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).

Nirav N. Shah, MD, of the Medical College of Wisconsin, discusses the efficacy and safety of pirtobrutinib, a highly selective, noncovalent BTK inhibitor, studied for more than 3 years in the BRUIN trial. The results showed that the use of pirtobrutinib continues to have durable efficacy and a favorable safety profile in heavily pretreated patients with relapsed or refractory mantle cell lymphoma and prior BTK inhibitor therapy. Responses were observed in patients with high-risk disease features, including blastoid/pleomorphic variants, elevated Ki67 index, and TP53 mutations (Abstract 7514).

Sarah K. Tasian, MD, of Children’s Hospital of Philadelphia, summarizes three studies presented at ASCO: genomic determinants of outcome in acute lymphoblastic leukemia (ALL), a phase III trial of inotuzumab ozogamicin for high-risk B-cell ALL, and preliminary results from the first-in-child phase II trial of bosutinib in pediatric patients with newly diagnosed chronic myeloid leukemia (Abstracts 10015, 10016, and 10017).

Reid Merryman, MD, of Dana-Farber Cancer Institute, discusses his findings on the regimen of epcoritamab plus rituximab and lenalidomide for patients with high-risk follicular lymphoma. Regardless of whether their disease progressed within 24 months of first-line chemoimmunotherapy, this regimen showed antitumor activity and a manageable safety profile in patients with relapsed or refractory disease. Epcoritamab, a subcutaneous T-cell–engaging bispecific antibody, may abrogate the negative effects of high-risk features (Abstract 7506).

Jennifer L. Crombie, MD, of Dana-Farber Cancer Institute, discusses the historically poor outcomes for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). Her study examined real-world data on the use of novel therapies in this population and found that outcomes with second- and third-line regimens of polatuzumab vedotin-piiq plus bendamustine and rituximab and tafasitamab plus lenalidomide remain suboptimal, with worse outcomes particularly after chimeric antigen receptor T-cell therapy (Abstract 7552).

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).
