NCT ID NCT06998407

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

Summary

This study tests a new oral drug called AVZO-023, which blocks a protein (CDK4) that helps cancer cells grow. It is being tested alone or with other drugs in 380 adults with advanced solid tumors, especially a type of breast cancer called HR+/HER2-. The goal is to find a safe dose and see if it can shrink tumors.

What this could mean

Active substance

What this could lead to

If successful, this could lead to a new treatment option for people with advanced breast cancer or other solid tumors that have stopped responding to current therapies.

What could go wrong

This is an early first-in-human study, so safety and effectiveness are not yet known. The drug may cause side effects or fail to shrink tumors, and results may not apply to all patients.
