Patient description: A 10 year old child is brought to the emergency room complaining of myalgia, cough, and shortness of breath. Two weeks ago the patient was seen by his pediatrician for low-grade fever, abdominal pain, and diarrhea, diagnosed with a viral illness, and prescribed OTC medications. Three weeks ago the family returned home after a stay with relatives on a farm that raises domestic pigs for consumption. Vital signs: T: 39.5 C, BP: 90/60 HR: 120/min RR: 40/min. Physical exam findings include cyanosis, slight stiffness of the neck, and marked periorbital edema. Lab results include WBC 25,000, with 25% Eosinophils, and an unremarkable urinalysis.

Clinical trial eligibility criteria: eligible ages (years): 40.0-999.0,  Pulmonary Disease, Chronic Obstructive Informed Consent: A signed and dated written informed consent prior to study participation Type of subject: Outpatient Age: Subjects 40 years of age or older at Visit 1 Gender: Male or female subjects. A female is eligible to enter and participate in the study if she is of: Non-child bearing potential (i.e. physiologically incapable of becoming pregnant, including any female who is post-menopausal or surgically sterile). Surgically sterile females are defined as those with a documented hysterectomy and/or bilateral oophorectomy or tubal ligation. Post-menopausal females are defined as being amenorrhoeic for greater than 1 year with an appropriate clinical profile, e.g. age appropriate, > 45 years, in the absence of hormone replacement therapy OR Child bearing potential, has a negative pregnancy test at screening, and agrees to one of the following acceptable contraceptive methods used consistently and correctly (i.e. in accordance with the approved product label and the instructions of the physician for the duration of the study screening to safety follow-up contact): Abstinence; Oral Contraceptive, either combined or progestogen alone; Injectable progestogen; Implants of levonorgestrel; Estrogenic vaginal ring; Percutaneous contraceptive patches; Intrauterine device (IUD) or intrauterine system (IUS); Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject. For this definition, "documented" refers to the outcome of the investigator's/designee's medical examination of the subject or review of the subject's medical history for study as obtained via a verbal interview with the subject or from the subject's medical records. Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository) COPD Diagnosis: An established clinical history of COPD in accordance with the definition by the American Thoracic Society/European Respiratory Society Smoking History: Current or former cigarette smokers with a history of cigarette smoking of >=10 pack-years at screening (visit 1) [number of pack years = (number of cigarettes per day / 20) x number of years smoked (e.g., 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years)]. Previous smokers are defined as those who have stopped smoking for at least 6 months prior to Visit 1. Note: Pipe and/or cigar use cannot be used to calculate pack-year history Severity of COPD symptoms: A score of >=10 on the COPD Assessment Test (CAT) at screening Severity of COPD Disease: A post-albuterol/salbutamol FEV1/ Forced Vital Capacity (FVC) ratio of <0.70 at Screening Existing COPD maintenance treatment: Subject must be receiving daily maintenance treatment for their COPD for at least 3 months prior to Screening. Note: Subjects receiving only Pro re nata (PRN) COPD medications are not eligible  Pregnancy: Women who are pregnant or lactating or are planning on becoming pregnant during the study Asthma: Subjects with a current diagnosis of asthma. (Subjects with a prior history of asthma are eligible if they have a current diagnosis of COPD) Alpha1-antitrypsin deficiency: Subjects with Alpha1-antitrypsin deficiency as the underlying cause of COPD Other respiratory disorders: Subjects with active tuberculosis, lung cancer, significant bronchiectasis, sarcoidosis, lung fibrosis, pulmonary hypertension, interstitial lung diseases or other active pulmonary diseases Lung resection: Subjects with lung volume reduction surgery within the 12 months prior to Screening Risk Factors for Pneumonia: immune suppression (e.g. human immunodeficiency virus [HIV], Lupus) or other risk factors for pneumonia (e.g. neurological disorders affecting control of the upper airway, such as Parkinson's Disease, Myasthenia Gravis). Patients at potentially high risk (e.g. very low BMI, severely malnourished, or very low FEV1) will only be included at the discretion of the Investigator Pneumonia and/or moderate or severe COPD exacerbation that has not resolved at least 14 days prior to Screening and at least 30 days following the last dose of oral/systemic corticosteroids (if applicable). In addition, any subject that experiences pneumonia and/or moderate or severe COPD exacerbation during the run-in period will be excluded Other Respiratory tract infections that have not resolved at least 7 days prior to screening Abnormal Chest x-ray(CXR): Chest x-ray (posteroanterior and lateral) reveals evidence of pneumonia or a clinically significant abnormality not believed to be due to the presence of COPD, or another condition that would hinder the ability to detect an infiltrate on CXR (e.g. significant cardiomegaly, pleural effusion or scarring). All subjects will have a chest x-ray at Screening Visit 1 (or historical radiograph or computerised tomography (CT) scan obtained within 3 months prior to screening) that will be over-read by a central vendor. Note: Subjects who have experienced pneumonia and/or moderate or severe COPD exacerbation within 3 months of screening must provide a post pneumonia/exacerbation chest x-ray to be over-read by the central vendor or have a chest x-ray conducted at screening. For sites in Germany: If a chest x-ray (or CT scan) within 3 months prior to Screening (Visit 1) is not available, approval to conduct a diagnostic chest x-ray will need to be obtained from the Federal Office for Radiation Protection (Bundesamt für Strahlenschutz [BfS]) Other diseases/abnormalities: Subjects with historical or current evidence of clinically significant cardiovascular, neurological, psychiatric, renal, hepatic, immunological, gastrointestinal, urogenital, nervous system, musculoskeletal, skin, sensory, endocrine (including uncontrolled diabetes or thyroid disease) or hematological abnormalities that are uncontrolled. Significant is defined as any disease that, in the opinion of the Investigator, would put the safety of the subject at risk through participation, or which would affect the efficacy or safety analysis if the disease/condition exacerbated during the study
