D-serine Augmentation of Neuroplasticity Based Auditory Learning in Schizophrenia
In Brief
A Phase 2 clinical trial evaluating D-serine and Placebo for Schizophrenia and Schizo Affective Disorder. Completed, enrolled 45 participants across 2 sites.
Detailed Summary
Schizophrenia is a major public health problem associated with cognitive deficits, such as short and long term memory, executive functioning, attention and speed of processing that are amongst the strongest predictors of impaired functional outcome. In addition, schizophrenia patients show reduced "plasticity", defined as reduced learning. D-serine is a naturally occurring activator of the N-methyl-d-aspartate-type glutamate receptors (NMDAR) in the brain, and this project will assess the optimal dose of D-serine treatment over three sessions of a program designed to measure auditory plasticity.

Timeline
Interventions
Subjects will receive three sessions of auditory remediation paired with either D-serine or Placebo in a 4:1 D-serine:placebo ratio. This will be conducted in 3 separate cohorts of D-serine dose 80, 100 and 120 mg/kg, which 15 subjects per cohort (12 active and 3 placebo) per cohort
