Sera Prognostics Inc., Sonrava Health and Cerebrae are collaborating to provide Sera's PreTRM® Test to members of Sonrava Health's employer-sponsored health insurance program. The PreTRM® Test is the only broadly clinically validated, commercially available blood test that provides an early, individual risk assessment for spontaneous preterm birth in asymptomatic, singleton pregnancies. Sera's PreTRM® Test identifies nearly 90% of pregnancies where spontaneous preterm deliveries will occur, enabling earlier proactive intervention designed to improve the well-being of mothers and babies.

Sonrava Health partners with Cerebrae to evaluate and design their value-based employee healthcare benefits offering. Cerebrae has developed a technology platform that leverages actuarial and data science to accurately forecast financial risk and monitor a healthcare solution's performance. The Cerebrae Platform provides actuarially rigorous risk management capabilities enabling participants it collaborates with, in the healthcare ecosystem, to confidently enter into a value-based arrangement.

Using the Cerebrae Platform, Sonrava Health was able to forecast the financial return on investment (ROI) that inclusion of the PreTRM® Test is expected to provide its employees and their growing families. The PreTRM® Test was developed and validated for prediction of spontaneous preterm birth (sPTB) 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.

Additional new data published in May 2022 showed improved PreTRM® Test predictive performance for women whose due dates are more reliably determined by ultrasound.
