E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the ongoing safety, tolerability, and efficacy parameters of 1 mg/kg pegunigalsidase alfa (PRX-102) every other week in adult Fabry patients who have successfully completed studies PB-102-F20 or PB-102-F30, or completed at least 48 months in study PB-102-F03. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Completion of study PB-102-F20 or PB-102-F30, or completed at least 48 months in study PB-102-F03.
2. The patient signs informed consent
3. Female patients and male patients whose co-partners are of child-bearing potential agree to use a medically acceptable method of contraception, not including the rhythm method. Acceptable methods of contraception include hormonal products, intrauterine device, or male or female condoms. Contraception should be used for 1 month after treatment termination. |
|
E.4 | Principal exclusion criteria |
1. Presence of any medical, emotional, behavioral or psychological condition that, in the judgment of the Investigator and/or Medical Director, would interfere with patient compliance with the requirements of the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
SAFETY ENDPOINTS:
Changes from baseline in:
*Clinical laboratory tests
*Physical examination
*Assessment of the injection site
*Electrocardiography (ECG)
*Treatment-emergent adverse events (TEAE)
*Ability to taper off infusion pre-medication at the start of the study
*Requirement for use of pre-medication overall to manage infusion reactions
*Treatment-emergent anti-pegunigalsidase alfa antibodies |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Patients who received at least one dose of study drug will be included in the safety analysis. Results of safety evaluations (including TEAEs, injection site reactions, physical examinations, ECG, and laboratory analyses, anti-drug antibodies) will be summarized and described.
No formal statistical analyses will be performed. The study endpoints will be evaluated by various summary analyses by study visit and by change from baseline data for each efficacy endpoint. Safety and efficacy endpoints will be compared to baseline using summary statistics. Data will not be analysed by inferential statistics.
An interim analysis may be performed for administrative purposes during the course of the study; available efficacy and safety parameters will be summarized using descriptive statistics. |
|
E.5.2 | Secondary end point(s) |
EFFICACY ENDPOINTS:
*Estimated glomerular filtration rate (eGFRCKD-EPI)
*Left Ventricular Mass Index (g/m2) by magnetic resonance imaging (MRI)
*Plasma Lyso-Gb3
*Plasma Gb3 concentration
*Protein/Creatinine ratio, spot urine test (UPCR)
*Frequency of pain medication use
*Exercise tolerance (Stress Test)
*Short Form Brief Pain Inventory (BPI)
*Mainz Severity Score Index (MSSI)
*Quality of life (EQ-5D-5L)
*Fabry disease clinical events
