Assessment

Primary outcomes

The development of type 2 diabetes from prediabetes between the two groups after 3-year treatment.

Key secondary outcomes

1. The improvement ratio from prediabetes to normoglycemia.
2. The incidence of type 2 diabetes after adjusting for treatment group (eldecalcitol or placebo) and confounding factors at baseline: age, sex (male/female), presence or absence of hypertension (systolic 140 or more mmHg and/or diastolic 90 or more mmHg), body mass index, family history of diabetes (yes / no), HbA1c, fasting plasma glucose, 2-hour plasma glucose, 25-hydroxy vitamin D, and 1,25-dihydroxy vitamin D.
3. The incidence of type 2 diabetes in each subgroup at baseline variables: age (more or less 65 years), sex (male/female), obesity (BMI more or less 25 kg/m2), presence or absence of hypertension (systolic more 140 mmHg and/or diastolic more 90 mmHg), family history of diabetes (yes / no), fasting plasma glucose (more or less 110 mg/dl), 2-hour plasma glucose (more or less 170 mg/dl), 25-hydroxy vitamin D (more or less 20 ng/ml), and 1,25-dihydroxy vitamin D (more or less 20 pg/ml).
4. The incidence of adverse events between the two groups.

Interventions/Control_1

Participants take 0.75 mcg of eldecalcitol capsule once daily for at least 3 years. However, the study will be ended when a patient is diagnosed with type 2 diabetes. First interim analysis will be performed after one year of enrollment of all 903 participants. A second interim analysis will be performed when 60% (97 patients) of the 161 patients, who are expected to develop diabetes during the 3-year period, develop type 2 diabetes.

Interventions/Control_2

Participants take placebo capsule once daily for at least 3 years. However, the study will be ended when a patient is diagnosed with type 2 diabetes. First interim analysis will be performed after one year of enrollment of all 903 participants. A second interim analysis will be performed when 60% (97 patients) of the 161 patients, who are expected to develop diabetes during the 3-year period, develop type 2 diabetes.
