Ajay K. Nooka, MBBS, Relapsed or Refractory Multiple Myeloma: Efficacy and Safety Data for Elranatamab
2023 ASCO Annual Meeting
Ajay K. Nooka, MBBS, of Winship Cancer Center of Emory University, discusses findings from a pooled analysis of MagnetisMM studies. The data showed that, in patients with relapsed or refractory multiple myeloma who have not yet been treated with B-cell maturation antigen–directed therapies, elranatamab was efficacious and well tolerated.

Alberto Bossi, MD, of Institut Gustave Roussy, discusses phase III findings showing that combining prostate radiotherapy with systemic treatment did not improve overall survival in men with de novo metastatic castration-sensitive prostate cancer and low metastatic burden. However, best outcomes (radiographic progression–free-survival and overall survival) were observed in men receiving the standard of care plus abiraterone acetate plus prednisone with radiotherapy (Abstract LBA5000).

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).

Penelope Bradbury, MBChB, of Canada’s Princess Margaret Cancer Centre, discusses phase III findings showing that, in patients with treatment-naive unresectable pleural mesothelioma, cisplatin and pemetrexed with pembrolizumab improved median overall survival with acceptable tolerability (Abstract LBA8505).

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).

Manali K. Kamdar, MD, of University of Colorado Hospital, discusses the treatment landscape for the 30% to 40% of patients with diffuse large B-cell lymphoma (DLBCL) whose disease will relapse. Patients who experience relapse within 1 year of chemoimmunotherapy have poor outcomes with autotransplantation, but chimeric antigen receptor T-cell therapy has shown efficacy and manageable toxicity.
