The purpose of this study is to determine a safe,tolerable and efficacious dose of GLU-xx.

The purpose of this study is to evaluate whether an alpha-glucosidase inhibitor, a drug for the suppression of postprandial hyperglycemia, could reduce the recurrence of myocardial infarction in patients with impaired glucose tolerance (IGT) and old myocardial infarction.

The goal of this pilot and feasibility study is to investigate the effects of a short course of metformin therapy on a surrogate marker of cellular senescence and autophagy among adult patients with prediabetes. The overall hypothesis is that metformin will have beneficial effects on longevity and quality of life by inducing autophagy downstream of activating adenosine monophosphate-activated protein kinase (AMPK) and inhibiting mechanistic target of rapamycin (mTOR) through potential effects of reduced inflammation, reduced degeneration of muscle and tendon tissue, antineoplastic effects, reduced obesity and hyperglycemia, preserved cardiovascular functions, and/or the prevention of neurodegeneration (such as age-associated dementia). This pilot study will address the following aim: Demonstrate that metformin therapy will increase cellular autophagy as an inverse correlate of aging as measured by increases in Microtubule-associated protein 1A/1B-light chain 3 (LC3) scores. Hypothesis 1: In addition to beneficial effects on glycemia, body weight, and body composition, metformin therapy exerts beneficial effects on surrogate measures of autophagy and aging. Primary outcome: Increased levels of LC3 in leukocytes.

Prediabetes is defined as an intermediate metabolic state that leads to the development of type 2 diabetes mellitus (DM2) and the prehypertension is a category assigned to identify patients who are at risk of developing hypertension (AH), in both pathologies the abnormalities in the variation of blood pressure (BP) has been related to organ damage, its evaluation is performed by ambulatory blood pressure monitoring (ABPM). Dapagliflozin is a selective and reversible inhibitor of the sodium-glucose co-transporter type 2 (SGLT-2), which reduces renal reabsorption of glucose and promotes the excretion of glucose through the urine, in the way that glucose blood. Another reported effects is the decrease on BP, so it would be interesting to evaluate this effects in patients with prediabetes and prehypertension, as a potential therapy to treat disorders and to prevent progression to DM2 and Hypertension, respectively. The aim of this study is to evaluate the effect of Dapagliflozin on variability of blood pressure in patients with prediabetes and prehypertension without pharmacological treatment. The investigators hypothesis is that the administration of dapagliflozin decreases variability of blood pressure in patients with prediabetes and prehypertension without pharmacological treatment.

The obesity epidemic calls for new therapeutic opportunities to prevent and treat obesity and its comorbidities amongst which are insulin resistance and cardiovascular diseases. Recent evidence suggests that tissue oxygenation plays an important role in cardiometabolic health. Remarkably, individuals residing at high altitude (hypobaric hypoxia) are less prone to develop type 2 diabetes mellitus as compared to individuals living at sea-level (normobaric normoxia). Furthermore, there is evidence to suggest that normobaric hypoxia exposure may improve glucose homeostasis and insulin sensitivity in both rodents and humans. The level of physical activity is an important determinant of insulin sensitivity and glucose homeostasis. It is well established that performing physical activity improves glucose uptake in the short term, and glycemic control in the long term. Interestingly, recent studies have demonstrated that an acute bout of exercise under hypoxic conditions (inhalation of air containing less oxygen) may lead to a more pronounced improvement in plasma glucose concentrations and/or insulin sensitivity as compared to normoxic exercise. However, the effects of repeated hypoxic exercise bouts on glucose profile throughout the day (i.e. 24h continuous glucose monitoring) remain elusive. In the present randomized, placebo-controlled, single-blind, cross-over study study, the investigators will investigate the effects of exercise under mild normobaric hypoxic conditions (FiO2, 15%) for 4 consecutive days (2 x 30-min cycling session at 50% WMAX) on postprandial substrate metabolism and 24h-glucose level in overweight/obese subjects with impaired glucose tolerance. The investigators hypothesize that 4 consecutive days of exposure to mild hypoxia while performing moderate intensity exercise improves glucose homeostasis in overweight and obese individuals with impaired glucose homeostasis.

