Blood Test for Breast Cancer Associated Auto Antibodies - Improvement of Octava Blood Test

Blood Test for Breast Cancer Associated Auto Antibodies - Improvement of Octava Blood Test

Octava has two versions, each with a different intend of use.

OctavaPink is a qualitative in vitro diagnostic test service, performed by authorized clinical laboratories. The product is used for two following indications:

• Intend of Use #1: OctavaPink is indicated for women above 18 years old, who performed mammography and were determined negative for breast cancer. Being moderately sensitive (>55% sensitivity) the test is able to detect 55% of mammography false negatives. In addition, being highly specific (>95% specificity) it supplies additional evidence for true mammography negative result which will reduce examinees anxiety of being misdiagnosed as a result of high false negative mammography rate (10-30%)
• Intend of Use #2: OctavaPink is indicated for women above 18 years old, who performed biopsy after positive mammography and the biopsy result was negative. Being moderately sensitive (>55% sensitivity) the test is able to detect 55% of biopsy false negatives. In addition being highly specific (>95% specificity) it supplies an additional evidence for true biopsy negative result which reduces examinees anxiety of being misdiagnosed.

OctavBlue is a qualitative in vitro diagnostic test service, performed by EventusDx authorized laboratories. Intend of use of OctavBlue is the following:

• OctavBlue is indicated for women above 18 years old, who performed mammography and received doubtful results. Being highly sensitive (>95% sensitivity) the test can help to reveal 95% of positive cases; and being moderately specific (>55% specificity) - about half of negative cases. The test is not intended to be used as a standalone diagnostic technique but to supply additional information to a physician and help deciding about the further course of diagnosis.

The primary objectives - To improve the specifications of the OctavaPink test and the OctavaBlue test. The current specifications being

1. For the OctavaPink - 95% specificity and 50% sensitivity.
2. For the OctavaBlue - 50% specificity and 95% sensitivity.

The study will be considered as successful in any of the below options -

1. If the new antigens incorporated in the OctavaPink chip will maintain specificity of at least 95% and increase the sensitivity to at least 85%.
2. If the new antigens incorporated in the OctavaBlue chip will maintain sensitivity of at least 95% and increase the specificity to at least 85%.
