About this study

Official title: "Window of Opportunity" Phase I Trial of Focal Radiotherapy and Bintrafusp Alfa In Patients With Advanced Intrahepatic Cholangiocarcinoma

This phase I trial is to find out the best dose, possible benefits, and/or side effects of hypofractionated radiation therapy and bintrafusp alfa in treating patients with bile duct cancer that has spread to other places in the body (advanced intrahepatic cholangiocarcinoma). Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Immunotherapy with bintrafusp alfa, a bifunctional fusion protein composed of the monoclonal antibody avelumab and TGF-beta, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The combination of hypofractionated radiation therapy and bintrafusp alfa may help to control intrahepatic cholangiocarcinoma.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To examine the safety of bintrafusp alfa in combination with hypofractionated radiation therapy for patients with advanced intrahepatic cholangiocarcinoma and recommend a phase II radiation dose.

SECONDARY OBJECTIVES:

  1. To estimate objective response rate, local progression free survival, progression free survival, overall survival with the study regimen.

II. To correlate expression of TGF-beta related pathways with clinical outcomes.

III. To examine intratumoral pharmacodynamic changes in the immune microenvironment using paired biopsies before and after therapy with the study agents.

EXPLORATORY OBJECTIVE:

  1. To correlate immune biomarkers from pre- and post-treatment tissue, blood, and stool with clinical study endpoints.

OUTLINE: This is a dose de-escalation study of radiation therapy followed by a dose-expansion study.

Patients undergo hypofractionated radiation therapy once daily (QD) on weekdays (Monday-Friday) for 15 fractions in the absence of disease progression or unacceptable toxicity. Beginning 1 week after completion of radiation therapy, patients receive bintrafusp alfa intravenously (IV) over 1 hour on day 1. Cycles repeat every 14 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 12 weeks for up to 2 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of adverse events (AEs)

    AEs will be graded according to Common Terminology Criteria for Adverse Events version 5.0. AEs will be summarized by patient incidence rates, therefore, in any tabulation, a patient contributes only once to the count for a given AE preferred term. The number and percentage of patients with any treatment-emergent AE will be summarized for all study patients combined.

    Measured: Up to 60 days

Secondary outcomes (4)

  1. Objective response rate

    Will estimate the objective response rate by Response Evaluation Criteria in Solid Tumors 1.1 criteria separately with appropriate 95% confidence intervals.

    Measured: Up to 2 years post-treatment

  2. Local progression free survival (LPFS)

    Will estimate the LPFS distributions using the Kaplan-Meier product limit method and report summary measures such as the median value and probabilities at selected times with appropriate 95% confidence intervals.

    Measured: Up to 12 months post-treatment

  3. Progression free survival (PFS)

    Will estimate the PFS distributions using the Kaplan-Meier product limit method and report summary measures such as the median value and probabilities at selected times with appropriate 95% confidence intervals.

    Measured: Up to 12 months post-treatment

  4. Overall survival (OS)

    Will estimate the OS distributions using the Kaplan-Meier product limit method and report summary measures such as the median value and probabilities at selected times with appropriate 95% confidence intervals.

    Measured: Up to 12 months post-treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Bintrafusp Alfa, Biopsy and Hypofractionated Radiation Therapy in people with Locally Advanced Intrahepatic Cholangiocarcinoma and Metastatic Intrahepatic Cholangiocarcinoma, run by M.D. Anderson Cancer Center at 1 site in United States.

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 17 inclusion and 14 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: under way, not looking for participants, as of the sponsor's last update on 14 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of adverse events (AEs) (time frame: Up to 60 days). 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 NCT04708067.

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 14 Sep 2026.
