FDA OKs Companion Diagnostic for Endometrial Cancer Therapy
FDA has approved Promega’s OncoMate MSI Dx Analysis System as a companion diagnostic for identifying patients with microsatellite stable endometrial carcinoma who may benefit from treatment with Merck’s Keytruda (pembrolizumab) in combination with Eisai’s Lenvima (lenvatinib). The polymerase chain reaction-based assay is designed to determine microsatellite instability (MSI) status in tumor tissue, helping oncologists tailor immunotherapy treatment strategies for advanced endometrial cancer patients, according to Promega. Assessing MSI status, a biomarker linked to tumor mutation rates and response to immunotherapy, can help guide treatment selection and predict response to checkpoint inhibitors such as Keytruda, it adds.
