About this study
Official title: Multi-Reader, Multi-Case, Cross-Over, Retrospective, Superiority, Pivotal Study to Evaluate Effectiveness of Lunit INSIGHT DBT in the Assistance of Detection and Diagnosis of Breast Cancer During 3D Mammography Interpretation
This study aims to evaluate Effectiveness of Lunit INSIGHT DBT in the assistance of detection and diagnosis of breast cancer during 3D mammography interpretation
Read the detailed description
The primary objective of the trial is to evaluate the effectiveness of Lunit INSIGHT DBT in the assistance of detection and diagnosis of breast cancer by comparing the clinical performance of radiologists before and after using Lunit INSIGHT DBT in their DBT reading and secondarily examining the use of Lunit INSIGHT DBT to shorten DBT reading time.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Digital Breast TomosynthesisRadiation
Digital Breast Tomosynthesis (DBT) is a type of 3D mammography that creates detailed images of the breast tissue. It uses X-rays to take multiple images at different angles and combines them to create a clear, layered view of the breast tissue. DBT is used for breast cancer screening and diagnosis and provides a more accurate view of the breast tissue compared to traditional 2D mammography.
| Study group | Role | What they receive |
|---|---|---|
| Cancer group | Interpreted as BI-RADS 0 (Assessment Incomplete), BI-RADS 3 (Probably Benign), 4 (Suspicious) or 5 (Highly Suggestive of Malignancy) with a visible suspicious lesion for breast cancer on the DBT exam and confirmed as a cancer (malignant) through the subsequent biopsy conducted within following 1 year of the DBT exam. Receives: Radiation: Digital Breast Tomosynthesis | |
| Non-Cancer group | Negative Cases
▪ Interpreted as BI-RADS 0 (Assessment Incomplete) or BI-RADS 1 (Negative) with no cancers on the DBT exam and confirmed as BI-RADS 1 (Negative) on the further diagnostic imaging (e.g., MMG, DBT, MRI, CT and Ultrasound) taken at least after 1 year of the DBT exam.
Benign Cases
* Interpreted as BI-RADS 0 (Assessment Incomplete) or BI-RADS 2 (Benign) with a visible lesion on the DBT exam and confirmed as BI-RADS 2 (Benign) on the further diagnostic imaging (e.g., MMG, DBT, MRI, CT and Ultrasound) taken at least after 1 year of the DBT exam without a further breast biopsy.
* Or for the biopsy-proven benign exams, interpreted as BI-RADS 0 (Assessment Incomplete), BI-RADS 3 (Probably Benign), 4 (Suspicious) or 5 (Highly Suggestive of Malignancy) with a visible suspicious lesion for breast cancer on the DBT exam but confirmed as benign through subsequent biopsy conducted within following 1 year of the DBT exam.

Questions about this trial
What is this clinical trial studying?
An observational study of Breast Cancer, run by Lunit Inc. 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 8 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: finished, as of the sponsor's last update on 19 Sep 2024. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Effectiveness of Lunit INSIGHT DBT (time frame: 3 months after the 1st tomosynthesis reading). 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 Sep 2024.
