Primary Outcome Measures:
  • Percent change from baseline UACR to mean value of UACR measured on week 12 and week 16 (UACR: Urine Albumin Creatinine Ratio) [ Time Frame: Week 0, week 12 and week 16 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of subjects achieving more than 30% reduction of UACR level from baseline [ Time Frame: Week 0 and week 16 ] [ Designated as safety issue: No ]
  • Proportion of subjects achieving more than 50% reduction of UACR level from baseline [ Time Frame: Week 0 and week 16 ] [ Designated as safety issue: No ]
  • Proportion of subjects achieving more than 0.2 reduction of UACR level [ Time Frame: Week 0 and week 16 ] [ Designated as safety issue: No ]
  • Composite event rate achieving less than 0.2 or 50% reduction of UACR level [ Time Frame: Week 0 and week 16 ] [ Designated as safety issue: No ]
  • Changes of UACR measured between before the study and each visit [ Time Frame: Week 0, week 4, week 8, week 12 and week 16 ] [ Designated as safety issue: No ]
  • Incidence of adverse events according to subject's self-assessment, vital signs, investigator's assessment and labo-tests [ Time Frame: Through week 16 ] [ Designated as safety issue: No ]
