Clinical Trial Summary

This study is being done to compare a special type of Positron Emission Tomography (PET) scan with CT scan in patients with surgically removable lung cancer to see which method is more useful in measuring a response to treatment. A PET scan uses small amounts of radioactive material injected into the blood to show the internal workings of the body. In this study, we will use two radioactive materials: 18F-FLT (referred to as FLT) and 18F-FDG (referred to as FDG). FDG is used routinely in the staging of lung cancer and is approved by the FDA for that purpose. FLT is used in the special type of PET scan being assessed by this study. In addition the study will assess the effects of the combination of docetaxel and cisplatin (chemotherapeutic drugs) on certain pathological characteristics of the tumor. The combination of docetaxel and cisplatin is approved by the Food and Drug Administration (FDA) for the treatment of advanced/metastatic NSCLC (non-small cell lung cancer). It is not approved for use in patients who have surgically removable NSCLC. In such cases cisplatin is used as a single drug therapy before surgery. The FDA is allowing the use of docetaxel along with cisplatin in this research study.

Description:

PRIMARY OBJECTIVES:

I. To determine if the absolute decrease measured in primary tumor 18 F-F-3'-fluoro-3'-deoxy-L-thymidine (FLT) uptake (standard uptake value [SUV] and influx constant [Ki]) between pre-treatment imaging and imaging after the first cycle of therapy differs in patients categorized as responders or non-responders based on Response Evaluation Criteria in Solid Tumors (RECIST) measured with computed tomography (CT) after the second cycle of therapy.

SECONDARY OBJECTIVES:

I. To determine if the absolute decrease measured in primary tumor FDG uptake (SUV) between pre-treatment imaging and imaging after the first cycle of therapy differs in patients categorized as responders or non-responders based on RECIST measured with CT after the second cycle of therapy.

II. To assess the effects of the combination of docetaxel and cisplatin on fractional tumor viability and proliferative fraction pre and post treatment and to correlate these with the PET SUV data for both tracers.

III. To assess the methylation status of the checkpoint with forkhead and ring finger domains gene (CHFR) gene from pre-treatment tumor biopsies and correlate methylation status post treatment with clinical and pathologic response.

OUTLINE:

Patients receive docetaxel intravenously (IV) and cisplatin IV on day 1 and dexamethasone orally (PO) twice daily (BID). Treatment repeats every 3 weeks for 2 courses in the absence of disease progression or unacceptable toxicity. Patients undergo FDG PET/CT, FLT PET/CT, and thoracic CT at baseline and the end of courses 1 and 2 and then undergo surgery.

After completion of study treatment, patients are followed up for 4-6 weeks.

• Patients must be surgically resectable as determined by a thoracic surgeon

• Patients must have measurable disease per RECIST 1.1, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 10 mm with spiral CT scan

• Life expectancy of greater than 12 weeks

• ECOG performance status < 1

• Leukocytes >= 3,000/uL

• Absolute neutrophil count >= 1,500/uL

• Platelets >= 100,000/uL

• Total bilirubin =< 1.5 x institutional upper limit of normal

• AST (SGOT) =< 1.5 x institutional upper limit of normal

• Alkaline phosphatase =< 2.5 x institutional upper limit of normal

• Creatinine =< 1.5 x institutional upper limit of normal OR creatinine clearance >= 60 mL/1.73 m2 for patients with creatinine levels above institutional normal

• Fasting screening blood glucose =< 200 mg/dL

• Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with either agent

Exclusion Criteria:

• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately

• Patients must not have received prior systemic chemotherapy or radiation therapy for lung cancer; prior systemic chemotherapy or radiation for other malignancies over three years prior to study enrollment may be allowed at the discretion of the principal medical investigator

• Prior malignancy in the past 3 years, other than non-melanoma skin cancer and in situ carcinoma of the cervix

• Patients who report a hearing deficit at baseline, even if it does not require a hearing aid or intervention, or interfere with activities of daily life (Common Terminology Criteria for Adverse Events [CTCAE] grade 2 or higher)

• Peripheral neuropathy > CTCAE grade 1

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to cisplatin, docetaxel, or other agents used in the study

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, uncontrolled diabetes, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric/social situations that would limit compliance with study requirements

• HIV-positive patients on combination antiretroviral therapy are ineligible

• Inability to comply with study and/or follow-up procedures

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in FLT uptake	Will be utilized as a continuous variable.	Baseline and 6 weeks	No
Primary	Change in FLT uptake (measured in quantitative SUVs and Ki)	Will be calculated by subtracting the uptake of the scan after the first cycle of chemotherapy from the uptake of the pre-treatment scan.	Baseline and 6 weeks	No
Primary	Change in FLT uptake in responders and non-responders	Unadjusted analysis will be performed utilizing students t-tests. If the data appears non-normal, the Wilcox on rank-sum test will be used rather than the t-test. Adjusted analysis will be performed utilizing logistic regression.	Baseline and 6 weeks	No
