Study Summary

This early phase I trial studies the side effects of autologous dendritic cells and a vaccine called Prevnar in combination with immune checkpoint inhibition (with bevacizumab and atezolizumab or druvalumab) in treating patients liver cancer that cannot be removed by surgery (unresectable) after undergoing standard high-dose external beam radiotherapy. Autologous dendritic cells are immune cells generated from patients' own white blood cells that are grown in a special lab and trained to stimulate the immune system to destroy tumor cells. A pneumonia vaccine called Prevnar may also help stimulate the immune system. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Immunotherapy with monoclonal antibodies, such as atezolizumab and durvalumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving autologous dendritic cells and Prevnar in combination with immune checkpoint inhibition after radiotherapy may be safe, and tolerable and may stimulate the body's own immune system to fight against the tumor in patients with unresectable liver cancer.

Primary Outcome

A significant toxicity is defined as a dose limiting toxicity that is possibly, probably, or definitely related to dendritic cell (DC) treatment. Toxicities will be assessed using the Cancer Therapy Evaluation Program active version of the Common Terminology Criteria for Adverse Events.
