• Normal clinical laboratory profiles, defined as complete blood count, serum chemistry, and urinalysis values within the normal range

• Willingness to abstain from concomitant use of ocular or systemic medication (excluding oral contraceptives, ibuprofen, paracetamol, calcium preparations and vitamins) from 2 weeks prior to the start of study dosing until study completion

• Willingness to comply with study-related procedures

• If menopause occurred 2 years ago at the minimum, no contraception is required for a female participant, nor pregnancy test

• Reliable contraception for a male subject is concordant with above listed methods for females, as applicable

Exclusion Criteria:

• History of ocular surgery, trauma, or chronic ocular disease

• Current use of contact lenses or discontinuation of contact lens use within 2 weeks of the first dosing day

• Any ocular abnormalities or ocular symptoms (defined as a non-zero score on assessment scales)

• Use of systemic or inhaled nasal or pulmonary corticosteroids within the past month prior to the first dosing day

• Use of systemic antihistamines within one week prior to the first dosing day

• History or evidence of ocular infection, inflammation, blepharitis, or conjunctivitis within 2 months prior to the first dosing day; history of herpes simplex keratitis at any time

• Current ocular allergy symptoms

• Loss, donation, or removal of 400 ml or more of blood within 2 months prior to the first dosing day

• Women who are pregnant or breastfeeding, or non-sterile or premenopausal women who refuse to use two proven methods of contraception during the study and for at least 30 days following the final dose of study drug

• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, would affect the subject's ability to follow study-related procedures, or may interfere with the interpretation of study results and, in the Investigator's opinion, would make the subject inappropriate for entry into this study.

• Doubtful availability to complete the study
