A Randomized, Double-blind, Active Control, Parallel Group, Titration, Multicenter Study to Evaluate the Efficacy and Safety of Fimasartan

The purpose of this study is to evaluate the Efficacy and Safety of Fimasartan in patients with hypertensive diabetic chronic kidney disease.

The randomized subjects will take the investigational product (Fimasartan or Losartan) corresponding to each treatment group for 24 weeks. After that, all subjects will take Fimasartan for additional 120 weeks in an open-label, 2-parallel group study conducted with 2 groups in accordance with the blood pressure control criteria.

2. Blood pressure: Mean blood pressure is as below at screening.

   • For treatment-naïve patients: 140 mmHg ≤ SBP < 180 mmHg and DBP < 110 mmHg
   • For patients who are taking ACEI or ARB: 130 mmHg ≤ SBP < 180 mmHg and DBP < 110 mmHg

3. eGFR: ≥ 30 ml/min/1.73 m2 within the past 6 months

4. Albuminuria (ACR) excretion volume: Meets one or more of the following conditions
