Overview

GI-102 + pembrolizumab is an investigational combination therapy for advanced or metastatic solid tumors. GI-102 is a novel bi-specific Fc fusion protein that combines the CD80 ectodomain with an interleukin-2 (IL-2) variant, attached via a human IgG4 Fc region. The CD80 component targets tumor and immune cells, blocks CTLA-4 on regulatory T (Treg) cells, and inhibits PD-L1 via CD80, while the IL-2 variant stimulates NK and CD8+ T cell proliferation with reduced Treg impact by abolishing IL-2Rα affinity. Pembrolizumab is a well-established anti-PD-1 monoclonal antibody (marketed as KEYTRUDA) that inhibits the PD-1 immune checkpoint pathway, restoring T-cell antitumor activity. This combination is being clinically investigated for immunotherapy-resistant solid tumors, especially metastatic liver cancer, melanoma, and renal cell carcinoma[1][2][3][4][5].
