Jason J. Luke, MD, on Melanoma: KEYNOTE-716 Trial of Pembrolizumab vs Placebo
ESMO Congress 2021
Jason J. Luke, MD, of UPMC Hillman Cancer Center, discusses phase III results showing that adjuvant pembrolizumab for patients with resected stage IIB and IIC melanoma decreased the risk of disease recurrence or death by 35% compared with placebo. It was also associated with significantly prolonged recurrence-free survival (Abstract LBA3).
Naveen S. Vasudev, PhD, MBChB, of the University of Leeds, discusses phase II results from the PRISM trial, which showed that giving ipilimumab every 12 weeks instead of every 3 weeks, in combination with nivolumab, led to lower rates of grade 3 and 4 toxicities in patients with advanced renal cell carcinoma. Efficacy appeared to be comparable between both arms (Abstract LBA29).
Nicoletta Colombo, MD, of the Istituto Europeo Oncologico, discusses phase III results that showed improvements in progression-free and overall survival with a combination of pembrolizumab plus chemotherapy, compared with placebo and chemotherapy, for patients with persistent, recurrent, or metastatic cervical cancer. These benefits were seen regardless of PD-L1 expression and concomitant bevacizumab use, suggesting that pembrolizumab plus chemotherapy, with or without bevacizumab, may be a new standard of care for this population (Abstract LBA2).
Hope S. Rugo, MD, of the University of California, San Francisco, discusses phase III results from the KEYNOTE-355 study of pembrolizumab plus chemotherapy, which improved overall survival vs chemotherapy alone in patients with previously untreated locally recurrent, inoperable, or metastatic triple-negative breast cancer whose tumors expressed PD-L1 (Abstract LBA16).
Susana N. Banerjee, MBBS, PhD, of The Royal Marsden NHS Foundation Trust, discusses phase II results of the EORTC-1508 trial, the first study to combine an anti–PD-L1 antibody, atezolizumab, with bevacizumab and the COX1/2 inhibitor acetylsalicylic acid as treatment for patients with ovarian, fallopian tube, or primary peritoneal adenocarcinoma (Abstract LBA32).
Jenny F. Seligmann, MBChB, PhD, of the University of Leeds, discusses phase II findings that suggest adavosertib improved progression-free survival, compared with active monitoring, by inhibiting the WEE1 kinase in patients with RAS- and TP53-mutant metastatic colorectal cancer. In the trial, adavosertib’s activity tended to be even greater in left-sided tumors (Abstract 382O).
