Nogle af undersøgelserne omfattede også børn, der havde fejl i genet for væksthormon eller havde dannet antistoffer (inhibitorer) mod væksthormon, da INCRELEX også kunne anvendes til behandling af sådanne patienter.
Some of the studies had also included children who had defects in the gene for GH and who had developed antibodies (inhibitors) against GH, as INCRELEX could also be used to treat such patients.
