Two-Part Study to Evaluate the Dose Response of SCH 527123 on Sputum Neutrophilia Following Ozone Challenge in Healthy Subjects and Chronic Obstructive Pulmonary Disease (COPD) Patients (P05567 AM7)

Randomized, Double-Blind, Multiple-Dose, Placebo-Controlled, Incomplete Crossover, Two-Part Study to Evaluate the Dose Response of SCH 527123 on Sputum Neutrophilia Following Ozone Challenge in Healthy Subjects and COPD Patients

Trial to evaluate the dose response of SCH 527123 in reducing inflammation from an ozone-induced sputum neutrophilia in both healthy subjects and subjects with COPD.

• Subject must be free of any clinically significant disease that would interfere with the study evaluations (also Part 2).
• Screening ECG conduction intervals must be within gender specific normal range; QTcB males ≤430 msec and females ≤450 msec (also Part 2).
• Vital sign measurements must be: a) oral body temperature, between 35.0°C and 37.5°C; b) systolic blood pressure, 90 to 140 mm Hg (160 mm Hg, Part 2); c) diastolic blood pressure, 45 to 90 mm Hg (100 mm Hg, Part 2); d) pulse rate, 40 to 100 bpm.
• Subject and partner(s) must be using an accepted method of contraception during the trial through 2 months post-treatment (also Part 2).
• Prior to randomization, subject must be a responder to ozone (also Part 2).

Part 2

• Subject with a diagnosis of COPD for at least 1 year and FEV1 ≥65% of predicted value post bronchodilation (measurement 30 minutes after 400 mcg salbutamol administration) and FEV1/FVC of <70%.
• Subject of either sex and of any race between the age of 40 and 65 years, with a BMI between 19 and 32.
• Subject must be active or exsmoker (cigarettes, cigars and/or pipes).
• Subject must have a normal exercise stress test (no clinically significant ECG findings).

Exclusion Criteria:

Part 1 and Part 2

• Subject with a history of alcohol or drug abuse in the past 2 years.

• Subject who has donated blood in the past 60 days.

• Subject who has demonstrated allergic reactions (eg, food, drug, atopic reactions or asthmatic episodes) which may interfere with ability to participate in the trial.
