Smoking by IV Pulsed Nicotine

July 13, 2021 updated by: Mehmet Sofuoglu, Yale University

Modeling Tobacco Smoking by IV Pulsed Nicotine in Smokers

To establish a dose-effect curve for nicotine's abuse potential as a function of nicotine dose and delivery rate. Pulsed IV nicotine administration will be used as it closely matches nicotine delivery by inhaled tobacco use.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Both sub-studies will enroll male and female tobacco cigarette smokers. This study will examine the feasibility of the proposed study parameters in a total of 10 completers. In a crossover design, participants will be tested under 5 conditions: 0.2 mg nicotine delivered over 2.5 minutes (5 pulsed-nicotine deliveries), 0.2mg nicotine delivered over 10 min (20 pulsed-nicotine deliveries), 1.0 mg nicotine delivered over 2.5 minutes (5 pulsed-nicotine deliveries) and 1.0 mg nicotine delivered over 10 min (20 pulsed-nicotine deliveries). The main outcome measures will be self-report drug effects and urges to smoke cigarettes.

The investigators hypothesize that the abuse potential and alleviation of smoking urges are produced by nicotine as a function of nicotine dose and delivery rate.

This study is complete with 13 enrolled and 10 completers

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 35 years (ADULT)

Accepts Healthy Volunteers
