First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study is testing whether taking endocrine therapy in the morning or evening makes a difference for people with metastatic breast or prostate cancer. Fifty participants will be randomly assigned to take their medication either within an hour of waking or within an hour of bedtime. The main goal is to see if a larger trial is possible, while also looking at quality of life, side effects, and how well the treatment works.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
endocrine therapy (CDK4/6 inhibitor or androgen receptor pathway inhibitor)
What this could lead to
If successful, this could show that simply changing the time of day you take your medication improves quality of life and treatment tolerability.
What could go wrong
This is a small pilot study with only 50 participants, so results may not apply broadly. The main goal is to see if a larger trial is possible, not to prove effectiveness.
