| Primary | Clinical Impression of Change in Severity (CI-CS) [Fields et al 2021] | (CI-CS comparing Baseline [Day 1] with IB1001 versus the end of 6-weeks treatment with IB1001 [approximately Day 42]) MINUS (CI-CS comparing the end of 6-weeks treatment with IB1001 [approximately Day 42] versus end of 6-weeks post-treatment washout); | The Clinical Impression of Change in Severity assessment will instruct the blinded rater to consider: compared to the first video, how has the severity of their performance on the 9 Hole Peg Test of the Dominant Hand (9HPT-D) or 8 Meter Walk Test (8MWT) changed (improved or worsened) in 6-weeks as observed in the second video? The Clinical Impression of Change in Severity is evaluated on a 7 point Likert scale (+3=significantly improved to -3= significantly worse). Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). Then, the mean change obtained in the post-treatment period was subtracted from the mean change obtained for the treatment with IB1001 period, with a positive value indicating an improvement in the treatment period compared to the post-treatment washout period. |
| Secondary | Key Secondary Endpoint: Individual Components of the CI-CS | Baseline to end of treatment with IB1001 (Parent Study 6-weeks treatment); End of treatment with IB1001 to the end of post 6-week treatment washout. | The Clinical Impression of Change in Severity assessment will instruct the blinded rater to consider: compared to the first video, how has the severity of their performance on the 9 Hole Peg Test of the Dominant Hand (9HPT-D) or 8 Meter Walk Test (8MWT) changed (improved or worsened) in 6-weeks as observed in the second video? The Clinical Impression of Change in Severity is evaluated on a 7 point Likert scale (+3=significantly improved to -3= significantly worse). Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). |
| Secondary | Key Secondary Endpoint: Change in Severity Based on Average CI-S | (CI-S comparing baseline period [average for Visit 1 and 2] and end of treatment period [average for Visit 3 and 4]) minus (change in CI-S between end of treatment period [average for Visit 3 and 4] and end of washout period [average for Visit 5 and 6]). | The Change in Severity assessment will instruct the blinded rater to consider the severity of the patient at each visit. The Clinical Impression of Severity (CI-S)-assessment ranged from +3 ="normal not ill at all" to -3="among the most extremely ill patients ". Change values were calculated for each period, i.e. treatment with IB1001 (change between the baseline period (average for Visit 1 and Visit 2) and end of treatment period (average for Visit 3 and Visit 4)) and post-treatment washout (between end of treatment period (average for Visit 3 and Visit 4) and end of washout period (average for Visit 5 and Visit 6). Then, the mean change in the post-treatment period was subtracted from the mean change in the treatment with IB1001 period. |
| Secondary | Key Secondary Endpoint: CI-CS Score Reclassified on a 3-Point Scale | Baseline to end of treatment with IB1001 (Parent Study 6-weeks treatment); End of treatment with IB1001 to the end of post 6-week treatment washout | The Clinical Impression of Change in Severity assessment will instruct the blinded rater to consider: compared to the first video, how has the severity of their performance on the 9 Hole Peg Test of the Dominant Hand (9HPT-D) or 8 Meter Walk Test (8MWT) changed (improved or worsened) in 6-weeks as observed in the second video? The Clinical Impression of Change in Severity is evaluated on a 7 point Likert scale (+3=significantly improved to -3= significantly worse). CI-CS scores \<0 were reclassified as worsened (-1), CI-CS scores 0 remained classified as not changed (0), and CI-CS scores \>0 were reclassified as improved (+1). When comparing Visit 4 versus Visit 2 and Visit 6 versus Visit 4, CI-CS scores \<0 were reclassified as worsened (-1), CI-CS scores 0 remained classified as not changed (0), and CI-CS scores \>0 were reclassified as improved (+1). |
| Secondary | Key Secondary Endpoint: CI-CS Score for the Non-Primary Anchor Test | CI-CS of the non-primary anchor test was evaluated, comparing the CI-CS of Visit 4 (end of treatment) versus Visit 2 (baseline) and of Visit 6 (end of washout) versus Visit 4 (end of treatment) as done for the primary anchor test. | The Clinical Impression of Change in Severity assessment will instruct the blinded rater to consider: compared to the first video, how has the severity of their performance on the 9 Hole Peg Test of the Dominant Hand (9HPT-D) or 8 Meter Walk Test (8MWT) changed (improved or worsened) in 6-weeks as observed in the second video? The Clinical Impression of Change in Severity is evaluated on a 7 point Likert scale (+3=significantly improved to -3= significantly worse). Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). |
