Ivosidenib in Locally Advanced or Metastatic Cholangiocarcinoma With IDH1 R132 Mutation After at Least One Prior Systemic Treatment - an Observational Study

Ivosidenib in Locally Advanced or Metastatic Cholangiocarcinoma With IDH1 R132 Mutation After at Least One Prior Systemic Treatment - a Prospective, Multicenter, Observational Study in Germany

Cholangiocarcinoma is a rare and aggressive tumor of the bile duct associated with a poor prognosis and very limited treatment options. The IDH1 inhibitor ivosidenib provides a new, targeted treatment option for this disease. Ivosidenib was approved by European Medicines Agency (EMA) in May 2023 as monotherapy in adult patients with locally advanced or metastatic cholangiocarcinoma with an IDH1 R132 mutation who were previously treated by at least one prior line of systemic therapy.

The prospective, multicenter, observational study IDHIRA will collect first real-world data on ivosidenib treatment in a broad patient population in Germany. Ivosidenib will be administered according to the current SmPC. Thus, IDHIRA will generate real-world evidence on effectiveness, quality of life (QoL) and safety of ivosidenib.

Inclusion Criteria:

• Age 18 years or older.

• Histologically confirmed locally advanced or metastatic CCC with a documented IDH1 R132 mutation diagnosed by an appropriate diagnostic test

• Patients must have at least one prior systemic therapy

• Signed written informed consent before or within 6 weeks of first ivosidenib dose (inclusion of patients up to 6 weeks after first ivosidenib intake is allowed for patients not participating in the PRO module)

• For patients participating in the PRO module (optional):

  • Dated signature of informed consent form before start of study treatment.
  • Willingness and capability to participate in PRO assessment in German language.

• Other criteria according to current SmPC.

Exclusion Criteria:
