Previously, six XLHED-affected boys received the ER004 treatment
before birth (pre-natal treatment). After birth, all six babies showed improvement in some symptoms, particularly regarding their ability to sweat.
Some of these results have been reported in a scientific journal (N Engl J Med 2018; 378:1604-1610
These prenatal treatments using ER004 indicated the potential of this experimental medicine to prevent or at least significantly reduce the severity of some XLHED symptoms.
