Condition smoking
Treatment varenicline, nicotine patch and nicotine lozenge for 12 weeks
Phase phase 4
Sponsor University of Wisconsin, Madison
Start date February 2016
End date May 2016
Trial size 37 participants
Trial identifier NCT02681510, UW 2015-1376


This study will focus on enhancing future smoking cessation treatment effectiveness by piloting a potentially more powerful combination of three FDA-approved pharmacotherapies: varenicline plus combination of two types of nicotine replacement therapy (NRT) treatment (nicotine lozenge and nicotine patch). Data from this pilot study will help inform the design of future studies that would use this combination treatment as a cessation tool within the chronic care arsenal of treatments.

Additional Information

Official title UW-CTRI Smoking Cessation Medication Tolerability Study
Principal investigator Michael C Fiore
Description Recent research suggests that a new combination therapy may be especially effective in increasing long-term abstinence from smoking. A key purpose of the proposed study is to examine what types of tolerability concerns, if any, emerge from the simultaneous use of three FDA-approved cessation medications (varenicline, nicotine patch, and nicotine lozenge) and the timing of those events, in order to better assess how the use of this combination of tobacco cessation medicines can be most effectively and safely delivered and monitored. Study participants will take the three medications for 12 weeks in a manner consistent with labeling. Adverse events will be assessed at all study visits.
