|---|---|---|---|
| Primary | Change From Baseline in the Niemann-Pick Disease Type C (NPC) Disease Severity Assessed Based on the 5-domain NPCCSS Total Scores | Baseline to Month 12 | NPC disease severity was assessed based on the 5-domain NPC Clinical Severity Scale (NPCCSS). The 5-domain NPCCSS focuses on domains identified by participants, caregivers, and NPC experts as the most clinically relevant when assessing disease progression in NPC: Ambulation, fine motor skills, swallow, cognition, and speech. The scale is derived from the original 17-domain NPCCSS. Each domain is rated on a scale of 0-5 based on clinical assessments, observations, and interviews with participants/caregiver. The total score is a sum of the score of each of the 5 domains and ranges from 0-25, with a higher score indicating more severe clinical impairment. |
| Secondary | Percentage of Responders in Clinical Global Impression Scale of Improvement (CGI-I) - Defined as Percentage of Participants Where the CGI-I Score Remains Stable or Shows Improvement (This Outcome Measure Was Considered Co-primary by the FDA) | Month 12 | The CGI-I is a 7-point scale that rates total improvement of participant's condition. The clinician rates the participants from 1=Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, or 7=Very much worse. Scores thus range from 1-7 with lower scores indicating greater improvement. Responders were the participants with a score of 1 or 2 at Month 12. |
| Secondary | Percentage of Responders in 5-domain NPCCSS - Defined as Participants Where the 5-domain NPCCSS Score Remains Stable or Improves as Compared to Baseline | Baseline to Month 12 | NPC disease severity was assessed based on the 5-domain NPC Clinical Severity Scale (NPCCSS). The 5-domain NPCCSS focuses on domains identified by participants, caregivers, and NPC experts as the most clinically relevant when assessing disease progression in NPC: Ambulation, fine motor skills, swallow, cognition, and speech. The scale is derived from the original 17-domain NPCCSS. Each domain is rated on a scale of 0-5 based on clinical assessments, observations, and interviews with participants/caregiver. The total score is a sum of the score of each of the 5 domains and ranges from 0-25, with a higher score indicating more severe clinical impairment. Stable was defined as a participant's total score for the 5 domains being the same at month 12 as at baseline. Improvement was defined as a participant's total score at month 12 being lower than at baseline. |
| Secondary | Time to Worsening | Baseline to Month 12 | Time to worsening was defined as the time until the participant reached the predefined minimal clinically important difference (MCID) of 2 points compared to baseline on the 5-domain NPC Clinical Severity Scale (NPCCSS). The 5-domain NPCCSS focuses on domains identified by participants, caregivers, and NPC experts as the most clinically relevant when assessing disease progression in NPC: Ambulation, fine motor skills, swallow, cognition, and speech. The scale is derived from the original 17-domain NPCCSS. Each domain is rated on a scale of 0-5 based on clinical assessments, observations, and interviews with participants/caregiver. The total score is a sum of the score of each of the 5 domains and ranges from 0-25, with a higher score indicating more severe clinical impairment. The values reported per group are the 25th percentile Kaplan-Meier estimates and 95% confidence interval. |
| Secondary | Percentage of Participants With Worsening | Months 6 and 12 | Worsening was defined as participants that have reached the predefined MCID of 2 points on their 5-domain NPC Clinical Severity Scale (NPCCSS). The 5-domain NPCCSS focuses on domains identified by participants, caregivers, and NPC experts as the most clinically relevant when assessing disease progression in NPC: Ambulation, fine motor skills, swallow, cognition, and speech. The scale is derived from the original 17-domain NPCCSS. Each domain is rated on a scale of 0-5 based on clinical assessments, observations, and interviews with participants/caregiver. The total score is a sum of the score of each of the 5 domains and ranges from 0-25, with a higher score indicating more severe clinical impairment. |
| Secondary | Change From Baseline in 17-domain NPCCSS Apart From Hearing Domains (i.e. Hearing and Auditory Brainstem Response) | Baseline to 6 and 12 months | The NPC Clinical Severity Scale (NPCCSS) is a disease-specific, clinician-reported outcome measure developed to characterize and quantify NPC disease progression. The 17-domain NPCCSS includes clinical signs and symptoms in nine major and eight minor domains, which are rated on scales of 0-5 (for the major domains) or 0-2 (for the minor domains). The total score is the sum of the score of each of the 17 domains and ranges from 0 to 61, with a high score indicating a more severe clinical impairment. |
