Biological Activity
Human IgG1 kappa
Simlukafusp alfa (FAP-IL2v) shows binding affinity constants of 43±9 pM, 80±20 pM, 660±80 pM, 0.3 nM, 0.23 nM and 0.5 nM with huIL-2Rβγ, cyIL-2Rβγ, muIL-2Rβγ, huFAP, cyFAP and muFAP, respectively[1].
Simlukafusp alfa (0-100 nM; 5 days) activates CD4+/CD8+ T cells and NK cells in vitro, but not preferentially Tregs[1].
Simlukafusp alfa (0-100 nM) enhances Cetuximab (HY-P9905)-mediated antibody-dependent cellular cytotoxicity (ADCC) and Cibisatamab (HY-P99011)-mediated T-cell-dependent cellular cytotoxicity (TDCC) in vitro[1].

Animal Model:huCD16-transgenic SCID mice, lung orthotopic xenograft A549 model[1]
-
Dosage:1 mg/kg in combination with 25 mg/kg Cetuximab (HY-P9905) as single agents
-
Administration:IV, weekly starting at Day 14 for 4 weeks
-
Result:Achieved greater tumor control than either agent given as monotherapy. Reduced tumor volume and tumor growth.
-
Animal Model:CD-1 mice[1]
-
Dosage:1, 2 or 4 mg/kg
-
Administration:IV (Pharmacokinetic Analysis)
-
Result:Pharmacokinetic parameters after first dose of human FAP-IL2v (huFAP-IL2v) in CD-1 mice
CD-1 mice (n=10 per group) were given 1, 2, and 4 mg/kg huFAP-IL2v by IV administration once weekly. Multiple IV doses at 1 and 2 mg/kg were administered QW for up to a maximum of three doses, at which point toxicity was observed. Only a single dose was administered to the 4-mg/kg IV treatment group because of toxicity in these treatment groups. Blood was sampled at 0.5, 6, 24, 48, 72, and 168 h.
