Los Angeles, October 2, 2023 — The U.S. Food and Drug Administration (FDA) has granted approval for EntroGen’s CRCdx® RAS Mutation Detection Kit as a companion diagnostic for Vectibix® (panitumumab), a targeted therapy used in the treatment of colorectal cancer. This landmark premarket approval (PMA) marks a significant advancement in precision medicine for colorectal cancer patients in that CRCdx® is the first approved real-time PCR-based test in the U.S. that fully meets the biomarker identification requirement for Vectibix®.

The CRCdx® RAS Mutation Detection Kit is a cutting-edge molecular diagnostic tool designed to accurately detect KRAS and NRAS exon 2, 3, and 4 mutations in colorectal cancer patients.  The kit’s high sensitivity and specificity enable clinicians to quickly and easily identify patients most likely to benefit from Vectibix® therapy and avoid unnecessary side effects and costs from treatment.

“We expect CRCdx® to improve access to RAS testing at small and mid-size laboratories by simplifying the testing procedure while improving the turnaround time and lowering the diagnostic costs,” said Matthew Minkovsky, CEO of EntroGen. ”CRCdx® is available immediately,” he added.

About CRCdx® RAS Mutation Detection Kit:

The CRCdx® RAS Mutation Detection Kit is a qualitative real-time PCR in vitro diagnostic test intended for the detection of 35 variants of KRAS and NRAS exon 2, 3, 4 somatic mutations in genomic DNA extracted from formalin-fixed, paraffin-embedded (FFPE) colorectal cancer (CRC) tissue samples. The test is intended as a companion diagnostic (CDx) to aid in the identification of colorectal cancer (CRC) patients who may benefit from treatment with Vectibix (panitumumab) based on a ‘no mutation detected’ test result in accordance with the approved therapeutic product labeling.