| Secondary | Spinocerebellar Ataxia Functional Index (SCAFI) [Schmitz-Hübsch et al, 2008] | Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). | Spinocerebellar Ataxia Functional Index (SCAFI) is composed of 8 Meter Walk Test, 9-Hole Peg Test of Dominant and Non-Dominant Hand (9HPT-D/9HPT-ND) (the 3 tests are timed assessments; each is done twice and values are averaged; the 8MWT and 9HPT-D and 9HPT-ND values are converted from times to rates, and the results expressed as a composite Z-score of each test relative to baseline) and the PATA rate (counted number how often a patient can repeat the syllables "PATA" within 10 seconds), a measure of speech performance. The scores of these 3 were transformed to Z-scores (=individual's average of both trials to perform the respective task -mean of study population at baseline) / SD of study population at baseline). A Z-score of 0 equates to the population mean at baseline. For all 3, higher Z-scores (above mean) mean better performance. The SCAFI total score was calculated as the arithmetic mean of the non-missing Z-scores for the 3. A higher total score means better performance. |
| Secondary | Scale for Assessment and Rating of Ataxia (SARA) Score [Schmitz-Hübsch Etal, 2006; Subramony, 2007] | Baseline to end of treatment with IB1001 (Parent Study Day 42); End of treatment with IB1001 to the end of post treatment washout | The Scale for Assessment and Rating of Ataxia has 8 items that are related to gait, stance, sitting, speech, finger-chase test, nose-finger test, fast alternating movements, and heel-shin test. The range is 0-40 points, with a lower score representing neurological improvement and a higher score representing neurological worsening. Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). |
| Secondary | EuroQuol- 5 Dimension (EQ-5D) Quality of Life Scale: Visual Analogue Scale (VAS) | Baseline to end of treatment with IB1001 (Parent Study 6-week treatment): observed VAS values at visit 4; End of treatment with IB1001 to the end of post treatment washout: observed VAS values at visit 6. | For posting, health-related quality of life based on the EQ-5D visual analogue scale (VAS) was presented as a secondary endpoint. EQ-5D VAS is a 0-100 scale where patients are asked to indicate their overall health, with a score of 0 indicating worst health and a score of 100indicating best health. |
| Secondary | Modified Disability Rating Scale (mDRS) [Iturriaga et al. 2006] | Baseline to end of treatment with IB1001 (Parent Study 6-weeks treatment); End of treatment with IB1001 to the end of post treatment washout. | Overall neurological status based on six domains (ambulation, manipulation,language, swallowing, seizures and ocular movements). The Modified Disability Rating Scale (mDRS) ranges from 0-24, where 0 is the best neurological status and 24 is the worst. Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)) |
| Secondary | Investigator's Clinical Global Impressions of Change (CGI-c) | Baseline to end of treatment with IB1001 (Parent Study 6-weeks treatment); End of treatment with IB1001 to the end of post treatment washout. | The Clinical Global Impression of Change assessed by the investigator is evaluated on a 7 point Likert scale ranging from 1='very much improved' to 7='very much worse' Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). |
| Secondary | Parent/Caregiver's Clinical Global Impression of Change (CGI-C) | Baseline to end of treatment with IB1001 (Parent Study 6-week treatment); End of treatment with IB1001 to the end of post treatment washout | The Clinical Global Impression of Change assessed by the parent/caregiver is evaluated on a 7 point Likert scale ranging from 1='very much improved' to 7='very much worse'. Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). |
| Secondary | Patient's Clinical Global Impressions (CGI) if Able | Baseline to end of treatment with IB1001 (Parent Study 6-weeks treatment); End of treatment with IB1001 to the end of post treatment washout. | The Clinical Global Impression of Change assessed by the patient (if able) is evaluated on a 7 point Likert scale ranging from 1='very much improved' to 7='very much worse'. Change values were calculated for each period, i.e. treatment with IB1001 (comparing the end of treatment (Visit 4) with baseline (Visit 2)) and post-treatment washout (comparing the end of washout (Visit 6) with the end of treatment (Visit 4)). |
