Clinical Trial Summary

The proposed phase 1 clinical trial will investigate the safety and tolerability of 177Lu-CYT-500 in patients with metastatic prostate cancer and determine the optimal antibody mass and dose of 177Lu to be used for further study.


Clinical Trial Description

The proposed phase I clinical trial will investigate the safety and tolerability of 177Lu-CYT-500 and determine the optimal antibody mass and dose of 177Lu to be used for further study. The biodistribution and pharmacokinetics will also be assessed. Patients with histologically documented prostate cancer that is progressing following castration will be eligible. Two antibody masses will be explored in cohort 1 before dose escalation of the 177Lu begins. If the two antibody masses show no difference in pharmacokinetics or biodistribution, then the lower of the doses will be used. The radiation dose will be escalated in subsequent cohorts. Dose escalation will be permitted when the last patient accrued to the previous cohort has demonstrated count recovery in cycle 1 such that DLT has not been defined. ;
