 when administered for either 6 or 12 weeks, compared to placebo. All subjects received standard behavioral support and were assigned to one of the following groups:

•Arm A: 12 weeks of placebo 

•Arm B: 6 weeks of cytisinicline, followed by 6 weeks of placebo 

•Arm C: 12 weeks of cytisinicline

The ORCA-2 study had two independent primary endpoints that evaluated for successful smoking cessation for both 6-week and 12-week durations of cytisinicline treatment, compared to placebo. The primary endpoints for ORCA-2 were biochemically verified continuous smoking cessation measured during the last 4 weeks of each treatment duration. Both the 6- and 12-week cytisinicline treatments demonstrated significantly better quit rates than placebo with ORs of 8.0 and 6.3, respectively. 

•Subjects who received 12 weeks of cytisinicline treatment had 6.3 times higher odds, or likelihood, to have quit smoking during the last 4 weeks of treatment compared to subjects who received placebo (p<0.0001). The abstinence rate during weeks 9-12 was 32.6% for cytisinicline compared to 7.0% for placebo.

•Subjects who received 6 weeks of cytisinicline treatment had 8.0 times higher odds, or likelihood, to have quit smoking during the last 4 weeks of treatment compared to subjects who received placebo (p<0.0001). The abstinence rate during weeks 3-6 was 25.3% for cytisinicline compared to 4.4% for placebo. 

The secondary endpoints measured continuous smoking abstinence after treatment out to 24 weeks. Both the 6- and 12-week secondary endpoints for continuous abstinence demonstrated significantly better quit rates for cytisinicline treated subjects than placebo. The continuous abstinence rate from week 9 to 24 was 21.1% for the 12-week cytisinicline arm compared to 4.8% for placebo, with an OR of 5.3 (p<0.0001). The continuous abstinence rate from week 3 to 24 was 8.9% for the 6-week cytisinicline arm compared to 2.6% for placebo, with an OR of 3.7 (p=0.0016).

A third secondary endpoint compared the two cytisinicline treatment arms and
