Pharmacokinetic/Pharmacodynamic Study of 2 agalsidase beta Formulations in Single Dose Administered to Healthy Volunteers as intravenous infusion, at a concentration of 1 mg/kg
Volunteers will receive either one or the other agalsidase beta formulation. Drug will be administered as an intravenous 5h infusion. Plasma samples will be taken at different time points, from before infusion up to 12h later. Pharmacokinetic (PK) and pharmacodynamic (PD) profile will be determined, and bioequivalence evaluated.

Maximum Serum Concentration of Agalsidase Beta (Cmax)
Compare the maximum serum concentration of two formulations of agalsidase beta after intravenous infusion of 1 mg/kg: * Fabrazyme (Sanofi-Genzyme) (Reference Formulation, "R") * Agalsidase beta from Biosidus SA (Test Formulation, "T")
Time frame: 0, 1, 3, 5, 5.5, 6, 7, 8, 10 and 12 hours from the beginning of the infusion
Area Under the Curve of Serum Concentration Between Times 0 and 12 Hours of Agalsidase Beta
Compare the area under the curve between times 0 and 12 hours of two formulations of agalsidase beta after intravenous infusion of 1 mg/kg: * Fabrazyme (Sanofi-Genzyme) (Reference Formulation, "R") * Agalsidase beta from Biosidus SA (Test Formulation, "T")
Time frame: 0, 1, 3, 5, 5.5, 6, 7, 8, 10 and 12 hours from the beginning of the infusion
Time at Which Maximum Serum Concentration of Agalsidase Beta is Observed (Tmax)
Compare the time at which maximum serum concentration of agalsidase beta is observed of two formulations of agalsidase beta after intravenous infusion of 1 mg/kg: * Fabrazyme (Sanofi-Genzyme) (Reference Formulation, "R") * Agalsidase beta from Biosidus SA (Test Formulation, "T")
Time frame: 0, 1, 3, 5, 5.5, 6, 7, 8, 10 and 12 hours from the beginning of the infusion
Area Under the Curve of Serum Concentration, Resulting From the Extrapolation From Time 0 to Infinite Time
Compare the area under the curve of serum concentration, resulting from the extrapolation from time 0 to infinite time of two formulations of agalsidase beta after intravenous infusion of 1 mg/kg: * Fabrazyme (Sanofi-Genzyme) (Reference Formulation, "R") * Agalsidase beta from Biosidus SA (Test Formulation, "T")
Time frame: 0, 1, 3, 5, 5.5, 6, 7, 8, 10 and 12 hours from the beginning of the infusion
Enzymatic Activity on Plasma Samples Measured With Fluorometric Method
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Comparison between enzymatic activity of both formulations of agalsidase beta, assessing the difference between the 5 hour timepoint and the basal determination, to estimate their biological activity as part of the pharmacodynamic analysis. A fluorometric assay will be used. The enzymatic activity will be measured in mU/ml. The variation of enzymatic activity between the sample taken at the end of the infusion (5 hours) and pre-infusion will be analyzed.
Time frame: Pre-infusion and 5 hours post administration (end of infusion)
Number of Patients With Adverse Events
Evaluation of the product safety with analysis of incidence of adverse events and tolerance.
Time frame: From infusion to 35 days after
Number of Participants With Positive Results for the Presence of Neutralizing Antibodies Against Agalsidase Beta
The presence of neutralizing antibodies to agalsidase beta activity was analyzed in serum samples from 24 volunteers (0h, 12h and 35 days), by biological activity neutralization method. The percentage of inhibition in the samples was calculated by comparing the activity value of 1 ng of agalsidase beta alone with that of agalsidase treated with the serum samples. Those samples with percentage inhibition \>50% were defined as positive.
Time frame: 0 hours,12 hours and 35 days after the end of the infusion.
