AccuStem Sciences, Inc. is a clinical-stage diagnostics company. It is focused on developing and commercializing a suite of genomic tests that support decision-making along the entire continuum of oncology care. It focuses on its proprietary genomic tests, MicroRNA Signature Classifier (MSC) for patients with lung nodules and StemPrintER for patients with early-stage breast cancer. The MSC test, a 24-micro-RNA (miRNA) assay designed to help determine whether lung nodules identified by low-dose computer tomography (LDCT) screening, are benign or malignant. StemPrintER, a 20-gene prognostic assay intended to predict the risk of distant recurrence (DR) in luminal (ER+/HER2-negative) breast cancer patients. The assay is developed to measure the stemness of tumors, or how much a tumor behaves like stem cells, which could indicate how likely a cancer is to recur or be resistant to standard treatments, ultimately impacting how patients are managed by their multidisciplinary care team.
