Protagonist's research has shown that oral treatment with PTG-200 significantly improves disease outcomes in an animal model of colitis through specific inhibition of the IL-23R signaling pathway. Moreover, treatment-related responses from biomarkers profiled in this research, including biomarkers identified and tracked in blood, feces, and/or colon biopsies, provide a potentially valuable way of assessing mechanism-specific and disease-related parameters, as well as demonstrating clinical effect in human trials.
"We are very pleased to receive this grant, which recognizes the considerable benefit that could be provided by biomarkers of IL-23R signaling activity in IBD," said
"This award will help us further develop accessible and measurable biomarkers that are useful for understanding the ability of our oral peptide agents to target and modulate the activity of IL-23 receptors in the gastrointestinal tract, for demonstrating early pharmacodynamic activity in human trials, and for choosing the appropriate dose ranges of such agents for clinical development in IBD," said

Protagonist Therapeutics is a clinical-stage biopharmaceutical company with a proprietary technology platform which is utilized 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. Protagonist's initial lead peptide product candidates, PTG-100 and PTG-200, are based on this approach, and the company believes these candidates have the potential to transform the existing treatment paradigm for inflammatory bowel disease (IBD), chronic gastrointestinal diseases consisting primarily of ulcerative colitis and Crohn's disease.
PTG-100, a potential first-in-class oral peptide alpha-4-beta-7 integrin antagonist, is currently in a global Phase 2b clinical trial for moderate-to-severe ulcerative colitis. PTG-200, a potential first-in-class oral Interleukin-23 receptor antagonist for potential treatment of IBD, initially Crohn's disease, is currently in pre-clinical development and is expected to enter Phase 1 clinical studies in the second half of 2017.
In addition to PTG-100 and PTG-200, the company is developing an injectable hepcidin mimetic PTG-300 as a potential orphan drug for the treatment of rare diseases such as beta-thalassemia. PTG-300 is currently in pre-clinical development and is expected to enter Phase 1 clinical studies in the second quarter of 2017.
Protagonist is headquartered in Newark, California with its pre-clinical and clinical staff in California, and discovery operations both in California and in Brisbane, Queensland,
