NCT ID NCT06301438
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a drug called dalpiciclib in people with a specific type of advanced breast cancer (HR-positive, HER2-negative). The goal is to see how long the drug can keep the cancer from growing and what side effects it causes. About 103 participants will take dalpiciclib as a pill for 21 days on, 7 days off. Researchers will track disease progression and any adverse events.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dalpiciclib (a CDK4/6 inhibitor taken as a pill)
- What this could lead to
- If successful, this study could show that dalpiciclib helps control advanced breast cancer for longer, offering a new treatment option for people with this type of cancer.
- What could go wrong
- This is a real-world study, not a controlled trial, so results may be less reliable. The drug may not work for everyone and can cause side effects like low blood cell counts or fatigue.
