Thank you for your interest in this study of an investigational topical lotion for Netherton's. In order to determine if you pre-qualify for this research study, we will ask you a few questions about your skin and treatments you may have tried. You may stop answering at any time and do not need to answer any questions that make you feel uncomfortable. All information you provide will be kept conﬁdential and stored in the secured study database if you are enrolled in the study. If you will not qualify for the study, your information will also be kept in the secured database until the end of the study and then destroyed unless you elect to have us retain your information for potential future trials (see question 14 below).
