A study conducted by Pfizer found that GRN-529 reduced repetitive behaviors without sedation and partially increased sociability in mouse models of autism. [2]

Another study conducted by Pfizer found a therapeutically relevant effect in animal models of depression. It is theorized to work by reducing glutamate receptor hyperactivity.[3]
