Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Glass slides are screened for the known features and will be considered eligible for the study only if all of the following criteria apply:
  • Slides are selected from cases in a consecutive manner starting with cases at least 1 year old since accessioning
  • Slide is a glass cover-slipped surgical pathology slide of human tissue
  • Slide is stained with hematoxylin and eosin (H\&E) or other stains
  • Slide has the designated primary feature in the FOV, which is readily observable in its natural environment although the slide may also have one or more secondary features from the same magnification group in the FOV.
  • Slide is available in the archives for use, or purchased commercially, is not damaged, has tissue on the slide which is still in good condition, has a stain that is not faded and otherwise passes all quality checks

Who cannot join

  • Slides are to be excluded from the study if any of the following criteria apply:
  • Slide is unable to be scanned, contains damaged tissue or has indelible markings
  • Slide comes from an active (less than 1 year old) case
  • Slide is from a patient who already has a slide enrolled in the study, only 1 slide per patient to be enrolled

About this study

Official title: Clinical Validation for Feature Detection Precision by WSI Using Hamamatsu NanoZoomer S360MD Digital Slide Scanner System

The objective of this study is to evaluate the repeatability and reproducibility of detection of histological features using whole slide imaging

Read the detailed description

The study will be conducted under the following 3 sub-studies:

  1. Scans within Scanner (Intra-scanner precision substudy),
  2. Scanners within a site (Inter-scanner precision substudy),
  3. Scanners between sites (Inter-site precision substudy)

What is being measured

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

  1. Overall Percentage Agreement of Repeatability and Reproducibility Within Scanner, Between Scanners, and Sites.

    Repeatability and reproducibility of WSI were evaluated using the Average Positive Agreement Rate. Using a comparison of two reads with four possible outcomes (a=both reads detect the feature; b=read 1 fails to detect the feature; c=read 2 fails to detect the feature; d=both reads fail to detect the feature), APA = 2a/(2a+b+c). APA was used to assess outcomes in the following substudies:

    1. Scans within scanner (Intra-scanner Precision): Scans are repeated within the scanner at the site.
    2. Scanners within site (Inter-scanner Precision): Scans are repeated among the scanners at the site
    3. Scans between Sites (Inter-site Precision): Scans are repeated within the scanner at the different sites.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Hamamatsu NanoZoomer S360MD Digital Slide Scanner System in people with Pathology, run by Hamamatsu Photonics K.K. at 3 sites 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 6 inclusion and 4 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: finished, as of the sponsor's last update on 22 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

Yes. Results are posted in the registry (first posted 22 Dec 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Overall Percentage Agreement of Repeatability and Reproducibility Within Scanner, Between Scanners, and Sites. (time frame: 1 day). 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 22 Dec 2022.
