Trial Outcomes & Findings for SB705498 Proof of Concept Chamber Challenge in Subjects With Non Allergic Rhinitis (NCT NCT01424514)

NCT ID: NCT01424514

Last Updated: 2018-01-29

Results Overview

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.

PRIMARY outcome

Timeframe: Day 14 to Day 15 of each period (Day 14, 24 h post- dose was done on Day 15)

Population: All Subjects population defined as all participants who received at least one dose of study medication. Only those participants available at the specified time points were analyzed.

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.

Timeframe: Day 7 to Day 14 of each period

Population: All Subjects Population. Only those participants available at the specified time points were analyzed.

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.

Population: All Subjects Population. Only those participants available at the specified time points were analyzed.

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.

Population: All Subjects Population. Only those participants available at the specified time points were analyzed.

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.

Population: All Subjects Population. Only those participants available at the specified time points were analyzed.

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.

Timeframe: Pre-dose (0 h), 1, 2, 3 and 24 h post-dose on Day 1 and Day 14 of each period.

Population: Analysis was done on Pharmacokinetic Population, defined as participants in the 'All Subjects' population for whom a pharmacokinetic sample was obtained and analysed. Imputed NC values were derived for AUC (0-3), on Day 1 for 3 participants and for AUC (0-t) on Day 1 for 2 participants.

Blood samples for pharmacokinetic assessment were collected at pre-dose (0 h), 1, 2, 3 and 24 h post-dose on Day 1 and Day 14 of each period. The area under the plasma concentration-time curves from time zero (pre- dose) to 3 h, AUC (0-3) and the last quantifiable concentration, AUC (0-t) (24 h) was determined using the linear trapezoidal rule for increasing concentrations and the logarithmic trapezoidal rule for decreasing concentrations. The AUC of non-calculable (NC) due to non-quantifiable concentration measured as below lower limit of quantification (NQ) values were imputed by 0.5 x lowest observed AUC (i.e., AUC \[0-3\]: 0.5 x 6.4; AUC\[0-t\]: 0.5 x 6.3). Coefficient of variation (CVb \[%\]) was calculated as, CVb (%) = SQRT (exp \[SD2-1\]) x 100, where SQRT is the square root, exp is the exponent and SD is the standard deviation of the logarithmically transformed data. Analysis was done on the number of participants with non-missing observations (including imputed NC values).

AEs were classified as potentially drug-related, based on the investigator's judgement.

ECGs were obtained on Day 1 (pre-dose) and Day 14 (pre- dose) of each period. Single 12-lead ECGs was obtained at each timepoint during the study using an ECG machine that automatically calculated the heart rate (HR) and measures PR, QRS, QT, and QTc intervals. Participants with abnormal (not clinically significant), abnormal (clinically significant) and no result were presented.
