e16680 Background: REG is approved for the treatment of pts with HCC who previously received SOR, based on results of the phase 3 RESORCE trial. The REFINE study was designed to evaluate the safety and effectiveness of REG in pts with HCC in real-world practice. Methods: This prospective, observational study aims to recruit 1000 pts with unresectable HCC for whom a decision to treat with REG was made by the treating physician prior to enrollment according to the local health authority approved label. The primary endpoint is the incidence of treatment-emergent adverse events (TEAEs) and dose modifications due to TEAEs (NCI-CTCAE v4.03). Secondary endpoints include overall survival (OS) and progression-free survival (investigator assessed). This interim analysis includes the first 500 pts on study for ≥4 months. Results: Of 500 pts enrolled and observed for ≥4 months, 498 received REG and were evaluable (data cut-off: November 11, 2019). Pts were Child-Pugh A 67%, B 11%, C 1%, and missing/not evaluable 21%. Most pts (98%; n = 490) had received prior systemic therapy; 97% (n = 482) had received prior SOR. REG was second line treatment in 81% of pts (n = 403), third line or higher in 17% (n = 87), and first line in 2% (n = 8). Of the 403 pts who received REG second line, 398 (99%) received prior SOR. Among the 482 pts who received SOR in any prior line, the median duration of prior SOR was 4.8 months (interquartile range 2.5–9.6), 45% (n = 216) had a last daily SOR dose of 800 mg, and 8% (n = 40) had a TEAE leading to SOR discontinuation (SOR-intolerant). OS by treatment line is shown in the Table. Among all treated pts, the most frequent TEAEs (any grade) were hand–foot skin reaction (HFSR; 30%), diarrhea (21%), fatigue (16%), and decreased appetite (14%). In SOR-intolerant pts (n = 40), the most frequent TEAEs (any grade) were diarrhea (25%), HFSR (20%), abdominal pain (15%), and decreased appetite (13%). Conclusions: In this interim analysis of REFINE, most pts received REG second line after SOR versus other lines of therapy. Median OS in this subgroup was longer than OS in RESORCE, but the proportion of censored pts was high. The most common TEAEs were similar to those in RESORCE in both the overall cohort and in SOR-intolerant pts. Clinical trial information: NCT03289273 . [Table: see text]
