Below and on the next page are questions to help discover whether you may be eligible to participate in the University of Sydney trial.
By completing this online form you agree that your information will be collected and stored by SFI Research for the purposes of assessing your potential eligibility for the trial. Should you be eligible for the trial, a representative from University of Sydney will call you to ask you a few more questions about your medical history.
Are you overweight and have an elevated blood sugar level?
Are you based in Sydney?
If so, you are invited to take part in a diabetes prevention study comparing dietary supplements to aid in weight loss and blood sugar control.
Lead researchers at Charles Perkins Centre (Dr Nicholas Fuller and Clinical Associate Professor Tania Markovic) are seeking participants interested in weight loss and preventing diabetes for a double blinded, randomised controlled trial to determine the efficacy of FBCx® (a formula based on α-cyclodextrin) on cholesterol, and the efficacy of GINST15™ (a ginseng extract formula) on glycaemic control.
Over a period of 12 months, you will receive dietary supplements and weight loss advice from our dietitians, psychologists and exercise physiologists at no cost to you.
Products being investigated
- FBCx® is a polysaccharide (a complex sugar) derived from corn. It has been demonstrated to prevent the absorption of dietary fat. FBCx® is effective in reducing and/or maintaining a healthy body weight. Studies also suggest FBCx® may increase insulin sensitivity and improve cholesterol and triglyceride levels in people with high levels of triglycerides.
- GINST15™: The root of ginseng has long been used in traditional Chinese medicine, most recently for improving glycaemic control. GINST15™ has been shown to be the active ingredient in ginseng for this anti-diabetic action.
It is proposed that these products may overlap in their function and therefore are being compared in the same study for the prevention of type 2 diabetes.
Should you agree to participate in this study, you will be asked to sign the Participant Consent Form at a “screening” visit. You will then be asked to undergo the following procedures:
- Measurement of height, body weight, and waist circumference
- Recording of your medical history (including any forthcoming procedures)
- Recording of any medications you are currently taking
- Measurement of blood pressure and heart rate
- Electrocardiogram (ECG)
- Collection of a 50 mL blood sample
- Handgrip strength test
- Dexa scan (a full body composition scan)
- Urine collection (for women of child bearing potential only)
- Completion of questionnaires
