Study summary

This is a multicenter, non-randomized, umbrella, open-label phase II clinical study, aiming to observe and evaluate, as well as explore the efficacy and safety of precision targeted therapy based on NGS technology for IDH1-mutated patients, specifically the combination of ivosidenib with multi-target tyrosine kinase inhibitors represented by lenvatinib or PD-1/PD-L1 in advanced biliary tract cancer patients who have failed systemic chemotherapy.

Interventions

  • DrugIvosidenib

    Oral, selective, small-molecule inhibitor of the mutant isocitrate dehydrogenase 1 (IDH1) enzyme. Administered at a dose of 500 mg, taken orally once daily. This is the core investigational drug in all study arms.

  • DrugLenvatinib

    Oral, multi-targeted tyrosine kinase inhibitor. Administered at a weight-based dose (8 mg for body weight \<60 kg or 12 mg for body weight ≥60 kg), taken orally once daily. Used in combination arms.

  • BiologicalPD-1/PD-L1 inhibitor

    Intravenous immune checkpoint inhibitor. Specific agent (e.g., Pembrolizumab, Durvalumab, Toripalimab, or Tislelizumab) may be chosen based on local availability and patient access. Administered at standard doses (e.g., 200 mg, 1500 mg, or 240 mg) via IV infusion every three weeks. Used in combination arms.

What researchers measure

Primary outcomes

  1. Objective Response Rate (ORR)

    Time frame: From first dose of study drug until disease progression, death, or start of new anti-cancer therapy, assessed up to approximately 24 months.

Secondary outcomes

  1. Disease Control Rate (DCR)

    Time frame: From first dose of study drug until disease progression, death, or start of new anti-cancer therapy, assessed up to approximately 24 months.

  2. Progression-Free Survival (PFS)

    Time frame: From first dose of study drug until disease progression or death from any cause (whichever occurs first), assessed up to approximately 24 months.

  3. Overall Survival (OS)

    Time frame: From enrollment (or first dose) until death from any cause, assessed up to approximately 36 months.

  4. Duration of Response (DOR)

    Time frame: From the date of first documented response (CR or PR) until the date of disease progression or death, assessed up to approximately 24 months.
