- 1. SmartCells, Inc. An Introduction to SmartInsulinTM Todd C. Zion, Ph.D. Co-founder, President & CEO April 6th, 2009 e-mail: todd.zion@smartinsulin.com Phone: 978.927.4246 Web: www.smartinsulin.com 1 SmartCells, Inc.
- 2. Imagine a “Smart” Insulin Calculate Insulin Dose SmartInsulinTM Food Food Measure Blood Glucose Blood Glucose • Once-a-day injection • No hypoglycemia • Near-perfect glucose control • Significantly fewer finger-sticks • Minimal dietary restrictions 2 SmartCells, Inc.
- 3. SmartCells, Inc. and the SmartInsulinTM Mission • Founded in August 2003 – Exclusive licensee from M.I.T. – Based on founder’s 5+ years of Ph.D. research • World-class collaborators to complement 12 full-time employees – Management includes founder, M.I.T. Ph.D.’s, and biotech executives – Collaborators from M.G.H., Joslin, former Lilly/Novo experts • $4.2M+ in private investment; $6.3M+ in public grant funds Corporate Headquarters in Beverly, MA (25 miles north of Boston) For more information, please visit www.smartinsulin.com 3 SmartCells, Inc.
- 4. Insulin and Type 1 Diabetes • Insulin saves lives, BUT with… – Life-threatening bouts of hypoglycemia – Poor glucose control and long-term complications – Frequent finger sticks and counting carbs – Constant vigilance • Insulin lowers blood glucose levels no matter what – Too much: Hypoglycemia – Too little: Hyperglycemia and ketoacidosis • Effective control requires glucose-responsive delivery 4 SmartCells, Inc.

Pharmacol. 2 (2002) 708-716. tibility Better algorithms and device integration • SmartCells makes the insulin molecule glucose-responsive • Eliminates the need for cells, pumps, sensors and algorithms 6 SmartCells, Inc.
- 7. Glucose-responsive SmartInsulin technology Insulin Key: Insulin Glycosylated insulin-polymer conjugate (IPC) Insulin Glucose Multivalent glucose-binding molecule (GBM) Conceptual particle surface boundary 1. IPC and GBM combine to form insoluble network 2. Free glucose molecules displace the IPC from the GBM 3. The matrix erodes from the surface inward 4. The released IPC lowers glucose levels in the body 5. The matrix stops eroding until the next glucose challenge 7 SmartCells, Inc.
