Type 1 diabetes clinical trials — recruiting now

Research has shown a link between poor sleep health and late circadian timing with cardiometabolic health in adolescents with type 1 diabetes (T1D). Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in T1D, which begins as early as adolescence, and current therapies are limited. Therefore, this study plans to investigate whether cardiometabolic health can be improved with increased sleep duration and advanced circadian timing in adolescents with T1D with habitually insufficient sleep. To answer this question, investigators will study adolescents with T1D who get \<7h sleep on school nights and measure changes in insulin sensitivity, glycemic control, and vascular function after one month of a sleep and circadian intervention (1+ hour longer time in bed each night plus evening melatonin and morning light therapy) compared to one month of typical sleep (usual school schedule).

This is a study to evaluate the HLA-DRB1\*04:01 genotype in adults that have been diagnosed with type 1 diabetes

Mental conditions and disorders (e.g. distress, depressive, anxiety, and eating disorders) are more prevalent in people with diabetes (PWD) and associated with reduced quality of life and impaired glycaemic outcomes. Evidence supports a complex network between psychosocial factors and glycaemic control that can be highly variable between persons. It is assumed that subgroups exist that show different trajectories of glycaemia and mental health. Belonging to a particular subgroup may be linked with a higher risk of developing mental health problems compared to others. This suggests that it is possible to treat individuals in different subgroups in a manner that optimizes their treatment and can improve health outcomes. Accurate characterisation can inform more individualized care. This calls for a more personalised approach considering the idiosyncrasies of different subgroups. Over 3 years, the investigators have established the basis of a precision mental health approach for diabetes using n-of-1 analyses. By utilizing combined ecological momentary assessment (EMA: repeated daily sampling of psychosocial factors in everyday life) and continuous glucose monitoring (CGM), intensive longitudinal data per person could be collected. This enables the analysis of individual associations between glycaemic parameters and psychosocial variables and identification of individual sources of diabetes distress in each person. The objective of the present study is to use of the n-of-1 approach to identify subgroups of PWD who share common characteristics in the associations between glucose and psychosocial variables. The identified subgroups shall be used to develop a digital twin for precision mental health in diabetes. The digital twin serves as representation of a real person, allowing to make simulations and predictions of the course of mental health and glycaemia. These predictions can inform diabetes care and lead to more precise, personalised treatment decisions. To achieve this, a longitudinal panel including over 1,400 PWD who continuously complete EMA and questionnaire surveys and measure glucose levels using CGM was developed. Over 1000 clinical interviews to diagnose mental disorders have been conducted to identify major mental health conditions and map mental outcomes. To identify subgroups and develop the digital twin, the sampling will be expanded aiming at a total of 1,809 PWD. Incidence and remission of mental disorders will be determined via repeated interviews. The complex networks between clinical, metabolic, and psychosocial data will be analysed using machine learning, leading to new insights with the potential to shape future guidelines. These results will be used by the digital twin to predict courses of glycaemic control and mental health, translating the individual evidence into direct treatment suggestions.

Diabetes mellitus (T2DM) is the most common complication of obesity patients. According to previous literature reports, weight loss and metabolic surgery are powerful means to treat obesity complicated with T2DM. Roux-en-Y gastric bypass (RYGB) is the standard operation recommended by the international society. One-anastomosis gastric bypass (OAGB) was recommended by IFSO（the International Federation for the Surgery of OBESITY AND METABOLIC DISORDERS ） in 2018. In this study, two kinds of metabolic surgery will be compared. At present, focusing on the above two operations, only two effective randomized controlled clinical studies have been carried out, among which one single-center clinical study has been followed up for 2 years, and the primary end point is weight loss; Another multicenter study, with a 2-year follow-up, showed that the primary end point was weight loss, and the secondary index was the effectiveness of two surgical methods in the treatment of T2DM.There is still a lack of evidence-based evidence for the effectiveness and safety of the two surgical methods in the treatment of T2DM. This study will make high-level evidence about the advantages and disadvantages of OAGB and RYGB in the treatment of T2DM. In this study, a number of centers with rich experience and clinical research experience in weight loss and metabolic surgery in Asia will be combined to complete the enrollment of 248 patients. Those who meet the standards will be randomly divided into two kinds of operations, and they will be followed up for 5 years on schedule. The rate of lost follow-up is controlled within 20%, and the data integrity is controlled within 95%. Taking the blood glucose remission rate of type 2 diabetes as the main observation index, the prospective verification shows that OAGB is clinically effective in treating obesity with type 2 diabetes compared with RYGB.

