Think one step ahead for your HCC patients previously treated with sorafenib

Man is walking up three steps in a flower-filled meadow. The last step has a STIVARGA (regorafenib) logo on it.

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

RESORCE trial design1,2

Graphic outlining STIVARGA (regorafenib) RESORCE trial design. Patients were randomly (2:1 ratio) treated with Stivarga or Placebo. All patients received best supportive care and were treated until disease progression or unacceptable toxicity.

Primary endpoint1:

  • 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 endpoint2:

  • 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

Reduction in risk of progression or death with STIVARGA was consistent when assessed by RECIST 1.12

  • 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
