主要结果指标

结果测量
措施说明
大体时间
Change in Clinical Dementia Rating Scale - Sum of Boxes (CDR-SB) in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)
大体时间:16 weeks

Evaluate the efficacy of neflamapimod, compared to placebo, as a treatment for DLB, as assessed by the CDR-SB scale.

CDR-SB scores range from 0 to 18 with a higher score indicating worsening of cognitive impairment.

16 weeks

次要结果测量

结果测量
措施说明
大体时间
Change in Timed Up and Go Test (TUG) in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)
大体时间:16 weeks

Evaluate if neflamapimod improves motor function in participants with DLB, compared to placebo, as assessed by the TUG test.

TUG scores typically range from 6 to 20 seconds with a higher score indicating worse mobility. A score of >15 indicates an increased risk of falls.

16 weeks
Change in the Composite Score of the Neuropsychological Test Battery (NTB), Including Tests of Attention, Executive Function, and Visual Learning in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)
大体时间:16 weeks

Evaluate if neflamapimod improves cognition, compared to placebo, as assessed by a DLB-specific NTB in participants with DLB. NTB includes Cogstate Detection test (DET), Cogstate Identification test (IDN), Cogstate One Card Learning test (OCL), Cogstate One Back test (ONB).

Each score on the individual tests is converted to a z-score, and then a total z-score for the composite is calculated, in which each test is weighted equally. As the analysis is based on z-scores, there is no minimum or maximum value. A z-score of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. A positive change in z-score indicates an improvement in cognition and a negative change in z-score indicates a worsening in cognition.

16 weeks
Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (ADCS-GCIC) Score at Week 16 in Neflamapimod-treated Participants Compared to Placebo Recipients (Blinded Treatment Period)
大体时间:16 weeks

Evaluate if neflamapimod improves global (cognition, function and behavior) disease status evaluated by a clinician with caregiver input, compared to placebo, in participants with DLB, as assessed ADCS-CGIC score.

ADCS-CGIC scores range from 1 to 7, where 1 = marked improvement, 2= moderate improvement, 3 = minimal improvement, 4 = no change, 5 = minimal worsening, 6 = moderate worsening, and 7 = marked worsening.
