Brown Advisory and T. Rowe Price Associates Join $257M Series B For Thrive Earlier Detection


CAMBRIDGE, Mass.--(BUSINESS WIRE)--Thrive Earlier Detection Corp., a company dedicated to extending and saving lives by incorporating earlier cancer detection into routine medical care, today announced that it has raised $257 million in a Series B financing. The round was led by Casdin Capital and Section 32, with participation from new investors Bain Capital Life Sciences, Brown Advisory, Driehaus Capital Management, Intermountain Ventures, Janus Henderson Investors, Lux Capital, Moore Strategic Ventures, Perceptive Advisors, Rock Springs Capital, Sands Capital, funds and accounts advised by T. Rowe Price Associates, Inc., and other undisclosed investors. All of Thrive’s Series A investors returned to participate in the Series B financing. Thrive also announced that Eli Casdin has been appointed to the board of directors.

“Since our founding in 2019, Thrive has continued to make tremendous progress in our pursuit towards changing the face of cancer,” said David J. Daly, chief executive officer of Thrive. “In April, we published data from the first ever prospective and interventional study of a multi-cancer screening test in an asymptomatic population. Our blood test more than doubled the number of cancers first detected by screening, enabling better outcomes and, in some cases, potential cure for these patients. With this financing, we are well-positioned to advance our test into a robust registrational trial and continue to work closely with key stakeholders to remove barriers to ensure timely access, including future reimbursement for CancerSEEK.”

Thrive’s vision is to incorporate its blood test, CancerSEEK, into routine medical care and detect more cancers at earlier stages when they can be more effectively treated and, in many cases, cured. Today, the vast majority of people are diagnosed only after symptoms appear, often coinciding with late stage, metastatic disease, and poor outcomes. CancerSEEK, used in combination with standard-of-care screening tests has the potential to shift this paradigm to a new reality where the majority of cancers, including many with no screening options today, are diagnosed through screening and at earlier stages.

“We are proud to partner with a diverse group of world class investors who share in our vision to make earlier detection of cancer an accessible and affordable part of our healthcare system,” said Steven J. Kafka, Ph.D., chairman of Thrive and managing partner at Section 32. “We are also thrilled to welcome Eli Casdin to our board of directors. Eli has deep and broad expertise in diagnostics and biotech, and he will provide tremendous value to Thrive.”

Mr. Casdin has spent the last 17 years focused on and investing in disruptive technologies and business models across life sciences and healthcare. In 2011, he founded Casdin Capital, a life science technology investment firm to provide growth equity to private and public companies throughout the industry continuum.

“In the collective search to bend the mortality curve on cancer, the disruptive potential of earlier detection has long been a promise. But now, in a real-world study of 10,000 individuals, Thrive’s blood test integrated with standard-of-care, has delivered on this potential and shows the power of detecting cancers before they spread. While there is more work ahead, it is clear that the future has now arrived. I’m excited to join the board and help in my small way to usher in this new era,” said Eli Casdin, chief investment officer of Casdin Capital.
