Carmen E. Guerra, MD, MSCE, on Diversity, Equity, and Inclusion in Clinical Trials: Expert Commentary
2023 ASCO Annual Meeting
Carmen E. Guerra, MD, MSCE, of the University of Pennsylvania Abramson Cancer Center, discusses three key abstracts presented at ASCO: strategies to increase accrual of underrepresented populations in Alliance NCTN trials, how patient-clinician education can strengthen partnerships and improve diversity in breast and lung cancer trials, and mediators of racial and ethnic inequities in clinical trial participation among U.S. patients with cancer from 2011 to 2022 (Abstracts 6509, 6510, 6511).

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).

Enrique Grande, MD, of The University of Texas MD Anderson Cancer Center, discusses new findings that show initial responses to induction therapy with atezolizumab plus platinum and gemcitabine did not seem to impact overall survival for patients with metastatic urothelial carcinoma. Cisplatin-treated patients appeared to derive a greater benefit with atezolizumab than did carboplatin-treated patients (Abstract 4503).

Jonathan W. Riess, MD, of the University of California, Davis Comprehensive Cancer Center, explores the findings of three important clinical trials in lung cancer treatment: whether to incorporate immune checkpoint inhibitors into the treatment of EGFR-mutated lung cancer, the importance of central nervous system activity in EGFR-mutant lung cancer, and new therapies for disease with EGFR exon 20 insertion.

Allison Betof Warner, MD, PhD, of Stanford University Medical Center, and Zeynep Eroglu, MD, of H. Lee Moffitt Cancer Center and Research Institute, discusses phase II findings showing that in patients with BRAF-mutant metastatic melanoma, dabrafenib plus trametinib and navitoclax (DTN) was associated with a complete response rate of 20% and an overall response rate of 84%. Additionally, there was a trend toward improved overall survival in patients treated with DTN compared with dabrafenib plus trametinib alone; the difference in overall survival was more pronounced in patients with a smaller tumor burden (Abstract 9511).

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).
