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

Phase 2

Terminated

Conditions: Stage IB Non-Small Cell Lung Carcinoma
Stage IA Non-Small Cell Lung Carcinoma

Interventions: Drug: Azacitidine
Drug: Entinostat
Other: Laboratory Biomarker Analysis

Registration Number: NCT01207726

Lead Sponsor: National Cancer Institute (NCI)

Brief Summary: This study combines the deoxyribonucleic acid (DNA) methyltransferase inhibitor, 5-azacitidine (5-AZA), with an orally bioavailable histone deacetylase inhibitor, entinostat (SNDX-275), for the adjuvant treatment of patients with resected stage I non-small cell lung cancer (NCSLC).

Detailed Description: PRIMARY OBJECTIVES:

I. To assess the effect of 5-azacitidine and entinostat on the hazard of 3 year progression-free survival in patients with resected stage I non-small cell lung cancer.

SECONDARY OBJECTIVES:

I. To assess the safety, tolerability and toxicity of entinostat and 5-azacitidine in patients with resected stage I non-small cell lung cancer.

II. To explore the effect of entinostat and 5-azacitidine on median disease-free and overall survival in patients with resected stage I non-small cell lung cancer.

III. To assess the pharmacodynamic effects of 5-azacitidine and entinostat on DNA methylation and gene re-expression in patients with resected stage I NSCLC through analysis of sputum.

IV. To estimate the effect of entinostat and 5-azacitidine on progression free survival comparing patients with N2 lymph nodes categorized as methylated pre-treatment with those who are categorized as unmethylated.

V. To establish factors that predict clinical outcome in patients treated with combination epigenetic therapy by performing genome-wide analyses on pre-treatment tumor DNA.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive azacitidine subcutaneously (SC) on days 1-5 and 8-10 and entinostat orally (PO) once daily (QD) on days 3 and 10. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive standard of care.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Recruitment & Eligibility

Status: TERMINATED

Sex: All

Target Recruitment: 13

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

Arm && Interventions

Group	Intervention	Description
Arm I (azacitidine, entinostat)	Laboratory Biomarker Analysis	Patients receive azacitidine SC on days 1-5 and 8-10 and entinostat PO QD on days 3 and 10. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
Arm I (azacitidine, entinostat)	Entinostat	Patients receive azacitidine SC on days 1-5 and 8-10 and entinostat PO QD on days 3 and 10. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
Arm I (azacitidine, entinostat)	Azacitidine	Patients receive azacitidine SC on days 1-5 and 8-10 and entinostat PO QD on days 3 and 10. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures

Name	Time	Method
Disease-free Survival (DFS)	3 years	The DFS hazard rate and 95% confidence interval will be reported. At this time, event time distributions for disease-free survival in the two arms will be estimated with the method of Kaplan and Meier and compared using a stratified Cox-proportional hazards model (stratified for stage IA vs IB) with a two-sided alpha of 10%.

Secondary Outcome Measures

Name	Time	Method
Median Disease-free Survival	Up to 5 years	Determined by the method determined by Kaplan and Meier. Estimated with 95% confidence intervals. Cox proportional hazard modeling will be used for multivariate analysis.
Overall Survival	Up to 5 years	Determined by the method determined by Kaplan and Meier. Estimated with 95% confidence intervals. Cox proportional hazard modeling will be used for multivariate analysis.
Toxicities Graded According to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4.0	Up to 5 years	Simple descriptive statistics will be utilized to display the data.
Factors That Predict Clinical Outcome in Patients Treated With Combination Epigenetic Therapy in Terms of Epigenomic Data Generated From the Illumina Platform	Up to 2 years	The study was terminated early due to poor accrual since the requirement of clinic administration of the 5AZA daily and post-operative patients not wanting 6 months of treatment. For this reason, 13 pts were enrolled and data was not analyzed, for which we are unable to make any conclusions or report results.
Number of Relapses and Deaths Per Total Time of Follow-up Comparing Patients With N2 Lymph Nodes in Terms of Methylated and Unmethylated	Up to 5 years	Kaplan Meier curves will be used.
Presence of Methylation Patterns	Up to 2 years	McNemar's test will be used to compare the change in methylation after treatment in sputum.
