Summary

This study looks at how gut bacteria affect diarrhea and other stomach issues in people with HR+/HER2- breast cancer taking the drug abemaciclib. In the first part, researchers will collect stool samples to track bacteria changes. In the second part, a small group will try eating chia seeds daily to see if it helps. Only 20 people will take part, and the main goal is to see if collecting samples is practical.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Chia seeds (fiber supplement)
What this could lead to: If successful, this could point toward simple dietary changes to reduce diarrhea and other gut side effects from breast cancer treatment.
What could go wrong: This is a very small pilot study (20 people) that is not yet recruiting. It mainly tests whether collecting stool samples is feasible, not whether the diet works. Results may not apply to other patients.