According to the data from the Di@bet.es study, which is part of the National Diabetes Strategy, the prevalence of type 2 diabetes among Spanish population is 13.8%. Diabetic patients suffer from several short and long term complications, which are related to a significant worsen of quality of life and a substantial increase in death rate. In this sense, it is important to prevent the development of Type 2 diabetes. Therefore, it is of high relevance to identify and to treat prediabetic subjects prior to the development of the disease. Many strategies have been implemented to reverse this situation, such as changes in diet and lifestyle, among others. However, it is hard to achieve changes in lifestyle and despite the use of some drugs in this phase of the disease, the problem continues growing. For this reason, new strategies to combat the development of type 2 diabetes are been investigated, such as the use of probiotic formulations. However, at the moment, few studies evidence the effect of probiotics on glycemic regulation. Therefore, an interesting opportunity arises according to the potential ability of probiotic formulation for the control of prediabetes. Considering this background, the main objective of this research is to assess the effect of a new probiotic formulation on glycemic control, insulin resistance and the composition of the fecal microbiota in prediabetic subjects.

The study is a randomized, cross-over, double blind, controlled trial in which study participants will receive two 4-week interventions with a washout period of 4 weeks between interventions. Study subjects will visit the research facility before and after each intervention period for a test day. In the third intervention week participants are provided with a 3-day controlled diet and glucose responses will be monitored via a continuous glucose monitoring device.

Prediabetes is a term that refers to alterations in glucose homeostasis, including impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or both, involving a higher risk of progression type 2 diabetes mellitus (T2DM). Dapagliflozin is a selective and reversible inhibitor of sodium-glucose type 2 (SGLT-2) co-transporter, which reduces renal glucose reabsorption and promotes the glucose excretion through urine, so that the blood glucose is improved in patients with T2DM. Although this mechanism is independent of insulin, there are evidence of improved secretion and insulin sensitivity, so it is interesting to assess these effects in patients with prediabetes, as potential therapy for treating such disorders and prevent progression to T2DM. The aim of this study is to evaluate the effect of Dapagliflozin on insulin secretion and insulin sensitivity in patients with prediabetes. The investigators hypothesis is that the administration of dapagliflozin improve insulin secretion and insulin sensitivity in patients with prediabetes.

This is a single-centre, 16-week, randomized, double-blind, placebo-controlled, 3-treatment arm pilot study to evaluate the efficacy and safety of BTI320 in the treatment of high risk subjects with pre-diabetes. This is a pilot study aiming to test whether taking a medicine named BTI320 that slows down carbohydrate absorption in the gut, will lower blood sugar. The study aims to recruit 60 individuals in Hong Kong. To take part in the study, subjects must have pre-diabetes, that is, they have blood sugar levels that are above normal but not reaching diabetes range. The medicine BTI320 is currently licensed as a health supplement in Hong Kong and is known alternatively as SUGARDOWN®. The investigators are comparing the effectiveness of BTI320 against a dummy tablet. Both tablets look and taste identical and during the study, subjects will not know which of these tablets they are taking. There is a 4 in 5 chance of receiving active medication and 1 in 5 chance of receiving placebo. Subjects will be followed up closely every 2 to 4 weeks for a period of time up to 22 weeks. The study visits will take between 30 minutes to 3 hours, depending on additional checks that are required on a particular visit including oral glucose tolerance test and meal tolerance test. At visits involving meal tolerance test, subjects will be required to stay for approximately 3 hours. In addition, at Visit 2, Visit 4 and 3 days before Visit 7, a continuous glucose monitoring system device will be installed. Throughout the study period, subjects will return to the study center for check-ups including careful enquiry about whether they have developed any side-effects from taking the medication, physical examination, as well as blood tests.

Insulin resistant subjects and type 2 diabetic patients are characterized by a decreased metabolic flexibility: a reduced capability to switch from fat oxidation in the basal state to carbohydrate oxidation in the insulin-stimulated state. This metabolic inflexibility is an early hallmark in the development of diabetes. Recent evidence suggests that a low carnitine availability may limit acetylcarnitine formation, thereby reducing metabolic flexibility. Thus, when substrate flux in the muscle is high, acetyl-CoA concentrations increase, leading to inhibition of pyruvate dehydrogenase (PDH) and thereby reducing glucose oxidation. The conversion of acetyl-CoA to acetylcarnitine relieves this acetyl-CoA pressure on PDH. To provide more direct insight into the effect of carnitine in preventing metabolic inflexibility and insulin resistance and to further explore the mechanism of action is the focus of this research. Here, we hypothesize that the capacity to form acetylcarnitine may rescue lipid-induced insulin resistance. To this end, insulin resistance will be induced by lipid infusion in healthy volunteers and it will be tested whether carnitine co-infusion can alleviate insulin resistance.
