ClinConnect Summary

This clinical trial is studying the long-term safety of a medication called Enzalutamide in men with prostate cancer who have previously participated in a related study. The goal is to see how well the medication continues to work for those who are still benefiting from it. If you are a male between the ages of 65 and 74 and have been receiving Enzalutamide in a study sponsored by Astellas or Medivation, you might be eligible to participate. To qualify, you need to be able to continue taking the same treatment you were on in the previous study and agree to follow specific guidelines, such as using two forms of birth control if you have a female partner who could become pregnant.

If you join the study, you can expect to keep taking Enzalutamide and attend regular appointments to monitor your health and response to the treatment. It’s important to note that you should not participate in any other clinical trials while in this study, and there are specific health criteria that might prevent you from joining. This trial is actively recruiting participants, and it represents an opportunity to contribute to understanding the ongoing effects of Enzalutamide in prostate cancer treatment.
