A novel, efficient and seamless Phase 2A‐2B design to test varoglutamstat in early AD: the VIVA‐MIND study

Improved Phase 2 study designs may increase success rates in late stage AD trials. Varoglutamstat (PQ912) is an oral small molecule glutaminyl cyclase inhibitor designed to address several key disease mechanisms. A Phase 2A study (NCT02389413) of 120 early AD patients treated for 12 weeks provided preliminary evidence of safety and tolerability, and effects on working memory, CSF biomarkers, and synaptic function (EEG theta‐power).
