condition/disease : AMD(Age-related Macular Degeneration) Intervention/treatment : EB-203 or Placebo Phase : Phase I

Study Title : A Phase I clinical Trial to Evaluate Safety, Tolerability and Pharmacokinetics of EB-203 Eye Drops in Healthy Volunteers

Purpose : The purpose of study is to evaluate safety, tolerability and pharmacokinetics of EB-203 Drops in adult healthy volunteers

Number of Site : One site (INJE UNIVERSITY BUSAN PAIK HOSPITAL)

A total of 8 subjects will be dosed in each group(Group B, C, D) with subjects randomized 3:1 to EB-203 or placebo.(A total of 4 subjucts will be dosed in Group A) Up to 28 subjects will be enrolled in four consecutive cohorts. A safety data review as masking will be performed for 4days prior repeated treatment. Treatment of high dose will proceed following a review of safety data from low dose.

Safety and tolerability assessments and drug plasma concentrations will be evaluated throughout the study in all cohorts.

Outcome Measures :

1. Primary Outcome Measures

   : Frequency of AEs (Adverse Events) and ADR (Adverse Drug Reaction)

2. Secondary Outcome Measures : Pharmacokinetic variables evaluation for single and repeated dose administration.

Safety Assessment :

• V/S, Physical Exam, Laboratory Exam, ECG
• Ophthalmic Exam
