ABSTRACT
Background: Sorafenib was approved for treatment of unresectable hepatocellular carcinoma (HCC) in Japan in 2009. A prospective postmarketing all-patient surveillance (PMS) study was requested by Japanese authorities to confirm safety and effectiveness of sorafenib in Japanese HCC population. Methods: Patients with unresectable HCC treated with sorafenib were followed up for 12 months. Data on patient demographic characteristics, treatment status, clinical outcome, and adverse events (AEs) were collected. Results: This interim analysis included 1109 and 1065 patients evaluable for safety and effectiveness, respectively. Most patients (83.4 %) received the recommended initial dose of 400 mg twice daily. After a follow-up of 12-months, 89.8 % had discontinued treatment, most because of AEs (44.5 %) or progression (33.8 %). The most common drug-related adverse events (DRAE) were hand-foot skin reaction (51.4 %), liver dysfunction (26.4 %), diarrhea (25.1 %), and hypertension (21.6 %). The median overall survival (OS) was 348 days [95 % confidence interval (CI) 299–389 days], and the median duration of treatment was 87 days (95 % CI 78–98 days). Multivariate analyses identified baseline prognostic factors for longer OS, including female sex, low Child-Pugh score, Eastern Cooperative Oncology Group performance status 0, tumor stage I/II/III, low aspartate aminotransferase level, high hemoglobin level, hepatitis C and history of surgical resection. Conclusions: In general, the safety and effectiveness findings in this PMS were consistent with findings from previous clinical studies. Sorafenib was well tolerated and clinically useful for Japanese patients.

Fig2: Kaplan–Meier analyses of OS (effectiveness-analysis set): a OS of overall population of patients; b OS by baseline Child-Pugh class (CP A and CP B); c OS by baseline Child-Pugh score (A5, A6, B7, and ≥B8); d OS by baseline ECOG PS (PS 0, 1, and ≥2); and e OS by etiology. OS overall survival, CP Child-Pugh, ECOG PS Eastern Cooperative Oncology Group performance status, NASH nonalcoholic steatohepatitis Mentions: The ORR was 5.4 %, and DCR was 39.3 % (Table S1), and the median OS was 348 days (95 % CI 299–389 days). The median OS decreased from Child-Pugh A5 [452 (95 % CI 404–519) days], A6 [258 (210–302) days], B7 [159 (101–260) days], to ≥ B8 [91 (41–162) days; Fig. 2].Fig. 2 |
