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

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.
