The purpose of this study is to determine if the addition of vandetanib to a standard chemotherapy regimen will slow or stop the growth of the cancer for a longer period of time compared to the time period generally gained from the use of standard chemotherapy alone

The purpose of this trial is to determine the effectiveness of selenium in preventing the development of second primary lung tumors in patients who have undergone surgery to remove stage I non-small cell lung cancer.

Wedge resection or segmentectomy may be less invasive types of surgery than lobectomy for non-small cell lung cancer and may have fewer side effects and improve recovery.

This study will compare the anti-tumor efficacy of apricoxib and erlotinib with placebo and erlotinib as measured by time to disease progression to test the hypothesis that down regulation of COX-2 and EGFR pathways in patients with up-regulated COX-2 expression in tumor will have a clinical benefit compared with erlotinib alone.

Determine whether the addition of CP 751,871 in combination with paclitaxel plus carboplatin prolongs survival in patients with locally advanced (Stage IIIB with pleural effusion) or metastatic (Stage IV or recurrent) NSCLC of non adenocarcinoma histology.

The objective of this study is to test a clinical benefit of the addition of CP 751,871 to erlotinib therapy in patients with advanced NSCLC of non adenocarcinoma histology. The primary endpoint is Overall Survival (OS).
