Inclusion and exclusion criteria

Inclusion Criteria

Cohort 1:
• BC patients, male and female, 18 years old and older, pre or post menopausal,
with HR+ (ER and/or PR positive), Her-2 negative (confirmed centrally)
locally advanced irresectable and/or metastatic disease
• Confirmation of HR and Her-2 status may be performed in the primary tumor
or in the metastatic lesion (patients with discordant results may be included)
• Patients must be candidates to CDK4/6i therapy in combination with endocrine
therapy in the first line setting (with or without ovarian suppression)
• Patients may have received one previous line of chemotherapy in the metastatic
setting, but no endocrine therapy in the metastatic setting is allowed
• Patients may have received chemotherapy in the neo/adjuvant setting
• Patients may have received endocrine therapy (with or without ovarian
suppression) in the neo/adjuvant setting
• Patients may have received a CDK4/6i in the adjuvant setting, provided they
are still candidates for CDK4/6i therapy in the metastatic setting
• Patients must be able to undergo a liquid biopsy procedure before starting their
first line treatment
• All patients must fill and sign an informed consent form.
Cohort 2:
• BC patients, male and felame, 18 years old and older, pre or post menopausal,
with HR+ (ER and/or PR positive), Her-2 negative (confirmed centrally)
locally advanced irresectable and/or metastatic disease who have progressed on
a CDK4/6i in combination with endocrine therapy (with or without ovarian
suppression) in the first or second line setting
• All other non-conflicting inclusion criteria for cohort 1 apply.

Exclusion Criteria

Patients with HR+ (ER and/or PR positive) and Her-2 negative disease NOT
confirmed centrally
• Patients with NO radiologic and/or pathologic confirmed locally irresectable
and/or metastatic breast cancer
• Patients who are NOT candidates for further systemic treatment after diagnosis
of metastatic disease or disease progression
• Patients who have already started a CDK4/6i in combination with endocrine
therapy (with or without ovarian suppression) for metastatic disease in the first
line setting (for cohort 1); and patients who have already started a new line of
treatment for metastatic disease after disease progression on a CDK4/6i in
combination with endocrine therapy (with or without ovarian suppression)(for
cohort 2)
• Patients who are NOT able to undergo a liquid biopsy procedure
• Patients who are NOT able to provide informed consent.
