NCT07667504
Although type 1 diabetes (T1D) has traditionally been considered a disease associated with a lean phenotype, it is estimated that up to 2 out of 3 people living with T1D are overweight or obese, factors linked to an increased risk of complications in these patients. The available evidence regarding nutritional strategies for weight loss in T1D is very limited, and clinical trials are needed to determine how to effectively and safely promote weight loss in this population. In recent years, low-carbohydrate diets and several intermittent fasting protocols have demonstrated efficacy in promoting weight loss both in patients with type 2 diabetes and in patients with obesity without diabetes. In this study, we will evaluate the efficacy of moderate carbohydrate restriction, time-restricted eating, and standard calorie restriction for weight loss in adults with T1D and overweight/obesity.
NCT07011147
The goal of this randomized controlled trial is to compare the efficacy and safety of the iLet Bionic Pancreas (BP) System in adults with insulin-treated diabetes (type 1 diabetes or type 2 diabetes) compared to standard of care when ordered by primary care providers. The main question it aims to answer is: Can the iLet BP by deployed in primary care settings to adults with insulin-treated diabetes (type 1 diabetes or type 2 diabetes)? Researchers will compare 13-weeks of iLet BP use to routine care to see if iLet BP use has a greater reduction in HbA1c compared to13-weeks of routine care. Participants will: Use the iLet BP for 13-weeks or continue their routine care Be trained to use the study devices or continue their routine care Complete a virtual screening visit, mid-period follow up calls and a final visit Complete baseline CGM collection Complete surveys and fingerstick a1c blood tests Routine care participants will have the option to complete an observational extension phase where they will wear the iLet BP for 13-weeks
NCT06883344
The goal of this clinical trial is learn if automated insulin delivery (AID) systems can be used for glucose management during labor/delivery for pregnant people with type 1 diabetes (T1D). The main questions this study aims to answer are * What are the neonatal glycemic outcomes with use of AID systems during labor/delivery? * Do patients report higher birth satisfaction with use of AID systems during labor/delivery? * Are glycemic parameters like time-in-range (TIR) better with use of AID systems during labor/delivery? Researchers will compare AID systems to intravenous (IV) insulin (the current standard of care for glucose management during labor/delivery) by randomly assigning participants to one or the other.
NCT07401901
The purpose of the study is to evaluate the safety and the effectiveness of the Novel Medtronic Experimental Automated Insulin Delivery system, named MiniMed NMX8 system (referred also to as NMX8 system), in comparison with other commercially available AID systems (Automated insulin delivery) in adult patients with Type 1 diabetes not achieving target clinical outcomes.
NCT06815081
Type 1 diabetes (T1D) is a chronic condition, affecting 1 in 490 children under the age of 15 years. It is caused by the immune system damaging the pancreas, the organ which makes insulin. T1D has recognised stages before symptoms develop, providing an opportunity for early diagnosis, education and treatment which may delay the onset of symptoms. Type 2 diabetes (T2D) is also a chronic condition where the body cannot make enough insulin, or cannot respond to the insulin properly. It is usually related to obesity, rather than an immune problem. It is more common in adults, but the early stages often start in childhood (up to 1 in 4 children in some clinics). Like T1D, early detection can delay onset of T2D, or even prevent it altogether. Early diagnosis of T1D or T2D often relies on a test called the oral glucose tolerance test (OGTT), which is commonly used but not well tolerated, possibly because it requires a drip inserted into the vein, and several blood samples taken over 2-3 hours in a healthcare setting. Our study aims to test whether we can do an OGTT using a finger-prick to test glucose, at home. We call this the 'GTT@home'. The finger-prick creates a drop of blood, which is done before and two hours after drinking a sugary drink. We will also explore whether a continuous glucose monitor (CGM), which reads glucose levels through the skin could be an alternative. We plan to recruit 90 children and young people, across two groups to assess the GTT@home. To understand the experiences of those involved in monitoring, we will invite young people, parents and healthcare workers to take part in an interview, to understand the impact of testing to predict clinical T1D. Group 1 will assess the accuracy of measuring glucose from a finger-prick blood test when compared to a blood test from the vein. We will recruit individuals who are having an OGTT as part of a research study, for clinical care or if they have agreed to have an OGTT for this study. Those with T1D will be invited to wear a CGM to explore its use as an additional, practical alternative. Groups 2 and 3 will assess how well the GTT@home test works when done at home and how acceptable it is. This will only be offered to those known to be at risk of T1D. These studies will help us to understand if the GTT@home can be used in routine care.

