Each stimulation visit serves as the pre-stimulation baseline for that session, the 1-week post-stimulation measurement for the prior session, and the 2-week post-stimulation measurement for the session before that. A platform-administered scale battery at day 7 after the last stimulation captures the 1-week measurement for the final session; a remote final treatment-period follow-up approximately 2 weeks after the last stimulation captures the 2-week measurement. A remote 3-month post-treatment check-in captures durability and any delayed adverse events.\n\nThe trial uses a two-stage architecture. In Stage 1, visits are allocated across all seven candidate targets. After approximately 300 visits, the Sponsor and ARPA-H convene a joint review and select 3-5 targets for continued Bayesian optimization in Stage 2.\n\nMonitoring during enrollment includes validated clinical scales (PHQ-9, GAD-7, OCI-R) at baseline, before each stimulation visit, at the final treatment-period follow-up, and at the 3-month follow-up; transdiagnostic visual analog scales, a morning sleep diary, and brief voice recordings prompted through the Attune platform during monitoring blocks; optional nightly ambulatory EEG; and a smart watch worn from Visit 0 through device return.
