    Time frame: Week 0, week 12 and week 16

Secondary outcomes

  1. Proportion of subjects achieving more than 30% reduction of UACR level from baseline

    Time frame: Week 0 and week 16

  2. Proportion of subjects achieving more than 50% reduction of UACR level from baseline

    Time frame: Week 0 and week 16

  3. Proportion of subjects achieving more than 0.2 reduction of UACR level

    Time frame: Week 0 and week 16

  4. Composite event rate achieving less than 0.2 or 50% reduction of UACR level

    Time frame: Week 0 and week 16

  5. Changes of UACR measured between before the study and each visit

    Time frame: Week 0, week 4, week 8, week 12 and week 16

  6. Incidence of adverse events according to subject's self-assessment, vital signs, investigator's assessment and labo-tests

    Time frame: Through week 16
