Another snippet from the original RNS:-
"It is recognised that breast cancer can be highly heterogeneous and that HER2 status can change over time. In addition, results from a recent high impact study have revealed that patients categorised with HER2-low breast cancer (and defined as immunohistochemistry (IHC) score 1+ and 2+ and HER2-negative by FISH), can in fact, benefit from new HER2 targeted antibody-drug conjugates, where typical HER2 targeted drugs have previously been reserved for HER2-positive (HER2 IHC 3+ and/or HER2 FISH positive) breast cancer patients. This new understanding is driving the adoption of HER2-low targeted drugs such as ENHERTU(R) marketed by Daiichi-Sankyo and *****AstraZeneca*****.
This changing market dynamic has provided ANGLE and BioView with a major commercial opportunity to develop a quantitative CTC-based HER2 assay, to assess HER2 protein expression and/or gene amplification levels by analysing fluorescence intensities. This would be the only product-based solution on the market for this purpose ****leveraging both companies' previous FDA product clearances*****. Unlike current standard of care tests developed for use on FFPE tissue, a CTC HER2 assay could be used for longitudinal monitoring of HER2 status throughout disease progression, thereby ensuring the patient is targeted for the most appropriate treatment at every stage.
