Brief Summary

The primary objectives of this study are:

• Estimated glomerular filtration rate (eGFR) ≥90 mL/min at Screening, determined by the Cockcroft-Gault equation.
• No clinically relevant abnormalities on clinical laboratory tests at Screening.
• Blood pressure and pulse rate at Screening within the following ranges:

• SBP 90-140 mmHg, DBP 60-90 mmHg, and pulse rate 60-100 bpm (inclusive) for subjects <65 years of age.
• SBP 95-160mmHg, DBP 65-95 mmHg, and pulse rate 60-100 bpm (inclusive) for subjects ≥65 years of age.

Exclusion Criteria

• Known hypersensitivity/allergy reaction to cytisinicline substance or any of the excipients.
• History of renal, heart, and/or liver transplant.
• History or clinical evidence of any disease and/or existence of any surgical or medical condition, which might interfere in a relevant manner with the absorption, distribution, metabolism, or excretion of the study treatment except for renal disease.
• Symptoms of an acute clinically relevant infection in the 4-week period preceding Screening (e.g., bacterial, viral, or fungal infection).
• History or clinical evidence of alcohol use disorder or substance use disorder according to Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) classification, within the 3-year period prior to Screening.
