Change From Baseline in 36-Item Short Form (SF-36) Health Survey Scores at Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8 and Year 9 at End of Study
The SF-36 questionnaire, version 2, investigates the participant's health-related quality of life (HRQL). It is a 36-item questionnaire measuring 8 domains (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health). Each domain score ranges from 0 (worst) to 100 (best), with higher scores reflecting best health-related quality of life. Two summary scale scores were computed from the 8 domain scores: the Physical Component Summary and the Mental Component Summary. Score range for both summary scale ranges from 0 (worst) to 100 (best), with higher scores reflecting best health-related quality of life.
Change From Baseline in Fatigue Severity Scale (FSS) Scores at Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study
The FSS is an instrument consisting of 9 self-administered questions that measures the impact of severity of fatigue symptoms on everyday functioning, based on the recall over the past week. Score range for each question ranges from 1 (minimum) to 7 (maximum), where higher score indicates greater severity. FSS total score was calculated by averaging the results of all questions. Total FSS score ranges from 9 (minimum) to 63 (maximum), where higher scores indicates greater severity.
Number of Participants With Bone Pain Levels During the Past 4 Weeks at Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study
Bone pain was assessed as a part of Gaucher disease assessment in participants. Participants were categorized as none (no bone pain), very mild bone pain, mild bone pain and moderate bone pain. In this outcome, number of participants with different levels of bone pain at specified time points were reported.
Number of Participants With Mobility Status (MS) at Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study
Mobillity, i.e. ability to walk was assessed as a part of Gaucher disease assessment in participants.In this outcome, number of participants with their different mobility status (unrestricted mobility, walks with difficulty) at specified time points were reported.
Number of Participants With No Bone Crisis at Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study
Bone crisis was assessed as a part of Gaucher disease assessment in participants. Acute, excruciating episodic bone pain is characteristic of Gaucher bone crisis, which typically causes debilitation lasting several days or longer and requires treatment with immobilization, hydration, and opioid analgesics. Participants were categorized as 0= no bone crisis, 1= 1 bone crisis, and 2= 2 bone crises during the assessment period. In this outcome, number of participants with 0= no bone crises levels at specified time points were reported.
Bone Marrow Infiltration: Number of Participants With Improvement From Baseline in Dark Marrow at Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8 and at End of Study (EOS)
Bone marrow infiltration assessments were designed to evaluate improvements in dark marrow using MRI. Each MRI assessment was performed for both femurs and consisted of reviewing 6 different zones (the femoral head, greater trochanter, intertrochanteric region, shaft, distal metaphysis, and condyles). MRI images recorded dark marrow for each zone as either present or not present at baseline. In this outcome, number of participants (for whom dark marrow was present at baseline) with improvement from baseline in dark marrow at each specified time point were reported.
Lumbar Spine and Femur T-Scores for Bone Mineral Density (BMD) at Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study
Images of the lumbar spine and femur were obtained by dual energy X-ray absorptiometry (DXA) to determine T-score for each bone area and total bone mineral density. T-scores compares participant's bone density with that of healthy young participant of same gender. The T-score bone density categories were: normal (score >-1), osteopenia (score -2.5 to <=-1), and osteoporosis (score <= -2.5).
Lumbar Spine and Femur Z-Scores for BMD at Baseline, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6, Year 7, Year 8, Year 9 and at End of Study
Images of the lumbar spine and femur were obtained by DXA to determine Z-score for each bone area and total bone mineral density. The Z-score bone density categories are: normal (score >-2) and below normal (score <=-2).
