Study Description

Brief Summary:

Insulin lispro and regular human insulin are Food and Drug Administration (FDA)-approved medications for the treatment of diabetes mellitus. Recombinant human hyaluronidase (rHuPH20) is approved by the FDA as an aid to the absorption and dispersion of other injectable drugs. In this study, rHuPH20 will be co-administered with both insulin lispro and regular human insulin 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.

Condition or disease	Intervention/treatment	Phase
Diabetes Mellitus	Drug: Insulin Lispro; Drug: Regular Human Insulin; Drug: rHuPH20	Phase 1

Detailed Description:

The purpose of this study is to compare the pharmacokinetics (absorption, distribution, breakdown and elimination) of regular human insulin + recombinant human hyaluronidase (rHuPH20) versus insulin lispro alone, and to compare the pharmacokinetics of insulin lispro + rHuPH20 versus insulin lispro alone. The effects of regular human insulin + rHuPH20, insulin lispro + rHuPH20, and insulin lispro alone on the body will be evaluated by blood glucose measurements and by calculating the rate at which a glucose solution is infused to maintain blood glucose within a certain range. The safety and tolerability of insulin lispro with and without rHuPH20 and regular human insulin with rHuPH20 will be studied. The study drugs will be administered by subcutaneous (under the skin) injection.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Insulin Lispro, Regular Human Insulin, rHuPH20; All participants were randomized to 1 of 6 treatment sequences (ABC, ACB, BAC, BCA, CAB, or CBA), each of which was comprised of the same 3 interventions (A, B, and C). Intervention A: a single, subcutaneous (SC) injection of 0.15 units per kilogram (U/kg) insulin lispro with 3.75 nanograms per kilogram (ng/kg) recombinant human hyaluronidase (rHuPH20) Intervention B: a single, SC injection of 0.15 U/kg regular human insulin (RHI) with 3.75 ng/kg rHuPH20 Intervention C: a single, SC injection of 0.15 U/kg insulin lispro alone There was a washout period of 3 to 14 days between interventions. The treatment sequence (ABC, ACB, BAC, BCA, CAB, or CBA) was repeated once so that each participant received up to 6 injections.

Outcome Measures

Primary Outcome Measures :

1. Intra-participant Variability in Percent of Total Area Under the Plasma Insulin Concentration-Versus-Time Curve Attained by Time T (%AUC[0-T]) [ Time Frame: predose up to 30 minutes postdose ]
   Blood samples were taken 30, 20, 10 minutes (mins) prior to each injection; every 3 mins (from 0 to 15 mins); and every 5 mins (from 15 to 30 mins) after each injection. The percent coefficient of variation (CV%) was calculated as 100*(standard deviation/mean). The intra-participant CV% was calculated directly from the 2 replications of each treatment. The CV% for percentage of total AUC is reported from 0 to 30 minutes.

Secondary Outcome Measures :

1. Time to Early and Late 50% Maximum Serum Insulin Concentration (t[50%Max]) [ Time Frame: predose up to 480 minutes postdose ]
   Blood samples were taken 30, 20, 10 minutes (mins) prior to each injection; every 3 mins (from 0 to 15 mins); every 5 mins (from 15 to 30 mins); every 15 mins (from 30 to 90 mins); every 30 mins (from 90 to 240 mins); and every 60 mins (from 240 to 480 mins) after each injection.
2. Peak Serum Insulin Concentration (Cmax) [ Time Frame: predose up to 480 minutes postdose ]
   Cmax was determined as the maximum of all valid serum insulin concentration measurements for each measurement series. Blood samples were taken 30, 20, 10 minutes (mins) prior to each injection; every 3 mins (from 0 to 15 mins); every 5 mins (from 15 to 30 mins); every 15 mins (from 30 to 90 mins); every 30 mins (from 90 to 240 mins); and every 60 mins (from 240 to 480 mins) after each injection.
3. Time to Percentage of Total Glucose Infused [ Time Frame: predose up to 480 minutes postdose ]
   Blood samples were taken 30, 20, 10 minutes (mins) prior to each injection; every 3 mins (from 0 to 15 mins); every 5 mins (from 15 to 30 mins); every 15 mins (from 30 to 90 mins); every 30 mins (from 90 to 240 mins); and every 60 mins (from 240 to 480 mins) after each injection. Time to 25%, 50%, and 75% of total glucose infused are summarized.
4. Percentage of Total Glucose Infused [ Time Frame: predose up to 240 minutes postdose ]
   Blood samples were taken 30, 20, 10 minutes (mins) prior to each injection; every 3 mins (from 0 to 15 mins); every 5 mins (from 15 to 30 mins); every 15 mins (from 30 to 90 mins); and every 30 mins (from 90 to 240 mins) after each injection. Percentage of total glucose infused from 0 to 4 hours is summarized.
5. Number of Treatment Emergent Adverse Events (TEAEs) Related to Study Drug [ Time Frame: first dose through 7 to 10 days after last dose ]
   The number of TEAEs related to study drug (as determined by the Investigator) are summarized. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.
