• Lead Sponsor: Shanghai Medinno Pharmaceutical Technology Co., Ltd.

Brief Summary

The main goal of this clinical trial is to evaluate the safety, tolerability and pharmacokinetics (PK) profiles\* of MDI-1228_mesylate Ophthalmic Solution in healthy adult participants.

Participants will receive either of the following treatment:

* MDI-1228_mesylate Ophthalmic Solution, or

* Placebo\*\*

Researchers will observe any changes in health (if any) in participants receiving the study treatment to evaluate the safety and tolerability\*\*\* of the study drug. Researchers will also collect several blood samples from participants to study PK profiles of the drug.

Note:

\*PK profiles: how the drug interacts with the body. \*\*placebo: a harmless substance that contains no active agents. \*\*\*tolerability: how well you can tolerate the drug.
