Participant Flow
Recruitment Details | Study enrolled pediatric, adolescent, and adult glucose transporter type 1 deficiency syndrome (Glut1 DS) participants who completed the UX007G-CL201 study (NCT01993186; rollover participants). No non-rollover participants (those from other clinical studies, investigator sponsored trials, or expanded access/compassionate use treatment) enrolled. |
Pre-assignment Details | For continuing UX007G-CL201 participants, the Week 52 visit of that study may have been conducted in conjunction with the Baseline visit for this study to avoid duplication of assessments. |

Overall Seizure Frequency Per 4 Weeks
[1] Mean (Standard Deviation) Unit of measure: Seizures per 4 weeks |
||
Number Analyzed | 15 participants | |
312.17 (528.057) | ||
[1]
Measure Description: The number of observable seizures were recorded by the subject or caregiver via diary. Observable seizures were defined as: generalized tonic-clonic; generalized tonic; generalized clonic; generalized atonic; partial/focal with secondary generalization; myoclonic, myoclonic (astatic) atonic, myoclonic tonic; complex partial/focal; simple partial/focal motor; absence.

Baseline (NCT01993186) Columbia Neurological Score (CNS) Total Score
[1] [2] Mean (Standard Deviation) Unit of measure: Score on a scale |
||
Number Analyzed | 12 participants | |
38.63 (25.428) | ||
[1]
Measure Description: 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.

Baseline (NCT01993186) Short Form (SF) 10 (SF-10) Health Survey for Children Physical Summary Score
[1] [2] Mean (Standard Deviation) Unit of measure: T-score |
||
Number Analyzed | 10 participants | |
32.63 (17.027) | ||
[1]
Measure Description: 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.

Baseline (NCT01993186) SF12 Version 2 (SF-12v2) Health Survey Physical Component Summary (PCS) Score
[1] [2] Mean (Standard Deviation) Unit of measure: T-score |
||
Number Analyzed | 2 participants | |
39.37 (0.523) | ||
[1]
Measure Description: SF-12v2 was assessed for adults aged >=18 years. 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 US general population T-scores. Therefore, all scores obtained that are < 50 can be interpreted as below the US general population T-score and scores > 50 can be interpreted as above the US general population T-score. Higher global scores are associated with better quality of life.
