I don't think this is such good news', since the objective wasn't met:
Objective of the study:
Young adults with type 1 diabetes mellitus (T1DM) have increased glomerular filtration rate (GFR), which may mediate progressive renal disease and microalbuminuria. This may be secondary to low concentrations of insulin-like growth factor (IGF)-I and GH hypersecretion. We tested the hypothesis that restoration of circulating IGF-I concentrations in young adults with T1DM might suppress GH secretion, GFR and urinary albumin excretion.
Conclusion:
.....but there was no effect on glomerular hyperfiltration or albumin excretion rates......
