Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious TEAEs, Discontinuations Due to TEAEs, and Deaths
Query!
Assessment method [1]
0
0
An adverse event (AE) was defined as any untoward medical occurrence, whether or not considered drug related. Serious adverse events (SAEs) are AEs that at any dose, in the view of either the investigator or sponsor, 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; a congenital anomaly/birth defect; other important medical event. An AE was considered a TEAE if it occurred on or after the first dose in this study, and was not present prior to the first dose in this study, or it was present at the first dose in this study but increased in severity during the study. Severity was based on Common Terminology Criteria for Adverse Events (CTCAE): 1 = mild, 2 = moderate, 3 = severe, 4 = life threatening, and 5 = death related to AE.

Change From Baseline Over Time in CNS Total Score
Query!
Assessment method [2]
0
0
The CNS evaluates measures of neurological function and development delay, and is the sum of scores for the following domains: Weight, Height, Head Circumference, General Medical Exam, Funduscopic Exam, Cranial Nerves, Stance & Gait, Involuntary Movements, Sensation, Cerebellar Function, Muscle Bulk, Tone & Strength, Myotatic Reflexes, Toe Sign, Other Findings. The CNS is only scored when all domains are measured and ranges from 0 (abnormal exam) to 76 (normal exam). Higher scores are associated with higher neurological function.

Change From Baseline Over Time in SF-10 Health Survey for Children Physical Summary Score
Query!
Assessment method [3]
0
0
The SF-10 Health Survey for Children was administered to caregivers of participants aged 5-17 years. Responses are used to generate 2 component summary scores: Physical Summary Score and the Psychosocial Summary Score. The T-score based scale scores were centered so that a score of 50 corresponds to the average score in a comprehensive 2006 sample (a combination of general population and supplemental disability and chronic condition samples). Higher scores are associated with better quality of life.

Change From Baseline Over Time in SF-12v2 Health Survey PCS Score
Query!
Assessment method [5]
0
0
SF-12v2 was assessed for adults 18 years of age and older. Eight domain scores were used to generate 2 component summary scores: physical health (PCS) and mental health (MCS). The PCS and MCS scores have mean of 50 and SD of 10. The T-score based scoring method scores the data in relation to U.S. general population T-scores. Therefore, all scores obtained that are below 50 can be interpreted as below the U.S. general population T-score and scores above 50 can be interpreted as above the U.S. general population T-score. Higher global scores are associated with better quality of life.

Eligibility
Key inclusion criteria

erythrocyte 3-O-methyl-D-glucose uptake assay, or solute carrier family 2 member 1
(SLC2A1) molecular genetic testing (Information obtained from Medical Records)
- Males and females aged at least 1 year old at the time of informed consent
- Completion of UX007G-CL201 study (NCT01993186). Glut1 DS patients who received
UX007/triheptanoin treatment as apart of clinical studies, ISTs or expanded
access/compassionate use treatment programs may be eligible at the discretion of the
Sponsor
- Provide written informed consent or verbal assent (if possible) with written informed
consent by a legally authorized representative after the nature of the study has been
explained, and prior to any research related procedures
- Must, in the opinion of the investigator, be willing and able to complete all aspects
of the study, and comply with accurate completion of the seizure diary
- Females of childbearing potential must have a negative urine pregnancy test at
Baseline and be willing to have additional pregnancy tests during the study. Females
considered not of childbearing potential include those who have not experienced
menarche, are post-menopausal (defined as having no menses for at least 12 months
without an alternative medical cause), or are permanently sterile due to total
hysterectomy, bilateral salpingectomy, or bilateral oophorectomy.
- Participants of child-bearing potential or fertile males with partners of
child-bearing potential who are sexually active must consent to use a highly-effective
method of contraception as determined by the investigator from the period following
the signing of the informed consent through 30 days after last dose of study drug.

Key exclusion criteria
- Any known hypersensitivity to triheptanoin, that in the judgement of the investigator,
places the subject at an increased risk for adverse effects
- History of, or current suicidal ideation, behavior and/or attempts
- Pregnant and/or breast feeding an infant
- Unwilling or unable to discontinue use of prohibited medication (barbiturates,
pancreatic lipase inhibitors) or other substance that may confound study objectives.
Use of up to 3 concomitant antiepileptic drugs is allowed, provided dose has been
stable at least 14 days prior to Baseline
- Use of any Investigational Product, drug or supplement (other than UX007) within 30
days prior to Baseline, or at any time during the study
- Has a condition of such severity and acuity, in the opinion of the investigator, that
it warrants immediate surgical intervention or other treatment
- Has a concurrent disease or condition, or laboratory abnormality 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 introduce
additional safety concerns
