Brief Summary:
The aim of this study is to evaluate the effectiveness safety and tolerability of metformin treatment in children and adolescents suffering from weight gain secondary to use of atypical antipsychotic medications In this 12 week open-label study we will investigate metformins effects on weight control andor weight loss We hypothesize that metformin would prevent further weight gain or lead to weight loss resulting in amelioration of one of the most significant side effects of atypical antipsychotic use
Detailed Description:
Patients taking olanzapine risperidone or quetiapine with increased BMI of at least 10 over the previous 2 months of atypical therapy will be eligible for the study Subjects will need to have been on a stable dose of their antipsychotic medications at the time of enrollment stable x2 weeks and will remain on the same atypical dose if possible throughout the study The dosing of metformin will start at 500mg per day and increase up to a maximum dose of 1500mg daily Determination of weight gain during the course of the study will be based on the subjects weight at enrollment and subsequent visits The patients will be asked not to vary their dietary or physical activity habits during the study
Interpretation of Data The studys primary outcome measure will be change in weight and body mass index at 12 weeks of metformin treatment Additionally skin-fold test and abdominal girth will be measured at baseline and endpoint
Risks Generally metformin is well-tolerated However there may be unknown risks associated with exposure to a new medication in a clinical population where this specific compound has not been studied extensively The general and rare side effects are listed below These risks will be minimized by careful monitoring and higher than standard of care safety evaluations In addition an individuals symptoms could potentially remain unchanged or worsen by initiating this medication or from delaying initiation of a potentially more effective alternative treatment For these reasons participation in the study is entirely voluntary and consent may be withdrawn at any time without any repercussions and will result in the patient being immediately discontinued from the study If at any time the clinician believes that the patient is not benefiting from the study the study will be discontinued and endpoint measures will be obtained if possible A risk-benefit analysis weighing clinical improvement against side effects will be done at each visit and will determine further inclusion in the study
Subjects and their guardians will be asked repeatedly to inform study staff of any side effects Subjects are informed of the potential side effects and the importance of alerting study staff to the side effects in the consent and assent forms Side effect data will be collected at baseline and every other week but subjects are encouraged to give relevant information at every clinical evaluation
Alternative treatments include no treatment with an attendant risk of increased weight gain potentially leading to health hazard Other medications that are available are not extensively used and widely accepted These other medication options will be discussed as alternatives during the consent process Also life-style modifications including healthy diet habits and increased physical activity will be discussed during the consent process as well
