Fabry Patient's Experience Of PegunigaLsidasE Alfa Monthly Infusion

Fabry Patient's Experience Of PegunigaLsidasE Alfa Monthly Infusion - PEOPLE Study

Pegunigalsidase alfa (PRX-102) is a long-term enzyme replacement therapy design for the treatment of patients with Fabry disease. Although in the clinical development program patient-reported outcomes and clinician-reported outcomes have been included, this may not allow for a sufficiently accurate assessment of the quality of life in patients with Fabry Disease treated with pegunigalsidase alfa.

This study will collect the patient experience on the pegunigalsidase alfa treatment administered intravenously every 4 weeks in the BRIGHT-F51 clinical study (NCT03614234).

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).
