Liver Cancer Patients Needed

National Cancer Institute researchers are testing a new treatment in people with liver cancer (hepatocellular carcinoma). The treatment uses nivolumab (immune therapy) given in combination with tadalafil and vancomycin (an antibiotic that changes the gut bacteria) to see if the tumors shrink. Participants do not pay for tests, treatments or procedures. Travel may be reimbursed.
