Varenicline For Nicotine Vaping Cessation In Non Smoker Vaper Adolescents

Status Terminated

Clinical Trial Summary

The Investigators propose a randomized, placebo-controlled trial to test the hypothesis that varenicline added to group behavioral and texting support will be well tolerated and improve vaping cessation rates among nicotine dependent adolescents who vape, do not smoke regularly, and are willing to try treatment to stop vaping compared to placebo added to group behavioral and texting support. The study will consist of a three-arm randomized, placebo-controlled, parallel-group study of (1) varenicline up to 1 mg bid for 12 weeks added to behavioral and texting support compared with (2) behavioral and texting support and placebo and (3) monitoring only. The primary comparison will be of vaping cessation rates in those assigned to varenicline vs placebo.To do this, the investigators propose to enroll 300 adolescents aged 16-25 who meet eligibility criteria.

Clinical Trial Description

Enrollees will include 300 nicotine dependent adolescents aged 16-25, who vape, do not smoke, and want to quit vaping. The study will will consist of a three-arm randomized, placebo-controlled, parallel-group study of (1) varenicline up to 1 mg bid for 12 weeks added to behavioral and texting support for adolescent vaping cessation or (2) behavioral and texting support and placebo or (3) monitoring only. The primary comparison of interest is efficacy of (1) varenicline vs (2) placebo arms on vaping abstinence outcomes. The study consists of one enrollment visit, one baseline visit, twelve weekly individual treatment and assessment sessions, and six monthly visits at weeks 4, 8, 12, 16, 20 and 24 weeks. At the enrollment visit, participants will complete interviews, questionnaires and diagnostic assessments, as well as saliva and urine sample and vitals. At the baseline visit, participants will complete several interviews, questionnaires, provide a saliva sample for cotinine measurement, and be randomized to the varenicline plus behavioral treatment group, the placebo plus behavioral treatment group, or monitoring-only group. Study staff will distribute varenicline or identically appearing placebo with instructions on how to take the study medication at weeks 0, 2, 4 and 8. Participants will be instructed to bring all empty and unused study medication at each in-person study visit through Week 12. At the weekly treatment meetings, participants will participate in cognitive behavioral therapy and complete questionnaires. Monthly visits will consist of interviews, questionnaires and a saliva and urine sample. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
