Find Biomarkers in More Than 350 Fusion Transcripts

Fusion genes are hybrid genes that form as a result of chromosomal rearrangements or abnormal transcription (Figure 1) and are known to be one of the major drivers behind cancer initiation and progression. Gene fusion can be used in the diagnosis of a variety of cancers. In 2018, the FDA approved the first tumor agnostic treatment for those with TRK fusion based on the clinical benefits observed across numerous tumor types (Figure 2). In some cancer types, fusion genes play particularly important roles, for example, over 10% fusion genes were found in NSCLC and over 15% were found in thyroid cancer^2,3. ACTFusion™ is a targeted, multi-biomarker assay that examines 13 actionable fusion genes and more than 350 known and novel fusion transcripts, which are either included in the NCCNguidelines (e.g. ALK, ROS1, RET, FGFR2/3, NTRK1/2/3, and MET exon 14 skipping)or have been included in global clinical trials (e.g. NRG1).

Precise Identification of Known and Novel Fusion Transcripts to Maximize Treatment

Of the various fusion transcripts in cancers, many targeted drugs have been developed to inhibit specific fusion transcripts in certain cancer types. The tissue-agnostic TRK inhibitor is a newly developed targeted drug that can overcome the complexity in fusion genes, and has already been applied widely across cancer types. Patients diagnosed with different cancer types with various fusion transcripts exhibited a 75% response rate in a clinical trial studying the TRK inhibitor.⁵ Precise identification of fusion transcripts provides solid indications among treatment options to maximize effectiveness.
