Non-Abstinence Outcomes in Methamphetamine Use Disorder

Reduced drug use is a clinically meaningful target for treatment development, but few studies have evaluated the positive impacts produced by this behavioral change, preventing adoption of this endpoint in clinical trials. The proposed research will fill that critical knowledge gap by demonstrating the biopsychosocial benefits of reduced methamphetamine use. These data will be used to change current accepted methamphetamine treatment endpoints and accelerate identification of therapies for methamphetamine use disorder.

Suvorexant and Alcohol

This research will translate findings from preclinical research and provide the initial clinical evidence that orexin antagonism reduces motivation for alcohol, as well as other alcohol-associated maladaptive behaviors in people with Alcohol Use Disorder. This study will also provide basic science information about the orexinergic mechanisms underlying the pharmacodynamic effects of alcohol in humans. As such, the outcomes will contribute to our understanding of the clinical neurobiology of Alcohol Use Disorder. Overall, the proposed work seeks to expand the scope of current clinical neuroscience research on alcohol addiction by focusing on orexin, which has strong preclinical evidence supporting its critical role in addiction but remains unstudied in humans.
