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).

Catherine C. Coombs, MD, of the University of California, Irvine, discusses prolonged pirtobrutinib therapy, which continues to demonstrate a safety profile amenable to long-term administration at the recommended dose without evidence of new or worsening toxicity signals. The safety and tolerability observed in patients on therapy for 12 months or more were similar to previously published safety analyses of all patients enrolled, regardless of follow-up (Abstract 7513).

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).

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).

Rana R. McKay, MD, of the University of California, San Diego, and Toni K. Choueiri, MD, of Dana-Farber Cancer Institute and Harvard Medical School, discuss results from the phase III CONTACT-03 study, showing that, for patients with metastatic renal cell carcinoma (RCC), adding the PD-L1 inhibitor atezolizumab to cabozantinib did not improve clinical outcomes compared with treatment with cabozantinib alone. In addition, higher toxicities were observed in the combination arm (Abstract LBA4500).

Jennifer A. Woyach, MD, of The Ohio State University Comprehensive Cancer Center, discusses results of a phase III study showing that progression-free survival with ibrutinib plus obinutuzumab plus venetoclax is not superior to ibrutinib plus obinutuzumab for treatment-naive older patients with chronic lymphocytic leukemia (CLL) in the setting of the COVID-19 pandemic. Long-term follow-up will determine whether there are advantages to obinutuzumab plus venetoclax, with special attention to measurable residual disease and therapy discontinuation (Abstract 7500).
