Detailed Description
The study was performed at university clinics in Kharkiv and Dnepropetrovsk in Ukraine in May 2013. 108 subjects 18-40 years of age were recruited locally to 2 centres. They all had a history of typical symptoms of seasonal allergic rhinitis (SAR) during late spring - early summer. At first appointment the history was scrutinized and an assessment of the severity excluded previous use of nasal steroids or a current need for nasal steroids. They should not have perennial symptoms or a history of asthma. They were tested with a blood sample for ImmunoCAP Specific Immunoglobulin E (IgE) for timothy grass pollen and birch pollen, with >0.35 Kilounits (kU)/ml counted as positive.
The patients were randomly assigned to active or placebo in groups using an identical device to be puffed in each nostril 3 times daily. The nasal powders were supplied in plastic containers, which deliver the powder from a nozzle when squeezed. The exact amount delivered is not standardized and the variations of patterns of deposition in the nose are not known. The placebo was a lactose powder with the same particle size, appearance and the same tinge of mint taste as the cellulose powder.
Rescue medication could be obtained by the investigators after emergency contacts. Oral antihistamine was loratadine 10 mg tablets and sodium chromoglycate eye drops. Each subject obtained oral and written instructions about the SMS. The SMS-reporting of symptoms started with a run in period for 3 days before the treatment and lasted for the 4 weeks of treatment during the grass pollen season
Three times a day the patients were reminded by SMS to take their nasal puffs and were asked to confirm the intake by a response SMS. In the evening, they were asked about the severity of symptoms during the preceding day from the nose, eyes and lower airways and to answer with a figure 1-6, corresponding to 1 "no trouble at all", 2"little trouble", 3"moderate trouble", 4"rather much trouble", 5"much trouble", and 6 "very much trouble" respectively. From the nose, scoring of sneezing, running nose and blocked nose were reported. For the eyes and lower airways, respectively, only a concluding figure was used.
In the registration a question was added daily on the use of rescue medication.
At a concluding appointment after the treatment period, the subjects were asked about their global opinion of the efficacy: No effect, good effect, very good effect. They also were asked whether they believed they had obtained the active substance or placebo.

Statistical methods For each question the mean score was calculated for the whole 28 days period for every subject. Mean values for the sum of all scores as well as the sum of the nasal scores were also calculated. The scores from the two treatment groups were then compared using t-tests. The group comparison of reflective opinions and the guess on obtained medication at the follow up visit were assessed using the Chi-square test.
The concluding opinion at the follow up visit were analysed using the chi-square test.
The study was approved by the local ethics committees at the respective hospitals.

The patients were randomly assigned to active (Nasaleze cellulose powder) or placebo groups using an identical device to be puffed in each nostril 3 times daily.
The nasal powders were supplied in plastic containers, which deliver the powder from a nozzle when squeezed.
The exact amount delivered is not standardized and the variation in the patterns of deposition in the nose is not known.
The placebo was a lactose powder with the same particle size, appearance and the same tinge of mint taste as the cellulose powder.
