Safety and dose finding study based on the effects of three subcutaneous injections of BM32, a recombinant hypoallergenic grass pollen vaccine, on responses to allergen challenge by skin testing and in the Vienna Challenge Chamber (VCC) as well as immunological responses in subjects known to suffer from grass pollen- induced allergic rhinitis. A prospective, randomised, double- blind, placebo-controlled, parallel group evaluation.

Healthy subjects are defined as individuals who are free from clinically significant illness or disease as determined by their medical history (including family), physical examination, laboratory studies, and other tests deemed by the Investigator or designee.
•?Male or female between 18 and 60 years of age inclusive, at the time of signing the informed consent. They have a history of seasonal allergic rhinitis (SAR) to grass pollen.
•?They have a normal electrocardiogram without clinically significant abnormalities deemed by the Investigator or designee.
•?They exhibit a moderate to severe response to approximately 1500 grass pollen grains/m3 after the first 2h in the Vienna Challenge Chamber, which is defined as a nasal symptom Score (TNSS) of at least 6\. (Nasal symptom Score is the sum of nasal obstruction, rhinorrhoea, itchy nose and sneezing, each of which have been Scored on a scale from 0 to 3\).
•?They have a positive skin prick test (wheal diameter ? 3mm) for grass pollen at or within 12 months preceding the screening visit.
•?They have a positive RAST (class greater/equal 2\) for timothy grass pollen (g6\) and to rPhl p 1\+rPhl p 5 at or within 12 months preceding the screening visit.
•?There are no conditions or factors which would make the subject unlikely to be able to stay in the chamber for 6 hours.
•?They are capable of giving informed consent which includes compliance with the requirements and restrictions listed in the consent form.
•?They are available to complete all study measurements
•Are the trial subjects under 18? no

Exclusion Criteria

•?Pregnant, lactating or sexually active women with childbearing potential who are not using a medically accepted birth control method (pregnancy to be controlled by a pregnancy dipstick test).
•?On examination the subject is found to have any structural nasal abnormalities or nasal polyposis, a history of frequent nosebleeds, recent nasal surgery or ongoing upper respiratory tract infection which in the Responsible Physician’s opinion renders the subject unsuitable for participation in the study.
•?Any respiratory disease other than mild stable asthma that is controlled with occasional use of as\-needed short\-acting beta\-agonists and associated with normal lung function.
•?The subject is concurrently participating or has participated in any clinical study in the previous month.
•?The subject has received SIT for grass pollen allergy in the last two years prior to this study.
•?Past or present disease, which as judged by the investigator, may affect the outcome of this study.
•?autoimmune diseases, immune defects including immuno\-suppression, immune\-complex\-induced immunopathies
•?Suspected hypersensitivity to any ingredients of the study medication
•?Use of prohibited medication prior to Screening and throughout the study:
•oDepot corticosteroids – 12 weeks
