Clinical Trial Summary

The primary objective for this trial is to determine the biological ability of apricoxib to decrease T reg cells in the peripheral blood and tumor infiltrating lymphocytes in subjects compared to those who have not in subjects with early stage Non-small Cell Lung Cancer (NSCLC). The secondary objectives are to determine the efficacy of apricoxib to inhibit CD4+CD25+ T reg and FOXP3 function and exploration of COX-2 dependent biomarkers of apoptosis resistance, angiogenesis, invasion, and immunity.

• Required concurrent use of COX-2 inhibitors or other NSAIDS during Apricoxib administration.

• Chronic or concurrent use of steroids (topical steroids are acceptable if medically indicated).

• Pregnant or nursing women.

• Evidence of NYHA class III or greater cardiac disease.

• History of myocardial infarction, stroke, ventricular arrhythmia, or symptomatic conduction abnormality within 12 months of initiating treatment.

Intervention

Drug:
• Apricoxib
As part of the trial, forty eligible subjects will be randomly assigned to receive Apricoxib 400 mg orally once daily or no drug intervention for a 7 day period (Days 0-6) prior to surgical resection of the lung tumor but between the two surgeries.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Compare Level of CD4+CD25high T Lymphocyte Regulatory Cells in Peripheral Blood Lymphocytes and Tumor Infiltrating Lymphocytes From Surgical Resection Specimens of Subjects With Early Stage NSCLC Who Have Received Apricoxib to Those Who Have Not	As part of the trial, forty eligible subjects will be randomly assigned to receive Apricoxib 400 mg orally once daily or no drug intervention for a 7 day period (Days 0-6) prior to surgical resection of the lung tumor but between the two surgeries. Peripheral blood and urine will be obtained on Days 0 and 7 from both groups (prior to surgical incision). Bronchoalveolar lavage (BAL) and lymph node tissue will be obtained on Days 0 and 7. TIL will be obtained from surgical resection specimens of the primary lung tumor only on Day 7	7 days
Secondary	Effect of Apricoxib on Levels of CD4+CD25+ T Regulatory Cells in Peripheral Blood.Also,Biomarkers of Apoptosis Resistance,Angiogenesis,Invasion and Immunity Will be Tested in the Lab to Check How Effective Apricoxib is in Inhibiting These Proteins.	Peripheral blood from patients with NSCLC has been reported to have an increase in the percentages of CD4+CD25+ T reg cells.In contrast <10% of the PBLs of normal donors have this phenotype. As such, CD4+CD25+ cells will be assessed in addition to FOXP3 levels in PBL. In addition, exploration of COX-2 dependent biomarkers of apoptosis resistance, angiogenesis, invasion, and immunity will be studied. COX-2, FOXP3, IL-10, IL-12, MDC, CXCR4 and survivin will be analyzed in plasma.	7 days
