Metformin

This study is examining whether short-term supplementation with inorganic nitrate, in the form of beetroot juice, can enhance blood vessel health, insulin sensitivity, and exercise capacity in individuals with prediabetes. We will be comparing the responses in individuals who are taking metformin to those who are naive to metformin. The results from this study may help identify non-pharmacological interventions in prediabetes.

he goal of this clinical trial is to compare the mitochondrial redox effects of imeglimin versus metformin monotherapy in adults with newly diagnosed Type 2 diabetes mellitus who are treatment-naive. The main questions it aims to answer are: Does imeglimin improve the fasting plasma pyruvate/lactate ratio (a validated surrogate of mitochondrial NAD⁺/NADH redox balance) to a greater extent than metformin after 12 weeks of treatment? Does imeglimin produce more favorable changes in secondary mitochondrial and glycemic biomarkers - including fasting plasma lactate, fasting plasma pyruvate, HbA1c, HOMA-IR, and lipid profile - compared to metformin? Researchers will compare imeglimin 1000 mg twice daily to metformin up to 1000 mg twice daily to see if imeglimin produces superior improvement in mitochondrial oxidative capacity and cytoplasmic redox balance, reflected by a greater increase in the fasting plasma pyruvate/lactate ratio, without compromising glycemic efficacy or safety. Participants will: Take either imeglimin 1000 mg twice daily or metformin (titrated up to 1000 mg twice daily) orally for 12 weeks, as assigned by randomization Attend clinic visits at baseline (Week 0) and at Week 12 for fasting blood sample collection, including strict bedside deproteinization of pyruvate samples using ice-cold perchloric acid to ensure analytical accuracy Undergo measurement of fasting plasma pyruvate/lactate ratio, HbA1c, HOMA-IR, fasting glucose, fasting insulin, fasting plasma lactate, fasting plasma pyruvate, and full lipid profile at both visits Be monitored for adverse events and safety parameters, including renal function (eGFR), throughout the study period

This research will help us to learn if the medicine called metformin reduces the risk of death, heart attacks, and/or strokes in Veterans who have pre-diabetes and heart or blood vessel problems.

The study team hypothesize that non-diabetic patients with Myotonic dystrophy type I (DM1) will improve their symptoms, especially their motor deficit which is the main feature of the disease, because of the splicing defect correction by metformin. The primary objective of the study is to evaluate the efficacy of metformin vs placebo, on the improvement of muscle function in patients with DM1 compared to its placebo. As the secondary objectives, the study aims: * To evaluate the safety of metformin on patient with DM1. * To evaluate the efficacy of metformin vs placebo on: 1. The hand-grip strength; 2. The thumb-index pinch strength; 3. The locomotor function; 4. The respiratory function; 5. The cardiac function; 6. The quality of life; 7. The daily and social activity.

This study looks at patients admitted to intensive care for drug poisoning involving metformin, a common diabetes medication. Researchers will compare two groups: patients who overdosed on metformin alone and those who took both metformin and dapagliflozin, another diabetes drug. The goal is to find clinical or laboratory signs that could help doctors quickly recognize a dapagliflozin overdose in this context, which could improve treatment and patient outcomes.

About 75% of CNS malignant tumors are classified as gliomas and the IDH-wildtype glioblastoma (GBM) represents the most aggressive form among CNS malignancies. This is a nationwide single-center phase II drug clinical trial with an approximate duration of 32 months. The clinical trial will be single-arm to evaluate the biological activity and effects of metformin in combination with TMZ in patients with GBM.

The objective of this research is to assess the efficacy of oral metformin in mitigating the aging process in middle-aged and elderly males, to pinpoint sensitive indicators of human senescence, and to offer innovative frameworks and scientific insights for pharmaceutical interventions in aging.

This study is a controlled trial of metformin in children with fragile X syndrome(FXS). The age of FXS children range from 2 to 16 years old. Participants will be randomized in a double-blind design to either drug or placebo for 6-month period. The primary objectives are to assess metformin in treatment of behavior problems, cognitive and language with fragile X syndrome.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility and is characterized by ovulatory dysfunction, increased androgens, and polycystic ovaries. The goal of this randomized control study is to compare the efficacy between acupuncture and metformin both with intensive lifestyle intervention for overweight /obese PCOS patients in weight and pregnancy rates improvement.

To evaluate the efficacy and safety of metformin pretreatment on reproductive outcomes in infertile women with prediabetes.

In this study, the investigators will include PCOS patients who meet the trial criteria, introduce participants to the content of this study, and invite participants to participate. The immune function of peripheral blood samples of PCOS patients was detected by flow cytometry. Participants were further treated with metformin for 6 months and followed up after the intervention. The objective of this study was to investigate immune markers related to the efficacy of metformin in PCOS patients and to predict the efficacy of metformin in PCOS patients using immune function.

This study is a randomized trial that evaluates the effect of metformin addition or not to standard care on the duration of diabetes remission after bariatric surgery.

This multicenter, randomized, open-label, controlled study will assess the efficacy of the SGLT2 inhibitor tofogliflozin on Urine Albumin-to-Creatinine Ratio (UACR) compared to metformin in patients with type 2 diabetes with chronic kidney disease (CKD).
