Abstract:

Background: We aimed to compare the efficacy and tolerability of SECOX regimen with sorafenib alone as first-line treatment of advanced hepatocellular cancer (HCC) in a multicenter, open-label and randomized setting. Methods: Patients not suitable for surgery or various loco-regional therapies and no prior systemic therapy for advanced HCC were recruited in 3 centres. Eligible patients were randomly assigned to receive either SECOX (sorafenib 400 mg BD continuously, oxaliplatin 85 mg/m2 on D1, and capecitabine 1700 mg/m2 on D1-7 q2w) or sorafenib alone continuously in 1:1 ratio. Primary endpoint was time-to-progression (TTP). Secondary endpoints were tolerability, overall tumor response rate, overall survival (OS) and progression-free survival (PFS). Results: Forty-six patients were randomized and treated, of whom 22 were in the SECOX arm. Median age was 64 years and majority of the patients were male (72%). 40 patients (87%) were hepatitis B carrier, and 42 patients (91%) had Child-Pugh A liver function. Thirty patients (65%) had received prior non-systemic treatment for HCC. Median duration of follow-up was 7.8 months (mos) (range 0.3-25.8). At the time of analysis,one patient in the SECOX arm is still receiving treatment. Median TTP was 3.2 mos (95% CI 1.7-5.8) for SECOX vs 2.8 mos (95% CI 1.8-4.0) for sorafenib. The hazard ratio (HR) for TTP was 0.91 (95% CI 0.5-1.7; p = 0.77; predetermined futility boundary HR ≥ 0.86). Median OS was 7.1 mos (95% CI 3.0-15.3) for SECOX vs 12.5 mos (95% CI 7.2-15.4) for sorafenib (p = 0.29). Median PFS was 3.1 mos (95% CI 1.6-5.8) for SECOX vs 2.7 mos (95% CI 1.8-4.0) for sorafenib. 2 patients (9%) and no patients achieved partial response in the SECOX and sorafenib arms, respectively. The clinical benefit rate (CR+PR+SD) was 36% for the SECOX arm and 21% for the sorafenib arm (p = 0.50). Incidence of treatment-related adverse events (trAEs) was common in both SECOX and sorafenib arms (64% and 71% respectively, p = 0.75). The most common grade 3-4 trAE was ALP increase (14%) for SECOX and hand-foot skin reaction (25%) for sorafenib. Conclusions: The addition of capecitabine and oxaliplatin to sorafenib did not result in significant improvement in TTP. Clinical trial information: NCT02716766
