Biomarker Feedback to Motivate Cessation in Pregnancy

Status Completed

Clinical Trial Summary

Phase 3 Pilot Clinical Trial.

Clinical Trial Description

Developing effective tobacco cessation interventions during pregnancy for American Indian and Alaska Native people is a national priority and will contribute to the U.S. public health objective of reducing tobacco-related cancer health disparities. The proposed project builds on the investigators' successful partnership with the Alaska Native community and previous work with Alaska Native pregnant women. The investigators propose to develop and test a novel biomarker feedback intervention relating cotinine levels in the urine of pregnant women with the woman and infant's likely exposure to the tobacco specific nitrosamine and carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone) (NNK). This 5-year project will be conducted in three phases. In Phase 1 the investigators will utilize a non-randomized, clinical observational trial to examine biomarkers of nicotine and carcinogen exposure (urine cotinine and total NNAL [a metabolite of NNK], respectively) among 150 maternal-infant pairs with assessments conducted during pregnancy and at delivery. In Phase 2, the investigators will obtain qualitative feedback on the findings from Phase 1 through individual interviews conducted with 32 women who use tobacco to develop the biomarker feedback intervention messages. Phase 3 will consist of a formative evaluation of the biomarker feedback intervention with 60 pregnant women using a two-group randomized design to assess the intervention's feasibility and acceptability, and the biochemically confirmed abstinence rate at the end of pregnancy. All phases of the project will be guided by a Community Advisory Committee. Each phase is an important step to advance the investigators' understanding of the potential for biomarker feedback as a strategy to help Alaska Native pregnant women quit tobacco use. The potential reach of the intervention is significant from a public health perspective as over 600 tobacco users deliver each year at the Alaska Native Medical Center in Anchorage where the proposed project will take place. Developing effective interventions for tobacco cessation during pregnancy is important to reduce adverse health consequences for the mother and neonate and future risk of tobacco-caused cancers.

This is the third and final phase of the project. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
