Randomized, Double-blind, Crossover, Pharmacokinetic (PK) and Glucodynamic (GD) Study of Continuous Subcutaneous Insulin Infusion (CSII) in Participants With Type 1 Diabetes Mellitus (T1DM)

Halozyme Therapeutics45 enrolled

Overview

The purpose of this study is to determine if recombinant human hyaluronidase PH20 (rHuPH20) will change the exposure and action of approved insulin analogs when given by continuous subcutaneous insulin infusion (CSII) in participants with Type 1 diabetes mellitus (T1DM). This study is divided into Stage 1, 2, and 3. Stage 3 was started chronologically before Stage 2 and, prior to performing Stage 2, the Sponsor made the decision to terminate Stage 2. Stage 2 was not initiated due to a strategic business decision and termination was not based on safety or efficacy concerns. No participants were enrolled in Stage 2.
