Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Age >= 18 years with body weight > 30 kg

Histologically or cytologically confirmed, locally advanced intrahepatic cholangiocarcinoma that is not amenable to resection, transplantation, or thermal ablation. Oligometastatic intrahepatic cholangiocarcinoma is also eligible. Specifically, such patients must have EITHER =< 3 malignant extrahepatic lymph nodes (short axis diameter >= 3cm) OR metastatic lesions in one organ other than liver (if only single lesion is present diameter MUST be < 3cm, if up to 3 lesions in one organ each lesion MUST be =< 1cm)

Must not have

History of another primary malignancy except for:

Surgery =< 28 days prior to registration

Timeline

Screening 3 weeks

Treatment Varies

Follow Up up to 24 months

Summary

This trial tests if combining Y90 radioembolization with immunotherapy can help treat advanced, unresectable intrahepatic cholangiocarcinoma, a rare and aggressive cancer with few curative options.

Who is the study for?

This trial is for adults over 18 with locally advanced, unresectable intrahepatic cholangiocarcinoma who can't have curative therapy. They should be in good physical condition (ECOG PS 0 or 1), not pregnant, and without severe concurrent diseases or a history of multiple treatments for this cancer.

What is being tested?

The trial tests Y90 radioembolization combined with two monoclonal antibodies, tremelimumab and durvalumab. It aims to see if this combination is safe and effective at killing more tumor cells in patients who cannot undergo surgery.

What are the potential side effects?

Potential side effects include typical reactions to immunotherapy like fatigue, skin reactions, inflammation of organs as well as those related to radiation such as localized pain or damage to surrounding tissues.

Trial Design

2Treatment groups

Experimental Treatment

Group I: Cohort II: (Y90, tremelimumab on day 14, cycle 1, durvalumab )Experimental Treatment9 Interventions

Patients receive transarterial Y90 radioembolization on day 1 of cycle 1 and receive tremelimumab IV over 1 hour on day 14 of cycle 1 and durvalumab IV over 1 hour on day 14 of each cycle. Cycles repeat every 42 days for cycle 1 and then every 28 days for cycles 2-24 in the absence of disease progression or unacceptable toxicity. Patients also undergo mapping angiography during screening, as well as CT and MRI or PET/CT during screening and on study. Patients also undergo blood sample collection throughout the trial and may undergo tumor biopsy during screening and on study.
