First companion diagnostic claim for Illumina's TruSight™ Oncology Comprehensive (EU) test enables targeted therapy with Bayer's VITRAKVI® (larotrectinib) for patients with NTRK fusion cancer
SAN DIEGO, May 24, 2022 /PRNewswire/ -- Illumina, Inc. (NASDAQ: ILMN), a global leader in DNA sequencing and array-based technologies, today announced the addition of a companion diagnostic (CDx) indication to its CE-marked in vitro diagnostic TruSight™ Oncology (TSO) Comprehensive (EU) test. This single test kit, recently launched across Europe, assesses multiple tumor genes and biomarkers to reveal the specific molecular profile of a patient's cancer. The CDx pan-cancer indication will allow identification of cancer patients with solid tumors who are positive for neurotrophic tyrosine receptor kinase (NTRK) gene fusions including NTRK1, NTRK2 or NTRK3, and may benefit from targeted therapy with Bayer's VITRAKVI® (larotrectinib), in accordance with the approved therapeutic labeling.
TSO Comprehensive (EU) is a comprehensive genomic profiling (CGP) test which combines less prevalent biomarkers with more prevalent ones in the same test, using a single biopsy specimen. This helps maximize the chances of identifying an actionable alteration so that patients can be treated with a targeted therapy or enrolled into a clinical trial based on their unique tumor genomic profile. The addition of this first CDx claim specific to NTRK gene fusions, a rare but highly actionable biomarker, helps provide patients harboring this genetic alteration with an opportunity to benefit from larotrectinib, a genomically matched treatment.
"This CDx claim, developed in partnership with Bayer, is the first of a series under development, building upon Illumina's broad portfolio of oncology partnerships with industry leaders to advance cancer diagnostics and precision medicine," said Paula Dowdy, Senior Vice President and General Manager of Illumina for Europe, the Middle East, and Africa. "We continue to focus on unlocking the potential of new biomarkers to identify those most likely to benefit from precision medicines so that no patient is left behind—we don't want anyone to miss the opportunity to have their biomarker detected and gain access to a potentially life-saving therapy."
Across most solid cancer tumor types, NTRK gene fusions can have a rare prevalence of 0.1-3% and can be challenging to detect as these genes fuse with many different partners, many of them previously unknown. Most CDx tests are specific to one type of cancer, but the NTRK claim is pan-cancer, enabling TSO Comprehensive (EU) to target multiple solid tumor types and a broad range of known and novel gene fusion partners across all three NTRK genes. This helps maximize the chances of finding actionable information from each patient's biopsy, to inform treatment with larotrectinib.
"Since it launched four years ago, VITRAKVI has demonstrated high response rates and highly durable responses in adults and children with TRK fusion cancer," said Christine Roth, Member of the Executive Committee of Bayer's Pharmaceuticals Division and Head of Bayer's Oncology Strategic Business Unit. "The CE marking of Illumina's TSO Comprehensive (EU) assay inclusive of NTRK gene fusion detection for VITRAKVI is an important advance in enabling precision oncology for patients in Europe. Assays that enable precision oncology through comprehensive genomic testing are crucial for informing optimal treatment plans and help to ensure the best possible outcomes for cancer patients. We look forward to continuing to collaborate with Illumina to ensure that more patients are evaluated comprehensively inclusive of NTRK gene fusions."
The performance of TSO Comprehensive (EU) with NTRK fusions was assessed by analytical and clinical validation studies. Pooled data from three clinical trials, LOXO-TRK-14001 (NCT02122913), NAVIGATE (NCT02576431) and SCOUT (NCT02637687), were used to demonstrate the clinical effectiveness and safety of TSO Comprehensive (EU) in identifying NTRK1, NTRK2 and NTRK3 gene fusion positive patients who may be eligible for treatment with larotrectinib. The primary endpoint was the overall response rate (ORR), measured as the patient presenting either a complete response, a surgical complete response or partial response, to larotrectinib.
"We were delighted to be the clinical study partner for Illumina in this significant achievement of the first CDx claim for the TSO Comprehensive (EU) panel," said Professor Richard Kennedy, Global VP of Biomarker Development & Medical Director, Almac Diagnostic Services. "TSO Comprehensive (EU) represents a powerful and versatile platform with a broad range of cancer-relevant content, and we recognize its value to our biopharma partners, for the development and delivery of companion diagnostics to further precision medicines."
Illumina has a growing pipeline of CDx claims under development through partnerships with pharmaceutical companies, which will be added to TSO Comprehensive (EU) following appropriate regulatory approvals. These CDx claims will help unlock groundbreaking targeted therapies and immunotherapies to make a difference in the lives of cancer patients. As Illumina continues to expand its broad portfolio of oncology partnerships with industry leaders, the company aims to advance cancer diagnostics and precision medicine.
TruSight Oncology Comprehensive is an in vitro diagnostic test that uses targeted next generation sequencing to detect variants in 517 genes using nucleic acids extracted from formalin-fixed, paraffin embedded (FFPE) tumor tissue samples from cancer patients with solid malignant neoplasms using the Illumina® NextSeq™ 550Dx instrument. The test can be used to detect single nucleotide variants, multi-nucleotide variants, insertions, deletions and gene amplifications from DNA, and gene fusions and splice variants from RNA. The test also reports a Tumor Mutational Burden (TMB) score and Microsatellite Instability (MSI) status.
The test is intended as a companion diagnostic to identify cancer patients for treatment with the targeted therapy listed in Table 1, in accordance with the approved therapeutic product labeling. In addition, the test is intended to provide tumor profiling information for use by qualified healthcare professionals in accordance with professional guidelines and is not conclusive or prescriptive for labeled use of any specific therapeutic product.

VITRAKVI™ (larotrectinib), a first-in-class oral TRK inhibitor, was exclusively designed to treat tumors that have an NTRK gene fusion. The compound has demonstrated high response rates and highly durable responses of over four years in adults and children with TRK fusion cancer, including central nervous system (CNS) tumors. To date, it has the largest dataset and longest follow-up data of any TRK inhibitor. The trials are still ongoing, with the latest dataset presented at the European Society for Medical Oncology (ESMO) Congress 2021 and additional updates planned to be presented at upcoming scientific meetings.
Larotrectinib is approved under the brand name Vitrakvi™ in more than 40 countries around the world, including the U.S., countries of the European Union (EU), and most recently in China. Filings in other regions are underway or planned. In the EU, the product is approved for the treatment of adult and pediatric patients with solid tumors that harbor a Neurotrophic Tyrosine Receptor Kinase (NTRK) gene fusion, who have a disease that is locally advanced, metastatic or where surgical resection is likely to result in severe morbidity, and who have no satisfactory treatment options.
