Metformin Treatment for Children With Obesity-associated Asthma (MOACT)
The Role of Metformin in Asthma Control in Obese/Overweight Children, a Randomized Placebo Controlled Clinical Trial
The goal of this clinical trial is to learn if metformin can improve asthma control in overweight and obese children with mild, moderate, or severe asthma. It will also evaluate the safety and metabolic effects of metformin in this population. The main questions the study aims to answer are:
1) Does metformin improve asthma control, as measured by the Asthma Control Test (ACT) score? 2) Does metformin improve lung function, reduce asthma exacerbations, and improve metabolic and inflammatory markers in overweight/obese children with asthma? Researchers will compare metformin with a placebo (a look-alike substance that contains no active drug) to see if metformin improves asthma outcomes in overweight/obese children with asthma. Participants will take either metformin or a placebo in addition to their standard asthma treatment during the study period. They will attend scheduled clinic visits for asthma assessments, lung function testing, and safety monitoring. Blood, stool, and saliva samples, along with clinical information, will be collected from participants to assess asthma control, and markers related to metabolism and inflammation. Participants will also complete asthma control questionnaires and report medication use and asthma symptoms throughout the study period.

Assessing the impact of intervention treatment on change in asthma control test questionnaire (ACT) score after 26 weeks of intervention
Aikaikkuna: 26 weeks
|
The primary outcome measure is the change in the Asthma Control Test (ACT) score after 26 weeks of intervention. The ACT is a validated questionnaire used to assess asthma control, including symptoms such as cough, wheezing, use of bronchodilators, nocturnal symptoms, shortness of breath, and limitations in daily activities. For participants aged 12-17 years, the ACT score ranges from 0 to 25, where higher scores indicate better asthma control. Scores of 21-25 represent well-controlled asthma, 16-20 indicate poorly controlled asthma, and 0-15 indicate very poorly controlled asthma. For participants aged 4-11 years, the Childhood Asthma Control Test (C-ACT) score ranges from 0 to 27, where higher scores also indicate better asthma control. Scores of 21-27 represent well-controlled asthma, 13-20 indicate poorly controlled asthma, and 0-12 indicate very poorly controlled asthma. |
