- Cancer must be HER2-positive, according to ASCO-CAP guidelines. Any ER and PR status is allowed.
- Participants must have documented disease progression while receiving dual anti-HER2 targeted therapy for metastatic breast cancer, as per investigator assessment. Any combination of biologic therapies is acceptable. Prior chemotherapy is acceptable, but patients must have been off cytotoxic chemotherapy for at least 1 month. Patients with ER-/HER2+ disease have must be failed at least 1 line of chemotherapy in the metastatic setting.

- Estimated life expectancy of ≥ 12 weeks.
- Ability to swallow oral medications.
- Participants must have adequate organ function as defined by:
- ANC ≥1.5 x 109/L, platelet count ≥100 x 109/L, haemoglobin ≥ 10 g/dL.

- Total bilirubin \< 1.5x UNL
- ALT \& AST \< 2.5xUNL; alkaline phosphatase \< 2.5xUNL;
- Creatine phosphokinase (CPK) ≤ 2.5 x UNL
- Baseline left ventricular ejection fraction (LVEF) ≥ 50% as determined by either echocardiography (ECHO) or multi gated acquisition (MUGA) scan.
- Patients with CNS metastatic disease are allowed if the disease is controlled and stable for at least 3 months by CT or MRI.
- Negative pregnancy test within 7 days prior to study treatment start, for women of childbearing potential. Women of childbearing potential must agree to use an adequate form of contraception for the duration of their study participation

- Lack of physical integrity of the upper gastrointestinal tract, clinically significant malabsorption syndrome, or inability to take oral medications.

- Current or past infection with Human Immunodeficiency Virus (HIV), Hepatitis B virus (HBV), or Hepatitis C virus (HCV).
- Receipt of IV antibiotics for infection within 7 days of study enrollment.
- History of other malignancies within the last 2 years, except for carcinoma in situ of the cervix or basal cell carcinoma
- Participants with bone-only disease are excluded, unless a measureable lesion is present, as defined by RECIST 1.1.
