Arms and Interventions

Arm Intervention/treatment
Experimental: EVP-6124 + NicoDerm (Active)
One EVP-6124 capsule ingested orally daily for 12 weeks (84 days) and one NicoDerm patch (Active) daily for first 6 weeks (42 days)
Drug: EVP-6124
One EVP-6124 capsule ingested orally daily for 12 weeks (84 days)
Drug: NicoDerm Patch (Active)

Outcome Measures

Primary Outcome Measures :
  1. Effects of EVP-6124 on 7-day Point-prevalence Smoking Abstinence [ Time Frame: Week 1, 2, 4, 6, 8, 10, 12 ]
    Smoking abstinence is defined as a self-report of smoking no cigarettes for the past 7 days by time-line follow-back, confirmed by expired carbon monoxide (CO) <10 ppm and/or urine cotinine <50 ng/mL.

  2. Difference in Expired Carbon Monoxide (CO) Concentration From Baseline to End Point [ Time Frame: Baseline, Weeks 1, 2, 4, 6, 8, 10, 12 ]
    CO concentration was measured at every visit.


Secondary Outcome Measures :
  1. Effects of EVP-6124 on Cognitive Performance as Measured by the Continuous Performance Test Hit Reaction Time [ Time Frame: Baseline, week 1, week 12 ]
    The Continuous Performance Test (CPT) is a measure of both vigilance/attentional control and response inhibition. During the task, subjects are required to press a button whenever a letter appears on the screen unless that letter is an 'X'. Measures of attentional control will serve as primary measure from this test. Baseline attentional impairment is associated with reduced odds of abstinence, abstinence differentially worsens performance on this measure in those with baseline attentional impairment, and NRT improves performance on a similar measure.

  2. Safety and Tolerability of EVP-6124 Alone or Combined With NRT [ Time Frame: Weeks 1-12 ]
    All AEs (adverse experiences) spontaneously reported by subjects and/or observed by investigator and evaluation of physical examinations, prior and concomitant medications, clinical laboratory tests, ECGs, and vital signs measurements. Data was collected at every visit and was analyzed as aggregate at the end of week 12

  3. Effects of EVP-6124 on Working Memory as Measured by the N-Back Task Reaction Time [ Time Frame: Baseline, week 1, week 12 ]
    This task is a standard measure that can assess working memory performance under varying levels of task demand. Subjects are presented with a stream of stimuli, and the task is to decide for each stimulus whether it matches the one presented N items before. The processing load can be varied systematically by manipulating the value of N, which is expressed with changes in accuracy and reaction time. The number of errors as well as reaction times increase monotonically with increasing levels of N. The n-back task is sensitive to nicotine administration and abstinence effects. Here we present reaction time (RT)
