This study will be the first administration of CCI15106 capsules for inhalation to humans. The primary objective of the study is to investigate the safety and tolerability of single and repeat escalating doses of CCI15106 in healthy subjects and patients with moderate chronic obstructive pulmonary disease (COPD). The intention of this study is to provide sufficient confidence in the safety of the molecule delivered by inhalation to inform progression to further repeat dose and proof of concept studies.
