简要总结
Humalog and Humulin-R (recombinant human insulin) are Food and Drug Administration (FDA) approved medications for the treatment of diabetes mellitus. Recombinant human hyaluronidase PH20 (rHuPH20) is approved by the FDA for use as an aid in the absorption and dispersion of other injectable drugs. In this study, rHuPH20 will be co-administered with both Humalog and Humulin-R in order to determine if it improves the absorption of these insulins to more closely mimic the body's natural increase in insulin in response to a meal.
详细描述
Participants received all 4 interventions in the same order.
Dose-finding visits were conducted to identify the appropriate dose of Humalog and Humulin-R. For each Humalog dose-finding visit, a total of 24 U of rHuPH20 was injected SC per unit of Humalog, corresponding to a mass concentration of 18.2 micrograms per milliliter (μg/mL) rHuPH20 (at final concentration of 91 U/mL of Humalog). For each Humulin-R dose-finding visit, a total of 24 U of rHuPH20 was injected SC per unit of Humulin-R, corresponding to a mass concentration of 20.0 μg/mL rHuPH20 (at final concentration of 100 U/mL of Humulin-R).
