lung deposition of beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide administered via pmdi in healthy, asthmatic and copd patients

Conditions: Chronic Obstructive Pulmonary Disease; Asthma

Summary: the purpose of this study is to investigate the lung deposition and distribution pattern of beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide using a gamma-scintigraphic technique after inhalation of a single dose of 99mtc radiolabelled chf 5993 administered via pmdi in healthy volunteers, asthmatic and copd patients.

4. any clinically relevant abnormal laboratory value at screening suggesting an unknown disease and requiring further clinical investigation or which may impact the safety of the subject or the evaluation of the result of the study according to the investigator's judgment 5. clinically relevant and uncontrolled hepatic, gastrointestinal, renal, genitourinary, endocrine, metabolic neurologic, or psychiatric disorder that may interfere with successful completion of this protocol 6. serology at the screening positive to hiv1 or hiv2 and positive results for hepatitis which indicates acute or chronic hepatitis b (i.e. positive hb surface antigen hbsag positive and/or positive hb core antibody anti-hbc) or hepatitis c (hcv antibody); 7. subjects with history of sustained and non-sustained cardiac arrhythmias (ecg demonstrated) and subjects with a family history of sudden cardiac death 8. subjects who have cardiovascular condition such as, but not limited to unstable ischemic heart disease, nyha class iii/iv left ventricular failure, acute ischemic heart disease in the last year prior to study screening, which may impact the safety of the subject or the evaluation of the result of the study according to the investigator's judgment 9. medical diagnosis of narrow-angle glaucoma, prostatic hypertrophy or bladder neck obstruction that in the opinion of the investigator would prevent use of anticholinergic agents" 10. significant blood loss ≥ 400 ml within 3 months prior screening and between screening and day 1; 11. participation in another clinical trial with an investigational drug in the previous 3 months before the administration of the study drug; a longer and more appropriate time could be considered by the principal investigator based on the elimination of the half-life and/or long term toxicity of the previous investigational drug;
