Exclusion criteria

• Have clinically significant physical findings of nasal anatomical deformities causing greater than 50% obstruction

• Previous participation in a budesonide study within three months prior to the Screening Visit.

• Participation in any investigational drug trial within the 30 days preceding the Screening Visit, and thereafter.

• A known hypersensitivity to any corticosteroid or any of the excipients in the formulation of the investigational drug

• History of severe respiratory infection or disorder

• History of alcohol or drug abuse

• History of a positive test for HIV, hepatitis B or hepatitis C.

• Use of any of the prohibited medications within the identified exclusion periods

• Use of antibiotic therapy for acute conditions within 14 days prior to the Screening Visit and thereafter. Low doses of antibiotics taken for prophylaxis are permitted based on the judgment of the Investigator if therapy was started prior to the Screening Visit AND is expected to continue throughout the study.

• Initiation of immunotherapy or dose escalation during the study period. However, patients may be considered for inclusion if the immunotherapy was initiated 90 days or more prior to the Screening Visit AND if the dosing was stable (maintenance dose) for 30 days or more prior to the Screening Visit. No immunotherapy injections may be received within 48 hours prior to a ragweed pollen exposure visit.

• Non-vaccinated exposure to or active infection with chickenpox or measles within the 21 days preceding the Screening Visit.

• Exposure to systemic corticosteroids for any indication, chronic or intermittent (e.g., arthritis), during the 60 days preceding the Screening Visit, or presence of an underlying condition that can reasonably be expected to require treatment with corticosteroids during the course of the study.

• Use of topical corticosteroids in concentrations in excess of 1% hydrocortisone or equivalent for dermatological conditions within 30 days prior to the Screening Visit

• History of epilepsy or seizures

• History of coronary heart disease, uncontrolled hypertension, or other clinically significant cardiovascular disease.

• Have any of the following conditions that are judged by the investigator to be clinically significant and/or affect the patient's ability to participate in the clinical trial:

  • Impaired hepatic function including alcohol related liver disease or cirrhosis
  • History of ocular disturbances (e.g., glaucoma or posterior subcapsular cataracts)
  • Any systemic infection
  • Hematological, renal, endocrine (except for controlled diabetes mellitis or postmenopausal symptoms or hypothyroidism)
  • Gastrointestinal disease
