What is it?
Agilent Resolution ctDx FIRST is a laboratory test that detects a specific mutation in the KRAS gene in circulating cell-free DNA. This test helps doctors identify patients with non-small cell lung cancer who may benefit from personalized treatment with KRAZATI (adagrasib). This laboratory test is a companion diagnostic for the treatment with KRAZATI.
How does it work?
A patient’s blood sample is sent to a lab for testing. The cfDNA is separated from the sample and mixed with chemical substances, called reagents, that find and test it for gene changes. A medical professional reviews the results and sends a report to the patient’s doctor. The doctor uses this information to help create a treatment plan for the patient’s non-small cell lung cancer.
When is it used?
Agilent Resolution ctDx FIRST is used to test the blood of patients with non-small cell lung cancer may be eligible for a specific therapy or personalized treatment for their cancer.
However, if the specific mutation in the KRAS gene is not found, then the patient’s eligibility for treatment of non-small cell lung cancer with KRAZATI (adagrasib) should be determined by testing their tumor tissue specimen with an FDA-approved tumor tissue test, unless a tumor biopsy cannot be done.
What will it accomplish?
Test results from the Agilent Resolution ctDx FIRST test are used to help doctors determine if a patient with non-small cell lung cancer may benefit from treatment with KRAZATI (adagrasib).
When should it not be used?
There are no known reasons not to use this test.
