Clinical validation study supporting the use of BREVAGenplus® in breast cancer risk assessment

 

Melbourne, Australia, 17 December 2014:  Molecular diagnostics company Genetic Technologies Limited (ASX: GTG; NASDAQ: GENE, “Company”) announces that findings from a new research study show that adding a panel of 77 single-nucleotide polymorphisms (“SNPs”) improves the predictive accuracy of four commonly used breast cancer risk assessment models. This same panel of 77 SNPs is used in the Company’s recently released BREVAGenplus®, an easy-to-use predictive risk test for sporadic, or non-hereditary, breast cancer. Results were presented at the 2014 San Antonio Breast Cancer Symposium, on December 13, 2014.

 

The study, entitled “Value of Adding Single-Nucleotide Polymorphism Panel Markers to Phenotypic Algorithms of Breast Cancer Risk,” was conducted under the supervision of Prof. John L. Hopper and first authored by Dr. Gillian S. Dite from the Centre for Molecular Epidemiology at the University of Melbourne. The study investigated the impact of adding the same 77 SNP panel used in BREVAGenplus® to the following breast cancer prediction models: BOADICEA and BRCAPRO, both of which are based on pedigree data for breast and ovarian cancer; BCRAT (Gail score), which is based on established risk factors for breast cancer and family history as represented by the number of first-degree relatives with breast cancer; and IBIS, which combines information on both familial and personal risk factors for breast cancer.

 

Results show that adding a SNP risk score to these four breast cancer prediction models can improve risk estimates obtained by these models. Because these models place different weighting on different risk components, this new study also shows that combining the 77 SNP score with the most patient-appropriate breast cancer risk-assessment model can improve a clinician’s ability to identify high-risk women in different patient populations.
  
The researchers studied a population-based sample of 750 cases and 405 controls from the Australian Breast Cancer Family Registry and utilized the same methodology as a previous study of seven SNPs conducted by the same researchers.(1) This new Australian study builds on previous observations that including information on multiple SNPs can improve the discriminatory accuracy of BCRAT risk assessment model (Mealiffe et al), as well as extending that observation to more recently identified SNPs associated with breast cancer. This study is expected to be published in a peer-reviewed scientific journal in early 2015.

 

Commenting on the findings, Genetic Technologies’ Chief Executive Officer Ms Alison Mew said “We are very pleased to see these clinical validation results which demonstrate that incorporating genetic information derived from the SNP panel utilized in BREVAGenplus®, improves the discriminatory accuracy of these four breast cancer risk tools, including BCRAT, which is the model on which BREVAGenplus® is based.”

 

BREVAGenplus is an improved version of the Company’s first generation breast cancer risk prediction test, BREVAGenTM. BREVAGenplus uses the original seven BREVAGen SNPs, plus a further 70 SNPs that, with an expanded SNP panel, reclassifies patients’ risk of developing breast cancer with an ~20% improvement in predictive accuracy, over the first generation test. Importantly, the value of using SNPs as genetic markers for risk is receiving increasing attention in the medical literature.

Furthermore, clinical studies have been conducted to demonstrate the applicability of BREVAGenplus to the African American and Hispanic populations. Publication of this data is expected in first quarter of 2015, removing a significant barrier to test acceptance in the US market.

 

BREVAGenplus was launched in October 2014, to coincide with Breast Cancer Awareness Month, and has effectively been a re-launch of the product, accompanied by a strategic change in product placement to target large breast and imaging centres as part of a long-term growth plan. Discussions are well-progressed with a number of such centres, with the “on-boarding” process expected to be complete early in 2015.
