  • Research summary

    The purpose of this research study is to test the experimental drug called PRX-102 as an enzyme replacement therapy for Fabry disease. Fabry disease is a rare, inherited disease caused by the deficiency of a certain enzyme which results in reduced kidney function. Patients who are currently being treated with a standard enzyme replacement
    therapy called agalsidase alfa (also known as REPLAGAL®) will be invited to participate in the study. This is an open label switch over study to assess the safety and effectiveness of PRX-102 for the treatment of Fabry disease. Patients treated with agalsidase alfa for at least 2 years and on a stable dose for at least 6 months, will be screened and evaluated over 3 months while continuing on agalsidase alfa. Following the screening period, the patient will be enrolled and switched from their agalsidase alfa treatment to receive intravenous (IV) infusions of PRX-102 1 mg/kg every two weeks for 12 months. No more than 25% of treated patients will be female.

    22 participants will take part in the study globally, with a target of 8 participants to be recruited in the UK amoungst 3 research sites.

    At the time of enrolment, premedication, if used for the agalsidase alfa infusions before enrolment, will be continued through the first infusion with PRX-102 and then will be gradually tapered at the investigator’s discretion during the first 2 months. The first infusions of PRX-102 will be administered under controlled conditions at the investigation site. In this study, there is the option that patient can receive their PRX-102 infusions at a home care setup once the investigator and Sponsor Medical Director agree that it is safe to do so. Home care set up would only be set up if this is a feasible and safe option.
