Brief Summary:
This study will test the effectiveness of two different treatments for children and adolescents who have gained weight on their antipsychotic medications.
Detailed Description:
Disorders that involve severe dysregulation of mood or thoughts in children -- such as early onset bipolar spectrum (BPS) and schizophrenia spectrum (SS) disorders -- are commonly treated with antipsychotic medications. However, many of the newest and most commonly prescribed antipsychotic medications can cause weight gain and metabolic dysfunctions. Use of these newer antipsychotics, called second generation antipsychotics (SGAs), is increasing rapidly in children, and the risk of weight gain from SGAs is higher among children than adults. Excessive weight gain can lead to obesity, which, in turn, can lead to increased health care costs, increased risk of sickness, and lower life expectancy. These factors are enhanced in children and adolescents who grow up obese.
Two different strategies to reduce weight gain and metabolic side effects from SGAs will be tested in this study. The first strategy involves switching from the current SGA to a lower risk agent (aripiprazole or perphenazine) hypothesized to result in weight loss and improved metabolic functioning. The second strategy involves taking the medication metformin in addition to the current SGA. Metformin is approved by the Food and Drug Administration (FDA) to promote weight loss in youth with diabetes and has been effective in reducing weight in youth taking SGAs.
Participation in this study will last between 26 and 27 weeks and will be divided into two parts. The first part will last 2 to 3 weeks and include three study visits. During this part, participants will undergo a physical exam, an electrocardiogram (EKG), a dual energy X-ray absorptiometry (DXA) test, and blood tests. The DXA measures body fat.
The second part will last 24 weeks and include nine study visits. During this part, participants will be randomly assigned to one of three conditions: gradual switch of current SGA medication to either aripiprazole or perphenazine, addition of metformin to current SGA medication, or no change to treatment with current SGA medication. Visits will take place on Weeks 1, 2, 4, 6, 8, 12, 16, 20, and 24. At each visit, participants will meet with a study doctor who will assess symptoms and side effects, and participants and their guardians will receive information and recommendations about childhood obesity and weight loss. There will also be monthly urine pregnancy tests, and two blood tests.
