ListOutcomeTime frameDescription
PrimaryMean Total Symptom Score (TSS) Elicited by a 1 Hour (h) Cold Dry Air (CDA) Challenge, 1 h and 24 h on Day 14 to Compare the Effect of 14 Day Repeat Dosing of Intranasal SB-705498 12 mg With PlaceboDay 14 to Day 15 of each period (Day 14, 24 h post- dose was done on Day 15)
TSS was calculated based on a CDA challenge, done for 1 h in a controlled environmental exposure chamber which was validated for 14+/-5 degree Celsius (C), \<15% relative humidity and 5+/-3 feet per second (ft/sec) air velocity, 1 h and 24 h post dose on Day 14 (Day 15). TSS was calculated as the sum of the response for 3 components of nasal congestion, rhinorrhoea and post nasal drip. It was rated on a 4-point scale ranging from 0 to 3, where: 0=absent, 1=mild, 2=moderate, and 3=severe (symptom hard to tolerate). TSS score ranges from 0-9 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. Weighted mean (WM) for TSS was calculated over the time interval 0 to 60 minute (m) after start of CDA challenge by calculating area under the curve (AUC) of the TSS via the linear trapezoidal method then dividing by the total duration that the participant took to complete CDA challenge assessments. WM is reported as least square (LS) mean.

Day 14 to Day 15 of each period (Day 14, 24 h post- dose was done on Day 15)
The individual components of TSS was calculated based on a CDA challenge, done for 1 h in a controlled environmental exposure chamber which was validated for 14+/-5 degree C, \<15% relative humidity and 5+/-3 ft/sec air velocity, 1 h and 24 h post dose on Day 14 (Day 15). The individual component of TSS nasal symptoms were nasal congestion, rhinorrhoea (runny nose), and post nasal drip It was rated on a 4-point scale ranging from 0 to 3, where: 0=absent, 1=mild, 2=moderate, and 3=severe (symptom hard to tolerate). The scores of the individual components of TSS ranges from 0-3 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. WM for TSS was calculated over the time interval 0 to 60 m after start of CDA challenge by calculating AUC of the TSS via the linear trapezoidal method then dividing by the total duration that the participant took to complete CDA challenge assessments. WM is reported as LS mean.

The individual component of TSS nasal symptoms were nasal congestion, rhinorrhoea (runny nose), and post nasal drip It was rated on a 4-point scale ranging from 0 to 3, where: 0=absent, 1=mild, 2=moderate, and 3=severe (symptom hard to tolerate). The score ranges from 0-3 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. WM for TSS was calculated over the time interval 0 to 60 m after start of CDA challenge by calculating AUC of the TSS via the linear trapezoidal method then dividing by the total duration that the participant took to complete CDA challenge assessments. WM is reported as LS mean.
SecondaryMean TSS From Day 7 to Day 14 (Post-dose Prior to Challenge) Following Repeat Doses of SB-705498Day 7 to Day 14 of each period
TSS was calculated as the sum of the response for 3 components of nasal congestion, rhinorrhoea and post nasal drip. It was rated on a 4-point scale ranging from 0 to 3, where: 0=absent, 1=mild, 2=moderate, and 3=severe (symptom hard to tolerate). TSS score ranges from 0-9 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. For Day 1 to 14 of each study period, participants were asked to keep a diary to record their symptoms whilst at home provided by the clinical unit. Reflective rating represented the symptoms over the proceeding 12 h which was performed once daily in the evening (PM). The PM reflective rating was done approximately 12 h after dosing, but before bedtime. If any of the individual components were missing then the TSS was set to be missing for that participant at that timepoint.
SecondaryMean Individual Component of TSS of Rhinorrhoea (Runny Nose), Nasal Congestion and Post-nasal Drip From Day 7 to Day 14 Following Repeat Doses of SB-705498Day 7 to Day 14 of each period
The individual component of TSS nasal symptoms of nasal congestion, rhinorrhoea (runny nose) and post nasal drip was scored on a 4-point scale ranging from 0 to 3, where: 0=absent, 1=mild, 2=moderate, and 3=severe (symptom hard to tolerate). The scores of the individual components of TSS ranges from 0-3 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. For Day 1 to 14 of each study period, participants were asked to keep a diary to record their symptoms whilst at home on a diary card provided by the clinical unit. Reflective rating represented the symptoms over the proceeding 12 h which was performed once daily in the PM. The PM reflective rating was done approximately 12 h after dosing, but before bedtime.
