Clifford A. Hudis, MD, ASCO Chief Executive Officer, talks about extending the reach and impact of ASCO by partnering with patients who play a key role in advancing science through clinical trial participation. With near-record numbers of registered attendees, the 2023 Annual Meeting fostered new connections and plans for collaborations.
Omid Hamid, MD, of The Angeles Clinic & Research Institute, discusses study findings on fianlimab plus cemiplimab-rwlc, which showed clinical activity in patients with advanced melanoma, comparing favorably with other approved combinations of immune checkpoint inhibitors in the same clinical setting. This is the first indication that dual LAG-3 blockade may produce a high level of activity with significant overall response rate after adjuvant anti–PD-1 treatment. A phase III trial of this regimen in treatment-naive patients with advanced melanoma is ongoing (Abstract 9501).
Allison Betof Warner, MD, PhD, of Stanford University Medical Center, and Adnan Khattak, MBBS, FRACP, PhD, of Australia’s Hollywood Private Hospital & Edith Cowan University, discuss the use of the mRNA-4157 vaccine in combination with pembrolizumab as adjuvant therapy for resected high-risk melanoma, which prolonged distant metastasis–free survival compared with pembrolizumab alone. These results provide further evidence that a personalized neoantigen approach is potentially beneficial (Abstract LBA9503).
Nagla Abdel Karim, MD, of the Inova Schar Cancer Institute, University of Virginia, discusses phase II data showing that maintenance atezolizumab plus talazoparib improved progression-free survival in Schlafen-11–selected patients with extensive-stage small cell lung cancer. This study demonstrated the feasibility of conducting biomarker-selected trials in this disease, paving the way for future evaluation of novel therapies in selected populations (Abstract 8504).
Amer Methqal Zeidan, MBBS, MHS, of Yale University and Yale Cancer Center, discusses phase III findings on the first-in-class telomerase inhibitor imetelstat, which was given to patients with heavily transfusion-dependent non-del(5q) lower-risk myelodysplastic syndromes that are resistant to erythropoiesis-stimulating agents. Imetelstat resulted in a significant and sustained red blood cell (RBC) transfusion independence in 40% of these heavily transfused patients. The response was also durable and accompanied by an impressive median hemoglobin rise of 3.6 g/dL, and seen in patients with and without ring sideroblasts. Importantly, reduced variant allele frequency was observed in the most commonly mutated myeloid genes which correlated with duration of transfusion independence and hemoglobin rise, therefore suggesting a disease-modifying potential of this agent (Abstract 7004).
Claire Roddie, PhD, MBChB, of University College London, discusses results of the FELIX study, which showed that the second-generation chimeric antigen receptor (CAR) T-cell therapy obecabtagene autoleucel is safe for adults with relapsed or refractory B-cell acute lymphoblastic leukemia, even those with a high burden of disease. This agent yielded high rates of complete response and ongoing CAR T-cell persistence in most patients whose disease responded (Abstract 7000).
