Trial Information

Pioglitazone for Lung Cancer Chemoprevention

This trial evaluates the oral PPAR gamma agonist pioglitazone in a double-blind placebo
controlled trial. The high risk current and former smokers qualify based on tobacco
exposure, airflow limitation on lung function testing, and sputum cytologic atypia.
Subjects have a quantitative high resolution thoracic CT scan and a fluorescent bronchoscopy
at study entry and after 6 months on drug or placebo. Biologic samples are collected at both
time points. The primary outcome is endobronchial histology and determining if pioglitazone
can retard progression. Secondary endpoints related to the PPAR gamma signaling pathway
will also be analyzed.

Inclusion Criteria:

- Current or former smoker (at least 10 pack years);

- One or more of the following:

- Mild or worse sputum atypia

- Airflow Limitation (FEV1/FVC<70% predicted)

- Biopsy proven airway dysplasia

Exclusion Criteria:

- MI with ejection fraction < 50%;

- severe/unstable angina;

- history of coronary or peripheral arterial bypass grafting;

- NYHA class III or IV congestive heart failure;

- hypoxemia (less than POX 90 with supplemental oxygen); Diabetes type I or II; severe
COPD (GOLD stage III or IV); clinically significant edema requiring diuretic therapy;

- life expectancy < 6 months; history of bladder cancer

- pregnant or breast feeding; inability to give informed consent
