A late-breaking abstract presented at the 2025 American Society of Clinical Oncology Annual Meeting (LBA3) showed that rusfertide significantly increased hematocrit control and improved symptoms for patients with polycythemia vera, a chronic leukemia. “We thought if we could use our understanding of iron regulation, then we could change the game a little bit,” said Andrew Kuykendall, MD, assistant member in the Department of Malignant Hematology at the Moffitt Cancer Center in Tampa, Florida. He told Robert A. Figlin, MD, the interim director of Cedars-Sinai Cancer in Los Angeles and Steven Spielberg Family Chair in Hematology-Oncology, about the rationale behind the trial, broke down key findings, and shared what comes next in this area of research. “I think it is very important that we continue to follow these patients. And this is an ongoing trial that has a part two to it, which is a long-term safety assessment period,” he explained.
