New Glucose Sensor Pediatric

Status Completed

Clinical Trial Summary

The purpose of this study is to assess performance of a new subcutaneous glucose sensor over a seven day sensor life when used with currently marketed Medtronic Diabetes devices. In addition performance of the new sensor will be calculated for use of the new sensor with proposed new devices using new calibration algorithms.

Clinical Trial Description

The first generation Medtronic MiniMed Subcutaneous Glucose Sensor (Sof-Sensor) was originally approved by the FDA for commercialization as part of the Continuous Glucose Monitoring System (CGMS) on June 15, 1999 (PMA 980022). The Sensor is composed of a microelectrode with a thin coating of glucose oxidase beneath several layers of biocompatible membrane. This same sensor was used as part of subsequent continuous glucose monitoring (CGM) systems, such as the Guardian REAL-Time and Paradigm REAL-Time sensor augmented insulin pump. The current configuration of sensor has undergone in vitro and in vivo testing. A new second-generation glucose sensor (herein referred to as the Comfort Sensor) has been developed. The first-generation glucose sensor was approved with reported sensor accuracy (MAD) of 18%; it was labeled for maximum use duration of 72 hours, using only the abdomen as an insertion site. The new sensor is shorter and has a smaller diameter, with a smaller gauge introducer needle. The new sensor inserter is designed to be used with the new sensor. The objectives of this study are to 1) Assess performance of the Comfort Sensor when used over a period of seven days with currently available devices, and 2) Assess performance of the Comfort Sensor when used over a period of seven days using new calibration algorithms (post-processed with algorithm for future devices). Accuracy data will be calculated based on comparing calibrated glucose sensor values to glucose meter values during in-home testing. The devices that will be used for gathering sensor data during this study will be: 1) the Comfort Sensor, 2) the MiniLink (Transmitter), and 3) the Guardian REAL-Time Display Device. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
