Effects of BKR-017 on Insulin Resistance in Type 2 Diabetes Patients

The purpose of this study is to evaluate the effect of BKR-017 on insulin resistance in type 2 diabetes (T2D) subjects during 28 days of active test product administration.

The study consists of a screening period followed by a 28-day treatment period. All subjects will receive test product.

There are a total of 4 study visits including screening. Visit 1 is the screening visit. Eligible subject must have an HbA1c between 6.5 -10.5% and with HOMA-IR ≥ 2.7 (calculated from fasting insulin and fasting glucose). Visits 2 and 4 are overnight visits during which time a Mixed Meal Tolerance (MMTT) will be performed after an overnight fast. The MMTT requires an indwelling IV catheter so that 11 blood draws can be more comfortably be obtained over a period of 4 hours. At Visit 3,subjects will be evaluated and test product will be replenished. Routine chemistry and hematology testing are done and two time periods during the study and a physical exam is performed at screening

2. Diagnosed with T2D and under the care of a healthcare professional for its management
3. HbA1c 6.5-10.5%, inclusive
4. HOMA-IR 2.7 and above
5. Has given written informed consent to participate in this study

5. History of significant heart disease, including congestive heart failure, prior MI, chronic atrial or ventricular fibrillation, coronary artery disease, cerebral vascular disease or other cardiovascular disease, that in the opinion of the investigator should exclude the subject from the study

11. Allergy or intolerance to Boost® High Protein drink
12. Pregnant, nursing, or trying to become pregnant
13. Presence of pitting edema on physical exam
14. High fiber diet
