EXPERIMENTAL

In GV1001-PSP-CL2-011 study, subjects who were in the trial group (Study Group 1(GV1001 0.56 mg/day), Study Group 2(GV1001 1.12 mg/day) is alternately administered High-dose test drug(GV1001 1.12 mg/day) and placebo once a week from Ex-Visit 1(Visit 16, Week 26) to Ex-Visit 5(Visit 20, Week 30) and High-dose test drugs(GV1001 1.12 mg/day) are administered from Ex-Visit 6 (Visit 21, Week 32) to Ex-Visit 26(Visit 41, Week 72) every two weeks. In the GV1001-PSP-CL2-011 study, subjects who were in the placebo group are administered placebo at Ex-Visit 1 (Visit16, Week26), the first visit of the extension study, and Ex-Visit 2 (Visit17, Week27) to Ex-Visit 5 (Visit 20, Week 30), High-dose test drugs(GV1001 1.12 mg/day) are administered once a week and High-dose test drugs (GV1001 1.12 mg/day) are administered from Ex-Visit 6 (Visit 21, Week 32) to Ex-Visit 26(Visit 41, Week 72) every two weeks.
