater resistance to SHIVAD8-E0 acquisition compared to untreated controls (P = 0.004).

Result:Delayed median time to virus acquisition to 20 weeks (range 15-24 weeks for five of six macaques).
Reduced serum concentrations to undetectable levels between weeks 5 and 9 in five of six recipients; one recipient maintained measurable levels until week 18.
Induced anti-Teropavimab antibodies in four of six macaques 4 to 6 weeks post-administration, leading to rapid clearance of the antibody.
Confirmed significantly greater resistance to SHIVAD8-E0 acquisition compared to untreated controls (P = 0.004).
