Combination of Abemaciclib and Endocrine Therapy in Hormone Receptor Positive HER2 Negative Locally Advanced or Metastatic Breast Cancer With Focus on Digital Side Effect Management

Is NCT05362760 recruiting? Yes, currently enrolling (May 2026). This Phase 4 trial studies multiple treatments including Abemaciclib + Aromatase Inhibitor and Abemaciclib + Fulvestrant for hormone receptor-positive metastatic breast cancer.

Phase 4RecruitingProf. Wolfgang JanniNCT05362760Data as of May 2026

Treatment: Abemaciclib + Aromatase Inhibitor · Abemaciclib + FulvestrantThe MINERVA Trial aims to evaluate safety, efficacy and quality of life (QoL) for the combination of Abemaciclib with an Aromatase Inhibitor or Fulvestrant in pre- and postmenopausal patients with metastatic hormone receptor positive HER2 negative breast cancer in the first line setting. Side effect monitoring and patient reported outcomes will be captured using the web- and app-based CANKADO digital health application. Via this user-friendly tool the patients can document their therapy side effects (e.g. diarrhea) and outcomes on a day-to-day basis. The capturing of side effects using the digital health application will be done additionally to the regular AE documentation. Furthermore, translational research objectives of this trial include the investigation of biomarkers (ct-DNA, germline DNA) to evaluate whether they can give insights into the reasons for response, intrinsic or acquired resistance to the combined endocrine

Required: PR (PGR) overexpression (IHC positive as per ASCO/CAP guidelines)

a breast cancer must express, by immunohistochemistry (IHC), at least one of the hormone receptors (estrogen receptor [ER], progesterone receptor [PgR]) as defined in the relevant American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) Guidelines

Required: HER2 (ERBB2) wild-type (no overexpression by IHC or ISH as per ASCO/CAP guidelines)
