Tvardi’s lead product, TTI-101, is an oral, small molecule inhibitor of STAT3 that specifically blocks pY-STAT3. TTI-101 binds tightly to the SH2 domain of STAT3, which specifically blocks its ability to bind to signaling complexes that contain tyrosine kinases. This is designed to prevent STAT3 from being phosphorylated at tyrosine (Y) 705 and further prevent STAT3 dimerization and nuclear translocation. The selective binding of TTI-101 to the SH2 domain thus inhibits STAT3’s canonical nuclear function, while preserving its essential non-canonical functions associated with cellular respiration within the mitochondria. The FDA has granted orphan drug designation for TTI-101 in both IPF and HCC as well as Fast-Track Designation for TTI-101 in HCC.

TTI-109 is Tvardi’s newest STAT3 inhibitor and has completed IND-enabling studies. TTI-109 is structurally related to, yet chemically distinct from TTI-101, and has demonstrated key characteristics for clinical use including tolerability, bioavailability, and potency.
