Clinical Study to Investigate the Systemic Exposure, Safety, and Local Tolerability of SJP002 Ophthalmic Solution in Healthy Male Volunteers

This is a phase1, single center, double-blind, placebo control, randomized study and consisted of single dosing(period 1) and multiple dosing(period 2).

In this clinical trial, safety and local tolerability are evaluated for 7 days after single dosing of the investigational product. If multiple dosing is judged to be acceptable as a result of single dosing evaluation (safety and local tolerability evaluation including ophthalmic examination), multiple dosing starts from Day 8(7 days after the single dosing) for 14 days. Safety and local tolerability, including ophthalmic symptom assessment, should be evaluated during the multiple dosing period.
