Substrate replacement therapy is a potential therapeutic strategy based on the success of replacing missing SA and reducing muscle disease in a relevant mouse model of the human disease (Malicdan et al., 2009). Successful use of SA replacement therapy in humans is believed to depend upon providing steady long-term exposure to the compound in an extended release form (such as Sialic Acid-Extended Release [SA-ER]), given SA's short half-life. Following a Phase 1 study to establish the pharmacokinetics (PK) for SA-ER, Ultragenyx is conducting this study to assess the dose and potential pharmacodynamic effect of restoring sialylation of muscle by treatment with SA-ER at two dose levels as compared to placebo when administered over two 24 week periods of time. The study will also evaluate safety, as well as the effect of SA-ER on clinical measures of muscle strength, mobility, function and self-reported disability and quality of life. Effects on muscle volume/mass and function and on serum biomarkers will be evaluated as exploratory measures. These data should allow the selection of a dose and the appropriate design for a Phase 3 clinical study." }, "ConditionsModule":{ "ConditionList":{ "Condition":[ "GNE Myopathy", "Hereditary Inclusion Body Myopathy" ] }, "KeywordList":{ "Keyword":[ "Hereditary Inclusion Body Myopathy (HIBM)", "GNE myopathies", "distal myopathy with rimmed vacuoles [DMRV]", "Nonaka disease" ] } }, "DesignModule":{ "StudyType":"Interventional", "PhaseList":{ "Phase":[ "Phase 2" ] }, "DesignInfo":{ "DesignAllocation":"Randomized", "DesignInterventionModel":"Parallel Assignment", "DesignPrimaryPurpose":"Treatment", "DesignMaskingInfo":{ "DesignMasking":"Quadruple", "DesignWhoMaskedList":{ "DesignWhoMasked":[ "Participant", "Care Provider", "Investigator", "Outcomes Assessor" ] } } }, "EnrollmentInfo":{ "EnrollmentCount":"46", "EnrollmentType":"Actual" } }, "ArmsInterventionsModule":{ "ArmGroupList":{ "ArmGroup":[ { "ArmGroupLabel":"6,000 mg SA-ER", "ArmGroupType":"Experimental", "ArmGroupDescription":"Subjects will receive this dose for the duration of the study (total study duration of 48 weeks).", "ArmGroupInterventionList":{ "ArmGroupInterventionName":[ "Drug: Sialic Acid Extended Release (SA-ER)" ] } },{ "ArmGroupLabel":"Placebo", "ArmGroupType":"Placebo Comparator", "ArmGroupDescription":"Subjects will be randomized to the placebo arm for the first 24 weeks of the study.

Genotyping will not be conducted in this protocol.\nMust be able to walk 20 meters independently (may use orthotics and assistive devices).\nMust be able to provide reproducible force in bilateral elbow flexors and knee extensors during hand-held dynamometry testing (unilateral between test variability of < 15% for both muscle groups).\nMust be willing and able to comply with all study procedures including fine needle muscle biopsies of the upper (e.g., triceps brachii or posterior deltoid) and lower (e.g., biceps femoris or vastus lateralis) extremities at Baseline and 24 and 48 weeks.\nSexually active subjects must be willing to use an acceptable method of contraception while participating in the study.\nFemales of childbearing potential must have a negative pregnancy test at Screening and be willing to have additional pregnancy tests during the study. Females considered not of childbearing potential include those who have been in menopause for at least two years, or have had tubal ligation at least one year prior to Screening, or who have had total hysterectomy.\n\nExclusion Criteria:\n\nPregnant or breastfeeding at Screening or planning to become pregnant (self or partner) at any time during the study.\nUse of any investigational product or investigational medical device within 30 days prior to Screening, or requirement for any investigational agent prior to completion of all scheduled study assessments.\nIngestion of

of such severity and acuity, in the opinion of the investigator, that it warrants immediate surgical intervention or other treatment or may not allow safe participation in the study.\nHas had any hypersensitivity to SA or its excipients that, in the judgment of the investigator, places the subject at increased risk for adverse effects.\nHas a concurrent disease or condition that, in the view of the principal investigator, places the subject at high risk of poor treatment compliance or of not completing the study, or would interfere with study participation or would affect safety.\nHas
