Double-blind, Placebo-Controlled Pilot Study of Bupropion to Promote Smoking Cessation During Pregnancy

January 5, 2016 updated by: Angela Stotts, The University of Texas Health Science Center, Houston
This study is designed to gather preliminary effectiveness and safety data on the use of bupropion for smoking cessation in pregnant women attending a community prenatal clinic. This study will provide critical preliminary data in preparation for a larger, Phase III clinical trial.

Detailed Description

A randomized, double-blind, parallel group design will be used to allow a rigorous preliminary assessment of the feasibility, effectiveness, and safety of bupropion SR (sustained release; packaged as Zyban by GlaxoSmithKline) in promoting smoking cessation among women in their second and third trimester of pregnancy. Fifty pregnant smokers will be randomized to receive an 8-week course of either bupropion SR or matching placebo tablets. Both groups will receive evidence-based smoking cessation counseling. The primary smoking outcome will be 7-day point prevalence abstinence with cotinine validation at the end of the treatment. Secondary outcomes include enrollment, retention, and compliance rates; continuous abstinence from end of treatment through the 2 week followup; continuous abstinence from birth to 2nd week postpartum followup; self-reported reduction in number of cigarettes smoked per day; and maternal side effects and perinatal/neonatal outcomes. Preliminary smoking cessation and safety outcomes will be assessed for the generation of evidence-based hypotheses regarding clinical benefit of bupropion for pregnant smokers in preparation fo a larger trial.
