Smoking Cessation
Conditions
Brief summary
The primary objective of this trial is to assess the effects of cytisinicline at therapeutic and supratherapeutic doses on cardiac repolarization relative to placebo in healthy adult subjects who are smokers.
Interventions
compressed film-coated tablet containing 3 mg cytisinicline
Placebo tablets to match compressed film-coated tablet containing 3 mg cytisinicline
400 mg tablets

Study design
Masking description
Only the moxifloxacin treatment will not be blinded to site personnel and the participants, but moxifloxacin treatment will be blinded to the central cardiologist for assessments.