This is a multi-center, prospective, non-interventional study that focuses on the long- term effects following participation in selected ITN new-onset Type1 Diabetes Mellitus studies with immunomodulatory agents (T1DM, T1D). This observational study will: * follow participants to determine how long they continue to produce insulin, and * will also assess how changes in the immune system over time relate to the ability to produce insulin. This information could help design better therapies for type 1 diabetes in the future.

Type 1 diabetes (T1D) affects approximately 2 million Americans, and only 2 in 8 young adults ages 18-31 years achieve glycemic targets (glycated hemoglobin A1C \<7.0%). Achieving glycemic targets is associated with reduced risk of micro-and macrovascular complications. Sleep deprivation leads to impaired glucose tolerance and insulin sensitivity in adults without chronic conditions and with T1D. Promoting sleep in laboratory and natural environments contributes to improvements in insulin sensitivity, glucose levels, and distress symptoms in young adults without chronic conditions and more time in range in adolescents with T1D. Multiple dimensions of sleep health (alertness, timing, efficiency, and sleep duration) are associated with better achievement of glycemic targets in adults with T1D. Therefore, sleep health dimensions are appropriate therapeutic targets to improve glucoregulation and other diabetes self-management outcomes in this population. Our primary objective is to evaluate the immediate and short-term effects of a 12-week CB-sleep intervention compared to enhanced usual care (time balanced attention control) on actigraphy- and self-report derived sleep health dimensions and diabetes self-management outcomes (glycemia and distress symptoms) over 9-months (Stage II of the NIH Model for Behavior Change, ORBIT phase III). CB-sleep is guided by principles and practices from motivational interviewing and the Transtheoretical Model of Behavior Change with interactive stage-matched sessions.

This is a 17 - week study consisting of a one - week run - in period and a 16 - week intervention. The 16 - week pilot interventions aims to increase hydration in those beginning GLP - 1 RA therapy. Investigators aim to increase hydration to potentially decrease side effect severity, amount of side effects, and drug discontinuation associated with GLP - 1 RA therapy. The investigators are piloting to assess feasibility and preliminary efficacy of the intervention through examining participant retention, participant feedback, researcher and participant adherence to protocols, impact on hydration biomarkers, and participant reported GLP - 1 RA side effects.

Monocentric interventional prospective study to evaluate the prevalence of sarcopenia in adults with type 1 diabetes (T1DM) and to evaluate the association between diabetic neuropathy and sarcopenia in subjects with T1DM; to evaluate the prevalence of dynapenia in adults with T1DM and its association with diabetic neuropathy.

The REMODAL trial is a randomized crossover study aiming to update treatment guidelines for mild hypoglycemia in people with Type 1 diabetes using continuous glucose monitoring (CGM) technology. The study will assess whether treating mild hypoglycemia proactively (at a glucose threshold of 5.0 mmol/L) with lower doses of carbohydrate (CHO) is more effective than the traditional reactive approach (treatment at \< 4.0 mmol/L). The goal is to reduce hypoglycemia frequency and improve quality of life, while minimizing caloric intake and rebound hyperglycemia.

This study aims to evaluate the effects of animated films and story books on the fear and anxiety levels of children with newly diagnosed type 1 diabetes.

Traditional diabetes therapies focus on improving blood sugar control. However, many studies show that this may not be enough. New treatments focusing on weight loss have heralded better results. One of these treatments is Semaglutide and the investigators wish to examine its effects further in this study. The investigators propose to investigate what happens to the fat inside the heart and the leg muscles.

This study seeks to address the multifaceted challenges posed by food disparities and their negative consequences on health outcomes, via a comprehensive community health intervention program. Study objectives include: 1. To describe the social-demographic and clinical factors associated with food insecurity in the hospitalized diabetic population. 2. To design, implement and evaluate a nutrition program targeting the hospitalized diabetic population. The investigators will prospectively randomize the target population into either a nutrition program (Intervention), or state-of-art standard of care (SOC) in a 4:1 ratio. Participants in the intervention group will be provided the following two resources in addition to SOC: 1) Enhanced access to nutritious food (twice daily meal delivery up to 90 days post-discharge) 2) Education at discharge and continuing outreach to enhance knowledge for better diet and food options. 3. To enhance community engagement and develop a systematic implementation plan for long-term roll-out of the nutrition program.

This study took FT1D（fulminant type 1 diabetes） as the research object, collected the cases of FT1D patients, and described the clinical characteristics of this type of disease. The HLA susceptibility genes of FT1D were identified by PCR and other techniques, taking age-sex-matched healthy subjects as controls and HLA genes as the research entry point.

