Guardant Health Expands Use of Guardant Reveal™ Liquid Biopsy Test for Residual Disease Detection and Recurrence Monitoring to Include Early-Stage Breast and Lung Cancers

Rhea-AI Summary

Guardant Health Inc. (Nasdaq: GH) has expanded the availability of its innovative blood test, Guardant Reveal™, which detects minimal residual disease in colorectal, breast, and lung cancers without the need for a tissue biopsy. This test enables early identification of patients at higher risk for recurrence post-surgery, promising improved management of early-stage cancer. The Guardant Reveal test can be initiated three weeks post-surgery and outperforms traditional monitoring tools in predicting disease recurrence.

Positive

• Guardant Reveal test now available for breast and lung cancers, broadening its market reach.
• First blood-only test for minimal residual disease detection, reducing the need for invasive procedures.
• Improves early-stage cancer management and identifies patients who may benefit from additional therapy.

Negative

• None.

Only blood test that detects minimal residual disease in patients with solid tumors without need for tissue biopsy now available for three cancers impacting 6 million people in US annually¹

PALO ALTO, Calif.--(BUSINESS WIRE)-- Guardant Health Inc. (Nasdaq: GH), a leading precision oncology company, announced today that Guardant Reveal™, the only tissue-free test for the detection of residual and recurrent disease for colorectal cancer (CRC), is now available for patients with breast and lung cancers.

The Guardant Reveal blood test improves the management of early-stage cancer patients by detecting circulating tumor DNA (ctDNA) in blood after surgery—without the need for a tissue biopsy—to identify patients with minimal residual disease (MRD) who have a higher risk for recurrence and may benefit from additional therapy. The test has also been shown to predict disease recurrence more effectively than current standard-of-care tools, like carcinoembryonic antigen (CEA) tests, which are limited in their ability to identify patients at high risk for recurrence.²

“We are very pleased to be able to make the Guardant Reveal test available to patients with breast and lung cancer, where obtaining a tissue biopsy can be a challenge,” said Helmy Eltoukhy, Guardant Health co-CEO. “With a simple blood draw, this test allows oncologists to confidently assess risk for their breast and lung cancer patients so they can quickly identify those patients who may benefit from therapy after surgery, as well as detect cancer recurrence earlier.”

The Guardant Reveal test may be initiated as soon as three weeks after surgery. For more information, visit guardantreveal.com.

About Guardant Reveal

Guardant Reveal is the first blood-only test that detects residual and recurrent disease in patients with Stage II and III CRC, breast or lung cancer without the need for a tissue biopsy. Combining genomic and epigenomic signals, the test detects ctDNA in blood after surgery to identify patients with residual disease who may benefit most from adjuvant therapy, and to monitor for recurrence of disease in previously diagnosed patients.
