Clinical and Molecular Response to Vorasidenib in Post-Transplant Patient with IDH2-mutant Intrahepatic Cholangiocarcinoma

An FDA-approved glioma drug achieved a durable response in an aggressive liver cancer, suggesting genetic targeting may work across different cancer types.

A Johns Hopkins case report of vorasidenib (IDH1/2 inhibitor, FDA-approved for IDH-mutant glioma) achieving durable RECIST partial response and ctDNA reduction in an IDH2-mutant intrahepatic cholangiocarcinoma patient post-liver-transplant, a population with very limited options. This ctDNA-monitored case is hypothesis-generating for IDH-targeted therapy expansion in cholangiocarcinoma and immunosuppressed oncology patients.
