Phase II Pharmacokinetics Study of Humalog and Humulin-R With and Without rHuPH20 in Type 1 Diabetes Mellitus

Phase 2

Completed

Conditions: Type 1 Diabetes Mellitus

Interventions: Drug: Humalog
Drug: Humulin-R
Drug: Recombinant human hyaluronidase PH20 (rHuPH20)
Other: Liquid meal

Registration Number: NCT00774800

Lead Sponsor: Halozyme Therapeutics

Brief Summary: 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.

Detailed Description: 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).

Primary Outcome Measures

Name	Time	Method
Area Under the Insulin Concentration-time Curve for the First Hour (AUC0-60)	Predose up to 60 minutes postdose	AUC was derived as the area under the serum insulin concentration profile from 0 to time "t." Samples were taken 30, 20, and 10 minutes (mins) prior to treatment; every 3 mins from mins 0 through 15; and at 20, 30, 45, and 60 mins postdose.

Secondary Outcome Measures

Name	Time	Method
Maximum Serum Insulin Concentration (Cmax)	Predose up to 480 minutes postdose	Cmax was determined as the maximum of all valid serum insulin concentration measurements for each measurement series. Samples were taken 30, 20, and 10 minutes (mins) prior to treatment; every 3 mins from mins 0 through 15; at 20, 30, and 45 mins; every 30 mins from mins 60 through 240; and every 60 minutes from mins 300 through 480 postdose.
Time to Maximum Serum Insulin Concentration (Tmax)	Predose up to 480 minutes postdose	Tmax was determined as the timepoint where the maximum of all valid concentration measurements for each measurement series was observed. Samples were taken 30, 20, and 10 minutes (mins) prior to treatment; every 3 mins from mins 0 through 15; at 20, 30, and 45 mins; every 30 mins from mins 60 through 240; and every 60 minutes from mins 300 through 480 postdose.
Area Under the Blood Glucose Time-Concentration Curve Blood Glucose (AUC[BG])	Predose up to 4 hours after injection of study drug	AUC(BG) values are reported for participants whose blood glucose (BG) was elevated higher than 140 milligrams per deciliter (mg/dL) within 4 hours of consuming a liquid meal. Blood samples were collected at 30, 20, 10, and within 5 minutes before; at 3, 6, 9, 12, 15, 20, 25 minutes; and every 10 minutes from minute 30 to 240 postdose.
