What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 4 studies follow an already-approved treatment in real-world conditions to monitor long-term safety and effectiveness.

This trial targets 2,010 participants in total. It began in 2020-08-04 with a primary completion date of 2028-12-31.

Brief Summary

This phase IV trial investigates how to personalize treatments (such as medications and/or counseling) for quitting smoking based on the unique character traits of participants. Nicotine replacement therapy, counseling, and/or drugs such as varenicline and bupropion may help participants quit smoking or change smoking behavior. This trial may also help doctors individualize smoking cessation treatment for participants who do not quit smoking after the first course of treatment.
