About Protagonist Therapeutics
Protagonist Therapeutics is a clinical development-stage biopharmaceutical company that utilizes a proprietary technology platform to discover and develop novel peptide-based drugs to address significant unmet medical needs. Its primary focus is on developing potential first-in-class oral targeted therapy-based peptide drugs that work by blocking biological pathways that are currently targeted by marketed injectable antibody drugs. Lead peptide candidates, PTG-100 and PTG-200, are based on this approach.
