PRIMARY OBJECTIVES: I. To assess overall survival in chemo-naϊve patients with advanced non-small cell lung cancer (NSCLC) treated with combination of gemcitabine, carboplatin and PS-341. SECONDARY OBJECTIVES: I. To assess response rate (confirmed plus unconfirmed, complete plus partial), in the subset of patients with measurable disease, progression-free survival and quantitative toxicities in this group of patients treated with this regimen. II. To investigate in an exploratory manner, the association of levels of hypoxia-induced secreted proteins and tumor DNA in plasma levels of apoptosis-associated proteins in tumor tissue, and the changes in the levels of PS-341 modulated proteins in peripheral white blood cells with patient response and survival. OUTLINE: This is a multicenter study. Patients receive gemcitabine IV over 30 minutes on days 1 and 8, carboplatin IV over 15-30 minutes on day 1, and bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients with stable or responding disease may continue to receive bortezomib alone on the above schedule for up to 1 year at the discretion of the treating physician. Patients are followed every 6 months for up to 3 years after registration. PROJECTED ACCRUAL: A total of 99 patients will be accrued for this study within 5 months.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

99 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Conditions

Criteria

Any sex

Biological sex of participants that are eligible to enroll.

Over 18 Years

Range of ages for which participants are eligible to join.

Healthy volunteers not allowed

If individuals who are healthy and do not have the condition being studied can participate.

Criteria

20 inclusion criteria required to participate

Patients must have histologically or cytologically proven selected stage IIIB (T4 lesion due to malignant pleural effusion) or stage IV, advanced non-small cell lung cancer or recurrent disease after previous surgery and/or radiation

Patients with known brain metastases are not eligible for this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; all patients must have a pretreatment CT or MRI scan of the brain to evaluate for CNS disease within 28 days prior to registration

Patients must have measurable OR non-measurable disease documented by CT, MRI, or x-ray; measurable disease must be assessed within 28 days prior to registration and non-measurable disease must be assessed within 42 days prior to registration; pleural effusions, ascites and laboratory parameters are not acceptable as the only evidence of disease

Patients must not have received any prior systemic chemotherapy or biological agent for non-small cell lung cancer; prior radiation is permitted; however, two weeks must have elapsed since the completion of prior radiation therapy and patients must have recovered from all associated toxicities at the time of registration; measurable or non-measurable disease must be outside the previous radiation field or a new lesion inside the port must be present
