4. Patients must have recovered for at least 3 weeks from prior treatment regimens and have no residual toxicity > Grade 2 (with the exception of peripheral neuropathy which must have improved to ≤ Grade 1).
5. Patient should have full recovery from any reversible side effects of prior chemotherapy.
6. Patient should have full recovery for at least 4 weeks since major surgery.
7. ECOG performance status 0-2.
8. Age ≥18 years.

9. Patient must have the following blood counts at Baseline:

   • WBC ≥ 3.0 x 10 cells/L.
   • ANC ≥ 1.5 x 10 cells/L.
   • Platelets ≥ 100 x 10 cells/L.
   • Hgb ≥ 9grams/dL.

10. Patient must have the following blood chemistry levels at Baseline:

    • AST (SGOT), ALT (SGPT) ≤ 1.5x upper limit of normal range (ULN);
    • Total Bilirubin ≤ ULN;
    • Alkaline phosphatase ≤ 2.5x ULN (unless bone metastasis is present in the absence of liver metastasis;
    • Creatinine ≤ 1.5 mg/dL
11. Peripheral neuropathy Grade ≤ 1 by NCI CTCAE V3.0.
12. Female of childbearing potential with negative serum pregnancy test within 72 hours prior to the first dose of study drug.

14. Life expectancy ≥ 3 months.
15. Informed consent document has been obtained.
16. If obese, a patient must be treated with doses calculated using his/her actual BSA (the physician must be comfortable treating at the full BSA dose regardless of BSA).

Exclusion Criteria: Subjects who meet any of the following criteria will be excluded from the study.

1. Concurrent therapy (chemotherapy, hormonal therapy, kinase inhibitors, immunotherapy, etc) for advanced solid tumor.
2. Patients receiving known CYP450 3A4 inhibitors.
3. Bisphosphonate therapy is allowed, however, patients should be stable on their current bisphosphonate, with no change, start or stop of treatment within 4 weeks prior to enrollment.
4. Patients with known brain metastases or leptomeningeal tumor involvement should be excluded from this clinical trial.
5. Uncontrolled intercurrent illness including, but not limited to, serious ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/ social situations that would limit compliance with study.
6. Patients with significant cardiovascular disease including congestive heart failure (New York Heart Association Class III or IV), active angina pectoris or recent myocardial infarction (within the last 6 months).
7. History of other malignancy within the last 5 years which would affect the diagnosis or assessment of advanced solid tumor excluding non-melanomatous skin cancer and cervical carcinoma.
8. Patients who have received an investigational drug within the previous 3 weeks.
9. Patient is currently enrolled in any other clinical study in which investigational procedures are performed or investigational therapies are administered. A patient may not enroll in such clinical trials while participating in this study.
10. Pregnant or nursing women.
11. Patients with history of allergy or hypersensitivity to the study drug or its excipients.
12. Patients with marked baseline prolongation of QT/QTc interval (>450 milliseconds).
