Results from the study, JAVELIN Bladder 100, demonstrated that in patients who have achieved stable disease or better after first-line platinum-based chemotherapy, maintenance avelumab significantly improved both progression-free survival and overall survival compared with best supportive care alone.
“RO7198457 in combination with atezolizumab induced immune responses in the majority of patients, including preliminary data demonstrating the detection of neoantigen-specific T-cell responses within the tumor."
The study showed that the development of immune-related adverse events in advanced solid tumors was positively correlated with improved progression-free survival and overall survival in a retrospective analysis, which also showed that Caucasian patients developed immune-related adverse events more frequently than African American patients.
“We don’t have a good understanding of why some patients have a robust response to immunotherapy and others do not. That’s important, not only in terms of selecting patients but also in terms of the therapy approach. This is one reason why clinical trials are incredibly important.”
