A Study of GNTI-122 in Adults Recently Diagnosed With T1D
This is a 78-week single arm, multi-center, Phase 1 study to evaluate the safety, tolerability, cellular kinetics, and biomarker changes in C-peptide over time of GNTI-122, an investigational cell therapy manufactured from a participant's own blood cells in adult participants with recently diagnosed T1D. After assessment of eligibility, participants who qualify for the study will be enrolled sequentially in 1 of 3 cohorts. Cohort 1 participants (n=3) receive a low dose of GNTI-122 . Cohort 2 participants (n=3) receive a high dose of GNTI-122. Cohort 3 participants (n=10) receive a high dose of GNTI-122 in combination with rapamycin. Participants are followed for 78 weeks after the administration of GNTI-122 during which safety and efficacy assessments are made, including vital signs, ECG, physical exam, clinical labs, and monitoring of adverse events and concomitant medications. Disease markers (e.g., MMTT-stimulated C-peptide, HbA1c) and pharmacodynamic activity (e.g., lymphocyte subsets and phenotypes, effector T cell responses to islet antigens ex vivo, T1D autoantibodies) will be monitored serially throughout the study. The study will include sentinel dosing and a Safety Review Committee to ensure participant safety. Visit https://www.polarisstudy.com to learn more!

Safety, Tolerability, and Efficacy of Immunomodulation With A Monoclonal Antibody Against CD40L in Combination With Transplanted Islet Cells in Adults With Brittle Type 1 Diabetes Mellitus (T1D)
Tegoprubart (AT-1501) is a monoclonal antibody. Antibodies are Y-shaped proteins that are produced naturally by the subject's immune system to attack and fight foreign substances that cause illness. Monoclonal antibodies are man-made proteins manufactured to serve as substitute antibodies to fight diseases. Monoclonal antibodies can restore, enhance, or mimic (copy) the immune system's attack process; they can also tone down the immune system. Tegoprubart (AT-1501) is thought to work by dampening down the immune system so that it will be less likely to attack the transplanted cells. For other types of transplants, like kidney, a drug called a calcineurin inhibitor is usually used to prevent rejection. That class of drugs can be toxic to islet cells. Tegoprubart (AT-1501) is an experimental agent that is anticipated to prevent rejection without harming the islet cells.

Clinical Study: Analysis of Glycemic Control and Satisfaction With a Connected Smart Cap in Patients With Type 1 Diabetes Mellitus
This clinical study evaluates the impact of the Cap INSULCLOCK device on glycemic control, treatment adherence, and patient satisfaction in adults with type 1 diabetes mellitus (T1DM). Despite advances in pharmacology and technology, a significant proportion of individuals with T1DM fail to achieve recommended glycemic targets, partly due to the complexity of insulin therapy and suboptimal adherence. Cap INSULCLOCK is a device that attaches to insulin pens, automatically recording injections and integrating data on glucose levels, insulin administration, food intake, and physical activity, with real-time Bluetooth transmission. Its use may enhance adherence and optimize metabolic control. This study is a randomized, low-intervention clinical trial conducted at a single center, enrolling 42 patients, who will be randomized into two groups: one using the activated device and a control group using the device in a blinded mode. The primary objective is to assess differences in time above range (TAR \>180 mg/dL) over the last 14 days of continuous glucose monitoring (CGM). Secondary objectives include evaluating HbA1c levels, time in range (TIR), frequency of hypoglycemic episodes, and patient satisfaction. Data will be analyzed using advanced statistical methods, and the intervention is expected to improve adherence, reduce glycemic variability, and enhance quality of life in individuals with T1DM

Home Video-based Telemedicine to Reduce Hypoglycemia Fear in Parents of Young Children
Investigators developed REDCHiP (Reducing Emotional Distress for Childhood Hypoglycemia in Parents), an innovative video-based telemedicine intervention. In the pilot work, investigators found preliminary efficacy for REDCHiP in reducing parental FH, parenting stress, and children's HbA1c. The objective of this clinical trial is to conduct a randomized clinical trial (RCT) comparing REDCHiP to a relevant attention control intervention (ATTN) in families of young children, thereby continuing to establish its efficacy. The proposed R01 aims are: 1) To evaluate whether parents who receive REDCHiP report reductions in FH and parenting stress at post-treatment compared to parents who receive the ATTN; 2) To evaluate whether children of parents who receive REDCHiP have a lower HbA1c and less glycemic variability at post-treatment compared to children of parents who receive ATTN; 3) To examine whether families who receive REDCHiP maintain reductions in FH, parenting stress, and child HbA1c at a 3-month followup compared to families who receive ATTN.
