Type 2 Diabetes Clinical Trials

The goal of this research study is to evaluate the pathophysiologic mechanisms by which genetic variation impacts response to an FDA-approved medication commonly used to treat type 2 diabetes called oral semaglutide (Rybelsus) and to characterize the physiological response to a mixed meal tolerance test (MMTT) before and after a 14-day treatment with oral semaglutide. The investigators will do this by measuring factors in the blood, such as sugars, fats, metabolites, and proteins, after eating a standardized breakfast meal at the first visit and after taking 14 doses of oral semaglutide over two weeks before the second study visit. The food (mixed meal breakfast) we will be studying is specially prepared to contain a set amount of protein, carbohydrates, and fat. The investigators hypothesize that understanding how the acute biochemical response to oral semaglutide differs by genetic variation will generate insight into drug mechanisms and type 2 diabetes pathophysiology.

The proposed 6-month pilot Sequential Multiple Assignment Randomize Trial (SMART) has two aims. The first and primary aim is to determine the feasibility of conducting a full-scale SMART to compare weight-focused (i.e., weight loss) and weight-neutral (i.e., weight loss is not an explicit goal) adaptive biobehavioral interventions for improving cardiometabolic health in Black adults with overweight or obesity (BMI ≥27 kg/m2) plus at least one weight-related cardiometabolic condition (high blood pressure, prediabetes or diabetes, and/or high cholesterol). Biobehavioral interventions are treatment strategies that combine lifestyle-based behavioral interventions such as eating a healthy diet and exercise with medications. In this study, participants will be randomly assigned to receive either weight-focused or weight-neutral health coaching for 7 weeks. At week 8, participants will be identified as either "responders" or "nonresponders" to the initial interventions. The threshold for response in the weight-focused condition is greater than or equal to 3% weight loss. The threshold for response in the weight-neutral condition is engaging in greater than or equal to 150 minutes of moderate physical activity for the 7 days prior to the week 8 study visit. Responders to the initial interventions will continue with health coaching on a biweekly basis for weeks 9-26 of the intervention. Nonresponders will be re-randomized to either intensify the lifestyle-based intervention by receiving a membership to the YMCA and enrolling in group fitness classes or augmenting the health coaching with enhanced medical management in partnership with their established primary care provider. The second aim is to use clinical data from the pilot SMART to estimate treatment effects and the between-person variability in these effects. Because this is a pilot study, these estimates will not be used to make comparisons or draw conclusions on the comparative effectiveness of intervention conditions. Rather, these data will be used to generate preliminary effect sizes that can be used to estimate the sample size required for a full-scale trial. Clinical trial feasibility data will be collected on an ongoing basis throughout the study and clinical data will be collected prior to initiating the intervention (baseline) and at week 8 (response visit) and week 26 (post-intervention visit).

The overall goal of this study is to examine the efficacy of the video-based Diabetes Self-Management Education and Support (DSMES) (hereafter VIDEO), or the video-based DSMES+community health worker (CHW) intervention (hereafter VIDEO+CHW), compared with a wait-list control group (hereafter CONTROL) to improve glycemic control among Chinese immigrants with uncontrolled Type 2 diabetes in NYC.

It is not known whether a new diabetes drug, semaglutide, is an effective treatment for type 2 diabetes for persons with spinal cord injury (SCI), a population at higher risk for this condition. Therefore, this study looks at the effect of semaglutide on glucose levels in the body and other information about type 2 diabetes and obesity. Read Less

The disparate burden of Type 2 Diabetes (T2D) faced by Black individuals makes attention to preventing or delaying the development of T2D and its associated cardiovascular (CV) complications, essential. Similar to differences in cardiovascular disease (CVD) rates across racial and ethnic groups of older people, there are differences in engagement in physical activity (PA), a significant contributor to CVD. Black adults are less likely to engage in physical activity PA than their non-Hispanic White peers, with 26.7% of Black Minnesotans reporting that they did not engage any leisure-time PA in the past month, compared to 19.6% of non-Hispanic White Minnesotans. Notably, recent research has demonstrated that high amounts SB (i.e., sitting or lying with low levels of energy expenditure) also have significant detrimental effects on health, beyond those of physical inactivity. Experimental data from lab-based studies demonstrate that breaking up prolonged SB can rapidly improve markers of cardiometabolic risk (e.g., glucose and endothelial function) but the majority of these studies have focused on young, healthy, White adults. Given the significant inequities and health disparities faced by Black individuals and the lack of adequate representation of Black older adults in studies examining SB in individuals with T2D, understanding psychosocial and societal contributors to and consequences of SB experienced by this population is an essential first step toward developing relevant interventions targeting SB, and ultimately, CV health.

The goal is to develop a deeper understanding of individuals' experiences of sedentary behavior (SB) and collaborate to design strategies to reduce SB. Using the Center for Chronic Disease Reduction and Equity Promotion Across Minnesota (C2DREAM) conceptual model, social-ecological framework, and COM-B model, the study will seek to understand the relationship between SB and individual, relationship, community, and societal factors. The study will also examine the context of SB and strategies that participants have used and could or would consider using to break up the time they spend sitting. Read Less

The purpose of this clinical trial is to test the safety and feasibility of using an Automated Insulin Device (AID) in people with Type 2 Diabetes under basal insulin injections to achieve safe and fast basal insulin titration. Participants will be randomized to either the control group or the experimental group. If in the experimental group, the participant will use an insulin pump with Control-IQ Technology (Tandem Diabetes Care) for ten days. Researchers will compare the glycemic control of the experimental group to the control group. Read Less

The goal of this IDEAL project is to examine the effectiveness and implementation process of the video-based Diabetes Self-Management Education and Support (DSMES) + community health worker (CHW) (hereafter: "IDEAL") intervention compared with a wait-list control group (hereafter: "CONTROL") to improve glycemic control among Chinese immigrants with Type 2 diabetes (T2D) in New York City (NYC). Participants will be randomized with equal allocation to one of the 2 groups. The IDEAL group will receive 1 DSMES brief video/week for 24 weeks delivered via text message. The CHW will assess participants' SDOH barriers to T2D care and link them to available resources in the community. The CONTROL group will continue to receive their usual care and at the end of the study, they will receive DSMES videos. Read Less
