  1. Additional Benefit of Montelukast in Patients with Both Asthma and Allergic Rhinitis Analysis from the COMPACT Trial Price DB1, Swern AS2, Tozzi CA2, Philip G2, Polos P2, Yu Q2 Originally presented at the World Allergy Organization Congress (XVIII ICACI), Vancouver, BC, Canada - September 10, 2003 Abstract published in Allergy & Clinical Immunology International 2003, Suppl. 1:29 abstract O-15-1 1 General Practice and Primary Care, University of Aberdeen, Aberdeen, UK 2 Merck & Co., Inc., Rahway, New Jersey, USA

  2. Clinical Observation of Montelukast as a Partner Agent for Complementary Therapy Price DB, Hernandez D, Magyar P et al. Thorax 2003;58:211-216

  3. Background • Asthma and allergic rhinitis frequently coexist1 • Rhinitis occurs in 75% of patients with allergic asthma and 80% of patients with non-allergic asthma • The same triggers (e.g., allergens) can cause rhinitis and asthma • Actively treated rhinitis is a risk factor for asthma exacerbations1 • Upper and lower airways share a common & probably interconnected inflammatory process • Common inflammatory cells: mast cells, eosinophils, T-cells2 • Common inflammatory mediators: histamine, leukotrienes, cytokines3 • Bronchial challenge leads to nasal inflammation, and nasal challenge leads to bronchial inflammation3 1.

  4. Background • Optimal management of rhinitis may improve coexisting asthma1 • Montelukast is approved to treat asthma and recently has gained approval for allergic rhinitis in several countries • Argentina, Czech Republic, Mexico, New Zealand, United States, etc. 1. Bousquet J and the ARIA Workshop Group J Allergy Clin Immunol 2001;108(5):S147-S334

  5. COMPACT Study Objectives To determine the effect of: • Adding montelukast to inhaled budesonide 800 mg daily versus • Doubling the dose of inhaled budesonide from 800 mg daily to 1600 mg daily

  6. Inclusion Criteria for COMPACTStudy • Adults (15 to 70 years) with chronic asthma for >1 year • Using inhaled corticosteroids for >12 weeks • Dose range: 600 to 1200 µg/day (of BDP or equivalent) • Asthma not optimally controlled (judged by investigator) • Baseline FEV1 or PEF value >50% predicted • -agonist reversibility • >12% in FEV1 or >15% in PEF at randomisation visit, or • Predefined PEF variability >20% • Minimal level of daytime symptoms and b-agonist use during the 2 weeks pre-randomisation

  7. Period II Active treatment (12 weeks) Double-blind Period IRun-in (4 weeks) Single-blind n=448 Montelukast 10 mg once daily + Budesonide 400 µg twice daily Budesonide 400 µg twice daily Budesonide 800 µg twice daily n=441 0 1 4 16 8 12 Weeks Study Design

  8. Objective of this Analysis • To determine if treatment with montelukast added to budesonide (400 g twice daily), compared with budesonide (800 g twice daily), provides additional benefit to patients with co-existing asthma and allergic rhinitis

  9. Statistical Analysis • All patients with a baseline and at least one on-treatment value were included in this intention-to-treat analysis • Treatment comparisons were based on an analysis of covariance (ANCOVA) model, with corresponding baseline value included as a covariate and treatment group as a factor • All analyses of patient subgroups were post hoc

  10. Definition of Groups in Analysis • Asthma+AR Patients with asthma and allergic rhinitis, defined by both positive patient history and confirmed physician diagnosis • Asthma–AR Patients with asthma but without both a patient history and physician diagnosis of allergic rhinitis

  19. Change in AM PEFAsthma+AR Patients: Using Rhinitis Meds§ § Intranasal steroids or antihistamines or other treatments for rhinitis * Montelukast 10 mg once-daily along with budesonide 400 g twice-daily. ** Budesonide 800 g twice-daily

  20. Percent Increase in AM PEFin Different AR Subgroups Percentages calculated using LS mean for change and baseline mean § Intranasal steroids or antihistamines or other treatments for rhinitis * Montelukast 10 mg once-daily along with budesonide 400 g twice-daily. ** Budesonide 800 g twice-daily

  21. Results • Adding montelukast significantly improved AM PEF in patients who had both asthma and allergic rhinitis (defined by both patient history and physician diagnosis), versus doubling the dose of inhaled budesonide • Treatment effect was greatest in patients taking medications for rhinitis at randomization • Doubling the dose of budesonide was less effective for asthma than adding montelukast in patients with both allergic rhinitis and asthma • Patients with both allergic rhinitis and asthma – who were also taking medications for rhinitis – showed minimal improvement in AM PEF with doubling the budesonide dose

  22. Conclusion • In the subgroup ofpatients from the COMPACT study who had both asthma and allergic rhinitis, adding montelukast to budesonide provided greater benefit in reducing airflow obstruction, compared with doubling the dose of budesonide
