A Prospective Observational Study to Examine, in Routine Clinical Practice in the US, Practice Patterns and Impact on Clinical Decision Making Associated With the FoundationOne™ Next Generation Sequencing (NGS) Test

Molecular testing of tumors, using techniques such as next-generation sequencing (NGS), facilitates an individualized approach to cancer treatment by sub-classifying diseases on an individual basis. Physicians can utilize an in depth understanding of disease at a molecular level to optimize therapy by selecting the most appropriate drugs and therapeutic targets. Genomic profiling has identified multiple genomic aberrations that are predictive markers for treatment response with targeted therapeutics.

FoundationOne™ is a commercially available molecular diagnostics test, for all solid tumor types, that analyzes routine clinical specimens for somatic alterations in relevant cancer-related genes. This validated in vitro diagnostic test, is performed in a single Clinical Laboratory Improvement Amendments (CLIA) certified and College of American Pathologists (CAP) approved laboratory at Foundation Medicine, Inc. It provides individualized, potentially actionable information regarding a patient's molecular cancer subtype that can be used by physicians to tailor treatment options.

With the recent commercial availability of the FoundationOne™ test, knowledge gaps exist regarding practice patterns associated with the use of this test in routine clinical practice and the impact of this test on clinical decision making. There is limited information regarding physician and patient characteristics that determine which patients receive the test, rationale for patient selection, and how physicians interpret and use the test results. Findings from this study will help to optimize patient selection and maximize the clinical impact of the test in terms of guiding therapy.
