Met Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: Active Metformin MedicationActive Control1 Intervention
The active metformin medication will be dosed in a weight-dependent manner. Liquid metformin (100mg/cc) will be provided to any participants unable to swallow the metformin capsules. For participants under 50kg at baseline, the initial dose will be 250mg once per day, and if this dose is well tolerated, they will increase each week by 250mg until a maximum dose of 1000mg daily is reached. For participants at and above 50kg at baseline, the initial dose will be 500mg once per day, and if this dose is well tolerated, they will increase each week by 500mg until a maximum dose of 2000mg daily is reached. After the 4-week titration period, each participant will continue dosing at his or her maximum tolerated dose daily for the remaining 12 weeks of the study.
Group II: Placebo MedicationPlacebo Group1 Intervention
The placebo will be dosed in a weight-dependent manner. Liquid placebo will be provided to any participants unable to swallow the placebo capsules. For participants under 50kg at baseline, the initial dose will be 250mg once per day, and if this dose is well tolerated, they will increase each week by 250mg until a maximum dose of 1000mg daily is reached. For participants at and above 50kg at baseline, the initial dose will be 500mg once per day, and if this dose is well tolerated, they will increase each week by 500mg until a maximum dose of 2000mg daily is reached. After the 4-week titration period, each participant will continue dosing at his or her maximum tolerated dose daily for the remaining 12 weeks of the study.
