History of significant multiple and/or severe allergies, as assessed by the investigator, that would potentially interfere with the assessments during the baseline and 12-week efficacy assessment periods or confound results, per investigator discretion, including significant rhinitis or sinusitis due to daily contact with other allergens causing symptoms that are expected to coincide with the baseline period or any of the efficacy assessment periods
