Data Predicting Clinical Utility & Cost Effectiveness of PreTRM® Test

– Clinical and economic benefits of the PreTRM^® test and treat strategy illustrated amongst diverse racial and ethnic backgrounds –

SALT LAKE CITY, Nov. 15, 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 results from a clinical utility and cost-effectiveness modeling study, ACCORDANT (Analyses aCross Congruent studies ReDucing Adverse pregNancy ouTcomes). The newly published study reports:

Case management, which consists of increased outreach, education, and specialist care for women predicted to be at higher risk for delivering prematurely, was expected to decrease neonatal and maternal hospital length of stay by 19% (p=0.029) and 8.5% (p=0.001), respectively, compared with standard care.
Case management for those at higher risk also was predicted to significantly reduce moderate-to-severe neonatal morbidity and mortality by 29% (p=0.025).
Multimodal management, which combines case management with pharmacological treatment, was predicted to further improve outcomes and statistical significance
The modeled clinical benefits and cost-effectiveness of the test-and-treat strategies were seen across diverse racial and ethnic backgrounds, with Black and Hispanic women strongly represented in the study.

“Results of this analysis point to the utility of the PreTRM^® test-and-treat strategy in ameliorating the clinical and economic effects of preterm delivery, which impacts more than 10% of U.S. births each year,” said Gregory C. Critchfield, MD, MS, Chairman and CEO of Sera Prognostics. “Most importantly, the predicted benefits across underserved populations, among whom the prevalence of preterm birth is disproportionately increased, provide the opportunity to serve a broad and diverse population of women in the United States. We are excited to be in a position to help substantively address unacceptable healthcare disparities in pregnant populations that unfortunately bear the burdens of prematurity.”

“By combining the PreTRM^® Test, which detects far more women at risk of preterm birth than traditional clinical factors, with enhanced prenatal case management, real progress may be possible for this under-addressed and serious condition,” said Michael Foley, MD, Sera’s Chief Medical Officer.

ACCORDANT was a secondary analysis of 847 women from the Multicenter Assessment of a Spontaneous Preterm Birth Risk Predictor study (TREETOP), a previously published evaluation of the predictive performance of the PreTRM^® Test. The study combined real-world clinical information with large, published outcomes datasets in a microsimulation model to examine the potential impacts of the test-and-treat strategies on important clinical indicators and medical costs related to preterm birth.

The peer-reviewed report, “Clinical and economic evaluation of a proteomic biomarker preterm birth risk predictor: Cost-effectiveness modeling of prenatal interventions applied to predicted higher-risk pregnancies within a large and diverse cohort,” was published in the Journal of Medical Economics.

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 enables physicians to identify, during the 18th through the 20th week of pregnancy, which women are at increased risk for preterm birth, driving more informed and personalized clinical decisions based on each woman’s individual risk. The PreTRM^® Test is ordered by a medical professional.
