The RESORCE trial evaluated the efficacy and safety of STIVARGA® (regorafenib)1,2
REgorafenib after SORafenib in patients with hepatoCEllular carcinoma (RESORCE) was an international, multicenter, randomized (2:1), double-blind, placebo-controlled phase 3 trial that evaluated the efficacy and safety of STIVARGA in HCC patients with progression following sorafenib (N=573).
- Patients who permanently discontinued sorafenib due to toxicity or who were unable to tolerate sorafenib doses of 400 mg once daily were ineligible for the trial
Primary endpoint1,2:
- Overall survival (OS), analyzed by intention to treat
Secondary endpoints1,2:
- Progression-free survival (PFS), time to progression, overall response rate (ORR; patients with complete response [CR] or partial response [PR]), disease control rate (DCR; patients with CR, PR, or stable disease [SD] for ≥6 weeks)
- Analyzed by intention to treat; assessed using modified Response Evaluation Criteria In Solid Tumors (mRECIST) and RECIST 1.1
Tertiary endpoint1,2:
- Duration of response
Patients in the RESORCE trial had good performance status and preserved liver function1,2
Baseline patient characteristics were similar between each arm1,2

STIVARGA more than doubled PFS vs placebo1,2
3.1-month median PFS achieved with STIVARGA vs 1.5 months with placebo
Reduction in risk of progression or death with STIVARGA was consistent when assessed by RECIST 1.1
- 3.4-month (95% CI, 2.9-4.2) median PFS achieved with STIVARGA vs 1.5 months (95% CI, 1.4-1.5 with placebo (HR: 0.43; 95% CI, 0.35-0.52) (RECIST 1.1)
- Number of progressions or deaths: 288 of 379 (76%) in the STIVARGA arm; 184 of 194 (95%) in the placebo arm
