Phase II clinical trial of cabozantinib for the treatment of recurrent hepatocellular carcinoma after liver transplantation.

Liver cancer is the sixth most diagnosed cancer worldwide with few available curative treatments. Liver transplantation (LT) is considered as one of the treatments for liver cancer especially in earlier stages of cancer. However, after LT, cancer develops again in 15­20% of the patients who undergo transplant for liver cancer. Compared with liver cancer in the nontransplant population, recurrent cancer grows faster and spreads in the body very quickly. Therefore, unfortunately, to date there are limited treatment options for these patients without significant effect on their survival. In this study, we aim to evaluate the effect of a new medication called cabozantinib on patients who develop recurrent liver cancer after their LT. Cabozantinib has been already tested in patients with liver cancer and was shown to be effective and safe in nontransplant patients. However, this is the first study to evaluate the effect of cabozantinib in liver transplant recipients with recurrent liver cancer. Clinical Trial Registration: NCT04204850 (ClinicalTrials.gov).
