E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
This is a Phase II trial (Proof of Principle) in volunteer rhinitis subjects utilising a seasonal model of rhinitis and challenge agent |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to explore the efficacy of AZD3778 compared with placebo and an oral antihistamine, Loratadine, in relieving the symptoms of allergic rhinitis in a model of seasonal allergic rhinitis by assessment of subjects’ subjective nasal symptom scores and nasal peak inspiratory flow.
|
|
E.2.2 | Secondary objectives of the trial |
To assess the safety and tolerability of AZD3778 by assessment of the incidence and nature of adverse events, effects on ECG, vital signs and laboratory asessments
To evaluate drug exposure by measurement of plasma concentrations of AZD3778
To perform exploratory analysis on effects of AZD3778 on inflammatory markers in nasal tissue and nasal lavage (collected before and after provocation with bradykinin).
To collect pharmacogenetic samples for possible retrospective exploratory analysis, to investigate the influence of genotype on safety, pharmacokinetics and pharmacodymanic response associated with AZD3778 and its target receptors (optional part of this study) |

E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
For inclusion in the study subjects must fulfil all of the following criteria: 1. Be willing and able to comply with study procedures and provide informed consent 2. Men and post-menopausal or surgically sterilised women aged 18 to 60 years inclusive, (women will be considered post-menopausal if they have been amenorrheic for 12 months and FSH plasma concentration is within the post menopausal range as defined by the laboratory) 3. A clinical diagnosis of birch and/or timothy grass pollen induced seasonal allergic rhinitis for at least the previous 2 years 4. The presence of allergic sensitivity to birch and /or timothy grass pollen verified by a positive skin prick test documented within the previous 24 months or at Visit 1 5. Asymptomatic subjects out of season, as judged by the investigator 6. Subjects with need of treatment for their nasal symptoms during the pollen season 7. Reaction to a nasal allergen challenge resulting in at least five sneezes and/or recorded score of ≥ 2 on a scale from 0-3 in either of the symptoms nasal blockage and/or runny nose
For inclusion in the genetic part of the study the subjects must fulfil the following criterion: 1. Provision of informed consent for genetic research
If a subject declines to participate in the genetic research, there will be no penalty or loss of benefit to the subject. The subject will not be excluded from other aspects of the study described in this Clinical Study Protocol, so long as they consent.

E.4 | Principal exclusion criteria |
Any of the following is regarded as a criterion for exclusion from the study: 1. Any clinically relevant disease and /or abnormality which in the opinion of the investigator, either put the subject at risk because of participation in the study or influence the results of the study or the subjects ability to participate in the study. 2. Subjects with structural abnormalities of the nose or nasal disorder symptomatic enough to cause significant nasal obstruction as judged by the investigator 3. Have a clinical diagnosis of asthma 4. Have perennial allergic or non-allergic rhinitis except for cat and dog sensitivity under the condition that these subjects will not be exposed to cat and dogs during the study period. 5. Any upper respiratory tract infection (bacterial, viral or fungal infections of the airways) 2 weeks prior to Visit 1 being symptomatic enough to affect study conduct or the well-being of the subject as judged by the investigator 6. Topical glucocorticosteroid treatment within 1 month prior to Visit 1 7. Systemic glucocorticosteroid therapy for any reason during 6 weeks prior to Visit 1 8. Antihistamine treatment within 1 week prior to Visit 1 9. Subjects on immunotherapy for seasonal allergies 10. BMI < 18 kg/m3 or body weight below 65 kg 11. A marked baseline prolongation of QT/QTc (eg repeated demonstration of a QTc interval >450 ms for females and >430 ms for males 12. A history of additional risk factors for Torsade de pointes (eg heart failure, hypokalemia, family history of Long QT syndrome) 13. The use of concomitant medications that prolong the QT/QTc interval. 14. Involvement in the planning and conduct of the study (applies to both AstraZeneca staff or staff at the study site) 15. Participation in another clinical study within 1 month prior to Visit 1 16. Planned hospitalisation during the course of the study 17. Previous randomization in the present study 18. Past (within 1 year) or present alcohol or drug abuse 19. Suspected poor capability, as judged by the investigator, to follow instructions of the study

E.5 End points |
E.5.1 | Primary end point(s) |
Total Nasal Symptom Score (TNSS) morning and evening. TNSS is defined as the sum of the symptoms runny nose, blocked nose and the maximum of the scores nasal itching and sneezing. Each individual symptom is scored 0-3, so TNSS will be scored from 0-9. |
