Company developments and clinical data

Natera also reported progress on its clinical and product fronts. The company published two peer-reviewed studies that evaluated its Signatera circulating tumor DNA (ctDNA) assay in patients with anal squamous cell carcinoma and those with locally advanced rectal cancer. According to the studies, patients who tested negative for Signatera at baseline or who cleared ctDNA during treatment experienced 100% one-year overall survival and 100% one-year progression-free survival.

In addition to the Signatera results, Natera launched a new whole genome sequencing test called Zenith genomics, developed in collaboration with MyOme. The test uses long-read sequencing technology to detect rare genetic conditions and complex genomic features, and Natera is presenting data on the test at a major genetics meeting.


Analyst activity

On the analyst front, Morgan Stanley adjusted its price target for Natera to $250 from $265 while maintaining an Overweight rating, citing updates to its financial models. Canaccord Genuity reiterated a Buy rating, pointing to fourth-quarter results that outperformed the company’s preannouncements.
