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.

Conditions

  • Biliary Tract Cancer

Interventions

DRUG

Ivosidenib

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.

DRUG

Lenvatinib

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.

BIOLOGICAL

PD-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.
