John M. Kirkwood, MD, on Melanoma: Early Study Results on Vidutolimod and Pembrolizumab
John M. Kirkwood, MD, of the University of Pittsburgh Medical Center, discusses phase Ib findings on the combination of vidutolimod plus pembrolizumab, as well as vidutolimod monotherapy, both of which showed clinical activity in patients with PD-1 blockade–refractory melanoma. The duration of response with the combination therapy was substantially longer. Phase II studies are ongoing (Abstract 950).
Mehmet Altan, MD, of The University of Texas MD Anderson Cancer Center, discusses findings from a phase Ib dose-escalation study, which showed early evidence of activity for NKTR-255, an investigational IL-15 receptor agonist, plus cetuximab in patients with solid tumors. Treatment appeared to lead to expansion and proliferation of NK and CD8+ cells (Abstract 957).
Yuki Muroyama, MD, PhD, of the University of Pennsylvania Perelman School of Medicine, discusses the interaction between the immune system and a novel marker—T-cell DNA damage and repair response—to understand how that interaction may affect immune cell biology and therapeutic response (Abstract 310).
Kim A. Reiss, MD, of the University of Pennsylvania, discusses results of a phase I trial of a CAR-M engineered macrophage cancer therapy, known as CT-0508, for patients with solid tumors that overexpress HER2. CAR-M, designed to exploit the natural role of macrophages to initiate an antitumor response, is currently under study at multiple clinical sites (Abstract 951).
Hannah E. Dzimitrowicz, MD, of Duke Cancer Center, discusses study results showing that in patients with melanoma and renal cell cancer receiving immune checkpoint inhibitor therapy, the COVID-19 vaccination appears to be well tolerated and safe. A higher rate of post-vaccination symptoms reported in these patients is likely related to more frequent visits compared with controls (Abstract 625).
Sean Khozin, MD, MPH, of CancerLinQ, discusses the therapeutic advances that have made cancer care more targeted, even as real-world patient outcomes lag behind those reported in clinical trials. Dr. Khozin makes the case for the use of digital decision support tools to advance precision at the point of care.
