Study Description

Brief Summary:

This is a double-blind, randomized, placebo-controlled, parallel-group comparison study to evaluate the efficacy and safety of Cyclo-Z for the treatment of subjects with obese type 2 diabetes.

The study will consist of 3 phases:

• Screening phase (2 weeks)
• Treatment phase (12 weeks)
• Follow-up phase (2 weeks)

Following a 2-week screening period, subjects who meet all inclusion and exclusion criteria will be randomly assigned into one of the following treatment arms:

• Dose A: Cyclo-Z containing 23 mg zinc plus 3 mg CHP - 16 subjects
• Dose B: Cyclo-Z containing 23 mg zinc plus 9 mg CHP - 16 subjects
• Dose C: Cyclo-Z containing 23 mg zinc plus 15 mg CHP - 16 subjects
• Dose D: Placebo - 16 subjects

The assigned dose will be orally administered to subjects once a day before bedtime for 12 consecutive weeks. After the randomization at Week 0 (Visit 2), subjects will visit their respective trial sites at Weeks 2, 4, 6, 8, 10, 12, and 14 (Visits 3, 4, 5, 6, 7, 8, and 9).

Arms and Interventions

Arm	Intervention/treatment
Experimental: Dose A; Cyclo-Z containing 23 mg zinc plus 3 mg CHP	Drug: Cyclo-Z
Experimental: Dose B; Cyclo-Z containing 23 mg zinc plus 9 mg CHP	Drug: Cyclo-Z
Experimental: Dose C; Cyclo-Z containing 23 mg zinc plus 15 mg CHP	Drug: Cyclo-Z

Outcome Measures

Primary Outcome Measures :

1. Change of HbA1c Level From Baseline [ Time Frame: 12 weeks ]
   Change in HbA1c from Day 1 to Week 12
2. Change of Body Weight From Baseline [ Time Frame: 12 weeks ]
   Change in body weight from Day 1 to Week 12

Secondary Outcome Measures :

1. Change of Fasting Plasma Glucose Level From Baseline [ Time Frame: 12 weeks ]
   Change in fasting plasma glucose from Day 1 to Week 12
2. Proportion of Subjects Achieving HbA1c Goal of <7.0% [ Time Frame: 12 weeks ]
   Percent of subjects who achieved HbA1c of <7% at Week 12
3. Proportion of Subjects Achieving HbA1c Goal of <6.5% [ Time Frame: 12 weeks ]
   Percent of subjects who achieved HbA1c of <6% at Week 12
4. Change in Waist Circumference From Baseline [ Time Frame: 12 weeks ]
   Change in waist circumference from Day 1 to Week 12
5. Change of Postprandial (2 Hours After Dinner) Blood Glucose Level From Baseline [ Time Frame: 12 weeks ]
   Change in postprandial (2 hours after dinner) blood glucose levels from Day 1 to Week 12
6. Change of Oral Glucose Tolerance Test From Baseline [ Time Frame: 12 weeks ]
   Change in oral glucose tolerance test results from Day 1 to Week 12
7. Change of Score in Audit of Diabetes-Dependent Quality of Life Questionnaire From Baseline [ Time Frame: 12 weeks ]
   Individual 19 domains were calculated as a weighted score (WS) for each domain. Average weighted impact score = summing of WS for each domain/19 domains. Total range possible is -9 to 3, and higher number means improvement in quality of life.
