Trial summary

The investigators previously developed a cigarette cue extinction treatment (CET) procedure in non-treatment seeking volunteer smokers in our nicotine laboratory. The goal of Cue Extinction Treatment is to un-pair a behavioral or autonomic response from the stimulus that triggers it. Read more about this study

About this study

The investigators previously developed a cigarette cue extinction treatment (CET) procedure in non-treatment seeking volunteer smokers in our nicotine laboratory. The goal of Cue Extinction Treatment is to un-pair a behavioral or autonomic response from the stimulus that triggers it. This is accomplished through repeated exposure to that trigger, while removing the patient's ability to act out the conditioned response. In the present study, the trigger is a lit cigarette, and the response the investigators seek to un-pair is cigarette craving. In the procedure the investigators have previously developed and intend to use again, the participant is shown a pack of his brand of choice cigarettes. The researcher removes a cigarette from the pack, lights it, and asks the participant to hold the cigarette without smoking it for 90 seconds. This procedure is repeated seven times over the course of a six-hour lab session. The investigators hope to boost the clinical response to smoking cue exposure therapy in quitters on NRT (nicotine replacement therapy) pretreatment by pharmacological augmentation with the partial NMDA receptor agonist D-cycloserine (DCS). Behavioral extinction training is a form of learning that may be modulated by NMDA receptor mediated glutamate transmission. The study's main hypothesis is that the partial NMDA receptor agonist D-cycloserine (DCS) facilitates cue exposure training and may prevent relapse to smoking. The aim of the proposed study is to assess whether DCS-facilitation of cue-exposure therapy improves abstinence among smokers on the nicotine patch seeking treatment. Development of an effective treatment strategy to enhance the effectiveness of NRTs would have a direct and significant positive impact on public health.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing D-cycloserine, Nicotine Replacement Therapy (patch) and Smoking Cue Exposure in people with Cigarette Smoking, run by New York State Psychiatric Institute 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 6 inclusion and 10 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: withdrawn, as of the sponsor's last update on 8 Oct 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.

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 was withdrawn before enrolling participants, so there are no results.

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?

Number of Cigarettes Smoked (time frame: 3 months). 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 8 Oct 2020.
