About this trial

The purpose of this study is to refine and pilot an intervention using the Nicotine Metabolite Ratio (NMR) to inform the selection of pharmacologic treatment to increase smoking abstinence among Alaska Native and American Indian people. This is a single-arm pilot trial to assess and improve acceptability and feasibility.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Alaska Native or American Indian person by self-report

eligible for or already receiving services at Southcentral Foundation (SCF)

age 18 years or older

daily smoking in the past 30-days

Disqualifiers

Participated in the prior study phase

participated in a cessation program during the past 3 months

their provider has not approved varenicline in their referral to the Quit Tobacco Program

has history of serious hypersensitivity or skin reactions to varenicline

Trial design

Design model

Single group

Treatments tested in this trial

  • Nicotine Metabolite Ratio

    Other intervention

    Blood specimens will be drawn, in clinic, by clinical staff trained in blood collection (e.g., certified medical assistant, nurse). Through regular clinic procedures, lab staff will ship for processing to Quest. Quest uses liquid chromatography tandem mass spectrometry with a limit of detection of 2ng/ml for all analytes and will quantify NMR within 3-6 days of sample arrival. Samples will be consumed during testing. Results of NMR will be returned to primary care providers, and NMR-informed medication recommendations will be made to participants.

Trial outcomes

Primary outcomes

1

Feasibility of intervention implementation: Enrollment

Proportion of eligible persons who enroll

Time frame
Beta phase (n=10) 6 weeks; Pilot phase (n=40) 6 weeks, 12 weeks, 26 weeks
2

Feasibility of intervention implementation: Treatment recommendations

Proportion who use treatment recommended by NMR results

Time frame
Beta phase (n=10) 6 weeks; Pilot phase (n=40) 6 weeks, 12 weeks, 26 weeks
3

Feasibility of intervention implementation: Semi-structured interviews

Qualitatively, based on semi-structured interviews with a selection of participants and care team/administrators, thematic analysis will explore barriers and facilitators to using metabolism-informed care, as well as fidelity challenges in adhering to the recommended treatment.

Time frame
Beta phase (n=10) 6 weeks; Pilot phase (n=40) 6 weeks, 12 weeks, 26 weeks
4

Acceptability of metabolism-informed intervention: Quantitative

Mean of fourteen, 3-point, Likert-scale survey responses (agree/neither agree nor disagree/disagree, with a "prefer not to answer" option). These items will assess intervention and process acceptability including timeliness of the procedures and recommendation, composition of the team, clarity of communication, ease of understanding pilot measures, willingness to recommend, and satisfaction. These items will be combined into a summary score indicating overall acceptability of the intervention.

Time frame
Beta phase (n=10) 6 weeks; Pilot phase (n=40) 6 weeks, 12 weeks, 26 weeks

Secondary outcomes

1

Smoking Cessation: Self-report

self-report of cigarette smoking for the past 7 days

Time frame
Beta phase (n=10) 6 weeks; Pilot phase (n=40) 6 weeks, 12 weeks, 26 weeks
2

Smoking Cessation: Expelled CO

expelled CO\<4ppm according to a handheld breath monitor which connects to a mobile device (iCO Smokerlyzer®, Bedfont Scientific)

Time frame
Beta phase (n=10) 6 weeks; Pilot phase (n=40) 6 weeks, 12 weeks, 26 weeks
3

Smoking Cessation: Nicotine <10ng/mL

nicotine \<10ng/mL measured by a saliva test strip (Accutest® NicAlert Saliva Collection Kit)

Time frame
Beta phase (n=10) 6 weeks; Pilot phase (n=40) 6 weeks, 12 weeks, 26 weeks
