Trial summary

The primary objective of the study is to evaluate whether a set of algorithms analysing acoustic and linguistic patterns of speech, can predict change in PACC5 between baseline and +12 month follow up across all four Arms, as measured by the coefficient of individual agreement (CIA) between the change in PACC5 and the… Read more about this study

About this study

Official title: A Study to Evaluate the Ability of Speech- and Language-based Digital Biomarkers to Detect and Characterise Prodromal and Preclinical Alzheimer's Disease in a Clinical Setting - FUTURE Extension Study.

The primary objective of the study is to evaluate whether a set of algorithms analysing acoustic and linguistic patterns of speech, can predict change in PACC5 between baseline and +12 month follow up across all four Arms, as measured by the coefficient of individual agreement (CIA) between the change in PACC5 and the corresponding regression model, trained on baseline speech data to predict it. Secondary objectives include (1) evaluating whether similar algorithms can predict change in PACC5 between baseline and +12 month follow up in the cognitively normal (CN) and MCI populations separately; (2) evaluating whether similar algorithms trained to regress against PACC5 scores at baseline, still regress significantly against PACC5 scores at +12 month follow-up, as measured by the coefficient of individual agreement (CIA) between the PACC5 composite at +12 months and the regression model, trained on baseline speech data to predict PACC5 scores at baseline; (3) evaluating whether similar algorithms can classify converters vs non-converters in the cognitively normal Arms (Arm 3 + 4), and fast vs slow decliners in the MCI Arms (Arm 1 + 2), as measured by the AUC, sensitivity, specificity and Cohen's kappa of the corresponding binary classifiers. Secondary objectives include the objectives above, but using time points of +24 months and +36 months; and finally to evaluate whether the model performance for the objectives and outcomes above improved if the model has access to speech data at 1 week, 1 month, and 3 month timepoints.

What is being measured

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

  1. The agreement between the change in the PACC5 composite between baseline and +12 months and the corresponding regression model, trained on baseline speech data, predicting in all four Arms, as measured by the coefficient of individual agreement (CIA).

    Baseline speech data is speech data collected during the first 14 days of the study for each participant.

    Measured: 1 year

Secondary outcomes (8)
  1. The agreement between changes in the PACC5 composite between baseline and +24, +36 months and the corresponding regression models, trained on baseline speech data, predicting in all 4 Arms, as measured by the coefficient of individual agreement (CIA).

    Measured: 3 years

  2. The agreement between the changes in the PACC5 composite between baseline and +12, +24, +36 months and the corresponding regression models, trained on baseline speech data, to predict them in the CN Arms (3 and 4), as measured by the CIA.

    Measured: 3 years

  3. The agreement between the changes in the PACC5 composite between baseline and +12, +24, +36 months and the corresponding regression models, trained on baseline speech data, predicting them in the MCI Arms (Arms 1 and 2), as measured by the CIA.

    Measured: 3 years

  4. The agreement between the PACC5 composite at +12, +24, +36 months and the corresponding regression models, trained on baseline speech data, predicting in all four Arms based on +12, +24, +36 month speech data, as measured by the CIA.

    Measured: 3 years

  5. The agreement between the PACC5 composite at +12, +24, +36 months and the corresponding regression models, trained on baseline speech data and +12, +24, +36 month speech data, as measured by the coefficient of individual agreement (CIA).

    Measured: 3 years

  6. The AUC, sensitivity, specificity and Cohen's kappa of the binary classifier distinguishing between converters vs non-converters in the cognitively normal (CN) Arms (Arms 3 and 4).

    Converters defined as having a CDR Global score of 0.5 or more at +12, +24, +36 months.

    Measured: 3 years

  7. The AUC, sensitivity, specificity and Cohen's kappa of the binary classifier distinguishing between fast decliners vs slow decliners in the MCI Arms (Arms 1 and 2) at +12, +24, +36 months.

    Measured: 3 years

  8. The outcomes above where the model has access to speech data at 1 month, 3 month time points, in addition to baseline speech data.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Alzheimer Disease and Preclinical Alzheimer's Disease, run by Novoic Limited at 4 sites in United Kingdom.

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 3 inclusion and 1 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: stopped early, as of the sponsor's last update on 14 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United Kingdom. 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?

The study was stopped early (reason given: Study only continued to 2 year follow-up.). Results are not available in the source record.

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?

The agreement between the change in the PACC5 composite between baseline and +12 months and the corresponding regression model, trained on baseline speech data, predicting in all four Arms, as measured by the coefficient of individual agreement (CIA). (time frame: 1 year). 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 14 Jun 2024.
