A Single Dose Study Investigating the Absorption and Elimination as Well as the Tolerability of Varenicline Transdermal Delivery System (e.g., a Patch) as Compared to Oral Varenicline in Adult Smokers.

1. To evaluate the absorption and elimination of varenicline Formulation A transdermal delivery system [TDS (patch)] compared to varenicline immediate release tablet (CHANTIX®). 2. To evaluate the adhesion of the varenicline Formulation A patch. 3. To evaluate the safety and tolerability of a single application of the varenicline patch and a single oral dose of the varenicline immediate release tablet (CHANTIX®).

Treatment and study plan

varenicline tartrate

Drug

Single dose of 2.0 mg oral Chantix (varenicline) immediate release tablet formulation

Other names: varenicline, Chantix, Champix

varenicline free base

Drug

A single 2.0 mg dose of varenicline transdermal delivery system applied to the skin for a 24 hour period.

Other names: varenicline

Primary outcomes

  1. Rating Scale for Adhesive Residue (e.g., assesses how well the transdermal delivery system remains adhered to subject's skin)

    Time frame: 24 hours per Arm

  2. Rating Scale for Assessment of Application Site Dermal-Erythema, Edema, and Irritation (assesses skin irritation associated with varenicline transdermal delivery system)

    Time frame: 6 days per Arm

  3. Pharmacokinetic endpoints: plasma varenicline area under the curve (AUClast and AUCinf), maximum plasma concentration (Cmax), terminal half-life (t 1/2) and time of maximum plasma concentration (Tmax)

    Time frame: 6 days per Arm

Secondary outcomes

  1. Assessment of Adhesidue/Cold Flow Assessment (assesses extent of adhesive residue which remains on the skin at application site as well as the adhesive flow beyond the application site border

    Time frame: 24 hours per Arm

  2. Evaluation of adverse events (including the visual analog scale for nausea), safety laboratory testing, electrocardiogram, vital signs

    Time frame: 6 days per Arm
