John F ValliantView profile
Professor
John F Valliant is a Professor in the Department of Chemistry and Chemical Biology at McMaster University. His research focuses on radiopharmaceutical chemistry, molecular imaging, and targeted therapies, particularly in cancer diagnostics and therapeutics. He co-founded Fusion Pharmaceuticals, a company acquired by AstraZeneca for $2.4 billion (US), which specializes in targeted alpha therapy for cancer treatment. His work includes developing radiolabeled imaging agents for prostate cancer (e.g., [18F]DCFPyL), targeted alpha therapies (e.g., FPI-1434), and bioorthogonal chemistry strategies for pretargeted imaging. Valliant has contributed to advancements in photoacoustic imaging, SPECT/PET modalities, and theranostic agents for conditions like bacterial infections and bone diseases. Key projects include the Phase II clinical trial using 18F-DCFPyL PET-MRI for oligometastatic prostate cancer and studies on individualized dosimetry in Lu-177 therapies. He has pioneered platforms for radiolabeled antibody-recruiting molecules and fluorous-phase chemistry for high-specific-activity probes. Valliant’s research bridges disciplines, integrating chemistry, biology, and clinical applications to address unmet medical needs in oncology and diagnostic imaging.