The goal of this clinical study is to learn more about the study drug, GS-4571, and how safe it is in 3 groups, i) Healthy participants, ii) Healthy non-diabetic obese participants, and iii) Non-obese participants with Type 2 Diabetes Mellitus (T2DM). The primary objectives of this study are: * To characterize the pharmacokinetics (PK) of GS-4571 following single and multiple ascending oral doses of GS-4571. * To evaluate the effect of concomitant food intake and (if conducted) a representative acid-reducing agent (proton pump inhibitor (PPI), omeprazole) on the PK of GS-4571. * To evaluate the safety and tolerability of single and multiple ascending oral doses of GS-4571.

The goal of this clinical trial is to learn about the effect of the study drug (ZT-01) on low blood sugar (hypoglycemia) in adults with type 1 diabetes (T1D) who have been having low blood sugars ("hypos") at night. ZT-01 increases the amount of a hormone called glucagon during low blood sugar, and this may help prevent the occurrence of hypos. The main questions this trial aims to answer are whether ZT-01 lowers the number of hypos happening at night, and what its effects are on blood sugar levels. The safety of ZT-01 will also be measured. Participants will be asked to wear a study-provided continuous glucose monitor (CGM) during two 4-week periods when they will self-inject the study drug before bed. They will get ZT-01 at one of three dose levels during one period, and placebo (which looks like the study drug but doesn't contain the active ingredient) during the other. Neither the participant nor the study site will know what they are receiving during each treatment period or see data from the CGM. The participant will continue to use their usual methods of measuring blood sugar (including their personal CGM) and giving insulin during the study. The participant will be asked to complete a short diary each evening, and will be asked to upload the CGM data to a study phone every day. If a participant uses their own CGM and is willing to share information on how often they have low blood sugar with the study site at the first visit to see if they meet study entry requirements, they will have 6 study visits, 2 study phone calls, and be in the study for about 16 weeks. If they don't use CGM or don't want to share their information, then they will be asked to wear a study CGM for an extra 4 weeks to find out how many low blood sugars they have, and will have an extra visit. Study participants will be asked to give blood and urine for testing to see whether they meet the requirements to enter the study, and at the start and end of each treatment period to see if the study treatment has any effects. They will also have their blood pressure and temperature taken at each study visit, and have an ECG at 4 visits to measure the electrical activity of their heart. Some participants will be asked to also take part in a sub-study where their blood level of ZT-01 and glucagon is measured, after the first and last dose. They will be asked to stay at the study site overnight for each set of measurements (4 in total).

The aim of this observational study is to assess the effectiveness of automatic insulin infusion in responding to changes in insulin sensitivity throughout various phases of the menstrual cycle in a cohort of reproductive-aged women with type 1 diabetes, using an advanced closed-loop system. By gaining insights into both the limitations and effectiveness of this adaptation, we aim to inform the enhancement of control algorithms and learning strategies within closed-loop systems. This research is especially vital for addressing the distinct challenges that women commonly encounter in maintaining glycemic control.

Cardiovascular disease is a complication of type 1 diabetes (T1D), a life-long disease, usually diagnosed in childhood. The goal of this project is to determine the timing and factors leading to vascular damage in children from T1D diagnosis.

This study will evaluate the safety, tolerability and efficacy of VX-880 infusion in participants with Type 1 diabetes (T1D) and impaired awareness of hypoglycemia (IAH) and severe hypoglycemia.

Randomized, Placebo-controlled Study to determine the safety and tolerability of multiple oral doses of TIX100 administered daily for 28 days to otherwise healthy overweight/obese subjects.

Purpose: To examine the effect of addition of combination therapy with dapagliflozin plus pioglitazone to insulin on glucose control and plasma ketone concentration in patients with type 1 diabetes (T1DM) Research Design: 120 patients with type 1 diabetes who otherwise are healthy constitute the study population. After screening, eligible subjects will start 4 week run in. At week 4, subjects will receive dapagliflozin for 12 weeks. At week 16, subjects will be randomized to receive in a double blind fashion pioglitazone or placebo for 16 weeks. Methods: the following techniques will be employed in the present study: (1) mixed meal tolerance test; (2) indirect calorimetry; (3) continuous glucose monitoring. Clinical Relevance: the results of the present study will demonstrate that the addition of pioglitazone to SGLT2 inhibitor in T1DM patients produces greater reduction in the HbA1c without increasing risk of ketoacidosis and hypoglycemia.
