Silverback Therapeutics, Inc. is a clinical-stage biopharmaceutical company based in Seattle, Washington, focused on developing tissue-targeted therapeutics for cancer, chronic viral infections, and other serious diseases. The company's lead product candidate, SBT6050, is currently in a Phase I/Ib clinical trial. It is a TLR8 agonist linker-payload conjugated to a HER2-directed monoclonal antibody, specifically targeting tumors such as breast, gastric, and non-small cell lung cancers. Additionally, Silverback is advancing SBT6290, a preclinical candidate that targets Nectin4, expressed in various cancers, and SBT8230, aimed at treating chronic hepatitis B virus infection. Utilizing its proprietary ImmunoTAC technology, Silverback aims to develop a new generation of therapies that can be systemically delivered yet act locally at disease sites, thereby modulating critical disease pathways that were previously considered inaccessible.
