Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Low (2 mg/day)Subjects in the 2 mg/day group will be administered 2 mg once daily for 6 weeks (42 days).

Mid (6 - 12 mg/day)Subjects in the 6-12 mg/day group will be administered 2 mg once daily for 2 days, followed by a maintenance dose of 6 mg for 40 days. From Day 15 onwards, the dose may be increased to 12 mg in accordance with the criteria below.

High (24 - 30 mg/day)Subjects in the 24-30 mg/day group will be administered 2, 6, 12, 18 mg sequentially, each dose once daily for 2 days respectively, followed by a maintenance dose of 24 mg for 34 days.
