Criteria

Inclusion Criteria:

2. Relapsed or refractory disease (Stage III or IV): NSCLC or pancreatic cancer must have failed at least 1 prior treatment. Breast cancer must have failed at least 2 prior treatments.

3. Measurable lesion by RECIST 1.1

4. Adequate hematologic function:

• ANC >1500 cells/mm3

• Platelet count >100,000 cells/mm3

5. Adequate hepatic and renal function:

• AST and ALT ≤2.5 x ULN for subjects without liver metastases and ≤3.5 x ULN for subjects with liver metastases

• Bilirubin ≤1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin)

• Creatinine ≤2.0 x ULN and Creatinine Clearance ≥40 mL/min (Cockcroft-Gault or 24-hour creatinine clearance collection)

2. A history of CNS involvement except as follows: Subjects with previously treated CNS metastases that are adequately treated with whole brain radiotherapy, that are neurologically stable, and do not require corticosteroids for symptomatic management for at least 14 days prior to first dose of study drug. There must be no clear evidence of radiographically active disease for at least 90 days prior to enrollment.

3. Anti-tumor therapy within 21 days of study Day 1
