A Phase Ib Expansion Study Investigating the Safety, Efficacy, and Pharmacokinetics of Intravenous CUDC-101 in Subjects With Advanced Head and Neck, Gastric, Breast, Liver and Non-small Cell Lung Cancer Tumors

Inclusion Criteria:

* Subjects with histopathologically confirmed diagnosis of advanced breast, gastric, head and neck, liver and non-small cell lung cancer.

  * For subjects with non-small cell lung cancer only:

    * Most recent treatment must be erlotinib and subjects must have had a radiographic partial or complete response to treatment as defined by RECIST criteria and should be currently progressing after the documented response.
    * A documented mutation in EGFR exons 19 or 21
* Subjects must have no further standard of care options or have refused standard therapy
* Measurable or evaluable disease
* Age ≥ 18 years
* ECOG performance \< 2
* Life expectancy ≥ 3 months
* If female, neither pregnant or lactating
* If of child bearing potential, must use adequate birth control
* Absolute neutrophil count ≥ 1,500/µL; platelets ≥ 100,000/µL;
* Creatinine ≤ 1.5x upper limit of normal (ULN) or calculated creatinine clearance ≥ 60mL/min/1.73m2
* Total bilirubin ≤ 1.5x ULN; AST/ALT ≤ 2.5x ULN. In subjects with documented liver metastases, the AST/ALT may be ≤ 5x ULN
* Prothrombin time ≤1.5x ULN, unless receiving therapeutic anticoagulation
* Serum magnesium and potassium within normal limits (may use supplements to achieve normal values)
* Subjects with brain metastases are eligible if controlled on a stable dose ≤ 10mg prednisone/day or its equivalent dose of steroids
* Able to render informed consent and to follow protocol requirements.

Exclusion Criteria:

* Anticancer therapy within 4 weeks of study entry.
* Use of investigational agent(s) within 30 days of study entry
* History of cardiac disease with a New York Heart Association (NYHA) Class II or greater congestive heart failure (CHF), myocardial infarction (MI) or unstable angina in the past 6 months prior to Day 1 of treatment, serious arrhythmias requiring medication for treatment.
* Known infection with human immunodeficiency virus (HIV), hepatitis B or hepatitis C. Subjects with liver cancer and hepatitis may be eligible.
