Type 1 Diabetes Clinical Trials

This is a single site, double-blind, placebo-controlled, crossover trial to quantify the effects of combination adjunctive therapy on glycemic control, ketogenesis during insulinopenia, insulin resistance, and diabetes burden and quality of life. Read Less

This single site investigator-initiated prospective observational study will enroll up to 150 participants 13-26 years of age with Type 1 diabetes (T1D) and utilize ecological momentary assessment methods (EMA) to examine associations between different diabetes psychological domains (distress, anxiety, and depression) in real-time on self-efficacy, self-management behaviors, and glycemic outcomes.

The purpose of this research study is to understand how type 1 diabetes (T1D) increases the risk for cardiovascular diseases (heart attack and stroke). To this end, the investigators will compare apolipoprotein and triglyceride kinetics in people wtih T1D and healthy control participants. Read Less

Patients with Type 1 Diabetes Mellitus (T1DM) have a higher risk of low-trauma (osteoporotic) fracture that is 7-12 times higher than non-diabetics. The bone density of people with Type 1 Diabetes is higher at the time of fracture than in non-diabetics. This suggests the presence of underlying bone tissue mechanical defects. The potential benefits to participants would be knowledge gained about their bone density and the results of laboratory tests. On a wider scale, there may be general benefits to society because the knowledge gained from this study may help better understand the effects of diabetes on bone health Read Less

The goal of this work is to conduct a randomized trial evaluating the effects of a behavioral intervention to increase sleep duration and quality for adolescents with type 1 diabetes (T1D). The impact of the sleep-promoting intervention on executive function and glycemic outcomes will be assessed. We will also explore multiple components of the recently identified central nervous system glymphatic system and evaluate how these components change and impact brain integrity and function with improved sleep.

Exercise is a cornerstone of diabetes management. It helps reduce blood pressure, promote weight loss, lower insulin resistance and improve glucose and lipid (triglyceride and HDL-cholesterol) profiles. Unfortunately, the benefits of exercise are often not embraced by diabetic individuals because of the fear of low blood sugar (hypoglycemia). My laboratory has demonstrated that Autonomic nervous system (ANS) counterregulatory failure plays an important role in exercise associated hypoglycemia in Type 1 DM. ANS responses are significantly reduced in Type 1 DM and are further blunted by antecedent episodes of hypoglycemia. Furthermore, there is a large sexual dimorphism of reduced ANS responses during submaximal exercise in both Type 1 DM and healthy individuals that is unexplained. Accumulating data are demonstrating that serotonergic pathways can regulate ANS discharge. Generally, serotonergic pathways are inhibitory but both single and longer term administration of selective serotonin reuptake inhibitors (SSRI's) such as Prozac has been demonstrated to increase basal epinephrine levels and enhance baroreflex control of Sympathetic nervous system (SNS) activity. What is unknown is whether fluoxetine can also enhance SNS responses and also override the large ANS sexual dimorphism present during sub maximal exercise. Therefore, the purpose of this study is to determine if the SSRI fluoxetine (Prozac) can improve SNS responses during exercise. Read Less

This research study will investigate whether dasiglucagon as a rescue therapy for participants under 6 years of age works and is safe to use. In addition, the study will investigate how dasiglucagon works in the body (pharmacokinetics and pharmacodynamics). Participants will receive 1 single dose as an injection under the skin (subcutaneous, s.c.) into the buttocks. Participants will have 3 visits with the study team. For each participant, the study will last up to 84 days. Read Less

The objective of this proposal is to demonstrate a viable, functionally integrated multivariable artificial pancreas (mvAP) that will address meal, physical activity (PA) and acute psychological stress (APS) challenges without any manual inputs to better regulate glucose levels of people with diabetes. Acute psychological stress and many other forms of PA besides planned exercise can affect blood glucose levels and cause challenges to maintaining euglycemia for people with type 1 diabetes mellitus (T1DM). Various PA and APS affect the metabolism and sensitivity to insulin in different ways. Hence, their types, intensities and durations, and their individual and concurrent presence must be detected in order to determine the optimal insulin administration. The mvAP approach provides a well-integrated and user-friendly technology with minimal burden on the user and mitigates the effects of unexpected PA and APS inducements. Twenty subjects with type 1 diabetes (ages 18-60) who use insulin pumps enrolled in this study. The study will take place at the UIC-College of Nursing Diabetes and Exercise Laboratory. The protocol will include 1 screening visit and 5 sessions at the laboratory. The primary activities at each meeting will include: (1) screening; (2) measurement of peak exercise capacity; (3) estimation of maximal strength from submaximal strength tests; (4) Trier Social Stress Test; (5) submaximal bouts of aerobic and resistance exercise, and activities of daily living with and without stress (e.g., mental calculations, video games). These activities will be included visit 3, 4 and 5 as appropriate. In addition, subjects will perform activities at home include: housekeeping chores, stationary bike (if available); treadmill (if available); walking; and light weights (if available). Periodically, the research assistant will call the subject during these times and ask them to perform stress-inducing activities while performing the activity. The stress inducing activities will include mental challenges such as a mathematical computation while performing the activity. The subjects will be called at home 3-5 times during the study. The fully automated algorithm will be tested in a home setting, however, the methodology will be developed and approved for testing later in the study. Read Less

The brief purpose of this research study is to learn about the safety and efficacy of intra-arterial administration of CELZ-201 in patients with newly diagnosed Type 1 Diabetes Mellitus (T1D). Read Less

The goal of this longitudinal cohort study is to learn about a mHealth intervention in Type 1 Diabetes (T1D) The main question\[s\] it aims to answer are: * Does the intervention increase the amount of text messages between the mHealth software and participants? * Do the text messages from the Nudge software increase moderate to vigorous physical activity (MVPA) in participants? * Does the MVPA encouraged by the Nudge software improve the HbA1c levels of participants? Participants will: * Receive text messages from the Nudge software * Report physical activity goals via the text messages to the Nudge software * Wear both an accelerometer and an actigraph for three weeks (spread out across the beginning, 30 days, and 90 days of participation) * Complete surveys at the beginning of participation * Complete daily surveys while wearing the devices * Complete surveys at the end of participation * Record physical activity in study surveys Read Less

This is a study to develop and evaluate a peer mentoring intervention for Black and Latinx adolescents with type 1 diabetes to increase the initiation and maintenance of a continuous glucose monitoring (CGM) device. This device is a standard of care to improve diabetes management related to diet, exercise, and insulin. Use of CGM has been shown to improve health outcomes, but is not used by adolescents of color. Peer mentors may help improve usage. Read Less

This R01 is in response to RFA-DK-19-021, Treating Diabetes Distress to Improve Glycemic Outcomes in Type 1 Diabetes. The objective is to test the feasibility and acceptability of a novel, practical, and potentially scalable screen to treat program for diabetes distress in families of school-age children with T1D (called Remedy to Diabetes Distress \[R2D2\]) and to test the initial efficacy of R2D2 to reduce diabetes distress to improve children's glycemic control.
