The objective of this study is to evaluate the long-term safety and efficacy of Ace-ER treatment in subjects with GNEM.
This Phase 3b extension study will assess the long-term safety of Ace-ER in patients who participated in and completed study UX001-CL301 (NCT02377921), study UX001-CL202 (NCT01830972), and study UX001-CL203 (NCT02731690).

Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious AEs (SAEs), and Discontinuations Due to AEs
An AE was defined as any untoward medical occurrence associated with the use of a drug, whether or not considered drug related. An SAE or serious suspected adverse reaction is an AE or suspected adverse reaction that at any dose, in the view of either the Investigator or Ultragenyx, results in any of the following outcomes: death; a life-threatening AE; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant incapacity or disability (substantial disruption of the ability to conduct normal life functions); congenital anomaly/birth defect. TEAEs were defined as any AE that occurred after the first dose of study drug. The severity of all AEs were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03: grade1=mild, grade 2=moderate, grade 3=severe, grade 4=life-threatening, grade 5=death.
Time frame: From first dose of study drug through the end of treatment plus 30 days (+5 days). Mean (SD) duration of treatment was 256.3 (101.54) days.
Change From Baseline in HHD UEC Score Over Time
Hand held dynamometry testing was used to measure strength. The maximum voluntary isometric contraction against a dynamometer was used to measure bilateral strength in the following muscle groups: shoulder abductors, wrist extensors and knee extensors. Specialized dynamometers for the measurement of grip and key pinch strength were also used. The total force (in kgf) for each was recorded. The UEC is derived from the sum of the average of the right and left total force (measured in kgf). Analyzed using a repeated measure generalized estimation equation (GEE) model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, 48
Change From Baseline in the GNEM-FAS Expanded Version Mobility Domain Score Over Time
GNEM-FAS Expanded Version Mobility subscale score has 13 items and ranges from 0 to 52 with higher scores representing greater mobility. Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, 48
Change From Baseline on the GNEM-FAS Upper Extremity Domain Score Over Time
GNEM-FAS Expanded Version Upper Extremity subscale score has 9 items and ranges from 0 to 36 with higher scores representing more skilled, independent use of the arms during functional activity performance. Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, 48
Change From Baseline in HHD Lower Extremity Composite (LEC) Score Over Time
Hand held dynamometry testing was used to measure strength. The maximum voluntary isometric contraction against a dynamometer was used to measure bilateral strength in the following muscle groups: shoulder abductors, wrist extensors and knee extensors. Specialized dynamometers for the measurement of grip and key pinch strength were also used. The total force (in kgf) for each was recorded. The LEC is derived from the sum of the average of the right and left total force (measured in kgf). Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, and 48
Change From Baseline in the Number of Stands in the Sit-to-Stand Test Over Time
Lower extremity function was assessed using a sit-to-stand test. The number of times the participant can rise from a seated to a standing position in a 30-second period was recorded. Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, and 48
Change From Baseline in Number of Lifts in the 30-Second Weighted Arm Lift Test Over Time
Upper extremity function was assessed using a weighted arm lift test performed bilaterally. The number of times the participant can raise a 1 kg weight above the head in a 30-second period was recorded. Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, and 48
Change From Baseline in Meters Walked in 6MWT Over Time
The total distance walked (meters) in a 6-minute period was measured. Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, and 48
Change From Baseline in Percent Predicted Meters Walked in 6MWT Over Time
The total distance walked (meters) in a 6-minute period was measured, and the percent predicted distance based on normative data for age and gender was estimated. Predicted 6MWT distance (meters) = 868.8 - (2.99 x Age) - (74.7 x Sex), where age is baseline age in years, and sex = 0 for males, and 1 for females. Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, and 48
Change From Baseline in Total Force in Knee Extensors Over Time
Hand held dynamometry testing was used to measure strength. The maximum voluntary isometric contraction against a dynamometer was used to measure bilateral strength in the following muscle groups: shoulder abductors, wrist extensors and knee extensors. Specialized dynamometers for the measurement of grip and key pinch strength were also used. The total force (in kgf) for each was recorded. Bilateral total force was defined as the average of the right and left force (measured in kgf). Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, and 48
Change From Baseline in Percent Predicted Total Force in Knee Extensors Over Time
The percent predicted total force value of lower extremity muscle strength in the knee extensors was determined based on reference equations adjusting for age, gender, height, and weight. Analyzed using a repeated measure GEE model, which includes the baseline value as a covariate.
Time frame: Baseline, Weeks 8, 16, 24, and 48
