Phase II Study Of TLK286 For The Treatment Of Advanced Non-Small Cell Lung Cancer
Phase II Study Of TLK286 For The Treatment Of Advanced Non-Small Cell Lung Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: Phase II trial to study the effectiveness of TLK286 in treating patients who have advanced non-small cell lung cancer.
OBJECTIVES: I. Determine the 12-month survival of patients with advanced non-small cell lung cancer treated with TLK286. II. Determine the overall survival of patients treated with this drug. III. Determine the objective response rate, duration of objective response, time to tumor progression, and disease stabilization in patients treated with this drug. IV. Determine the safety of this drug in these patients.
OUTLINE: This is a multicenter study. Patients receive TLK286 IV over 30 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients are followed every 6 weeks for 1 year and then every 12 weeks thereafter.
PROJECTED ACCRUAL: Approximately 55 patients will be accrued for this study within 12 months.
DISEASE CHARACTERISTICS: Histologically confirmed non-small cell lung cancer (NSCLC), including: Squamous cell carcinoma Undifferentiated carcinoma Adenocarcinoma Mixed (i.e., adenocarcinoma with squamous cell carcinoma) No mixed tumors containing small cell lung carcinoma elements Bronchoalveolar carcinoma Large cell carcinoma Bronchoalveolar lavage allowed for diagnosis Advanced or metastatic NSCLC Stage IIIB disease ineligible for combined chemotherapy and radiotherapy OR Stage IV disease Progressive NSCLC during or after first-line therapies with platinum-containing chemotherapy regimens in the advanced or metastatic setting Measurable disease by radiological imaging techniques Previously treated CNS metastases allowed provided: Neurologically stable Oral or IV steroids or anticonvulsants not required No active disease by CT scan or MRI No known leptomeningeal metastases or carcinomatous meningitis
PATIENT CHARACTERISTICS: Age: 18 and over Performance status: ECOG 0-1 Life expectancy: At least 12 weeks Hematopoietic: Absolute neutrophil count at least 1,500/mm3 Platelet count at least 100,000/mm3 Hemoglobin at least 9.0 g/dL Hepatic: Bilirubin no greater than 2.0 mg/dL ALT and AST no greater than 3 times upper limit of normal (ULN) (5 times ULN if liver metastases present) Renal: Creatinine no greater than 1.5 mg/dL OR Creatinine clearance at least 60 mL/min No gross hematuria Cardiovascular: No uncontrolled cardiac arrhythmia No myocardial infarction within the past 6 months Other: No other malignancy within the past 5 years except adequately treated carcinoma in situ of the cervix or basal cell or squamous cell skin cancer No severe concurrent disease, infection, or comorbidity that would preclude study No other unstable medical conditions No psychiatric disorders that would preclude study Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception during and for at least 6 months after study
