K0706 用于诊断患有路易体痴呆症的患者
一项随机、双盲、安慰剂对照研究,以评估 K0706 对路易体痴呆 (DLB) 的安全性、耐受性、药代动力学和药效学以及临床结果的影响
本研究评估了使用 K0706 治疗路易体痴呆 (DLB) 的安全性和耐受性。
假设是 K0706 是安全且可耐受的,并且该药物将改变 DLB 中的 CSF 和血浆生物标志物。 还将评估认知、行为和运动功能的临床评估。 总共 45 名参与者将以 1:1:1 的比例随机分为 3 组(每组 n=15),分别接受 192 毫克 K0706 粉末(相当于 96 毫克 K0706 胶囊)或 384 毫克粉末的小袋治疗K0706(相当于 192 粒 K0706 胶囊)或小袋匹配安慰剂(相当于安慰剂胶囊)12 周,然后是 4 周的清除期。

Measurement of Plasma Biomarkers in DLB Patients
大体时间:Baseline, End of Treatment (EOT), and the change between baseline and EOT

Measurement of Biomarker Concentration in CSF
大体时间:Baseline, End of Treatment (EOT) (12 weeks), and the change between baseline and EOT
|
Concentration of DLB related CSF biomarkers, including HVA, DOPAC, Abeta40/42, total tau, ptau231/181 and total and oligomeric alpha-synuclein were measured at Baseline and 12 weeks.

Measurement of Plasma Biomarkers in DLB Patients
大体时间:Baseline, End of Treatment (EOT), and the change between baseline and EOT
|
Ratio of HVA to Dopamine, and Dopamine to HVA in the plasma at Baseline, and 12 weeks The ratio of HVA to DA is a biochemical marker used to measure dopamine turnover, reflecting the rate at which dopamine is synthesized, released, and subsequently broken down in the central nervous system.
High Ratio: Indicates rapid metabolism/degradation of dopamine.
Low Ratio: May suggest lower turnover or reduced activity in dopaminergic pathways.
HVA/DOPAC Ratio (Optimal): 0.1 - 1.8.; a ratio above 1.8 suggests accelerated turnover, typically seen in Parkinson's Disease

Measurement of CSF Biomarkers in DLB Patients
大体时间:Baseline, End of Treatment (EOT) (12 weeks), and the change between baseline and EOT
|
Ratio of DLB related CSF biomarkers, including Abeta42 to Abeta40, phospho-Tau(181) to Abeta42, and phospho-tau181 to Total Tau at Baseline and 12 weeks. Ab42/Ab40 ratio is a biomarker used to assess Alzheimer's disease (AD) risk. A lower ratio indicates a higher likelihood of amyloid plaque accumulation in the brain and AD pathology. The ptau(181)/Ab42 ratio is a clinical biomarker used to identify AD pathology by measuring the balance between tau protein phosphorylation and amyloid-beta accumulation. Higher ratio values typically indicate a higher likelihood of amyloid and tau pathology in the brain. P-tau181 and its ratio to total tau (t-tau) or other amyloid markers are effective indicators of AD pathology. Reference Range/Ratio: A 95% reference interval for the p-tau181/t-tau ratio has been reported as 0.38-6.34, with higher values indicating a higher likelihood of AD pathology. |

Measurement of the Effects of K0706 on Cognition Using the Montreal Cognitive Assessment (MoCA) at Baseline and 12 Weeks
大体时间:Baseline, 12 weeks (EOT), and change between Baseline and End of Treatment (EOT)
|
The MoCA is designed as a rapid screening instrument for mild cognitive dysfunction.
It assesses different cognitive domains, including attention and concentration, executive functions, memory, language, visuo-constructional skills, conceptual thinking, calculations and orientation.
Scores range between 0 and 30 where 30 is the highest score and 0 is the lowest score.

Measurement of the Effects of K0706 on Cognition Using the Trail Making Test (TMT)
大体时间:12 weeks
|
The Trail Making Test (TMT) is a neuropsychological test of visual attention and task switching.
It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy.
The test can provide information about visual search speed, scanning, speed of processing, mental flexibility, as well as executive functioning.
The time to complete the test is measured in seconds.
Lower times indicate better executive function, while higher scores suggest impairment.

Measuring the Effects of K0706 on Behavior Using the Alzheimer's Disease Cooperative Study-Activity of Daily Living Scale.
大体时间:12 weeks
|
ADCS-ADL is an activity of daily living inventory to assess functional performance.
Using a structured interview format, study partners are queried as to whether participants attempted each item in the inventory during the prior 4 weeks and their level of performance.
The ADCS-ADL includes some items from traditional basic ADL tests as well as instrumental (complex) activities of daily living.
It is a 23 item scale that provide a total score from 0-78 with a lower score indicating greater severity; 0 is the minimum score and 78 is the maximum score.

Measuring the Effects of K0706 on Motor Function by Using the Unified Parkinson's Disease Rating Scale (UPDRS)-I-III.
大体时间:12 weeks
|
UPDRS-I-III is used to follow the longitudinal course of Parkinson's disease.
The UPDRS is made up of these sections: Part I: evaluation of mentation, behavior, and mood.
Part II: self-evaluation of the activities of daily life (ADLs) Part III: clinician-scored monitored motor evaluation.
Part IV: complications of therapy.
Part V: Hoehn and Yahr staging of severity of Parkinson's disease.
The minimum possible score on the UPDRS is 0, which indicates no disability or no symptoms of Parkinson's disease.
The scale, used to assess severity, typically ranges from 0 to 199 (total) (199 being the maximum) or 0 to 108 (motor section, Part III) (108 being maximum).
Higher scores on the Unified Parkinson's Disease Rating Scale (UPDRS) Parts I-III indicate increased severity of disease, greater disability, and more significant impairment, while lower scores signify better function.

Measuring the Effects of K0706 on Motor Function by Using the Timed-Up-And-Go (TUG).
大体时间:12 weeks
|
Timed Up and Go (TUG) is an assessment of mobility, balance, walking ability, and fall risk.
It measures the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down.
This assessment is measured in seconds.
A score of less than 10 seconds is normal, 14-20 seconds indicates a high fall risk or frailty, and over 30 seconds suggests significant mobility impairment.
