To evaluate the safety, local tolerability and pharmacokinetic characteristics after administration of eye-drop HL036 in healthy Korean male volunteers

A total of 10 subjects will be dosed in each group with subjects randomized 8:2 to HL036 or placebo. Three of 10 subjects will be randomized to the sentinel dosing in each group. A safety data review as masking will be performed for 3days prior to the other subjects treatment. Treatment of high dose will proceed following a review of safety data from low dose.

Inclusion Criteria:

• Subjects who listened to the description about characteristics of this clinical trial and signed the IRB approved consent form before the whole screening tests
• Healthy Korean males volunteers who are 20 to 50 years old at screening procedure

Exclusion Criteria:

• Subjects who have participated in another clinical trial or bioequivalence research with an IP within 3 months prior to the first day of dosing.

• Subjects who donated whole blood within 2 months or component blood within 1 month or who are donated within 1 month prior to the first day of dosing.
