About this study

Official title: A Pilot Study of Chemoimmunotherapy Combined With Hyperthermia and Spatially-Fractionated Radiotherapy in Advanced Biliary Tract Cancer

This study is being done to see if the investigators can improve the outcome of patients with biliary tract cancer that do not qualify for surgery. This study will compare the effects, good and/or bad, of using a combination of standard of care chemoimmunotherapy, with the addition of radiation and deep hyperthermia. In this study, participants will be receiving standard of care chemoimmunotherapy (gemcitabine, cisplatin, and durvalumab), radiation (spatially fractionated radiation therapy), and deep hyperthermia.

Chemoimmunotherapy Chemoimmunotherapy is when chemotherapy drugs are combined with immunotherapy drugs. Chemotherapy uses different drugs to kill or slow the growth of cancer cells, whereas immunotherapy drugs are used to help the immune system attack cancer cells. For this study, the drugs Gemcitabine, Cisplatin, and Durvalumab will be used. Chemoimmunotherapy will be delivered over 4 cycles for this study and can continue longer if the treating physician decides this is appropriate. Each cycle will last 3 weeks.

Spatially fractionated radiation therapy (SFRT) SFRT is a form of radiation therapy that gives a single large dose of radiation to large tumors or tumors that do not qualify for surgery. This is not a standard type of treatment for people with this diagnosis. For this study, participants will be receiving radiation once on day 1 of the second chemoimmunotherapy cycle.

Deep Hyperthermia (HT) Hyperthermia is used in combination with chemoimmunotherapy and radiation treatment in this study. Hyperthermia has the potential to make both chemotherapy and radiation treatments more effective. For this study, participants will receive HT three times: on the first day of cycles 2, 3, and 4 of chemoimmunotherapy.

What is being measured

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

  1. Number of adverse events assessment by CTCAE v5.0 that are grade 3 or higher and related to HT or SFRT

    Determine the safety of combined deep hyperthermia, spatially-fractionated radiotherapy and chemoimmunotherapy in this patient population

    Safety is defined by < 30% rate of grade 3 or higher non-hematologic adverse events possibly or probably related to deep HT or SFRT from cycle 2-day 1 until 90 days post the final deep HT treatment. A rolling safety evaluation will be performed during patient enrollment and termination of the study will occur if any of the below are met

    • Grade 3+ adverse events in more than 1 of the first 3 or 2 of the first 6 patients possibly or probably related to deep HT or SFRT
    • Grade 4+ adverse event in more than 3 total patients possibly or probably related to deep HT or SFRT
    • Grade 5 adverse event in 1 patient where the event is not clearly attributable to the underlying disease or extraneous causes.

    Measured: 90 days post final treatment of Deep Hyperthermia

  2. Number of participants to receive a minimum of 30 minutes of heating at target temperature (39-43°C) for at least 2 of the planned 3 deep HT treatments

    Estimate the feasibility of administering combined deep hyperthermia, spatially-fractionated radiotherapy and chemoimmunotherapy for subjects with advanced biliary tract cancer not amenable to surgical resection or definitive local therapy.

    Feasibility is defined as the ability of participants to receive a minimum of 30 minutes of heating at target temperature (39-43°C) for at least 2 of the planned 3 deep HT treatments. A single-group design will be used to obtain a two-sided 95% confidence interval for a single proportion (feasibility). The Exact Clopper-Pearson approach will be used to calculate the confidence interval. The sample proportion is assumed to be 0.7. To produce a confidence interval with a width of no more than 0.5, 15 subjects will be needed.

    Measured: 90 days post final treatment

Secondary outcomes (1)
  1. Radiographic Response Rate

    Estimate the radiographic response rate at the 16 week imaging timepoint.

    All participants who undergo at least 1 imaging assessment after beginning study will be eligible for radiographic response estimation per RECIST version 1.1 by local radiology review. Baseline CT or MRI scans will be used to select target and non-target lesions.

    Measured: 16 weeks from start of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Gemcitabine, Cisplatin and Durvalumab in people with Biliary Tract Cancer and Cholangiocarcinoma, run by University of Maryland, Baltimore at 2 sites 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 20 inclusion and 40 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 10 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Contact Jason Molitoris, MD, PhD (410-328-6080, JMolitoris@som.umaryland.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of adverse events assessment by CTCAE v5.0 that are grade 3 or higher and related to HT or SFRT (time frame: 90 days post final treatment of Deep Hyperthermia). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 Dec 2025.
