NCT06822049

Brief Summary

The study will employ a randomized, parallel-group design with two-stage randomization. After an initial brief screen for basic eligibility, participants will be randomized (within site) to either Remote (R) or In-Person (IP) Intake Groups. During the Intake, detailed consent and eligibility assessment will be completed. Participants who are eligible at the Intake will be randomized (within site and Intake Group) to R or IP Treatment and Assessment Groups. Participants will be followed for 3 months.

Outcome Measures

Primary Outcomes (4)

  • Accrual efficiency/Pre-treatment visits

    Calculated from visit milestones. Of participants who were eligible on the Brief Screen, the percentage who who attend the (Remote vs. In-Person) Intake Visit, a major accrual bottleneck for in-person trials. Although pre-treatment participant loss from Intake to Clinic 1 is typically modest, we will also explore Intake to T/A Visit 1 (first dose of treatment) attrition and overall pre-treatment attrition (from Brief Screen to T/A Visit 1) for each group.

    ~1 month

  • Trial Quality: Retention

    Retention will be assessed using visit milestone data to determine whether each participant achieved each T/A Visit (Visits 2-5) following T/A initiation at T/A Visit 1. We will calculate a continuous metric of retention (0-4; the number of visits completed) for each participant, supplemented by visit-specific data to provide a detailed examination of the time course and overall amount of retention.

    ~3 months

  • Trial Quality: Treatment adherence/utilization (patient-reported)

    As in most studies in the smoking cessation clinical trial literature, we will assess self-reported patch and lozenge use since the previous visit and convert the data to percent adherence separately for patches and lozenges. Pharmacotherapy is initiated at T/A Visit 2; therefore treatment adherence is assessed at T/A Visits 3, 4, and 5).

    8 weeks (assessed at T/A Visits 3, 4, and 5)

  • Trial quality: Biospecimen completion rates

    The number of visits (out of 5; T/A Visits 1-5) for which the biospecimen (expired-air CO) is obtained by the clinical site.

    3 months (assessed at T/A Visits 1,2, 3, 4, and 5)

Study Arms (4)

REMOTE intake AND REMOTE treatment/assessment

OTHER

In this arm, ppts have been randomly assigned to a REMOTE INTAKE eligibility/baseline visit, and subsequently randomized to 5 REMOTE treatment/assessment visits.

In this arm, ppts have been randomly assigned to a REMOTE INTAKE eligibility/baseline visit, and subsequently randomized to 5 IN-PERSON treatment/assessment visits.

Drug: Combination Nicotine Replacement Therapy (patch and lozenge)

IN-PERSON intake, BUT REMOTE treatment/assessment

OTHER

In this arm, ppts have been randomly assigned to an IN-PERSON INTAKE eligibility/baseline visit, and subsequently randomized to 5 REMOTE treatment/assessment visits.

PARALLEL
Model Details: Randomized, parallel-group design. The study employs a two-stage adaptive biased-coin randomization technique. The initial randomization will be generated using a stratified biased coin design with an allocation probability of 0.75 and a randomization list within each stratum will be generated for both Stage I (randomization to remote vs in-person Intake) and Stage II (randomization to remote vs. in-person Treatment/Assessment visits). To optimize the balance in cell sizes across the 4 treatment conditions, the allocation probabilities will be adjusted at 3 study milestones (once 25%, 50%, and 75% of the target sample of 200 participants attend Treatment/Assessment Visit 1). Specifically, the allocation probability will be modified based on the imbalance in the number of participants across conditions who have attended Treatment/Assessment Visit 1.

Data Sharing

IPD Sharing
Will share

We plan to make available the full de-identified data set with metadata through the NAHDAP, a NIDA-funded platform for data sharing/archiving, with a topical focus on behavioral health data. NAHDAP operates under the umbrella of the ICPSR, based at the University of Michigan. Per the ICPSR website, the ICPSR is "the largest social science data archive in the world".

Shared Documents
STUDY PROTOCOL, ICF
Time Frame
Consistent with NIH and Institute of Medicine recommendations, the data will be deposited no later than the publication of the primary study data or one year after each RCTs completion, whichever comes first. There is no planned end date.
Access Criteria
Data submitted for archiving/sharing will be consistent with Inter-university Consortium for Political and Social Research (ICPSR) and the National Addiction and HIV Data Archive Program (NAHDAP) data standards and data stewardship policies and will contain no personal identifiers. Typically, the data are publicly available via a unique digital object identifier (DOI).
