Natera’s ctDNA test outperforms standard markers in testicular cancer

AUSTIN - Natera, Inc. (NASDAQ:NTRA), a $22.4 billion market cap diagnostics company with impressive 44% year-over-year revenue growth, announced findings from the largest-ever study of circulating tumor DNA (ctDNA) in testicular cancer patients, showing its Signatera test significantly outperformed standard tumor markers in predicting patient outcomes. According to InvestingPro data, the company maintains a strong gross profit margin of 63%, reflecting its operational efficiency in the diagnostic testing market.

The multi-institutional study, published in the Journal of Clinical Oncology - Precision Oncology, analyzed 324 plasma samples from 74 testicular cancer patients across stages I-III. Researchers used Signatera to assess ctDNA levels before, during, and after treatment. InvestingPro analysis shows the company maintains a healthy financial position with a current ratio of 3.72, indicating strong ability to fund ongoing research and development.

Results demonstrated that patients who tested positive with Signatera had significantly shorter event-free survival compared to those who tested negative. The study found a ctDNA-positivity rate of 91.6% for stage I patients before surgery, and 100% for both stage II and III patients.

In post-surgical settings, Signatera-positive patients showed significantly shorter event-free survival compared to Signatera-negative patients, with a hazard ratio of 5.11. By contrast, standard serum tumor markers failed to show significant predictive value.

During surveillance, the difference was even more pronounced, with Signatera-positive patients experiencing significantly shorter event-free survival (hazard ratio:12.45) compared to Signatera-negative patients. Standard markers again showed no significant predictive value.

Testicular cancer is the most common malignancy in men aged 15-35. While early stages can often be cured with surgery alone, determining which patients need additional treatments has remained challenging.

"These findings demonstrate that ctDNA can identify which patients with testicular cancer are at high risk of recurrence or progression," said Dr. Nabil Adra, associate professor of medicine at Indiana University and principal investigator of the study, according to the press release.

The study suggests Signatera could potentially help clinicians make more informed decisions about which patients require additional therapy beyond surgery and which can be safely monitored.

In other recent news, Natera, Inc. announced new study results validating its Signatera test for monitoring recurrence and treatment response in early-stage uterine cancer patients. The study, published in the Journal of Clinical Oncology Precision Oncology, analyzed 233 plasma samples from 61 patients with stage I/II uterine cancer who had undergone surgical staging. Additionally, Natera is finalizing its premarket approval application to the FDA for its Signatera test as a companion diagnostic test following positive topline results from the Roche/Genentech-sponsored Phase III IMvigor011 clinical trial in muscle-invasive bladder cancer.

In the realm of analyst ratings, Wells Fargo resumed coverage of Natera with an Equal Weight rating, while Piper Sandler reiterated an Overweight rating, citing significant advancements in Minimal Residual Disease testing. UBS also reiterated its Buy rating following the positive bladder cancer trial results. In legal developments, a North Carolina district court ruled in favor of NeoGenomics, invalidating Natera’s patent claims, which the court deemed as "claiming ineligible subject matter." These recent developments highlight Natera’s ongoing activities and challenges in both clinical and legal arenas.
