Guardant Health

The firm said revenues from its precision oncology business increased 98 percent in Q4, driven by higher testing volume and increased revenue per test.

The index — which outperformed the Dow Jones, the Nasdaq, and the Biotechnology Index this month — gained more than 8 percent.

Data being presented at the upcoming AACR meeting show that Guardant's liquid biopsy test provided more accurate and rapid mutation detection than tissue genotyping.

A busy second day of the JP Morgan conference saw Thermo Fisher's Marc Casper discuss the firm's R&D focus and Exact Sciences' Kevin Conroy discuss plans for Cologuard sales growth.

Plans are in place for a Guardant360-based assay to predict response to AsztraZeneca's Tagrisso and for a blood-based TMB test using the larger GuardantOmni panel.

At the conference, researchers presented data from a number of studies using molecular diagnostic tools to better characterize breast cancer recurrence and treatment outcomes.

At the Business in Personalized Medicine Summit last week, the company also said it has generated promising data from a pilot study for early detection of lung cancer.

Following recent publications and anticipating the readout from its NILE study next year, the company plans to make the case that its liquid biopsy approach performs as well as tissue tests.

The company reported revenues of $21.7 million compared to $11.1 million in the year-ago quarter, overshooting analysts' expectations of $17.5 million.

Guardant's lab will make Guardant360 available to doctors and their patients in the region to help identify patients eligible for molecularly targeted drugs.
