OBD EpiSwitch® CiRT well received at ASCO 2022
Oxford BioDynamics' simple blood test that predicts patient's response to Immune Checkpoint Inhibitors well received at ASCO 2022
· Immune Checkpoint Inhibitor (ICI) therapies are ineffective in up to 70% of patients receiving them, resulting in a critical need for early determination of patient response.
· EpiSwitch® CiRT is a first-of-its-kind precision medicine test that predicts a patient's likely response to ICI therapies. Accurate prediction of response is expected to save healthcare systems significant amounts due to the high cost of ICIs and subsequent adverse responses.
· The test has shown high sensitivity (93%), specificity (82%) and accuracy (85%) across 15 cancer indications where ICI treatments are available and has seen encouraging uptake by early adopters in the US since launch.
· OBD presented additional data on EpiSwitch CiRT at ASCO 2022 and met numerous practicing clinicians, pharma development teams, hospital systems and healthcare investors interested in the test.
· This simple blood test is now available to millions of cancer patients via their clinicians across the US at the website: myCiRT.com .
Oxford, UK - 14 June 2022 - Oxford BioDynamics Plc (AIM: OBD, the Company), a biotechnology company developing precision medicine tests for immune health based on the EpiSwitch® 3D genomics platform, presented additional data at ASCO 2022 on its flagship CiRT clinical assay to predict patient response to ICI therapies, which was well received.
The EpiSwitch® Checkpoint inhibitor Response Test (CiRT) is a simple blood test available to US-based clinicians, enabling them to advise the millions of cancer patients facing the complex choice between powerful immunotherapy treatments, which might have low response rates and immune-related adverse events, and alternative treatment options.
Launched in February 2022 as a Laboratory Developed Test (LDT), EpiSwitch CiRT is available for immediate clinical utilization in the US via the website: myCiRT.com.
Interest in CiRT at ASCO was significant; OBD representatives held positive meetings with 11 pharma teams, two major US hospital networks , National Cancer Institute-designated comprehensive cancer centers, as well as with clinicians and healthcare investors.
"ASCO was a brilliant opportunity to get the attention of oncologists and the oncology community from around the world," said Dr Jon Burrows, OBD's Chief Executive Officer. "As a small British biotech building our commercial profile, we were overwhelmed by the interest in the Company and EpiSwitch CiRT. We had significantly more meetings than anticipated with practicing oncologists, pharma clinical development teams, hospital administrators and healthcare investors, who welcomed information on the potential use and utility of CiRT. It is highly encouraging that we continue to receive enquiries post-ASCO."
ICIs have been approved as first-line (1L) or second-line (2L) of treatment for 15 different cancer indications. They show remarkable efficacy in treating cancer, and oncologists have actively adopted the use of these therapies. Across the approved indications, approximately 40% of all patients are eligible for ICI therapy [1], and within the class of ICIs, anti-PD-1/PDL-1 antibodies have become some of the most widely prescribed and tested anticancer therapies [2].
Despite their potential efficacy, it has been estimated that ICIs are ineffective for up to 70% of patients treated, and these ineffective therapies in the US alone could add over 42% to annual spend. Currently, there are no predictive tools that accurately report the expected efficacy in individual patients.
This results in substantial unnecessary costs in both time and money to healthcare systems - a situation which is exacerbated by the high prices of ICIs, e.g. Keytruda costs approximately $190,000 in the US. It is estimated that annual savings to the US healthcare system through the personalised administration of ICIs following accurate prognosis could amount to as much as $10B+.
OBD's EpiSwitch CiRT blood test has demonstrated best-in-class performance in the prediction of cancer patient response to ICIs, including anti-PD L1 and anti-PD 1, with high sensitivity (93%), specificity (82%), and accuracy (85%) across several ICIs from multiple pharmaceutical companies, in all 15 key oncological indications.
Dr Steve Mamus, a recognized oncologist serving as Medical Director of Oncology / Hematology and founder of the Cancer Center of Sarasota (FL, USA), commented "EpiSwitch CiRT has demonstrated that it can stratify patients in either a high or low response likelihood category with high accuracy. This promises to add real value - both supporting our decision on whether ICI therapy is appropriate for a patient and giving us a rational approach to stop and/or restart therapy at the right time. We need tools such as EpiSwitch CiRT to provide evidence on whether persevering after an irAE (adverse events related to toxicities) is the right call for an individual patient."
