Part 1 Double Blind - Evaluation of Efficacy of AL001 Compared With Placebo as Measured by the CDR® Plus NACC FTLD-SB in Symptomatic Patients
Délai: Through study completion, on average up to 96 weeks
|
Part 1 Primary Endpoint - Change from baseline to Weeks 48, 72, and 96 in the CDR® plus NACC FTLD-SB. The Clinical Dementia Rating Dementia Staging Instrument PLUS National Alzheimer's Disease Coordinating Center frontotemporal lobar degeneration Behavior & Language Domains Sum of Boxes (CDR® plus NACC FTLD-SB) is administered by a healthcare professional and based on individual ratings of the eight domains: memory, orientation, judgment and problem solving, community affairs, home and hobbies, personal care, language and behavior. Impairment is scored on a scale in which none = 0, questionable = 0.5, mild = 1, moderate = 2 and severe = 3. The 8 individual domain ratings, or "box scores", were added together to give the CDR® plus NACC FTLD-SB which ranges from 0-24. Higher score indicates severe impairment. |

Part 1 Double Blind - Evaluation of Efficacy of AL001 Compared With Placebo in Symptomatic Participants as Measured by CGI-S
Délai: Baseline to 96 weeks
|
Change from baseline to Weeks 48, 72, and 96 on the CGI-S. The CGI-S is used by a clinician to rate the severity of a participant's disease relative to the clinician's past experience with patients who have the same disease using an ordinal scale ranging from 1=normal, not at all ill; 2=borderline ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; and 7=among the most extremely ill patients. Higher scores indicate worsening. |

Part 1 Double Blind - Evaluation of Efficacy of AL001 Compared With Placebo in Symptomatic Participants as Measured by CGI-I
Délai: Baseline to 96 weeks
|
Actual values at Weeks 48, 72, and 96 on the CGI-I. The CGI-I is used by a clinician to rate how much a participant's disease has improved or worsened relative to baseline using an ordinal scale ranging from 1=very much improved; 2=much improved; 3=minimally improved; 4=no change from baseline; 5=minimally worse; 6= much worse; and 7=very much worse. Higher scores indicate worsening. |

Part 1 Double Blind - Evaluation of Efficacy of AL001 Compared With Placebo in Symptomatic Participants as Measured by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Score
Délai: Baseline to 96 weeks
|
Change from baseline to Weeks 48, 72, and 96 on the RBANS. RBANS is 20 to 25 minute battery developed for cognitive assessment, detection, and characterization of dementia. RBANS includes 12 subtests that measure following 5 indices: (1)Attention Index, composed of Digit Span and Coding; (2)Language Index, consisting of Picture Naming and Semantic Fluency subtests; (3)Visuospatial/Construction Index, made up of Figure Copy and Line Orientation subtests; (4)Immediate Memory Index, composed of List Learning and Story Memory subtests, and (5)Delayed Memory Index, consisting of List Recall, List Recognition, Story Recall, and Figure Recall subtests. Completion of RBANS yields 5 index scores based on participant performance on various subtests, as well as a composite Total Index score for battery. Total index scores range from 40 to 160, and are normalized to a mean of 100 and standard deviation (SD) of 15. Higher scores indicate less impairment. |

Part 1 Double Blind: Clinical Progression as Measured by Frontotemporal Dementia Rating Scale (FRS) Logit Score in Symptomatic Participants
Délai: baseline to 96 weeks
|
The FRS is a 30-item scale with item responses of 'All the time,' 'Sometimes,' 'Never,' or 'Not applicable' for each item. The total percentage score is calculated as the number of items with a response of 'Never,' divided by the number of applicable items, excluding those marked 'not applicable.' The percentage score ranges from 0 to 100, inclusive, with higher scores indicating better function (fewer behavioral/functional problems) and lower scores indicating worse function. The percentage score is converted to a logit score ranging from -6.66 to 5.39 using a look-up table defined as part of the FRS instrument, where a higher (more positive) logit score indicates better function/less disease severity (5.39 = normal) and a lower (more negative) logit score indicates worse function/greater disease severity (-6.66 = advanced/profound impairment). A decrease in logit score over time reflects clinical progression |
