Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators are doing this research study to compare the pharmacokinetics (PK) (rate of absorption) of insulin lispro (Humalog), insulin aspart (Novolog), and insulin glulisine (Apidra) within individual subjects.

Additionally, the investigators will perform a preliminary feasibility evaluation of a minimally invasive continuous insulin monitoring (CIM) device and its use to derive PK parameters in human subjects.

Intervention Model

SINGLE_GROUP

All subjects participated in the single arm of the study. Some subjects participated in the continuous insulin monitoring sub-study in addition to the main protocol, or separate from the main protocol.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Multiplex pharmacokinetic profiling

Multiplex pharmacokinetic profiling of regular human insulin, insulin aspart, insulin lispro, insulin glulisine, and regular human insulin. All subjects participated in the single study arm and received injections of each type of insulin. Blood samples were drawn at intervals for pharmacokinetic profiling.

Group Type EXPERIMENTAL

Multiplex pharmacokinetic profiling

Intervention Type OTHER

Continuous insulin monitoring

Continuous insulin monitoring (CIM) of insulin lispro. Some subjects participated in the CIM sub-study, which is distinct from the Multiplex Pharmacokinetic Profiling study. This intervention involved administering insulin lispro and monitoring pharmacokinetic profile of the drug using blood samples and an investigational continuous insulin monitoring system.
