About this study

The goal of this observational study is to learn whether at-home blood biomarker testing for Alzheimer's disease risk is feasible and acceptable in older adults with cognitive concerns. The main questions it aims to answer are:

  • Can older adults with subjective cognitive concerns or possible mild cognitive impairment successfully complete a fully remote workflow that includes at-home capillary blood collection, overnight shipping, central laboratory analysis of phosphorylated tau-217 (p-tau217), and remote disclosure of results by a neurologist?
  • Is this remote at-home p-tau217 testing workflow acceptable to participants? Participants are adults aged 65 and older who participated in the SHUTi MIND parent study (NCT05565833) and report subjective cognitive concerns or screen positive for possible mild cognitive impairment. Participants will collect a small capillary blood sample at home, return the sample to a central laboratory by overnight shipping for p-tau217 analysis, receive their result during a remote visit with a board-certified neurologist, and complete online surveys at baseline, after results disclosure, and 6 months post-disclosure.
Read the detailed description

Alzheimer's disease (AD) and related dementias are among the most urgent public health challenges, with more than six million Americans currently affected. Early detection is critical to improving outcomes, yet diagnosis is often delayed until symptoms interfere with daily functioning and specialty evaluation is obtained. Blood-based biomarkers, particularly phosphorylated tau-217 (p-tau217), represent a transformative advancement, offering accurate, scalable, and minimally invasive alternatives to cerebrospinal fluid assays and PET imaging. However, their feasibility in remote, population-based workflows remains largely untested.

This study will enroll a prospective, remotely recruited cohort of older adults with subjective cognitive concerns or possible mild cognitive impairment to evaluate the clinical and operational feasibility and acceptability of at-home p-tau217 testing. This project targets individuals at elevated risk for dementia progression but without a formal diagnosis.

After consent, participants will complete brief baseline online surveys and receive an at-home blood collection kit. The kit contains a single-use Tasso capillary blood sampling kit, illustrated written and video instructions, prepaid return packaging, and a customer support contact. Participants self-collect capillary blood from the upper arm and return the sample to a CLIA-certified laboratory (Neurogen Biomarking/AccessDx Laboratory) for p-tau217 immunoassay analysis. All results are reviewed by a board-certified neurologist independent of the study team and classified as positive, negative, or intermediate. Negative results are shared via email, and intermediate or positive results include neurologist disclosure of results to the participant via secure videoconference or telephone, explanation of the meaning and limitations of the result, and, when applicable, recommendation and facilitation of referral for confirmatory testing or specialty evaluation.

Participants complete a post-disclosure acceptability survey within 2 weeks of results disclosure, and a follow-up survey at 6 months post-disclosure, to capture downstream specialty evaluation, confirmatory testing, and treatment initiation. The total per-participant duration is ~6-7 months. By operationalizing a fully remote biomarker workflow, the study aims to inform scalable, patient-centered pathways for early AD diagnosis, especially among rural and underserved populations facing geographic, workforce, and cost barriers to specialty dementia care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT07594665
Study groupRoleWhat they receive
Older Adults with Cognitive ConcernsAdults aged 65 years and older who are participants in the SHUTi MIND parent study (IRB-HSR #220077), reside in the United States, and report subjective cognitive concerns or screen positive for possible mild cognitive impairment based on the Telephone Interview for Cognitive Status (TICS). Participants undergo at-home capillary blood collection for plasma p-tau217 testing, remote results disclosure by a board-certified neurologist, and longitudinal online surveys.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Acceptability of remote, at-home p-tau217 workflow

    Participant-reported acceptability of the fully remote at-home p-tau217 testing and disclosure workflow, measured by a standardized post-disclosure acceptability questionnaire assessing perceived ease of use of the Tasso device, comfort with at-home blood collection, satisfaction with remote results disclosure, perceived burden, and willingness to recommend the workflow to others.

    Measured: From enrollment through study completion (~7 months)

  2. End-to-end remote workflow completion rate

    Proportion of enrolled participants who complete each step of the fully remote workflow: kit receipt, at-home capillary blood collection using the blood-collection device, return shipment within the time window required for sample stability, and completion of remote results disclosure by a board-certified neurologist.

    Measured: From enrollment through study completion (~7 months)

An observational study of Mild Cognitive Impairment (MCI) and Alzheimer's Dementia (AD), run by University of Virginia at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 19 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acceptability of remote, at-home p-tau217 workflow (time frame: From enrollment through study completion (~7 months)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2026.
