About the trial

What the trial wants to find out

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.

The 7 groups in the trial

  • Group I (varenicline, counseling)Treatment being tested

    Participants receive varenicline PO daily or BID for 6 weeks in the absence of unacceptable toxicity. Participants who quit smoking continue treatment for 6 additional weeks in the absence of unacceptable toxicity. Participants also receive behavioral smoking cessation counseling.

    Treatment: Questionnaire Administration, Tobacco Cessation Counseling, and Varenicline

  • Group II (NRT, counseling)Treatment being tested

    Participants receive NRT consisting of a patch, lozenges, or gum daily for 6 weeks in the absence of unacceptable toxicity. Participants who quit smoking continue treatment for 6 additional weeks in the absence of unacceptable toxicity. Participants also receive behavioral smoking cessation counseling.

    Treatment: Nicotine Replacement, Questionnaire Administration, and Tobacco Cessation Counseling

  • Group III (varenicline or NRT, counseling)Treatment being tested
