Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPercentage of Adherence to the Scheduled Weekly Infusion by the Participants24 months
To determine the feasibility of giving weekly Laronidase for 2 years in patients with Hurler syndrome after allogeneic transplantation, compliance throughout the study with drug administration, the percentage of adherence to the scheduled weekly infusion for each participant is measured.
PrimaryNumber of Participants Experiencing Severe Adverse Events24 monthsNumber of participants experiencing severe adverse events that occur after administration with Laronidase to determine the feasibility of giving weekly Laronidase
SecondaryChanges in Growth VelocityBaseline, Month 24difference between baseline and month 24 growth velocities
SecondaryChange in Muscle Strength
Assessed from baseline every 6 months through 2 years; change between baseline and 24 months reported.If baseline and/or 24-month data were not available, the longest interval between measurements was reported, with a minimum requirement of 12 months
Handgrip strength is measured three times in both hands with a mechanical handheld Biodex System 3 dynamometer (Biodex medical Systems, Inc., Shirley, NY) with the subject in a seated position at each visit; the average for each hand is presented.
SecondaryChange in Peak Heart Rate to Monitor "Fitness"
Assessed from baseline every 6 months through 2 years; change between baseline and 24 months reported.If baseline and/or 24-month data were not available, the longest interval between measurements was reported, with a minimum requirement of 12 months
A modified Balke Treadmill Test was performed. Briefly, patients began walking at 2.0 mph with a 2% increase in grade every 2 min. A 12-lead electrocardiogram was monitored continuously throughout the test for the determination of heart rate and dysrhythmias or ischemic changes. Heart rate was measured at the end of each stage (i.e. every 2 min) .
SecondaryNumber of Participants Showing Improvements in Joint Range of Motion (ROM)
Assessed from baseline every 6 months through 2 years; change between baseline and 24 months reported.If baseline and/or 24-month data were not available, the longest interval between measurements was reported, with a minimum requirement of 12 months
Bilateral shoulder flexion, elbow extension, and hip extension were measured using goniometry. Improvements are defined for all joints as \>5°.
SecondaryShortening Fraction to Determine Systolic Cardiac FunctionBaseline and month 24
Cardiac ultrasounds were obtained at baseline and month 24. Two-dimensional imaging was obtained for determination of anatomy. Shortening fraction (SF \[normal \> 27%\]) was calculated by standard methods to determine the normal systolic cardiac function
SecondaryNumber of Participants With Changes in Cardiac Echo Structural ParametersBaseline and month 24Pulse-wave and color Doppler interrogation of cardiac valves was performed for determination of valve regurgitation
SecondaryCorrelation of 6 Minute Walk Test With Anti-laronidase Antibody + Status
Assessed from baseline every 6 months through 2 years; change between baseline and 24 months reported.If baseline and/or 24-month data were not available, the longest interval between measurements was reported, with a minimum requirement of 12 months
6 minute walk test (6MWT) was performed to assess overall physical function and health status. In brief, a 30m hospital corridor marked by colored tape at each end was used. Subjects were instructed to walk from end to end at their self-selected pace, while attempting to cover as much distance as possible in the 6 min. The patients were instructed to walk around the mark as they changed direction. The time and distance covered was recorded, as was the heart rate prior to and immediately after completion of the walk test. To find the association between the rate of change in 6MWT, and anti drug antibody (ADA) titer, a statistical test is performed adjusting for age at the time of enrollment.
