Inter-Arm Differences in Continuous Glucose Monitor Readings in Adults With Diabetes

2026年11月1日 更新者：Sachin Shah、University of the Pacific

Evaluation of Inter-Arm Differences in Continuous Glucose Monitor Glucose Readings in Patients With Type 1 and Type 2 Diabetes

This is a clinical trial looking at differences in continuous glucose monitor (CGM) glucose readings between the left and right arms in adults with type 1 or type 2 diabetes. The study will enroll 60 participants who will wear a CGM sensor on both arms for 14 days.

详细说明

This study is a prospective, non-randomized clinical trial designed to evaluate differences in continuous glucose monitor (CGM) glucose readings between the left and right arms in adults with type 1 or type 2 diabetes.

The study will enroll 60 participants. Each participant will wear two FreeStyle Libre 3 Plus CGM sensors simultaneously for 14 days, with one sensor placed on each arm.

The primary objective is to compare the frequency of hypoglycemic events, defined as glucose readings below 70 mg/dL, between the left and right arms. Secondary analyses will evaluate differences in Level 1 and Level 2 hypoglycemia and time below range. Additional analyses will compare time in range, time above range, time below range, and average glucose between the two arms.

CGM data from the two sensors will be collected and compared to evaluate differences in glucose readings between the left and right arms.

描述

Inclusion Criteria:

  • Adults 18 years of age and over
  • Diagnosed with type 1 or 2 diabetes mellitus
  • Female participants with childbearing potential must have a negative urine pregnancy stick test, which has been confirmed by investigators
  • Willingness to wear a CGM on each arm for 2 weeks
  • A1c <7% within the past 6 months
  • Willing to attend 3 virtual call meetings over the course of the trial
  • Have active health insurance throughout the duration of the study
  • Willing to refrain from consuming or using commercial products containing ascorbic acid (vitamin C) or salicylic acid, and certain skincare products for the duration of the study due to their known potential to interfere with CGM readings (exposure via food is allowed)
  • Participants must have a mobile phone that is connected to the internet and compatible with both "FreeStyle Libre 3" and "Libre by Abbott" apps

Exclusion Criteria:

  • Under the age of 18

  • Currently taking hydroxyurea
  • History of or planned gastric bypass within the study period
  • Current systemic infections
  • Subjects who are unable to fully understand the study or consent process will not be included in the study due to the lack of a qualified medical translator

武器和干预

参与者组/臂
干预/治疗
实验性的：Left and Right Arm CGM Wear

Participants will wear two FreeStyle Libre 3 Plus continuous glucose monitors (CGMs) simultaneously for 14 days, with one sensor applied to the back of the upper arm on each arm. Participants will continue their normal daily routine during the study period. CGM data from the left and right arms will be compared.
设备：FreeStyle Libre 3 Plus Continuous Glucose Monitor

Two FreeStyle Libre 3 Plus continuous glucose monitors (CGMs) will be worn simultaneously for 14 days. One sensor will be applied subcutaneously to the back of the upper arm on each arm. The sensors measure glucose in the interstitial fluid, and data from the left and right arms will be collected and compared.
