Brief summary:
This phase II trial is studying how well suberoylanilide hydroxamic acid works in treating patients with stage IIIB, stage IV, or recurrent non-small cell lung cancer. Drugs used in chemotherapy, such as suberoylanilide hydroxamic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Suberoylanilide hydroxamic acid may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description:
PRIMARY OBJECTIVES:

I. To evaluate the response of non-small cell lung cancer to SAHA in the second line setting by applying RECIST criteria.

SECONDARY OBJECTIVES:

I. To estimate the time to progression and overall survival in this patient population.

II. To examine the toxicity profile of SAHA.

TERTIARY OBJECTIVES:

I. To evaluate the molecular activity of SAHA by evaluating its effect on histone acetylation, upregulation of target genes, generation of reactive oxygen species, apoptosis and correlation with P53 status.

II. To explore gene expression profiles that predict response to SAHA.

OUTLINE: This is a multicenter study.

Patients receive oral suberoylanilide hydroxamic acid once daily on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed at 1 month and then every 3 months for 1 year or until disease progression.

Arms:
arm 1: Patients receive oral suberoylanilide hydroxamic acid once daily on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
