Dual immune checkpoint inhibition with the anti–PD-L1 antibody durvalumab (Imfinzi) and the investigational anti–CTLA-4 antibody tremelimumab combined with platinum-based chemotherapy showed promising clinical activity and a favorable safety profile in the neoadjuvant setting for patients with advanced ovarian cancer, according to results of a single-arm phase 2 study presented during the 2022 American Association for Cancer Research annual meeting.
In the year 2020, we have witnessed an unprecedented evolution in medicine, as we adjusted our clinical practices, research programs, and educational vehicles to meet the challenges of the COVID-19 pandemic.
In the phase 2 OVARIO study, median progression-free survival (PFS) has not yet been reached in women with advanced ovarian cancer who are being treated with the combination of niraparib and bevacizumab after response to first-line platinum-based chemotherapy plus bevacizumab. The combination did not appear to cause cumulative toxicities.
Although researchers noted a trend toward increased incidence of secondary hematologic malignancy in patients with newly diagnosed ovarian cancer treated with poly (ADP-ribose) polymerase (PARP) inhibitors, the difference was not statistically significant.
