Azacitidine in Treating Patients With Stage IV or Recurrent Non-small Cell Lung Cancer

This pilot phase I trial studies the side effects and best dose of azacitidine in treating patients with lung cancer that is stage IV or has returned after previous treatments (recurrent). Azacitidine is a drug used in chemotherapy that may stop tumor cells from growing or spreading by activating genes that help prevent cancer growth, called tumor suppressor genes. As people age, these genes are silenced by a chemical reaction that occurs naturally in the body, or by exposure to environmental factors such as smoking. Azacitidine may help reverse this process and restore the function of the tumor suppressor genes. Delivering azacitidine directly into the lungs by inhalation may work better in treating lung cancer.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) and toxicity of inhaled Vidaza® (azacitidine) with special emphasis on pulmonary toxicity.

SECONDARY OBJECTIVES:

I. To evaluate the pharmacokinetics of inhaled Vidaza®. II. To determine the changes in global methylation patterns in the bronchial epithelium (bronchial tissue samples) pre and post treatment.

III. To determine the changes in methylation patterns in the exhaled breath. IV. To evaluate the efficacy of inhaled Vidaza® on intra-thoracic tumors (response rate by Response Evaluation Criteria in Solid Tumors \[RECIST\] criteria for intrapulmonary lesions).

V. To estimate the progression free, intra-thoracic tumor progression free and overall survival.

VI. To determine the minimum effective dose of inhaled Vidaza® required to induce changes in the methylation status and re-expression of a panel of genes, including 5 candidate tumor suppressor genes (cyclin-dependent kinase inhibitor 2A \[p16\], h-cadherin \[H-Cad\], opioid binding protein/cell adhesion molecule-like \[OPCML\], secreted frizzled-related protein 1 \[SFRP-1\], and ras association domain family 1 \[RASSF1A\]) that are silenced in 20-50% of bronchial tissue of heavy smokers with lung cancer.

OUTLINE: This is a dose-escalation study.

Patients receive azacitidine via nebulizer over 20 minutes once daily (QD) on days 1-5 and 15-19. Treatment repeats every 28 days for up to 24 weeks in the absence of disease progression or unacceptable toxicity. Patients may continue treatment on a case-by-case basis at the discretion of principal investigator and Institutional Review Board.

After completion of study treatment, patients are followed up at 4-6 weeks and then every 3 months thereafter.

Eligibility Criteria:
Inclusion Criteria:

* Pathologically proven (either histologic or cytologic) diagnosis of stage IV or recurrent non-small cell lung cancer (according to American Joint Committee on Cancer \[AJCC\] staging, 7th edition)

* Patient must sign study specific informed consent prior to study entry
* Women of childbearing potential must have:

  * A negative serum or urine pregnancy test (sensitivity =\< 25 IU human chorionic gonadotropin \[HCG\]/L) within 72 hours prior to the start of study drug administration
  * Persons of reproductive potential must agree to use and utilize an adequate method of contraception throughout treatment and for at least 4 weeks after study drug is stopped prior to study enrollment, women of childbearing potential must be advised of the importance of avoiding pregnancy during trial participation and the potential risk factors for an unintentional pregnancy

Exclusion Criteria:

* Concomitant disease or condition that could interfere with the conduct of the study, or that would, in the opinion of the investigator, pose an unacceptable risk to the patient in this study
* Contraindication to or unwillingness to undergo study related procedures including a repeat bronchoscopy
* Participation in an investigational drug or device study or treatment with any antineoplastic agent within 14 days of the first day of dosing on this study

  * Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease)
  * Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies)
* History of hypersensitivity to mannitol
* Unwillingness or inability to comply with the study protocol for any other reason
* Women who:

  * Are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for at least 4 weeks after cessation of study drug, or
  * Have a positive pregnancy test at baseline, or
  * Are pregnant or breastfeeding
* Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious) illness
