About this study
The purpose of this study is to conduct a Phase I - II clinical trial to extend preclinical studies involving in situ HSV-tk + Valacyclovir gene therapy in combination with brachytherapy for recurrent prostate cancer. This will provide a novel therapeutic approach to prostate cancer and hopefully impact on the development of metastatic disease and the control of preexisting metastasis.
Compensation is read from the study's own description and may be missing — always confirm with the study team.
