Interventions

DRUG

Metformin

Metformin will be dispensed in a liquid suspension of 100 mg/mL. For children 6-9 years of age, metformin will be started at 250 mg at their evening meal for 1 week, followed by the addition of a 250 mg dose at breakfast for 1 week. At the Week 2 visit, if metformin is well-tolerated, the dose will be increased to 500 mg twice daily. For children from 10-17 years of age, metformin will be started at 250 mg at their evening meal for 1 week, followed by the addition of a 250 mg dose at breakfast for 1 week. At the Week 2 visit, if metformin is well-tolerated, the dose will be increased to 500 mg twice daily. At the Week 4 visit, if metformin is well-tolerated, the dose will be increased to 850 mg twice daily.

DRUG

Placebo

The placebo hydrochloride oral solution will be prepared to match the appearance, smell and taste of the metformin as closely as possible. For children from 6-9 years of age, placebo will be started at 250 mg at their evening meal for 1 week, followed by the addition of a 250 mg dose at breakfast for 1 week. At the Week 2 visit, if placebo is well-tolerated, the dose will be increased to 500 mg twice daily. For children from 10-17 years of age, placebo will be started at 250 mg at their evening meal for 1 week, followed by the addition of a 250 mg dose at breakfast for 1 week. At the Week 2 visit, if placebo is well-tolerated, the dose will be increased to 500 mg twice daily. At the Week 4 visit, if placebo is well-tolerated, the dose will be increased to 850 mg twice daily.
