4. ECOG Performance status 0-1
5. A minimum life expectancy of 12 weeks
6. Adequate bone marrow, hepatic and renal function as evidenced by:

   * Absolute neutrophil count (ANC) \> 1.5 x 109/L
   * Platelet count \> 100 x 109/L
   * Hemoglobin \> 9.0 g/dL

7. Female patients who are known to be capable of conception should have a negative serum pregnancy test (beta-human chorionic gonadotropin (β-hCG)) within 1 week of starting the study
8. All potentially fertile patients will agree to use an effective form of contraception during the study and for 90 days following the last dose of NOX66 (an effective form of contraception is defined as an oral contraceptive or a double barrier method
9. At least 4 weeks must have elapsed prior to commencement of NOX66 treatment since prior chemotherapy, investigational drug or biologic therapy and any toxicity associated with these treatments has recovered to ≤ NCI-CTCAE Grade 1
10. At least 21 days must have elapsed prior to Day 1 Cycle 1 since radiotherapy (limited palliative radiation is allowed \> 2 weeks), immunotherapy or following major surgery and any surgical incision should be completely healed

Exclusion Criteria:

4. Patients with QTc of \> 470 msec on screening ECG. (If a patient has QTc interval \>470 msec on screening ECG, the screening ECG may be repeated twice (at least 24 hours apart). The average QTc from the 3 screening ECGs must be \<470 msec in order for the patient to be eligible for the study.
5. Any major surgery, radiotherapy, or immunotherapy within the last 21 days (limited palliative radiation is allowed \> 2 weeks).
