Study Assessing Safety, Pharmacokinetics and Efficacy of CC-223 With Either Erlotinib or Oral Azacitidine in Advanced Non-Small Cell Lung Cancer

Inclusion Criteria: 1. Men and women, 18 years or older, with histologically or cytologically-confirmed, Stage IIIB/IV Non-Small Cell Lung Cancer with tumor progression following at least one prior treatment regimen (either chemotherapy or an Epidermal Growth Factor Receptor inhibitor) for advanced disease. There is no restriction on the number of prior treatment regimens allowed. 2. Eastern Cooperative Oncology Group Performance Score of 0 to 1. 3. Adequate organ function. 4. Adequate contraception (if appropriate). 5. Consent to retrieve archival tumor tissue. 6. Consent to repeated tumor biopsy (dose expansion phase). Exclusion Criteria: 1. Prior systemic cancer-directed treatments or investigational drugs within 4 weeks or 5 half lives, whichever is shorter except erlotinib which may be continued with intervention in subjects allocated in Arm A. 2. Symptomatic central nervous system metastases. 3. Acute or chronic pancreatitis. 4. Persistent diarrhea or malabsorption \> Grade 2, despite medical management. 5. Impaired cardiac function or significant cardiac disease. 6. Diabetes on active treatment, fasting blood glucose \> 126 mg/dL, HbA1c \> 6.5%. 7. Known Human Immunodeficiency Virus, chronic hepatitis B or C infection. 8. Prior treatment with an investigational dual TORC1/TORC2, PI3K, or Akt inhibitor. Prior treatment with rapalogs is allowed. 9. Major surgery \< 2 weeks prior to starting study drugs. No specific wash out is required for radiotherapy. Subjects must have recovered from any effects of recent therapy that might confound the safety evaluation of study drug. 10. Pregnant or breastfeeding, inadequate contraception. 11. History of concurrent second malignancies requiring ongoing systemic treatment.
