About
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.
Full description
PRIMARY OBJECTIVE:
I. 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:
I. 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:
I. 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.

- Fertile males must be willing to employ adequate means of contraception during study treatment and for 3 months after the last dose of study drug
- Male subjects must agree to refrain from sperm donation during the study and for 125 days after the last dose of study drugs
- Ability to read and/or understand the details of the study and provide written evidence of informed consent as approved by Institutional Review Board (IRB)/ Scientific Review Committee (SRC)
Exclusion criteria
-
Patients who are pregnant or lactating
-
Patients with uncontrolled intercurrent illness including symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia and myocardial infarction (MI) within 3 months of initiation of therapy
-
Patients with recent bacterial, viral, or fungal infection(s) requiring systemic antibiotic therapy within one month of enrolling
-
Patient has undergone major surgery within 4 weeks prior to day 1 of treatment in this study. Diagnostic or minimally invasive surgery (i.e., done to obtain a biopsy for diagnosis without removal of an organ or to place an abdominal spacer) are acceptable at physician discretion
-
Patient received radiotherapy, surgery, chemotherapy, or an investigational therapy within 2 weeks prior to study entry weeks
-
Patient has serious medical risk factors involving any of the major organ systems such that the investigator considers it unsafe for the patient to receive an experimental research drug
-
Serious psychiatric or medical conditions that could interfere with treatment
-
Major bleeding in the last 4 weeks
-
Receipt of prior immune checkpoint inhibitors (e.g., anti-CTLA-4, anti-programmed cell death receptor 1, anti-programmed cell death ligand 1 [anti-PD-L1], and any other antibody or drug specifically targeting T-cell costimulation)
-
Receiving an immunologically based treatment for any reason, including chronic use of systemic steroid at doses >= 7.5 mg/day prednisone equivalent within 14 days prior to the first dose of study treatment. Use of inhaled or topical steroids or systemic corticosteroids < 7.5 mg is permitted
-
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
-
Untreated central nervous system (CNS) metastases, or CNS metastases that have progressed (e.g., evidence of new or enlarging CNS metastasis or new neurological symptoms attributable to CNS metastases). Subjects with treated and clinically stable CNS metastases and off all corticosteroids for at least 2 weeks are eligible
-
Any active or inactive autoimmune process (e.g. rheumatoid arthritis, moderate or severe psoriasis, multiple sclerosis, inflammatory bowel disease) or who are receiving systemic therapy for an autoimmune or inflammatory disease
- Note: Exceptions include subjects with vitiligo, hypothyroidism stable on hormone replacement, controlled asthma, type I diabetes, Graves' disease, or Hashimoto's disease, or with medical monitor approval
