Challenges in Drug Development • Heterogeneity – Within diagnoses – Comorbidities across diagnoses • Need ways to select and stratify patients going into trials

Vision for Precision Psychiatry Research Domain Criteria (RDoC) Key Deliverables • Biotypes to characterize Trans-Diagnostic Research heterogeneity & stratify Framework samples • Mechanisms across units of analysis • Putative therapeutic targets • Quantify target engagement Example: • Targeting Anhedonia Objectively quantifiable domains of transdiagnostically via function , studied across levels of analysis FAST-FAIL from genes to behaviors
FAST-FAIL Approach Develop biomarker reflecting activity of drug at the neurobiological target Use biomarker to select dose that engages target Phase IIa proof of mechanism study with change in brain activity as primary outcome Does engaging the target achieve predicted effect on brain activity? YES NO Proceed to study with Fail the drug (in an clinical endpoint informative way)
FAST-FAIL Approach Biomarker: Kappa opioid receptor – PET ligand Develop biomarker reflecting activity of drug at the neurobiological target Use biomarker to select dose that engages target Selected dose with robust KOR antagonism • Transdiagnostic sample (mood or Phase IIa POM study: inc ventral striatum activation Phase IIa proof of mechanism study with change in anxiety disorder) and Snaith score≥20) during reward anticipation primary outcome brain activity as primary outcome Does engaging the target achieve predicted effect on brain activity? YES NO Proceed to study with Fail the drug (in an Nature Reviews: Drug clinical endpoint informative way) Discovery 2019; 18:82
FAST-FAIL Results Biomarker: Kappa opioid receptor – PET ligand Develop biomarker reflecting activity of drug at the neurobiological target • Met go-criterion on primary outcome: Use biomarker to select dose that engages target Selected dose with robust KOR antagonism inc fMRI ventral striatum activation during reward anticipation Phase IIa POM study: inc ventral striatum activation during reward anticipation primary outcome Does engaging the target achieve predicted effect on brain activity? YES NO Proceed to study with Fail the drug (in an clinical endpoint informative way) Nature Medicine, In Press
