T1  - Time to treatment benefit for adult patients with Fabry disease receiving agalsidase beta: data from the Fabry Registry
JF  - Journal of Medical Genetics
N2  - Background 
Agalsidase beta is a form of enzyme replacement therapy for Fabry disease, a genetic disorder characterised by low alpha-galactosidase A activity, accumulation of glycosphingolipids and life-threatening cardiovascular, renal and cerebrovascular events. In clinical trials, agalsidase beta cleared glycolipid deposits from endothelial cells within 6 months; clearance from other cell types required sustained treatment. We hypothesised that there might be a 'lag time' to clinical benefit after initiating agalsidase beta treatment, and analysed the incidence of severe clinical events over time in patients receiving agalsidase beta. 

Methods 
The incidence of severe clinical events (renal failure, cardiac events, stroke, death) was studied in 1044 adult patients (641 men, 403 women) enrolled in the Fabry Registry who received agalsidase beta (average dose 1 mg/kg every 2 weeks) for up to 5 years. 

Results 
The incidence of all severe clinical events was 111 per 1000 person-years (95% CI 84 to 145) during the first 6 months. After 6 months, the incidence decreased and remained stable within the range of 40-58 events per 1000 patient-years. The largest decrease in incidence rates was among male patients and those aged >= 40 years when agalsidase beta was initiated. 

Conclusions 
Contrary to the expected increased incidence of severe clinical events with time, adult patients with Fabry disease had decreased incidence of severe clinical events after 6 months treatment with agalsidase beta 1 mg/kg every 2 weeks.
