CHICAGO–(BUSINESS WIRE)–Tempus AI, Inc. (NASDAQ: TEM), a technology company leading the adoption of AI to advance precision medicine and patient care, today announced a collaboration to develop a companion diagnostic (CDx) test with Verastem Oncology (Nasdaq: VSTM), a biopharmaceutical company committed to advancing new medicines for patients with RAS/MAPK pathway-driven cancers. Tempus completed confirmatory testing in Verastem’s Phase 2 RAMP-201 clinical trial, which evaluated the combination of avutometinib and defactinib to treat recurrent low-grade serous ovarian cancer (LGSOC) and was the basis of the recent U.S. Food and Drug Administration’s (FDA) accelerated approval of the combination in KRAS-mutated recurrent LGSOC.
LGSOC is a rare form of ovarian cancer that disproportionately affects younger women, is highly recurrent and has a poor response rate to chemotherapy. It accounts for approximately 6% to 10% of serous ovarian cancers1. Tempus’ FDA-approved xT CDx assay is being leveraged as an investigational assay in Verastem’s global Phase 3 RAMP-301 clinical trial. The investigational assay prospectively assesses KRAS status in patients with recurrent LGSOC to group patients into KRAS-mutation or KRAS-wild type cohorts for analysis in the primary and secondary endpoints of the study.
“We look forward to continuing to work with Verastem to pursue an unmet need for patients with LGSOC, who, until now, had very few treatment options,” said Mike Yasiejko, Executive Vice President and General Manager, Genomics, at Tempus. “Our xT CDx assay is uniquely positioned to support this work.”
“Collaborating with Tempus to evaluate KRAS mutation status using the xT assay was an important component of the RAMP-201 clinical trial. Continuing our collaboration to fully develop a CDx assay is part of our post-marketing commitment to the FDA for our recent accelerated approval of avutometinib plus defactinib and is a critical step in bringing targeted therapies to patients with recurrent KRAS-mutant LGSOC,” said John Hayslip, MD, Chief Medical Officer of Verastem Oncology.
xT CDx is a qualitative Next Generation Sequencing (NGS)-based in vitro diagnostic device intended for use in the detection of substitutions (single nucleotide variants (SNVs) and multi-nucleotide variants (MNVs)) and insertion and deletion alterations (INDELs) in 648 genes, as well as microsatellite instability (MSI) status, using DNA isolated from Formalin-Fixed Paraffin Embedded (FFPE) tumor tissue specimens, and DNA isolated from matched normal blood or saliva specimens, from previously diagnosed cancer patients with solid malignant neoplasms. The test is intended as a CDx to identify patients who may benefit from treatment with the targeted therapies listed in the Companion Diagnostic Indications table in accordance with the approved therapeutic product labeling. Additionally, xT CDx is intended to provide tumor mutation profiling to be used by qualified health care professionals in accordance with professional guidelines in oncology for patients with previously diagnosed solid malignant neoplasms. Genomic findings other than those listed in the Companion Diagnostic Indications table are not prescriptive or conclusive for labeled use of any specific therapeutic product. xT CDx is a single-site assay performed at Tempus AI, Inc., Chicago, IL.
