Mitochondrial Redox Modulation in Newly Diagnosed Type 2 Diabetes: A Randomized Controlled Trial Comparing Imeglimin vs. Metformin Monotherapy
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

Safety and Feasibility of Metformin for Sepsis Induced AKI
Acute kidney injury (AKI) is an independent risk factor for death that affects 10-15% of hospitalized patients and more than 50% of patients admitted to the intensive care unit. Sepsis is the most frequent cause of AKI, affecting 48 million people worldwide every year, and accounting for approximately 11 million of annual global deaths. Despite these figures, there are no known therapies to prevent or reverse septic AKI; hence this study aims to establish the safety and feasibility of the implementation of metformin in the treatment of AKI in patients with sepsis. This study is the first critical step to inform the design of a future, full-scale efficacy randomized clinical trial.

Short-Term Metformin Use in Young, Healthy Adults: Impacts on Exercise Capacity
Metformin is the most prescribed blood sugar (glucose)-lowering medication for patients diagnosed with type 2 diabetes mellitus (T2DM). Metformin stimulates glucose uptake in skeletal muscle similar to the effects of exercise, though, some studies report that metformin may decrease exercise capacity. The main question this study looks to answer is: • Does metformin alter exercise capacity? Participants will: * Complete 5 exercise tests on a stationary bike. * Undergo a body composition test. * Take metformin and placebo. * Complete food and symptom logs. The researchers hypothesize that: • Metformin will reduce aerobic capacity.

Evaluation of the Efficacy and Safety of Metformin in the Myotonic Dystrophy Type 1 (Steinert's Disease)
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.

Clinical and Biological Signs of Dapagliflozin Overdose in ICU Patients With Metformin Poisoning
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.

Metabolic Responses of Metformin and Genetic Polymorphisms of SLC22A1 Gene in PCOS
The aim of this study is to see the associations of metabolic responses of metformin with single nucleotide polymorphisms (SNPs) (rs628031 and rs2282143) of solute carrier family 22 member 1 (SLC22A1) gene in women with polycystic ovary syndrome (PCOS). This prospective clinical study will be conducted in the department of Endocrinology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from February 2023 to September 2024 over a period of two years. A total of at least 100 women with PCOS (18 - 35 years) diagnosed based on International Evidence-based Guideline for PCOS 2018, will be included consecutively by convenient sampling. After taking informed written consent, relevant clinical history will be taken and physical examinations will be done at baseline. Following a run in phase of three weeks, patients will visit thrice after 1, 12 \& 24 weeks of metformin maintenance therapy with a window period of 14 days both ways. Blood samples will be collected in fasting state at baseline and after 24 weeks of treatment to measure glycemic status, lipid profile, fasting insulin, c-peptide and detection of SLC22A1 gene (rs628031 and rs2282143) polymorphisms. Glucose will be measured by glucose oxidase method, lipids by glycerol phosphate dehydrogenase peroxidase method, insulin by chemiluminescent microparticle immunoassay, c-peptide by enzyme-linked immunosorbent assay (ELISA) and genetic analysis of rs628031 and rs2282143 by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

Chemoradiotherapy With or Without Metformin in Locally Advanced Cervical Cancer
This is a prospective, single-center, phase II, randomized, window-of-opportunity trial initiated by researchers. The research hypothesis is that metformin can improve the level of hypoxia in locally advanced cervical cancer and further improve progression-free survival. The study aims to compare the improvement of tumor hypoxia with synchronous chemoradiotherapy with or without metformin, using CA-IX PET/CT and radiation positioning spectral CT to evaluate tumor hypoxia, screening hypoxic patients for inclusion in the study, and comparing the effects of synchronous chemoradiotherapy with or without metformin on the degree of hypoxia and progression-free survival in the two groups of patients.
