Comparative pharmacokinetics and insulin action for three rapid-acting insulin analogs injected subcutaneously with and without hyaluronidase

Abstract

OBJECTIVE-To compare the pharmacokinetics and glucodynamics of three rapid-acting insulin analogs (aspart, glulisine, and lispro) injected subcutaneously with or without recombinant human hyaluronidase (rHuPH20). RESEARCH DESIGN AND METHODS-This double-blind six-way crossover euglycemic glucose clamp study was conducted in 14 healthy volunteers. Each analog was injected subcu-taneously (0.15 units/kg) with or without rHuPH20. RESULTS-The commercial formulations had comparable insulin time-exposure and time-action profiles as follows: 50% exposure at 123-131 min and 50% total glucose infused at 183- 186 min. With rHuPH20, the analogs had faster yet still comparable profiles: 50% exposure at 71-79 min and 50% glucose infused at 127-140 min. The accelerated absorption with rHuPH20 led to twice the exposure in the first hour and half the exposure beyond 2 h, which resulted in 13-to 25-min faster onset and 40- to 49-min shorter mean duration of insulin action. CONCLUSIONS- Coinjection of rHuPH20 with rapid-acting analogs accelerated insulin exposure, producing an ultra-rapid time-action profile with a faster onset and shorter duration of insulin action.© 2013 by the American Diabetes Association.
