Trial Outcomes & Findings for A Study to Evaluate the Effect of Lorcaserin Hydrochloride on Smoking Cessation (NCT NCT02044874)

NCT ID: NCT02044874

Last Updated: 2019-04-16

Results Overview

Primary efficacy was assessed as the CO (carbon monoxide)-confirmed continuous abstinence rate for the last 4 weeks of treatment (Month 3: Weeks 9 through 12), defined as no reported smoking (not even a puff) or other nicotine use, verified by end expiratory CO levels \<= 10 ppm.
