David Reardon, MD, on Glioblastoma: A Microbiome-Based Vaccine, Nivolumab, and Bevacizumab
SITC 2022
David Reardon, MD, of Dana-Farber Cancer Institute, discusses phase I/II results from the EOGBM1-18/ROSALIE study, which showed the EO2401 vaccine plus nivolumab generated systemic immune responses correlating with efficacy in patients with recurrent glioblastoma. Adding bevacizumab to this combination appeared to improve efficacy. (Abstract 642).

Talal El Zarif, MD, of Dana-Farber Cancer Institute, and Abdul Rafeh Naqash, MD, of Stephenson Cancer Center at The University of Oklahoma, discuss the results of their cohort study of patients living with HIV and metastatic non–small cell lung cancer, who are often underrepresented in clinical trials, and the safety and efficacy of treating this unique population with immune checkpoint inhibitors (ICIs). The data showed that patients living with HIV and lung cancer had similar toxicity profiles and clinical outcomes as did those who did not have HIV and received ICIs (Abstract 437).

Michael A. Postow, MD, of Memorial Sloan Kettering Cancer Center, discusses new findings on the correlation between CD8 cell PET imaging with zirconium-89–crefmirlimab berdoxam and CD8 cell immunohistochemistry in patients with advanced cancer receiving immunotherapy. Noninvasive CD8 PET scanning with crefmirlimab berdoxam permits whole-patient, longitudinal CD8 assessment, which is currently under investigation as a biomarker for immunotherapy responsiveness and may be a useful tool for immunotherapy development and clinical management (Abstract 1472).

Antoni Ribas, MD, PhD, of the University of California, Los Angeles, discusses a phase I study that used CRISPR gene editing to simultaneously “knock out” endogenous T-cell receptors and replace them with personalized neoantigen T-cell receptors in patients with solid tumors. The edited TCR T-cell products were safely infused and trafficked to the tumor lesions (Abstract 1478).

Roger Li, MD, of the H. Lee Moffitt Cancer Center, discusses results from a phase II single-arm study of CG0070, a cancer-selective oncolytic adenovirus that creates mechanistic synergy with immune checkpoint blockade. In this trial, the virus was combined with pembrolizumab in patients with non–muscle-invasive bladder cancer that is unresponsive to bacillus Calmette-Guérin. At 3 months, 88% of the 35 patients enrolled achieved a complete response (Abstract 666).

Wade T. Iams, MD, of Vanderbilt University Medical Center, discusses phase II efficacy results from the first-line non–small cell lung cancer cohort of the TACTI-002 study. The results suggest that when combined with pembrolizumab, eftilagimod alpha yielded encouraging efficacy across all PD-L1 levels, including patients with PD-L1 low and PD-L1 negative disease (Abstract 1470).
