Safety and effectiveness of sorafenib in Japanese patients with hepatocellular carcinoma in daily medical practice: interim analysis of a prospective postmarketing all-patient surveillance study

View Article: PubMed Central - PubMed

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.

Conclusions: Clinical trial registration number: NCT01411436

Mentions: The time course of onset of DRAE is shown in Fig. 1. DRAE, including hand-foot skin reaction, hypertension, rash, platelet count decreased, increased lipase/amylase, and pyrexia, occurred predominantly in the early stage of treatment [ratio of incidence rates (day 30/day 365), ≥ 0.6], whereas diarrhea, alopecia, hemorrhagic events and ascites occurred over the entire period (ratio < 0.4). liver dysfunction, anorexia, and malaise were intermediate (ratio ≥ 0.4 to < 0.6).Fig. 1