This is a first-in-human (FIH) study designed to assess the safety, tolerability, and pharmacokinetic (PK) profile of IMC-S118AI in single-ascending dose (SAD) and multiple-ascending dose (MAD) regimens. This study will potentially also explore the effects of multiple-dosing regimens on preservation of beta-cell function in Stage 3 Type 1 diabetes.
NCT07482488
The goal of this study is to evaluate the feasibility and acceptability of a school nurse focused e-Learning application to improve their diabetes device knowledge and confidence. School nurses will be asked to complete pre-/post-surveys around a 16-week curriculum.
NCT07322380
The aim of this study will be to evaluate the feasibility of an autoantibody-based type 1 diabetes screening program for first degree relatives of people living with type 1 diabetes within the province of Quebec. Feasibility of follow-up strategies of "at-risk" individuals will also be assessed. This project will be divided into two phases, with the aim to evaluate: 1. The feasibility of a IAb (islet antibody)-based screening process for first degree relatives of people living with type 1 diabetes (T1D). 2. The feasibility of two approaches for follow-up monitoring in case of positive screening: centralized (within the organization) and decentralized approach (relying on individuals' healthcare providers), in the Quebec province setting. Participants will come to the laboratory for blood sample collection, medical history and genetic risk score assessment, as well as anthropometric and cutaneous advanced glycated end (AGE) products measurements. A series of questionnaires will be completed. After screening results are obtained (i.e., presence or absence of IAbs), a virtual visit will be conducted to communicate results to participants. A positive result for IAb will warrant a second test for confirmation , using WBD within 3 months of initial screening. After IAb positivity confirmation, participants will be invited to participate in phase 2 of this project (monitoring). Participants will be given the opportunity to select either a centralized or decentralized path for study monitoring. Follow-up will be dependent of the stage of T1D: * Participants in pre-stage 1 or stage 1 (2 or more positive IAbs without dysglycemia) T1D will receive a follow-up phone call six months after the initial screening. * Participants in stage 2 (2 or more positive IAbs with dysglycemia) will be contacted one month after screening.

NCT07341243
A randomised, crossover, counterbalanced repeated measures study will be conducted to examine the effect of acute heat exposure on rate of change in blood glucose concentration during 40 minutes of moderate-intensity exercise and for 30 minutes after exercise. Participants will complete two experimental conditions during two separate laboratory visits, with the order of conditions randomised. One condition will be a temperate condition of 20°C with 50% relative humidity (Temperate), the other will be 40°C with 50% relative humidity (Heat). Visits will be identical, including time of day, except for the condition. Visits will be separated by 24h. Testing will take place in the laboratories of the Research Institute for Sport and Exercise Sciences at Liverpool John Moores University.
NCT06752369
The goal of this clinical trial is to learn if implementing a single-session depression intervention for youth with type 1 diabetes (T1D) is feasible and acceptable to patients. can help improve mood and health outcomes. It will also learn about the initial efficacy of the intervention. The main questions it aims to answer are: 1. Is a single-session depression intervention for youth with T1D feasible to recruit and implement? 2. Is a single-session depression intervention for youth with T1D acceptable to patients (i.e., do they find it helpful)? 3. Does a single-session depression intervention for youth with T1D lead to improvements in low mood? Researchers will compare a single-session depression intervention for youth with to a education control to see if a single-session depression intervention works to improve depressive symptoms. Participants will: * Participate in a single-session depression intervention * Complete questionnaires and provide a sample for A1c at a baseline, 3-month, and 6-month visit * Complete daily questionnaires once a day for two weeks before and after the single-session depression intervention
NCT07290868
The Diactive-1 project aims to establish the Diactive-1 mobile application as a clinical tool for managing type 1 diabetes in children and adolescents in several hospitals from Spain. The successful implementation of the app in new healthcare centers nationwide represents a key step toward the development of a comprehensive and scalable program. This approach seeks not only to optimize current patient care but also to democratize access to an innovative, evidence-based intervention that supports daily diabetes management. In this new phase, the project will integrate the application into routine clinical care for patients with type 1 diabetes through the use of a simple handgrip strength measurement. A dedicated web platform (www.diactive.es) is being developed to allow clinicians to enter basic patient data, including handgrip strength, sex, and email address. Based on this information, the system will automatically generate a personalized download link for the Diactive-1 app, accompanied by tailored guidance and an initial fitness level classification (low, medium, or high) according to European reference values. This process will define each user's baseline fitness level and facilitate the use of Diactive-1 as an integrated and individualized disease management tool. The ultimate goal is to strengthen clinical decision-making, improve patient engagement, and extend the benefits of digital health to a broader pediatric population living with type 1 diabetes.
