Penelope Bradbury, MBChB, on Pleural Mesothelioma: New Results From the IND227 Trial of Cisplatin and Pemetrexed With or Without Pembrolizumab
2023 ASCO Annual Meeting
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).

Aaron T. Gerds, MD, of Cleveland Clinic Taussig Cancer Institute, talks about treating the anemia many patients with myelofibrosis experience because of JAK inhibitor therapy. The ACE-536-MF-001 study showed that luspatercept improved anemia and transfusion burden in this population, with a safety profile consistent with that in previous studies (Abstract 7016).

Funda Meric-Bernstam, MD, of The University of Texas MD Anderson Cancer Center, discusses interim results from the DESTINY-PanTumor02 trial, the first tumor-agnostic global study of fam-trastuzumab deruxtecan-nxki (T-DXd) in a broad range of HER2-expressing solid tumors. This agent showed an encouraging overall response rate, particularly in patients with IHC 3+ expression; durable clinical benefit; and a manageable safety profile in these heavily pretreated patients. T-DXd may be a potential new treatment option for this population (Abstract LBA3000).

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).

Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, and Thejus Jayakrishnan, MD, of the Cleveland Clinic Taussig Cancer Institute, discuss significant differences in the citrate cycle, a core pathway of cellular metabolism associated with colorectal cancer. Metabolomic differences impacted by environmental exposures (arginine biosynthesis and dietary red meat) were also noted, suggesting possible links with younger age of onset in this disease (Abstract 3510).

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).
