About this study

Official title: Neurologic Biomarkers of Smoking Behavior

The purpose of this study is to evaluate cognition in smokers and nonsmokers. It involves administration of intranasal insulin (Novolin R), an investigational medication followed by a brief non-invasive cognitive test. All participants will receive both Novolin R and placebo in two separate testing sessions.

Read the detailed description

This program of research focuses on identifying neurologic biomarkers of smoking behavior in order to develop individualized smoking cessation aids. The intranasal insulin administered is an investigational drug and has been granted IND status by the FDA (IND#129432). During the times of drug effects, the investigators will evaluate a biomarker using computerized tasks. Non-smokers and smokers will participate in two testing sessions where the biomarker will be critically evaluated after administration of intranasal insulin and compared to the cognitive processes elicited by placebo administration.

What participants receive

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

  • Novolin RDrug

    Also called McKesson Corporation, Novo Nordisk

    Novolin R is a sterile, clear, aqueous, and colorless solution that contains human insulin (rDNA origin) 100 units/mL, glycerol 16 mg/mL, metacresol 3 mg/mL, zinc chloride approximately 7 mcg/mL and water for injection. The pH (potential Hydrogen) is adjusted to 7.4. Hydrochloric acid 2N (concentration) or sodium hydroxide 2N may be added to adjust pH. Novolin R vials are latex-free. The drug substance is being purchased from McKesson.

Study groups in NCT03811951
Study groupRoleWhat they receive
SmokersExperimentalAll participants receive both Novolin R (experimental drug) and 14% NaCl (Sodium Chloride) solution (placebo), to be administered in randomly assigned order on two separate testing sessions. During administration of either Novolin R or 14% NaCl, participants will receive 1 spray in each nostril every 3 minutes for a total of 6 sprays. The nasal spray bottle delivers 0.1 ml of liquid per spray. Since the concentration of insulin in Novolin R is 100 IU/mL, six sprays will deliver a 60 IU dose.

Non-SmokersExperimentalAll participants receive both Novolin R (experimental drug) and 14% NaCl solution (placebo), to be administered in randomly assigned order on two separate testing sessions. During administration of either Novolin R or 14% NaCl, participants will receive 1 spray in each nostril every 3 minutes for a total of 6 sprays.

What is being measured

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

  1. Go/No-Go Accuracy

    Go/No-Go is used to measure a participants capacity for sustained attention and response control. The test requires a participant to perform an action given certain stimuli (e.g., press a button - Go) and inhibit that action under a different set of stimuli (e.g., not press that same button - No-Go).

    Average of the 2 runs (run 1 - insulin; run 2 - placebo) were calculated for mean reaction time (+SEM) of smokers and non-smokers on no-go stimuli. The minimum reaction time was 23.08 ms and the maximum reaction time was 97.44 ms. The higher mean value represents slower the reaction time, and the lower mean value represents quicker the reaction time. The higher value means that participants have difficulties with inhibiting a prepotent response. The values do not represent a better or worse outcome.

    Measured: From time of drug administration to 70 minutes following drug administration, up to 90 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Novolin R in people with Smoking Cessation, run by University of Illinois Chicago 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 7 inclusion and 14 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 2 Mar 2021. 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 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?

Yes. Results are posted in the registry (first posted 2 Mar 2021). 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?

Go/No-Go Accuracy (time frame: From time of drug administration to 70 minutes following drug administration, up to 90 minutes). 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 NCT03811951, which also lists 15 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 2 Mar 2021.
