Trial Outcomes & Findings for Evaluation of the Nicotine Lozenge in Relief of Provoked Acute Craving (NCT NCT01466361)

NCT ID: NCT01466361

Last Updated: 2019-08-28

Results Overview

Participants completed a nicotine craving assessment consisting of following five items: I have a desire for a cigarette right now, if it were possible I would smoke right now, All I want right now is a cigarette, I have an urge for a cigarette, I crave a cigarette right now. All participants indicated their craving intensity on a pre-drawn 100 mm scale ranging from 0 (disagree) to 100 (agree). At the end of the craving assessment period, mean VAS score (in mm) was measured.

Participant Flow

Participants were recruited at the clinical site.

Participants who smoked more than 5 cigarettes per day were included in the study. Participants were stratified to treatments according to their smoking status: heavy smokers: smoking greater than 20 cigarettes per day and light smokers: smoking between 6 - 20 cigarettes per day.

PRIMARY outcome

Timeframe: Baseline, 1, 3, 5, 10 and 15 minutes post-treatment

Population: Intent to treat (ITT) population: All randomized participants with at least one cravings assessment measurement post dose were analyzed. No data was imputed in case of dropouts or missing data.

Participants completed a nicotine craving assessment consisting of following five items: I have a desire for a cigarette right now, if it were possible I would smoke right now, All I want right now is a cigarette, I have an urge for a cigarette, I crave a cigarette right now. All participants indicated their craving intensity on a pre-drawn 100 mm scale ranging from 0 (disagree) to 100 (agree). At the end of the craving assessment period, mean VAS score (in mm) was measured.

SECONDARY outcome

Timeframe: Baseline prior to provoked craving paradigm, baseline post provoked craving paradigm

Responders were defined as participants with an increase of at least one point (on the 100 point VAS scale) from baseline prior to provoked craving paradigm (B1) to baseline post provoked craving paradigm (B2) on the average cravings score. Percentage of these responders was calculated to evaluate the provocation rate.

SECONDARY outcome

Timeframe: Baseline, 0 minute, 60 minutes and 5 days post treatment

Population: Safety population: All randomized participants who received the study treatments were considered evaluable for safety.

AE was defined as any new untoward medical occurrence or worsening of a pre-existing medical condition which does not necessarily have a causal relationship with study treatment/s. SAE was defined as any untoward medical occurrence that at any dose results in death; is life threatening; requires hospitalization or prolongation of existing hospitalization results in disability/ incapacity; is a congenital anomaly/ birth defect.
