Ryan Cassaday

Ryan Cassaday, MD is a Professor in the Clinical Research Division at Fred Hutchinson Cancer Center and holds a concurrent appointment as Professor in the Division of Hematology and Oncology at the University of Washington School of Medicine. His clinical and research focus centers exclusively on adult acute lymphoblastic leukemia (ALL), where he serves as principal investigator for both investigator-initiated and industry-sponsored clinical trials.

His educational background includes:

• Hematology/Oncology Fellowship from University of Washington/Fred Hutch (2013)
• Internal Medicine Residency from University of Wisconsin Hospital & Clinics (2010)
• MD from University of Wisconsin School of Medicine & Public Health (2007)

Dr. Cassaday specializes in developing novel chemotherapy strategies for high-risk adult ALL populations, including older adults and patients with relapsed/refractory disease. His work prominently features measurable residual disease (MRD) as a critical risk-stratification tool to differentiate disease severity in both standard and experimental therapies. Recent research highlights include a 2024 phase 1 study on chemoimmunotherapy for B-cell ALL and investigations into disease terminology frameworks.
