Study to Evaluate the Safety, PK, PD, and Efficacy of PRX-102 in Japanese Patients With Fabry Disease (RISE)

Intervention / Treatment
Detailed Description
Investigators are doing this study to find out if treatment with pegunigalsidase alfa will prevent or reduce the development of health problems caused by Fabry disease and thereby improve patients' health and quality of life.
pegunigalsidase alfa (PRX-102) is a drug made using genetic engineering techniques and manufactured using cultured tobacco cells. It is given by intravenous infusion every 2 weeks, at a dosage of 1 milligram per kilogram (mg/kg) of body weight.
The study consists of a main study that is divided into two stages, each of which will last one year, followed by an optional extension study. In the optional extension stage, the participants may receive PRX-102 intravenous infusion every 2 weeks, at a dosage of 1 milligram per kilogram (mg/kg) of body weight or every 4 weeks at a dosage of 2 milligrams per kilogram (mg/kg) of body weight.
There are three groups (cohorts) in this study, with adults enrolled in either Cohort A or B and adolescents in Cohort C. Whether an adult is assigned to Cohort A or Cohort B depends on their kidney function and treatment history.
This study will start with a screening visit of up to 4 weeks. It will be followed up by infusion visits every 2 weeks or 4 weeks. For subjects not continuing in the extension stage, a follow-up call is to be made 30 days after the last study drug infusion.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion criteria (all subjects)
- Must have been born in Japan and have their biological parents and all 4 grandparents of Japanese descent
- A documented diagnosis of Fabry disease, as determined by the following:
- Males: Plasma and/or leukocyte alpha-galactosidase-A activity (by activity assay) that is ≤ 5% of mean normal laboratory levels or, if the enzymatic activity is above the 5% limit but still under the normal level, a confirmed disease-causing mutation of the GLA gene
- Females: Historical genetic test results consistent with Fabry mutations or, in the case of novel mutations, a first-degree male relative with Fabry disease
- All subjects: At least one of the following characteristic features of Fabry disease: neuropathic pain, cornea verticillata, and/or clustered angiokeratoma
- Estimated glomerular filtration rate (eGFR) at screening ≥40 mL/min/1.73 m2. For adults, this will be calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) Creatinine equation (2009); and for adolescents, it will be calculated using the Creatinine Cystatin C-based Chronic Kidney Disease in Children (CKiD) equation.
- Clinical condition that in the opinion of the Investigator requires treatment with ERT
Additional inclusion criteria for subjects in Cohort A
- Aged ≥18 to ≤60 years
- Treatment with agalsidase beta for at least the last 12 months, with the dose stable (defined as having received at least 80% of the labelled dose) for at least the last 6 months
- Diagnosis of kidney impairment, defined as a linear slope of eGFR more negative or equal to -2 mL/min/1.73 m2/year. The historical eGFR slope will be calculated based on at least 3 serum creatinine values obtained over the past 9 to 24 months prior to screening, using the CKD-EPI Creatinine equation (2009). This criterion will be confirmed at screening by calculating the screening eGFR slope using historical and screening serum creatinine values. Both historical and screening eGFR slopes will be used for the diagnosis of kidney impairment.
Additional inclusion criterion for subjects in Cohort B
- Aged ≥18 to ≤60 years
Additional inclusion criteria for subjects in Cohort C
- Aged ≥13 to <18 years
- If they previously received or are currently receiving ERT treatment, the subjects must be negative for anti-drug antibodies for PRX-102
Exclusion Criteria:
- Administration of ERT for Fabry disease within 14 days before baseline, or chaperone therapy for Fabry disease within 3 days before baseline
- History of type I hypersensitivity reactions (anaphylactic or anaphylactoid life-threatening reaction) to other ERT treatment for Fabry disease or to any component of the study drug
- Cohort A only: eGFR value of >90 to ≤120 mL/min/1.73 m2 at screening and a historical eGFR value >120 mL/min/1.73 m2 in the past 9 to 24 months before screening, indicating absence of renal impairment
- Urine protein to creatinine ratio (UPCR) >0.5 g/g (0.5 mg/mg or 500 mg/g) if not treated with an ACE inhibitor or ARB
- Initiation of treatment, or a change in dose to ongoing treatment, with an angiotensin-converting-enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) in the 4 weeks prior to screening.
- Currently taking another investigational drug for any condition
- Known non-pathogenic Fabry mutations
- History of renal dialysis or kidney transplantation
- History of acute kidney injury in the 12 months prior to screening, including specific kidney diseases (e.g., acute interstitial nephritis, acute glomerular and renal vasculitis); non-specific conditions (e.g., ischemia, toxic injury); as well as extrarenal pathology (e.g., prerenal azotemia, and acute postrenal obstructive nephropathy
- History of (or current) malignancy requiring treatment; the one exception is a prior history of resected basal cell carcinoma
- Severe cardiomyopathy or significant unstable cardiac disease within 6 months prior to screening
- A positive test for Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) within 3 months prior to screening, using a validated molecular assay or validated antigen assay
- Females: Pregnant or lactating, or of childbearing potential with a fertile male partner and unwilling to use a highly reliable method of contraception from the informed consent signature until 30 days after the last study treatment
- Presence of any medical, emotional, behavioral, or psychological condition that in the judgment of the Investigator could interfere with the subject's compliance with the requirements of the study
