Docetaxel With Either Cetuximab or Bortezomib as First-Line Therapy in Treating Patients With Stage III or Stage IV Non-Small Cell Lung Cancer

PRIMARY OBJECTIVES:

I. To evaluate the progression free survival (PFS), defined as the time between study entry and disease progression or death, for each of the two combination regimens.

SECONDARY OBJECTIVES:

I. To determine the overall response rate of each regimen. II. To evaluate the overall survival distributions associated with each regimen.

III. To evaluate the toxicities of each regimen.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive docetaxel IV over 30 minutes on days 1, 8, and 15 and cetuximab IV over 1-2 hours on days 1, 8, 15, and 22. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients with responding or stable disease after 4 courses receive cetuximab alone as above in the absence of disease progression or unacceptable toxicity.

Arm II: Patients receive docetaxel as in arm I and bortezomib IV over 3-5 seconds on days 1, 8, and 15. Treatment repeats every 28 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients with responding or stable disease after 4 courses receive bortezomib alone as above in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed monthly for 1 year, every 2 months for 2 years, and then every 4 months for 3 years.

PROJECTED ACCRUAL: A total of 62 patients (31 per treatment arm) will be accrued for this study within 6-11 months.

Inclusion criteria

• All patients must have histologically or cytologically documented non-small cell carcinoma of the lung (adenocarcinoma, large cell, squamous, or mixtures of these types)
• Patients with stage IV disease are eligible
• Patients with stage IIIB due to a malignant pleural effusion or supraclavicular node involvement are eligible (IIIB patients eligible for CALGB protocols of combined chemotherapy and thoracic radiotherapy are not eligible)
• Patients with known CNS metastases who have received therapy (surgery, XRT, gamma knife), and are neurologically stable and off steroids by the time of enrollment are eligible if they are not on enzyme-inducing anticonvulsants; patients with leptomeningeal disease are not eligible
• Documentation of PS 2 must be noted on form C-1392
• Patients must have measurable or non-measurable disease
• Measurable disease (target lesions): lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 20 mm with conventional techniques or as ≥ 10 mm with spiral CT scan
• Non-measurable disease (non-target lesions): all other lesions, including small lesions (longest diameter < 20 mm with conventional techniques or < 10 mm with spiral CT scan) and truly nonmeasurable lesions; lesions that are considered non-measurable include the following:

• Bone lesions
• Ascites
• Pleural/pericardial effusion
• Lymphangitis cutis/pulmonis
• Abdominal masses that are not confirmed and followed by imaging techniques
• Cystic lesions
• No prior systemic treatment for advanced NSCLC is permitted; prior treatment for early-stage disease (adjuvant) or for locally-advanced stage III disease is allowed if completed at least 12 months prior to registration
• Patients must have recovered (all toxicities ≤ grade 1) from prior surgery and/or radiotherapy
• No prior therapy which specifically and directly targets the EGFR pathway
• No prior severe infusion reactions to a monoclonal antibody
• No ≥ grade 2 peripheral neuropathy
• Non-pregnant and non-nursing
• No concurrent treatment with any other investigational therapy
• Granulocytes ≥ 1,500/μl
• Platelets ≥ 100,000/μl
• Serum creatinine ≤ ULN
• Bilirubin ≤ ULN
• AST ≤ ULN
