Diabetes clinical trials at UC Davis

8 research studies open to eligible people

Showing trials for
  • A Study of Experimental Treatment With Micropulse for Diabetic Macular Edema (build-up of fluid in the eye)

    “This study will test the effect of using the subthreshold micropulse diode laser (SML).”

    open to eligible people ages 18 years and up

    Diabetic retinopathy is one of the most common complications of diabetes and diabetic macular edema (DME) is one of the most common causes of vision loss in diabetes. The purpose of this study is to determine if early intervention with micropulse laser treatment in eyes with good visual acuity (20/32 or better) will improve or stabilize vision loss due to the complications of diabetic macular edema.

  • A Study of the Effect of Orange Juice or Sugar-Sweetened Beverages on Risk Factors for Type 2 Diabetes and Cardiovascular Disease

    “In this study, the study team will provide meals and either sugar-sweetened beverages or orange juice.”

    open to eligible people ages 18-50

    The objectives of this proposal are to address the gaps in knowledge regarding the metabolic effects of consuming orange juice, the most frequently consumed fruit juice in this country, compared to sugar-sweetened beverage.

  • A Study of Time-Restricted Eating on Heart Health & Metabolism

    open to eligible people ages 21-70

    Time-restricted eating (TRE) is a dietary manipulation that involves restricting food intake to 6-12 h/day with no energy intake the rest of the day. In rodents, TRE improves metabolic function without caloric restriction, potentially by activating nutrient sensing mechanisms and effects on circadian oscillations. However, an understanding of the effect of TRE on cardiometabolic health in people is not clear and few studies have evaluated this issue. Accordingly, the investigators propose to conduct a randomized controlled trial in people with obesity and prediabetes to determine the effect of 9 h TRE for 12 weeks, without a change in body weight, on key metabolic outcomes that are risk factors for cardiovascular disease (CVD): 1) multi-organ insulin sensitivity; 2) 24 h metabolic homeostasis and diurnal rhythm; and 3) adipose tissue and skeletal muscle biology. The proposed studies will elucidate the cardiometabolic implications of TRE in people with obesity and prediabetes.

  • CGM - A Study of Glucose Monitoring in Kidney Transplant Recipients

    “Volunteer for research and contribute to discoveries that may improve health care for you, your family, and your community!”

    open to eligible people ages 18 years and up

    The investigators want to study the impact CGM (continuous glucose monitoring) has on patients glycemic control as determined by time in range (TIR 70-180 mg/dL) in the Diabetic Kidney Transplant population.

  • Clinical Trial of Stem Cell Use in Vision Loss

    “We hope to learn more about the safety and feasibility of using your own (autologous) stem cells extracted from your bone marrow.”

    open to eligible people ages 18-100

    This pilot study is to determine whether it would be safe and feasible to inject CD34+ stem cells from bone marrow into the eye as treatment for patients who are irreversibly blind from various retinal conditions.

  • Dementia & Diabetes Prevention Program (DDPP)

    open to eligible people ages 60 years and up

    This is a multicenter, randomized 2-arm clinical trial of two lifestyle interventions varying in intensity and format, in 400 older African American and non-Hispanic whites at increased risk of cognitive decline and dementia in the East San Francisco Bay Area. The trial will include two lifestyle interventions that differ in intensity and format: 1. Aerobic Exercise (AEx) Intervention that involves aerobic activities with in-class walking workouts and tutorials and carried out at the East Oakland Sports Center (EOSC) and Tice Creek Fitness Center (TICE). 2. Dietary counseling to support adherence to the Mediterranean-Diet Approaches to Stop Hypertension (DASH) Intervention for Neurodegenerative Delay (MIND) diet to encourage increased consumption of berries, green leafy and other vegetables, whole grains, nuts, fish, poultry, beans and olive oil, and to reduce consumption of fried/fast foods, red meat, whole fat cheese, sweets, butter and trans-fat margarines.

  • Dietary Intervention to Improve Kidney Transplant Outcomes

    open to eligible people ages 18 years and up

    Randomized controlled trial of a curriculum intervention teaching patients to eat a whole-food plant-based dietary pattern versus standard of care in kidney transplant recipients within the first few months of transplant

  • Exercise and Energy Production in Chronic Kidney Disease Study

    “Adults ages 30-80 with Chronic Kidney Disease can participate in a new exercise study to help improve muscle function. See if you qualify!”

    open to eligible people ages 30-75

    Skeletal muscle dysfunction (sarcopenia) is an under-recognized target organ complication of CKD with substantial adverse clinical consequences of disability, hospitalization, and death. Sarcopenia in this proposal is defined by impaired metabolism and physical function associated with decreased skeletal muscle mass or function. Skeletal muscle tissue relies on mitochondria to efficiently utilize oxygen to generate ATP. Impaired mitochondrial energetics is a central mechanism of sarcopenia in CKD. The investigators propose a series of studies designed to shed light on the pathophysiology of sarcopenia in persons with CKD not treated with dialysis. Investigators will conduct a randomized-controlled intervention trial of combined resistance training and aerobic exercise vs. health education to assess changes in skeletal muscle mitochondrial function, metabolism and physical function. Investigators hypothesize that exercise improves mitochondrial function and physical function in persons with CKD. If successful, these experiments will identify novel pathophysiologic mechanisms for CKD-associated sarcopenia. The proposed study will provide useful insight into benefits associated with exercise among patients with CKD and investigate mechanisms associated with improved metabolism, muscle function and physical function in population.
