Achieve Life Sciences announces final data from cytisinicline study
Achieve Life Sciences (ACHV) announced final data from their Phase I/II multi-dose, pharmacokinetic and pharmacodynamics, or PK/PD, clinical study of cytisinicline in smokers.
The study evaluated the repeat-dose PK and PD effects of 1.5 mg and 3 mg cytisinicline in 26 healthy volunteer smokers when administered over the standard 25-day course of treatment.
Smokers in the study had a mean age of 39 years, smoked on average 17.2 cigarettes a day, and were not required to quit smoking or have a predetermined quit date while on study.
All subjects had a significant and immediate reduction in cigarettes smoked within 2 days of initiating cytisinicline treatment.
By Day 26, subjects had an average 80% reduction in cigarettes smoked, 82% reduction in expired carbon monoxide, and 46% had stopped smoking.
The biochemically verified smoking cessation rates were 39% and 54% in the 1.5 mg and 3.0 mg cytisinicline treated groups, respectively.
The PK results indicated expected increases in plasma concentration between the standard 1.5 mg and higher 3.0 mg doses of cytisinicline with no evidence of drug accumulation.
Cytisinicline at either dose was well tolerated with only transient, mild-to-moderate headache as the most common adverse event, which was not treatment limiting. No adverse events were severe, serious, or led to withdrawal from the study.
Cindy Jacobs, CMO at Achieve commented, “Given the short 25-day treatment period, the abstinence rates observed are impressive, particularly since subjects were not required to commit to quitting and received minimal behavioral support during the study. These results continue to support our belief that cytisinicline could be a well-tolerated and effective potential treatment option for the millions of people who are battling nicotine addiction.”
ACHV closed at $1.81, it last traded at $2.88.
