Trial Outcomes & Findings for A Study to Compare the Efficacy and Safety of Fluticasone Furoate Nasal Sprays (FFNS) 55 Microgram (mcg) and 110 mcg in Chinese Pediatric Subjects With Allergic Rhinitis (AR) (NCT NCT02424539)

This efficacy and safety study of fluticasone furoate (FF) was conducted at 16 centers in China. A total of 505 pediatric participants with allergic rhinitis were screened; of which 147 were screen and run-in failures and 358 were randomized in a 1:1:1 ratio to receive placebo, FF 55 micrograms (µg) or FF 110 µg once daily (QD).

TNSS is a composite score of the four components (nasal congestion, itching, rhinorrhea and sneezing) with a total score of 0 to 12. A higher score means a worse nasal symptom. The score of each component ranges from 0 (no symptom) to 3 (severe symptoms). Participants were instructed to provide scores in a reflective manner using their diary. The daily rTNSS was the average of the morning rTNSS and evening rTNSS assessments. The daily scores were averaged to calculate the overall/total score. The morning reflective assessment was performed prior to administering the morning dose. The evening reflective assessment was performed approximately 12 hours after dosing but before bedtime. Baseline scores obtained over "4 days prior to randomization" were average of the last 8 rTNSS assessments (4 AM assessments, 4 PM assessments) over the consecutive four 24-hours periods prior to randomization. Change from Baseline was defined as post-dose visit value minus Baseline value.

Response was defined as effectiveness of study medication for relieving allergic rhinitis symptoms over the entire treatment period. Overall response to therapy was evaluated using the 7-point categorical scale ranging from 1 (significantly improved) to 7 (significantly worse). Number of participants showing response to therapy after the first 2 weeks have been presented. Only those participants with response to therapy over the entire treatment period were included in the analysis.

The nasal concha mucosa symptoms score was used to evaluate change in anterior rhinoscopy. It is a composite score of four components including swelling of inferior nasal concha mucosa, color of inferior nasal concha mucosa, watery secretion volume and description of rhinorrhea. Severity of each of the component was assessed using the scale ranging from 0 (no symptom) to 3 (severe). The 4 components were averaged to obtain a total score which ranges from 0 to 12 where a higher score means a worse nasal symptom. Baseline was defined as 4 days prior to randomization, including the morning symptom assessment on the randomization date. Change from Baseline was defined as post-dose visit value minus Baseline value. Only those participants with data available at the specified time points were included in the analysis.

TOSS is a composite score of the three components (eye itching and burning, eye watering and eye redness) with a total score of 0 to 9. Higher score means a worse symptom. The score of each component ranges from 0 (no symptom) to 3 (severe symptoms). The daily scores were averaged to calculate the overall/total score. Participants were instructed to provide scores and document their symptoms in a reflective manner twice daily using their diary at the same time of reflective nasal symptoms assessment. Baseline scores obtained over "4 days prior to randomization" were average of the last 8 rTNSS assessments (4 AM assessments, 4 PM assessments) over the consecutive four 24-hours periods prior to randomization. Change from Baseline was defined as post-dose visit value minus Baseline value

Loratadine was provided as a rescue medication to use if needed throughout the study treatment period. Participants were asked to document loratadine rescue medication use on the daily treatment diary. Baseline was defined as 4 days prior to randomization, including the morning symptom assessment on the randomization date. Change from Baseline was defined as post-dose visit value minus Baseline value.

An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability, is a congenital anomaly/birth defect, other situations and is associated with liver injury or impaired liver function.

Blood samples were collected from participants at indicated time points to evaluate clinical chemistry values outside normal range. The clinical chemistry parameters including alanine aminotransferase (ALT), albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), calcium, creatinine, direct bilirubin, glucose, potassium, sodium, total bilirubin, total protein and blood urea nitrogen (BUN) with values outside normal range is presented.

A detailed nasal examination of the mucosa, septum, secretions, nasal patency, size of any polyps and ulcers was performed at specific time points. Number of participants with improved or worsened conditions are presented. Improved condition was defined as increase in number of patencies and Worsened condition was defined as decrease in number of patencies, from Baseline to Week 4.
