DetermaIO(TM) Clinical Test to be used in SWOG Cancer Research Network Biomarker Study for Breast Cancer

2022-10-06 08:00 ET - News Release

IRVINE, Calif., Oct. 06, 2022 (GLOBE NEWSWIRE) -- Oncocyte Corporation (Nasdaq: 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 DetermaIO has been selected by the SWOG Cancer Research Network, an independent global cancer research community that designs and conducts publicly funded clinical trials, to be used in a prospectively designed biomarker study of breast cancer tissues. These tissues were collected during the S1418 Phase III randomized clinical trial of Keytruda(TM) (pembrolizumab) in primary triple negative breast cancer (TNBC).

S1418 is a clinical trial conducted by SWOG and sponsored by the National Cancer Institute. The trial enrolled triple negative breast cancer (TNBC) patients who were treated with standard of care preoperative chemotherapy and still had residual cancer that could be detected after chemotherapy at the time of breast surgery. Patients with cancer that measured >1 cm and/or had positive lymph nodes were randomized for observation or one year of treatment with Keytruda(TM).

"We are excited to partner with Oncocyte to test DetermaIO in the S1418 trial," said Lajos Pusztai, MD, principal investigator. "Identifying specific patient populations who benefit from postoperative pembrolizumab is important because of the autoimmune side effects that these drugs could cause and the substantial costs involved. Targeting therapy to those who need it is the key promise of predictive biomarkers."

DetermaIO was selected by SWOG as part of a grant proposal to the NCI's Biomarker, Imaging, and Quality of Life Studies Funding Program. This was a highly competitive process open to all cancer types and trials supported by the NCI's Cancer Therapy Evaluation Program. To qualify for the biomarker submission, the assay needed to be technically and clinically validated, and therefore ready for clinical use. The submissions were reviewed by an independent scientific review committee of the NCI.

DetermaIO will become a defined secondary endpoint for the ongoing clinical trial. If successful, the study will support the use of DetermaIO to identify patients who received standard pre-operative chemotherapy, that would likely benefit from a year of Keytruda(TM) treatment after surgery.

"Over their 66-year history, SWOG clinical trials have changed the standards of cancer care by providing unbiased, well powered clinical studies to validate prescriptive outcomes that inform patient management guidelines," said Rob Seitz, Head of Immune Oncology at Oncocyte. "To be partnered with SWOG, in a prospectively designed biomarker study in a large, randomized clinical trial, marks a major milestone for DetermaIO."
