Diabetes Clinical Trials in Ann Arbor, MI

This research is being done because people with diabetes have reduced healing capacity and prone to develop infections of foot wounds. This can be problematic because wounds that become infected may result in amputation and more severe complications. New evidence suggests that a better understanding of the microbiome of wounds (e.g., bacterial presence) may provide information about wound healing and provide an earlier opportunity to identify an individual who may be prone to develop diabetic foot infection in their wound. Therefore, the purpose of this study is to evaluate the role of the microbiome of the diabetic foot ulcer in development of infection and wound healing. Once the role of the microbiome is confirmed, progress towards the prevention and treatment of diabetic foot ulcers and complications may be possible. Read Less

The goal of this open-label, non-randomized clinical trial is to determine what effects, if any, an FDA-approved drug class known as SGLT2 inhibitors (Canagliflozin or INVOKANA) has any protective effects on kidney function in Type 2 diabetes. We are looking for participants 18-80 years of age, who have had a clinical diagnosis of Type 2 diabetes for ≥ 3 years. Participants will be asked to sign a consent and complete a screening visit prior to study entry including the following procedures for this study: Consent and Screening: Laboratory tests to determine baseline health Ultrasound to measure kidney size and ensure presence of 2 functioning kidneys Month 0: Study entry kidney MRI (day 0) Study entry kidney biopsy (within 30 days of MRI) Study entry visit for dispensing 100 mg/daily Canagliflozin medication 3 month supply Month 3: Study visit to dispense remaining 3 months of 100 mg/daily Canagliflozin medication Review of systems Month 6: Follow-up kidney MRI Follow-up kidney biopsy Study participants will also be requested to provide blood and urine samples for biobanking purposes. They will also be provided the opportunity to provide a stool sample at two time points, as well as the option to participate in a related study collecting samples to create induced Pluripotent Stem Cells (iPSCs). Participants will be compensated for their time and loss of work time, additionally, a nominal additional compensation for optional stool and iPSC samples. Read Less

The goal of this study is to improve the therapeutic management of diabetic foot ulcers (DFU). The main questions to answer are if a program of non-weight bearing exercise helps the DFU heal faster than standard wound care. This randomized clinical trial will determine how blood flow to the ulcer and whole body metabolism may be improved with exercise. Participants will be randomized to either exercise + standard wound care or standard wound care alone and undergo testing for leg blood flow, fitness and measures of metabolism through blood draws. The intervention period is 6-weeks. Eligible participants must have an existing foot ulcer uncomplicated by infection and be medically cleared to exercise. Read Less

The purpose of this study is to evaluate the safety and effectiveness of the Hybrid Closed Loop system (HCL) in adult and pediatric patients with type 1 diabetes in the home setting. A diverse population of patients with type 1 diabetes will be studied. The study population will have a large range for duration of diabetes and glycemic control, as measured by glycosylated hemoglobin (A1C). They will be enrolled in the study regardless of their prior diabetes regimen, including using Multiple Daily Injections (MDI), Continuous Subcutaneous Insulin Infusion (CSII) or Sensor-Augmented Pump therapy (SAP) Read Less

This single site investigator-initiated prospective observational study will enroll up to 150 participants 13-26 years of age with Type 1 diabetes (T1D) and utilize ecological momentary assessment methods (EMA) to examine associations between different diabetes psychological domains (distress, anxiety, and depression) in real-time on self-efficacy, self-management behaviors, and glycemic outcomes.

This study is a platform study designed to efficiently test multiple biomarkers to identify diabetic foot ulcers (DFUs) with a higher potential for healing versus not healing that ultimately could be applied at the point of care to drive personalized management decisions, and to better inform clinical trials of wound healing interventions Read Less

The Michigan Men's Diabetes Project 2 (MenD 2) is an 18-month pilot randomized clinical trial. We are looking to recruit 60 Black men with type 2 diabetes (need to have diagnosis for at least 6 months) that are over the age of 21. Interested participants need to be under the care of a physician for their diabetes, have access to reliable transportation for study activities, and be willing to participate in 4 health assessments where they will get their A1C, blood pressure, height, and weight measured and they will complete a survey. All participants will receive 10 hours of diabetes self-management education with a Certified Diabetes Care and Education Specialist. Participants randomized to the intervention arm will also be offered 6 months of monthly diabetes self-management support (DSMS) sessions with trained Peer Leaders who are also Black men with type 2 diabetes. After the 6 months of support, this group will transition into 6 months of ongoing support where they can continue DSMS and/or other diabetes related initiatives that are important to the group and chosen by the group. Due to the COVID-19 pandemic, DSME and DSMS sessions will likely be held via Zoom, ongoing support sessions have potential to be in person. The 4 health assessments will take place at baseline, 3-months, 9-months, and 15-months. Read Less

A mobile health program "HypoPals", which incorporates data from continuous glucose monitoring systems (CGMs) and sends personalized text messages to help people sharpen their low blood sugar symptom detection skills, and help people consider how they think of low blood sugar, was devised. The goal of the current study is to make sure that HypoPals runs smoothly, users find the intervention useful, and the way the researchers conduct the final study will be correct (i.e., there is a need for 'pilot testing' the developed technology and research methods). All participants will receive basic hypoglycemia education text messages, and then be randomized to one of the four experimental conditions: Hypoglycemia Symptom Detection Training, Education Plus, both Symptom Detection Training and Education Plus, and usual care. Participants may receive additional interventional text messages based on the experimental condition participants are assigned to. The study may terminate after collecting sufficient data to evaluate the primary outcome (i.e., determining the number of participants recruited to reach 20 participants who complete the intervention).

This is a multi-center observational cohort study of patients with diabetic foot ulcers (DFU) to develop and validate potential tissue-based biomarkers that predict complete wound healing. Eligible and consented participants will begin standard of care treatment after collection of tissue specimens from the wound's edge. An additional tissue specimen is collected at 4 weeks if clinically indicated. Tissues will be tested for c-myc and phosphorylated glucocorticoid receptor (p-GR) levels using validated protocols at a central laboratory. Participants will be followed weekly for up to 12 weeks or until complete wound healing (whichever occurs first). One final assessment 2 weeks after complete wound healing will occur to confirm healing. Read Less
