Diabetes Type 1 clinical trials at UCSD

The purpose of the CLEAR study is to determine the effect on counterregulatory responses (CRR) of intervening (by attempting to strictly avoid hypoglycemia) to improve awareness of hypoglycemic symptoms among adults with type 1 diabetes (T1D) who have impaired awareness of hypoglycemia (IAH). IAH affects 20-25% of adults with T1D, and rises with increasing duration of T1D.

This study will examine the effects a Glucagon Receptor Antagonist (GRA), has on Insulin Sensitivity, Cardiovascular risks (CVD), and Ketone body formation in participants with Type 1 diabetes. The participants will complete blood tests, tests to measure energy expenditure, CVD risks, and insulin resistance. These tests will be performed prior to start of treatment and again after 12-weeks of treatment with the GRA (called REMD-477).

This trial is designed to evaluate the effect of glucagon receptor antagonism by volagidemab (once weekly) on glucose recovery from hypoglycemia after treatment with glucagon in adults with type 1 diabetes. After informed consent, Screening procedures to establish subject eligibility will be performed within a period of 28 days. Approximately 24 subjects with type 1 diabetes mellitus (T1DM) on stable doses of insulin will be enrolled. After enrollment, subjects will undergo a baseline Hypoglycemia Recovery Procedure (with glucagon rescue). Subjects will then receive volagidemab subcutaneously (SC) once weekly for 6 weeks. At the end of the treatment phase, subjects will undergo a second Hypoglycemia Recovery Procedure. Subjects will be followed for 6 weeks after the last volagidemab dose with a final End-of-Study (EOS) visit during Week 12. The primary outcome will be the change in time to glucagon treatment success at Week 6 versus baseline.

This is a single-site study using wearable sensor technology (CGM and smartwatch) to better explain low blood sugars in patients living with type 1 diabetes. Up to 20 participants with T1D will wear a continuous glucose monitor (CGM) and a smartwatch to collect information about hypoglycemia (low blood sugar), heart rate variability (HRV), and sleep for 4 weeks. The main goal is to create a hypoglycemia risk score using wearable sensor metrics that can be easily applied to all patients with T1D to identify those at greater risk of hypoglycemia.
