About this study
Official title: 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free survival (PFS)
PFS is defined as the time interval measured from the day of first ivosidenib administration to first progression or death, whichever comes first. Patients without tumor progression or death at the time of analysis will be censored at their date of last contact.
Measured: max. 38 months (FPI - LPLV)
Secondary outcomes (25)
Overall survival (OS)
OS is defined as the time interval measured from the day of first ivosidenib administration to time of death from any cause. Time to last contact will be used if a patient has no documented date of death and OS for the patient will be considered censored.
Measured: max. 38 months (FPI - LPLV)
Timt to treatment failure (TTF)
TTF is defined as the time interval measured from the day of first ivosidenib until discontinuation of treatment for any reason including progression, toxicity, start of a new antineoplastic therapy, or death, whichever occurs first. Patients dropping out without knowledge of a potential ending of therapy (e.g., lost to follow up) will be censored with the last date of contact.
Measured: max. 38 months (FPI - LPLV)
Overall response rate (ORR)
ORR is defined as the proportion of patients achieving a complete or partial response as best response. Patients without response measurement are considered non-responders.
Measured: max. 38 months (FPI - LPLV)
Disease control rate (DCR)
DCR is defined as the proportion of patients achieving complete response, partial response, or stable disease as best response. Patients without response measurement are considered non-responders.
Measured: max. 38 months (FPI - LPLV)
(Serious) adverse events ((S)AE))
The case- and patient-based incidence of (S)AEs will be provided.
Measured: max. 38 months (FPI - LPLV)
(Serious) adverse drug reactions ((S)ADR) related to ivosidenib
The case- and patient-based incidence of (S)ADRs will be provided.
Measured: max. 38 months (FPI - LPLV)
Adverse events of special interest (AESI)
The case- and patient-based incidence of AESIs will be provided.
Measured: max. 38 months (FPI - LPLV)
Global health-related quality of life during course of treatment
The change from baseline (i.e., difference) in the scales of the EORTC QLQ-C30 (European Organisation for Research and Treatment of Cancer quality of life questionnaire C30) will be displayed for each point in time, using boxplots.
The scales of the EORTC QLQ-C30 range in score from 0 to 100. A high scale score represents a higher response level.
Measured: max. 38 months (FPI - LPLV)
Cholangiocarcinoma-related quality of life during course of treatment
The change from baseline (i.e., difference) in the scales of the EORTC QLQ-BIL21 (European Organisation for Research and Treatment of Cancer quality of life questionnaire BIL21) will be displayed for each point in time, using boxplots.
The scales of the EORTC QLQ-BIL21 range in score from 0 to 100. A high scale score represents a higher response level.
Measured: max. 38 months (FPI - LPLV)
Assessing parameters of physician treatment decision making
Frequencies of distinct impact ratings for parameters affecting ivosidenib therapy choice will be visualized using stacked bar charts.
Measured: max. 30 months (recruitment period)
Assessing parameters of physician treatment satisfaction
Frequencies of distinct satisfaction levels with ivosidenib treatment effectiveness and AE management will be visualized using stacked bar charts.
Measured: max. 32 months (recruitment period plus 8 weeks)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Cholangiocarcinoma, run by iOMEDICO AG at 19 sites in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 22 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 19 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Sina Grebhardt, PhD (+49 761 15 242 31, sina.grebhardt@iomedico.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival (PFS) (time frame: max. 38 months (FPI - LPLV)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06607302, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Oct 2026; AzTrials last refreshed its copy on 8 Nov 2026.
