| Scientific title | Effects of metformin on cardiovascular risk factors in prepubertal children born small for gestational age without postnatal catch-up growth, currently treated with growth hormone: a prospective randomised clinical trial |
| Study acronym | GH-MET |
| Study hypothesis | In prepubertal small for gestational age (SGA) children treated with growth hormone (GH), the addition of metformin will have beneficial effects on cardiovascular risk markers and body composition. |
| Ethics approval(s) | Ethical Committee of Hospital Sant Joan de Deu, University of Barcelona, approved on the 2nd February 2010 |
| Condition | Short children born small for gestational age |
| Intervention | Administration of metformin (425 mg/d) or placebo per oral once daily (at night) over 12 months. Total duration of follow-up is 18 months. |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | Metformin |
| Primary outcome measure | Insulin sensitivity (homeostatic model assessment [HOMA]), fasting insulin and visceral fat. An increase in insulin sensitivity (estimated using the HOMA method) equal or greater than 30%, accompanied by a decrease of 10% in visceral fat mass, will be considered a positive and discriminative response. Measured at baseline, 9 months and 18 months. |
| Secondary outcome measures | 1. Pubertal onset (girls) 2. Insulin-like growth factor-1 (IGF-1) 3. Intima-media thickness (IMT) 4. Lipid profile (triglycerides) 5. Adipokines Measured at baseline, 9 months and 18 months. |
