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.
Lisa M. DeAngelis, MD, and Ingo K. Mellinghoff, MD, both of Memorial Sloan Kettering Cancer Center, discuss findings from the INDIGO trial showing that the IDH1/2 inhibitor vorasidenib improves progression-free survival for patients with residual or recurrent grade 2 glioma with an IDH1/2 mutation. These data demonstrate the clinical benefit of vorasidenib in this patient population for whom chemotherapy and radiotherapy are being delayed.
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).
Arlene O. Siefker-Radtke, MD, of The University of Texas MD Anderson Cancer Center, discusses phase III findings showing that for patients with advanced or metastatic urothelial carcinoma and FGFR alteration who already had been treated with a PD-(L)1 inhibitor, erdafitinib significantly improved overall and progression-free survival, as well as overall response rate, compared with investigator’s choice of chemotherapy (LBA4619).
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).
