Summary
Brief summary
The purpose of this study is to investigate the efficacy and safety of two concentrations of

isotretinoin) in subjects 9 years of age and older for the treatment of congenital ichthyosis
(CI), including recessive X-linked ichthyosis (RXLI) and autosomal recessive congenital
ichthyosis-lamellar ichthyosis (ARCI-LI) subtypes.
