SAGE‐718 in Patients With Mild Cognitive Impairment or Mild Dementia due to Alzheimer’s Disease: Results From the Phase 2 LUMINARY Study
Bibliographic record
Abstract
Abstract Background Cognitive impairment has a deleterious impact on patients with AD and their caregivers; new therapies are needed. SAGE‐718, a novel N‐methyl‐D‐aspartate receptor positive allosteric modulator, is being investigated for the treatment of cognitive impairment in patients with neurodegenerative diseases such as Alzheimer’s disease (AD). The LUMINARY Study is designed to evaluate the safety/tolerability of SAGE‐718 and its effects on cognitive symptoms in patients with AD. Method LUMINARY (NCT04602624) is an open‐label, Phase 2 study evaluating SAGE‐718 (3mg QD for 14 days) in patients with AD. Patients (aged 50‐80 years) with Montreal Cognitive Assessment (MoCA) scores of 15‐24 were included. Treatment‐emergent adverse event (TEAE) incidence through Day 28 (primary endpoint), other safety outcomes (secondary endpoints), and cognitive and functional assessments were analyzed. Result Twenty‐six patients (69.2% female; mean age 67 years), with a mean±SD MoCA of 20.7±2.61 were enrolled. Most patients (23/26) had a global Clinical Dementia Rating score of 0.5. Eight TEAEs were reported in 7 (26.9%) patients; all were mild/moderate; 6 were treatment related. No serious adverse events or deaths were reported. At Day 14, improvements from baseline were observed on multiple tests of executive functioning (Digit Symbol Substitution, Multitasking, One Touch Stockings, Spatial Working Memory, and 2‐Back tests) and learning and memory (Pattern Recognition Memory and Verbal Recognition Memory tests). Statistically significant MoCA improvement (+2.3 points vs baseline) was observed at Day 28. No changes in attention/psychomotor speed were observed. Functional assessments also captured notable improvement in some patients (Clinical Global Impressions Scales and Amsterdam Instrumental Activities of Daily Living Questionnaire), particularly on items measuring aspects of complex/higher order activities. Conclusion In this study, SAGE‐718 was generally well tolerated and associated with cognitive and functional improvements in patients with AD. These results support further investigation of SAGE‐718 for the treatment of cognitive impairment associated with AD and other neurodegenerative diseases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
