Who can join

Age: 18 and older, up to 49. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• The participant was greater than equal to (>=) 18 years of age and less than (<) 50 years of age.
• The participant was male.
• The participant had provided a signed informed consent.
• The participant had a confirmed diagnosis of Fabry disease as documented by leukocyte α- Galactosidase A (αGAL) activity of <4 nanomole/hour/milligram (nmol/hr/mg) leukocyte (preferred assay; results from a central laboratory) or plasma αGAL <1.5 nanomole/hour/milliliter (nmol/hr/mL) (results from a central laboratory).
• The participant had a plasma globotriaosylsphingosine (lyso-GL3) >=65 nanogram per milliliter (ng/mL).
• The participant had never been treated with a Fabry disease-specific treatment.
• If the participant was on renin-angiotensin-aldosterone system (RAAS) blockers and antidepressants, the dose should be stable (i.e., prescribed dose and frequency) for at least the immediate 3 months prior to screening.

You may not qualify if…

• The participant had an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m\^2 using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI).
• The participant had a median urine protein/creatinine ratio (PCR) >=0.5 gram per gram (g/g) (median of 3 overnight urine collections. Collection of each of the 3 samples must occur between 4 and 7 days of each other, and all samples must be collected within a 15 day period). All 3 samples must be collected regardless of the results and results available prior to Day 1.
• The participant had undergone a kidney transplant.
• The participant had either active or a history of clinically significant organic disease (with the exception of the symptoms related to Fabry disease), including clinically significant cardiovascular, hepatic, pulmonary, hematologic, neurological or renal disease, or other medical condition, serious inter-current illness, or extenuating circumstances that, in the opinion of the Investigator, would preclude participation in the trial.
• The participant had abnormal liver function (serum total bilirubin > the upper limit of normal, or serum alanine aminotransferase ([ALT] and aspartate aminotransferase [AST] >2.0 times the upper limit of normal).
• The participant had, according to World Health Organization (WHO) grading a cortical cataract (COR) > one-quarter of the lens circumference (Grade COR-2) or a posterior subcapsular cataract (PSC) >2 millimeter (mm) (Grade PSC-2). Participants with nuclear cataracts were not excluded.
• The participant was currently receiving potentially cataractogenic medications.
• The participant had received strong or moderate inducers or inhibitors of Cytochrome P450 3A4 (CYP3A4) per Food and Drug Administration (FDA) classification within 14 days prior to enrollment or within 5 times the elimination half-life or PD half-life of the medication, whichever is longer.
• The participant was scheduled for in-patient hospitalization, including elective surgery, during the study.
• The participant had a positive result on any of the following tests: hepatitis B surface antigen (HBsAg), anti-hepatitis C virus (anti-HCV) antibodies, anti-human immunodeficiency virus 1 and 2 antibodies (anti-HIV1 and anti-HIV2 Ab). Participants with a positive hepatitis B surface antibody (HBsAb) test with a history of prior hepatitis B immunization were eligible if other criteria met (i.e., negative tests for: HBsAg, hepatitis B core antibody [HBcAb], and hepatitis C virus antibody [HCVAb]).
• The participant had participated in a study involving an investigational drug within the past 30 days of the start of the trial.
• The participant was unwilling to comply with the requirements of the protocol.
• The participant was a sexually active man who was not willing to use 2 forms of birth control including a barrier method during the study until 6 weeks after the last treatment with investigational medicinal product (IMP).
• The participant had a history or ongoing clinically significant cardiac arrhythmia, defined as either atrial fibrillation, sustained or non-sustained ventricular tachycardia.
• The participant had any contraindication to magnetic resonance imaging (MRI).
• The participant had one of the following central nervous system exclusion criteria:
• Acute stroke, within 3 months of the screening visit.
• History of seizures.
• The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
