• Flatiron’s research at this year’s conference highlights the ability of scalable, high-quality real-world oncology data and novel rigorous approaches for health outcomes research to support both research and regulatory use cases.

Flatiron Health today announced its presence at ISPOR—The Professional Society for Health Economics and Outcomes Research 2025 Conference, set to take place May 13-16 in Montreal, QC, Canada. Flatiron’s real-world data is featured across 15+ pieces of research to be presented at the conference, including eight Flatiron authored research posters. Additionally, Flatiron will participate in a panel discussion on the role of real-world evidence in precision medicine, including how real-world data can be leveraged across international borders to inform regulatory and reimbursement decisions within diverse healthcare systems.

“At this year’s ISPOR, Flatiron scientists are using high-quality real-world data to validate novel methodologies that will shape the future of evidence generation and health outcomes research in oncology,” said Stephanie Reisinger, Senior Vice President & General Manager, Real-World Evidence. “Leveraging innovative AI and machine learning, Flatiron is expanding the utility of global real-world evidence in regulatory decision-making and across a growing range of oncology use cases at an unprecedented scale.”

Highlights include:

• a poster presentation validating the use of ML to extract real-world response from unstructured data in the electronic health records (EHR), offering a scalable and efficient method for generating high-quality oncology real-world data
• a poster presentation highlighting the acceptance of real-world evidence by the US Food and Drug Administration and the European Medicines Agency, underscoring its potential to complement traditional clinical trial data
• a poster presentation introducing the Flatiron Health Japan Breast Cancer dataset, a novel, de-identified real-world database derived from structured and unstructured data collected from routine oncology care and stored within EHR systems in Japan
