(“Tvardi” or the “Company”) (NASDAQ: TVRD), a clinical-stage biopharmaceutical company focused on the development of novel, oral, small molecule therapies targeting STAT3 to treat inflammatory and proliferative diseases, today announced that it will host a KOL webinar on Wednesday, August 19, 2026 at 11:00 AM ET featuring Randy Longman, MD, PhD (Weill Cornell Medicine), who will join Tvardi management to discuss the current treatment landscape in ulcerative colitis (UC) and the persistent unmet needs that remain despite recent clinical advances and currently approved therapies. The event will feature new data from Tvardi and a review of the Phase 1 healthy volunteer results supporting the potential of TTI-109 in UC. The discussion will explore the scientific rationale for targeting STAT3, a convergent node implicated in multiple pathways that contribute to the pathogenesis and persistence of UC. Tvardi management will also discuss the planned clinical development strategy for TTI-109. Dr. Longman will provide his perspective on the clinical relevance of the findings and how a STAT3 inhibitor could ultimately fit within the UC treatment paradigm. A live question and answer session will follow the formal presentations.

Planned UC Clinical Trial Tvardi plans to initiate a study of TTI-109 in patients with moderate-to-severe UC in 2027, subject to clearance of Investigational New Drug (IND) application and additional funding. The primary endpoint will be safety, and the secondary endpoint will be clinical remission at 12 weeks. Exploratory pharmacodynamic endpoints will include serum/tissue biomarkers and analysis of single nucleotide polymorphisms (SNPs). About Tvardi Therapeutics Tvardi is a clinical-stage biopharmaceutical company focused on the development of novel, oral small molecule therapies targeting STAT3 to treat inflammatory and proliferative diseases with significant unmet need. STAT3 is a central mediator across critical signaling pathways that drive uncontrolled proliferation, survival and immune dysregulation. STAT3 is also positioned at the intersection of many signaling pathways integral to the survival and immune evasion of cancer cells. The Company has completed a Phase 1 healthy volunteer study of TTI-109 and plans to initiate a clinical trial of TTI-109 in its initial indication, ulcerative colitis, pending IND clearance and the availability of additional funding. The company is also conducting a Phase 1b/2 clinical trial of TTI-101 in hepatocellular carcinoma <a href="https://www.globenewswire.com/Tracker?data=iY3AFkVUlEPqPhub6b1HW5NghN9cWbkPvV3Y_83dDpj-M15qd8nyhUFLu-PTvtLmPNonWsHIrq1FProlFIF2cPDSmlCdS72XBRrOR0Lm1cA9vfDeNAXnuG8GzZ3S_wPp" rel="nofollow" target="_blank" title="(NCT05440708)">(NCT05440708)</a>.
