*Federal Register* notice: FDA is making available a final guidance entitled “Oncology Drug Products Used with Certain In Vitro Diagnostic Tests: Pilot Program.” The document discusses the agency’s intention to pilot a new approach to provide greater transparency on performance characteristics that certain tests for oncology biomarkers should meet. Under this transparency, FDA seeks to support better and more consistent performance of certain laboratory-developed tests used to identify patients for treatment with certain oncology drug products, resulting in better drug selection and improved care for patients with cancer.
