NEWTON, Mass., June 2, 2025 /PRNewswire/ -- GV20 Therapeutics (GV20), a clinical-stage AI-powered biotherapeutics company, today announced that Dr. Kristopher Wentzel from the Angeles Clinic and Research Institute presented updated clinical and translational data of GV20-0251 monotherapy from the ongoing Phase 1/2 clinical trial evaluating GV20-0251 in patients with advanced solid tumors resistant to anti-PD(L)1 and other standard therapies (NCT05669430) at the American Society of Clinical Oncology 2025 Annual Meeting. GV20-251 is the first clinical stage, AI-designed antibody therapeutic against an AI-predicted target in the clinic.
The presentation highlights favorable safety profile, promising monotherapy efficacy, substantial immune activation, and desirable pharmacokinetic properties in patients with advanced solid tumors.
Key highlights from the presentation:
Favorable safety profile
No dose-limiting toxicity up to 20mg/kg, highest dose tested
All treatment-related adverse events (TRAEs) are grade 1 or 2, except 1 grade 3 TRAE
Monotherapy efficacy
3 confirmed partial responses and 3 more with tumor shrinkage (ORR 33.3%, DCR 66.7%) observed in 9 patients with cutaneous melanoma with primary resistance to anti-PD1
2 of the 3 partial responders have liver metastasis with 1 on treatment > 14 months
Additional tumor shrinkage in non-small cell lung cancer and cervical cancer
Translational insights
Linear PK with T1/2 of 26 days and full target occupancy observed with top two dose levels
Substantial immune activation with increased T and NK cell infiltration observed with treatment, consistent with the mechanism of action and preclinical findings

ABOUT GV20 THERAPEUTICS
GV20 Therapeutics is a clinical-stage biotech company dedicated to developing next-generation cancer biotherapeutics. GV20's AI-driven STEAD platform integrates massive B cell repertoire data, -omics data, and advanced AI models to provide deep insights into the tumor microenvironment and uncover targets and therapeutic antibodies that elude other approaches. GV20's pipeline includes best-in-class and first-in-class monoclonal and bispecific antibodies, as well as antibody-drug conjugates (ADCs). The lead program, GV20-0251, is an AI-designed, first-in-class, fully human monoclonal antibody targeting the novel immune checkpoint IGSF8 (Li et al, Cell 2024). GV20-0251 advanced from target discovery to IND in three years, marking a paradigm shift in AI-driven antibody drug discovery. Preclinical studies show that anti-IGSF8 antibodies enhance NK cell cytotoxicity, dendritic cell antigen presentation, and T cell activation, both alone and with anti-PD1. In an ongoing Phase 1/2a trial (NCT05669430) for advanced solid tumors, GV20-0251 demonstrated favorable safety and promising monotherapy efficacy (Wentzel et al, ASCO 2025).
