Lycia Therapeutics, Inc., a biotechnology company, engages in the discovery and development of therapeutics designed to degrade disease-causing extracellular proteins for the treatment of autoimmune, inflammatory, and allergic diseases. The company develops the LYTAC platform, a modular technology designed to create therapeutics that selectively reduce the levels of pathogenic proteins. Its therapeutic candidate LCA-0061 degrades immunoglobulin E (IgE) for the treatment of allergic diseases, including food allergy. The company also develops LCA-0062, a follow-on program designed to degrade IgE for the treatment of allergic diseases. Additionally, it develops LCA-0321, a candidate designed to selectively degrade TSHR autoantibodies (thyrotropin receptor antibodies, or TRAbs), the pathogenic drivers of Graves' disease.
