Eligibility Criteria Checklist

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

Must have

Eastern Cooperative Oncology Group (ECOG) performance status 0-1 (Karnofsky > 70)

Patients must have received at least one standard first-line chemotherapy regimen or have refused chemotherapy

Must not have

Major bleeding in the last 4 weeks

Receipt of any anticancer medication in the 21 days prior to receiving the first dose of study medication or any unresolved toxicity (> grade 1) from previous anticancer therapy, except for stable chronic toxicities not expected to resolve, such as peripheral neurotoxicity. Prior treatment with nitrosoureas (e.g., carmustine or lomustine) require a 6-week washout prior to the first dose of study treatment

Summary

This trial is to find the best dose of radiation and a new immunotherapy drug for bile duct cancer that has spread.

Who is the study for?

This trial is for adults with advanced bile duct cancer who have tried at least one chemotherapy or refused it. They must have two measurable tumors, be in good physical condition, and agree to use birth control. People can't join if they have autoimmune diseases, recent infections requiring antibiotics, major surgery within 4 weeks, received certain treatments recently, untreated brain metastases, are pregnant or breastfeeding.

What is being tested?

The trial tests a combination of hypofractionated radiation therapy (higher doses over a short period) and bintrafusp alfa (an immunotherapy drug). It aims to find the best dose and see how well this combo works against advanced intrahepatic cholangiocarcinoma by helping the immune system attack cancer.

What are the potential side effects?

Possible side effects include typical reactions from radiation like skin irritation and fatigue as well as immune-related effects from bintrafusp alfa such as flu-like symptoms, potential organ inflammation due to an overactive immune response, and infusion reactions.

Experimental Treatment

Group I: Treatment (hypofractionated radiation, bintrafusp alfa)Experimental Treatment3 Interventions

Patients undergo hypofractionated radiation therapy 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 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.
