About this study

Official title: Treatment of Smokeless Tobacco Users

Smokeless tobacco (ST), which includes both chewing tobacco and snuff, has as many health risks associated with its use as cigarettes. While there are many treatment programs that focus on stopping tobacco use, there are no interventions that specifically focus on reducing tobacco use. This study will evaluate the effectiveness of nicotine lozenge at reducing tobacco use in ST users.

Read the detailed description

Individuals who use ST are at risk for developing heart disease, stroke, high blood pressure, and cancer. Other long-term effects include tooth abrasion, gum recession, and loss of bone in the jaw. Many individuals who use ST recognize the health risks associated with ST, but either do not want to quit or feel that it is impossible to quit. For these individuals, tobacco reduction may be an important transitional goal, either prior to quitting or as a treatment endpoint. The need exists for a program specifically aimed towards reducing, rather than quitting, tobacco use. The purpose of this study is to evaluate the effectiveness of nicotine gum at reducing ST use, as well as assessing the motivation to either quit or sustain lower levels of ST use.

This 8-week study will enroll frequent users of ST. Participants will be randomly assigned to receive either nicotine lozenge plus behavioral counseling or behavioral counseling alone. All participants will be asked to alternate use of their usual ST brand with nicotine lozenge or placebo in order to reduce nicotine intake by 50% during the first 4 weeks and by 75% the following 4 weeks. Participants will be required to maintain a daily tobacco use diary. Study visits will occur once a week. Tobacco levels will be monitored with urine tests, and questionnaires will be completed to assess tobacco use. Follow-up evaluations will occur 12 and 26 weeks following the end of treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Nicotine Lozenge and Behavioral Counseling in people with Tobacco Use Disorder, run by National Institute on Drug Abuse (NIDA) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reduction in tobacco use (measured by tobacco daily diary at Week 8, and the 12- and 26-week follow-up evaluations) (time frame: 8, 12 and 26 weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jan 2017.
