Narjust Florez, MD, and Ferdinandos Skoulidis, MD, PhD, on NSCLC: Findings on Sotorasib vs Docetaxel in the CodeBreaK 200 Trial
2023 ASCO Annual Meeting
Narjust Florez, MD, of Dana-Farber Cancer Institute, and Ferdinandos Skoulidis, MD, PhD, of The University of Texas MD Anderson Cancer Center, discuss results of a biomarker subgroup analysis, showing that sotorasib demonstrated consistent clinical benefit vs docetaxel in all molecularly defined subgroups of patients with pretreated KRAS G12C–mutated advanced non–small cell lung cancer (NSCLC). Although no predictive biomarkers were confirmed, novel hypothesis-generating signals were observed (Abstract 9008).

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).

Narjust Florez, MD, of Dana-Farber Cancer Institute, and Filippo Gustavo Dall’Olio, MD, of Institut Gustave Roussy, discuss circulating tumor DNA tumor fraction, and its link to survival in patients with advanced non–small cell lung cancer (NSCLC) treated with maintenance durvalumab in the UNICANCER SAFIR02-Lung/IFCT1301 trial. Tumor fraction was positive in 16% of patients randomly assigned to receive durvalumab in the study. This population seems to have a limited benefit from maintenance durvalumab after induction chemotherapy (Abstract 2516).

Tycel J. Phillips, MD, of City of Hope National Medical Center, and Emanuele Zucca, MD, of the Oncology Institute of Southern Switzerland and the International Extranodal Lymphoma Study Group, discuss findings from the largest prospective study of patients with primary mediastinal B-cell lymphoma. The trial data support omitting radiotherapy in patients who achieve complete metabolic response after immunochemotherapy (Abstract LBA7505).

Arlene O. Siefker-Radtke, MD, of The University of Texas MD Anderson Cancer Center, discusses the combination of erdafitinib and cetrelimab, which demonstrated clinically meaningful activity and was well tolerated in cisplatin-ineligible patients with metastatic urothelial carcinoma and fibroblast growth factor receptor alterations (Abstract 4504).

Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, and Lars Henrik Jensen, MD, PhD, of the Danish Colorectal Cancer Center South and the University Hospital of Southern Denmark, discuss phase III results from the Scandinavian NeoCol trial, which showed that neoadjuvant chemotherapy is not superior to standard upfront surgery in terms of disease-free and overall survival in patients with colon cancer, although there are certain circumstances when this approach may have more favorable outcomes (Abstract LBA3503).
