Clinical Trial Summary

PEP03 is a new chemical entity developed as a highly selective, potent, and orally active 5-LO inhibitor. PEP03 exerts its action by blocking the generation of both cysteinyl LTs and LTB4. These LTs have been associated with the inflammatory response in the lung and with the clinical sequelae, including bronchospasm. Preclinical pharmacological in- vitro, ex-vivo and in-vivo testing indicates that PEP03 has multiple beneficial actions including prevention of bronchoconstriction, and reduction of vascular leakage, cellular infiltration, and bronchial hyperresponsiveness.

Clinical studies in asthmatic patients indicate that PEP03 improved FEV1 and other secondary endpoints, such as morning and evening peak flow, daytime and nighttime symptoms score, beta-agonist use, physician’s and patient’s global impression of change. Since leukotrienes have been suggested to be involved in the pathophysiology of COPD, this study is designed to explore the clinical utility of PEP03 for the treatment of moderate COPD.6; 7; 8; 9

Eligibility

Inclusion Criteria:

3. Subjects must have at least one episode of COPD-related symptoms (e.g. cough, sputum production, shortness of breath) within 2 months prior to screening.

4. Subjects must have a < 12% increase in FEV1 after a fixed dose of bronchodilator (200 ?g inhaled salbutamol).

5. Subjects have a history of > 10 pack years of smoking (1 pack year = 20 cigarettes smoked per day for 1 year or equivalent).

6. Subjects of childbearing potential must use adequate birth control measures and must have a negative serum pregnancy test prior to study entry.

7. Subjects have to be able to adhere to the study visit schedule and other protocol requirements.

8. Subjects must have the ability to use peak flow meter correctly and record patient diary cards 9. Subjects must provide signed, written informed consent prior to participation in the study.

Exclusion Criteria:

• 1. Subjects have asthma, allergic rhinitis or atopy as main component of their obstructive airway disease.

2. Subjects are being treated with long term oxygen therapy, requiring supplemental oxygen more often than on an occasional/as need basis or requiring nocturnal positive pressure for sleep apnea.

3. Subjects have a history of severe right sided heart failure or cor pulmonale.

4. Subjects have had a serious infection (e.g. hepatitis, pneumonia or pyelonephritis) within the previous 3 months.

5. Subjects have airway obstruction due to diseases with known etiology or specific pathology, such as cystic fibrosis, or bronchiectasis.

6. Subjects with lung cancer, sarcoidosis, tuberculosis, or lung fibrosis. 7. Subjects with a history of drug or alcohol abuse. 8. Subjects have used investigational drugs within 1 month prior to screening or within 5 half-lives of the investigational agent, whichever is longer.

9. Subjects are currently treated with cromolyn sodium or nedocromil, long-acting theophylline, leukotriene modifiers, oral or inhaled corticosteroids, long acting ß2-agonists, or long-acting anticholinergics.

10. Subjects with liver enzymes (AST, ALT, bilirubin) > 3 X upper limit of normal range.
