Clinical Trial Summary

The purpose of the study is to obtain two year follow up data for subjects that received six vaccinations of NicVAX in prior phase III studies. No treatment will be administered. Anti-nicotine antibody levels and safety data will be collected.


Clinical Trial Description

This study will follow subjects that participated in the NicVAX phase III studies for a second year. These predecessor studies, Nabi-4514 (NCT#00836199) and Nabi-4515 (NCT#01102114) evaluate the efficacy and safety of 6 vaccinations of NicVAX or placebo as an aid to smoking cessation. The two phase III studies are one year in duration, and subjects who complete these studies are eligible to enroll in Nabi-4522. As the phase III studies are ongoing, subject assignment to NicVAX or placebo will remain masked. No intervention will be administered in Nabi-4522. Subjects will be followed for immunogenicity (anti-nicotine antibody level)and for safety. ;
