Information for Clinicians
InVisionFirst®-Lung is a clinical diagnostic laboratory-developed test (LDT) validated for the accurate identification of genomic alterations in 37 genes that helps support the prognosis and therapeutic decisions in patients diagnosed with advanced non-small cell lung cancer (NSCLC).
Using a proprietary enhanced tagged-amplicon Next Generation Sequencing (eTAm-Seq™) technology, this test can detect single nucleotide variants (SNVs), small insertions and deletions (InDels), copy number (CNVs), and structural variants (SV) such as fusions from plasma cell free DNA (cfDNA) with a detection range as low as 0.1% variant allele fraction with a mean read depth of 70,000.
InVisionFirst®– Lung at a glance
Run on two 10 mL blood collection tubes
37 gene panel including NSCLC markers
Turnaround time 7 calendar days from blood draw
Results accessible through secure online portal
Indications for Use / Medicare Coverage1
- When results for EGFR SNVs and InDels; rearrangements in ALK, NTRK1, RET and ROS1; and SNVs for BRAF are not available
- When tissue-based comprehensive genomic profile (CGP) is infeasible (i.e., quantity not sufficient or tissue-based CGP or invasive biopsy is medically contraindicated).
For patients progressing on or after chemotherapy or immunotherapy who have not been tested for EGFR SNVs and indels; rearrangements in ALK, NTRK1, RET and ROS1; and SNVs for BRAFs, and for whom tissue- based CGP is infeasible;
- For patients progressing on EGFR tyrosine kinase inhibitors (TKIs).
* If no genetic alteration is detected by InVisionFirst®-Lung or if circulating tumor DNA (ctDNA) is insufficient/not detected, tissue-based genotyping should be considered. Note: The InVisionFirst®-Lung Assay is not intended for profiling for germline (i.e. inheritable) mutation testing or for therapeutic monitoring.
