Patients with body mass index >25, or FBG 110-140mg/dL, or HbA1C 5.7 - 6.4% should be agreeable for low glycemic diet and lifestyle modifications, and consulted by nutritionist prior to initiation of the study drugs. Ability to understand and the willingness to sign a written informed consent and comply with the study scheduled visits, treatment plans, laboratory tests and other procedures.
Exclusion criteria:
- Patients with contraindications to undergo contrast MRI imaging of the brain are excluded from the study
- Pregnancy or breast feeding
- Any systemic anti-cancer therapy (including hormonal therapy or investigational agents) or surgery in <14 days prior to the first dose of study treatment WBRT in <21 days, SBRT for CNS disease in <7 days, or palliative radiation to extracranial sites in <14 days prior to the first dose of study treatment5.
- Based on screening brain MRI, patients must not have any of the following:
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 dose of ≤ 2 mg total daily of dexamethasone (or equivalent) may be eligible with discussion and approval by the medical monitor 3. Any brain lesion thought to require immediate local therapy, including (but not limited to) a lesion in an anatomic site where increase in size or possible treatment-related edema may pose risk to patient (e.g. brain stem lesions). Patients who undergo local treatment for such lesions identified by screening contrast brain MRI may still be eligible for the study based on criteria described under CNS inclusion criteria 3b 4. Known or suspected leptomeningeal disease as documented by the investigator 5. Have poorly controlled (> 1/week) generalized or complex partial seizures, or manifest neurologic progression due to brain metastases notwithstanding CNS-directed therapy 5. Any toxicity related to prior cancer therapies that has not resolved to ≤ Grade 1, with the exception of peripheral neuropathy, which must have resolved to ≤ Grade 2, and alopecia 6. More than 1 line of therapy containing tucatinib, lapatinib, neratinib, afatinib, pyrotinib, or other EGFR or HER2 tyrosine kinase inhibitor in the metastatic setting. Note: receiving the above medications for <30 days is not considered to be a "line of therapy". Adjuvant treatment with EGFR or HER2 tyrosine kinase inhibitors does not count.
7. Previous treatment with alpelisib or other PI3K, mTOR or AKT inhibitor of more than 30 days duration.
8. An established diagnosis of diabetes mellitus type I, or uncontrolled diabetes mellitus type II 9. History of acute pancreatitis within 1 year of screening, or a past medical history of chronic pancreatitis 10.

Patients with history of treated and cured HCV infection may enroll if they have documented undetectable viral load.
13. Known HIV infection with CD4+ T-cell (CD4+) counts < 350 cells/μL. Note: pretesting is not required. Patients with known HIV infection and CD4+ T-cell (CD4+) counts ≥ 350 cells/μL may enroll.
14. Inability to swallow pills or any significant gastrointestinal disease which would preclude the adequate oral absorption of medications 15. Use of prohibited medications listed in the Appendix D (strong CYP3A4 inducers or inhibitors, and strong CYP2C8 inducers or inhibitors) within 3 elimination half-lives prior to initiation of study treatments 16. Myocardial infarction, severe/unstable angina, percutaneous transluminal coronary angioplasty/stenting (PTCA), or coronary artery bypass graft (CABG) within 6 month of the first dose of the study treatment 17. Clinically significant cardio-vascular disease, such as ventricular arrhythmia requiring therapy, uncontrolled hypertension (defined as persistent systolic blood pressure > 160 mm Hg and/or diastolic blood pressure > 100 mm Hg on antihypertensive medications), or any history of symptomatic congestive heart failure (CHF) 18. Other severe acute or chronic medical or psychiatric conditions or laboratory abnormalities that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, or in the judgment of the investigator would make the subject inappropriate for entry into the study.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: Ib Safety Cohort /II Expansion Cohort
In phase Ib, the tolerability of tucatinib and alpelisib combination will be confirmed and maximum tolerated dose determined.
Therapy will be administered in 28 day cycles of tucatinib 300 mg PO BID and alpelisib 250 mg PO daily (dose level 1).
Treatment will continue until unacceptable toxicity, disease progression, withdrawal of consent, or study closure.
Fulvestrant will also be administered in patients with HR+/HER2+ metastatic breast cancer.
Once RP2D is determined, the study will be continued to phase II, and new patients will enroll at RP2D.
All patients in phase IB part, who are remaining on study at the time of initiation of phase II, will be rolled over to phase II.
At that time, their study drug doses will be modified as follows: (1) if a patient is on the drug doses lower than RP2D, doses will not be increased; (2) if a patient is on a higher doses compared to RP2D, doses of study drugs will be changed to RP2D.
