Regorafenib,
does it really help with Prolonged overall survival in hepatocellular carcinoma that progressed after sorafenib?

30-Second Summary

Evidence Grade A · 90 · Safety unknown
Regorafenib prolongs overall survival in hepatocellular carcinoma that progressed after sorafenib
What the
research shows
Regorafenib is rated A because it prolonged overall survival in hepatocellular carcinoma that progressed during sorafenib treatment. In the 573-participant phase 3 RESORCE trial, it reduced the risk of death by 37% versus placebo (HR 0.63), with median overall survival of 10.6 versus 7.8 months. Progression-free survival also improved from 1.5 to 3.1 months. Hand-foot skin reaction, hypertension, diarrhea, and hepatotoxicity require separate management.
What the
ads claim
Marketing may broaden the claim to all second-line liver cancer, while the evidence directly concerns sorafenib-tolerant patients with preserved liver function whose disease progressed.

Useful facts when choosing a product

  • Regorafenib is an oral multitarget kinase inhibitor; RESORCE used 160 mg once daily for the first 21 days of each 28-day cycle.
  • Food instructions and dose modification must follow the product label, and toxicity often requires reduction or interruption.
  • Hand-foot skin reaction, hypertension, fatigue, diarrhea, and reduced appetite are common, and severe liver injury can occur.
  • Liver tests and blood pressure require monitoring, with assessment of bleeding, wound-healing, and interaction risks.

01

What the research actually shows

Bruix and colleagues conducted RESORCE as an international multicenter double-blind phase 3 trial, comparing 379 regorafenib recipients with 194 placebo recipients. Overall and progression-free survival improved consistently, and objective response was 11% versus 4%. Bayer funded the single pivotal trial, but randomization, placebo control, and the mortality endpoint give it high weight.

02

Why this is classified as A (90)

RESORCE demonstrated overall survival HR 0.63 and a 2.8-month median difference, with consistent progression-free survival HR 0.46. This ingredient-specific large placebo-controlled mortality endpoint supports A with 90 points.

Counterpoint. The median survival difference was measured in months and toxicity is substantial; prior sorafenib tolerance, liver function, and performance status determine applicability.

Rejudgment record. New verdict — Ingredient-specific direct evidence from the randomized phase 3 RESORCE comparison of regorafenib versus placebo, with significant gains in overall and progression-free survival

Sub-claim grades by effect

This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.

Effect (sub-claim)GradeBasis
Prolonged overall survivalA10.6 versus 7.8 months, HR 0.63.
Prolonged progression-free survivalA3.1 versus 1.5 months, HR 0.46.

Cross-check — Codex and Claude

This verdict was drafted by Codex through literature review and source-existence checks, cross-checked through blind grading and adversarial audit, and settled by reapplying the methodology boundary rules. Cases with split grades were resolved through rejudgment.
