Inclusion Criteria:

1. Patients must have a clinical history of SAR with seasonal onset and offset of nasal and ocular allergy symptoms at least during each of the last two ragweed allergy seasons.
2. Adults (males and females) aged 18 to 65, inclusive.
3. Patients must have documentation of a positive skin test within 12 months of screening to ragweed or a positive skin prick and/or intradermal test for ragweed allergen at Visit 1. A positive response is defined as a wheal diameter of at least 3 mm larger than the negative control for the skin prick test or at least 7 mm larger than the negative control for the intradermal test.

4. Non-pregnant, non-lactating women not of childbearing potential who are post-menopausal [defined as at least 6 months natural spontaneous amenorrhea], or are surgically sterile (hysterectomy; bilateral oophorectomy; bilateral tubal ligation with surgery at least 6 weeks prior to study initiation). Surgical sterility should be supported with clinical documentation.

   Females must have a confirmed absence of pregnancy according to a negative serum pregnancy test or urine pregnancy test at the times described in Section 11.

   Female subjects of child bearing potential must agree to use a reliable and highly effective method of birth control with a low failure rate (i.e. less than 1% per year) when used consistently and correctly (e.g. implants, injectables, combined oral contraceptives, some IUDs, sexual abstinence or vasectomised partners) during the trial, as judged by the investigator. For subjects using a hormonal contraceptive method, information regarding the product under evaluation and its potential effect on the contraceptive should be addressed.

5. Pregnancy or breastfeeding, or plans to become pregnant or donate gametes (ova or sperm) for in vitro fertilization during the study period, or for 30 days following the study period.
