- The principle hurdle in developing molecular diagnostics is usually finding the predictive biomarkers out of the 22,000 human genes.Rather than rely on bioinformatics and statistics alone, BIOARRAY uses an innovative approach that finds the best predictive genes by focuses on the genes that are important in the normal, healthy cell organization. The genes that are important to healthy cell organization act like surveillance cameras. We can use our surveillance cameras to provide information as tumor cells progress from organized healthy cells to disorganized cancer cells.By using a discovery approach based on a biological rationale, BIOARRAY test offers several advantages that have scientific and commercial consequences.BIOARRAYâs approach provides more accurate prediction. Moreover, because it is not limited to a particular patient population or chemotherapy, BIOARRAYâs test can predict response in multiple subtypes as well as to multiple chemotherapies. Finally, our approach can support multiple types of diagnostic tests for multiple cancers.

- BIOARRAYâs Response Prediction Test is a personalized diagnostic testthat will accurately predict whether a woman with breast cancer will or will not respond to chemotherapy.The BIOARRAY test is a molecular signature testâbased on a multi-gene signature and proprietary algorithmâthat predicts chemotherapy response.The BIOARRAY test works across multiple breast cancer subtypes, including the aggressive âtriple negativeâ subtype which disproportionately affects younger women and for which there is no tests currently available.BIOARRAYâs test is accurate, quantitative, and cost-effective.By predicting whether a particular woman will response or not respond to chemotherapy treatment, BIOARRAYâs Response Prediction Test will benefit patients and reduce overall treatment costs.
- The BIOARRAY test will build upon already existing infrastructure.A biopsy is currently already done at the time of diagnosis. After diagnosis, but before treatment, a doctor will order the BIOARRAY test be performed. The biopsy will be shipped to BIOARRAYâs laboratory or a lab licensed by BIOARRAY in BIOARRAY supplied packaging. The lab will then extract RNA from the biopsy and conduct a PCR analysis for the relevant biomarkers. Analysis of the expression levels by BIOARRAYâs proprietary algorithm will yield accurate and quantitative information about whether a women will respond to chemotherapy.These results will be transmitted to the patient and her doctor in a secure, confidential, HIPA compliant manner.The test will be paid for through reimbursement by third party payers.

- Specifically, we placed health cells in a 3D culture in a non-organized state. Over a week, the healthy cells will self-organize into a ring, known as an acini or lumen. At this point, the healthy cells stop replicating, have âpolarityâ or spatial awareness , and are structured. BIOARRAY identified the genes that were most important in healthy cells progression from a state of disorganization to a state of organization.Cancer cells are disorganized. Because of mutations they are heterogeneous. They no not stop replicating . They have no polarity or spatial awareness, and they do not organize into a structure. The 22 genes that BIOARRAY identified in studying healthy cells movement from a disorganized state to an organized state are also important in understanding a cancer cellâs reverse pathâfrom healthy organized cells to cancerous disorganized cells.

- Marcia and I, with the Bissell lab, have done a lot of work to study how well the 22 genes determine prognosis in breast cancer. I wonât go into details, except to say that we have looked at three independent datasets that include nearly 700 patients and the signature accurately determined prognosis in each. This work is published in the 3 sources listed here.Determination of prognosis is an aspect of the 22 gene test that we could build in later, but our initial objective is to develop a chemotherapy prediction test.
