KOL Call Recording - Novel Biomarkers in Identifying Appropriate Responders to Immune Checkpoint Inhibitors

Hosted by Oncocyte (Nasdaq: OCX)

The event will feature a presentation by Key Opinion Leaders (KOLs) David Gandara, MD (UC Davis Comprehensive Cancer Center) and Mamta Parikh, MD, MS (UC Davis Comprehensive Cancer Center), who will present an overview of the use and limitations of currently clinically available biomarkers, such as PD-L1 and tumor mutational burden (TMB), in identifying responders to immunotherapies, specifically immune checkpoint inhibitors (ICI) that are FDA-approved for a broad range of solid tumors.

New data will also be discussed, presented for the first time during an oral symposium at the 2021 American Association for Cancer Research (AACR) Annual Meeting, showing that DetermaIO™, a 27-gene test that assesses the tumor microenvironment to identify immunotherapy responders, has strong performance in identifying responders to atezolizumab in bladder cancer, as measured by overall survival rates in DetermaIO-positive patients who received ICI. This adds to previously presented data in non-small cell lung cancer and triple-negative breast cancer that demonstrates incremental utility beyond PD-L1 and TMB in identifying responders to all currently approved ICIs. 

Evidence now presented for three different cancers suggests a potential pan-cancer application for the test. 

Drs. Parikh and Gandara will be available to answer questions following the formal presentations.

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, through its proprietary tests and pharmaceutical services business, aims to help 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 also driving revenue growth for the Company. Oncocyte launched DetermaRx™, a test that identifies early-stage lung cancer patients who are at high risk for cancer recurrence post-resection and predicts benefit from adjuvant chemotherapy. Oncocyte has also launched DetermaIO™, a gene expression test that assesses the tumor microenvironment to predict response to immunotherapies, as a research use only tool for pharmaceutical and academic clinical trials. To complement DetermaIO™, the Company anticipates launching DetermaTx™, a test to assess mutational status of a tumor to help identify the appropriate targeted therapy, in the second half of 2021. The Company previously announced its planned acquisition of Chronix Biomedical Inc. and its TheraSure™ CNI Monitor test, and also plans to continue with the development of DetermaMx™ as the Company seeks to expand into the blood-based monitoring market. Oncocyte’s pharmaceutical services provide pharmaceutical companies who are developing new cancer treatments a full suite of molecular testing services to support the drug development process.

These statements include those pertaining to the data presented at the 2021 American Association for Cancer Research (AACR) Annual Meeting, the potential use of DetermaIO across multiple tumor types, and other statements about the future expectations, beliefs, goals, plans, or prospects expressed by management. Forward-looking statements involve risks and uncertainties, including, without limitation, the potential impact of COVID-19 on our or any distributor’s financial and operational results, risks inherent in the development and/or commercialization of potential diagnostic tests or products, uncertainty in the results of clinical trials or regulatory approvals, the capacity of our third-party supplied blood sample analytic system to provide consistent and precise analytic results on a commercial scale, potential interruptions to our or any distributor’s supply chain, the need and ability to obtain future capital, maintenance of intellectual property rights in all applicable jurisdictions, and the need to obtain third party reimbursement for patients’ use of any diagnostic tests we commercialize in applicable jurisdictions, and risks inherent in strategic transactions such as failure to realize anticipated benefits, legal, regulatory or political changes in the applicable jurisdictions, accounting and quality controls, greater than estimated allocations of resources to develop and commercialize technologies, or failure to maintain any laboratory accreditation or certification. Actual results may differ materially from the results anticipated in these forward-looking statements and accordingly such statements should be evaluated together with the many uncertainties that affect the business of Oncocyte, particularly those mentioned in the “Risk Factors” and other cautionary statements found in Oncocyte’s Securities and Exchange Commission filings, which are available from the SEC’s website.
