Eligibility Criteria
Ages Eligible for Study
18 years to 65 years (Adult, Older Adult)
Accepts Healthy Volunteers
Yes
Genders Eligible for Study
Male
Description
Inclusion Criteria:
- Healthy males
- Aged 18 to 65 years
- A body weight of >50 kg and body mass index .18.0 to <32.0 kg/m2
- Must be willing and able to communicate and participate in the whole study
- Must provide written informed consent
- Must agree to use an adequate method of contraception
Exclusion Criteria:
- Subjects who have received any IMP in a clinical research study within the previous 3 months
- Subjects who are study site employees, or immediate family members of a study site or sponsor employee
- Subjects who have previously been enrolled in this study
- History of any drug or alcohol abuse in the past 2 years
- Regular alcohol consumption >21 units per week (1 unit = ½ pint beer, 25 mL of 40% spirit or a 125 mL glass of wine)
- Current smokers and those who have smoked within the last 12 months. A confirmed positive urine cotinine test at screening and admission
- Current smokers of e-cigarettes and nicotine replacement products and those who have smoked these products within the last 12 months
- Subject who have significant history of any tobacco use at any time (total ≥10 pack years history)
- Subjects who do not have suitable veins for multiple venepunctures as assessed by the investigator at screening
- Clinically significant abnormal biochemistry, haematology, coagulation or urinalysis as judged by the investigator (laboratory parameters are listed in Appendix 1)
- Positive drugs of abuse test result (drugs of abuse tests are listed in Appendix 1)
- Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results
- History of clinically significant cardiovascular, renal, hepatic, chronic respiratory or gastrointestinal disease, or psychiatric disorder, as judged by the investigator
- Any chronic medical condition that could significantly reduce the ability of the subject to participate in the study or pose a safety concern eg unstable angina, uncontrolled diabetes mellitus, anaemia
- Any concurrent serious illness (eg diagnosis of severe depression, pulmonary hypertension, history of malignancy) that may interfere with a subject completing the study. Basal cell carcinoma within 5 years of initial diagnosis or with evidence of recurrence is also an exclusion
- Any finding in the medical history review, physical examination (including nasal exam with nasal speculae), screening investigations, that in the opinion of the investigator would compromise the subject's ability to safely complete the study
- Has experienced upper or lower respiratory infection (viral, fungal or bacterial) that resolved less than 4 weeks before Day 1
- Has required antibiotic treatment for a lower respiratory tract infection in the 3 months prior to the study
- Subjects with a significant nasal condition eg Wegener's granulomatosis, that could interfere with study assessments
- Any significant abnormality altering the anatomy of the nose or nasopharynx on examination
- Any nasal or sinus surgery within 6 months of Day 1
- Any clinically significant history of epistaxis (nosebleeds) within the last 12 months and/or history of being hospitalised due to epistaxis on any previous occasion
- History or evidence of autoimmune disease or known immunodeficiency of any cause - with the exception of atopic eczema/atopic dermatitis. Subjects with clinically mild atopic eczema/atopic dermatitis may be included at the Investigator's discretion (eg if there is no regular use of topical steroids, no eczema in cubital fossa)
- Subjects with known history of Immunosuppression or known chronic viral infection
- Has active seasonal or perennial nasal/pharyngeal allergies at screening visit; or anticipates to have such symptoms during the study duration; or has had symptoms in the 4 weeks prior to Day 1
- Presence or history of clinically significant allergy requiring treatment (including food or drug allergy), as judged by the investigator
- Known allergy or adverse reaction history to formulation components
- Donation or loss of greater than 400 mL of blood within the previous 3 months
- Subjects who are taking, or have taken, any prescribed or over-the-counter drug (other than 4 g per day paracetamol) or herbal remedies in the 14 days before IMP administration (see Section 11.4). Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the PI and sponsor's medical monitor
- Failure to satisfy the investigator of fitness to participate for any other reason
