What this trial studies

This is a retrospective observational analysis of treatment records to measure persistence with abemaciclib among women with high‑risk HR+/HER2‑ early breast cancer. The study will include patients aged 18 or older who started abemaciclib between January 1, 2023 and June 30, 2025 and were treated according to the product labeling. Patients with distant metastases, male patients, or those with documented contraindications to abemaciclib are excluded. Data will be drawn from the Uniklinikum Erlangen site and analyzed to determine the proportion of patients still on therapy six months after initiation and to describe reasons for discontinuation where available.

Who should consider this trial

Good fit: Women aged 18 or older with confirmed HR+/HER2‑ early breast cancer who were prescribed abemaciclib between January 1, 2023 and June 30, 2025 and have no distant metastases or contraindications are the ideal candidates for inclusion.

Not a fit: Male patients, people with locally advanced or metastatic breast cancer, and patients who never started abemaciclib would not be included and would not directly benefit from the study findings.

Why it matters

Potential benefit: If the study identifies early discontinuation patterns, clinicians and care teams could target support to improve treatment persistence and potentially improve outcomes.

How similar studies have performed: Real‑world adherence and persistence studies of CDK4/6 inhibitors have reported variable persistence, but retrospective data specifically focused on abemaciclib in high‑risk early HR+ disease remain limited.
