简要总结
Glutamate is fundamentally involved in learning and memory. Memory loss associated with mild cognitive impairment may be due to loss of glutamate receptors in the aging brain. There is evidence CX516 enhances brain activity by specifically targeting remaining glutamate receptors in the affected portions of the brain. This study will test the safety and efficacy of CX516 in the symptomatic treatment of participants with mild cognitive impairment.

结局指标
主要结局
15-Item Word List Delayed Recall
时间窗: 28 Days
The 15-Item Word List delayed recall score is used as a clinical measure of episodic memory, and was the primary outcome variable for this study. Episodic memory of the type addressed by delayed recall of lists and stories (i.e., in the WMS-R logical memory tests and 15-item World List recall tests) is among the earliest deficits during aging and MCI compared to other aspects of cognition (attention, reaction time, language, etc). It was decided to use the 15-item Word List delayed recall test as the primary outcome measure due to its sensitivity in the assessment of MCI. The possible score range for the 15-item Word List Delayed Recall test is 0 to 15. A clinical improvement of MCI or dementia would be characterized by an increase in the score due to an increase in the number of words recalled.
