Metformin Treatment for Children With Obesity-associated Asthma (MOACT)

30 de maio de 2026 atualizado por: Prof Ibrahim Janahi

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.

Descrição detalhada

The study is a randomized, double-blinded, placebo-controlled, parallel- group intervention trial aimed to recruit 182 overweight/obese children aged 10-17 years with mild, moderate, or severe persistent asthma from the outpatient Pediatric Pulmonology Department at Sidra Medicine, Qatar. Participants will be randomly assigned in a 1:1 ratio to receive either metformin or placebo for the intervention period of 26 weeks. The primary outcome is defined as an increase in the Asthma Control Test (ACT) score at the end of the treatment compared with baseline. Secondary outcomes include a decrease in annual rate of asthma exacerbations and corticosteroid use, as well as change in lung function, and pediatric asthma quality of life questionnaire (PAQLQ) score from baseline. Exploratory outcomes include changes in the body mass index, clinical parameters, plasma cytokine profile, plasma metabolomic and lipidomic profile, blood transcriptomic profile, and microbiome of gut and saliva after metformin/placebo intervention. Statistical analyses of all primary and secondary end points will be performed using intention-to-treat (ITT) principle and per protocol (PP) approaches.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Assessing the impact of intervention treatment on change in asthma control test questionnaire (ACT) score after 26 weeks of intervention
Prazo: 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.

Prazo: 26 weeks
Forced expiratory volume in 1 second (FEV1) after 26 weeks of intervention, assessed as percent predicted FEV1 measured by spirometry; higher percent predicted FEV1 values indicate better pulmonary function and improved asthma control.
26 weeks
Assessing the impact of intervention treatment on forced vital capacity (FVC) after 26 weeks of intervention
Prazo: 26 weeks
Forced vital capacity (FVC) after 26 weeks of intervention, assessed as percent predicted FVC measured by spirometry; higher percent predicted FVC values indicate better lung function and improved respiratory capacity.

Prazo: 26 weeks
Pediatric Asthma Quality of Life Questionnaire (PAQLQ) scores after 26 weeks of intervention, assessed using the validated PAQLQ instrument; which measures both physical and emotional impact of asthma. The questionnaire has three domains including asthma symptoms (6 items), emotional function (4 items) and activity limitation (3 items), scale ranging from 1 to 7, where higher scores indicate better quality of life and improved symptom control.
