Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort 1

Subjects will be randomized to receive either experimental drug (N=9) or matching placebo (N=3).

Group Type OTHER

Varenicline Tartrate

Intervention Type DRUG

Varenicline 1.8 mg AMT-8 controlled release tablets administered twice a day for 14 days.

Cohort 2

Subjects will be randomized to receive either experimental drug (N=9) or matching placebo (N=3).

Group Type OTHER

Varenicline Tartrate

Intervention Type DRUG

Planned dose is Varenicline 2.4 mg AMT-8 controlled release tablets administered twice a day for 14 days. Actual dose may be adjusted based on emerging data from prior dose cohorts.

Cohort 3

Subjects will be randomized to receive either experimental drug (N=9) or matching placebo (N=3).

Group Type OTHER

Varenicline Tartrate

Intervention Type DRUG

Planned dose is Varenicline 3 mg AMT-8 controlled release tablets administered twice a day for 14 days. Actual dose may be adjusted based on emerging data from prior dose cohorts.

Optional Cohort 4

Subjects will be randomized to receive either experimental drug (N=9) or matching placebo (N=3).

Group Type OTHER

Varenicline Tartrate

Intervention Type DRUG

The dose to be administered is not yet determined and will be based on emerging data from prior dose cohorts. The dose will be administered as Varenicline AMT-8 controlled release tablets twice a day for 14 days. The doses to be tested may be lower, higher or repeat a previously tested dose and may include a titration.

Optional Cohort 5

Subjects will be randomized to receive either experimental drug (N=9) or matching placebo (N=3).

Group Type OTHER

Varenicline Tartrate

Intervention Type DRUG

The dose to be administered is not yet determined and will be based on emerging data from prior dose cohorts. The dose will be administered as Varenicline AMT-8 controlled release tablets twice a day for 14 days. The doses to be tested may be lower, higher or repeat a previously tested dose and may include a titration.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Healthy male and/or female subjects between the ages of 18 and 55 years, inclusive. Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12 lead ECG and clinical laboratory tests.
* Currently smoking and have smoked an average of at least 10 cigarettes per day during the past year, with no period of abstinence greater than 3 continuous months in the past year.

Exclusion Criteria

* Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing).
* Pregnant or nursing women are excluded; women of childbearing potential (WOCBP) who are unwilling or unable to use an acceptable method of contraception as outlined in the protocol from at least 14 days prior to study medication administration until completion of protocol-required procedures are excluded.
* Subjects with an estimated creatinine clearance (CLcr) \<80 mL/min derived using the method of Cockcroft and Gault.
