Study design
• Sinusitis is a frequent disease with an increasing prevalence. In Germany chronic sinusitis has been diagnosed 2.6 million times within a one- year period (July 2000 until This was a phase-III, randomized, placebo-controlled, double-blind, parallel -group, multicenter clinical trial in 60 patients. The study protocol was approved of by independent ethics committees. All patients were required to give their informed consent • It has been proven in a recent study that a monotherapy with a topically applied corticosteroid (budesonide aqueous nasal spray) is efficacious in the treatment of chronic sinusitis.7 Patients with the clinical diagnosis of a chronic sinusitis and a positive CT-scan (Lund-Scale 2- 10) with an opacification of at least one osteomeatal complex and a moderate • Mometasone furoate nasal spray (MFNS) is being investigated for the treatment of or severe nasal obstruction were randomized to receive either MFNS solution (200 mcg chronic sinusitis.

Patients were required to visit the physician six times over the study period.
• the treatment of allergic rhinitis.
Subjects
• In previous studies corticosteroids, in particular MFNS, have been proven to be efficacious as an adjunctive treatment to antibiotics in patients with acute sinusitis.6 Between April and September 2003, 60 patients (30 per group) with a history of chronic sinusitis for at least 3 months up to 35 years were randomized to treatment. The • A comparison of several intranasal steroids concedes that mometasone furoate has intention-to-treat population consisted of 45 patients; the per -protocol population the lowest systemic availability. 3, 4, 5 Less than 0.1 % of the dose is absorbed into the Endpoints
Objectives
The primary efficacy endpoint was the change from baseline in the all day sum score
To evaluate the efficacy and safety of 200 mcg BID mometasone furoate nasal spray of the Total Sinusitis Symptom Score (TSS) as recorded in the patient diaries over the

112 days of treatment. The baseline TSS was defined as the sum of the a.m. and the p.m. score on Day 1, prior to taking the first dose of study medication The patients used a 4-point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe). The single symptoms assessed were: Analysis
• anterior rhinorrhea• postnasal drip according top the intention-to-treat-principle. A complementary analysis was perfomed on the per -protocol -population for the main endpoint only. Treatment groups were compared with respect to the baseline TSS using the Wilcoxon-Mann- Withney test, and also with respect to the secondaryendpoints at baseline using the adequate tests respectively. Secondary efficacy parameters
• Individual symptoms and global evaluation of sinusitis
• Endoscopical appearance score of the sinusitis

Tolerability
Conclusion
The tolerability of the medication was excellent. One patient in each group left the study This is the first long -term study on the use of mometasone furoate nasal spray in due to an adverse event: pruritus in the verum group and epistaxis in the placebo patients with CT- documented chronic sinusitis. During the course of symptoms over group. The most frequently observed AE was epistaxis, which at 10% fell into the four months of treatment, a clear numerical superiority of the nasal spray containing expected range and occurred at almost the same rate under verum and placebo.
the active ingredient can be noted which also reaches statistical significance on individual days. That this concerns clinically relevant advantag es is reflected in the positive final assessment made by the patients treated with MFNS. Affrime MB, Kosoglou T, Thonoor CM, Flannery BE, Herron JM.
