Email Address About Protagonist TherapeuticsProtagonist Therapeutics (NASDAQ:PTGX) (NASDAQ: PTGX) is a clinical-stage biopharmaceutical company focused on the development of novel, orally administered peptide-based therapies for immune-mediated and other serious diseases. The company leverages its proprietary Peptide 2.0 platform to design peptides that target G protein–coupled receptors and cytokine receptors, with the goal of combining the potency of biologics with the convenience of oral administration. Protagonist’s approach aims to address unmet medical needs in areas where injectable therapies have been the standard of care. Among its lead programs is PTG-100, an oral α4β7 integrin antagonist intended to block leukocyte migration to the gut in ulcerative colitis and Crohn’s disease. PTG-200, a selective interleukin-23 receptor antagonist, is in Phase 2 clinical trials for moderate to severe Crohn’s disease. The company’s PTG-300 program is a hepcidin mimetic being evaluated in hematologic disorders characterized by iron overload, including polycythemia vera and myelofibrosis. Founded in 2006 and headquartered in San Diego, California, Protagonist Therapeutics conducts global clinical trials across North America, Europe and Asia. The company is led by a team of seasoned biotechnology executives with deep expertise in peptide drug discovery and development. Protagonist maintains collaborations with academic institutions and industry partners to advance its pipeline and explore additional therapeutic areas where oral peptide therapeutics may deliver significant patient benefit.View Protagonist Therapeutics ProfileRead more More Earnings Resources from MarketBeat Earnings Tools Today's Earnings Tomorrow's Earnings Next Week's Earnings Upcoming Earnings Calls Earnings Newsletter Earnings Call Transcripts Earnings Beats & Misses Corporate Guidance Earnings Screener Earnings By Country U.S. Earnings Reports Canadian Earnings Reports U.K. Earnings Reports Latest Articles Tesla Earnings Loom: Bulls Eye $600, Bears Warn of $300Spotify Could Surge Higher—Here’s the Hidden Earnings SignalBerkshire-Backed Lennar Slides After Weak Q3 EarningsWall Street Eyes +30% Upside in Synopsys After Huge Earnings FallRH Stock Slides After Mixed Earnings and Tariff ConcernsCelsius Stock Surges After Blowout Earnings and Pepsi DealWhy DocuSign Could Be a SaaS Value Play After Q2 Earnings Upcoming Earnings Fastenal (10/13/2025)BlackRock (10/14/2025)Citigroup (10/14/2025)The Goldman Sachs Group (10/14/2025)Johnson & Johnson (10/14/2025)JPMorgan Chase & Co.
