Age verification will be performed by checking valid forms of government-issued identification (e.g., passport, driving licence or validate UK card) during Screening.
2. Female subject of childbearing potential willing to use 2 effective methods of contraception, i.e., established method of contraception + condom, if applicable (unless of non-childbearing potential or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) from the first dose until 1 month after the last dose of IP.
3. Female subject of non-childbearing potential. For the purposes of this study, this is defined as the subject being amenorrhoeic for at least 12 consecutive months or at least 4 months post-surgical sterilisation (including bilateral fallopian tube ligation or bilateral oophorectomy with or without hysterectomy).
4. Female subject with a negative pregnancy test at Screening Visit and before the first dose administration of the IP on Day 1.
5. Female subject of post-menopausal status confirmed by demonstrating at Screening Visit that the serum level of the follicle-stimulating hormone (FSH) falls within the respective pathology reference range. In the event a subject's menopausal status has been clearly established (for example, the subject indicates she has been amenorrhoeic for 10 years, confirmed by medical history, etc), but serum FSH levels are not consistent with a postmenopausal status, determination of the subject’s eligibility to be included in the study will be at the Investigator’s discretion following consultation with the Sponsor.
6. Male subject willing to use 2 effective methods of contraception, i.e., established method of contraception + condom, if applicable (unless anatomically sterile or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) from Day 1 visit until completion of the Follow Up Phone Call.

This should include conventional cigarette smokers, e-cigarette users, roll-your-own cigarette smokers or dual users (of either conventional cigarette and/or roll-your-own cigarette smokers and e-cigarette users).
9. No clinically significant abnormal laboratory test results (in the opinion of the investigator) for serum biochemistry and haematology within 28 days before receiving the first dose administration of the IP.
10. Subject with a negative urinary DOA screen (including alcohol) test results, determined within 28 days before the first dose administration of the IP unless there is a documented medical explanation for the positive result other than drugs of abuse (e.g., the subject has been presc

4. Subject who has, or who has had a relevant history of any clinically significant: neurological, gastrointestinal, renal, hepatic, cardiovascular, psychiatric, respiratory, metabolic, endocrine, or haematological conditions and/or other significant medical conditions including, without limitation, those pertaining to COVID-19 that, in the opinion of the Investigator or their appropriately qualified designee, would jeopardise the safety of the subject, safety of anyone involved in the study or impact on the validity of the study results
5. Subject who has used prescription or over-the-counter bronchodilator medication (e.g. inhaled or oral ß-adrenergic agonists) to treat a chronic condition within the 12 months prior to Screening visit
