简要总结
This is a 24-week, prospective, multicenter, open-label, single-arm study to assess the effect of bisoprolol on glycemic level in Type 2 diabetes mellitus (T2DM) controlled subjects with hypertension. The hypothesis of study is that there is no change in glycemic level and lipid metabolism as determined by glycosylated hemoglobin (HbA1c) using bisoprolol in T2DM subjects with suboptimal blood pressure (BP) control.
详细描述
Diabetes mellitus and hypertension are two of the most common chronic conditions, and each predisposes to accelerated atherosclerosis, cardiovascular disease, and death. There has been a concern that beta-blocker might have adverse effects in subjects with diabetes on glucose metabolism, but some data shows that highly beta-1 selective agents such as bisoprolol are essentially free of metabolic disturbances involving blood sugar, insulin sensitivity and lipids.
This is a prospective, multicenter, single-arm, open-label study to assess the glycemic effect of bisoprolol in T2DM subjects with suboptimal BP control.
After pre-screening period, each enrolled subject with T2DM and suboptimal BP control will undergo laboratory test for efficacy and safety measurement. After that, subject will continue his/her usual dosage of antihypertensive medication and bisoprolol will be added.
Subjects will be instructed to continue their diet and level of physical activity and to attempt to maintain current body weight until completion of the study.
Bisoprolol will be titrated upward until a dosage that lowers BP to less than 130/80 millimeter of mercury (mmHg) during the first 2 months of treatment. The maximum dosage of bisoprolol will be 10 mg once daily. Following 6 month of added bisoprolol therapy, all efficacy and safety measurements will be repeated.

结局指标
主要结局
Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Month 6
时间窗: Baseline, Month 6
HbA1c represents the percentage of glycosylated hemoglobin. The change in HbA1c at Month 6 was calculated as HbA1c at Month 6 minus HbA1c at baseline.
次要结局
- Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Month 3(Baseline, Month 3)
- Change From Baseline in Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) at Months 3 and 6(Baseline, Months 3 and 6)
- Change From Baseline in Total Cholesterol, Low Density Lipoprotein (LDL) Cholesterol, High Density Lipoprotein (HDL) Cholesterol and Triglyceride Level at Month 6(Baseline, Month 6)
- Change From Baseline in Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Mean Blood Pressure (BP) at Month 6(Baseline, Month 6)
- Change From Baseline in Insulin Level at Months 3 and 6(Baseline, Months 3 and 6)
- Change From Baseline in C-Peptide Level at Months 3 and 6(Baseline, Months 3 and 6)
- Change From Baseline in Albumin/Creatinine Ratio at Month 6(Baseline, Month 6)
- Change From Baseline in Microalbumin Level at Month 6(Baseline, Month 6)
- Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)(Baseline up to Month 6)
