Results show that the validated proteomics predictor has even greater predictive performance to determine risk of spontaneous preterm birth
SALT LAKE CITY, May 19, 2022 /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 the publication of improved PreTRM® test performance using women from the Proteomic Assessment of Preterm Risk (PAPR) clinical study whose pregnancy outcomes are aligned with updated ACOG gestational age dating guidelines. The newly published article reports:
- A greater observed sensitivity of 88% at 75% specificity, which represent increases of 17% and 1%, respectively, relative to all subjects
- An improved performance was also demonstrated over an expanded 18-20 weeks' gestational age time interval for performing PreTRM testing, consistent with the timeframe of routine obstetric visits during pregnancy
- A negative predictive value of 99% for the test, at its validated threshold
"Beyond increased performance, these data show that the PreTRM® test can also be offered more conveniently to women over a broader time interval during pregnancy, typically months before preterm delivery occurs," said Michael Foley, MD, Sera's Chief Medical Officer. "A PreTRM® test higher risk result reflects a similar risk as is revealed by traditional assessment techniques, but the PreTRM® test identifies far more patients who are at risk of premature delivery. Furthermore, the reported 99% negative predictive value of the PreTRM® test means that women not found to be at higher risk of preterm delivery can have very high confidence of not delivering a premature infant."
"These new data demonstrate substantially improved PreTRM® test predictive performance over an expanded blood draw window when gestational age is known with more accuracy, as the first and only broadly validated commercially available blood test for prematurity risk is made even more available to physicians and their patients," said Gregory C. Critchfield, MD, MS, Chairman and CEO of Sera Prognostics. "Sera's pioneering work in the pregnancy space highlights the power of our proteomics and bioinformatics approach to provide valuable information to women and their physicians to enable proactive care in a greater number of pregnancies that are truly at higher risk of preterm delivery."
The PreTRM® test was developed and validated for prediction of spontaneous preterm birth broadly 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, length of neonatal hospital stay, and neonatal morbidity and mortality. The new data reported here, "Better Estimation of Spontaneous Preterm Birth Prediction Performance Through Improved Gestational Age Dating" (https://www.mdpi.com/2077-0383/11/10/2885/htm), were published as a peer-reviewed article in the Journal of Clinical Medicine, showing that the PreTRM® test provides highly accurate predictions that are confirmed when outcomes are known more reliably.

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 2021 March of Dimes Report Card shows that 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 19th or 20th week 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.
