This single-arm, phase II study included treatment-naive patients with advanced HCC (NCT04044313).
Patients initiated Lenvima 3-7 days prior to initial HAIC and then continued to receive Lenvima but with Toripalimab and HAIC with chemotherapy which was the FOLFOX regimen.
The trial enrolled 36 patients.

Serious side effects occurred in 72.2% of patients, the most common being thrombocytopenia (13.9%), elevated aspartate aminotransferase (AST; 13.9%) and hypertension (11.1%).
Moreover, the most common any side effects were hypoalbuminemia (69.4%), elevated AST (66.7%), and elevated alanine aminotransferase (ALT; 58.3%).
However, all side effects were expected and managed, with no treatment-related deaths occurring on the study.
Conclusion
