participate. Subject must understand and be willing, able, and likely to comply with
study procedures and restrictions. Subject must be able to read, comprehend, and
record information in English.

- Subject is treatable on an outpatient basis.

- Age: >=18 years of age at Visit 1.

- Gender: Male or eligible female subjects. A female subject is eligible to participate
if she is of non-childbearing potential (i.e., physiologically incapable of becoming
pregnant, including any female who is post-menopausal or surgically sterile).
Surgically sterile females are defined as those with a documented hysterectomy and/or
bilateral oophorectomy or tubal ligation. Post-menopausal females are defined as being
amenorrhoeic for greater than 1 year with an appropriate clinical profile, e.g., age
appropriate, history of vasomotor symptoms. OR Childbearing potential with a negative
pregnancy test at screening and agreeable to using one of the acceptable contraceptive
methods consistently and correctly (i.e., in accordance with the approved product
label and the instructions of the physician for the duration of the study). An
eligible female is also not lactating nor planning on becoming pregnant during the
study.

- Diagnosis of SAR, defined as documented clinical history or physician verification of
subject reported historical SAR during each of the last two fall allergy seasons and a
positive skin prick test (wheal >=3 millimeter [mm] larger than the negative control)
to a prevalent local fall allergen within 12 months prior to Visit 1 or at Visit 1.

- Adequate exposure to local fall pollen: Subject resides within a geographical region
where exposure to the local fall pollen to which they are sensitized is expected to be
moderate or greater during the study period. Subject does not plan to travel outside
the geographical region where exposure to local fall pollen to which they are
sensitized is expected to be moderate or greater for more than 48 hours during the
study period.

At Visit 2, the subject must meet the following criteria

- Eligible subjects will need to have moderate to severe SAR symptoms, defined as a
morning rTNSS of >=7 on at least four of the last seven days leading up to
randomization. This includes the AM assessment on the morning of the randomization
visit at Visit 2.

- Subjects should demonstrate at least a 70% compliance rate with both their placebo
run-in study medications and their e-diary completion prior to randomization. This
period includes the day of Visit 1 until the day before randomization at Visit 2.

- Subjects should have no significant change in medical condition(s) that would have
been exclusionary at Visit 1.

- Subjects should not have used any prohibited medications that are detailed in the
inclusion/exclusion criteria (including prohibited allergy medications).

- Subjects should not have travelled outside the local pollen region for more than 48
hours during the run-in period.

Exclusion Criteria

- Significant concomitant medical conditions, defined as but not limited to:

Historical or current evidence of a clinically significant uncontrolled disease of any body
system (e.g., tuberculosis, psychological disorders, eczema, uncontrolled asthma).
Significant is defined as any disease that, in the opinion of the investigator, would put
the safety of the subject at risk through study participation or which would confound the
interpretation of the study results if the disease/condition exacerbated during the study.

A severe physical obstruction of the nose (e.g., deviated septum or nasal polyp) or nasal
septal perforation that could affect the deposition of intranasal study drug.

Nasal (e.g., nasal septum), ocular, or throat injury, or surgery to these areas in the last
3 months.

Rhinitis medicamentosa. Bacterial or viral infection (e.g., common cold) of the eyes or
upper respiratory tract within two weeks of Visit 1 or during the screening period.

Documented evidence of acute or significant chronic sinusitis, as determined by the
individual investigator.

Current or history of glaucoma and/or cataracts or ocular herpes simplex. Physical
impairment that would affect subject's ability to safely and fully participate in the
study.

Clinical evidence of a Candida infection of the nose. History of psychiatric disease,
intellectual deficiency, poor motivation, substance abuse (including drug and alcohol) or
other conditions that will limit the validity of informed consent or that would confound
the interpretation of the study results.

History of adrenal insufficiency.

- Use of corticosteroids, defined as: Intranasal corticosteroid within four weeks prior
to Visit 1 and during the treatment period. Inhaled, oral, intramuscular, intravenous,
ocular, and/or dermatological corticosteroid (with the exception of hydrocortisone
cream/ointment, 1% or less) within eight weeks prior to Visit 1 and during the
treatment period.

- Use of allergy medications, within a timeframe relative to Visit 1, that would prevent
the medication from being eliminated and/or have an effect. Exclusionary timeframes
relative to Visit 1 for five common allergy treatments are noted below Intranasal
cromolyn (<=2 weeks from Visit 1). Intranasal or systemic decongestants (<=3 days from
Visit 1). Intranasal or systemic (other than oral) antihistamines (<=3 days from Visit
1).

Leukotriene modifiers (<=3 days from Visit 1). Oral antihistamines (<=2 days from Visit 1).
Allergy medications, other than study supplied medications, are not allowed during the
study.

- Use of other medications that may affect allergic rhinitis or its symptoms, e.g., use
of any ocular antihistamines, artificial tears, eyewashes/nasal irrigation solutions,
homeopathic preparations, lubricants, sympathomimetic or vasoconstrictor preparations
during the screening and treatment periods

- Use of any medications (prescription or non-prescription) or alcohol to induce sleep
48-hours prior to Visit 1 and during the treatment period.

- Use of other intranasally administered medications (e.g., calcitonin), including
herbals and homeopathics during the run-in (Visit 1 - Visit 2) and treatment period.

- Use of immunosuppressive medications within 8 weeks prior to screening and during the
treatment period.

- Use of any medications that significantly inhibit the cytochrome P450 subfamily enzyme
CYP3A4 (e.g., ritonavir, ketoconazole) during the run-in (Visit 1 - Visit 2) and
treatment period.

- Known hypersensitivity to corticosteroids or any excipients present in the nasal
spray.

- Known hypersensitivity to cetirizine or any excipients in the tablet.

- Recent exposure to an investigational study drug or device within 30 days of Visit 1.

coordinators, employees of a participating investigator or immediate family members of
the aforementioned are excluded from participating in this study.

- Chickenpox or measles during the last 3 weeks prior to screening and is non-immune.

dose will remain fixed for the duration of the study.

- Drug/alcohol abuse: Subjects with a known or suspected history of alcohol or drug
abuse within the last 2 years which in the opinion of the investigator could interfere
with the subject's proper completion of the protocol requirement.
