Cancer
MiniRaP-00
A feasibility study of the repurposing of prazosin to improve treatment outcomes in men receiving radiotherapy for prostate cancer (MiniRaP-00).
Trial overview
Topic
Prostate cancer
Study details
The purpose of this study is determine whether it is possible to use a drug called prazosin when men are undergoing radiotherapy for the treatment of prostate cancer.
All participants in this study will be asked to take prazosin two times day starting the week before and until the completion of their radiotherapy treatment for prostate cancer. The dose of medication provided will increase week by week until the final week.
Participants will be monitored throughout the treatment period to determine if they are willing to take the medication alongside their radiation, and followed for 9 months for any side effects.
It is hoped that this study will help determine if it is possible to use prazosin while participants are completing radiotherapy, and help guide the development of a large scale clinical trial which will be used to investigate the efficacy of prazosin combined with radiotherapy.
