Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Each enrolling center will be responsible for identifying patients eligible for the study. Information will be collected for each patient regarding: * Patient and treatment characteristics: age, date of diagnosis, and data relating to any treatments received. * Biological characteristics of the primary disease: histotype, grade, hormone receptor and HER2 expression, and cytoproliferative activity. The data collected reflect those normally collected in clinical practice for patients diagnosed with breast cancer. No additional specific visits or assessments are required.

Who may be able to join

  • Age 18 years or older
  • Patients carrying a pathogenic or likely pathogenic germline variant in BRCA1 or BRCA2 with a histologically confirmed diagnosis of HR+/HER2-negative breast cancer
  • Patients with available hospital and/or outpatient medical records for clinical data collection
  • Presence of available formally fixed paraffin-embedded (FFPE) breast tumor tissue (primary or metastatic site)

Who cannot join

  • None

About this study

This study is an observational study being carried out in several hospitals. No extra tests or procedures are required beyond those already part of normal medical care.

The study is sponsored by the University of Modena and Reggio Emilia and aims to include about 100 patients.

The main goal of the study is to better understand the different biological types of breast cancer in patients who have hormone receptor-positive (HR-positive), HER2-negative breast cancer related to BRCA gene mutations. In particular, the study will explore whether these cancers tend to belong to molecular types that may respond less to endocrine or CDK4/6 inhibitor therapy.

The study also compares cancers linked to BRCA1 and BRCA2 mutations and investigates whether the different biological types are associated with differences in disease outcomes and response to treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Distribution of intrinsic subtypes in BRCA1 and BRCA2-associated HR+/HER2-negative tumors

    To evaluate the differences in intrinsic subtype distribution between BRCA1 and BRCA2-associated HR+/HER2-negative tumors.

    Measured: through study completion

  2. Overall survival depending on intrinsic subtype

    To explore the prognostic role of different intrinsic subtypes in terms of overall survival (OS) in HR+/HER2-negative BRCA-associated breast cancer

    Measured: through study completion

Secondary outcomes (2)

  1. Benefit from CDK4/6 inhibitors depending on molecular subtype

    Evaluating sensitivity to CDK4/6 inhibitors and PARP inhibitors by molecular subtype in HR+/HER2-negative BRCA-related tumors.

    Measured: through study completion

  2. Molecular features of BRCA1-related and BRCA2-related breast cancers

    To evaluate, through a multigene panel, the different molecular expression of HR+/HER2-negative BRCA1-related and BRCA2-related breast cancers.

    Measured: through study completion

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Angela Toss at 6 sites in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 1 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Distribution of intrinsic subtypes in BRCA1 and BRCA2-associated HR+/HER2-negative tumors (time frame: through study completion). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07617025, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2026.
