- •- For perimenopausal women to be considered of non-childbearing potential, FSH levels must be higher than 40 mIU/ml.
- •3. Patient must have ER positive, HER-2 negative tumor status as confirmed by local laboratory testing either from a fresh biopsy or from an archival tissue obtained no more than 2 years prior to signing of the
- •informed consent form. For Phase 1b, the presence of brain metastases is allowed but not required for eligibility, in this case, at least 1 measurable lesion outside the brain is required.
- •- ER and HER-2 testing must be performed in the following manner:
- •o Documentation of ER positive tumor with equal or higher than 1% staining by immunohistochemistry (IHC) as defined in the 2010 or 2020 American Society for Clinical Oncology (ASCO) recommendations for ER testing (Hammond et al, 2010; Allison et al, 2020), with or without progesterone receptor (PGR) positivity
- •o HER-2 negative tumor with an IHC result of 0 or 1+ for cellular membrane protein expression or an in situ hybridization negative result as defined in the 2013 or 2018 ASCO recommendations for HER-2 testing (Wolff et al, 2013; Wolff et al, 2018)

- •- Any of the following qualifies brain metastases as active:
- •a) Newly diagnosed brain metastasis in patients who never received prior central nervous system (CNS)-directed therapy
- •b) Newly diagnosed brain metastasis outside any area that was previously subjected to CNS-directed therapy
- •c) Brain metastases that are progressing in an area that has previously been subjected to CNS-directed therapy.
- •- For lesions, including brain metastases, to qualify as measurable, and possibly be selected as target lesions, per RECIST version 1.1, the longest diameter must be equal or higher than 10 mm by CT or MRI).
- •5. Patients must be off corticosteroids or receiving a stable or decreasing corticosteroid dose at the time of starting trial therapy. The dose must be equal or less than 2.0 mg/day of dexamethasone or equivalent.
- •6. Any neurological symptoms of brain metastases must be stable for at least 4 weeks before starting trial therapy.
