Overview
Brief Summary
This study aims to observe changes in various indicators of renal function, such as proteinuria at different time points: short-term (Week 8), 6 months (Week 26), and a year (Week 52), in patients with DKD and hypertension, who are given antihypertensives containing fimasartan, in an actual clinical environment where a variety of patient characteristics are reflected.
Detailed Description
This prospective observational study is conducted in about 5 medical institutions located in Korea, which are equal to or larger than a hospital, and patients with type 2 diabetic kidney disease (proteinuria with an ACR of 10 mg/g or higher), who are being administered or plan to be administered with antihypertensives containing fimasartan for essential hypertension, are enrolled as the subjects. Each of the subjects shall undergo follow-up for about a year (52 weeks). After explaining the purpose, method, scope of information to be collected, and procedure of this study to potential subjects, the investigator shall obtain the written consent for voluntary participation and set the day when the antihypertensive containing fimasartan is administered as the baseline. If the fimasartan-based antihypertensive treatment is already ongoing, only the patients within 6 weeks from the baseline shall be considered as the subjects. In this case, data from between the baseline and the time of the written consent shall be collected retrospectively. This study is an observational study, and the drugs which are administered during the study period and the medical procedures shall be in accordance with the clinical judgment of the investigator. It is a rule that no unnecessary intervention shall be imposed on the subjects by this study protocol. The scope of data to be collected during this study period is as follows. * Demographic information * Disease information (diabetes, hypertension, renal disease, other past medical history and intercurrent diseases) * Physical measurements (height and weight) * Clinic blood pressure measurements * Laboratory test results * Antihypertensives, hypoglycemic agents, and other concomitant drugs * Fimasartan-related adverse drug reactions and serious adverse drug reactions * Death information (if applicable)
Investigators
Eligibility Criteria
Inclusion Criteria
- •Male and female adults aged 19 or older
- •Those who were diagnosed with type 2 diabetes and have been being given stable doses of hypoglycemic agents for 8 weeks or longer
- •Those in whom albuminuria was found to meet one of the following criteria two times before the administration of the antihypertensive treatment containing fimasartan (results (baseline values) within 4 weeks before the administration of antihypertensives must be ACR or AER results)
- •An albumin/creatinine ratio (ACR) of 10 mg/g or higher or

- •A proteinuria/creatinine ratio (PCR) of 70 mg/g or higher or
- •A urine dipstick result of trace to 1+ or higher
- •Those who plan to be given antihypertensive treatment containing fimasartan for essential hypertension or are being given the treatment (in this case, those with an administration period of 6 weeks or lower can be enrolled)
- •Those with records of clinical systolic blood pressure of 140 mmHg or higher or diastolic blood pressure of 85 mmHg or higher before the antihypertensive treatment containing fimasartan or at the time of the treatment. The following additional criteria shall be applied depending on age and the presence of comorbidities.
- •Aged younger than 65: Systolic blood pressure of 130 mmHg or higher or diastolic blood pressure of 80 mmHg or higher shall be applied to those with cardiovascular disease or an ACR or AER of 30 mg/g or higher.
Exclusion Criteria

- •Patients with moderate to severe hepatic dysfunction (ALT and/or AST of over three times the upper limit of normal) or patients with biliary tract obstruction
- •Pregnant and breast-feeding women
- •Those who were administered with drugs for clinical studies within 12 weeks from the enrollment or those who plan on participating in other clinical studies while participating in this study
- •Other subjects who are considered inappropriate to participate in the study by the investigator's decision
