Dose Escalating Study of CCI15106 Inhalation Capsules in Healthy Subjects and Moderate Chronic Obstructive Pulmonary Disease (COPD) Patients

A Double-blind (Sponsor Unblind), Randomized, Placebo-controlled, Single and Repeat Escalating Dose Study to Investigate the Safety, Tolerability, and Pharmacokinetics of CCI15106 Capsules for Inhalation in Healthy Subjects and Patients With Moderate Chronic Obstructive Pulmonary Disease (COPD)

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.

This will be a three-part study. Part 1 will investigate single ascending doses and Part 2 repeat ascending doses in healthy subjects. In Part 3, a single dose will be administered to patients with moderate COPD.

There will be screening period of up to 30 days. The treatment period will be 3 days for Parts 1 and 3 and 16 days for Part 2. Follow-up will be performed within 30 days after the last dose.
