Could a pill replace surgery for rare liver tumors?

This study tests a drug called baricitinib (a JAK1 inhibitor) to see if it can shrink large inflammatory liver adenomas (a rare, non-cancerous tumor) in 25 people. The goal is to reduce tumor size enough to avoid surgery. Participants will take the drug for a short time, and doctors will monitor tumor changes with MRI scans at 3 and 6 months.
