London, UK and Phoenix, AZ (May 2, 2022)- AccuStem Sciences, Inc. (OTCQB: ACUT), a clinical stage diagnostics company dedicated to improving outcomes for patients with cancer, announced today that it is taking an extension of time to respond to a formality notice for application 17/907,601 with the US Patent and Trademark Office.

The patent, “Methods And Kits For Determining The Risk Of Breast Cancer Recurrence,” covers a methodology combining the results of the 20-gene StemPrintER test with certain clinical factors to better stratify patients with early stage breast cancer according to their recurrence risk. Studies have shown that StemPrintER is highly prognostic, with “high stemness” patients up to 4 times as likely to experience a distant recurrence as “low stemness” patients. The addition of clinical factors to StemPrintER output appears to improve the strong performance of StemPrintER, especially in relation to identifying a patient’s need for chemotherapy.

“This patent application covers yet another important dimension of the StemPrintER platform and provides additional protection to our proprietary assets,” said Wendy Blosser, Chief Executive Officer of AccuStem. “We believe the addition of clinical factors to StemPrintER will enable physicians to make more effective treatment decisions for their patients from surgery through chemotherapy.”
