SALT LAKE CITY, March 22, 2023 — 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 financial results for the fourth quarter and full year 2022 ended December 31, 2022.

Recent Highlights:

  • Announced positive top-line results from the AVERT PRETERM TRIAL (Serum Assessment of Preterm Birth Outcomes Compared to Historical Controls), conducted at ChristianaCare in Wilmington, Delaware. The results demonstrated the generalizability of the PreTRM® test-and-treat strategy in achieving meaningful clinical results in widely diverse U.S. populations toward significant improvement in neonatal health outcomes and hospital length-of-stay.
  • Announced the publication of results from a clinical utility and cost-effectiveness modeling study, ACCORDANT (Analyses aCross Congruent studies ReDucing Adverse pregNancy ouTcomes), which, based on rigorous clinical utility health economic analysis, illustrated the impact of Sera’s test-and-treat strategy and its specific benefits in underserved racial and ethnic populations. By combining the PreTRM® Test with enhanced prenatal care management, real progress may be possible in better serving these populations to enable better medical outcomes.
  • Validated preeclampsia risk predictor, with results made available publicly and being prepared for submission to a scientific journal.
  • Surpassed the required 2,800 PRIME study subject enrollment, which enables the interim look analysis by year end.

“We are pleased with the growing body of data showing the clinical utility and cost effectiveness of the PreTRM® Test in mitigating the negative health and economic consequences of preterm delivery,” said Gregory C. Critchfield, MD, MS, Chairman and CEO of Sera Prognostics. “The exciting AVERT PRETERM TRIAL results are being prepared for submission to a scientific journal for publication. We believe this provides meaningful evidence of the value of our test in improving the health of moms and babies. We are excited to pursue our mission to work with doctors, patients and health systems in creating a better standard of care in pregnancies.”

Selling, general and administrative expenses for the fourth quarter of 2022 were $6.9 million, down significantly from $9.5 million for the year-ago period due primarily to steps we took during the prior quarter to streamline our sales operations and to better focus our commercial strategy in response to market dynamics, as well as decreased administrative costs resulting from operational efficiencies.

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 and its complications, enabling more informed, personalized clinical decisions based on each woman’s individual risk. The PreTRM® Test is ordered by a medical professional.
