    Study Title:

    A Phase 1b/2 Multicenter, Open-label Study to Evaluate the Safety and Efficacy of TTI-101 as Monotherapy and in Combination in Participants with Locally Advanced or Metastatic, and Unresectable Hepatocellular Carcinoma


    The purpose of this reach study is to evaluate the safety of TTI-101 when given either alone or in combination treatment, and to see if it will help in the treatment of liver cancer.


    Primary- - To evaluate the safety and tolerability of TTI-101 orally administered as a single agent to participants with locally advanced or metastatic, and unresectable HCC. - To determine the MTD and/or RP2D of TTI-101 as a single agent. Secondary- - To assess the preliminary efficacy of TTI-101 as a single agent in participants with locally advanced or metastatic, and unresectable HCC. - To assess additional efficacy endpoints. - To characterize the plasma PK of TTI-101 following oral administration. - To determine the pharmacodynamics of TTI-101 following oral administration.

These herbal medications include but are not limited to St. John's wort, kava, ephedra (mahung), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto, and ginseng.
