Inclusion criteria

• . Male or female, 18 - 60 years of age.
• . General good health, and free of any concomitant conditions or treatment that could interfere with study conduct, influence the interpretation of study observations/results, or put the patient at increased risk during the trial.
• . A history of PAR for a minimum of one year immediately preceding the Screening Visit.
• . A demonstrated sensitivity to at least one allergen known to induce PAR through a standard prick or intradermal test. A positive test is defined as a wheal diameter at least 3 mm larger than the control wheal for the prick test, and 7 mm or greater than the control for the intradermal test. Documentation of a positive result within 12 months prior to the Screening Visit is acceptable.
• . Females of child-bearing potential are currently taking and will continue to use a medically reliable method of contraception for the entire study duration (e.g. oral, injectable, trans-cutaneous or implantable contraceptives or intrauterine devices or double-barrier protection). Women of childbearing potential, or less than 1 year postmenopausal, will require a negative plasma pregnancy test at the Screening Visit as well as at last on-treatment visit.
