Summary

This trial tests a multicomponent adherence intervention designed to help patients with metastatic breast cancer and cardiovascular disease take their endocrine therapy, CDK4/6 inhibitors, and heart medications as prescribed. The study enrolls 35 adults who have reported some nonadherence. Researchers will measure changes in medication adherence and quality of life, and explore how social factors affect medication use.

What this could mean

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

Active substance
a multicomponent adherence intervention (behavioral support to reduce barriers to medication use)
What this could lead to
If effective, this approach could improve medication adherence and health outcomes for patients managing both metastatic breast cancer and cardiovascular disease.
What could go wrong
This is a small, early-stage trial with only 35 participants, so results may not apply broadly. The intervention relies on self-report and pharmacy data, which may not capture full adherence.
