Liver cancer drug combo put to the test – but trial stops early
NCT ID NCT04777851
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial compared a combination of two drugs (regorafenib and pembrolizumab) with standard locoregional therapies (TACE or TARE) as a first treatment for intermediate-stage liver cancer that has spread beyond certain limits. The study aimed to enroll about 496 people but was terminated early after only 45 participants. Researchers were looking at how long patients lived without their cancer getting worse.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- regorafenib and pembrolizumab
- What this could lead to
- If successful, this combination could offer a new first-line treatment option for people with intermediate-stage liver cancer that is not suitable for surgery.
- What could go wrong
- The trial was terminated early and enrolled only 45 of a planned 496 participants, so results are limited. Both drug combinations carry risks of serious side effects, and it is unclear if the experimental arm is better than existing therapies.
