About this study

Nicotine dependence has not been sufficiently addressed in current state-of-the-science cessation interventions for pregnant smokers. The weight of the evidence from the general population of smokers suggests that nicotine replacement therapies may be beneficial cessation aids for pregnant smokers who are unable to stop smoking. The tremendous potential of these therapies for promoting smoking cessation among pregnant women creates a pressing need for decision tools and protocols to encourage treatment adherence that is essential for rigorous evaluation of the effectiveness of OTC NRT when provided as part of prenatal care. The results of this research could be directly translated to the improvement of obstetrical care providers' clinical practices. Medically supervised use of OTC NRT by pregnant smokers is an alternative to continued smoking that has the potential to substantially increase rates of smoking cessation during pregnancy.

Read the detailed description

The proposed five-year study is designed to evaluate the effectiveness of providing over-the-counter (OTC) nicotine replacement therapy, choice of gum, lozenge or patch, (NRT) to promote prepartum smoking cessation. Proposed is a two-arm design. Eligible pregnant women (N=300) will be randomized to either: Arm 1, Tailored Cognitive Behavioral Treatment (TCBT, n=100) that provides women with customized risk information about smoking and nicotine, the potential harms to the fetus and encouragement of appropriate behavioral skills building; or Arm 2, TCBT + NRT - the tailored intervention incorporating NRT information plus choice of patch or gum (n=200). The intervention will include 5 face-to-face contacts as part of prenatal visits and 1 telephone counseling session. Primary outcome measures will be biochemically validated 7-day prevalent abstinence rates at the 19-27th and 29-37th week of pregnancy. Secondary outcomes will include 7-day prevalent abstinence rates at 12 weeks postpartum, serious quit attempts, compliance with NRT, and use of materials. Saliva cotinine will be measured among all women at baseline, the 27-35th week of pregnancy, and 12 weeks postpartum. The significance of this project is that it relies on transdisciplinary collaborations to extend the science in nicotine replacement therapies to a population that could derive substantial health benefits. Moreover, the study results have immediate potential to inform clinical recommendations for integrating nicotine replacement into prenatal care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Motivational interviewing for smoking cessationBehavioural

    Also called Nicoderm CQ (patch), Nicorertte (gum), Commit (lozenge)

    All participants received a tailored CBT (TCBT) intervention that included: a written self-help guide, info about the importance of reducing nicotine exposure to the fetus, 5 face to face and 1 telephone counseling session. Women in the TCBT + NRT arm were guided through a process of deciding on nicotine gum, lozenge or patch. To minimize fetal exposure, the dose of NRT was customized to the woman's current level of smoking. Women who smoked 5-10 cigarettes a day were given the 14 mg patch or instructed to use one 2 mg lozenge or 2 mg piece of gum to replace each cigarette she usually smoked per day. Those who smoked 11 cigarettes or more per day were given the 21 mg patch or instructed to use no more than one lozenge (2 mg) or piece of gum (2 mg) to replace each cigarette she usually smoked per day, not to exceed 15 lozenges or pieces of gum per day.

  • Cognitive behaviors therapyBehavioural

    6 counseling sessions delivered over the phone or in person

  • CBT + NRTDrug

    Also called Nicoderm CQ (patch), Nicorette (gum), Commit (lozenge)

    Includes CBT from arm 1 plus choice of NRT (lozenge, gum, or patch) tailored to smoking amount

1 - CBT CounselingActive comparatorParticipants in this arm received a tailored CBT (TCBT) intervention that included: a written self-help guide, feedback about the importance of reducing nicotine exposure to the fetus, 5 face to face and 1 telephone counseling session.
Receives: Behavioral: Motivational interviewing for smoking cessation; Behavioral: Cognitive behaviors therapy
2 - Counseling + NRTExperimentalWomen in this arm received the TCBT described in Arm 1, plus their choice of NRT. To minimize fetal exposure to nicotine for women in the TCBT+NRT arm, the dose of NRT are customized to the woman's current level of smoking. Women who smoke 5-10 cigarettes a day will be given the 14 mg patch or instructed to use one 2 mg lozenge or 2 mg piece of gum to replace each cigarette she usually smokes per day. Those who smoke 11 cigarettes or more per day will be given the 21 mg patch or instructed to use no more than one lozenge (2 mg) or piece of gum (2 mg) to replace each cigarette she usually smokes per day, not to exceed 15 lozenges or pieces of gum per day.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 4 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: stopped early, as of the sponsor's last update on 21 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 was stopped early (reason given: was terminated due to meeting a priori stopping rule set by DSMB). Results are not available in the source record.

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?

Biochemically-validated smoking cessation (time frame: middle and late pregnancy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00224419, which also lists 5 linked publications.

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 21 Jul 2014.
