Description
Inclusion Criteria:
- Body mass index (BMI) 18 to 32 kg/m2;
- Forced expiratory volume in one second (FEV1) ≥80% of predicted for race, age, sex, and height;
- FEV1/FVC (forced vital capacity) ratio ≥70%;
- Smokers are defined as those currently smoking at least 10 cigarettes/day for at least 12 months with a positive urinary cotinine result and with no past (within 5 years) or present history of intrinsic lung disease (e.g. asthma, chronic obstructive pulmonary disease [COPD], chronic bronchitis, or other relevant conditions);
- Non-smokers are defined as those who never smoked or were exposed to less than 1 pack year within at least 12 months and with a negative urinary cotinine result.
Exclusion Criteria:
- Subject who is not surgically sterile or female subject who is less than 2 years postmenopausal, and who does not agree to use a highly effective birth control method during the study and up to 3 months after the last dose of investigational product;
- Any flu-like syndrome or other respiratory infections within 2 weeks prior to the Screening Visit;
- History of chronic obstructive pulmonary disorder (COPD) requiring intermittent or continuous use of any oral or inhaled medication therapy within last 3 years;
- Renal impairment as defined by a calculated creatinine clearance of ≤ 80 mL/minute;
- History of syncope within the last 6 months.

- Primary Purpose: Treatment
- Allocation: Non-Randomized
- Interventional Model: Parallel Assignment
- Masking: None (Open Label)
Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Adults who smoke
Day -1, subjects begin pre-treatment of oral dose regimen of carbidopa every 8 hours. Day 1, subjects receive a final dose of carbidopa and 1 hour later, a single dose of CVT-301. |
Levodopa inhalation powder, will be supplied in capsules containing levodopa (l-dopa), designed to deliver to the lung using the CVT-301 inhaler.
Administered orally according to the carbidopa dosing schedule.