| Secondary | Change From Baseline in 5-domain NPCCSS Score | Baseline to 6 months | The 5-domain NPC Clinical Severity Scale (NPCCSS) focuses on domains identified by participants, caregivers, and NPC experts as the most clinically relevant when assessing disease progression in NPC: Ambulation, fine motor skills, swallow, cognition, and speech. The scale is derived from the original 17-domain NPCCSS. Each domain is rated on a scale of 0-5 based on clinical assessments, observations, and interviews with participants/caregiver. The total score is a sum of the score of each of the 5 domains and ranges from 0-25, with a higher score indicating more severe clinical impairment. |
| Secondary | Changes From Baseline in Each Individual Domain of the NPCCSS | Baseline to 6 and 12 months | The NPC Clinical Severity Scale (NPCCSS) is a disease-specific, clinician-reported outcome measure developed to characterize and quantify disease progression. The 17-domain NPCCSS includes clinical signs and symptoms in nine major (ambulation, cognition, eye movement, fine motor, hearing, memory, seizures, speech, swallowing,) and eight minor (auditory brainstem response, behavior, gelastic cataplexy, hyperreflexia, incontinence, narcolepsy, psychiatric, respiratory problems) domains, which are rated on scales of 0-5 (for the major domains) or 0-2 (for the minor domains). A higher score indicates a more severe clinical impairment. |
| Secondary | Change From Baseline in the NPC Clinical Database (NPC-CDB) Score (Modified "Stampfer Score") | Baseline to 6 and 12 months | The NPC Clinical Database (NPC-cdb) score aims to reflect the current clinical status of the participant. The NPC-cdb score represents both historical symptoms and a current status. The test consists of ten areas: visceral signs, development, motor function, ocular-motor abnormalities, seizures/cataplexy/narcolepsy, cognitive abilities and memory, behavioral and psychiatric abnormalities, speech, hearing, and abilities in daily life. The current status score is a severity-weighted sum of 72 symptoms considered as disease-relevant at the time of assessment. Each symptom contributes with a score between 1 and 5, the maximum score is 125. An increase in score reflects a reduction in the participant's abilities. |
| Secondary | Percentage of Participants With Change From Baseline in Quality of Life (EQ-5D-Y) | Baseline to 6 and 12 months | The EQ-5D-Y descriptive system includes 5 descriptive items: Mobility, self-care, doing usual activities, having pain or discomfort, and feeling anxiety or depressed. Each dimension has 3 levels: No problems, some problems, and a lot of problems. The change in the 5 individual items of the EQ-5D-Y per participant was explored by using the pareto principle at 6 and 12 months to show the number (%) of participants who felt: * Better (better on at least one dimension and no worse in any other dimension), * Worse (worse in at least one dimension, and no better in any other dimension) |
| Secondary | Change From Baseline in the Scale for Assessment and Rating of Ataxia (SARA) Score | Baseline to 6 and 12 months | The SARA included eight items reflecting neurologic manifestations of cerebellar ataxia. The test provides a direct and simple description of motor function in a participant. The test consists of 8 test items: gait, stance, sitting, speech disturbance, finger chase, nose-finger test, fast alternating hand movements, and heel-shin slide. The total score of the 8 items ranges from 0 (normal cerebellar function) to 40 (not able to perform any of the test items). |
| Secondary | Change From Baseline in the Time Spent to Complete the Nine-Hole Peg Test (9HPT) | Baseline to 6 and 12 months | The 9HPT test is a direct and simple measurement of fine motor coordination function, eye/hand coordination, and the ability to follow a simple direction. The 9HPT is a timed test in which nine pegs are inserted and removed from nine holes in the pegboard. Both hands are tested starting with the dominant hand. The time spent in completing the 9 HPT using each hand was recorded. |
| Secondary | Percentage of Participants Within Each Severity Category of the Clinical Global Impression Scale of Severity (CGI-S) | Months 6 and 12 | The CGI-S is a 7-point scale that requires the clinician to rate the severity of the participant's illness at the time of assessment. A rating of 1 is considered normal, or with the least severe symptoms, a rating of 7 is extremely ill, or the worst symptoms. Scores thus range from 1-7 with lower scores indicating less severe disease. |
| Secondary | Percentage of Participants Within Each Category of the Clinical Global Impression Scale of Improvement (CGI-I) | Months 6 and 12 | The CGI-I is a 7-point scale that rates total improvement of participant's condition. The clinician rates the participants from 1=Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, or 7=Very much worse. Scores thus range from 1-7 with lower scores indicating greater improvement. |
