ASCO 2025 | Identifying clinical trial barriers in melanoma brain metastases research

Zeynep Eroglu, MD, PhD, Moffitt Cancer Center, Tampa, FL, discusses the key barriers facing the treatment of melanoma brain metastases, particularly the lack of standard definition of symptomatic patients. A non-consensus among researchers on defining patients has resulted in clinical trials having inconsistent criteria and frequently excluded symptomatic patients from trials. This interview took place at the 2025 American Society of Clinical Oncology (ASCO) meeting in Chicago, IL.

I think one of our challenges is, so when we define symptomatic melanoma brain metastases, there’s not really a clear consensus definition on what that is, right? For this trial, we defined it as, you know, neurologic symptoms from the brain metastases and or requiring corticosteroids up to 8 milligrams of dexamethasone. Other clinical trials in symptomatic melanoma brain metastases, which are very few, and small cohorts, typically 15, 20 patients, may have defined it in slightly different ways...

I think one of our challenges is, so when we define symptomatic melanoma brain metastases, there’s not really a clear consensus definition on what that is, right? For this trial, we defined it as, you know, neurologic symptoms from the brain metastases and or requiring corticosteroids up to 8 milligrams of dexamethasone. Other clinical trials in symptomatic melanoma brain metastases, which are very few, and small cohorts, typically 15, 20 patients, may have defined it in slightly different ways. So I think to try to advance the research in melanoma brain metastases, and especially those with symptomatic disease who still have poor outcomes, I think we need to come to more of a consensus on how we’re defining these patients, and importantly, to actually conduct trials, right? Because most of the time, patients with symptomatic metastases are automatically excluded from a very large majority of melanoma clinical trials.
