Oncocyte to Present DetermaIO™ Test Data at the 2020 Society for Immunotherapy of Cancer (SITC) Conference

Data show DetermaIO™ may help to select effective therapeutic options for immune checkpoint inhibitor (ICI) resistant patients with non-small cell lung cancer (NSCLC) and triple-negative breast cancer (TNBC)


IRVINE, Calif., Nov. 09, 2020 (GLOBE NEWSWIRE) -- Oncocyte Corporation (NYSE American: OCX), a molecular diagnostics company with a mission to provide actionable answers at critical decision points across the cancer care continuum, today announced plans to present data at the Society for Immunotherapy of Cancer (SITC) 2020 Virtual Conference on its test, DetermaIO™. These data indicate that DetermaIO can identify viable treatment pathways for many cancer patients who are resistant to immune checkpoint inhibitors (ICIs).

In the United States alone, it is estimated that up to 750,000 patients annually may be eligible to be treated with ICIs. Yet data indicates that only 12-40 percent of patients who receive ICI therapy respond favorably. That results in the significant need for a test like DetermaIO to predict whether patients are likely to respond to ICI therapy. In fact, likelihood of response is the principal clinical question driving the emerging $3B+ U.S. ICI therapy selection testing market. DetermaIO measures the tumor immune microenvironment to identify which patients are likely to respond to ICI therapy and which patients are likely to be resistant. To treat resistant patients, biopharmaceutical companies are developing next generation therapeutics that modulate the immune response in novel ways. The data being presented at SITC show that Oncocyte’s DetermaIO test may help biopharmaceutical companies identify patients in their clinical trials who may be more likely to respond to ICI therapy as they develop the emerging class of second-generation targeted and immune therapies.

Data to be presented at the SITC conference will show that DetermaIO may be able to identify subtypes of patients with a higher likelihood of responding to specific classes of therapeutics. That data will explore pathway analysis of DetermaIO in TNBC patients and NSCLC mouse models for immune targeted agents showing that DetermaIO may be able to identify subtypes of patients who are more likely to respond to specific classes of targeted therapeutics. DetermaIO is currently available for research use to support pharmaceutical trials of these second-generation drugs that are often developed in combination with ICI immunotherapies.

“These results have encouraged us to develop DetermaIO as a potential biomarker for therapeutics designed to overcome resistance to checkpoint inhibitors or to be used in combination with immunotherapies,” said Doug Ross, M.D., Ph.D., Chief Medical Officer of Oncocyte. “We have previously shown data supporting the ability of DetermaIO to improve prediction of response to ICIs, and we are encouraged that these new data suggest that DetermaIO may also be useful in targeting alternative treatment options for ICI resistant patients.”

About Oncocyte Corporation
Oncocyte is a molecular diagnostics company whose mission is to provide actionable answers at critical decision points across the cancer care continuum. The Company’s proprietary tests and pharmaceutical company services aim to save lives and improve outcomes by accelerating and optimizing the diagnosis and treatment of cancer. The Company’s tests and services present multiple opportunities to advance cancer care while driving the growth of its revenue across four growth engines. Oncocyte recently launched DetermaRx™, a treatment stratification test that enables the identification of early-stage lung cancer patients at high risk for recurrence post-resection, allowing them to be treated when their cancer may be more responsive to adjuvant chemotherapy. Oncocyte also has launched, as a Research Use tool for Biopharma clinical trials, DetermaIO™, a gene expression test that identifies patients more likely to respond to checkpoint inhibitor immunotherapies. The Company’s pharmaceutical company services help pharmaceutical companies to develop new cancer treatments, many of which may be linked to Oncocyte’s diagnostic tests. The final growth engine is the recently licensed CNI test for blood based therapy monitoring in patients receiving immune therapy, which the company plans to launch as a Research Use tool for Biopharma clinical trials in 2021.
