Abstract

Background The pivotal RESORCE trial showed that regorafenib was effective as second-line therapy for patients with advanced HCC who progressed on first-line sorafenib. Real-world data are needed to assess clinical outcomes and adverse events in the setting of daily practice. Methods Between April 2017 and August 2017, the Named Patient Program (NPP) was activated to provide controlled, pre-approval access of regorafenib in Korea. This analysis is a multicenter retrospective study of patients who received regorafenib under the NPP. Results A total of 49 patients entered into this NPP, and 40 patients received regorafenib in five Korean institutions. All but one patient received regorafenib as second-line therapy after progression on sorafenib, and 36 (90%) and 34 (85%) patients were classified as Child-Pugh A and BCLC stage C, respectively. The response rate was 10% (n = 4). The median progression-free survival (PFS) was 3.7 months (95% CI, 2.5–4.9 months), and the median overall survival (OS) was not reached. The 1 year OS rate was 54.6%. The time-to-progression (TTP) on prior sorafenib was significantly associated with PFS and OS. The most common grade 3–4 toxicities were hand-foot skin reaction (n = 3, 8%), hypertension (n = 2, 5%), and increased aspartate aminotransferase (n = 2, 5%). Conclusion Regorafenib was well-tolerated and effective in patients with advanced HCC who progressed on first-line sorafenib, with efficacy and safety outcomes consistent with those of the previous RESORCE trial. TTP on first-line sorafenib may predict the efficacy of subsequent regorafenib.
