Arm Intervention/treatment
Placebo Comparator: Placebo + Behavioral Support
one placebo tablet orally (PO) three times daily (TID) plus behavioral support for 12 weeks
Drug: Placebo
film-coated oral tablets containing matched placebo

Behavioral: Behavioral support
Behavioral support sessions by a qualified study site staff member will be participant-driven and will include direct engagement with the subject about their attempt to quit smoking. Each session will last approximately 10 minutes.

Experimental: Cytisinicline + Placebo + Behavioral Support
one cytisinicline tablet PO TID plus behavioral support for 6 weeks followed by one placebo tablet PO TID plus behavioral support for 6 weeks
Drug: Cytisinicline
film-coated oral tablets containing 3 mg cytisinicline
Other Name: Cytisine

Drug: Placebo
film-coated oral tablets containing matched placebo

Behavioral: Behavioral support
Behavioral support sessions by a qualified study site staff member will be participant-driven and will include direct engagement with the subject about their attempt to quit smoking. Each session will last approximately 10 minutes.

Experimental: Cytisinicline + Behavioral Support
one cytisinicline tablet PO TID plus behavioral support for 12 weeks
Drug: Cytisinicline
film-coated oral tablets containing 3 mg cytisinicline
Other Name: Cytisine

Behavioral: Behavioral support
Behavioral support sessions by a qualified study site staff member will be participant-driven and will include direct engagement with the subject about their attempt to quit smoking. Each session will last approximately 10 minutes.




Primary Outcome Measures :
  1. Proportion of participants with smoking abstinence during the last 4 weeks of 6 weeks cytisinicline treatment versus placebo treatment (Wk 3-6) [ Time Frame: Week 3-6 ]
    Smoking abstinence as verified by weekly expired carbon monoxide (CO) measurements ≤10 parts per million (ppm).

  2. Proportion of participants with smoking abstinence during the last 4 weeks of 12 weeks cytisinicline treatment versus placebo treatment (Wk 9-12) [ Time Frame: Week 9-12 ]
    Smoking abstinence as verified by weekly expired carbon monoxide (CO) measurements ≤10 parts per million (ppm).


Secondary Outcome Measures :
  1. Proportion of participants with continuous smoking abstinence to Week 24 [ Time Frame: Week 24 ]
    Smoking abstinence as verified by monthly expired CO measurements ≤10 ppm.

  2. Proportion of Participants Who are Relapse-Free at Week 24 [ Time Frame: Week 24 ]
    Relapse is defined as participant reported resuming smoking or an expired CO measure ≥ 10ppm
