Introducing Encompass™: A Breakthrough Solution from Mirvie to Advance Care for Pregnancy Complications

Starting with preeclampsia, new solution aims to transform the pregnancy experience from reactive to personalized, proactive and preventive by predicting risk for complications months before symptoms appear SOUTH SAN FRANCISCO, Calif., May 14, 2025--(BUSINESS WIRE)--Mirvie, a leader in uncovering the biology and utilizing data-driven approaches to improve the care of women's health conditions, today announced the launch of its first breakthrough product for preeclampsia, one of the most common and serious pregnancy complications. Encompass™ combines a novel blood test to predict personalized preeclampsia risk with a preventive action plan and a responsive virtual assistant to offer pregnant women individualized support and help them work with their care team towards the healthiest pregnancy possible. Preeclampsia, impacting 1 in 12 pregnancies with rates continuing to grow, is one of the most challenging pregnancy complications, but also one with a comprehensive, evidence-based care plan to reduce the risk of developing the condition or delaying onset late enough in pregnancy to avoid preterm birth. Until now, no simple and effective clinical tools have existed to predict the risk of who will develop the condition. As a result, prenatal care has relied on a 'wait and see' approach that looks for symptoms and then reacts once the condition develops. This lack of specificity results in poor consumer attitudes and clinical resource constraints – explaining why adherence of preventive interventions such as daily aspirin is less than 10%. "For too long, we've relied on an outdated prenatal care model which has not kept up with the precision medicine approach common in other medical specialties," said Maneesh Jain, CEO and Co-Founder of Mirvie. "Over the past decade, Mirvie has combined technological innovation with rigorous clinical evidence to deliver biological-data-driven approaches that usher in the era of predictive and preventive prenatal care. We're thrilled that we can now help families with our work." Mirvie's Encompass test for preeclampsia analyzes cell-free RNA measurements to evaluate placental health and the biology of the developing pregnancy to predict which pregnancies are at risk for preeclampsia. Studied in landmark research and powered by the Mirvie RNA platform™, which examined the molecular health of nearly 11,000 pregnancies across the U.S., the test predicted 9 of 10 pregnancies that later developed preterm preeclampsia as "high risk." Those with a "low-risk" result have a 99.7% probability of not developing preterm preeclampsia. "Patients should know their preeclampsia risk before it becomes a crisis," said Dr. Thomas McElrath, Vice President of Clinical Development at Mirvie and a practicing maternal-fetal medicine physician at Brigham and Women's Hospital. "The prenatal care model - designed nearly 100 years ago to manage preeclampsia - has remained largely unchanged. Encompass is a paradigm shift based on an increased understanding of the underlying biology of pregnancy. With Encompass, pregnant women with a high-risk result can have conversations with their care teams about interventions to mitigate risk, including additional monitoring, aspirin adherence, monitoring blood pressure at home, and more. Encompass allows optimal, personalized care for the right patients." Mirvie is launching Encompass across the U.S.* with an easy, direct-to-consumer online purchase process, telehealth clinician review, mobile phlebotomy, and results delivered within 10-14 days. Initially, Encompass is available to purchase for expecting moms ages 35 and older at delivery without pre-existing high-risk conditions for preeclampsia. The company is also working with third parties, including physician offices, maternal health benefits providers, and payers to add new access channels. "With this launch, we are moving urgently to respond to the dire maternal health crisis and also embracing very positive structural changes happening in healthcare," said Aimee Corso, Senior Vice President of Growth at Mirvie. "Consumer demand and willingness to pay for innovation are at an intersection with constrained OB/GYN resources and the clinical movement to personalize maternity care. Our easy, patient-centric, ecommerce experience helps expectant moms meet their needs while also reducing burdens on their providers, enabling the most productive office visits possible." A few things to know about Encompass: Accessible: Purchasing the test is simple — pregnant individuals age 35 or older (at time of delivery) can purchase from and a licensed telehealth provider will review and approve the test order. Simple and convenient: A simple blood sample is collected through an at-home visit between 18-22 weeks of gestational age, without needing a trip to the lab. Actionable: Results are returned within 10-14 days to the mom and her provider care team, paired with a preventive action plan and responsive virtual assistant, to help reduce the risk of developing preterm preeclampsia. As part of the product launch and with May marking Preeclampsia Awareness Month, Mirvie is also announcing the launch of the #MotherofAllQuestions campaign to shed light on how expecting moms can prepare themselves with the right solutions, data, and questions to have authentic conversations with their providers about their pregnancy journey and understand their risk for dangerous complications like preeclampsia.

Advantia Health Partners with Mirvie to Bring Predictive and Preventive Care to Maternal Health

