研究概览
简要总结
The purpose of this study is to collect confirmatory clinical data to support 6 or 7 days wear of EWIS (Extended Wear Infusion Set).
详细描述
This study is a multi-center, non-randomized, prospective single arm study with Type 1 patients with diabetes on insulin pump therapy with Continuous Glucose Monitoring (CGM). A total of up to 300 subjects age 18-80 will be enrolled at up to 20 investigational centers in the US. Each subject will wear their own MiniMed™ 670G insulin system. Each subject will be given 12 infusion sets to wear (each infusion set for at least 174 hours, or until infusion set failure if this occurs before 174 hours). Subjects will change insulin reservoirs at least every 174 hours. The time of infusion set insertion will be taken from Daily Log. Subjects can expect to participate for approximately 12-16 weeks.

入选标准
- •Subject is age 18 - 80 years at the time of screening
- •Subject has type 1 diabetes for more than one year Study specific inclusion criteria

- •Subject is willing and able to perform study procedures as per investigator discretion
- •Subject is willing to take one of the following insulins and can financially support the use of either of the 2 insulin preparations throughout the course of the study (i.e. co-payments for insulin with insurance or able to pay full amount):
- •Humalog™* (insulin lispro injection)
- •NovoLog™* (insulin aspart)
排除标准
- •Subject is actively participating in an investigational study (drug or device) wherein he/she has received treatment from an investigational study drug or investigational study device in the last 2 weeks.
- •Subject is female and has a positive pregnancy screening test
