Researchers want to study if a combination of drugs helps people with these cancers. The drugs are nivolumab, tadalafil, and vancomycin. Objective: To investigate if nivolumab given with tadalafil and vancomycin causes liver cancer to shrink. Eligibility: Adults ages 18 years and older with hepatocellular carcinoma or metastases to the liver from colorectal or pancreatic cancer for which standard treatment has not worked Design: Participants will be screened with: Medical and cancer history Review of symptoms and ability to perform normal activities Physical exam Heart test. Some participants may meet with a cardiologist and/or have another heart test. Scan of the chest, abdomen, and pelvis Blood and urine tests Tumor sample review. This can be from a previous procedure.
