Weighted Mean TNSS (Sneeze, Itch, Rhinorrhoea and Nasal Blockage) 1-6 Hours Post Start of Allergen Challenge (2-7 Hours Post-dose) on Day 3
On the third dosing day, participants entered the ECC for a duration of 6 hours, 1 hour after receiving their third dose. Time 0 hour was considered as the time that the participant entered the ECC. Nasal blockage, itch, sneeze and rhinorrhoea was scored on a categorical scale from 0 to 3 (0: no symptoms; 1: mild symptoms; 2: moderate symptoms; 3: severe symptoms). The total TNSS ranged from 0-12 point, with low score indicates well-being and higher score indicates more severity. Individual symptoms scores was summed at each time point (0, 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340 and 360 minutes). The adjusted mean is provided as least square mean.
Time frame: Day 3 of each treatment period (approximately up to 63 days)
Weighted Mean of the Individual Components of TNSS (Sneeze, Itch, Rhinorrhoea and Nasal Blockage) 1-6 Hours Post Start of Allergen Challenge (2-7 Hours Post-dose) on Day 3
On the third dosing day, participants entered the ECC for a duration of 6 hours, 1 hour after receiving their third dose. Time 0 hour was considered as the time that the participant entered the ECC. Nasal blockage, itch, sneeze and rhinorrhoea was scored on a categorical scale from 0 to 3 (0: no symptoms; 1: mild symptoms; 2: moderate symptoms; 3: severe symptoms). The total TNSS ranged from 0-12 point, with low score indicates well-being and higher score indicates more severity. Individual symptoms scores was summed to produce the TNSS at each time point (0, 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340 and 360 minutes). The adjusted mean is provided as least square mean.
Time frame: Day 3 of each treatment period (approximately up to 63 days)
Weighted Mean Wet Tissue Weight (as a Surrogate Marker of Nasal Secretion) 1-6 Hours Post Start of Allergen Challenge (2-7 Hours Post-dose) on Day 3
On the third dosing day, participants entered the ECC for a duration of 6 hours, 1 hour after receiving their third dose. Time 0 hour was considered as the time that the participant entered the ECC. Wet tissue weight assessments was measured as a surrogate marker of nasal secretion at 60, 120, 180, 240, 300 and 360 minutes. The adjusted mean is provided as least square mean.

Weighted Mean Nasal Congestion VAS 1-6 Hours Post Start of Allergen Challenge (2-7 Hours Post-dose) on Day 3
On the third dosing day, participants entered the ECC for a duration of 6 hours, 1 hour after receiving their third dose. Time 0 hour was considered as the time that the participant entered the ECC. Nasal congestion was measured on 0-10 centimeter VAS scale (0: no symptoms and 10: the worst possible symptoms) with low score indicates well-being and higher values indicate greater congestion. It was measured at 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340 and 360 minutes. The adjusted mean is provided as least square mean.
Time frame: Day 3 of each treatment period (approximately up to 63 days)
Mean Forced Expiratory Volume in 1 Second (FEV1)
On the third dosing day, participants entered the ECC for a duration of 6 hours, 1 hour after receiving their third dose. Time 0 hour was considered as the time that the participant entered the ECC. FEV1 was measured at pre-challenge, 60, 120, 180, 240, 300 and 360 minutes.
Time frame: Day 3 of each treatment period (approximately up to 63 days)
Number of Participants With Adverse Events (AE) and Serious Adverse Events (SAE)
An AE was defined as any untoward medical occurrence (MO) in a participant temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP and can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with its use. The SAE was any untoward MO that, at any dose, results in death, life threatening, persistent or significant disability/incapacity, results in or prolongs inpatient hospitalization, congenital abnormality or birth defect, that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention or is associated with liver injury and impaired liver function defined as: alanine aminotransferase \>=3 times upper limit of normal (ULN), and total bilirubin \>=2 times ULN or international normalized ratio more than 1.5.
Time frame: approximately up to 63 days
