Early-Stage Breast Carcinoma | Device: Cyrcadia CBR™ device placement for abnormality screening | Phase 1 Phase 2 |
The Cyrcadia CBR™ (Circadian Biometric Recorder) includes wearable biometric patches and a detachable data recording device. The CBR™ records chronobiologic data while the patient is totally ambulatory and going about her normal daily routine. Following removal of the detachable data recording device from the wearable biometric patches, the data is transferred to a computer for analysis. The Cyrcadia CBR™ will be placed on the patient for the duration of 2 to 24 hours. There is no restriction of daily activity. The study subject is requested to sponge bathe rather than shower while wearing the device, keeping the device dry during the testing procedure. After this period, the CBR™ will be removed and the data will be transferred to a computer for analysis.
The primary endpoint of this 173 patient study is to determine the accuracy of Cyrcadia CBR™ as a supplemental screening device to mammography and ultrasound in predicting a diagnosis of breast cancer. Specific emphasis will be on the utilization of the CBR as a secondary screening device to reduce the number of biopsies currently performed on non-cancerous tissue. A secondary emphasis will be on the CBR to act as an improved screening solution over mammography specifically in those patients with dense breast parenchymal tissue.
Other endpoints of the study are:
- to determine the accuracy of Cyrcadia CBR™, including the positive predictive value, negative predictive value, false negative rate and false positive rate.
- to determine the optimal wear time for the Cyrcadia CBR™.
- to demonstrate substantial equivalent or improved results when applied to Cyrcadia original patient case study with identical advanced neural network analysis computational results.
Study subjects will be followed at 6, 12, 18, and 24 months to update their clinical status.

Experimental: Cyrcadia CBR™ Device
Cyrcadia CBR™ device, including adhesive patches on both breasts connected to a small recorder, is placed on the study subject for 2 to 24 hours. After the test period, the CBR™ will be removed and the data will be downloaded to a central site for analysis.There are no interventions after the CBR™ is removed from the Study Subject

- Predictive Analytic Analysis (PAA) Sensitivity and Specificity [ Time Frame: 7 to 30 days after CBR placement ]The data is analyzed using a predefined set of algorithms, referred to as Predictive Analytic Analysis (PAA) Outcome is measured by: NUMBER OF PATIENTS WHOSE INVESTIGATIVE CBR DEVISE RESULTS MATCH OF THOSE OF THE BIOPSY RESULTS.
