Shattuck Labs, Inc. is a biotechnology company specializing in the development of potential treatments for inflammatory and immune-mediated diseases. It is engaged in developing a potentially first-in-class antibody for the treatment of inflammatory bowel disease and other inflammatory and immune-mediated diseases. Its lead product candidate, SL-325, is a monoclonal antibody that is designed to bind to death receptor 3 (DR3) and inhibit its interaction with its ligand, TL1A. TL1A is a costimulatory ligand in the tumor necrosis factor superfamily, which activates immune responses through binding a single receptor, DR3. It is conducting a Phase I clinical trial in healthy volunteers. It is also developing SL-425, a half-life extended version of SL-325. It is also developing multiple preclinical DR3-based bispecific antibodies, which are designed to inhibit both the DR3/TL1A axis and another biologically relevant target for the treatment of patients with inflammatory bowel disease.
