Criteria

Inclusion Criteria:

Each patient must meet all of the following inclusion criteria to be enrolled in the study:

1. Male or female patients 18 years or older.

2. Dose Escalation Cohort: Patients must have a diagnosis of a histologically confirmed solid tumor that is incurable and refractory to standard therapy or for which no standard therapy exists.

3. Dose Expansion Cohort Group 1 and 2: Patients must have a diagnosis of histologically confirmed metastatic TNBC defined as negative for estrogen receptor, progesterone receptor and HER2.

For men, even if surgically sterilized (ie, status post-vasectomy), they must:

• Agree to practice effective barrier contraception during the entire study treatment period and through 120 days after the last dose of study drug, OR agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the patient (Periodic abstinence [e.g, calendar, ovulation, symptothermal, postovulation methods for the female partner] and withdrawal are not acceptable methods of contraception

1. Bone marrow reserve consistent with: absolute neutrophil count (ANC) ≥ 1.5 x 109/L; platelet count ≥ 100 x 109/L; hemoglobin ≥ 9 g/dL. Values must be obtained without the need for myeloid growth factor support, platelet or PRBC transfusion support within 14 days.

2. Hepatic: total bilirubin ≤ 1.5 x upper limit of normal (ULN), transaminases (aspartate aminotransferase/serum glutamic oxaloacetic transaminase-AST/SGOT and alanine aminotransferase/serum glutamic pyruvic transaminase-ALT/SGPT) ≤ 2.5 x ULN (≤ 5 x ULN if liver metastases are present);

3. Renal: Creatinine < 1.5 X ULN or creatinine clearance ≥ 50 mL/min based either on Cockroft-Gault estimate or based on urine collection (12 or 24 hour)(Appendix 2);

4. Metabolic: Glycosylated hemoglobin (HbA1c)<7.0%, fasting serum glucose (≤ 130 mg/dL) and fasting triglycerides ≤ 300 mg/dL;

5. For patients undergoing serial tumor biopsies, INR and activated partial thromboplastin time (PTT) must be within 1.5 X the upper limit of normal.

11. Left ventricular ejection fraction (LVEF) > LLN of the institutional standard of normal as measured by echocardiogram (ECHO) or multiple gated acquisition scan (MUGA) within 4 weeks prior to first study drug administration.

12. Ability to swallow oral medications.

13. Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.

14. Patients who have a history of brain metastasis are eligible for the study provided that all the following criteria are met:

1. Brain metastases which have been treated
