排除标准
- •1. Pre-bronchodilator FEV1 less than 70% of predicted value at screening visit
- •2. A history of seasonal grass pollen-induced asthma requiring regular treatment with salbutamol or inhaled corticosteroids. Patients with mild seasonal grass pollen-induced asthma may be included, provided symptoms are satisfactorily controlled with occasional salbutamol only.
- •3. A clinical history of symptomatic seasonal allergic rhinitis and/or asthma due to tree pollen or weed pollen near or overlapping the grass pollen season.
- •4. A clinical history of symptomatic allergic rhinitis and/or asthma caused by a perennial allergen to which the participant is regularly exposed.
- •5. Emergency department visit or hospital admission for asthma in the previous 12 months.
- •6. History of chronic obstructive pulmonary disease.
- •7. History of significant recurrent acute sinusitis, defined as 2 episodes per year for the last 2 years, all of which required antibiotic treatment.
- •8. History of chronic sinusitis, defined as a sinus symptoms lasting greater than 12 weeks that includes 2 or more major factors or 1 major factor and 2 minor factors. Major factors are defined as facial pain or pressure, nasal obstruction or blockage, nasal discharge or purulence or discoloured postnasal discharge, purulence in nasal cavity, or impaired or loss of smell. Minor factors are defined as headache, fever, halitosis, fatigue, dental pain, cough, and ear pain, pressure, or fullness.
- •9. At randomisation, current symptoms of, or treatment for, upper respiratory tract infection, acute sinusitis, acute otitis media, or other relevant infectious process; serous otitis media is not an exclusion criterion. Participants may be re-evaluated for eligibility after symptoms resolve
- •10. Current smokers or a history of greater than or equal to 5 pack years
- •11. Previous treatment by immunotherapy with grass pollen allergen within the previous 5 years
- •12. History of life-threatening anaphylaxis or angioedema
- •13. Ongoing systemic immunosuppressive treatment
- •14. History of intolerance of grass pollen immunotherapy, rescue medications or their excipients
- •15. For females of childbearing age a positive serum or urine pregnancy test with sensitivity of less than 50 mIU/mL within 72 hours of first administration of study therapy
- •16. Lactating females
- •17. The use of any investigational drug within 30 days of the screening visit
- •18. Ongoing treatment with beta-blockers, calcium channel blockers, tricyclic antidepressants, monoamine oxidase inhibitors or anti-IgE monoclonal antibody
