Brief summary
This is a single-center, double-masked, randomized, vehicle-controlled study conducted in China in adult healthy subjects
Detailed description
This is a Phase I, randomized, double-masked, vehicle-controlled study to evaluate the safety, tolerability and pharmacokinetics of 0.25%, 0.5% and 1.0% VVN461 Ophthalmic Solution in healthy male and female volunteers in China. The study consisted of a screening period (D-7 to D-1), a baseline visit (D-1), a single-dose period (D1), QID multi-dose period (D2 to D5), six times daily multi-dose period (D6 to D9), discharge (D10), and a follow-up/EOS (D16,+1D). During the single-dose period, subjects will receive one drop of VVN461 eye drops (0.25%, 0.5%, or 1.0%) or vehicle in the study eye. For the multi-dose period, subjects will receive one drop of VVN461 eye drop (0.25%, 0.5% or 1.0%) or vehicle in the study eye four or six times a day. PK blood samples will be collected before and after dosing at D1, D5 and D9.

Exclusion criteria
* Known hypersensitivity or contraindications to the study drug or its components * Anatomical anomalies in either eye * History of eye surgery (other than blepharoplasty) or laser treatment of the eye (including keratoconus) in either eye * Blepharoplasty on either eye within 3 months prior to screening * History of subchoroidal or vitreous injection in either eye * Infectious eye disease, immunological eye disease, inflammatory eye disease or ocular trauma in either eye within three months prior to screening; * Use of topical ophthalmic medications (including artificial tears, proprietary drops and OTC ophthalmic medications) in either eye within 1 month prior to screening * Using contact lens in either eye within 14 days prior to screening or unable to discontinue the use of contact lens during the study * A history of eye disease such as glaucoma, corneal opacity, corneal degeneration, corneal dystrophy, uveitis, fundopathy, or other ophthalmic disease in either eye, which is assessed by the investigator to be contraindicated for participation in the trial.
