NCT01105858
Background: \- Family and twin studies have suggested that genetic factors influence approximately 50 percent of a person's susceptibility to type 2 diabetes. Recently, some of the genes involved in the development of type 2 diabetes have been identified, in large part by genome-wide association studies. Certain risk factors for type 2 diabetes, such as obesity and insulin resistance, are highly inheritable, as are diabetic complications such as diabetes-related eye and kidney disorders. However, few genes associated or linked with diabetes risk factors or complications have been conclusively identified, and more research is needed to study specific genetic factors associated with these aspects of diabetes. Objectives: \- To identify and characterize genetic variants associated with type 2 diabetes, its risk factors, and its complications. Eligibility: \- Individuals at least 18 years of age who are not pregnant or nursing mothers at the start of the study. Design: * All participants will provide information about family history, ethnicity and ethnic background, occupation, behavioral risk factors, and other data as requested by the researchers. * In addition to a general health history, participants will provide specific information about diabetes history, with particular emphasis on date of diagnosis, symptoms, initiation of insulin therapy, complications, and current medications. * Testing procedures will be different for individuals with and without diabetes. Those without diabetes will have an oral glucose tolerance test, while those with diabetes will be examined for diabetic complications. * Other tests during the study will include the following: * Physical examination with measurements of height and weight, waist circumference, blood pressure, and other tests for individuals who have been diagnosed with diabetes * Glucose tolerance test for those who have not been classified as having diabetes * Retinal photographs * Electrocardiograms * Hepatic Ultrasound * Blood and urine tests * Depending on the results of the examination and laboratory findings, participants may be asked to return to the clinic for supplemental interviews, physical examinations, or blood tests, or to arrange referrals for medical evaluation and treatment. * Participants who have diabetes will be asked to return for yearly follow-up visits. Participants who do not have diabetes at the initial examination will be asked to return for follow-up visits every 2 years.
NCT06066528
This study is open to adults who are at least 18 years old and have a body mass index of 27 kg/m² or more. People can take part if they have type 2 diabetes and if they are currently being treated only with diet and exercise or with specific diabetes medications. Only people who have previously not managed to lose weight by changing their diet can participate. The purpose of this study is to find out whether a medicine called survodutide (BI 456906) helps people living with overweight or obesity who also have diabetes to lose weight. Participants are divided into 3 groups by chance, like drawing names from a hat. 2 groups get different doses of survodutide and 1 group gets placebo. Placebo looks like survodutide but does not contain any medicine. Every participant has a 2 in 3 chance of getting survodutide. Participants inject survodutide or placebo under their skin once a week for about one and a half years. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly. Participants are in the study for about 1 year and 7 months. During this time, it is planned that participants visit the study site up to 14 times and receive 6 phone calls by the site staff. The doctors check participants' health and take note of any unwanted effects. The study staff also regularly measure participants' body weight. The results are compared between the groups to see whether the treatment works.
