Brief Summary:
This study is an open-label, multicenter study to evaluate the efficacy and safety of TT-00420 tablet in adult patients with advanced cholangiocarcinoma.

Condition or disease Intervention/treatment Phase
Cholangiocarcinoma FGFR2 Fusion FGFR2 Gene Mutation FGFR1 Alteration FGFR3 Alteration Drug: TT-00420 Phase 2

Detailed Description:
This is a Phase II, open-label study to evaluate the efficacy and safety of TT00420 in patients with advanced/metastatic and surgically unresectable cholangiocarcinoma (CCA) with 1) FGFR 2 fusions who failed prior FGFR inhibitor treatment, 2) FGFR2 fusions who responded on prior FGFR inhibitor treatment, 3) with other FGFR alterations, or 4) whose tumors do not contain a detectable FGFR alteration.

  4. Progression Free Survival (PFS) (All Cohorts) [ Time Frame: From first study drug administration until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months ]
  5. Disease Control Rate (DCR) (All Cohorts) [ Time Frame: Through study completion, an average of 9 months. ]
    Defined as CR + PR + stable disease (SD)

  6. Overall Survival (OS) (All Cohorts) [ Time Frame: From first study drug administration until the date of death from any cause, assessed up to 24 months ]
  7. Number of Participants With Abnormal Laboratory Values and/or Adverse Events That Are Related to Treatment (All Cohorts) [ Time Frame: Up to 30 days from study discontinuation ]
    As assessed per CTCAE version 5.0

  8. Concentration of TT-00420 at Protocol-Specified Timepoints (All Cohorts) [ Time Frame: From Cycle 1 to Cycle 4, an average of 4 months (each cycle is 28 days) ]

Other Outcome Measures:
  1. Genetic Alteration Status [ Time Frame: Through study completion, an average of 9 months ]
    Evaluation of biomarkers, including but not limited to, FGFR mutation status
