Azacitidine and Entinostat in Treating Patients With Stage I Non-Small Cell Lung Cancer That Has Been Removed By Surgery

Inclusion Criteria:

• Patients must be status post complete (R0) surgical resection of pathologically-proven NSCLC (stage IA-IB according to AJCC version 7)
• Patients must be at least 4 weeks out from completion of surgery
• Eastern Cooperative Oncology Group (ECOG) performance status =< 2
• Absolute neutrophil count >= 1,000/mcL
• Platelets >= 100,000/mcL
• Total bilirubin =< 1.5 X institutional upper limit of normal
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase [SGPT]) =< 2.5 X institutional upper limit of normal
• Creatinine =< 1.5 X institutional upper limit of normal
• The effects of entinostat and 5-azacitidine on the developing human fetus at the recommended therapeutic dose are unknown; for this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
• Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

• Patients must be within 8 weeks of completing surgery
• Patients who have received prior chemotherapy or radiation for treatment of their current diagnosis of lung cancer
• Patients with sub-lobar resections (ie: wedge resection or segmentectomy)
• Patients without mediastinal lymph node specimens from mediastinoscopy or surgery (at least level R4 or 7 for right sided tumors OR at least level 5, 6 or 7 for left sided tumors)
• Patients may not be receiving any other investigational agents
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to entinostat, 5-azacitidine or other agents used in the study
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study because entinostat and 5-azacitidine are agents with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with entinostat or 5-azacitidine, breastfeeding should be discontinued if the mother is treated on this protocol; these potential risks may also apply to other agents used in this study
• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with entinostat or 5-azacitidine; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy
