Safety and efficacy of cabozantinib for patients with advanced hepatocellular carcinoma who advanced to Child–Pugh B liver function at study week 8: a retrospective analysis of the CELESTIAL randomised controlled trial

Abstract

Abstract Background Patients with hepatocellular carcinoma (HCC) and Child–Pugh B liver cirrhosis have poor prognosis and are underrepresented in clinical trials. The CELESTIAL trial, in which cabozantinib improved overall survival (OS) and progression-free survival (PFS) versus placebo in patients with HCC and Child–Pugh A liver cirrhosis at baseline, was evaluated for outcomes in patients who had Child–Pugh B cirrhosis at Week 8. Methods This was a retrospective analysis of adult patients with previously treated advanced HCC. Child–Pugh B status was assessed by the investigator. Patients were randomised 2:1 to cabozantinib (60 mg once daily) or placebo. Results Fifty-one patients receiving cabozantinib and 22 receiving placebo had Child–Pugh B cirrhosis at Week 8. Safety and tolerability of cabozantinib for the Child–Pugh B subgroup were consistent with the overall population. For cabozantinib- versus placebo-treated patients, median OS from randomisation was 8.5 versus 3.8 months (HR 0.32, 95% CI 0.18–0.58), median PFS was 3.7 versus 1.9 months (HR 0.44, 95% CI 0.25–0.76), and best response was stable disease in 57% versus 23% of patients. Conclusions These encouraging results with cabozantinib support the initiation of prospective studies in patients with advanced HCC and Child–Pugh B liver function. Clinical Trial Registration: NCT01908426.