NCT07286019
The goal of this interventional study is to build a high quality, real world multimodal dataset that combines continuous glucose monitoring (CGM), wearable and fitness data, performance metrics, and saliva and urine omics collected during a prolonged, moderate intensity outdoor gravel-cycling session in adults with type 1 diabetes (T1D). The main questions it aims to answer are: * Can we collect and synchronize comprehensive CGM, physiological, performance, and omics data around a single cycling session to enable further artificial intelligence (AI) model development? * What molecular changes in saliva and urine occur during exercise, and how do they relate to glycemic outcomes? Participants will: * Complete a supervised \~75 km gravel-cycling route at their own pace under real-world conditions, without protocolized therapy adjustments. * Wear a Dexcom G7 starting \~4 days before the ride and continue through the sensor lifespan to capture CGM data. * Provide saliva and urine immediately before and after the ride for epigenomic and proteomic analyses. This study will generate an integrated resource that supports the development and validation of AI models for predicting glucose responses to exercise in T1D and will help guide future studies on how prolonged exercise affects glucose control.
NCT07286500
This observational study examines whether sexual activity influences the risk of hypoglycemia in adults with type 1 or type 2 diabetes treated with insulin therapy and using continuous glucose monitoring (CGM). Many patients report fear of hypoglycemia during or after sexual activity, which may affect their quality of life and willingness to engage in intimate relationships. However, no systematic research has been conducted on this topic, largely due to the sensitive nature of sexual health and the previous lack of tools to remotely monitor glucose profiles. The study uses CGM systems (LibreView or Dexcom Clarity) to evaluate glucose changes during and up to 6 hours after sexual activity. Participants will mark the start of sexual activity in their CGM application using a neutral symbol (such as a heart icon). Data will be collected remotely through secure, certified platforms without the need for discussing details of intimate life. Glucose profiles from days with and without sexual activity will be compared. Each participant will be observed for 3 months. The study will include 100 adults with type 1 or type 2 diabetes who use CGM and insulin therapy. By analyzing episodes of glucose levels below 70 mg/dL during or after sexual activity, the study aims to determine whether sexual activity is associated with an increased risk of hypoglycemia. Findings may help to better understand patient concerns, reduce unnecessary fear, and develop future clinical recommendations for safe sexual activity in individuals treated with insulin.
NCT06967701
The challenges of living with type 1 diabetes often stand in the way of getting enough exercise. Continuous blood sugar monitoring has revolutionized type 1 diabetes care but remains underutilized to sustainably support exercise and related behaviors. This remote participation-based research will develop a mobile application that delivers personalized encouragement and data-driven health insights based upon patterns in blood sugar, exercise, mood, and sleep, to assist people with type 1 diabetes in exercising more frequently and confidently. You do not need to live in Connecticut to participate, as there will be no required in-person visits during the study.
NCT07185555
Overweight and obesity are frequent in adults with type 1 diabetes (T1D), with prevalence exceeding 50% in recent studies. Excess weight in T1D is associated with higher cardiometabolic risk and therapeutic challenges, while effective and safe weight management strategies are still limited. This single-center, single-arm feasibility study will evaluate the efficacy and safety of a Very Low-Energy Ketogenic Therapy (VLEKT; 600-800 kcal/day) in adults with T1D and obesity treated with Advanced Hybrid Closed Loop (AHCL) insulin delivery systems. Participants will follow a structured 4-week program with commercial very-low-carbohydrate, high-protein meal replacements, under close medical supervision. The primary endpoint is change in body weight at 4 weeks. Secondary outcomes include body composition, muscle strength, glucose metrics, insulin requirements, biochemical parameters, and patient-reported outcomes. Safety will be assessed through hypoglycemia incidence, ketone monitoring, and occurrence of diabetic ketoacidosis (DKA). The study will enroll 14 participants. It is expected that VLEKT will achieve \~5% weight loss within one month while maintaining glycemic safety under AHCL technology.
