NCT01400815
A randomized, active controlled clinical trial in which a total of 216 healthy smokers will be enrolled and followed over approximately 19 weeks. The trial will evaluate the efficacy and safety of using X-22 as a smoking cessation aid. Healthy smokers who plan to quit smoking will be screened for eligibility. Subjects will be randomized in a 1:1 ratio to 1 of the 2 treatment arms: * Group 1: X-22 Cigarettes (very low nicotine) * Group 2: Active Control Cigarettes The randomization will be stratified by gender. Efficacy will be assessed by analysis of cigarette consumption using self-report diaries and measurement of exhaled carbon monoxide (CO) and cotinine concentrations. Safety will be assessed by evaluation of adverse events, physical examinations, clinical laboratory tests, and measurement of heart rate, blood pressure, and body weight at each study visit.
NCT03548935
This study will look at the change in participants' body weight from the start to the end of the study. The weight loss in participants taking semaglutide (a new medicine) will be compared to the weight loss of participants taking "dummy" medicine. In addition to taking the medicine, participants will have talks with study staff about healthy food choices, how to be more physically active and what you can do to lose weight. Participants will either get semaglutide or "dummy" medicine - which treatment participants get, is decided by chance. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The study has two phases: A main phase and an extension phase.The main phase will last for about 1.5 years. Participants will have 15 clinic visits and 10 phone calls with the study doctor. Extension phase: Approximately 300 participants will continue in the extension phase in the following countries only: Canada, Germany, the UK and selected sites in the US and Japan. These participants will be in the study for about 2.5 years.They will not receive treatment, but will attend another 5 follow-up visits with the study doctor.
