Biological Activity: Calotatug ginistinag (XMT-2056) is an antibody-drug conjugate (ADC) targeting HER2, linked to a payload composed of XMT-1519 conjugate-1 (HY-148067) and STING agonist-20 (HY-148068). Calotatug ginistinag activates the STING signaling pathway in tumor cells and tumor-resident immune cells, induces the production of type I interferons and cytokines (CXCL10, IFN-β, IL-6, TNF-α, triggers innate anti-tumor immune responses, and exerts a bystander effect. Calotatug ginistinag exhibits efficacy against HER2-expressing cancer cells in co-culture with PBMCs. Calotatug ginistinag induces tumor regression and reduces systemic inflammation in various tumor models. Combination treatment with Calotatug ginistinag, Trastuzumab (HY-P9907) and T-DXd (HY-138298) yields benefits. Calotatug ginistinag can be used in studies related to HER2-expressing solid tumors such as breast cancer, gastric cancer and ovarian cancer[1][2].
