About this study

Official title: Developing Medication For Tobacco Addiction: NMDA Agents

One of nicotine's effects on the body is at the level of the NMDA receptors in the brain. Memantine is a drug that also affects NMDA receptors, making it a candidate for the treatment of nicotine addiction. The purpose of this study is to evaluate the effectiveness of memantine using a laboratory model of tobacco addiction. The investigators will compare the effects of memantine with bupropion, medication currently used to facilitate smoking cessation.

Read the detailed description

Tobacco use is the leading preventable cause of death in the United States. Recent research on the effects of nicotine on the brain and behavior presents an opportunity to advance medication development. Neurotransmission at NMDA receptors in the brain is associated with learning and memory and has been linked to many of nicotine's effects on humans. It is possible that altering NMDA neurotransmission may be helpful in treating nicotine addiction.

The goal of this study is to develop a laboratory model for early-stage testing of new and existing compounds for the treatment of tobacco and nicotine addiction. Specifically, the study will assess the effect of memantine, a non-competitive NMDA antagonist, versus bupropion, a medication currently used to facilitate smoking cessation, on various behavioral aspects related to smoking behavior, including reinforcement and cue-reactivity.

This double-blind, randomized assignment study will consist of three distinct phases (placebo, bupropion, and memantine). Each phase will include 10 days of outpatient medication maintenance, followed by 3 days of inpatient testing. During the outpatient phase, study visits will occur every 2 to 3 days. At these visits, compliance and side effects of medication will be monitored, smoking diaries will be collected, and medication will be dispensed. During the inpatient period participants will be allowed to smoke only at designated times. A variety of assessment will be conducted, including abstinence symptoms, acute effects of cigarettes, responses to cigarette cues, and cigarette self-administration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Memantine and bupropion in people with Tobacco Use Disorder, 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 5 inclusion and 11 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 21 May 2018. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Response to cigarette cues (time frame: Days 11-13). The study lists 2 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 21 May 2018; AzTrials last refreshed its copy on 8 Nov 2026.
