Level of VY-HTT01 in blood
Zeitfenster: Collected for duration of study, average of 1 year after treatment
|
Change in baseline of the levels of VY-HTT01 vector genome in blood over time.
|
Collected for duration of study, average of 1 year after treatment
|
|
Unified Huntington Disease Rating Scale (UHDRS)
Zeitfenster: Collected for duration of study, average of 1 year after treatment
|
UHDRS will assess changes from baseline in summary scores of motor function, cognitive function, behavioral function, and functional abilities.
UHDRS uses a 5-point ordinal scale ranging from 0-4 with the highest score indicating a more severe (worse) outcome.
|
Collected for duration of study, average of 1 year after treatment
|
|
Clinical Global Impression (CGI) Measures
Zeitfenster: Collected for duration of study, average of 1 year after treatment
|
CGI-Global Improvement measure will assess changes from baseline in CGI-Severity of Illness score.
Both CGI-Global Improvement and CGI- Severity measures are based on a 7-point scale, with the highest score indicating a more severe (worse) outcome.
|
Collected for duration of study, average of 1 year after treatment
|
|
Huntington's Disease Quality of Life (HD-QOL) Measure
Zeitfenster: Collected for duration of study, average of 1 year after treatment
|
HD-QOL measure will assess changes from baseline in the HD-QOL score using a 40-question scale to identify quality of life in HD.
HD-QOL is based on a 7-point scale of frequency ranging from "never" to "all of the time" with "extreme problems" indicating a more severe (worse) outcome.
|
Collected for duration of study, average of 1 year after treatment
|
|
EuroQol 5 Dimension 5 Level (EQ-5D-5L) Measure
Zeitfenster: Collected for duration of study, average of 1 year after treatment
|
EQ-5D-5L measure will assess changes from baseline in the EQ-5D-5L score across 5 domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.
The EQ-5D-5L is scored on a 5-level severity ranking that ranges from "no problems" through "extreme problems", with "extreme problems" indicating a more severe (worse) outcome.

Magnetic Resistance Imagining (MRI)
Zeitfenster: Collected for duration of study, average of 1 year after treatment
|
MRI assessments will include whole brain volume, white matter volume, gray matter volume, and ventricular volume, and volumes of the putamen and thalamus covered by VY-HTT01 infusions during surgery.

Huntington's Disease Cognitive Assessment Battery (HD-CAB) Measure
Zeitfenster: Collected for duration of study, average of 1 year after treatment
|
HD-CAB measure will assess changes from baseline in the HD-CAB score for cognitive dysfunction in early manifest HD patients.
HD-CAB consists of 6 tests; (1) Symbol Digit Modality Test (SDMT), (2) Paced Tapping, (3) One Touch Stockings of Cambridge, (4) Emotional Recognition, (5) Trial Making B and (6) Hopkins Learning Test.
A multi-component score is derived by transforming the subject's score on each cognitive test to a z-score.
The six z-scores are averaged to produce the HD-CAB score.
A positive change from baseline indicates improvement in cognitive function; a negative change indicates worsening in cognitive function.
