    WHY CHOOSE personalizedx FOR ALK?

    When an oncologist is considering the application of a targeted therapeutic drug for a patient, it’s important to have reliable diagnostic test results. For NSCLC patients for whom the targeted drug XALKORI® may be appropriate, there is an FDA-approved companion diagnostic, commercially known as Vysis ALK (Vysis ALK Break Apart FISH Probe), a FISH-based (fluorescence in situ hybridization) test.

    Vysis ALK has these primary benefits:

    • The test accurately identifies ALK gene rearrangements in NSCLC patients.
    • Early FISH testing at diagnosis can assist physicians in determining appropriate ALK-directed therapy.
    • Vysis ALK is the only FDA-approved ALK companion diagnostic validated in XALKORI® (crizotinib) clinical trials. 

    The National Comprehensive Cancer Network (NCCN GUIDELINES™) recognizes the Vysis ALK Break Apart FISH Probe Kit (Vysis ALK) as a specifically designed method for identifying ALK-rearranged adenocarcinomas.1  Vysis ALK provides reliable information to oncologists that can aid in the appropriate application of ALK-directed therapy.

    Vysis ALK is intended for all NSCLC tissue specimens, including not otherwise specified (NOS) specimens.

    Intended Use

    The Vysis ALK Break Apart FISH Probe Kit is a qualitative test to detect rearrangements involving the ALK gene via fluorescence in situ hybridization (FISH) in formalin-fixed paraffin-embedded (FFPE) non-small cell lung cancer (NSCLC) tissue specimens to aid in identifying those patients eligible for treatment with XALKORI® (crizotinib).
    The test is for prescription use only.

    Limitations of the Procedure

    • Optimal performance of this test requires appropriate specimen handling, preparation, and storage as described in the instructions for use.
    • The Vysis ALK Break Apart FISH Probe Kit has been optimized only for identifying and quantifying rearrangements of the ALK gene from formalin-fixed, paraffin-embedded human NSCLC tissue specimens. The assay should be performed only on 10% neutral buffered formalin FFPE human lung cancer tissue. Other types of specimens or fixatives should not be used.
    • The performance of the Vysis ALK Break Apart FISH Probe Kit was established using the procedures provided in the assay package insert only. Modifications to the procedures may alter the performance of the assay.
    • The clinical interpretation of any test results should be evaluated within the context of the patient’s medical history and other diagnostic laboratory test results.
    • FISH assay results may not be informative if the specimen quality and/or specimen slide preparation is inadequate.
    • Technologists performing the FISH signal enumeration must be capable of visually distinguishing between the orange, green, and yellow signals.
