Objectives

Narrative objectives1

Evaluate the long-term safety and efficacy of 6g/day for SA-ER treatment in GNE myopathy patients with a open-lavel extension study, with the patient who participated in and completed the randomised, double-blind, placebo-controlled phase II/III study of NPC-09 (N-acetylneuraminic acid) (UMIN000020683)

Assessment

Primary outcomes

The amount of change in upper extremity muscle strength composite score (UEC score) between at the time before the start of administration and at the point of last evaluation

Key secondary outcomes

Analyses of secondary efficacy variables will follow the same methods as the primary analyses of the primary endpoint, where data are available.
- GNEM-FAS mobility domain score
- GNEM-FAS upper extremity domain score
- Lower extremity muscle strength composite score (LEC score)
- Sit-to-stand score calculated as the number of times a subject can rise from a sitting to a standing position in a 30-second period
- Weighted arm lift score calculated as the number of times a subject can raise a 1kg weight overhead in a 30-second period
- Muscle strength in the knee extensors: bilateral total force (in kg) and percent predicted using published normative data adjusted for age, gender, and weight
- Walking ability as measured by distance walked in the six-minute walk test (6MWT), which will be reported as distance in meters and percent predicted based on normative data for age and gender

<Tertiary outcomes>
Analyses of tertiary variables will follow the same methods as the primary analyses of the primary endpoint, where data are available.
- UEC score based on percent predicted bilateral strength recorded in the upper extremity muscle groups
- LEC score based on percent predicted bilateral strength recorded in the upper extremity muscle groups
- Muscle strength (total force in kg) for each individual muscle group comprising the UEC and LEC
Percent predicted muscle strength for each individual muscle group comprising the UEC and LEC using published normative data adjusted for age, gender, and weight
- GNEM-FAS total score
- GNEM-FAS self-care domain score
- Health-related quality of life as measured by the Individual Neuromuscular Quality of Life Questionnaire (INQoL)

- Creatine kinase (CK) levels in serum
- Trough (pre-dose) SA levels in serum (free)

Key inclusion criteria

Among the patients who participated in and completed the randomised, double-blined, placebo-controlled phase II/III study of NPC-09 (N-acetylneuraminic acid)(UMIN000020683), the patients who fulfill all the following inclusion and exclusion criteria.

-Willing and able to provide written, signed informed consent after the nature of the study has been explained, and before any research-related procedures are conducted
-Willing and able to comply with all study procedures
-Participants of child-bearing potential or with partners of child-bearing potential who have not undergone a bilateral sapling-oophorectomy and are sexually active must consent to use an effective method of contraception as determined by the site investigator (i.e. oral hormonal contraceptives, patch hormonal contraceptives, vaginal ring, intrauterine device, physical double-barrier methods, surgical hysterectomy, vasectomy, tubal ligation or true abstinence) from the period following the signing of the informed consent through 3 months after last dose of study drug
-Females 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, have had tubal ligation at least one year prior to Screening, or who have had a total hysterectomy or bilateral salpingo-oophorectomy

Key exclusion criteria

-Ingestion of N-acetyl-D-mannosamine (ManNAc), SA (except for IND for the randomised, double-blined, placebo-controlled phase II/III study of NPC-09 (N-acetylneuraminic acid)(UMIN000020683)), or related metabolites; intravenous immunoglobulin (IVIG); or anything that can be metabolized to produce SA in the body within 60 days prior to the Screening Visit
-Has had any hypersensitivity to SA or its excipients that, in the judgment of the investigator, places the subject at increased risk for adverse effects
-Pregnant or breastfeeding at Screening or planning to become pregnant (self or partner) at any time during the study
-Use of any investigational product or investigational medical device within 30 days prior to Screening, or anticipated requirement for any investigational agent prior to completion of all scheduled study assessments
-Has a condition 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
-Has a concurrent disease, active suicidal ideation, or other condition that, in the view of the 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
-More than 400 mL blood donation within 16 weeks
-Presence of alcohol or drug dependency
-Patients whom the investigator judges not to be appropriate for the subject
