Overview
Brief Summary
This clinical study is designed as a multi-center, randomized, double-blind, placebo-controlled, parallel design, prospective, phase II clinical trial.
An eligible subject who meets inclusion and exclusion criteria is randomly assigned to three groups: study group 1 (GV1001 0.56 mg), study group 2 (GV1001 1.12 mg) or placebo group. A randomized subject is administered either GV1001 or placebo in a total of 14 times and will be evaluated for the efficacy and safety at week of 24.
Detailed Description
GV1001 0.56 mg, 1.12 mg or placebo is subcutaneously administered once weekly schedule for 4 weeks (4 times) followed by every two weeks until week 24 (10 times). A total number of administration is 14 times. 1. Control group (placebo): 30 subjects 2. Study group 1 (GV1001 0.56 mg): 30 subjects 3. Study group 2 (GV1001 1.12 mg): 30 subjects.
