NCT ID NCT06390839

First seen Oct 31, 2025 · Last updated Jun 23, 2026 · Updated 30 times

Summary

This phase II trial is testing the drug palbociclib in 43 patients with advanced cancers that have extra copies of the CDK4 or CDK6 genes. Palbociclib works by blocking signals that tell cancer cells to multiply. The study aims to see if the drug can shrink tumors or slow their growth in these genetically selected cancers.

Active substance

palbociclib (a kinase inhibitor pill that blocks cancer cell growth signals)

What this could lead to

If successful, this could provide a new treatment option for patients with advanced cancers that have specific CDK4 or CDK6 gene changes.

What could go wrong

This is a small, early-phase trial (43 patients) with no control group, so results may not apply broadly. The drug may not shrink tumors or improve survival for many participants.
