Key 2025 and Recent Highlights:
Data Generation
Published Landmark PRIME Study Demonstrating PreTRM® Blood Test Reduces Earliest Preterm Births and Newborn Complications: In January 2026, the PRIME Study, a randomized controlled trial of 5,018 women, was published in PREGNANCY, the peer-reviewed journal of the Society for Maternal-Fetal Medicine. Key findings from the Study include:
56% and 32% fewer babies were born before 32 and 35 weeks, respectively
20% fewer babies admitted to the NICU
Fewer health complications for newborns (20% reduction in odds of neonatal morbidity)
A NICU day was saved for every 4.2 patients screened
European Expert Commentary on the PRIME Trial Published in The Journal of Maternal-Fetal & Neonatal Medicine: In March, expert commentary highlighted that current European preterm birth prevention strategies fail to identify most women who deliver preterm and recognizing the PreTRM approach aligned well with European healthcare systems.
Commercial Progress
Expanded Commercial Engagement Across Wave 1 and Wave 2 Target States, Representing Nearly Half of U.S. Pregnancies: Advanced discussions underway with 10 commercial and Medicaid payers across 13 states for PreTRM program adoption, including the addition of a new partner program, bringing the total to two active partner programs.
Expanded U.S. Commercial Organization: Added six field sales staff and Head of Access in anticipation of PRIME publication building momentum.
Advanced Commercialization Preparations for the PreTRM Global Test Across European Markets: Regulatory progress underway toward CE marking and growing clinical validation, including recent European expert commentary recognizing PreTRM as a scalable, cost‑effective approach well suited to publicly funded healthcare systems.
Equity financing
Completed Successful Follow-On Financing Extending Cash Runway Through 2028: In February 2025, Sera completed an underwritten public offering of common stock and pre-funded warrants, including the full exercise of the underwriters' option, generating approximately $57.5 million in gross proceeds before fees and expenses. Net proceeds will support commercial expansion in the U.S., advance preparations for potential EU expansion of the PreTRM Test and fund activities to drive broader market adoption.
Executive Leadership Team and Board of Directors Appointments
Strengthened the Leadership Team and Board of Directors:
In October 2025, Dr. Tiffany Inglis was appointed as Sera's Chief Medical Officer. Dr. Inglis brings extensive clinical and payer-side leadership experience, including at Elevance Health and Carelon Health, where she advanced women's and children's health programs that improved care access and reduced costs. Her background makes her uniquely suited to support Sera's next phase of growth.
In May 2025, Lee Anderson joined Sera as Chief Commercial Officer. He brings over three decades of leadership across sales, marketing, customer service, and strategic accounts, with a proven ability to accelerate growth in healthcare markets. As Sera moves into full commercialization following the PRIME study publication, he will help drive broader adoption of the PreTRM Test.
In March 2025, Sera appointed Jeff Elliott to its Board of Directors. He brings extensive experience in corporate strategy, business operations, analytics, public company finance and commercializing molecular diagnostics. Mr. Elliott's unique background in growing diagnostics businesses is key to Sera in this critical stage of development.
"2025 marked a pivotal year for Sera as we moved from clinical validation to commercial execution," said Zhenya Lindgardt, Sera's President and Chief Executive Officer. "The publication of the landmark PRIME Study delivered strong, peer-reviewed evidence that the PreTRM® Test improves outcomes and reduces costs, creating a compelling value proposition for payers. During the year we expanded engagement across our target states, advanced active discussions with both commercial and Medicaid payers, and invested deliberately in leadership, access and infrastructure to support us as we scale. With a strengthened balance sheet, extending our runway through 2028, we enter 2026 focused on converting this foundation into broader adoption, payer coverage, and measurable impact for the families we serve."
