First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase II trial tests the drug trametinib in 35 patients with advanced cancers that have certain BRAF mutations or fusions. The goal is to see if trametinib can shrink or stop cancer growth by blocking proteins that help cancer cells grow. The study focuses on patients whose cancers have not responded to other treatments.

What this could lead to

If successful, this could provide a targeted treatment option for patients with certain BRAF mutations or fusions that are not covered by existing therapies.

This is a small, early-phase trial with only 35 participants, so results may not apply broadly. The drug may not shrink tumors or could cause side effects like heart rhythm issues.
