- Registration Number
- NCT01673711
- Lead Sponsor
- University of Minnesota
- Brief Summary
This clinical trial studies deuterated phenanthrene tetraol in smokers who are at high risk for lung cancer. Studying samples of urine in the laboratory from smokers who are at high risk for lung cancer may help doctors learn more about biomarkers related to cancer.
- Detailed Description
PRIMARY OBJECTIVES:
I. To determine the relationship between urinary deuterated (\[D10\]) phenanthrene tetraol (PheT) level, PheT:phenanthrols (HOPhe) ratio, and the presence of bronchoepithelial metaplasia and/or dysplasia in smokers who have undergone screening bronchoscopy at Roswell Park Cancer Institute (RPCI).
OUTLINE:
Patients receive deuterated phenanthrene tetraol orally (PO). Urine samples are collected for laboratory studies for 6 hours after dosing.

- Primary Outcome Measures
Name Time Method Urinary deuterated phenanthrene tetraol level Up to 6 hours A multiple regression analysis will be performed including explanatory variables such as lesion status, presence/absence of chronic obstructive pulmonary disease (COPD) or asbestos, duration of smoking, smoking intensity, age, and gender.
PheT:HOPhe ratio Up to 6 hours A multiple regression analysis will be performed including explanatory variables such as lesion status, presence/absence of COPD or asbestos, duration of smoking, smoking intensity, age, and gender.
Correlation of deuterated phenanthrene tetraol level and PheT:HOPhe ratio with the presence of bronchoepithelial metaplasia and/or dysplasia Up to 6 hours A multiple regression analysis will be performed including explanatory variables such as lesion status, presence/absence of COPD or asbestos, duration of smoking, smoking intensity, age, and gender.
