FDA Approves Illumina Cancer Test

The FDA has given its approval to Illumina's TruSight Oncology (TSO) Comprehensive test, marking it as the first distributable comprehensive genomic profiling in vitro diagnostic (IVD) kit in the United States. This test is designed to analyze over 500 genes, helping to identify actionable biomarkers in solid tumors, which can significantly aid in making targeted therapy decisions.

The initial approval of the TSO Comprehensive test includes two companion diagnostic (CDx) indications. These indications are for identifying patients with specific gene fusions who could benefit from treatments such as Bayer's Vitrakvi (larotrectinib) or Eli Lilly's Retevmo (selpercatinib). The test provides a broad molecular profiling tool for cancer patients, making it particularly useful for those with neurotrophic tyrosine receptor kinase (NTRK) gene fusions or rearranged during transfection (RET) fusion-positive non-small cell lung cancer (NSCLC).

One of the significant advantages of the TSO Comprehensive test is its ability to detect a wide array of gene fusions, including novel ones. This capability could enhance the identification of patients who might benefit from specific therapies, thereby improving the precision of oncology treatments. The test is designed to improve access to precision oncology, meaning that the results could potentially influence treatment options and determine eligibility for clinical trials.

The TSO Comprehensive test is anticipated to start shipping later this year. In addition to its release, it is noteworthy that Medicare will cover the test for solid tumor indications with CDx claims. This coverage is expected to facilitate wider access to this advanced genomic profiling tool, benefiting a larger number of cancer patients.

Illumina is also actively working on expanding the CDx claims for the TSO Comprehensive test through partnerships with other pharmaceutical companies. This strategic effort aims to broaden the test's applicability and enhance its utility in the field of precision medicine. By collaborating with different pharma companies, Illumina seeks to integrate the TSO Comprehensive test more deeply into various therapeutic contexts, thereby maximizing its impact on cancer treatment.

In summary, Illumina’s FDA-approved TSO Comprehensive test represents a significant advancement in the field of precision oncology. With its ability to analyze over 500 genes and identify actionable biomarkers, it holds promise for improving targeted therapy decisions. Its initial approval for specific gene fusions linked to treatments like Vitrakvi and Retevmo highlights its potential for enhancing patient outcomes. The upcoming shipping of the test and its Medicare coverage further underscore its anticipated contribution to cancer care.
