Focused Ultrasound for Behavioral Health (VANTUS)
Bayesian-Optimized Dose-Finding of ATTN201 Focused Ultrasound for Behavioral Health
This is a double-blind, within-participant crossover, multi-site dose-finding study evaluating the safety, feasibility, and preliminary efficacy of repeated low-intensity focused ultrasound (LIFU) stimulation using the ATTN201 device across seven candidate deep-brain targets in adults with subsyndromal-to-moderate depression, anxiety, or obsessive-compulsive disorder. Every session delivers active ATTN201 stimulation; there is no sham or placebo condition. Participants and the on-site study staff who deliver stimulation and administer the clinical scales are blinded to the brain target and to the stimulation parameters assigned for each session by a constrained Bayesian optimization algorithm.

Szczegółowy opis
Following a remote pre-screen and an in-person screening/baseline visit (Visit 0), at which informed consent is obtained, eligibility is confirmed, baseline clinical scales are administered, optional biospecimens are collected from participants who consent to them, a multi-sequence brain MRI is acquired for targeting, and monitoring devices are fitted, each participant receives between 3 and 10 ATTN201 stimulation sessions spaced approximately 7 days apart. 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.
The 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.
Monitoring 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. All scheduled platform prompts are voluntary at the individual-prompt level.
Blinding: A single on-site research associate positions the device, runs the stimulation session, and administers participant-facing assessments, and is blinded to the brain target and parameter combination; this individual occupies both the care provider and the outcomes assessor role. The stimulation condition is selected by the Bayesian optimization algorithm and pushed to the device as a sealed session. The Lead Principal Investigator and the optimization team are unblinded as required to operate the adaptive design and do not deliver stimulation or administer participant-facing assessments. The independent Medical Monitors and the Data Safety and Monitoring Board receive unblinded safety data.

Opis planu IPD
De-identified individual participant data will be deposited into the ARPA-H designated data repository as required by the funded ARPA-H EVIDENT program. Deposited data include clinical outcome measures (PHQ-9, GAD-7, OCI-R, PROMIS Sleep Disturbance 8a, PROMIS Sleep-Related Impairment 8a, DASS-8, Brief Resilience Scale, Flourishing Scale, and transdiagnostic visual analog scales), delivered stimulation parameters, EEG-derived and wearable-derived biomarker measures, platform-derived measures, relevant metadata, and optional baseline dried blood spot and saliva biospecimens where collected. Participant identifiers are not included in deposited datasets.
Ramy czasowe udostępniania IPD
Deposits occur on rolling quarterly delivery cycles beginning after enrollment of the first participant and continuing through study completion. Deposited data remain available thereafter under the retention terms of the ARPA-H designated data repository.
Kryteria dostępu do udostępniania IPD
Access is governed by the data access procedures of the ARPA-H designated data repository. Requests for deposited data are made to the repository rather than to the sponsor.
