Petranha Azd5305 New Hormonal Agents

ClinConnect Summary

This clinical trial is studying a new medication called AZD5305 and its effects when used alongside popular hormonal treatments for metastatic prostate cancer, which is cancer that has spread beyond the prostate. The goal is to understand how safe the combination is, how the body processes it, and whether it works to help control the cancer. The trial is currently recruiting male patients aged 18 and older who have been diagnosed with metastatic prostate cancer and are candidates for treatments like enzalutamide or abiraterone.

Eligible participants will need to be in good overall health and have a life expectancy of at least 16 weeks. They should also be medically castrated, meaning their testosterone levels have been lowered to help manage the cancer. Throughout the trial, participants will receive regular check-ups to monitor their health and the effects of the treatment. It's important for interested patients to talk with their doctors to see if they qualify and to understand any potential risks or commitments involved in participating.