NCT06728423
Patients meeting the inclusion criteria will be identified. An informed consent form will be completed. Clinical data and baseline CGM will be collected at this appointment. During the session, an attempt will be made to establish a physical activity classification (PA0: inactive, PA1: 1-2 times per week, and PA2: more than twice per week) to determine if the patient is physically active, which is defined as at least 60 minutes of physical activity per week during the past 6 months. In addition, the patient will be asked whether or not they perform strength exercises and how regularly they do so. At the end of the first visit, they will be randomized by an electronically generated numerical sequence using the Randomizer for Clinical Trial Lite application. The patient will be scheduled to attend a supervised exercise session at the Pontificia Universidad Javeriana Sports Training Center. Participants will have a blood glucose test prior to beginning physical activity. The target for starting exercise is 126-180 mg/dl. If the patient has a value less than 90 mg/dl, 20 grams of carbohydrates will be given; if the value is between 90-126 mg/dl, 10 grams will be given (above the investigators said that for anaerobics it could be from 90 mg/dl). If the value is higher than 200 mg/dl, the correction with rapid insulin is calculated according to your usual management. A new glucose test is performed 15 minutes later to confirm that the patient is within the target range. If the patient is within the target range, exercise is performed. If the reading remains above 200, the exercise session is canceled. All participants are in SmartGuard mode on the Minimed 780G system. In the control group, the time target is activated 60 minutes before the activity and turned off 15 minutes after the end of the exercise. Participants randomized to SmartGuard will have no changes in device programming. Glucose measurements will be taken at the beginning and end of the exercise session. In addition, a Hooper Index will be calculated to standardize the patient's rest and recovery prior to the session. The strength training session will begin with a brief 15-minute warm-up emphasizing joint flexibility. The workout will consist of 3 sets of 10 repetitions of the following exercises: leg press, chest press, seated row. The estimated weight at which the exercises will be performed will be 60-80% of the 1-RM calculated for each patient. There will be a 90 second timed rest between each set of exercises. The total duration of the training will be 45 minutes. The strength training session begins with a short 15-minute warm-up focusing on joint flexibility. The workout consists of 3 sets of 10 repetitions of the following exercises: leg press, chest press, seated row. The estimated weight at which the exercises are performed is 60-80% of the 1-RM calculated for each patient. A timed rest of 90 seconds will be provided between each set of exercises. The total duration of the training will be 45 minutes. The parameter used to monitor intensity will correspond to the Borg scale measurement and heart rate monitoring. For each participant, the anthropometric variables will be entered into the application in order to perform the exact calculation of the target maximum heart rate (HR) percentage. The activity begins with a 5-minute warm-up at low intensity (55-65% of maximum HR, Borg 9-11), then 35 minutes at moderate intensity (70-80% of maximum HR, Borg 12-13), and ends with a 5-minute cool-down (maximum HR less than 55%). Alarms are set on the device to maintain the desired intensity. Glucose testing is performed at the beginning and end of the activity. A 14-day washout period will be carried out, after which the group of patients initially assigned to temporary target activation will perform the same exercise in SmartGuard mode; likewise, the group initially assigned to SmartGuard will do so under temporary target mode. For this second session, the same procedure and recommendations already mentioned will be carried out. CGM data will be collected through integrated continuous glucose monitoring, which downloads the information to the Carelink portal and is accessed online.

Glycemic control metrics were compared between the preoperative, intraoperative, and postoperative periods using a paired t test. Finally, a subgroup analysis was performed based on the type of procedure, percentage of sensor use, and duration of diabetes.
NCT07148076
Type 1 diabetes is a chronic autoimmune disease that requires continuous monitoring and regulation of glycemia. Children with type 1 diabetes face challenges that can disrupt their daily routines in school and kindergarten. This includes the need for self-monitoring, continuous blood sugar measurement, insulin administration, proper nutrition, regular physical activity, and timely interventions in cases of hypoglycemia or hyperglycemia. Therefore, children with diabetes often require support from educational staff, including teachers, preschool educators, and other professional personnel while attending educational institutions. A safe and supportive (pre)school environment is crucial for maintaining the health and well-being of children with type 1 diabetes. Teachers and preschool educators, as key actors in the daily (pre)school life of the child, play an important role in recognizing disease symptoms and managing emergencies. However, research shows that many teachers lack sufficient knowledge about the symptoms of diabetes and the necessary procedures in emergencies, which can endanger the health and safety of the child, as well as their equal participation in educational activities.
