Clinical Details

Official title: Safety and Tolerability of Varenicline When Used for Smoking Cessation/Reduction in Individuals With Severe and Persistent Mental Illness: An Open Label Pilot Trial

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Changes in the symptoms of the primary illness. These outcomes will be measured at study visits 1, 2, 4, 8, and 12.

Secondary outcome: Safety and tolerability, nicotine dependence, and smoking cessation/reduction. These outcomes will be measured at study visits 1-12.

Detailed description: Researchers are looking to recruit a total of 50 subjects at Riverview and Forensic Psychiatric Hospitals who would like to reduce or quit smoking cigarettes. This open label pilot study will gather information regarding the safety and tolerability of varenicline in subjects who have been diagnosed with schizophrenia or schizoaffective disorder. Consenting subjects will be prescribed varenicline as follows: varenicline 0. 5 mg/d for days 1 to 3, 0. 5 mg twice daily for days 4 to 7, then 1 mg twice daily through week 12. The research team will meet with the subject once a week for twelve weeks and the subject will be interviewed and asked to complete questionnaires about his/her psychiatric symptoms, tobacco use and nicotine dependence. The measures used include the FTND, PANSS, CGI-I, CGI-S, ESRS, UKU, BARS, WSWS, QSU-brief, mCEQ, and the OAS-M. The CGI-SS will also be completed throughout the study as well as once weekly for three weeks following the completion of the study (Post-Study follow-up visits 1-3).
