Sera Prognostics Announces Positive Top-line Data from AVERT PRETERM TRIAL

PreTRM® test-and-treat strategy demonstrates statistically and clinically significant improvement in neonatal health outcomes and hospital length-of-stay

SALT LAKE CITY, Feb. 15, 2023 /PRNewswire/ -- Sera Prognostics Inc., The Pregnancy Company® (NASDAQ: SERA), focused on improving maternal and neonatal health by providing innovative pregnancy biomarker information to doctors and patients, today announced top-line results from the AVERT PRETERM TRIAL (Serum Assessment of Preterm Birth Outcomes Compared to Historical Controls), conducted at ChristianaCare in Wilmington, Delaware.

Both co-primary outcomes—reduction of severe neonatal morbidity or neonatal death; and decreased length of neonatal hospital stay—met their endpoints, and the improvements in outcome with a PreTRM® test-and-treat approach were statistically significant. Detailed results of the AVERT PRETERM TRIAL analysis are being prepared for publication in a peer-reviewed journal.

"The AVERT PRETERM TRIAL results demonstrate the generalizability of the PreTRM® test-and-treat strategy in achieving meaningful clinical results in widely diverse U.S. populations," said Gregory C. Critchfield, MD, MS, Chairman and CEO of Sera Prognostics. "Furthermore, these important AVERT PRETERM TRIAL clinical results build on and reinforce those of past studies—including PAPR, TREETOP and PREVENT-PTB. We believe the AVERT PRETERM TRIAL findings add to the growing body of evidence for the PreTRM® Test's clinical benefit to mothers and babies, and that these new results bode well for our ongoing, large multi-center PRIME study."

The PreTRM® Test was broadly developed and validated for prediction of spontaneous preterm birth (sPTB) in the U.S. in the Proteomic Assessment of Preterm Risk (PAPR) study. In a subsequent large prospective U.S. study, the Multicenter Assessment of a Spontaneous Preterm Birth Risk Predictor (TREETOP), the biomarkers were demonstrated to be predictive of very early preterm birth of any cause, neonatal length of hospital stay, and composite neonatal morbidity/mortality. Additional data published in May 2022 showed improved PreTRM® Test predictive performance for women whose due dates are more reliably determined by ultrasound.

About the AVERT PRETERM TRIAL

The AVERT PRETERM TRIAL evaluated the health benefit afforded to babies when pregnancies are screened with the PreTRM® Test and physicians intervened based on those results. An active arm of approximately 1,453 expectant mothers in the ChristianaCare in Delaware was tested in mid-pregnancy to stratify for increased risk of spontaneous preterm birth risk and those at higher risk were offered evidence-based interventions, which included care management, more intensive education, and medications. A historical control arm of approximately 10,000 patients was drawn from the immediate 2-year period before the trial enrollment began. Important neonatal outcomes that included total neonatal length of hospital stay and composite neonatal morbidity/mortality were analyzed in the active and historical control arms.

About Preterm Birth

Preterm birth is defined as any birth before 37 weeks' gestation and is the leading cause of illness and death in newborns. The 2022 March of Dimes Report Card shows that, for the last four consecutive years, more than one in ten infants is born prematurely. Prematurity is associated with a significantly increased risk of major long-term medical complications, including learning disabilities, cerebral palsy, chronic respiratory illness, intellectual disability, seizures, and vision and hearing loss, and can generate significant costs throughout the lives of affected children. The annual health care costs to manage short- and long-term complications of prematurity in the United States were estimated to be approximately $25 billion for 2016.

About the PreTRM® Test

The PreTRM® Test is the only broadly validated, commercially available blood-based biomarker test that provides an early, accurate and individualized risk prediction for spontaneous preterm birth in asymptomatic singleton pregnancies. The PreTRM® Test measures and analyzes proteins in the blood that are highly predictive of preterm birth. The PreTRM® Test permits physicians to identify, during the weeks 18 through 20 of pregnancy, which women are at increased risk for preterm birth, enabling more informed, personalized clinical decisions based on each woman's individual risk. The PreTRM® Test is ordered by a medical professional.
