Overactivation of the JAK/STAT pathway is one of the drivers for the pathophysiology of hepatocellular carcinoma (HCC). We propose a Phase Ib study to evaluate the safety and efficacy of itacitinib, a selective JAK1 inhibitor, as a second-line treatment for patients with advanced or metastatic HCC. Twenty-five patients will receive 400 mg itacitinib orally daily, 28-day cycle. Safety will be reviewed prior to each cycle. Tumor response assessed every 2 months until disease progression, death or withdrawal. Tumor biopsies and blood samples will be taken for presence of JAK1 mutations. Activation of JAK/STAT pathway drives HCC development and is associated with immunotherapy resistance. Itacitinib is hypothesized to be safe and effective in HCC patients that have progressed after first-line therapies. Clinical Trial Registration: EudraCT: 2017-004437-81 NCT04358185 (ClinicalTrials.gov).

Abstract

Overactivation of the JAK/STAT pathway is one of the drivers for the pathophysiology of hepatocellular carcinoma (HCC). We propose a Phase Ib study to evaluate the safety and efficacy of itacitinib, a selective JAK1 inhibitor, as a second-line treatment for patients with advanced or metastatic HCC. Twenty-five patients will receive 400 mg itacitinib orally daily, 28-day cycle. Safety will be reviewed prior to each cycle. Tumor response assessed every 2 months until disease progression, death or withdrawal. Tumor biopsies and blood samples will be taken for presence of JAK1 mutations. Activation of JAK/STAT pathway drives HCC development and is associated with immunotherapy resistance. Itacitinib is hypothesized to be safe and effective in HCC patients that have progressed after first-line therapies. Clinical Trial Registration: EudraCT: 2017-004437-81 NCT04358185 (ClinicalTrials.gov).
