Foundation Medicine Expands Existing Collaboration with Bristol Myers Squibb to Develop a Next-Generation Sequencing Companion Diagnostic to Identify Patients with Homozygous MTAP Deletion
Homozygous deletion is a major cause of MTAP deficiency.1 Copy number calling can have low signal-to-noise ratio, making the alterations challenging to accurately identify. FoundationOne CDx is a tissue-based next-generation sequencing test approved by the FDA to detect copy number loss. Accurate reporting of homozygous deletion can help identify eligible patients for targeted therapies.
“Homozygous MTAP deletion is a critical biomarker, yet one that can be difficult to detect without an assay that unveils blind spots others interpret as noise,” said

About
About FoundationOne®CDx
FoundationOne®CDx is for prescription use only and is an FDA-approved qualitative next-generation sequencing based in vitro diagnostic test for advanced cancer patients with solid tumors. The test analyzes 324 genes as well as genomic signatures including microsatellite instability (MSI) and tumor mutational burden (TMB) and is a companion diagnostic to identify patients who may benefit from treatment with specific therapies in accordance with the approved therapeutic product labeling. Additional genomic findings may be reported and are not prescriptive or conclusive for labeled use of any specific therapeutic product. Use of the test does not guarantee a patient will be matched to a treatment. A negative result does not rule out the presence of an alteration. Some patients may require a biopsy which may pose a risk. For the complete label, including companion diagnostic indications and important risk information, please visit www.F1CDxLabel.com.
