Gilvetmab
Based on 1 Customer Validation
Gilvetmab is a canine-derived anti-cPD-1 monoclonal antibody, as well as an immune activator/antitumor agent. Gilvetmab binds to canine PD-1, blocks the interaction of PD-1/PD-L1/L2, prevents immunosuppression, reactivates antitumor responses, induces tumor regression or disease stabilization, and may also trigger pseudoprogression. Gilvetmab can be used in research related to malignant melanoma and mast cell tumors.

Gilvetmab, a canine IgG2κ antibody, fails to support functional binding of adalimumab's variable regions to human TNF-α or canine TNF-α when used as a scaffold for the chimeric antibody Humivet-G1 in vitro[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Gilvetmab (6-10 mg/kg; i.v.; every 14-28 days) demonstrates an objective response rate of 46% and a median time to progression that was not reached in client-owned dogs with stages I-III mast cell tumor, with an acceptable safety profile[4].

-
Animal Model:Client-owned dogs (multiple breeds; 1-16.2 years of age, ≥3 kg body weight; 52% male, 48% female)[4]
-
Dosage:6 mg/kg; 10 mg/kg; 10 mg/kg (escalated after 5 treatments at 6 mg/kg)
-
Administration:i.v.; every 28 days (up to 5 treatments); every 14 days (up to 10 treatments); every 14 days (escalated dose, 5 additional treatments)
-
Result:Achieved an objective response rate (ORR) of 20% (95% CI, 7%-41%), with 2 complete responses (8%) and 3 partial responses (12%).
Observed stable disease in 40% (10/25) of dogs.
Reached a median time to progression (TTP) of 56 days.
Maintained 14% of dogs progression-free at the end of the study.
Exhibited initial tumor enlargement (50% and 92% increase from baseline) followed by regression in 2 dogs receiving 10 mg/kg every 14 days, consistent with pseudoprogression.

Animal Model:Client-owned dogs (multiple breeds; 6.4-13.1 years of age, ≥3 kg body weight; 50% male, 50% female)[4]
-
Dosage:6 mg/kg; 10 mg/kg; 10 mg/kg (escalated after 5 treatments at 6 mg/kg)
-
Administration:i.v.; every 28 days (up to 5 treatments); every 14 days (up to 10 treatments); every 14 days (escalated dose, 5 additional treatments)
-
Result:Achieved an objective response rate (ORR) of 46% (95% CI, 27%-67%), with 2 complete responses (8%) and 10 partial responses (38%).
Observed stable disease in 27% (7/26) of dogs.
Did not reach median time to progression (TTP).
Maintained 39% of dogs progression-free at the end of the study.
Observed responses across all tumor stages (50% ORR for stage I, 33.3% for stage II, 44.4% for stage III).
