Gastrointestinal Cancer clinical trials at University of California Health

This phase II trial studies how well radiation therapy works for the treatment of gastrointestinal cancer that are spreading to other places in the body (metastatic). Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. This trial is being done to determine if giving radiation therapy to patients who are being treated with immunotherapy and whose cancers are progressing (getting worse) can slow or stop the growth of their cancers. It may also help researchers determine if giving radiation therapy to one tumor can stimulate the immune system to attack other tumors in the body that are not targeted by the radiation therapy.

This is an open-label, prospective phase two basket trial assessing the efficacy of ulixertinib in combination with hydroxychloroquine in patients with advanced gastrointestinal malignancies. All patients enrolled must have a mitogen-activated protein kinase (MAPK) activating mutation to be deemed eligible for trial participation. Each disease-based basket will open to enrollment in two-stages. The opening of stage two will be dependent on the observed responses in the patients enrolled in the first stage.
