Expert discusses trial evaluating relugolix and enzalutamide in high-risk prostate cancer

In this video, Kelly L. Stratton, MD, FACS, further discusses a phase 1B trial evaluating relugolix (Orgovyx) and enzalutamide (Xtandi) for high-risk prostate cancer. Stratton is an associate professor of urologic oncology at the University of Oklahoma, Oklahoma City.

This is a phase 1B study with no control arm. How will you compare the effectiveness of this regimen with standard treatment options? Are there plans for future comparative studies based on the results of this trial?

The primary aim is looking at the dose-limiting toxicity of this drug combination. We want to make sure that this is safe and effective. We have every reason to believe that this is going to be a highly effective combination. But we want to look at that specifically in this group of patients, because we do have good treatments for these patients. So before we change our practice, we want to evaluate that to ensure that patients are able to tolerate it and we feel like this is a beneficial drug combination. But going forward after this study, we hope to be able to expand and potentially look at patients undergoing either surgery or radiation therapy, and really try to determine the potential benefit. I think, with these studies already showing some signal for activity that if this is a positive study, it will just add to that body of work that shows that combined anti-androgen treatment is helpful in patients who are high risk and at risk for metastatic disease in the future.
