- •2.History of rhinitis and perceived ET dysfunction as defined by self-reported difficulty in equalising ears during plane flights, particularly descent and a history of allergic rhinitis (hay fever), but otherwise healthy as assessed by medical history and physical examination.
- •3.Body mass index between 18 and 30 kg/m2 (inclusive).
- •4. Healthy as assessed by medical history and physical examination.
- •5.A female participant is eligible to participate if she is of:
- •a. Non-childbearing potential defined as (1) having a documented tubal ligation at least 6 weeks prior to dosing; (2) having had a surgical bilateral oophrectomy (with or without hysterectomy); (3) at least 12 months of spontaneous amenorrhoea with follicle stimulating hormone (FSH) > 40 mIU/mL.

- •b. Type As: shows same ear canal volume and middle ear pressure as Type A but the compliance (or peak) is equal to or less than 0.3 mL
- •c. Type Ad: shows same ear canal volume and middle ear pressure as Type A but the compliance (or peak) is equal to or greater than 1.6 mL
