Bioavailability, Biopotency and Food Effect Study of SCD0503 Compared to Subcutaneous Regular Human Insulin

Reason for the study The participants have been diagnosed with type 1 diabetes and are being treated with standard insulin therapy. The sponsor of the study is developing a new insulin-based medicine that can be taken by mouth (orally). For this reason, the investigational product named SCD0503 is to be tested in the study. The sponsor wants to investigate the course of blood concentrations and the blood sugar-lowering effect of the investigational product and to find out whether SCD0503 is safe. Investigational product tested in this study The investigational product tested, SCD0503, is still under clinical evaluation and has not yet been approved for your treatment. The active ingredient is regular human insulin, which has been used for many years in approved medicines for the treatment of diabetes. SCD0503 is being used in humans for the first time in this study. Study procedures The study will last for approximately 1 to 4 months. During this time, the participant will come to the investigational site 8 times for visits. During 4 visits the participant will undergo a clamp examination. The blood sugar-lowering effect of the investigational product is determined using a clamp device, a computer-controlled device that maintains blood sugar at a constant level within the normal range. This is achieved by infusing a sugar solution. During 2 further visits the participant will have a meal test. During the meal test, the blood sugar-lowering effect of the investigational product is determined after intake of a standardized meal as breakfast. You will have catheters in your arms to take blood, measure your blood sugar level and to infuse glucose (sugar) or insulin, if needed. SCD0503 is compared with a regular human insulin already approved for the treatment of diabetes. The participant will receive SCD0503 and the comparator product during different visits to the investigational site. The participant will also receive a placebo together with the investigational or the comparator product. The placebo looks identical but contains no active ingredient. As the investigational product is administered orally and the comparator product is injected under the skin, two placebos are used in this study. The order of medications given will be decided by chance, using a pre-defined method called randomization (a procedure similar to flipping a coin). Neither the participant nor the study physician will know which of the 2 medicines is administered at the respective dosing occasion. However, in case of emergency, this information will be quickly available.

Type 1 Diabetes and Diabetes Distress

The goal of this clinical trial is to reduce diabetes distress in emerging adults (18-35 years) with type 1 diabetes and moderate-to-severe diabetes distress. The expectation is that a group-based psychological intervention (ACTnow) will not only reduce diabetes distress but also improve psychological well-being and glycemic outcomes. The intervention involves a multidisciplinary team, including nurses, psychologists, and physicians, and is designed in a format that can easily be integrated into future standard care. The main research questions are: * Does a group-based psychological intervention reduce diabetes distress? * Does a group-based psychological intervention improve psychological well-being and glycemic outcomes? Researchers will compare the group-based psychological intervention (arm 1) with a waitlist control group, which will receive the intervention after three months (arm 2). Participants will first attend a virtual screening interview with a psychologist or nurse to identify if they are eligible to participate in the study. After randomization, the intervention group receives six bi-weekly sessions, each lasting two hours, led by a psychologist and nurse. Each session includes a mindfulness exercise, a review of the previous session, a new topic, individual homework assignments, and a conclusion.

HOME-AHCL: Home-Based Implementation of an Advanced Hybrid Closed-Loop System With Telemonitoring in Type 1 Diabetes

The goal of this observational study is to evaluate a new home-based setup and care model for an advanced hybrid closed-loop insulin pump system (Tandem with Control-IQ). The study will look at the safety, effectiveness, costs, and impact on quality of life in adults with type 1 diabetes. The main questions it aims to answer are: * Is it safe for participants to start using the insulin pump system at home instead of the hospital? (Measured by the amount of time blood sugar is very low, under 54 mg/dL). * Does this home-based care model help participants keep their blood sugar in a healthy range? * How does this model affect the participants' quality of life, device satisfaction, and overall experience? * Does this model reduce healthcare costs and the need for hospital visits? Participants will: * Complete an online technical training course before the setup. * Receive a home visit from a specialized nurse to configure and start the insulin pump system. * Have their device data monitored remotely every 14 days by the nursing team to manage any health alerts. * Attend scheduled clinical follow-up visits at 1, 3, 6, and 12 months. * Answer surveys about their quality of life, their experience with the healthcare service, and their satisfaction with the new device.

Hybrid Closed Loop Effectiveness Trial in Adults With Type 1 Diabetes

Minoritized individuals with type 1 diabetes (T1D) have approximately 2% higher average A1c levels and twice the rate of hospitalizations, complications, and mortality as their white counterparts. However, the efficacy trials establishing the benefits of hybrid closed loop (HCL) pump therapy in T1D have been in more socially advantaged and predominantly non-Hispanic white patients. Use of this technology by individuals with T1D from underserved communities remains very low. The investigators plan to conduct a randomized effectiveness trial - with broader eligibility criteria (including markedly elevated A1c) and longer follow up than the previous HCL efficacy trials - to evaluate the benefits, safety risks and treatment complications of HCL use in underserved adults with T1D. A comprehensive mixed-methods approach will be implemented to capture information about the user experience. Participants will be randomized (3:1 ratio) to one of three FDA-approved HCL systems or continuous glucose monitoring and multiple daily injection therapy. Subjects will be followed for 9 months to collect data on effectiveness (glucose % time-in-range 70-180 mg/dL and % time \< 70 mg/dL), safety (diabetic ketoacidosis and severe hypoglycemia events) and patient experience using the systems (including benefits and burdens, the impact of life stressors on HCL use, and how the match between HCL system functionality and the individual's needs and expectations impacts on user experience).

Sotagliflozin to Slow Kidney Function Decline in Persons With Type 1 Diabetes and Diabetic Kidney Disease

Powerful new drugs that can prevent or delay end stage kidney disease (ESKD) - so called sodium-glucose cotransporter-2 inhibitors (SGLT2i) - are now available for patients with type 2 diabetes. Whether these drugs have similar effects in patients with type 1 diabetes (T1D) remains unknown because of the few studies in this population, due to concerns about the increase in risk of diabetic ketoacidosis (DKA, a serious, potentially fatal acute complication of diabetes due to the accumulation of substances called ketone bodies) observed with SGLT2i therapy in T1D. One of the few T1D studies conducted to date showed that implementing an enhanced DKA prevention plan can reduce the risk of DKA associated with the SGLT2i sotagliflozin (SOTA) to very low levels. In the present study, a similar DKA prevention program will be used to carry-out a 3-year trial to test the kidney benefit of SOTA in 150 persons with T1D and moderate to advanced DKD. After a 2-month period, during which diabetes care will be standardized and education on monitoring and minimizing DKA implemented, eligible study subjects will be randomly assigned (50/50) to take one tablet of SOTA (200 mg) or a similarly looking inactive tablet (placebo) every day for 3 years followed by 2-months without treatment. Neither the participants nor the study staff will know whether a person was assigned to taking SOTA or the inactive tablet. Kidney function at the end of the study will be compared between the two treatment groups to see whether SOTA prevented kidney function loss in those treated with this drug as compared to those who took the inactive tablet. The DKA prevention program will include participant education, close follow-up with study staff, continuous glucose monitoring, and systematic ketone body self-monitoring with a meter provided by the study. If successful, this study will provide efficacy and safety data that could be used to seek FDA approval of SOTA for the prevention of kidney function decline in patients with T1D and DKD.
