Multiple Adjunct Therapies to Improve Immunotherapy Treatment in Patients With Locally Advanced or Metastatic Melanoma or Advanced Hepatocellular Cancer

This clinical trial tests the effect of multiple therapies (propranolol, desloratadine, and magnesium and vitamin D supplements) added to primary standard of care immunotherapy (adjunct), as well as adjusting the timing of standard immunotherapy to a morning infusion, in treating patients with melanoma that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started to other places in the body (metastatic) or hepatocellular cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Propranolol is a medication used for high blood pressure. Desloratadine is a type of drug that blocks the action of histamines, which can cause fever, itching, sneezing, a runny nose, and watery eyes. Immunotherapy has been approved for multiple kinds of advanced cancers, including melanoma, kidney cancer, non-small cell lung cancer and hepatocellular (liver) cancer. Research suggests that giving propranolol and desloratadine, along with ensuring adequate levels of magnesium and vitamin D, as well as administering immunotherapy infusions in the morning may shrink or stop the spread of advanced cancers better than immunotherapy alone.
