Ajay K. Nooka, MBBS, of Winship Cancer Center of Emory University, discusses phase II findings showing that, in patients with high-risk myeloma, maintenance therapy with carfilzomib, pomalidomide, and dexamethasone deepened responses. Measurable residual disease negativity was attained in 80% of patients.
Rami Manochakian, MD, of Mayo Clinic Florida, offers his perspective on the new phase III findings on osimertinib, a third-generation, central nervous system EGFR tyrosine kinase inhibitor, which demonstrated an unprecedented overall survival benefit for patients with EGFR-mutated, stage IB–IIIA non–small cell lung cancer (NSCLC) after complete tumor resection, with or without adjuvant chemotherapy (Abstract LBA3).
Guillermo Garcia-Manero, MD, of The University of Texas MD Anderson Cancer Center, discusses phase III findings from the COMMANDS trial. Compared with epoetin alfa, luspatercept improved red blood cell transfusion independence and erythroid response, as well as the duration of response in erythropoiesis-stimulating agent–naive, transfusion-dependent patients with lower‐risk myelodysplastic syndromes (Abstract 7003).
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).
Shailender Bhatia, MD, of the University of Washington and Fred Hutchinson Cancer Center, discusses phase I/II results on the efficacy of nivolumab with or without ipilimumab in patients with recurrent or metastatic Merkel cell carcinoma. The study found that, for this rare and aggressive skin cancer, nivolumab showed clinical activity in advanced disease. However, these results from CheckMate 358 do not suggest an additional benefit with ipilimumab added to nivolumab (Abstract 9506).
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).