Encompass™ RNA test to help stratify asymptomatic pregnant women into high or low risk for preeclampsia, and support early preventive care interventions ARLINGTON, Va. & WASHINGTON & SOUTH SAN FRANCISCO, Calif., April 22, 2025--(BUSINESS WIRE)--Mirvie, Inc., in partnership with Advantia Health, has launched a first-of-its-kind pilot program in the U.S. to improve pregnancy outcomes. The program uses the clinically validated Encompass Preeclampsia Test (powered by the Mirvie RNA Platform) to assess high and low risk for preeclampsia, enabling clinicians to initiate preventive care for the appropriate patients. Preeclampsia, a dangerous pregnancy complication, has nearly doubled in recent years and now affects 1 in 12 pregnancies, costing the U.S. healthcare system billions each year. Current risk assessment methods have proved ineffective, leading to high rates of preterm deliveries, neonatal ICU admissions, and preventable deaths. "The potential to impact pregnancy health is huge. We have been operating without objective data. This test allows us to identify and focus on the few patients at truly high risk with a preventive care plan," said Dr. Jo'Ann Jackson, Regional Chief Medical Officer of the Mid-Atlantic, Advantia Health. "Until now, we have lacked an effective and objective test to assess risk for preeclampsia in patients with no known risk factors. The Encompass test helps resolve this ambiguity of risk, ensuring the right pregnancies get the right preventive care. We are bringing a level of personalized care, based on molecular signatures, that has been long available in oncology, but for the first time can now be brought to pregnancy care," said Dr. Thomas McElrath, Vice President of Clinical Development at Mirvie, and practicing physician in Maternal Fetal Medicine at Brigham and Women's. "We know innovations in maternal health are needed," said Dr. Michael Udwin, Medical Director, CareFirst BlueCross BlueShield (CareFirst). "We are excited about the potential for improved outcomes for both mother and baby through Mirvie's collaboration with Advantia Health, which provides care to many CareFirst members." This year-long collaboration, which launches immediately, reflects Advantia Health's commitment to improving pregnancy outcomes in the mid-Atlantic region and Mirvie's commitment to bringing a precise standard of care to pregnancy health. About Mirvie Mirvie is bringing scientifically rigorous and data-driven approaches to solving some of the most pressing clinical problems in women's health, beginning with pregnancy. Serious complications impact one in five pregnancies in the U.S., and Mirvie is committed to creating a world where every pregnancy is as safe and healthy as possible.

Mirvie Announces Results from Largest Molecular Study in Pregnancy and Clinical Validation of Simple Blood Test to Predict Risk for Preeclampsia Months Before Symptoms

Landmark research published in Nature Communications advances the biological understanding of hypertensive disorders of pregnancy, unlocking the potential for personalized care SOUTH SAN FRANCISCO, Calif., April 08, 2025--(BUSINESS WIRE)--Today, Mirvie announced results of a breakthrough study published in Nature Communications, revealing new advances in the biological understanding of hypertensive disorders of pregnancy (HDP), including preeclampsia - a leading cause of maternal morbidity and mortality as well as preterm birth. Researchers used data from more than 9,000 pregnancies within the multi-center Mirvie-sponsored Miracle of Life prospective study to discover and validate RNA signatures capable of distinguishing between severe and mild hypertensive disorders of pregnancy, including preeclampsia, months before symptoms occur. The paper also validates the predictive performance of Mirvie's simple blood test to predict preeclampsia early, at 17.5 to 22 weeks gestational age, in pregnancies without any pre-existing high-risk conditions. "By the time a patient is symptomatic, it's a race against the clock to try to get the baby to term and not risk the mother's health," said Dr. Kara Rood, a maternal-fetal medicine physician, one of the principal investigators of the study, and Clinical Associate Professor of Obstetrics and Gynecology at The Ohio State University Wexner Medical Center. "Current guidelines are not helping us identify which patients are truly at high risk and we need better tools. Mirvie's preeclampsia risk prediction test can now improve risk assessment, helping women and their care teams be informed and take actions with the potential to delay onset or prevent the disease." Despite current guidelines from U.S. Preventive Services Taskforce and The American College of Obstetricians and Gynecologists that use general maternal characteristics to identify pregnant women at increased risk for preeclampsia, rates of the disease have nearly doubled in the last decade and now affect 1 in 12 pregnancies. Mirvie's blood test uses RNA signatures to resolve this ambiguity, helping pregnant women and their providers focus on the 1 in 4 pregnancies that are truly at high risk, ensuring optimal care for the right patients. The results of this study demonstrate that relying on molecular signals from the underlying biology is far more effective in determining whether risk for preeclampsia is high or low. Validation results show the simple blood test can identify 91% of pregnancies that will develop preterm preeclampsia in women aged 35+ without pre-existing high-risk conditions, months ahead of symptoms. Those with a low-risk result have 99.7% probability of not developing preterm preeclampsia. The clinically validated blood test will soon be broadly available under the brand name Encompass™. "Over the last 100 years, we have relied on a reactive care model in pregnancy. This study represents a profound opportunity to move toward a proactive care model," said Dr. Thomas McElrath, vice president of clinical development at Mirvie and a maternal-fetal medicine physician at Brigham and Women's Hospital in Boston, MA. "Importantly, these results demonstrate for the first time the unique molecular signatures that distinguish between severe and mild hypertensive disorders of pregnancy, giving us confidence in a much more precise and personalized approach for at-risk pregnancies." Today, the adherence to known valuable interventions for pregnancies at high risk of preeclampsia such as daily aspirin is less than 50%, even among high-risk patients. With a simple blood test available early in the second trimester, pregnant patients and care teams can intervene months before symptoms and more confidently implement an evidence-based prevention care plan to improve the chance for a full-term pregnancy and healthy delivery. "We are thrilled with the results from our investments in this critical research and collaboration with more than a dozen internationally renowned experts in maternal-fetal medicine," added Maneesh Jain, co-founder and CEO of Mirvie. "Much like the discovery of molecular subtypes of breast cancer led to improved outcomes, the discovery of molecular subtypes in HDP offers a bright future for personalizing pregnancy care and addressing the rising rates of births with complications." The novel findings add to the growing body of research demonstrating the use of the Mirvie RNA platform to predict pregnancy complications months in advance, including studies on preeclampsia risk prediction in Nature and preterm birth risk prediction in the American Journal of Obstetrics and Gynecology and research presented in January at the Society for Maternal-Fetal Medicine conference on prediction of fetal growth restriction.
