Study of Safety and Drug Levels of CCI15106 Inhalation Powder in Healthy Adults and Adults With Moderate Chronic Obstructive Pulmonary Disease. Study of CCI15106 Levels in People Standing Near the Person Inhaling the Drug

A Double-blind (Sponsor Unblind), Randomized, Placebo-controlled, Single and Repeat Escalating Dose Study to Investigate the Safety, Tolerability, and Pharmacokinetics of CCI15106 Inhalation Powder in Healthy Participants and Participants With Moderate Chronic Obstructive Pulmonary Disease (COPD) Including Evaluation of Environmental and Healthy By-stander Exposure Levels During Dosing

This single and repeat increasing dose study will collect information on safety, tolerability and drug levels in the body of the CCI15106 inhalation powder. The study will also look at the level of CCI15106 that will be released into the air and may be found in the blood of the people standing around the person inhaling it (bystanders). This is a two-part study in which Part 1 will enroll healthy subjects and look at environmental and bystander exposure and Part 2 will enroll subjects with moderate COPD. Approximately 36 healthy subjects and approximately 22 subjects with COPD will be randomized in this study for dosing. The total study duration will be 82 days for Cohort A Part 1; 75 days for Cohort B Part 1 and Cohort C Part 1; 77 days for Cohort A Part 2; and 90 days for Cohort B Part 2.

Some important Inclusion Criteria:

• Women who are not pregnant or breastfeeding, and not of childbearing potential.

For subjects with COPD:

• 40 to 75 years of age.
• Diagnosed with moderate COPD by a doctor.
• Have breathing test results that are consistent with moderate COPD as defined in the study protocol.
• A smoker or an ex-smoker.
• Men who agree to use contraception during the treatment period and for at least 7 months after the last dose of study medicine and agree not to donate sperm during this period.
• Women who are not pregnant or breastfeeding, and not of childbearing potential.

Some Important Exclusion Criteria:

For healthy subjects and bystanders:

• History of liver disease.
• Use of over-the-counter or prescription drugs (including vitamins) 7 days before the study until completion of the follow-up visit.
• Participation in the study would result in loss of more than 500 milliliter (mL) of blood within 3 months.
• Participation in another clinical trial with an investigational product within about 3 months before this study.
• Positive drug/alcohol screen.
• Regular use of known drugs of abuse.
• Regular alcohol consumption within 3 months before the study.
• Breath test indicative of smoking at study start.
• Documented lactose allergy/intolerance.
• Men whose partner is pregnant or breastfeeding cannot participate.
• Certain blood test results may not allow subjects to participate, as described in the study protocol.

For subjects with COPD:

• History of liver disease.
• Poorly controlled COPD disease as, for example, more than 2 exacerbations of COPD per year.
• Some respiratory conditions, like for example active tuberculosis, lung cancer or any other respiratory condition. Subjects with other respiratory conditions (for example, clinically significant: asthma, pulmonary fibrosis, bronchiectasis) are excluded if these conditions are the primary cause of their respiratory symptoms.
• Unstable or uncontrolled cardiac disease.
• Problems with kidney function as defined in the study protocol.
• Past or current medical conditions or diseases that are not well controlled.
• Subjects are not allowed to take oral corticosteroids from 4 weeks prior to screening and for the duration of the study.
• Subjects taking medications for any chronic conditions have to be on stable doses for 4 weeks before screening and until after study treatment is finished.
• Use of short-acting inhaled bronchodilators is allowed, but subjects must be able to stop their medications several times during the study.
• Use of long-acting bronchodilators is allowed, but subjects must be able to change the schedule of their medications twice during the study.
• Participation in the study would result in loss of more than 500 mL within 3 months.
• Participation in another clinical trial with an investigational product within about 3 months before this study.
• Positive drug/alcohol screen.
• Regular use of known drugs of abuse.
• Regular alcohol consumption within 3 months before the study.
• Unable to refrain from smoking for certain periods during the study (maximum about 6 hours).
• Documented lactose allergy/intolerance.
• Men whose partner is pregnant or breastfeeding cannot participate.
• Certain blood test results may not allow subjects to participate, as described in the study protocol.
