Title: Phase 2, Randomized, Double-Blind, Placebo-Controlled, Study to Evaluate the Safety, Tolerability and Efficacy of MP-376 Inhalation Solution Administered for 5 Days Every 28 Days to Prevent Acute Exacerbations in High Risk COPD Patients
Brief Summary: Patients with Chronic Obstructive Pulmonary Disease (COPD) suffer from frequent and recurrent acute exacerbations (AECB) which are associated with enormous healthcare expenditures and significant morbidity, specifically an increased risk of death, a decline in pulmonary function and a significant change in quality of life. Bacteria appear to have an important role in acute exacerbations in chronic bronchitis and COPD. Studies of acute exacerbations in COPD have shown a reduction in bacterial load with prolonged exacerbation-free interval. In addition, recent studies indicate that acquisition of a new strain of H. influenzae, M. catarrhalis, S. pneumoniae or P. aeruginosa are responsible for many of these exacerbations. Chronic inflammation and bacterial infection predispose many patients to frequent and recurrent acute exacerbations.

Mpex believes that intermittent administration of inhaled MP-376 in high risk patients will decrease the incidence of acute exacerbations by both by lowering the organism burden, and resultant inflammation, as well as pre-emptive eradication of any newly acquired bacterial strains.


Options:
A: Inclusion Criteria:

* Giving written informed consent
* History of COPD (according to GOLD 2009) for at least 12 months prior to baseline Visit V0 associated with chronic productive cough for 3 months in each of the 2 years prior to baseline visit (with other causes of productive cough excluded)
* Age ≥ 40 years

Up to 3 months before baseline Visit V0 free or fixed combinations of LABA and ICS are allowed, including changes in dose, active substances, and brands. In the last 3 months before baseline Visit V0 patients must be pre-treated with fixed combinations of LABA and ICS at a constant dose (maximum approved dosage strength of the combination).

B: Inclusion Criteria:

1. All patients must have a diagnosis of chronic obstructive pulmonary disease (COPD) and must meet the following criteria at Visit 1:

   Patients must have relatively stable, moderate to very severe airway obstruction with a post-bronchodilator FEV1 \<=70% of predicted normal and FEV1 \<=70% of FVC post-bronchodilator (i.e. 30 minutes after inhalation of 4 puffs of 100 µg salbutamol or equivalent SABA). Predicted normal values will be calculated according to ECSC.

   For Height measured in inches Males: FEV1 predicted (L) = 4.30 x (height (inches) / 39.37)-0.029 x age (yrs) - 2.49 Females:FEV1 predicted (L) = 3.95 x (height (inches) / 39.37)-0.025 x age (yrs) - 2.60 For Height measured in metres Males: FEV1 predicted (L) = 4.30 x (height (metres)) - 0.029 x age (years) - 2.49 Females: FEV1 predicted (L) = 3.95 x (height (metres)) - 0.025 x age (years) - 2.60
2. All patients must sign an informed consent consistent with ICH-GCP guidelines prior to participation in the trial.
3. Male or female patients 40 years of age or older.
4. Patients with a history of at least one exacerbation within the past year requiring treatment with either antibiotics and/or systemic steroids and/or hospitalisation.
5. Patients must be current or ex-smokers with a smoking history of \>= 10 pack-years. (Patients who have never smoked cigarettes must be excluded.)
6. Patients must be able to perform all study-related procedures including technically acceptable pulmonary function tests (PFTs).
7. Patients must be able to inhale medication in a competent manner from the HandiHaler and a metered dose inhaler (MDI).
8. Patients must be able to maintain records (patient daily diary card) during the study period as required in the protocol.

Exclusion Criteria:

1. Significant diseases other than COPD. A significant disease is defined as a disease or condition which, in the opinion of the investigator, may put the patient at risk because of participation in the study or may influence either the results of the study or the patients' ability to participate in the study.
2. Patients with a diagnosis of asthma.
3. Patients with a life-threatening pulmonary obstruction, or a history of cystic fibrosis.
4. Patients with known active tuberculosis.
