Event Summary

Roche announced the European Union In Vitro Diagnostic Regulation (IVDR) approval of several label expansions for its VENTANA MMR RxDx Panel. This immunohistochemistry (IHC) companion diagnostic test identifies cancer patients' mismatch repair (MMR) status, which is crucial for determining eligibility for certain precision oncology therapies. The expanded label now includes five cancer types and six indications, making the panel available in IVDR-regulated countries. This development is significant for patients with various cancers, including metastatic colorectal cancer, advanced or recurrent endometrial carcinoma, and gastric, small intestine, or biliary cancer, as it standardizes testing and expands access to therapies like Pembrolizumab from Merck & Co., Durvalumab and Olaparib from AstraZeneca, and Dostarlimab from GSK plc.
