Switch Over Study of Biosimilar AGA for Fabry Disease
20 patients around the world
Available in Argentina
BIO-AGA-Fase III-001 is a Phase III, prospective, multicenter, open-label, single-group,
baseline-controlled, switch over clinical trial to evaluate the efficacy and safety of AGA
BETA BS in patients with FD already treated and previously stabilized with Fabrazyme®.
The study will be conducted in 2 parts: a 5-week Lead-in period (period 1) and 54 week
treatment period (period 2). During period 1 all participants will receive 2 intravenous (IV)
infusions of Fabrazyme®, provided by Biosidus. After that, in period 2 all participants will
switch treatment to AGA BETA BS.
A total of up to 20 participants are planned for the study.
•The primary objective of the study is to evaluate the equivalence in efficacy between AGA
BETA BS and Fabrazyme® after 6 months of treatment in participants with Fabry disease
previously stabilized with Fabrazyme, by measuring disease biomarker (mean plasma Lyso-Gb3
marker ratio after 26 weeks of treatment, defined as plasma level of the marker Lyso-Gb3
after 26 weeks (6 months) divided by plasma level of the marker Lyso-Gb3 at baseline).

The remaining percentage will consist of male late onset and classic women FD phenotype.Participants who have been on stable Fabrazyme® treatment for at least 6 months prior to Baseline visit.Patients that in the last 3 months before the baseline visit have been receiving ≥80% of Fabrazyme®'s labeled dose/kg, this calculation includes both infusions provided by Biosidus during the Lead in period.Disease status considered clinically stabilized, at Investigators' discretion.Estimated glomerular filtration rate (eGFR) ≥45 mL/minute/1.73 m2 by CKD-EPI equation at Screening visit.If receiving pain killers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs), participants must be in a stable dose for ≥ 4 weeks.
- Chronic kidney disease in stage 3b, 4, or 5.History of dialysis, kidney transplant or participants who are on the waiting list for a kidney transplant.Proteinuria ≥1 g/day at screening.Participants who have suffered a clinical cardiovascular event (such as but not limited to myocardial infarction, transient ischemic attack) within 6 months prior to Screening visit.Participants who have clinically significant unstable cardiac disease (such as but not limited to uncontrolled symptomatic arrhythmia, unstable angina, congestive heart failure New York Heart Association class III or IV).Participants who have suffered a clinical cerebrovascular event (such as but not limited to stroke, transient ischemic attack) within 6 months prior to Screening visit.History of anaphylaxis or other type I hypersensitivity reactions to agalsidase beta.History of acute kidney injury in the 12 months prior to Screening visit (such as but not limited to acute interstitial nephritis, acute renal failure of glomerular origin or caused by vasculitis).Presence of any medical, emotional, behavioral, or psychological condition that, according to the Investigator, would interfere with the participant's compliance with the requirements of the study.Treatment initiation or change of dose of ACE inhibitors or ARBs in the 4 weeks before the screening.Current participation in an interventional study, in which the participant received any drug within 90 days before the Screening visit.
