|---|---|---|---|
| Primary | PAP: PP: Percent Change From Baseline in CSF GM2 Biomarker to Week 104 | Baseline (Day 1) and Week 104 | Lumbar puncture was performed for obtaining CSF samples at specified timepoints to assess the presence of GM2 biomarker in PP in PAP. The baseline value was defined as the last available value before or equal to the first dose of study drug date in the PAP. |
| Primary | PAP: PP: Annualized Rate of Change From Baseline in the 9-HPT to Week 104 | Baseline (Day 1) and Week 104 | 9-HPT is a test of upper extremity (arm and hand) function.Participant is seated at table with small, shallow container holding pegs and block containing 9 empty holes.On start command when stopwatch is started,participant picks up 9 pegs one at a time as quickly as possible, puts them in 9 holes and once they are in holes, removes them again as quickly as possible one at a time,replacing them into shallow container. Both dominant and non-dominant hands are tested twice (2 consecutive trials of dominant hand followed immediately by 2 consecutive trials of non-dominant hand).Total time (ranging up to 300 seconds):averaged, converted to reciprocals which were averaged and back-transformed to obtain global 9-HPT.Higher value on 9-HPT is indicative of higher disability.Mean annualized rate of change in 9-HPT was obtained from exponential transformation of mean slope of log-transformed 9-HPT.Baseline: last available value before or equal to the first dose of study drug date in the PAP. |

| Secondary | PAP: PP and SP: Change From Baseline in 25-foot Walk Test (25FWT) to Week 104 | Baseline (Day 1) and Week 104 | The 25FWT is a quantitative mobility and leg function performance test based on a timed 25-foot walk. The participant is directed to one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly and safely as possible for 2 trials (can use assistive devices). The time is calculated from the initiation of the instruction to start and ends when the participant has reached the 25-foot mark. The amount of time (in seconds) to walk 25 feet is recorded (ranging up to 180 seconds). The 25FWT score is defined as the average of 2 trials. A higher value on the 25FWT is indicative of higher disability. The baseline value was defined as the last available value before or equal to the first dose of study drug date in the PAP. |
