 as a result of the significant toxicities associated with atezolizumab + bevacizumab standard of care therapy, over 40% of patients experienced treatment interruptions in registrational studies. Similarly, second-line therapies have high rates of discontinuations due to associated severe adverse events. The limited efficacy across a broad patient population, coupled with the advanced stage of disease upon diagnosis, emphasizes the ongoing high medical need for more effective therapies in HCC.

Tvardi’s Solution: TTI-101 for HCC

TTI-101 is designed to deliver therapeutic benefit as monotherapy and in combination with existing approved agents for the treatment of HCC. STAT3 has been shown to be activated in 89% to 100% of patients with HCC samples and correlate closely with tumor vascularity and aggressiveness, and its expression is significantly associated with poor overall survival. The pathogenesis of HCC is mediated by pY-STAT3 through intrinsically increasing tumor cells proliferation and extrinsically playing a major role in immune suppression. Tvardi believes TTI-101 is a novel therapeutic candidate that could offer a much-needed treatment option in HCC.

Preclinical Studies in HCC

Preclinical studies in genetically engineered mouse models replicating NASH-induced HCC demonstrated TTI-101’s potential to reverse inflammation and fibrosis and inhibit tumor growth. In addition, as further described below, HCC models demonstrated the synergistic effect of double and triple combination therapy with inhibition of multiple pathways in HCC, ultimately leading to reduced tumor size, supporting further exploration of TTI-101 in combination with ICIs and anti-VEGF therapies.

TTI-101 Reversed Multiple Pathogenic Steps of Liver Cancer in NASH-induced Mouse Model

Dr. Tweardy and his collaborators at the University of Texas MD Anderson Cancer Center, conducted a preclinical study where TTI-101 was tested in a NASH-induced HCC mouse model. The model replicated the human pathogenesis over a 11-month period, where the livers in mice over that time period developed inflammation and fibrosis and formed tumors. Thereafter, mice were administered TTI-101 or placebo once a day for four weeks. TTI-101 statistically significantly impacted critical STAT3-mediated steps of pathogenesis; specifically, TTI-101 demonstrated statistically significant changes in (1) microsteatosis score (abnormal liver fat accumulation) that was 89% lower in animals treated with TTI-101 versus