SecondaryMean Sneezing Elicited by a 1 h CDA Challenge at 1 h Post-dose on Day 1, 1 and 24 h Post-dose on Day 14 to Compare the Effect of Intranasal SB-705498 12 mg With PlaceboDay 1, Day 14 and Day 15 of each period (Day 14, 24 h post- dose was done on Day 15)
The assessment of sneezing was done based on a CDA challenge, for 1 h in a controlled environmental exposure chamber which was validated for 14+/-5 degree C, \<15% relative humidity and 5+/-3 ft/sec air velocity, 1 h post dose on Day 1 and 1 h and 24 h post dose on Day 14 (Day 15). Sneezing was scored on a 4-point scale ranging from 0 to 3, where: 0=absent, 1=mild, 2=moderate, and 3=severe (symptom hard to tolerate). The score ranges from 0-3 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. It was used to derive the WM CDA challenge value calculated over the time interval 0 to 60 m after start of CDA challenge and the maximum score. WM is reported as LS mean.
SecondaryMean Change From Baseline to Day 14 of Acoustic Rhinometry (AR) Following Repeat Dosing of SB-705498 at 2 h and 25 h Post-doseBaseline (Day 1 pre-dose), Day 14 and Day 15 of each period (Day 14, 25 h post dose on Day 14 was evaluated on Day 15)
Overall AR score was obtained by adding minimal cross-sectional area (MCA) for right and left nostril. MCA1 was captured within the nose at a distance of 0 and 2.2 cm and MCA2 at 2.2 and 5.5 cm. MCA1 and MCA2 were captured simultaneously for each nostril, 3 measurements were obtained from each nostril which resulted in 12 data points. Absolute MCA for all regions in left or right nostril was calculated using the 3 acceptable measurements, calculating average of each of right and left MCA's and also by selecting minimum value from these averages to obtain minimum MCA for left and right nostril. Baseline is defined as the value on Day 1 pre- dose. Change from baseline was calculated by subtracting the baseline (Day 1 pre-dose) values from individual post-randomization values done immediately following CDA challenge. In case of missing baseline or post randomization value, the change from baseline was set to be missing. Adjusted mean is reported as LS mean.
SecondaryMean Change From Baseline in Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) Following Repeat Doses of SB-705498 on Day 14Baseline (Day 1 pre-dose) and Day 14 of each period
The RQLQ is a 28-item, disease-specific quality of life questionnaire that measures the functional (physical, emotional, and social) problems troublesome to adults with allergies. The RQLQ has 28 questions in 7 domains (activities, sleep, non-nose/eye symptoms, practical problems, nasal symptoms, eye symptoms and emotional). All 28 questions were evaluated by the participant in an assessment diary over 2 weeks of treatment period and was rated on a 7-point severity scale ranging from 0 to 6, where 0=least severe to 6=extremely severe. Overall mean was calculated by summing all 28-item scores and dividing by total number of items in the questionnaire. RQLQ score ranges from 0-6 with 0 representing an absence of symptoms and higher scores reflecting more severe symptoms. Baseline was defined as the value on Day 1 pre- dose. Change from baseline was calculated by subtracting baseline (Day 1 pre-dose) values from individual post-randomization values. Adjusted mean is reported as LS mean.
Secondary
Mean Total Ocular Symptom Score (TOSS; Red, Itchy and Tearing Eyes) Elicited by a 1 h CDA Challenge at 1 h Post-dose on Day 1, 1 and 24 h Post-dose on Day 14 to Compare the Effect of Intranasal SB-705498 12 mg Compared With Placebo
Day 1 and 15 of each period (Day 14, 24 h post- dose was assessed on Day 15)
The assessment of TOSS was done based on a CDA challenge, for 1 h in a controlled environmental exposure chamber which was validated for 14+/-5 degree C, \<15% relative humidity and 5+/-3 ft/sec air velocity, 1 h post dose on Day 1 and 1 h and 24 h post dose on Day 14 (Day 15). TOSS was calculated as the sum of the symptom scores for 3 ocular symptoms of itching/burning eyes, tearing/watering eyes, and redness of eyes. It was rated on a 4-point severity scale ranging from 0 to 3, where: 0=absent, 1=mild, 2=moderate and 3=severe (symptom hard to tolerate, interferes with daily activities/sleeping). TOSS score ranges from 0-9 with 0 representing an absence of symptoms and 9 representing severe symptoms. These values were used to derive the WM (s) of the CDA challenge value and the maximum score. WM is reported as LS mean.
