Brief Summary

Type 2 diabetes mellitus is a chronic metabolic disease that seriously affects patients worldwide, and it is always among the top 10 causes of death in Taiwan. To date, still many patients who take more than three kinds of oral hypoglycemic agents could not effectively control their glycohemoglobin levels in clinics. Hypoglycemia as well as weight gain are common side effect with insulin therapy, and many patients in Taiwan are not willing to receive insulin injection. It is common for diabetic patients treated with Chinese herbal medicine in China currently, and some therapeutic effects have been published in international journals. In this study, we will evaluate whether Chinese herbal medicine, YH1, enhances the glycemic control and is safe as add-on medication in poorly controlled type 2 diabetes patients. A total of 46 poorly controlled type 2 diabetes patients with glycohemoglobin ≥ 7% from Endocrinology and Metabolism clinics or Internal Chinese Medicine clinics will be enrolled in this randomized double-blind placebo-controlled trial. Subjects will be randomly assigned to receive either YH1 (6 g) or the placebo three times per day for 12 consecutive weeks. All subjects in both groups will also continuously receive their oral hypoglycemic agents without any dose or medicine change. During this 12-week period, the glycohemoglobin, fasting plasma glucose, 2h postprandial glucose, waist circumference, body weight, and body mass index will be assessed. In addition, insulin resistance, β -cell function, lipid profile, liver and renal function will also be evaluated. Independent statisticians will perform the data analysis at the end of the trial.

Outcome Measures

Primary Outcomes (1)

  • The Percentage Change in HbA1c Level From Baseline to 12 Weeks

    The primary efficacy endpoint was the percentage change in HbA1c levels from baseline to 12 weeks. The HbA1c level was measured by HPLC in the Department of Laboratory Medicine at Chang Gung Memorial Hospital.

    12 weeks

Secondary Outcomes (1)

  • The Percentage Change in 2hPG From Baseline to Week 12

Study Arms (2)

YH1 group

EXPERIMENTAL

YH1 with one batch number was manufactured by Sun Ten Pharmaceutical Co., Ltd., a renowned manufacturer of concentrated herbal extract granules conforming to the standards of good manufacturing practices (GMP) in New Taipei City, Taiwan. YH1 contains Rhizoma Coptidis (50 %) and Shen-Ling-Bai-Zhu-San (SLBZS) (50 %). SLBZS consists of Radix Ginseng, Poria, Rhizoma Atractylodis macrocephalae, Semen Lablab album, Rhizoma Dioscoreae, Embryo Nelumbinis, Radix Platycodonis, Semen Coicis, Fructus Amomi, Fructus Jujubae, and Radix Glycyrrhizae at a 3:3:3:2.3:3:1.5:1.5:1.5:1.5:1.5:3 ratio. Subjects in the YH1 group orally ingested two packages of granules (3 g/package) three times daily with warm water after a meal for 12 consecutive weeks.

Drug: YH1 group

placebo group

PLACEBO COMPARATOR

The placebo was also prepared as granules by Sun Ten Pharmaceutical Co., Ltd., and the packaging of the placebo was identical to that of YH1. Subjects in the placebo group orally ingested two packages of granules (3 g/package) three times daily with warm water after a meal for 12 consecutive weeks.

Drug: placebo group

Interventions

Participants were randomly assigned 1:1 to receive either YH1 or placebo for 12 consecutive weeks.
