This is an additional qualitative concept elicitation interview-based study to further understand the patients' experience with Fabry disease and with the pegunigalsidase alfa administered intravenously every 4 weeks. Patients will be asked a set of open-ended questions with probes to describe their experiences with Fabry disease on treatment with pegunigalsidase alfa. Qualitative research methods will be used to obtain a deeper understanding of the patient experience by generating in-depth information about the experiences, perspectives, and feelings of patients and others, in their own words (FDA Patient-Focused Drug Development Guidance 2).
The study will be offered to the 29 patients participating in the BRIGHT-F51 clinical trial (NCT03614234).
