Official title
A First-in-Human, Pilot PET Imaging Study of 89Zr-DFO-YS5, an immunoPET Agent for Detecting CD46 Positive Malignancy in Men With Prostate Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
CD46 is an exciting new therapeutic target in prostate cancer, with the antibody drug conjugate FOR46 under investigation in phase I clinical trials. The hypothesis of the study is that CD46 expression, measured via our novel imaging biomarker, is a characteristic feature of mCRPC, and particularly common in the most lethal forms of the disease including adenocarcinoma and Small-cell neuroendocrine carcinoma (SCNC). These data will provide crucial information about the feasibility of targeting cluster of differentiation 46 (CD46) in mCRPC, will be used guide the development of novel therapeutic and theranostic agents, to help develop treatments that improve outcomes for men with the most lethal forms of prostate cancer.
