Key inclusion & exclusion criteria
|
Inclusion Criteria:
- Male or female, aged = 18 years old
- 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
- Have a documented diagnosis of GNEM, HIBM, distal myopathy with rimmed vacuoles
(DMRV), or Nonaka disease due to previously demonstrated mutations in the gene
encoding the GNE/N-acetylmannosamine kinase (MNK) enzyme (genotyping will not be
conducted in this study).
- Should meet the criteria for severe ambulatory impairment defined below:
- Unable to rise from a seated position to standing without help from another
person, assistive device(s), stationary object, or other support AND
- Unable to walk without the assistance of another person OR if able to walk (use
of assistive device(s) permitted), requires at least 2 minutes to walk 40 meters
(one full lap of the 6-minute walk test [6MWT] course) AND
- Use of wheelchair or scooter for activities outside of the home or unable to
leave the home independently
- 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 salpingo-oophorectomy and are sexually active must
consent to use highly 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 (when this is in line with
the preferred and usual lifestyle of the subject) which means not having sex because
the subject chooses not to), from the period following the signing of the informed
consent through 30 days 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
Exclusion Criteria:
- Ingestion of N-acetyl-D-mannosamine (ManNAc), SA, 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
- Prior participation in a clinical trial involving treatment with Ace-ER/placebo and/or
Sialic Acid immediate release (SA-IR) in the past year
- Has had any hypersensitivity to aceneuramic acid or its excipients that, in the
judgment of the investigator, places the subject at increased risk for adverse effects
- Has serum transaminase (i.e. aspartate aminotransferase [AST] or gamma-glutamyl
transpeptidase [GGT]) levels greater than 3X the upper limit of normal (ULN) for
age/gender, or serum creatinine of greater than 2X ULN at Screening
- 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
