入选标准
- •Male or female patients 12 years of age and older, as of the Screening Visit (SV).
- •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 study.
- •A history of SAR to relevant seasonal allergen (tree/grass pollen) for a minimum of two years immediately preceding the study Screening Visit (SV). The SAR must have been of sufficient severity to have required treatment (either continuous or intermittent) in the past and in the investigator's judgment is expected to be exposed to the allergen and require treatment throughout the entire study period.
- •A demonstrated sensitivity to relevant tree/grass pollen known to produce SAR through a standard skin prick test. A positive test is defined as a wheal diameter at least 3 mm larger than the control wheal for the skin prick test. Documentation of a positive result within 12 months prior to Screening Visit (SV) is acceptable.
- •Other criteria apply
排除标准
- •Participation in any investigational drug study within the 30 days preceding the Screening Visit (SV) or planned participation in another investigational drug study at any time during this study.
- •History of physical findings of nasal pathology, including nasal polyps or other clinically significant respiratory tract malformations, recent nasal biopsy, nasal trauma or surgery, atrophic rhinitis, or rhinitis medicamentosa (all within the last 60 days prior to the SV).
- •History of a respiratory infection or disorder [including, but not limited to bronchitis, pneumonia, chronic sinusitis, influenza, severe acute respiratory syndrome (SARS)] within the 14 days preceding the Screening Visit (SV), or development of a respiratory infection during the Run-in Period.
- •Use of any prohibited concomitant medications within the prescribed (per protocol) time since the last dosing period prior to the Screening Visit (SV) and/or plans for use during the entire treatment duration.
- •Other criteria apply
研究组 & 干预措施
Placebo

干预措施: Placebo (Drug)
BDP HFA 80 µg/day
During the 2-week double-blind Treatment Period participants self-administered two actuations (one per nostril) of 40 micrograms (µg) BDP HFA and two actuations of placebo HFA once daily.
干预措施: Beclomethasone dipropionate HFA Nasal Aerosol (Drug)
BDP HFA 80 µg/day
During the 2-week double-blind Treatment Period participants self-administered two actuations (one per nostril) of 40 micrograms (µg) BDP HFA and two actuations of placebo HFA once daily.
干预措施: Placebo (Drug)
BDP HFA 160 µg/day
During the 2-week double-blind Treatment Period participants self-administered four actuations (two per nostril) of 40 µg BDP HFA once daily.
干预措施: Beclomethasone dipropionate HFA Nasal Aerosol (Drug)
BDP HFA 320 µg/day
During the 2-week double-blind Treatment Period participants self-administered 4 actuations (two per nostril) of 80 µg BDP HFA once daily.
干预措施: Beclomethasone dipropionate HFA Nasal Aerosol (Drug)
结局指标
主要结局
Change From Baseline in Average AM and PM Reflective Total Nasal Symptom Score (rTNSS) Over the Two-week Treatment Period
时间窗: Baseline (Day -6 to 0) and Days 1-15 (2-week Treatment Period)
Participants recorded the severity of their nasal symptoms (sneezing, runny nose, itchy nose and nasal congestion) over the past 12 hours twice daily (AM \& PM) using the following scale: 0=absent (no sign/symptom); 1=mild (sign/symptom present, easily tolerated); 2=moderate (awareness of sign/symptom, bothersome but tolerable); 3=severe (sign/symptoms hard to tolerate, interfere with daily activities and/or sleeping). The total nasal symptom score (sum of the 4 symptom scores) ranges from 0 to 12 (worst symptoms). A negative change from Baseline score indicates symptom improvement.
次要结局
- Change From Baseline in Average AM and PM Instantaneous Total Nasal Symptom Score (iTNSS) Over the Two Week Treatment Period(Baseline (Day -6 to 0) and Days 1-15 (2-week Treatment Period))
- Change From Baseline in Morning Instantaneous Total Nasal Symptom Score (iTNSS) Over the Two-week Treatment Period(Baseline (Day -6 to 0) and Days 1-15 (2-week Treatment Period))
- Change From Baseline in Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)(Baseline and Week 2)
- Change From Baseline in Morning 24-hour Reflective Ocular Symptom Score Over the Two-week Treatment Period(Baseline (Day -6 to 0) and Days 1-15 (2-week Treatment Period))
- Change From Baseline in Morning 24-hour Reflective Non-nasal Symptom Score Over the Two-week Treatment Period(Baseline (Day -6 to 0) and Days 1-15 (2-week Treatment Period))
