Bcl-2 Antisense Oligodeoxynucleotide G3139 and Paclitaxel in Treating Patients With Recurrent Small Cell Lung Cancer

OBJECTIVES: I. Assess the toxicity and feasibility of paclitaxel administration during continuous intravenous bcl-2 antisense oligodeoxynucleotide G3139 in patients with recurrent small cell lung cancer. II. Evaluate the clinical response of this patient population when treated with this regimen. III. Evaluate the correlation between bcl-2 expression in these patients and efficacy of this therapy.

OUTLINE: Patients are stratified according to whether they have received prior taxane therapy (yes vs no). Patients receive bcl-2 antisense oligodeoxynucleotide G3139 IV continuously on days 1-6 followed by 2 weeks of rest. Paclitaxel IV is administered over 3 hours on day 6 of each course. Treatment continues for a minimum of 2 courses in the absence of disease progression or unacceptable toxicity. Intrapatient dose escalation is allowed. Patients are followed until death.

PROJECTED ACCRUAL: A total of 19-33 patients will be accrued for this study within 12-18 months.

DISEASE CHARACTERISTICS: Histologically or cytologically confirmed small cell lung cancer Prior therapy including either cisplatin or carboplatin with progression either on therapy or within 3 months of completing therapy Bidimensionally measurable disease on CT scan or x-ray, not limited to the CNS No active CNS disease CNS metastasis allowed if measurable disease outside of CNS and completed a course of CNS radiotherapy if clinically indicated and recovered

PATIENT CHARACTERISTICS: Age: 18 and over Performance status: ECOG 0-2 OR Zubrod 0-2 Life expectancy: Not specified Hematopoietic: WBC at least 3,000/mm3 Hemoglobin at least 9 g/dL Platelet count at least 100,000/mm3 Hepatic: Bilirubin no greater than 1.5 mg/dL ALT/AST no greater than 2 times upper limit of normal (ULN) Alkaline phosphatase no greater than 2 times ULN Renal: Creatinine no greater than 1.5 mg/dL OR Creatinine clearance at least 50 mL/min Cardiovascular: No evidence of heart block greater than first degree, bundle branch block, or ventricular or supraventricular arrhythmia on EKG No clinical evidence of congestive heart failure, angina, or documented myocardial infarction within past 6 months Other: Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception No known hypersensitivity to Cremaphor EL No other significant concurrent medical or psychiatric condition that might place patient at increased risk from study
