Trial Outcomes & Findings for Neuro Biomarkers of Smoking Behavior (NCT NCT03811951)

NCT ID: NCT03811951

Last Updated: 2021-03-02

Results Overview

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.

PRIMARY outcome

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

Population: All the participants were non-smokers

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.

Outcome measures

Outcome measures
Measure
Smokers
All 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. Novolin R: 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.
