Trial summary

The purpose of the overall parent study is to determine the impact of gender and hormones (estradiol, progesterone, testosterone and cortisol) on responses to stress and smoking cues presented in daily, "real-world" cue presentations compared to a final cue session in a lab.

About this study

The purpose of the overall parent study is to determine the impact of gender and hormones (estradiol, progesterone, testosterone and cortisol) on responses to stress and smoking cues presented in daily, "real-world" cue presentations compared to a final cue session in a lab. In addition, in the portion of the study that incorporates clinical trials elements and is reported here, the study will examine the impact of a single dose of oxytocin (chemical produced in the body) versus placebo (inactive substance) on reactivity to a stress procedure (Trier Social Stress Task) in smokers.

The overall parent study involves a cue presentation technology known as "CREMA" (Cue Reactivity Ecologic Momentary Assessment) which delivers four daily cue presentations to you on a handheld device during your everyday routine. Additionally, the study involves daily collection of saliva samples for hormonal testing. These daily procedures will provide information about the role of cues and hormones in daily life. The clinical trial portion of the study (reported here) consists of measures collected within the laboratory.

Read the detailed description

Despite considerable advances in treatment development, cigarette smoking remains the leading cause of preventable death in the United States, and most smokers engaged in treatment are unsuccessful in quitting. The burden of illness is disproportionately borne by female smokers, who are less responsive to cessation interventions than males. The relationships between stress, craving, and smoking behavior are recognized as key factors underlying gender differences in nicotine dependence, but must be better understood and characterized to yield avenues for interventions addressing this critical health disparity.

In prior and ongoing SCOR studies, our research team has demonstrated gender and menstrual cycle/sex hormone influences on reactivity to laboratory-presented cues. Building from these laboratory findings, we propose taking two important next steps: (1) evaluating the experience of craving in the "real world" natural environment of female and male smokers, and (2) examining the impact of a safe and novel pharmacological intervention (oxytocin) on stress reactivity in female and male smokers.

If, as hypothesized, gender, sex hormones, and oxytocin administration influence the relationships between stress, craving, and smoking behavior, the findings could substantially address a key gender-related health disparity. Such knowledge could also inform the development of gender-specific interventions to enhance female smokers' response to cessation treatments. Therefore, the knowledge to be gained from the proposed study may yield significant public health benefits.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Craving Response to Trier Social Stress Task

    The TSST is the gold standard for evoking stress response in the laboratory. The participant must deliver a speech as though speaking to a group of hiring managers. The participant has 5 min to prepare, then three individuals unfamiliar to the participant (the audience) enter the room and are seated; the participant is instructed give the speech (without notes). The speech is delivered for 5 min, then the participant is instructed to serially subtract 13 from 1,022 as quickly and accurately as possible. The mental math recitation continues for 5 min, and at its conclusion, the spokesperson instructs the participant to stop and be seated, and the audience leaves the room. The total time for the TSST is 15 min.

    The Craving Questionnaire (Carter \& Tiffany, 2001) is the sum of 4 items, each rated 1-5 on a Likert scale, with total score ranging 4-20, and higher scores indicating higher craving.

    Measured: Immediately after the conclusion of the TSST

The mental math recitation continues for 5 min, and at its conclusion, the spokesperson instructs the participant to stop and be seated, and the audience leaves the room. The total time for the TSST is 15 min.

    The single stress item is derived from the CREMA Mood/Stress Assessment (Warthen \& Tiffany, 2009), asking how stressed the participant felt at that time, on a 5-point Likert scale, ranging 1-5 with higher score indicating feeling more stressed

    Measured: Immediately after the conclusion of the TSST

  2. Cortisol Response to Trier Social Stress Task

    Cortisol measured immediately following the Trier Social Stress Task, to evaluate physiological stress response.

    Measured: Immediately following the Trier Social Stress Task

Questions about this trial

What is this clinical trial studying?

A study testing Oxytocin in people with Nicotine Dependence, run by Kevin Gray, MD 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 7 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 1 Jul 2020. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Craving Response to Trier Social Stress Task (time frame: Immediately after the conclusion of the TSST). 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 1 Jul 2020.
