O estudo clínico NCT05182970 (MIMET) procura avaliar a prevenção para Pré-diabetes, Infarto Agudo do Miocárdio, Infarto do miocárdio sem elevação do segmento ST, Infarto do Miocárdio com Supradesnivelamento de ST. Este é um ensaio intervencionista de Fase III. Seu status atual é: recrutando. O estudo começou em 2 de dezembro de 2021 e pretende incluir 5.160 participantes. Coordenado por o Instituto Karolinska e deve ser concluído em 1 de maio de 2026. Essas informações foram atualizadas no ClinicalTrials.gov em 2 de abril de 2024.
Resumo
Prediabetes is associated to an increased risk of cardiovascular disease and mortality. Although metformin can delay progression to diabetes there is a lack of RCTs evaluating the effect of metformin on cardiovascular outcomes. MIMET aims to investigate if addition of metformin to standard care has effects on the occurrence of cardiovascular events after acute myocardial infarction in patients with newly detected prediabetes (identified by oral glucose tolerance test, HbA1c or fasting glucose levels).
Descrição detalhada
The study is a national multicenter R-RCT associated to the The Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART registry) where participants, after informed consent, will be randomly assigned to either open treatment with standard care + metformin or standard care alone in a 1:1 ratio. Standard care consists of diet and life-style advice according to national guidelines but does not include metformin. Baseline data for individual patients will be collected from the SWEDEHEART registry. Patients will be followed per routine care at 2 and 12 months post index AMI and in addition at a final study visit at 24 months. Laboratory measurements and collection of SAE will be performed yearly. In total n=5150 patients is expected to be followed for major CV event (all-cause mortality, myocardial infarction, heart failure and stroke) by linkage with SWEDEHEART and national health registries.

Comparador ativoMetformin on top of standard care
Metformin will be prescribed by the Investigator at the study site and dispensed at pharmacy of choice by the patient. Metformin will be recommended to be gradually titrated to minimize gastrointestinal side effects with a start dose of 500 mg 1x1 for 1 week and thereafter 500 mg 1x2 with an individualised target dose of 2000 mg daily depending on tolerability. The goal is to a have minimal dose of 500 mg 1x2. Patients will be informed to stop medication in events of sever nausea, vomiting or dehydration according to standard practice. The threshold for metformin titration or adding another drug during follow-up is recommended to be assessed individually by the Investigator at the study site, responsible for the patient. Patients with eGFR \<60 cannot be included in the MIMET study. If GFR is between 30-45 ml/min during the study, metformin should be reduced to 1000 mg daily. Metformin is contraindicated if GFR \<30 ml/min. Standard care will be the same as in the control arm.
Metformina
Individualised target dose of 2000 mg daily depending on tolerability.
Nenhuma intervençãoStandard care alone
Standard care according to national guidelines. In Sweden there is no pharmacological intervention recommended for individuals with prediabetes at present. Standard care includes diet and life-style advice, which will be given to both groups in the same manner according to local routines, based on the present guidelines. Secondary preventive treatment includes physical activity, participating in exercise program, dietary habits, BMI and or waist circumference, smoking and EQ-5D will be followed in accordance with the routinely reported SWEDEHEART-SEPHIA variables.
