What the grant funds
This Notice of Funding Opportunity (NOFO) uses a R61/R33 Phased Innovation Award activity code to support clinical research applications that are exploratory and developmental in nature and focus on understanding the neurobiological mechanisms underlying SUD, including fundamental brain function relevant to substance use. This NOFO is particularly designed to support exploratory/developmental projects requiring budgets that would exceed that allowed for the R21 mechanism (Neuroscience Research on Drug Abuse (R21 Clinical Trial Optional).
