Brief Summary

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

This randomized controlled trial will investigate whether use of continuous glucose monitoring (CGM) vs. usual care with self-monitored blood glucose 1) enhances glycemic control, 2) reduces hypoglycemia risk, and 3) improves quality of life, diabetes distress, and fear of hypoglycemia in hemodialysis patients with diabetes mellitus.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a parallel, two-arm randomized controlled trial comparing real-time CGM using Dexcom devices vs. usual care (self-monitored blood glucose 4-times/day) among 122 in-center hemodialysis patients with diabetes mellitus over a 12-week period. Our primary objective will be to determine the effects of CGM vs. usual care on glycemic control, defined by percent (%) of time in target glucose range (70-180 mg/dl). Our main and exploratory secondary objectives will be to determine the effects of CGM on CGM-indices of hypoglycemia, blood-based glycemic markers (HbA1c, glycated albumin, fructosamine), and patient-reported outcomes (health-related quality of life, diabetes distress, hypoglycemia fear). We will also evaluate feasibility endpoints by measuring CGM compliance during the intervention period and success/ease of implementing CGM training sessions among patients.

Study Groups

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

Continuous glucose monitoring (CGM) arm

During the intervention period, patients in the CGM arm will undergo continuous real-time "unblinded" CGM using Dexcom CGM devices.

Group Type EXPERIMENTAL

Continuous glucose monitoring (CGM)

Intervention Type DEVICE

Patients in the CGM arm will undergo continuous real-time "unblinded" CGM using Dexcom CGM devices.

Usual care arm

During the intervention period, patients in the usual care arm will conduct self-monitored blood glucose (SMBG) at least 4 times/day. At Weeks 6 and 12 of the intervention period, usual care arm patients will also undergo 10-days of blinded CGM data collection.

Group Type ACTIVE_COMPARATOR

Usual care (Self-monitored blood glucose)

Intervention Type DEVICE

Patients in the usual care arm will conduct self-monitored blood glucose at least 4 times/day.
