February 06, 2026

Natera, Inc. has launched the EDEN study, a large, multi‑center prospective trial that will enroll up to 7,500 pregnant participants across the United States between 9 and 15 weeks’ gestation. The study is designed to evaluate the company’s integrated prenatal risk‑assessment test, which combines cell‑free DNA (cfDNA), additional analytes and clinical data to provide individualized risk estimates for preeclampsia and other serious pregnancy complications.

The test builds on prior research that linked cfDNA characteristics to pregnancy complications, and it incorporates additional biomarkers and clinical information to improve early detection. By integrating cfDNA with other analytes, the test aims to identify pregnancies at increased risk for early‑onset, severe preeclampsia and other adverse outcomes before clinical symptoms appear.

Strategically, the EDEN study expands Natera’s women’s health platform into a high‑impact clinical area. The preeclampsia diagnostics market was valued at approximately $1.2 billion in 2023 and is projected to reach $1.6 billion by 2032, with a CAGR of about 3%. A successful test could create a new revenue stream and strengthen Natera’s competitive position against established players such as Cedars‑Sinai’s sFlt‑1/PlGF blood test and Labcorp’s trimester‑based screening panels.

The company’s leadership highlighted the significance of the study. Senior Vice President of Medical Affairs Sheetal Parmar said, “For more than a decade, Natera has advanced pregnancy care through highly sensitive, non‑invasive testing. With EDEN, we are evaluating a next‑generation test designed to identify pregnancies at increased risk for preeclampsia and other serious complications earlier and with greater precision, using data that are already part of routine prenatal care.”

If the study demonstrates clinical utility, it could position Natera as a key player in a growing market, complementing its existing cfDNA oncology and organ‑health offerings and reinforcing its broader strategy of leveraging AI and precision medicine to capture new high‑margin opportunities.
