CI-1040 in Treating Patients With Advanced Breast, Colon, Pancreatic, or Non-Small Cell Lung Cancer

OBJECTIVES:

• Determine the antitumor activity of CI-1040 in patients with non-small cell lung, breast, colon, or pancreatic cancer.
• Determine the safety profile of this drug in these patients.
• Assess quality of life (overall and for each tumor type) of patients treated with this drug.
• Determine the relationship between study drug concentration and antitumor response in these patients and target suppression and safety of this drug.
• Correlate target suppression (pERK) with antitumor effects of this drug in these patients.
• Correlate the mRNA expression profile of the tumors with antitumor effects of this drug in these patients.

OUTLINE: This is a multicenter study. Patients are stratified according to tumor type (non-small cell lung vs breast vs colon vs pancreas).

Patients receive oral CI-1040 twice daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline and then every 28 days during the first 6 months of study therapy.

Patients are followed every 2 months.

PROJECTED ACCRUAL: A total of 52-172 patients (13-43 per stratum) will be accrued for this study.

DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed metastatic or inoperable non-small cell lung, breast, or colon cancer or duct cell carcinoma of the exocrine pancreas
