A woman is considered of childbearing potential, i.e. fertile, following menarche and until becoming post- menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy.

Such methods include: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, or transdermal); progestogen- only hormonal contraception associated with inhibition of ovulation (oral, injectable, or implantable); intrauterine device; intrauterine hormone-releasing system; bilateral tubal occlusion/ligation; vasectomized partner; or sexual abstinence. Male patients with partners of childbearing potential must use barrier contraception. All study patients should practice effective contraception, as described above, starting from the signing of informed consent until 7 months after the last dose of study medication or investigational medicinal product. 14. Patient must provide signed informed consent per a consent document that has been approved by an institutional review board or independent ethics committee (IRB/IEC) prior to initiation of any study-related tests or procedures that are not part of standard-of-care for the patient's disease. 15. Patients must be willing and able to comply with study procedures. 1. No evidence of brain metastases 2. Untreated brain metastases not needing immediate local therapy. For patients with untreated CNS lesions \> 2.0 cm on screening contrast brain MRI, discussion with and approval from the medical monitor is required prior to enrollment, 3. Previously treated brain metastases a. Brain metastases previously treated with local therapy may either be stable since treatment or may have progressed since prior local CNS therapy, provided that there is no clinical indication for immediate re-treatment with local therapy in the opinion of the site investigator, b.

Have received treatment with any systemic anti-cancer therapy (including hormonal therapy), non-CNS radiation, or experimental agent ≤ 3 weeks of first dose of study treatment or are currently participating in another interventional clinical trial. An exception for the washout of hormonal therapies is gonadotropin releasing hormone (GnRH) agonists used for ovarian suppression in premenopausal women, which are permitted concomitant medications. 5. Have any toxicity related to prior cancer therapies that has not resolved to ≤ Grade 1, with the following exceptions: 1. alopecia and neuropathy, which must have resolved to ≤ Grade 2; and 2. congestive heart failure (CHF), which must have been ≤ Grade 1 in severity at the time of occurrence, and must have resolved completely. 3. anemia, which must have resolved to ≤ Grade 2 6.

Have any other medical, social, or psychosocial factors that, in the opinion of the investigator, could impact safety or compliance with study procedures. 16. Have evidence within 2 years of the start of study treatment of another malignancy that required systemic treatment. 1. Any untreated brain lesions \> 2.0 cm in size, unless discussed with medical monitor and approval for enrollment is given. 2. Ongoing use of systemic corticosteroids for control of symptoms of brain metastases at a total daily dose of \> 2 mg of dexamethasone (or equivalent). However, patients on a chronic stable may be eligible with discussion and approval by the medical monitor. 3.
