Oncocyte to Present New Data Confirming Association of IO Score with Response to Immunotherapy Treatment for Bladder Cancer at the American Association for Cancer Research Annual Meeting 2022

Poster outlines data showing Oncocyte's DetermaIO™ tool can inform therapeutic decisions and has the potential to improve outcomes for patients with bladder cancer

IRVINE, Calif., March 28, 2022 (GLOBE NEWSWIRE) -- Oncocyte Corporation OCX, a precision diagnostics company with the mission to improve patient outcomes by providing personalized insights that inform critical decisions throughout the patient care journey, today announced that it will present new confirmatory data on DetermaIO™, its 27-gene expression test used to identify responders to immune checkpoint inhibitor (ICI) therapies, at the American Association for Cancer Research (AACR) Annual Meeting 2022, taking place April 8-13, 2022 in New Orleans.

The analysis in the poster builds on previous data, which showed that IO Score correlates with response to Genentech's Tecentriq^® (atezolizumab) ICI therapy for bladder cancer (mUC). The data to be presented at the AACR Annual Meeting 2022 confirm the association of the IO Score with response to ICI treatment in a second, independent, mUC cohort using the same algorithm and threshold previously established and validated in bladder and other tumor types.

Launched for clinical use in Q4 of 2021, DetermaIO has demonstrated the ability to identify responders to ICIs in Lung, TNBC, and Bladder cancers, and across four approved immunotherapies - Keytruda^®, Opdivo^®, Tecentriq^® and Imfinzi^® - suggesting a potential pan-cancer and pan-immunotherapy utility in both primary and metastatic settings. Following are details of the data accepted to the AACR Annual Meeting 2022:

• Title: 1272 / 19 – Confirmatory study of the IO Score, a tumor immune microenvironment (TIME) classifier, demonstrates efficacy in a real-world cohort of metastatic urothelial cancer (mUC) patients treated with immune checkpoint inhibitors (ICIs)
  Session type: PO.CL11.07 – Biomarkers Predictive of Therapeutic Benefit 2
  Authors:  Nielsen, T., et al.
  Date and time: April 11, 2022 | 9:00AM – 12:30PM EST
  

The abstract is currently available online at the AACR Annual Meeting 2022 website. Oncocyte will be distributing a data press release at 9AM EST on Monday, April 11, summarizing poster results and the implications for DetermaIO.

Oncocyte's DetermaIO test is a precision diagnostic designed to determine the likelihood of response to immunotherapy and is the first and only test to measure the entire tumor microenvironment (TME). By evaluating the entire TME, the test can help identify patients primed to respond to immunotherapy and patients who may not respond as well, allowing for physicians and their patients to make informed decisions about their treatment journey.
