Diabetes clinical trials at UCSD

The purpose of the trial is to assess the efficacy and safety of tirzepatide to dulaglutide in participants with type 2 diabetes and increased cardiovascular risk.

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.

The study is a single-center, randomized, participant- and observer-masked, human-subjects, post-market clinical pilot study to investigate the use of ultrasound-guided percutaneous cryoneurolysis to treat diabetic neuropathy of the foot. A prolonged nerve block may be provided by freezing the nerve using a technique called "cryoneurolysis". With cryoneurolysis and ultrasound machines, a small needle-like "probe" may be placed through anesthetized skin and guided to the target nerve to allow freezing. The procedure takes about 6 minutes for each nerve, involves little discomfort, has no systemic side effects, and cannot be misused or become addictive. Participants will be randomly allocated to one of two possible treatments groups: cryoneurolysis (experimental) or sham (control). The primary outcome measure is the change in pain on the neuropathic pain scale from baseline 1 month following the procedure.

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 multicenter, randomized, placebo-controlled, 2-part study to evaluate the safety and efficacy of AT-001 in adult patients (N=675) with Diabetic Cardiomyopathy at high risk of progression to overt heart failure.

This study will examine the effects THC has on Glucose Metabolism and Endothelial Functioning in participants with Type 2 Diabetes. The participants will complete blood tests and tests to measure energy expenditure, CVD risks, and glucose metabolism. These tests will be performed prior to start of treatment and again after 2-weeks of treatment with the THC or placebo.

This is a clinical trial to assess how time-restricted eating (TRE) may improve kidney health and filtration patients with type 2 diabetes and increased protein content in their urine. All participants will be participating in TRE in which they follow a consistent 8-10 hour eating window everyday.

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.

The study will collect a cross-sectional dataset of 4000 people across the US from diverse racial/ethnic groups who are either 1) healthy, or 2) belong in one of the three stages of diabetes severity (pre-diabetes/diet controlled, oral medication and/or non-insulin-injectable medication controlled, or insulin dependent), forming a total of four groups of patients. Clinical data (social determinants of health surveys, continuous glucose monitoring data, biomarkers, genetic data, retinal imaging, cognitive testing, etc.) will be collected. The purpose of this project is data generation to allow future creation of artificial intelligence/machine learning (AI/ML) algorithms aimed at defining disease trajectories and underlying genetic links in different racial/ethnic cohorts. A smaller subgroup of participants will be invited to come for a follow-up visit in year 4 of the project (longitudinal arm of the study). Data will be placed in an open-source repository and samples will be sent to the study sample repository and used for future research.
