NeoGenomics and German Breast Group Announce New Data Demonstrating Clinical Potential of the RaDaR MRD Assay in HR+/HER2- Breast Cancer
FT. MYERS, FL / ACCESSWIRE / June 5, 2023 / NeoGenomics, Inc. (NASDAQ:NEO), a leading provider of oncology testing and global contract research services, today announced new data in support of its RaDaR® assay for the detection of molecular residual disease (MRD) and recurrence in patients with high-risk hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer.
Data from a retrospective analysis of the Phase 3 PENELOPE-B study was presented in part at the 2023 ASCO® Annual Meeting on Friday, June 2nd in Chicago, IL.
In collaboration with the trial sponsor, German Breast Group (GBG), the study used NeoGenomics' RaDaR personalized MRD assay to assess the potential of circulating tumor DNA (ctDNA) analysis to predict future clinical relapse of patients enrolled in the PENELOPE-B trial.
"We are delighted that the development of liquid biopsies for the early detection of circulating tumor DNA is moving forward. There is an unmet need for early response evaluation in plenty of clinical situations, and these results support the potential benefits of the clinical utility of individualized assays, such as the RaDaR assay." said Professor Sibylle Loibl, MD, Chief Executive Officer of German Breast Group. "Prognostic and predictive implications of circulating tumor DNA assays still need to be validated on a broader basis. Nevertheless, we are confident that prospective investigations on ctDNA will lead to their clinical application and ultimately improve patient outcomes."
Patients in the trial had already completed neoadjuvant therapy and surgery, with or without radiation. The RaDaR assay analyzed ctDNA in blood samples from 78 patients collected at three points: prior to initiation of standard of care endocrine therapy with either palbociclib or placebo, during therapy, and at the end of treatment. ctDNA positivity was compared to patient outcomes.
Nine percent of the patients had ctDNA detected at baseline (prior to the start of endocrine plus palbociclib or placebo). Of patients undetected at baseline, 4% had ctDNA detected in later samples and of patients detected at baseline, 29% became undetected in later samples, indicating that ctDNA positive patients may benefit from palbociclib. Detection of ctDNA following neoadjuvant chemotherapy, and surgery, is associated with a very high risk of early relapse suggesting clinical imaging and experimental therapy may be warranted for these patients.
The data highlight the potential of the RaDaR assay to provide an early predictor of efficacy of adjuvant endocrine therapy and assess on treatment dynamics, and demonstrates that highly sensitive tumor-informed ctDNA assays can be used successfully after diagnosis and treatment of the original tumor to risk stratify patients.
The RaDaR assay is a personalized, tumor-informed, highly sensitive technology that tracks a set of up to 48 tumor-specific variants in cell-free DNA (cfDNA) within a cancer patient's blood plasma. Built on the proven InVision® platform, the personalized RaDaR assay has been designed to detect minimal residual disease (MRD) and recurrence following curative intent or definitive treatment, and early signs of relapse, and has been validated for clinical use in breast, colorectal, head and neck, as well as lung cancers. MRD is the trace amounts of circulating tumor DNA (ctDNA) that remain after surgery or other cancer treatment.
The RaDaR workflow leverages proprietary algorithms to both create personalized RaDaR panels for each patient and analyze results of a RaDaR test, all culminating in an exceptionally sensitive test with one of the industry's leading limit of detections (LODs) down to 0.001%.
The RaDaR assay is a laboratory developed test (LDT) which has been granted Breakthrough Device Designation by the US FDA for use in the detection of MRD in early-stage cancer patients and has received the CE mark for the detection of MRD and recurrence. RaDaR is also available for pharmaceutical companies, biotechnology companies and commercial entities in early through late-stage cancer development programs across a range of cancer types.
