GNUV201
GNUV201 is a PD-1 inhibitor with cross-reactivity in humans, mice and monkeys, which effectively blocks the PD-1/PD-L1 interaction. GNUV201 activates T cells and restores their anti-tumor activity, effectively inducing tumor regression. GNUV201 can be used in the research of related diseases such as colorectal cancer, melanoma, pancreatic cancer and colon cancer.

Species Reactivity
Human
In Vitro
GNUV201 and its chimeric precursors bind to CHO cells expressing human PD-1 (EC50=117 pM) and CHO cells expressing mouse PD-1 (EC50=203 pM) with comparable affinities[1].
GNUV201 (15 min, 1 h) blocks the human PD-1/PD-L1 interaction in flow cytometry-based assays with an IC50 of 9.9 nM; it also blocks the murine PD-1/PD-L1 interaction with an IC50 of 6.7 nM[1].
GNUV201 blocks the interaction between human PD-1/PD-L1 in luciferase reporter gene assays, with an IC50 value of 6.3 nM[1].
GNUV201 cross-reacts with mouse PD-1 (EC50=32 pM) and human PD-1 (EC50=28 pM). It has a slower dissociation rate than Keytruda, and exhibits significantly higher binding affinity under acidic pH conditions (Kd=0.9 nM; pH=6.0)[2].

In Vivo
GNUV201 inhibits tumor growth in the MC38/hPD-1 knock-in mouse colon cancer model[2].

Animal Model:C57BL/6 (female, 7 weeks old, subcutaneous implantation of 1×106 MC38 murine colorectal cancer cells)[1]
-
Dosage:1 mg/kg; 3 mg/kg; 10 mg/kg
-
Administration:i.p.; twice weekly; 2-3 weeks
-
Result:Exhibited dose-dependent tumor growth inhibition with 24% TGI at 1 mg/kg, 59% TGI at 3 mg/kg, and 73% TGI on day 15 post-treatment.
Achieved statistically significant improvement in overall survival, with ~20% of mice surviving without tumor growth at 10 mg/kg.
