About

RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: This phase II trial is studying how well arsenic trioxide works in treating patients with locally advanced or metastatic non-small cell lung cancer.

Full description

OBJECTIVES:

Primary

• Determine the safety and activity of arsenic trioxide in patients with locally advanced or metastatic non-small cell lung cancer.
• Determine the qualitative and quantitative toxic effects of this drug in these patients.

Secondary

• Determine the response, in terms of objective tumor response and response duration, in patients treated with this drug.
• Determine the patterns of failure and survival in patients treated with this drug.

OUTLINE: This is a pilot study.

Patients receive arsenic trioxide IV over 1-2 hours on days 1-5 of week 1 and on days 1 and 5 of weeks 2-8 (course 1 only). Beginning with course 2 and for all subsequent courses, patients receive arsenic trioxide on days 1 and 5 of weeks 1-8. Treatment repeats every 8 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients achieving complete response (CR) receive 1 additional course of therapy beyond CR. Patients achieving CR due to local consolidative therapy (surgery or radiotherapy) receive 2 additional courses of therapy beyond CR.

Patients are followed for 1 month, every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 14-30 patients will be accrued for this study within 9-18 months.

Enrollment: 30 estimated patients

Ages: 18+ years old
