Our endocrinology development activity focuses on insulin, a mainstay of treatment for people with diabetes. This investigational program combines our rHuPH20 hyaluronidase enzyme with mealtime analog insulin, a frequently prescribed, commercially successful pharmaceutical already approved and on the market. We are evaluating our technology for use with insulin pumps and for mealtime insulin administration.
Ultrafast Insulin – Mealtime
We are evaluating whether the combination of currently available insulin products with our rHuPH20 enzyme results in more rapidly absorbed and faster-acting insulin with a shorter duration of effect and greater consistency from dose to dose. We believe that a faster, more reproducible action will address important unmet medical needs, such as better and more consistent glycemic control with less hypoglycemia and hyperglycemia, and less weight gain. These potential benefits would be significant but must first be demonstrated and proven in clinical development.
Many patients with diabetes require intensive insulin therapy to control their blood glucose, to essentially mimic the blood glucose control achieved in people without diabetes. Most patients inject a long-acting insulin once daily to provide their basal insulin requirements for overnight and between meals, and inject a rapid acting insulin before each meal to control mealtime or mealtime blood glucose rises. Alternatively, some patients deliver a rapid acting insulin by pump to provide both their basal and mealtime insulin needs.
Halozyme’s “Ultrafast Insulin” development programs are investigating the use of our rHuPH20 hyaluronidase enzyme in novel formulations with faster-acting insulin analogs for the treatment of diabetes and also for use with insulin pumps. The primary goal of our Ultrafast Insulin programs is to develop best-in-class mealtime insulin therapies. Because research indicates that more responsive insulin leads to better glucose control, our clinical studies for the combination of our rHuPH20 enzyme with fast-acting insulin analogs evaluated the rate of absorption, onset and duration of action. We believe that an ultrafast insulin profile may provide best-in-class mealtime insulin coverage for patients using intensive insulin therapy to manage their diabetes.
